The advantage of the utility model ratchet wrench structure is:

1. The restricting groove 72 is provided for the first restricting part 53, so the gear 50 does not need to be provided with any groove structure, and the gear 50 can have a certain torque without breaking the structure, and the gear 50 is compatible with the existing gears same.

2. The area of the limiting groove 72 is larger than that of the first limiting portion 53, so that when the gear 50 is retracted, the first limiting portion 53 will be displaced in the limiting groove 72, and the second control member 70 will not be displaced.

3. The second abutment surface 71 abuts against the first abutment surface 161, so that the second control member 70 does not come out of the fifth container 15, and the tooth 50 is restricted by the second restricting part 73 and does not come out of the second container 12. place.

4. When the toothing 50 is retracted, the third top surface 511 is still against the first top surface 24, the fourth top surface 512 is still against the second top surface 32, and the ratchet 20 is still pivoted on the first container. Groove 11.

5. When the control part 70 is displaced at the fourth container 14 and the fifth container 15, the second restricting part 73 can drive the first restricting part 53 and the gear 50 to shift, so that the engaging part 51 and the ratchet part 21 are aligned. disengage, and the third top surface 511 is not against the first top surface 24, and the fourth top surface 512 is not against the second top surface 32, the ratchet 20, the ring 30 and the buckle 40 can be released from the first top surface. Remove the container at 11.

6. Supplemented with points 2 and 5, when the gear 50 is withdrawn, the second control member 70 will not shift, but the control member 70 will drive the gear 50 when it is displaced at the fifth container 15. The second container 12 is displaced.

7. After the second control member 70 and the gear 50 are moved back, the ratchet 20, ring 30 and clasp 40 can be removed from the upper or lower end of the first container 11, and the removal of the ratchet 20 does not need to be directional.

Therefore, the ratchet wrench structure of the utility model has industrial applicability, novelty and progress, can meet the application requirements of a utility model patent, and an application is filed according to law.
