The rotary seat 200 can be pushed to be turned upwards by the elastic force of the torsion spring, and in particular, when the driving member 500 releases the rotary seat 200, the rotary seat 200 is pushed to reversely rotate around the rotating shaft 202 by the elastic force of the torsion spring, so that the comb 300 is retracted into the housing 100.
Further, the driving member may be a knob connected to the rotating shaft 202, a push block penetrating through the housing 100, or an electric cam structure and a lever structure.
Further, referring to another embodiment of the driving member 500 of fig. 2 to 10, specifically, the driving member 500 of the present embodiment includes a pushing member 510, a pushing member 520 and a connecting member 530. The pushing member 510 is slidably disposed in the housing 100, the housing 100 is provided with a clearance groove 106, one end of the connecting member 530 is connected to the pushing member 510, and the other end passes through the clearance groove 106 to be connected to the push-pull member 520.

The rotary seat 200 has a pushing surface 204, and the front end of the pushing member 510 extends to form a pushing portion 511 for abutting against the pushing surface 204, and pushes the push-pull member 520 to translate the pushing member 510 in the mounting cavity 101, so that the pushing portion 511 can abut against the pushing surface 204 and push the pushing surface 204, and the rotary seat 200 turns downward against the spring force of the torsion spring.
Still further, the housing 100 includes a top case 110 and a bottom case 120 that are mutually covered.

In the sliding process of the pushing member 510, when the pushing portion 511 contacts with the pushing surface 204, the arc surface 512 at the front side of the pushing portion 511 contacts with the pushing surface 204, and in the overturning process of the rotating seat 200, the contact between the pushing surface 204 and the arc surface 512 gradually transits to contact with the bottom end of the pushing portion 511, so that the pushing member 510 pushes the rotating seat 200 to overturn more smoothly.
Further, referring to fig. 2 and 10, the inner top wall of the top case 110 is further extended with two supporting rib plates 112 downward, and both sides of the push part 511 are extended with supporting parts 513, and the supporting parts 513 are supported at the bottoms of the supporting rib plates 112. In this embodiment, after the push portion 511 pushes the rotary seat 200 to turn over, the reaction force of the rotary seat 200 to the push portion 511 causes the push portion 511 to form a tendency of yielding upwards, and the push portion 513 is supported at the bottom of the supporting rib plate 112 to support and limit the support portion 513, so as to support and limit the rotary seat 200 and the comb 300, and to avoid the problem of up-down movement of the comb 300 when the comb 300 is used for processing hair.
Still further, referring to fig. 10, a guide groove 113 is formed between the two support rib plates 112, and one end of the pushing member 510 near the push portion 511 is slidably retained in the guide groove 113.

The comb plate 600 is provided with a pressing surface 601, and the pressing surface 601 is an inclined surface facing the rotary seat 200. The inner side of the push-push part 511 is also provided with a pressing surface 514, the push-pull part 520 is pushed forward to enable the push part 510 to move forward, the push-push part 511 pushes the rotary seat 200 to turn over to enable the comb 300 to extend out of the mounting cavity 101 in a turning manner, when the push-pull part 520 is pulled backward, the push part 510 moves backward, the pressing surface 514 of the push-push part 511 contacts with the pressing surface 601 and pushes the comb plate 600 to move downward along the guide part 700, and the comb teeth extend out of the mounting cavity 101. In the present embodiment, when hair is treated using the comb 300, the push-pull member 520 is pushed forward to move the push member 510 forward, and the push-push part 511 pushes the rotary base 200 to be turned over, so that the comb 300 is protruded out of the mounting cavity 101 in a turned over manner, and thus hair can be treated using the comb 300. After the comb blade 300 is used to comb hair, the teeth 610 may be used to comb down hair and the residual hair on the pet body is combed down. Specifically, after the comb 300 is used to treat hair, the push-pull member 520 is pulled backward, the push member 510 moves backward, the pressing surface 514 of the push portion 511 contacts with the pressing surface 601, and since the pressing surface 514 of the push portion 511 is translated, the height between the pressing surface 514 and the bottom wall 103 of the mounting cavity 101 is kept constant, and the pressing surface 601 is an inclined surface, the pressing surface 601 is pushed by the pressing surface 514, so that the comb plate 600 moves downward against the elastic force of the supporting spring 800, and the comb teeth 610 extend out of the housing 100 through the clearance through holes 107, and the comb teeth 610 can be used to comb hair. After combing the hair, the pushing member 510 is pushed forward by the push-pull member 520 to reset, and the pressing surface 514 is separated from the pressing surface 601, so that the comb plate 600 moves upward under the elasticity of the supporting spring 800, and the comb teeth 610 are retracted into the housing 100, and the hair adsorbed on the comb teeth 610 is limited by the ribs between the clearance through holes 107, so that the hair is prevented from entering the housing 100.
Further, referring to fig. 8 and 9, the push part 511 is located at the free end of the push member 510 and is suspended, and the pressing surface 514 is located at the front side of the pressing surface 601, and the push member 510 is pulled backward, so that the pressing surface 514 presses the pressing surface 601 downward, so that the comb plate 600 moves downward. In this embodiment, since the push portion 511 is disposed obliquely downward, and the push portion 511 is located at the free end of the push member 510, the push portion 511 is pulled backward by pulling the push member 510 backward to press the comb plate 600, so that the push portion 511 forms a tendency to deform upward under the reaction force of the comb plate 600, and the push member 510 can be ensured to move continuously against the resistance of the comb plate 600 under the sufficient backward pulling force of the push member 510, so that the pushing surface 514 of the push portion 511 can press the comb plate 600 downward, and the comb plate 600 can be displaced downward smoothly.
Further, referring to fig. 4 to 9, bosses 620 extend upward from both ends of the top of the comb plate 600, pressing surfaces 601 extend from the upper ends of the bosses 620 to the bottom of the comb plate 600, and pressing portions 511 extend to both sides and to the front side of the bosses 620. In this embodiment, the two sides of the pushing portion 511 extend to the front side of the boss 620, so when the pressing surface 514 contacts with the pressing surface 601, the left and right ends of the comb plate 600 can both receive the pressing force of the pressing surface 514, which increases the area of the pressing surface 601 under force, further increases the stability of the pressing surface 601 after force is applied, and the problem that the comb plate 600 is blocked due to unbalanced force. In addition, the boss 620 is provided on the comb plate 600, so that the height of the pressing surface 601 can be increased, and thus the stroke of pressing down the comb plate 600 can be increased. And after the bottom end of the push-push part 511 slides to the top end of the pressing surface 601, the pushing member 510 will continue to move a small distance, so that the push-push part 511 is limited at the top of the boss 620, and the limiting effect on the comb plate 600 is achieved, and when the comb teeth 610 comb hair, an operator is not required to press the push-pull member 520, so that the practicality of the operator is more convenient.
Further, referring to fig. 4 to 9, a supporting table 630 extends upward from the top of the comb plate 600, a plurality of limiting rib plates 515 extend from the inner side of the pushing portion 511, and a limiting portion 516 is formed at the bottom end of the limiting rib plates 515 and is used for limiting the top of the supporting table 630. When the pushing member 510 moves backward and pushes the comb plate 600 downward and the top surface of the supporting table 630 is lower than the limit rib plate 515, the supporting table 630 is supported at the bottom end of the limit rib plate 515. In this embodiment, when the pushing portion 511 pushes the comb plate 600 to descend to the bottommost end, after the pushing member 510 continues to move backward for a certain distance, the top of the supporting table 630 slides to the bottom of the limiting rib plate 515, so that the limiting rib plate 515 limits the supporting table 630, and the comb plate 600 is prevented from being reset upwards. In addition, two bosses 620 of the comb plate 600 are limited by two ends of the push part 511, and the supporting table 630 is limited by the limiting rib plates 515, so that the comb plate 600 has three limiting points, the comb plate 600 can be stressed and balanced, and the problem that deflection occurs due to uneven stress of the comb plate 600 when the comb teeth 610 comb hair is avoided.
Further, a clearance slope 631 is provided on a side of the support base 630 adjacent to the push portion 511. The clearance bevel 631 enables the support table 630 to have a trapezoidal table structure, and increases the strength of the support table 630. In addition, the clearance inclined plane 631 can avoid the limit rib plate 515, so as to avoid the forced contact between the limit rib plate and the limit rib plate.

In this embodiment, when the pressing surface 601 of the comb plate 600 receives the horizontal pushing force of the pushing portion 511, the pushing portion 511 acts on the pressing surface 601, and the pressing surface 601 is an inclined surface and forms an angle of not 0 ° and not 90 ° with the movement direction of the pushing portion 511. Therefore, when the pressing surface 601 receives the force of the pressing surface 514, the pressing surface 601 receives downward pressure and flat thrust, under the action of the downward pressure, the comb plate 600 moves downward along the guide post 710, the flat thrust acts on the radial direction of the guide post 710 through the comb plate 600, so that the hole wall of the connecting hole of the comb plate 600 and the guide post 710 is tightly attached to the side wall of the guide post 710, and by arranging the guide rib plate 720 and the track groove 602 in clearance fit, the side wall of the track groove 602 is attached to the side wall of the guide rib plate 720, the guide contact area of the comb plate 600 is increased, and the guide contact area of the comb plate 600 is increased by a certain extrusion force, so that the comb plate 600 is prevented from tilting downward due to the supporting force of the supporting spring 800, the comb plate 600 is ensured to slide up and down along the guide piece 700, and the problem of blocking is avoided.
Further, referring to fig. 7, the lower end of the pressing surface 601 is not higher than the top end of the rail groove 602. Guide posts 710 attached to both ends of the comb plate 600 and rail grooves 602 are provided near the pressing surface 601. In this embodiment, when the pressing surface 514 contacts with the lower end of the pressing surface 601 and pushes the pressing surface 601 to move downward, since the lower end of the pressing surface is not higher than the top end of the rail groove 602, the problem of backward tilting of the comb plate 600 can be avoided when the comb plate 600 is pressed by the pressing portion 511, and the guide posts 710 at both ends of the comb plate 600 and the rail groove 602 are disposed close to the pressing surface 601, so that the inner side surface of the rail groove 602 can be better attached to the guide rib 720 and slide downward along the guide rib 720 and the guide posts 710.
Further, referring to fig. 7, the push portion 511 is located at the front side of the pressing surface 601, and when the push portion 511 does not contact the pressing surface 601, the bottom end of the pressing surface 514 is lower than the bottom end of the pressing surface 601, and the top end of the pressing surface 514 is higher than the bottom end of the pressing surface 601 and not higher than the top surface of the comb plate 600. In this embodiment, when the pressing surface 514 contacts with the pressing surface 601, the pressing surface is contacted with the lower end of the pressing surface 601 and pressed, and in the process of gradually lowering the comb plate 600, the lower end of the pressing surface 514 gradually contacts with the pressing surface 601 and gradually contacts with the upper end of the pressing surface 601, so that the stress point of the comb plate 600 gradually moves from the lower end to the upper end of the comb plate 600, further avoiding the problem that the comb plate 600 tilts backward, and making the downward movement of the comb plate 600 smoother.
Further, referring to fig. 10, two limiting plates 115 are disposed in the top case 110, the two limiting plates 115 form a slideway 111, and the pushing member 510 is slidably connected between the two limiting plates 115. Three clamping grooves 517 are also provided on both sides of the pusher 510. The inner sides of the two limiting plates 115 are provided with convex ribs 116 for limiting in the corresponding clamping grooves. In the present embodiment, when the pusher 510 pushes forward to extend the comb 300 from the housing 100, the ribs 116 are caught in the catching grooves 517 located at the rear side. When the comb 300 and the comb teeth 610 are retracted into the housing 100, the ribs 116 slide into the catching grooves 517 located at the intermediate position. When the pushing member 510 pushes the comb plate 600 to press down, the ribs 116 will be locked in the slots 517 on the front side, so that the pushing member 510 can play a certain limiting role when the pushing member 510 is located at different positions.
Further, referring to fig. 13, the rear side of the rotary base 200 is provided with mounting grooves 210 corresponding to the number of the chasers 300, the mounting grooves 210 and the bottom of the rotary base 200 form a clamping portion 211, one side of the chasers 300 is provided with a notch 302, the notch 302 forms an insertion portion 303 at the upper end of the chasers 300, the insertion portion 303 is inserted into the mounting groove 210, and the clamping portion 211 is clamped into the notch 302. The back side of the rotary seat 200 is also connected with a pressing plate 220, the pressing plate 220 is connected with the rotary seat 200 through a locking screw, and the pressing plate 220 presses the inserting part 303 in the mounting groove 210, so that the comb blade 300 is detachably mounted on the rotary seat 200, and the comb blade is convenient to mount and can be replaced.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
