Summary of the invention
The objective of the invention is to aim at the large weak point of difficulty for slotted screw, provide a kind of and save time, laborsaving, can improve the slotted head screw efficiency of assembling, alleviate working strength, the auto-alignment screw slots, the automatic precession assembly tool of the slotted head screw that can not skid off from the screw slots side.
The technical solution adopted for the present invention to solve the technical problems is, a kind of slotted head screw is from advancing rotating tool, comprise a polished rod screwdriver that is shaped with flat-shaped straight screwdriver head, it is characterized in that, polished rod at described straight screwdriver is set with back-moving spring and guide, guide is conflicted on the end face of described back-moving spring by the polished rod of described straight screwdriver, and described straight screwdriver head is inserted in the flat recess of head of screw by the guide rotation.
The present invention has following beneficial effect than prior art.
The present invention adopts polished rod suit back-moving spring and the guide at straight screwdriver, although the function of screwdriver is the same with normal screws cutter function, guide requires to use manually or automatically device drives continuous rotation, but compares with hand-held normal screws cutter intermittent rotary screwing, owing to can make screwdriver automatically import head of screw, embed screw slots, the alignment screw groove, the screwdriver continuous rotation drives the screw synchronous rotary, in rotary course, screwdriver can not skidded off from the screw slots side.Back-moving spring allows guide to slide under external force left, so that slotted head screw exposes from guide, is assembled in the screw hole of union piece, and after assembling was finished, back-moving spring resetted guide 3, can conveniently enter next operation.Flexible operation, convenient, contraposition saves time, laborsaving accurately and reliably very much, can significantly improve the efficiency of assembling of slotted head screw, alleviates working strength.
Adopt screwing of the present invention than fast 2 ~ 3 times of hand-held normal screws cutter intermittent rotary screwing.For the injection moulding union piece, the undressed screw thread of screw hole produces screw thread by the screw self tapping, and not only efficient is high with this assembly tool, and is also more laborsaving.
