Description

Wrench structure

The invention relates to a wrench structure, in particular to a wrench structure, the first ring system is coupled to the first end portion, so that the sliding groove is closed, and the clamping member is displaced against the On the first ring body, the rod system is limited by the clamping member and the first ring body and cannot completely escape the second body.

As previously known by us, the conventional wrench structure, such as the Taiwan Patent Application No.: 102206348, certificate number: M459080, patent name: the spanless telescopic structure of the wrench body, the patent structure is: a wrench body The segment telescopic structure mainly includes a wrench body 10 which is provided with a wrench rod 11 , and a wrench head 12 is coupled to the front end of the wrench rod 11 , and a ring groove 13 is dug in the rear portion of the wrench rod 11 . The ring groove 13 is sleeved with a rubber ring 14 and is disposed on the wrench rod 11 at the front end of the ring groove 13, and is provided with a slot 15 and a resilient member 16 and a cylinder 17 are built in the slot 15; The shank 20 is sleeved on the rear end of the wrench shaft 11. The hand shank 20 has a hollow portion 21 extending inwardly from the front sleeve hole 22, and the hollow portion 21 is dug on the inner wall of the sleeve 22. a ring groove 23, the ring groove 23 is provided with a rubber ring 24, and is located on the inner wall of the hollow portion 21 at the rear end of the ring groove 23, and a slope groove 25 is additionally dug; the wrench rod 11 is When the hand grip 20 moves, if the cylinder 17 of the wrench rod 11 moves to the hand grip 20 Ramp groove 25, the cylinder 17 will be pushed outward by the elastic member 16 and the card 25 against the ramp grooves When the wrench rod 11 moves in the handle sleeve 20, the rear end of the wrench rod 11 and the rubber ring 24 in the front end ring groove 23 of the hollow portion 21 will simultaneously abut against the inner wall of the wrench rod 11 and the hollow portion 21. The structural state of the frictional positioning is generated, which is characterized by it.

However, the missing structure of this conventional wrench is:

1. As shown in the second figure of the bulletin, the hand-held shank 20 is provided with a slope groove 25 on the inner wall of the hollow portion 21 at the rear end of the ring groove 23, when the wrench rod 11 is in the hand-held sleeve. When the handle 20 moves, if the cylinder 17 of the wrench rod 11 moves to the slope groove 25 of the hand grip handle 20, the cylinder 17 is pushed outward by the elastic member 16 and is pressed against the slope groove 25 However, the slope groove 25 is disposed at the inner circumferential surface, and the slope groove 25 is not easy to process in the process, that is, the production cost is easily increased.

2. The elastic member 16 may be elastically fatigued due to long-term use. If the elastic force of the elastic member 16 fails, the elastic member 16 cannot push the cylindrical body 17 outward, so that the cylindrical body 17 cannot be stuck. On the slope groove 25, the wrench rod 11 and the hand-held sleeve 20 are disengaged when they are stretched and stretched.

In view of the lack of the above-mentioned conventional wrench structure, the creator has been engaged in the manufacturing, production and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the wrench structure.

A new type of problem to be solved: in the structure of the wrench, the slope groove is disposed at the inner circumferential surface, and the slope groove is not easy to process on the process, that is, the cost of production is easily increased, and the wrench structure of the present invention The first ring system is coupled to the first end portion such that the slip groove is Closed, the clamping member is displaced against the first ring body, and the rod system is limited by the clamping member and the first ring body and cannot completely escape the second body, thus having Better limiting efficacy.

Technical solution for solving the problem: a wrench structure, comprising: a wrench set comprising a first body; the first system is provided with a rod body, a sliding groove and a first end; a second system is provided The fourth pocket is provided for the rod body to be compatible, the rod system is slidable in the fourth tank, the second system is provided with a first perforation and a bead groove; Between the slip groove and the bead groove, the clamping member is displaced on the sliding groove to displace the rod system in the fourth receiving groove to adjust the total length between the wrench set and the second body a first ring system is coupled to the first end portion, the first ring system makes the sliding groove closed, and when the rod is displaced in the fourth receiving groove, the clamping member is displaced The first ring system is provided with a ring groove by being restrained by the first ring body so that the rod system is restricted by the clamping member and the first ring body and cannot completely escape the fourth receiving groove; a second ring system is disposed at the annular groove and is slightly elastic, and the second ring system is disposed at an inner circumferential surface of the fourth receiving groove to make the second body opposite to the wrench set Having a sliding resistance of the second ring of the time shift.

According to the effect of the prior art, the second ring system abuts the inner circumferential surface of the fourth cavity of the second body, so that the second body has the sliding resistance of the second ring body when sliding relative to the wrench set. The set of the wrench and the second body can have the positioning effect of each position by the resistance of the second ring body. The card member is disposed in the ball-receiving groove, and the wrench body is assembled with the second body and the clamping member, the rod system is received in the fourth receiving groove and is applicable to the fourth The displacement in the cavity allows the card member to be displaced on the sliding groove to adjust the total length between the wrench set and the second body. The first ring system is coupled to the first end portion to make the sliding groove closed. The clamping member is displaced against the first ring body, and the rod system is limited by the clamping member and the first ring body and cannot completely escape the fourth receiving groove, thereby having a limiting effect. When the rod body is displaced to abut the first ring body, the wrench body and the second body are the longest length.

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.
