Ratchet wrench structure

The present invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure 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 is provided with a driving portion, and the driving portion is connected with a holding portion. The driving portion is provided with a first receiving portion and a second receiving portion that is tangent to the first receiving portion. The top edge of the second receiving portion of the body is open to the air; a ratchet member is rotatably disposed in the first receiving portion of the body, and the side wall ring of the outer edge of the ratchet member is provided with teeth; The two latching members are respectively slidably disposed at two ends of the second receiving portion of the body, and the two latching members are provided with teeth on one side of the ratchet member, and the two latching members are provided with teeth. The top surface of the opposite end of the piece is respectively provided with a guiding portion, and an elastic body is disposed between the two clamping members; a reversing member, one end of the reversing member is pivotally disposed at one end of the ratchet member, and the reversing member is another The end cover is coupled to the second receiving portion of the body to close the second receiving portion, and the other end of the rotating member is provided A portion corresponding to the steering of the two guide portions of the two latches, the control portion to selectively toggle member engaging portion of the guide, the teeth engaging member separated from the ratchet teeth of the movable member.

But the missing structure of this custom structure is:

1. As shown in the cross-sectional view of the fourth figure of the U.S. Gazette, one end of the reversing member is pivotally disposed at one end of the ratchet member, that is, the ratchet member and the reversing member are pivotally connected, and the reversing member is further The guiding portion of the end control unit controls the latching member to rotate the reversing member to move the latching member, thereby controlling the engagement between the latching member and the ratchet member, but when the ratchet is engaged When the moving member rotates three hundred and sixty degrees, the pivoting member and the reversing member have a pivotal relationship, and the reversing member should be rotated to naturally switch to another clamping member to engage with the ratchet member, that is, There will be a lack of automatic commutation.

2. When the ratchet is rotated by three hundred and sixty degrees, the number of the reversing parts will be interlocked and the latching member will be slightly displaced, and the meshing state between the latching member and the ratchet member will be engaged. indeed.

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

The new problem to be solved: the conventional ratchet wrench has the automatic switching reverse reversal. This creation is related to the structure of a ratchet wrench, especially a ratchet wrench structure with a control member and a cover. A first control unit and a driving unit are disposed. The cover system is provided with a second control unit. The first control unit is movable with the second control unit, and the driving unit and the teeth are mutually activated.

Technical means for solving the problem: a ratchet wrench structure, comprising: 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 The system is pivoted in the first tank; the two teeth are placed on the left and right sides of the second tank, 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.

According to the prior art, 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 is compatible with the tooth making. By making a mutual card, the 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.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation. For example, it is not intended to impose any form of restriction on this creation. Any modification made in the spirit of this creation should still fall within the scope of this creation.
