Abstract

A three gear-position ratcheting tool comprising a handle (1), a mounting base (2) having an accommodating groove (21) and provided on at least one extremity of the handle (1), a cover (22) provided on the mounting base (2), a mounting hole (23) provided on the mounting base (2), a rotating bushing (3) provided in the mounting hole (23), a tool head (31) provided on at least one extremity of the rotating bushing (3), a ratchet (32) having ratchet teeth (321) and provided on the circumferential exterior of the rotating bushing (3), two paws (4) provided in the accommodating groove (21), and a toggling base (5) provided on the mounting base (2) and capable of swinging in the circumferential direction thus controlling either of the paws (4) to mesh with the ratchet teeth (321) or simultaneously both of the paws (4) to mesh with the ratchet teeth (321), where one extremity of the switching base (5) is extended to the outside of the mounting base (2), the other extremity is abutted against the cover (22), and a toggling lock mechanism provided between the toggling base (5) and the cover (22).

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a ratchet tool, in particular to a three-speed positioning ratchet tool. Background technique [0002] Ratchet tools are widely used in daily life. They are mainly used to remove or install fasteners. For example, a common ratchet wrench is a manual screw tightening tool. The existing ratchet wrench includes a handle and a ratchet mechanism. The ratchet mechanism includes a handle column, a direction limiting tooth, a reversing member and a ratchet. It is connected with the shank that can rotate relatively. The reversing member is provided with a top block for controlling the combination of the direction-limiting teeth and the toothed ratchets; Fixed set with magnets. There are many deficiencies in this ratchet wrench. For example, the existing ratchet wrench generally only has two use states of forward and reverse rotation. It is inconvenient to switch forward or re...
