Description

Ratchet wrench with adjustable tooth number

Technical Field

The utility model relates to a spanner, more specifically say, it relates to a number of teeth adjustable ratchet spanner.

Background

A wrench is a common installation and removal tool. Hand tools for turning bolts, screws, nuts and other threaded fasteners for tightening openings or trepanning of bolts or nuts using the principle of leverage.

A ratchet wrench is a kind of wrench, and is generally used for rotating a bolt or a nut placed in a narrow or difficult-to-access position, the minimum rotation angle of the ratchet wrench is related to the number of teeth of the ratchet body, the smaller the number of teeth, the larger the minimum rotation angle, and the larger the number of teeth, the smaller the maximum rotation angle, so that the position of the bolt or the nut is narrower compared to the position of the ratchet wrench with the smaller the number of teeth.

The number of teeth of the ratchet main body on the ratchet spanner is fixed usually, can't adjust, need the more ratchet spanner of number of teeth when the position that bolt or nut were located is very narrow, be fit for using the less ratchet spanner of number of teeth when the position that bolt or nut were located is comparatively spacious, consequently when the width degree of the position that bolt or nut were located is uncertain usually to in case need be equipped with the ratchet spanner of multiunit number of teeth, but can cause the inconvenient condition of carrying.

A new solution is therefore proposed to solve this problem.
