Description

technical field [0001] The invention belongs to the field of hardware tools, in particular to a screwdriver with adjustable torque. Background technique [0002] Screwdrivers are widely used in the installation and disassembly of mechanical equipment, and have become an indispensable tool in the mechanical field. With the development of science and technology, the structure of the mechanical equipment is becoming more and more complex, and the manufacturing is becoming more and more refined. There are many kinds of screws used, and they are limited to certain requirements. The installation parts are relatively remote, such as some corners. Screwdrivers are all fixed and cannot be turned, which is inconvenient for disassembly and assembly of screws, and most of the torques are not adjustable, which may cause the risk of thread teeth jumping off. Therefore, it is necessary to develop a screwdriver that can be turned and has high reliability. Contents of the invention [000...
