Abstract

The head-adjustable ratchet wrench with the telescopic handle comprises a wrench body, an angle adjusting block, a first handle and a second handle, one end of the angle adjusting block is fixedly connected with the wrench body, and a nut connector is fixedly installed on the wrench body and can rotate along with the wrench body; the other end of the angle adjusting block is movably connected with the first handle, so that the angle adjusting block can rotate relative to the first handle under the action of external force and can be static after rotating to a set position, the first handle is fixedly connected to the second handle, and the length of the second handle can be adjusted. The head-adjustable ratchet wrench with the telescopic handle can be used under narrow and complex working conditions, the wrench can be in butt joint with a nut to be unscrewed conveniently, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical tools, in particular to a head-adjustable ratchet wrench with a telescopic handle. Background technique [0002] Ratchet wrench is widely used because of its small working swing angle, convenient use and high efficiency. At present, there are many kinds of adjustable ratchet wrenches on the market, and the structure is simple, but there are still the following deficiencies: 1) The angle of the head of the ratchet cannot be adjusted, and it is not easy to align with the nut and the screw at the nut interface during work; 2) In some narrow operating spaces, the handle The length does not meet the needs of the job. Contents of the invention [0003] In view of this, the present invention aims to provide an adjustable head ratchet wrench with a telescopic handle to solve the problems of non-adjustable ratchet head angle, non-adjustable handle length and limited operating space. [0004] In order to achie...
