Description

Ratchet wrench structure

The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure, which is provided with a control member and a cover body, the control member is provided with a first control portion and a driving portion, and the cover system is provided with a second control portion, A control unit is operative with the second control unit, and the drive unit and the teeth are actuated with each other.

As previously known to us, the conventional ratchet wrench structure, such as U.S. Patent No. US7827886B2, and Taiwan Patent Application No.: 097131409, the patent name: a toggle type reversing ratchet wrench, a toggle type reversing ratchet wrench, The main body 10 is provided with a driving portion 11 . The driving portion 11 is connected to a holding portion 12 . The driving portion 11 is provided with a first receiving portion 13 and a tangent to the first receiving portion 13 . The second accommodating portion 14 is open to the top of the second accommodating portion 14 of the body 10; a swaying member 20 is rotatably disposed in the first accommodating portion 13 of the body The side wall ring of the outer edge of the ratchet member 20 is provided with teeth 22; the two latching members 30 are respectively slidably disposed at the two ends of the second receiving portion 14 of the body 10. The two latching members 30 are provided with teeth 22 on one side of the ratchet member 30. The top surfaces of the opposite ends of the two latching members 30 are respectively provided with a guiding portion 32, and an elasticity is provided between the two latching members 30. a reversing member 40, one end of the reversing member 40 is pivotally disposed at one end of the rocking member 30, and the other end of the reversing member 40 is closed to the second receiving portion of the body 10. The second accommodating portion 14 is closed, and the other end inner edge of the reversing member 40 is provided with a guiding portion 42 corresponding to the two guiding portions 32 of the two latching members 30, and the guiding portion 42 is selectable. The guiding portion 32 of the latching member is configured to separate the teeth 22 of the latching member 30 from the teeth 22 of the ratchet member 30.

But the missing structure of this custom structure is:

1. The auxiliary member 40 is pivotally disposed at one end of the ratchet member 20, that is, the ratchet member 20 and the reversing member 40 are pivotally connected, as shown in the cross-sectional view of the fourth section of the U.S.A. The other end of the reversing member 40 controls the guiding portion 32 of the latching member 30. When the reversing member 40 is rotated, the latching member 30 is rotated to control one of the latching members 30 and the ratchet member. 20 pieces are engaged or disengaged, but when the ratchet member 20 is rotated by three hundred and sixty degrees, the rocking member 20 and the reversing member 40 are pivotally connected to each other, and the reversing member 40 should be rotated to naturally switch. The other latching member 30 engages with the ratchet member 20, that is, the automatic commutation is lost.

2. When the ratchet member 20 is rotated by three hundred and sixty degrees, the number of the reversing member 40 is also interlocked to slightly shift the latching member 30, and the engaging state between the latching member 30 and the ratchet member 20 is That is, the meshing is not true.

In view of the lack of the structure of the ratchet wrench of the above-mentioned conventional patent case, the inventor has borrowed years of experience in related industries, and finally has a product that can solve the drawbacks of the ratchet wrench structure.

The conventional ratchet wrench has the function of automatically switching the reverse rotation. The present invention relates to a ratchet wrench structure, and particularly relates to a ratchet wrench structure which is provided with a control member and a cover body, and the control member is provided with a first control portion and In the driving unit, the cover system is provided with a second control unit, and the first control unit is movable with the second control unit, and the driving unit and the teeth are mutually activated.

A ratchet wrench structure includes: a system having a first receiving groove, a second receiving groove, a third receiving groove, a facing surface, a first ring groove and a fourth receiving groove; a ratchet system is pivoted at the first Inside the tank; two teeth are placed on the left and right sides of the second tank, the system The tooth system is provided with an end surface, a first convex portion and an abutting surface; an elastic member is disposed between the two teeth; a control member is pivotally disposed in the fourth receiving groove, and the control member is provided with the first control portion The first control unit is opposite to the first receiving portion, and a driving portion is disposed below the first control portion. The driving portion is provided with a driving surface on both sides thereof, and the driving surface is opposite to the abutting surface. The cover system is provided with abutting portion and is disposed at the third receiving groove. The abutting portion is provided with a second control portion, and the second control portion is interlocked with the first control portion, and the abutting portion is convexly disposed The ring portion is disposed on the first ring groove, and the ring portion is provided with a limiting surface that abuts against the abutting surface, and the cover system is received on the body by the ring portion and the limiting surface.

The control unit is provided with a first control unit and a driving unit. The first control unit is connected to the second control unit of the cover body, and the driving surface of the driving unit can be mutually engaged with the tooth-making surface. Move, and control is reversed. The driving portion of the control member is pressed against the end surface of one of the teeth, and the tooth forming system is restricted by the driving portion and is accommodated in the second receiving groove without being disengaged. In this case, the control member can be rotated first. It is smooth to drive the two teeth to be displaced to the left and right at the second pocket. The two tooth shifts can be tested without all the components being assembled, and the test is reversed first. When the user pushes the cover body to the left, the left side of the tooth is attached to the second groove wall surface to disengage the ratchet, and the left side tooth is moved by the elastic element to interlock the right side of the tooth. The right tooth and the ratchet portion mesh with each other, so that the ratchet wrench structure achieves a positive reversal effect.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
