The transmission mechanism comprises a gear capable of meshing with the saw teeth 223 of the handle 2. And the winding roll 7 is connected with the transmission mechanism and is used for winding the thread rope. The transmission mechanism is in one-way transmission, and is characterized in that: when the handle 2 is pressed, the gear of the transmission mechanism is meshed with the saw teeth 223 of the handle 2 for transmission, and the winding roll 7 is driven to rotate so as to wind the wire rope. When the handle 2 is reset, the transmission mechanism is disconnected with the transmission between the winding roll 7, and the winding roll 7 is still. When one-way transmission can avoid pressing 2 rolling cotton ropes of handle, handle 2 resets and leads to 7 reversals of take-up reel to loosen the condition of cotton rope, invalid rolling, also can avoid the cotton rope to appear in a jumble.

This scriber 100 improves the rolling mode through with hand formula for the push type rolling, consequently can accomplish the function of one-hand rolling cotton rope, liberates user's other hand, and the user can also do other things in the rolling cotton rope, and is more convenient.

The movable claw 43 is connected with the gear, the ratchet wheel 5 is coaxially connected with the winding roll 7, when the gear rotates along a first rotating direction, the ratchet wheel 5 is meshed with the movable claw 43, the movable claw 43 pushes the ratchet wheel 5 to rotate, and the ratchet wheel 5 drives the winding roll 7 to rotate synchronously. When the gear wheel rotates in the second direction of rotation, the ratchet wheel 5 disengages from the moveable jaw 43 and the ratchet wheel 5 and the take-up reel 7 are stationary. Wherein the second rotation direction is opposite to the first rotation direction.

In order to improve the winding efficiency, the transmission mechanism of the scriber 100 is also geared up to reduce the number of times the handle 2 is pressed. Specifically, drive mechanism includes engaged with first toothed disc 3 and second toothed disc 4, wherein, first toothed disc 3 with the sawtooth 223 of handle 2 meshes mutually, second toothed disc 4 is connected moveable claw 43, just the rotational speed of first toothed disc 3 is less than the rotational speed of second toothed disc 4. As a result, the moveable jaw 43 connected to the second toothed disc 4 obtains a higher rotational speed, so that the ratchet wheel 5 driven by the moveable jaw 43 can also obtain a higher rotational speed, which in turn increases the rotational speed of the spool 7 mounted on the ratchet wheel 5. Therefore, the scribing instrument 100 can rotate the spool 7 more times by pressing the handle 2 once, thereby winding the string more quickly.

Preferably, in the present embodiment, as shown in fig. 2 and 3, the first gear plate 3 includes a first gear 31 and a second gear 32 coaxially disposed, wherein the first gear 31 is engaged with the saw teeth 223 of the handle 2, and the number of teeth of the second gear 32 is greater than that of the first gear 31.

The second gear plate 4 includes a third gear 41, the third gear 41 is engaged with the second gear 32, and the number of teeth of the third gear 41 is smaller than that of the second gear 32.

In the scriber 100, the handle 2 is engaged with the first gear 31 to rotate the first gear plate 3, and the second gear 32 rotates with the first gear plate 3. The second gear 32 is in mesh transmission with the third gear 41, so that the second gear disc 4 is driven to rotate by the second gear 32. The second gear wheel 4 drives the movable claw 43 to rotate, and the movable claw 43 rotates to push the ratchet wheel 5 to rotate, so that the winding roll 7 finally rotates under the driving of the ratchet wheel 5. Because handle 2 and the meshing of the first gear 31 that the number of gears is less, consequently press handle 2 once and can make first toothed disc 3 rotate more number of turns, rethread second gear 32 on first toothed disc 3 and the meshing transmission of third gear 41 on the second toothed disc 4, because the number of teeth of third gear 41 is less than the number of teeth of second gear 32, make third gear 41 obtain bigger drive ratio, further improve the rotational angular velocity of second toothed disc 4, drive second toothed disc 4 and rotate more number of turns promptly, finally make take-up reel 7 rotate more number of turns, the longer cotton rope of rolling. In addition, the winding roll 77 can be continuously rotated for a plurality of turns by inertia after the handle 2 is pressed once, thereby reducing the number of pressing times. Through practice, this scriber 100 can improve rolling efficiency greatly, reduces and presses 2 times of handle, and a dish cotton rope only need press several times can all accomplish the rolling.

Preferably, in the present embodiment, the second gear plate 4 is disposed coaxially with the ratchet wheel 5, so that space can be saved. Specifically, the transmission mechanism of the scriber 100 further comprises a transmission disc 50, the transmission disc 50 is connected with the second gear disc 4 through a pivot 6, and the wire winding disc 7 is also mounted on the pivot 6. The driving plate 50 has a groove 51, the outer edge of the groove 51 has a plurality of teeth 510, and the outer contour of the plurality of teeth 510 of the groove 51 forms the ratchet wheel 5. Several teeth 510 spirally form the ratchet 5 in the same rotation direction. Wherein the direction of the spiral formed by the tooth part 510 is the same as the rotation direction of the movable jaw 43 when the handle 2 is pressed, so that the movable jaw 43 can push the ratchet wheel 5 to rotate. In the present embodiment, the tooth portion 510 forms the ratchet 5 in the counterclockwise direction as shown in fig. 7 and 8.

As shown in fig. 8, the second gear plate 4 further includes a mounting plate 42, the pivot shaft 6 penetrates the mounting plate 42 and the third gear 41, and the movable claws 43 are respectively disposed at both ends of the mounting plate 42. The movable claw 43 on the second gear wheel 4 is accommodated in the groove 51, and the movable claw 43 is engaged with the ratchet wheel 5 in a unidirectional way. When the movable claw 43 extends into the tooth part 510 of the groove 51, the movable claw can push the transmission disc 50 to rotate synchronously. However, when the movable claw 43 rotates in the opposite direction, the movable claw 43 exits from the tooth portion 510 of the groove 51, the movable claw 43 is separated from the transmission plate 50, and the movable claw 43 cannot drive the transmission plate 50 to rotate.

In particular, as shown in connection with fig. 7, each of said teeth 510 in the groove 51 in the transmission disc 50 has a first side 511 and a second side 512 forming a first angle a, the first angle a of said teeth 510 being not greater than 90 °. The first included angle a is used for receiving the driving member 43, so that the driving member 43 pushes against the first included angle a to drive the transmission disc 5 to rotate. The angle of the first included angle a is therefore not greater than 90 ° to facilitate the driving member 43 exerting a force on the driving disc 5. Each tooth portion 510 further has a third edge 513, and the third edge 513 is connected to the second edge 512 to form a second included angle B, which is an obtuse angle. The second included angle B is an obtuse angle, so that the driving part 43 can be conveniently separated from the first included angle a when the driving part rotates reversely. A third side 513 of said tooth 510 connects to a first side 511 of an adjacent said tooth 510 and forms a third angle C, said third angle C being not more than 90 °. The third included angle C determines the angle at which the tooth 510 drifts outwards, and the third included angle C is not greater than 90 °, so that the driving member 43 can be more easily thrown into the first included angle a by inertia when the second gear disc 4 rotates along the first rotation direction 81.

The working principle of the scribe 100 will be explained below:

when the handle 2 is pressed in the direction of the arrow shown in fig. 4, the handle 2 rotates around the mounting shaft, the saw teeth 221 of the handle 2 mesh with the first gear 31 on the first gear plate 3, and as the handle 2 is pressed deeper into the housing 1, the first gear 31 is driven to rotate, so that the first gear plate 3 rotates. The first gear plate 3 rotates to drive the second gear 32 to rotate. As shown in fig. 5, the second gear 32 rotates in the clockwise direction 81 to drive the third gear 41 engaged with the second gear 32 to rotate, so that the second gear plate 4 rotates in the counterclockwise direction 82. The movable claw 43 on the second gear wheel 4 rotates synchronously with the second gear wheel 4 and extends into one tooth 510 of the groove 51 of the transmission disc 50, so that the transmission disc 50 is driven to rotate. The transmission disc 50 drives the winding roll 7 connected with the transmission disc to rotate, and the effect of winding the thread rope is achieved.

In addition, the transmission mechanism in the scriber 100 improves the rolling efficiency through the speed increasing transmission of the handle 2, the first gear 31, the second gear 32 and the third gear 41, reduces the times of pressing the handle 2 and improves the feeling of a user.

After the handle 2 is pressed, the handle 2 is released, and the handle 2 is rotated in the reverse direction (in the arrow direction in fig. 6) to be reset under the action of the torsion spring 23, as shown in fig. 6. The first gear wheel 3 is rotated in the opposite direction, i.e. in the counter clockwise direction 83, by the handle 2. First toothed disc 3 drives second toothed disc 4 and rotates along clockwise 84 for movable claw 43 rotates clockwise 84 and withdraws from in the tooth portion 510 of the recess 51 of driving plate 50, movable claw 43 slips with driving plate 50 and can't drive driving plate 50 and rotate, consequently driving plate 50 also can't drive take-up reel 7 and rotate, so the good cotton rope of just rolling also can not loosen, prevent that take-up reel 7 from reversing and leading to invalid rolling, also avoid the cotton rope to be in disorder to tie a knot.

Repeated action of pressing handle 2 a few times can accomplish the cotton rope rolling as above, and is high-efficient, can also accomplish by the one hand, promotes user's use impression.

Preferably, the handle 2 of the scriber 100 further comprises a limiting block 24, and the limiting block 24 is installed in the housing 1. The stopper 24 abuts against the pressing portion 21 to limit the movable range of the handle 2 pressed up and down.
