Problems solved by technology

[0002] In the process of maintenance and inspection of mechanical equipment and power facilities, the problem of disassembly and assembly of threaded connectors with narrow operating space is often encountered. Because it is difficult to directly complete the disassembly and assembly work with traditional tools, the nearby parts that hinder the operation must be removed first. , so it not only increases the workload of the maintenance personnel and prolongs the maintenance time, but also the frequent disassembly and assembly of some parts will affect the assembly accuracy of the equipment and cause adverse effects on the normal operation of the equipment

Abstract

The invention provides a multifunctional wrench applicable to narrow operation space, which comprises a handle, a rod arm, a connecting rod, a bevel gear steering mechanism and a connector, wherein the handle is fixed at the front end of the rod arm; the rear end of the rod arm is assembled with the front end of the connecting rod; the rear end of the connecting rod is assembled with the front end of the bevel gear steering mechanism; the rear end of the bevel gear steering mechanism is assembled with the connector; and the connector is matched with a screwed fitting to be dismounted. The multifunctional wrench provided by the invention is applied to maintenance of mechanical devices and electric facilities. Because of avoiding dismounting parts near the screwed fitting to be dismounted, the multifunctional wrench provided by the invention shortens the maintenance time of the device and greatly improves the working efficiency on one hand, and maintains the original assembling precision of the device and guarantees the normal running of the device on the other hand.

Description

technical field [0001] The invention relates to a wrench for disassembling and assembling threaded connectors, in particular to a multifunctional wrench suitable for operation in a narrow space, and belongs to the technical field of hand tools.
