Description
Technical field
The utility model relates to a kind of electric tool, particularly a kind of electric screw driver that is applicable to screw, nut dismounting.
Background technology
At present, the electric screw driver product category on the market is various because easy to use, efficient is high, is used widely in all trades and professions, and is especially obvious on assembling line especially; But existing electric screwdriver structure still exists unreasonable part, the one, be connected with reed between positioning sleeve and the locking sleeve, and the reed back easy deformation of quenching, size is difficult to grasp, and causes easily to come off, and service life is short; The 2nd, install, dismantle, repair inconvenient.For this reason, many manufacturers and knowledgeable people have carried out improvement and research repeatedly, design many different schemes, but do not have ideal method to solve the problems referred to above so far as yet.
Summary of the invention
For solving the problems referred to above that existing electric screw driver exists, the utility model provides the electric screw driver of a kind of simple and reasonable, easy installation and removal, long service life.The technical scheme that its technical problem that solves the utility model adopts, it comprises body, positioning sleeve, locking sleeve, regulating sleeve, the screwdriver assembly, connecting rod, the ratchet axle, the compression spring, ratchet, positioning sleeve is fixed on the head capsule of body, regulating sleeve is enclosed within on the positioning sleeve, described locking sleeve one end is socketed in positioning sleeve, the other end is connected with regulating sleeve by threaded engagement, locking sleeve is provided with two annular grooves, in every annular groove, be provided with three equally distributed apertures, ball is set in the aperture, on every annular groove, be provided with elastic ring, wherein an annular groove is arranged on the joint portion corresponding with positioning sleeve, positioning sleeve is provided with the arc groove that cooperates with ball, another annular groove is arranged on the joint portion corresponding with regulating sleeve, is provided with three circular arc straight troughs that cooperate with ball on the regulating sleeve at least.
Described locking sleeve is provided with standby groove, is provided with spare rings in the groove.
After adopting said structure, locking sleeve is under the elastic force effect of elastic ring, and the arc groove of ball and positioning sleeve closely cooperates, and makes it to form longitudinal register, guarantees that locking sleeve can rotate around positioning sleeve, can not separate with positioning sleeve again to come off; Locking sleeve is under the elastic force effect of elastic ring, and the circular arc straight trough of ball and regulating sleeve closely cooperates, and makes it to form radial location, and when guaranteeing electric screw driver work, regulating sleeve can not rotate with the screwdriver assembly; Have advantages such as simple and reasonable, easy installation and removal, long service life.
Description of drawings
