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 extension type sleeve screw driver 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 extension type sleeve screw driver, comprise handle, knife bar, circular hole, screw hole, trip bolt, spring, slide block, screw rod, adjusting nut, collet head, it is characterized in that: one end of described handle is provided with knife bar, circular hole is provided with in knife bar, one end of handle is fixedly connected with one end of knife bar, knife bar is provided with screw hole, trip bolt is provided with in screw hole, spring is provided with in circular hole, slide block and screw rod, one end of spring is fixedly connected with the bottom of circular hole, 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 and collet head, the other end of screw rod is fixedly connected with collet head, after slide block enters the circular hole be arranged in knife bar, trip bolt is through the screw hole be arranged on knife bar, slide block is fixed in circular hole.
The length of described screw rod is greater than the length of described slide block.
The length of described slide block is greater than the drift of described spring.
Described handle, knife bar are cylindrical structural.
The length of described knife bar is greater than the length of described handle.
The length of described knife bar is greater than the length of screw rod.
The surface of described handle, knife bar, trip bolt, spring, slide block, screw rod, adjusting nut, collet head is through the concentrated sulfuric acid or red fuming nitric acid (RFNA) 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.
