Abstract
A hand-pressed self-rotation type screwdriver comprises a one-way mechanism, a ball screw mechanism, a returning mechanism, a (an) lower casing/upper casing and an organic sleeve. The one-way mechanism is provided with an inner pipe fitting, a limiting conduit, a pair of steel balls, a lower spring and a rear press cover. The ball screw mechanism comprises a screw and a pair of steel balls. The returning mechanism comprises two springs. By pressing the rear press cover and the screw, the screw can be obliged to carry out helical motion relative to a casing so as to achieve the effect of tightening or dismantling the screw; when pressure is removed, the returning mechanism can oblige every mechanism to return; and when the screw is tightened, only extrusion motion needs to be performed through the hand-pressed self-rotation type screwdriver, and the effects of time saving and convenience are achieved.
Description
Technical field
The present invention relates to a kind of screwdriver, particularly a kind of long service life, quick detachable, pressure is converted to rotatablely move, stroke is long and compression travel finishes the back screw rod hand self-rotary screwdriver that resets of translation automatically.
Background technology
In the prior art, the screwdriver loading and unloading screw that generally uses once can only rotate half-turn, and speed is very slow.
A kind of left handed screw cutter and dextrorotation screwdriver were arranged in the past, and its practicality still has disappearance to exist.Though this screwdriver can drive the screw fast rotational, but because the screw mandrel diameter of its ball wire rod mechanism is too big, cause stroke shorter, in addition after the compression travel of screwdriver finishes, need reverse rotation again to get back to the initialization position, this in actual use the stand-by period longer, and block easily, very inconvenient.
Electric screw driver was arranged, but the general volume of electric screw driver is bigger in the past, and needs external power supply, a lot of occasions are not suitable for using.
Summary of the invention
The object of the invention be to provide a kind of long service life, quick detachable, do not need external power supply, pressure is converted to rotatablely move, stroke is relatively long and compression travel finishes the back screw rod hand self-rotary screwdriver that resets of translation automatically.
The invention provides a kind of hand self-rotary screwdriver, comprise a unidirectional mechanism, ball wire rod mechanism, resetting-mechanism, lower casing, one go up shell and one mantle arranged;
