Abstract

The utility model relates to an automatic telescopic socket wrench comprising a handle, a connection rod, a telescopic rod, a chamfer, a socket head, a spring, a latch, a latch hole and guide rails. The automatic telescopic socket wrench is characterized in that two sides of the connection rod are respectively provided with the guide rail; and the length of the connection rod is larger than the length of the guide rails. The automatic telescopic socket wrench is simply structured with convenient use; the length of the connection rod of the socket wrench can be adjusted in a large range, so a bolt or a nut in different depths can be detached and fastened and the number of socket wrenches needed carrying by personnel is reduced; and by the use of the automatic telescopic socket wrench, labor intensity of personnel is reduced and work efficiency is improved.

Description

A kind of automatic telescopic box spanner
Technical field
The utility model relates to a kind of spanner, and specifically a kind of automatic telescopic box spanner, belongs to machine tool technical field.
Background technology
In machine work, often need to use box spanner to dismantle with fastening bolt or nut.In producing and living, the length of widely used box spanner connecting rod is generally all fixed at present, cannot dismantle and fastening bolt or nut in different depth position, the box spanner that often needs personnel to carry multiple different length specification just can complete dismounting and fastening bolt in different depth position or the task of nut, so not only increase use cost, and increase personnel's labour intensity, be unfavorable for increasing work efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to use, and the adjustable automatic telescopic box spanner of length of connecting rod.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of automatic telescopic box spanner, comprise handle, connecting rod, expansion link, chamfering, collet head, spring, latch, pin hole, guide rail, vertical being fixedly connected with in middle part of described connecting rod and handle, in connecting rod, be provided with expansion link and spring, expansion link under the elastic force effect of spring all the time in maximum elongation state, the length of connecting rod is greater than the length of expansion link, the both sides of connecting rod are provided with guide rail, expansion link is provided with pin hole, the end of expansion link is provided with chamfering, expansion link is connected with collet head, in pin hole, be provided with latch.
The length of described connecting rod is greater than the length of described guide rail.
In described pin hole, be provided with latch, object is to coordinate guide rail prevent that expansion link is loosening or come off.
The end of described expansion link is provided with chamfering, and object is to facilitate expansion link to be connected with collet head.
The drift of described spring is greater than the length of described connecting rod.
The utlity model has following beneficial effect: simple in structure, easy to use, the length of regulating sleeve spanner connecting rod in a big way, thereby can dismantle and fastening bolt or nut in different depth position, effectively reduce the quantity of the required box spanners that carry of personnel, not only can reduce use cost, and can reduce personnel's labour intensity, be conducive to increase work efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structure exploded perspective view of the present utility model.
In figure: 1-handle, 2-connecting rod, 3-expansion link, 4-chamfering, 5-collet head, 6-spring, 7-latch, 8-pin hole, 9-guide rail.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of automatic telescopic box spanner, comprise handle 1, connecting rod 2, expansion link 3, chamfering 4, collet head 5, spring 6, latch 7, pin hole 8, guide rail 9, vertical being fixedly connected with in middle part of described connecting rod 2 and handle 1, in connecting rod 2, be provided with expansion link 3 and spring 6, expansion link 3 under the elastic force effect of spring 6 all the time in maximum elongation state, the length of connecting rod 2 is greater than the length of expansion link 3, the both sides of connecting rod 2 are provided with guide rail 9, expansion link 3 is provided with pin hole 8, the end of expansion link 3 is provided with chamfering 4, expansion link 3 is connected with collet head 5, in pin hole 8, be provided with latch 7.
Described expansion link 3 under the elastic force effect of described spring 6 all the time in maximum elongation state.
The length of described connecting rod 2 is greater than the length of described expansion link 3.
The length of described connecting rod 2 is greater than the length of described guide rail 9.
In described pin hole 8, be provided with latch 7, object is to coordinate guide rail 9 prevent that expansion link 3 is loosening or come off.
The end of described expansion link 3 is provided with chamfering 4, and object is to facilitate expansion link 3 to be connected with collet head 5.
The drift of described spring 6 is greater than the length of described connecting rod 2.
In the time of needs dismountings and fastening bolt in putting compared with deep-seated or nut, directly collet head 5 is aimed at need to be disassembled and fastening bolt or nut turning handle 1 detachably with fastening bolt or nut in putting compared with deep-seated.
In the time of needs dismountings and fastening bolt in more shallow position or nut, first collet head 5 is aimed at and need to be disassembled and fastening bolt or nut, then continu to press enters expansion link 3 compressions in connecting rod 2, and i.e. detachable and fastening bolt or the nut in more shallow position of turning handle 1.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
