Description

A kind of extension type spanner
Technical field
The utility model relates to a kind of spanner, and specifically a kind of extension type spanner, belongs to machine tool technical field.
Background technology
Spanner is a kind of conventional installation and removal instrument.Spanner is a kind of utilize lever principle to twist hand-operated tools that bolt, nut and other screw threads tightly hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
In production and life, the structure of widely used spanner is all generally fixing at present, cannot change moment, and being not easy to carry, being unfavorable for increasing work efficiency by regulating the length of pinch bar.Therefore in the urgent need to inventing a kind of spanner of telescopic handle.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of structure simple, easy to use, and can change the extension type spanner of moment by regulating the length of pinch bar.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of extension type spanner, comprise handle, spring, slide block, screw rod, adjusting nut, driving end, chamfering, it is characterized in that: in described handle, be provided with hollow structure, spring is provided with in handle, slide block and screw rod, one end of spring is fixedly connected with the bottom of the hollow structure be arranged in handle, the other end of spring is fixedly connected with one end of slide block, the other end of slide block is fixedly connected with one end of screw rod, screw rod is provided with adjusting nut, the other end of screw rod is fixedly connected with driving end, driving end is provided with chamfering.
The length of described handle is greater than the length of described screw rod.
The length of described screw rod is greater than the drift of described spring.
The length of described handle is greater than the length of described slide block.
Described driving end is provided with chamfering, and effect conveniently bolt or nut is inserted in driving end.
Described slide block is fixedly connected with screw rod and enters after in handle, and slide block and screw rod are fixed in handle by spring.
The surface of described handle, spring, slide block, screw rod, adjusting nut, driving end is through concentrated sulfuric acid Passivation Treatment, and object improves the resistance to corrosion of spanner, to adapt to the severe working environment of various complexity.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, and can change moment by regulating the length of pinch bar, is conducive to increasing work efficiency.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is stereochemical structure exploded perspective view of the present utility model.
In figure: 1-handle, 2-spring, 3-slide block, 4-screw rod, 5-adjusting nut, 6-driving end, 7-chamfering.
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 extension type spanner, comprise handle 1, spring 2, slide block 3, screw rod 4, adjusting nut 5, driving end 6, chamfering 7, it is characterized in that: in described handle 1, be provided with hollow structure, spring 2 is provided with in handle 1, slide block 3 and screw rod 4, one end of spring 2 is fixedly connected with the bottom of the hollow structure be arranged in handle 1, the other end of spring 2 is fixedly connected with one end of slide block 3, the other end of slide block 3 is fixedly connected with one end of screw rod 4, screw rod 4 is provided with adjusting nut 5, the other end of screw rod 4 is fixedly connected with driving end 6, driving end 6 is provided with chamfering 7.
The length of described handle 1 is greater than the length of described screw rod 4.
The length of described screw rod 4 is greater than the drift of described spring 2.
The length of described handle 1 is greater than the length of described slide block 3.
Described driving end 6 is provided with chamfering 7, and effect conveniently bolt or nut is inserted in driving end 6.
Described slide block 3 is fixedly connected with screw rod 4 and enters after in handle 1, and slide block 3 and screw rod 4 are fixed in handle 1 by spring 2.
The surface of described handle 1, spring 2, slide block 3, screw rod 4, adjusting nut 5, driving end 6 is through concentrated sulfuric acid Passivation Treatment, and object improves the resistance to corrosion of spanner, to adapt to the severe working environment of various complexity.
In time needing the length regulating pinch bar 1, manual turn adjusting nut 5 screws out screw rod 4 in handle 1, or screws in handle 1 by screw rod 4, can reach the object of the length regulating pinch bar 1.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from 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.
