Description

Technical Field

[0001] The utility model relates to the technical field of tightening tools, in particular to a tightening device with a quick-release structure. Background Art

[0002] In current industrial production, most of the connections between two parts are made with fasteners. Currently, tightening devices are used for tightening, which is convenient, labor-saving and has high tightening efficiency. The current tightening device uses a tightening tool such as a screwdriver to drive the bit to rotate, and the bit drives the screw to rotate to complete the tightening. The screw is fed from the swing arm to the front end of the vacuum tube. The vacuum tube moves and pushes the upper swing arm, driving the screw to extend from the gun head. The bit then tightens the screw. However, the screw will get stuck at the end of the swing arm. At this time, the swing arm needs to be removed to remove the stuck screw. Currently, removing the swing arm is relatively cumbersome. There are many types of screws, so corresponding bits are required. When replacing a screw, the corresponding bit also needs to be replaced. Currently, one end of the bit is installed on the vacuum tube and the other end is installed on the output end of the screwdriver, which makes it difficult to remove the bit. The specific trouble is that the tightening tool needs to be removed. Therefore, the current tightening device is inefficient in removing the swing arm and replacing the bit. Utility Model Content
