Abstract

The utility model provides an elastic connecting device of a jack handle, which comprises a matching hole providing a locating pin shaft to be matched with a hole shaft is prearranged on the rear portion of the front section handle, a concave pit which allows an elastic metallic piece to traverse through and a through hole are arranged on the front portion of the front section handle, rivets which can rivet the front section handle and the elastic metallic piece are arranged on the front portion of the pit, a through-hole which can do the hole shaft moving match with the locking pin shaft of the elastic metallic pipe on the front section handle is arranged on the front portion of the rear section handle, and a boss which can press the locking pin shaft which is integrated with the boss to link and lock the front section and the rear section handles is arranged on the middle portion of the elastic metallic piece. Adopting the elastic connecting device of the proposal, the length of the jack handle can be conveniently combined to adapt to the lifting of different loading objects according to the operating needs, the joint is reliable, the use is convenient, the containing after finishing use is easy, the volume is small and the weight is light.

Description

The elastic connecting device of jack handle

Affiliated technical field

The utility model relates to a kind of operating handle of jack, especially relates to a kind of elastic connecting device that is used between the joint handle of jack front and back.

Background technology

Existing jack operation handle is made the many of single-unit long handle.Because for satisfying the vehicle of operator and jack jacking or the distance between the weight, generally do handle longer, this is being preserved cumbersome to jack and handle thereof with taking in after finishing, it is more inconvenient particularly to place with car, again, link to each other even some handle has been made several joints, but mechanical attachment of joint handle is also efficient and convenient inadequately before and after those.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of elastic connecting device that has is provided, and makes things convenient for the quick connection between the more piece handle, also is convenient to the collection after the handle use.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions: a kind of elastic connecting device of jack handle, comprise the prosthomere handle, the deutomerite handle, connecting link pin, it is characterized in that: the rear portion of prosthomere handle is preset with a place and makes the mating holes that the hole axle cooperates for the locking bearing pin, being provided with in its front portion can be for holding pit and the through hole that resilient metal member is passed through, and be provided with in the pit anterior position can be with the rivet of prosthomere handle and resilient metal member riveted joint, the front portion of deutomerite handle is provided with the through hole that can make hole axle running-fit with the locking bearing pin of resilient metal member on the prosthomere handle again, but be provided with at the middle part of resilient metal member pressing with it the locking bearing pin of one to connect the boss of joint handle before and after the locking.

The beneficial effect that the utility model compared with prior art has is: the elastic connecting device that adopts the jack handle of this case, can make up the length of jack handle easily to adapt to jacking according to action need to the different loads thing, joint is reliable, easy to use, with taking in easily after finishing, its volume is little, in light weight.

The specific embodiment

The utility model will be further described below in conjunction with the accompanying drawing of embodiment, will help the understanding to the utility model technology contents and effect.

In embodiment of the present utility model, the front end of prosthomere handle 1 is an open type hook 12, is used for and the articulating of jack power intake; Make the geometric configuration that can form moving sets 7 with the big mating holes of deutomerite handle leading section at the rear portion of prosthomere handle 1, be pressed into shape pit 9 in its cylindrical shell of column upper punch, and in pit 9, be preset with through hole 10 resilient metal member 3 to be provided to pass through and can make it up and down area of space; The locking bearing pin 6 of the head of resilient metal member 3 behind the through hole 10 that seals in pit 9, at first with prosthomere handle 1 body on mating holes 4 form the axis hole free-running fits, the face of joint 13 of the afterbody of resilient metal member 3 and prosthomere handle 1 are by rivet 8 riveted joints.

The elastic connecting device that this case handle is reliably extended is operated like this: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, press down the boss 11 of resilient metal member 3 with finger, but in the mating holes 4 of locking bearing pin 6 upper surfaces just retraction prosthomere handle 1, the mating holes that then left part of sensu lato prosthomere handle 1 is inserted deutomerite handle 2 forms moving sets 7, and make the mating holes 4 of prosthomere handle coaxial with the mating holes 5 of deutomerite handle 2, discharge the downforce on the boss 11 of resilient metal member 3, make it to lock that bearing pin 6 springs into mating holes 5 and realize that prosthomere handle 1 connects with the effective of deutomerite handle 2.Extending handle by with after finishing, press down the boss 11 on the resilient metal member 3, locking bearing pin 6 and mating holes 5 are broken away from after, promptly separable prosthomere handle and deutomerite handle, and do good collection.
