Description

A kind of telescopic spanner

Technical field

The utility model is related to machine tool technical field, specially a kind of telescopic spanner.

Background technology

Spanner is a kind of conventional installation and extracting tool, and bolt, screw, nut and other spiral shells are twisted using lever principle Line tightly holds the opening or the hand tools of trepanning firmware of bolt or nut, and spanner is generally formed with clamping in the one or both ends of shank The opening or set hole of bolt or nut, threadingly direction of rotation applies external force in shank when using, with regard to that can twist bolt or nut. But, existing spanner, structure is excessively simple, most of to use straight panel vertical designs, it is impossible to arbitrarily adjusted according to the need for user Save torque arm length, narrow application range.

Utility model content

The purpose of this utility model is to provide a kind of telescopic spanner, can not with solve to propose in above-mentioned background technology According to the need for user the problem of any regulation torque arm length, narrow application range.

To achieve the above object, the utility model provides following technical scheme：A kind of telescopic spanner, including buckle, extension It is connected with the right side of ring, push rod and spring, the buckle on the right side of shell, and shell and is provided with dop, the enclosure is inlaid with It is provided with below slide rail, the link on the right side of handle, the push rod and is connected with the first sliding block, is fixed with the right side of first sliding block It is provided with the left of button, the spring on the left of retaining ring, the retaining ring and the second sliding block is installed, is set on the left of second sliding block It is equipped with the left of damped ring, the damped ring and is connected with wrenching bar, driving end is fixed with the left of the wrenching bar, the driving end is left Side is provided with lid.

It is preferred that, it is mounted on magnet arrangement inside the buckle and lid.

It is preferred that, the slide rail left end is provided with limited block.

It is preferred that, the grip surface is provided with sweat-absorbing layer.

It is preferred that, the lid is rotatable device, and rotation angle range is 0-180 degree.

Compared with prior art, the beneficial effects of the utility model are：The telescopic spanner, can be provided with the first sliding block Released when needs with finger, can be applied widely according to any regulation torque arm length the need for user, be inconvenient to use Also by pressing the button of lower tail driving end can be made slowly to stretch out when first sliding block, and store volume contracting after driving end It is small, saved space, retaining ring can after driving end is elongated to appropriate length locking wrench bar, it is to avoid slided when use It is dynamic, cause spanner to slide and produce unexpected, the handle place of setting is equipped with link, can without using when hang up, convenient for collecting.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

In figure：1- buckles, 2- shells, 3- slide rails, 4- dops, 5- links, 6- handles, 7- push rods, the sliding blocks of 8- first, 9- is pressed Button, 10- springs, 11- retaining rings, the sliding blocks of 12- second, 13- damped rings, 14- wrenching bars, 15- driving ends, 16- lids.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Referring to Fig. 1, a kind of telescopic spanner that the utility model is provided, including buckle 1, link 5, push rod 7 and spring 10, the right side of buckle 1, which is connected with inside shell 2, buckle 1 and lid 16, is mounted on magnet arrangement, it can be ensured that closed in lid 16 After will not unclamp easily, and the right side of shell 2 is provided with inside dop 4, shell 2 and is inlaid with slide rail 3, and the left end of slide rail 3 sets limited Position block, it is ensured that wrenching bar 14 will not be produced because of excessive slip to come off, the lower section of link 5 is provided with handle 6, and the surface of handle 6 is set Sweat-absorbing layer is equipped with, the right side of push rod 7 is connected with the first sliding block 8, and the right side of the first sliding block 8 is fixed with button 9, and the left side of spring 10 is provided with Retaining ring 11, the left side of retaining ring 11 is provided with the second sliding block 12, and left side is provided with damped ring 13, and the left side of damped ring 13, which is connected with, pulls Hand lever 14, the left side of wrenching bar 14 is fixed with driving end 15, and the left side of driving end 15 is provided with lid 16, and lid 16 is rotatable dress Put, and rotation angle range is 0~180 degree.

Operation principle：During using the telescopic spanner, retaining ring 11 is first unclamped, rotation dismounting lid 16, thumb pins the One sliding block 8 is simultaneously promoted forward, and push rod 7 promotes the second sliding block 12, and spring 10 shrinks, and the second sliding block 12 is promoted by wrenching bar 14 and pulled 15 stretch out at hand, after length needed for driving end 15 is extend out to, fixed retaining ring 11, or with the pressing button of finger stage 9, the number of times that driving end 15 can be pressed according to button 9 stretches out regular length；After the completion of use, retaining ring 11, spring 10 are unclamped Elongation, the second sliding block 12 is slow in the presence of spring 10 to withdraw wrenching bar 14, and then withdraws driving end 15, finally screws lid 16。
