Description

A V-type thrust rod installation wrench

Technical Field

The invention relates to a V-shaped thrust rod installation wrench, which is specifically suitable for improving the installation efficiency of the V-shaped thrust rod.

Background technique

A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners with openings or holes. Wrenches are usually made of structural steel made of carbon or alloy materials. Wrenches usually have openings or holes for clamping bolts or nuts at one or both ends of the handle. When used, external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.

The utility model patent with Chinese patent publication number CN205630431U and publication date October 12, 2016 discloses a replaceable clamp-type wrench, including a right handle, a left handle and a combined clamp plate, the top ends of the right handle and the left handle are movably connected by a pin, and the right handle and the left handle are respectively provided with a left mounting groove and a right mounting groove, and the left mounting groove and the right mounting groove are both provided with screw holes; the combined clamp plate is composed of a left clamp plate and a right clamp plate, the left clamp plate and the right clamp plate are respectively provided with a left jaw and a right jaw, and the left clamp plate and the right clamp plate are respectively provided with a through hole that matches the screw hole. Although the utility model can conveniently tighten the nut, it still has the following defects:

The utility model can only clamp a single nut, and when it is used for a V-shaped thrust rod, the installation speed is slow and the installation efficiency is low.
