Description
Technical field
The utility model relates to machinery and uses field of tool, is specifically related to a kind of propelling movement type screwdriver.
Background technology
Screwdriver is a kind of to be used for twisting screw to force its instrument in place, and a thin sphenocephaly is arranged usually, can insert in the line of rabbet joint or recess of screw cap.Mainly contain two kinds of a word (negative sign) and crosses (positive sign).Common hex(agonal)screw cutter in addition, hexagonal and outer-hexagonal are two kinds in comprising.The conventional screw bottle opener is to add the iron staff that can lock screw by a plastic cement handgrip, and the ratchet screwdriver then is to add a ratchet mechanism by a plastic cement handgrip.The iron staff of lock screw can be dallied clockwise or counterclockwise for the latter, reaches the efficient of promotion lock screw by the function of idle running, and do not need one by one power drill/driver (hand) to be gone back to position originally.
Screwdriver is in prior art is used, because its location shrinkage pool does not have unified standard, when using the clamping tool head, its bottom still has vacant, in the use owing under the effect of external force, can make steel ball and adapter sleeve generation mutual extrusion unavoidably, cause steel ball wearing and tearing, the big and stuck phenomenon of beating property, influence its operate as normal.
The utility model content
Technical problem to be solved in the utility model provides a kind of propelling movement type screwdriver stable, easy to operate and that reliability is high of locking.
The utility model is achieved through the following technical solutions: a kind of propelling movement type screwdriver, comprise the cutter shell, be located at the pusher of cutter shell in reaching, and the adapter sleeve of sheathed cutter shell lower end, and one end and pusher top solid, and the knife bar by adapter sleeve locking, described pusher comprises screw rod, and be sheathed on the spacer shell of screw rod lower end, the upper end of described spacer shell and knife bar holds out against mutually, knife bar is provided with the annular half slot of at least one, the position that described cutter shell lower end is used for ccontaining knife bar offers the through hole with annular half slot, and is mounted with steel ball in through hole.
As optimized technical scheme, described being positioned on the cutter shell and with the screw rod end is connected with adjusting nut.
As optimized technical scheme, the contact position of described adapter sleeve and cutter shell bottom is made as thread connecting mode, and this thread connecting mode is set to the leaning thread connection.
As optimized technical scheme, the steel ball correspondence of described through hole and built-in through hole is provided with at least two.
The beneficial effect of the utility model propelling movement type screwdriver is: the utility model utilizes adapter sleeve that steel ball is compressed, play the effect of locking knife bar, adapter sleeve is fixedlyed connected by screw thread with cutter shell connecting portion simultaneously, efficiently solve in use fixing unstable in the past, the locking steelball big shortcoming of beating, and the problem that causes tool heads long generation clamping absent-mindedness between in use, being improved to leaning thread simultaneously is connected with to be beneficial to and avoids the defective of directly back-outing adapter sleeve when adjusting knife bar length, adapter sleeve can be realized only need unscrewing and the steel ball position can be adjusted smoothly, thereby avoid the steel ball problem that drops, have simple in structure, easy to operate and reliability advantages of higher.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model propelling movement type screwdriver.
