[0002] Conventional screwdrivers are fixed on the handle with a steel blade. For different screw head patterns, different screwdrivers are required. Therefore, different screwdrivers need to be prepared for different screws, which is inconvenient to use, carry and store. Replace the screwdriver with the steel blade. The steel blade is directly inserted into the hexagonal groove at one end of the handle through the hexagonal structure. Torque, not suitable for torque operation, and the hexagonal groove of the handle is easy to wear and damage, resulting in failure to use normally

The invention discloses a steel blade quick-changing chuck which comprises a steel blade, a handle and a quick-changing chuck body. The quick-changing chuck body is fixedly installed at one end of the handle, a pattern matched with the head of a bolt is formed at one end of the steel blade, and the other end of the steel blade just can be inserted into the quick-changing chuck body and locked and clamped by the quick-changing chuck body. The quick-changing chuck body is arranged on the handle, so that rapid assembly, disassembly and replacement of the steel blade can be achieved, user is convenient, large torsion operation can be borne, and the steel blade is firm, stable, free of disengagement, durable in use and not prone to abrasion and damage after being installed.
Description
technical field [0001] The invention relates to the technical field of screwdrivers, in particular to a steel blade quick-change chuck. Background technique [0002] Conventional screwdrivers are fixed on the handle with a steel blade. For different screw head patterns, different screwdrivers are required. Therefore, different screwdrivers need to be prepared for different screws, which is inconvenient to use, carry and store. Replace the screwdriver with the steel blade. The steel blade is directly inserted into the hexagonal groove at one end of the handle through the hexagonal structure. Torque is not suitable for torque operation, and the hexagonal groove of the handle is easy to wear and damage, resulting in failure to use normally. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a steel blade quick-change chuck, which has a simple structure, is easy to use, and is applicable to the operation of diff...
