Abstract

The invention discloses a self-locking mute roller pin wrench, and belongs to the field of wrenches. The self-locking mute roller pin wrench is characterized in that an annular body is integrally connected to the end of a handle, annular clamping piece grooves are formed in the inner circumferences of the upper end and the lower end of the annular body, a plurality of roller pins are arranged between the annular clamping piece grooves in the upper end and the lower end of the inner circumference of the annular body, a roller pin end face structure is special structure, an inner polygonal ratchet ring is arranged on the inner circumferences of the multiple roller pins, and steps are arranged on the peripheries of the two ends of each ratchet ring and located in annular clamping pieces. According to the self-locking mute roller pin wrench, under the condition that the torque of the wrench is not reduced, the rotation freedom degree of the wrench can be increased, the noise in the use process is reduced, and the convenience of the wrench is improved.

Description

technical field [0001] The invention relates to a wrench, in particular to a self-locking silent needle roller wrench, which belongs to the field of wrenches. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or sleeves that hold bolts or nuts. Wrenches are usually made of structural steel of carbon or alloy materials. [0003] Wrenches are usually provided with openings or sleeve holes for clamping bolts or nuts at one or both ends of the shank. When in use, an external force is applied to the shank along the thread rotation direction to twist the bolts or nuts. [0004] The commonly used adjustable wrench and dead wrench are sometimes limited by the installation position of the bolt or nut, and sometimes cannot be snapped into the rotation direction of the bolt head or nut. The object cannot be rotated, and in the process of screwi...
