Description

A kind of telescopic sleeve screwdriver
Technical field
The utility model relates to a kind of screwdriver, and specifically a kind of telescopic sleeve screwdriver, belongs to machine tool technical field.
Background technology
As everyone knows, screwdriver is generally made up of handle, knife bar and driver bit, is specially adapted to tighten or unscrew the screw be in compared with deep location.
Often need to use screwdriver to carry out dismounting and fastening to screw in machine work.In production and life, the structure of widely used screwdriver is all generally fixing at present, cannot by regulating the length of knife bar thus tightening the screw being in different depth position or unscrew, the screwdriver needing workmen to carry multiple different length specification is caused to tighten the screw being in different depth position or to unscrew, therefore, in the urgent need to invent a kind of can by regulating the length of knife bar thus the screwdriver tightened the screw being in different depth position or unscrew.
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 by regulating the length of knife bar thus the telescopic sleeve screwdriver tightened the screw being in different depth position or unscrew.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of telescopic sleeve screwdriver, comprises handle, knife bar, through hole, screw hole, trip bolt, expansion link, chute, collet head, it is characterized in that: one end of described handle is provided with knife bar, through hole is provided with in knife bar, knife bar is provided with screw hole, be provided with in screw hole and tightly enclose screw, expansion link is provided with in knife bar, the both sides of expansion link are provided with chute, one end of expansion link is provided with collet head, one end of handle is fixedly connected with one end of knife bar, and one end and the through hole be arranged in knife bar of expansion link are slidably matched, and one end of expansion link is fixedly connected with the top of collet head, after one end of expansion link enters the through hole be arranged in knife bar, trip bolt is through the screw hole be arranged on knife bar and embedding is arranged in the chute of expansion link both sides, and be fixed on by expansion link in knife bar, the length of expansion link is greater than the length of chute, the length of expansion link is greater than the length of knife bar, handle, knife bar is cylindrical structural, handle, knife bar, trip bolt, expansion link, the surface of collet head through concentrated sulfuric acid Passivation Treatment, through hole, expansion link is regular polygon structure, and the length of expansion link is greater than the height of collet head.
The length of described knife bar is greater than the length of described chute.
The surface of described handle, knife bar, trip bolt, expansion link, collet head is through concentrated sulfuric acid Passivation Treatment, and object improves the resistance to corrosion of screwdriver, 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 by regulating the length of knife bar thus tightening the screw being in different depth position or unscrew, effectively reduce the quantity of the screwdriver carried required for workmen, not only can reduce use cost, and the labour intensity of workmen can be reduced, be 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-knife bar, 3-through hole, 4-screw hole, 5-trip bolt, 6-expansion link, 7-chute, 8-collet head.
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 sleeve screwdriver, comprises handle 1, knife bar 2, through hole 3, screw hole 4, trip bolt 5, expansion link 6, chute 7, collet head 8, it is characterized in that: one end of described handle 1 is provided with knife bar 2, through hole 3 is provided with in knife bar 2, knife bar 2 is provided with screw hole 4, trip bolt 5 is provided with in screw hole 4, expansion link 6 is provided with in knife bar 2, the both sides of expansion link 6 are provided with chute 7, one end of expansion link 6 is provided with collet head 8, one end of handle 1 is fixedly connected with one end of knife bar 2, and one end and the through hole 3 be arranged in knife bar 2 of expansion link 6 are slidably matched, and one end of expansion link 6 is fixedly connected with the top of collet head 8, after one end of expansion link 6 enters the through hole 3 be arranged in knife bar 2, trip bolt 5 is through the screw hole 4 be arranged on knife bar 2 and embedding is arranged in the chute 7 of expansion link 6 both sides, and be fixed on by expansion link 6 in knife bar 2, the length of expansion link 6 is greater than the length of chute 7, the length of expansion link 6 is greater than the length of knife bar 2, handle 1, knife bar 2 is cylindrical structural, handle 1, knife bar 2, trip bolt 5, expansion link 6, the surface of collet head 8 through concentrated sulfuric acid Passivation Treatment, through hole 3, expansion link 6 is regular polygon structure, and the length of expansion link 6 is greater than the height of collet head 8.
The length of described knife bar 2 is greater than the length of described chute 7.
The surface of described handle 1, knife bar 2, trip bolt 5, expansion link 6, collet head 8 is through concentrated sulfuric acid Passivation Treatment, and object improves the resistance to corrosion of screwdriver, to adapt to the severe working environment of various complexity.
In time needing the length regulating knife bar 2, first unscrew trip bolt 5, then manual adjustments expansion link 6 stretches out the length of knife bar 2, finally screws trip bolt 5 and can lock expansion link 6, thus reaches the object of the length regulating knife bar 2.
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.
