Abstract

The invention discloses a mechanical spanner convenient to use and wide in application range. The mechanical spanner comprises a mounting plate. A rotary shaft is rotationally mounted on the outer side wall of one side of the mounting plate, a handle is fixedly mounted at the end, away from the mounting plate, of the rotary shaft, the handle comprises a fixed handle fixedly mounted on the rotary shaft and multiple movable handles detachably mounted on the fixed handle, and connecting devices are arranged between the movable handles and the fixed handle and between every two adjacent movable handles. During use, a connecting sleeve is connected to a bolt or a screw, plugs are inserted into corresponding jacks, the mounting plate and the connecting sleeve can be driven to twist the bolt or the screw by rotating the handle, after the handle rotates by a certain angle, the plugs are pulled out, the handle is rotated, then the plugs are inserted into the jacks again, the bolt or the screw can continue to be twisted, the bolt or the screw can be conveniently continuously twisted without detaching the connecting sleeve from the bolt or the screw, use is convenient, and the twisting rate of the bolt or the screw is greatly increased.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to a mechanical wrench which is easy to use and has a wide application range. 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 threaded openings or sockets that hold bolts or nuts. The wrench is usually at one or both ends of the handle. There are openings or sleeve holes for clamping bolts or nuts. When using, an external force is applied to the handle along the thread rotation direction to twist the bolts or nuts. The wrench is usually made of carbon or alloy structural steel. [0003] When the existing mechanical wrench is screwing the bolt or screw, it is often impossible to turn the mechanical wrench completely due to the small installation space. When using it, it is necessary to turn the mechanical wrench to a small angle and remove the mechan...
