Angle-adjustable wrench

Abstract

The invention discloses a wrench with adjustable angle, which comprises a connecting rod, a functional block, and a connecting rod. A handle is arranged in the middle of the connecting rod, and connecting heads are arranged at both ends of the handle. Through holes, the function block is provided with a connection block, the left side of the connection block is provided with a function head, and a through hole is provided inside, and a round hole is arranged inside the function head, and several card slots are evenly distributed on the inner wall of the round hole, a connecting rod is provided with a connecting shaft, and a threaded stop is provided at the upper end , the connecting shaft penetrates into the through hole and the through hole one, the threaded block is screwed with the screw hole, the tail end of the threaded block is provided with a slot, and the through hole one and the connecting block are vertically arranged. The functional block of the present invention is connected to the The rod is movably connected and can be adjusted up and down when in use, which is convenient for adjusting the rotation position and direction according to the space and position restrictions of the use area.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a wrench with adjustable angle. Background technique [0002] A wrench is an essential tool for tightening bolts and nuts during maintenance. There are many types of wrenches, but they can be roughly divided into straight wrenches and socket wrenches. Straight wrenches hold bolts and nuts horizontally, with long arm and direct torque. The space in the area needs to be sufficient. The socket wrench is used to hold the bolts and nuts upright. It can be used in a small space, but it needs to be extended upwards for a certain distance to apply a rotating torque. The effective torque is small, because the angle cannot be adjusted flexibly during use, resulting in maintenance. Personnel need to carry a lot of tools for backup when repairing municipal public facilities. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of th...
