[0002] There are two tightening methods in the bolt tightening machine. One is torque tightening, which is to tighten the bolt to a set torque to achieve locking; the other is angle tightening, which is to tighten the bolt to a certain torque and then rotate the bolt to a set angle to achieve locking.

[0003] A search of a Chinese patent with publication number CN207649816U reveals a torque test tool for a bolt tightening machine. The tool includes a bracket and a digital torque meter. A sleeve with a square slot is located on the left side of the bracket, which mates with the digital torque meter.

[0004] Based on the above search and combined with the existing technology, we found that:

[0005] During the torque test of the existing bolt tightening machine, the height of the output end of the bolt tightening machine needs to be positioned because different models of bolt tightening machines have different heights. Most height positioning operations of the bolt tightening machine are relatively cumbersome and thus inconvenient to use. Utility Model Content

[0010] In some embodiments, a return spring is provided in each of the two mounting rods, and two ends of the return spring are fixedly connected to the mounting rod and the movable rod respectively.

[0011] In some embodiments, a motor is fixedly connected to the top of the base plate, and an output end of the motor is fixedly connected to the bottom end of the rotating column.

[0013] In some embodiments, a vertical rod is fixedly connected to the top of the base plate, a fixing column is slidably sleeved on the top of the vertical rod, and a groove is formed on the top of the fixing column.
