A high-efficiency continuous rotation hand screwdriver

Abstract

The invention discloses an efficient continuous rotary hand-rotating tool, and belongs to the field of hand tools. The defect of the need of operating the rotating direction with a hand in real time exists in the conventional hand-rotating tool. A plurality of slotted holes are formed in the radial directions of a front ratchet jaw and a back ratchet jaw; the slot teeth of the front and back ratchet jaws are meshed with annular teeth at the longer ends of front and back ratchet gears respectively; the front and back ratchet jaws are correspondingly embedded into installing holes in the larger-diameter ends of front and back ratchet jackets, and are clamped by using buckles; front and back reserving rings are sleeved on the front and back ratchet jackets respectively through springs and steel balls; the smaller-diameter ends of the front and back ratchet jackets are spliced into installing holes of front and the back handles respectively; a fixed plate on which a gear is arranged through a pin shaft is embedded into the back ratchet jacket; the gear is in meshed connection with annular teeth at shorter ends of front and back ratchet gears; the back end of a socket extension is inserted into a front handle, a front ratchet gear and a back ratchet gear in sequence; the sleeve extension is provided with a clamp spring; the clamp spring is attached to the front end face of the front ratchet gear. By adopting the efficient continuous rotary hand-rotating tool, the socket extension can be rotated and operated continuously in the same direction.

Description

technical field [0001] The invention belongs to the technical field of screwdrivers and hand tools, and in particular relates to a high-efficiency continuous rotation hand screwdriver capable of directional and continuous rotation control. Background technique [0002] The traditional hand spinner includes a knife rod, a socket rod, a metal ferrule, a pin and a handle. The rear end of the socket rod is fixed on the handle through a metal ferrule and a pin. The front end of the rod is convenient for the exchange of different tool rods. However, such a structure can only be controlled by hand in real time in a single direction of rotation, which is likely to cause fatigue to the operator and result in low work efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the existing hand spinner needs to control the rotation direction by hand in real time, and provide a high-efficiency continuous rotation hand spinner tha...
