Description
Technical field
The utility model relates to a kind of spanner, specifically a kind of telescopic wrench, 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 telescopic wrench 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 telescopic wrench, comprise handle, screw hole, trip bolt, Telescopic handle, draw-in groove, driving end, it is characterized in that: the top of described handle is provided with screw hole, trip bolt is provided with in screw hole, Telescopic handle is provided with in handle, the both sides of Telescopic handle are provided with draw-in groove, one end of Telescopic handle is fixedly connected with driving end, Telescopic handle enters after in handle, trip bolt is arranged in the draw-in groove of Telescopic handle both sides through embedding after the screw hole be arranged on handle, Telescopic handle is fixed in handle, hollow structure is provided with in handle, Telescopic handle passes through to slide in handle thus reaches the object of telescopic handle, the width of draw-in groove is greater than the diameter of the screw rod of trip bolt, the length of Telescopic handle is greater than the length of draw-in groove, one end of Telescopic handle is fixedly connected with driving end, the fastened screw of the other end of Telescopic handle is fixed in handle, handle, the surface of Telescopic handle and driving end is through concentrated sulfuric acid Passivation Treatment.
The length of described Telescopic handle is greater than the length of described handle.
The surface of described handle, Telescopic handle and 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-screw hole, 3-trip bolt, 4-Telescopic handle, 5-draw-in groove, 6-driving end.
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 telescopic wrench, comprise handle 1, screw hole 2, trip bolt 3, Telescopic handle 4, draw-in groove 5, driving end 6, it is characterized in that: the top of described handle 1 is provided with screw hole 2, trip bolt 3 is provided with in screw hole 2, Telescopic handle 4 is provided with in handle 1, the both sides of Telescopic handle 4 are provided with draw-in groove 5, one end of Telescopic handle 4 is fixedly connected with driving end 6, Telescopic handle 4 enters after in handle 1, trip bolt 3 is arranged in the draw-in groove 5 of Telescopic handle 4 both sides through embedding after the screw hole 2 be arranged on handle 1, Telescopic handle 4 is fixed in handle 1, hollow structure is provided with in handle 1, Telescopic handle 4 by sliding thus reaching the flexible object of handle 1 in handle 1, the width of draw-in groove 5 is greater than the diameter of the screw rod of trip bolt 3, the length of Telescopic handle 4 is greater than the length of draw-in groove 5, one end of Telescopic handle 4 is fixedly connected with driving end 6, the fastened screw 3 of the other end of Telescopic handle 4 is fixed in handle 1, handle 1, the surface of Telescopic handle 4 and driving end 6 is through concentrated sulfuric acid Passivation Treatment.
The length of described Telescopic handle 4 is greater than the length of described handle 1.
The surface of described handle 1, Telescopic handle 4 and 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, first trip bolt 3 is screwed out outside draw-in groove 5, then manual adjustments Telescopic handle 4 stretches out the length of handle 1, is finally screwed in draw-in groove 5 by the screw rod of trip bolt 3 and can lock Telescopic handle 4, thus 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.
