Description

   Ratchet wrench structure   

The present invention relates to a ratchet wrench structure, in particular to a latching part of the control unit of the ratchet wrench structure, provided with a third projection, the third projection must be exposed outside the dial, Avoid the lack of excessive rotation of the dial in the third volume. A first protrusion is convexly provided at the two ends of the concave arc groove of the tooth, so that the card component is restricted by the two first protrusions when the card is displaced, and the dial of the control unit is in the third receiving groove. There is an angle limitation when rotating internally to avoid the lack of excessive rotation.

According to my previous knowledge, the conventional ratchet wrench structure, such as the US patent case number: US7121170B2, Taiwan patent case application number: 093200216, certificate number: M254305, patent name: ratchet wrench position structure, its patent structure is: Positioning structure of ratchet wrench. The ratchet wrench is mainly attached to the end of a handle 50 and has a larger head 51. The head 51 can accommodate a tool head 60 and a ratchet block 65, and a ratchet block. The 65 is actuated by a dial structure of the dial 70. It is characterized in that the dial 70 of the dial structure is formed with a through groove 71 corresponding to the ratchet 65, and a through groove 71 of the dial 70 is provided with a A positioning piece 75 for abutting the ratchet block 65 is formed with two upper and lower corresponding cutouts 76 in the center of the rear section of the positioning piece 75, and a guide piece 77 is formed between the two cutouts 76, so that the positioning piece 75 can use the The guide piece 77 is sheathed with a top support spring 78, so that the positioning piece 75 can be stably supported on the ratchet block 65; thereby, a set of a ratchet wrench can be smoothly dialed and positioned accurately.

However, the lack of the conventional ratchet wrench structure lies in:

1. Please supplement the fifth and sixth figures of the bulletin. The total length of the positioning piece 75 is usually smaller than the diameter outside the dial 70. Many users will hold the dial 70 and rotate the tool head. 60 to test the rattling sound of the ratchet block 65. The positioning piece 75 may be pressed by the ratchet block 65 and pressed against the top support spring 78. The positioning piece 75 will be completely submerged into the dial in an instant. In the block 70, as shown in the twenty-third figure, the twenty-third figure is a cross-sectional view drawn with the ratchet wrench structure of the US patent number US7121170B2, that is, the end of the positioning piece 75 does not protrude to the ratchet block. At the receiving groove 53, the positioning piece 75 will be hidden inside the dial 70, so that the positioning piece 75 can be rotated 360 degrees with the dial 70 in the dial receiving groove 54. There is a lack of excessive rotation of the shifting block 70 in the shifting block receiving groove 54.

2. In the state of excessive rotation in the twenty-third figure, if the user rotates the dial 70 clockwise, the dial 70 and the positioning piece 75 can be returned, and the ratchet wrench structure can still be used. However, some users will continue to turn the toggle 70 counterclockwise. When turning to the angle of the twenty-fourth figure, the twenty-fourth figure is a cross-sectional view of a ratchet wrench, the ratchet 65 and the ratchet groove. There is a gap between 53. The positioning piece 75 is springed to the gap by the elastic force of the top support spring 78. The ratchet block 65 and the positioning piece 75 are simultaneously accommodated in the ratchet block groove 53. The ratchet wrench structure It can no longer be used.

Another conventional ratchet wrench structure is the pre-patent filed by the applicant. Taiwan patent application number: 102138595, certificate number: I511847, patent name: ratchet wrench structure, please supplement the third figure to the first bulletin As shown in the five figures, the outside diameter of the dial 41 of the control unit 40 is larger than the total length of the card-making member 42, and also has the same defects as the same US patent US7121170B2.

In view of the lack of the above-mentioned conventional ratchet wrench structure, the inventor finally came to the market with a ratchet wrench structure that can solve the shortcomings of the conventional industry by leveraging years of manufacturing, production and design experience in related industries.

The conventional ratchet wrench structure has a lack of excessive rotation. The present invention relates to a ratchet wrench structure, and particularly to a latching piece of the control unit of the ratchet wrench structure provided with a third projection, the third projection It must be exposed outside the dial, so as to avoid the lack of excessive rotation of the dial in the third receptacle. A first protrusion is convexly provided at the two ends of the concave arc groove of the tooth, so that the card component is restricted by the two first protrusions when the card is displaced, and the dial of the control unit is in the third receiving groove. There is an angle limitation when rotating internally to avoid the lack of excessive rotation.

The invention relates to a ratchet wrench structure, which comprises: a system provided with a first receiving slot, a second receiving slot and a third receiving slot; a ratcheting system pivotally arranged in the first receiving slot; a tooth system The tooth is accommodated in one side of the second receiving groove and can be displaced left and right in the second receiving groove. A concave arc groove is provided on the rear side of the tooth making, and a receiving groove is provided on at least one end of the tooth making. A first convex block is protruded at each of the two ends of the groove; a control unit includes: a toggle button, a card piece and an elastic element; the toggle button is provided with a cylindrical block, and the cylindrical block is pivotally arranged on the third In the receiving slot, the cylindrical block is provided with a first receiving slot and a second receiving slot; the card-making member is received at the first receiving slot, and the card-making member is provided with a third receiving section. A third protrusion is attached to one end of the card piece, the third protrusion is exposed outside the first accommodation groove, the third protrusion is received at the accommodation groove, and the third The protruding block can be displaced left and right at the receiving slot; the elastic element is received in the second receiving slot and the third receiving slot, and the card piece is resisted by the elastic force of the elastic element. The toothed arc of the recessed groove.

The card component of the control unit is provided with a third projection, and the third projection must be exposed outside the first receiving slot of the dial, so as to avoid that the dial may be in the third There is a lack of over-rotation of 360 degrees in the tank. The control unit is pivotally disposed in the third receiving groove of the body, and a first projection is convexly arranged at the two ends of the concave arc groove. When the turning part is turned to switch the positive and negative rotation of the ratchet wrench structure, The card-making part is driven to move within the range of the concave arc groove of the tooth by the button, and the two first bumps are convexly arranged at the two ends of the concave arc groove, so that the card The displacement of the workpiece at the concave arc groove is limited by the two first bumps. The knob of the control unit has an angle limitation when rotating in the third groove, so as to avoid the lack of excessive rotation.

In order to fully understand the effects of the present invention by members of the Bureau and those skilled in the art, the structure and composition of the present invention are explained in conjunction with the drawings and figures, but the following are only used to explain the implementation of the present invention. For example, it is not intended to limit the present invention in any form, and any modification made under the spirit of the present invention should still fall within the protection scope of the present invention.
