[0022] A placement groove is provided at one end of the rotating plate 6 close to the moving column 4, a placement shaft is fixedly sleeved on the inner side wall of the placement groove, and a roller 7 is fixedly sleeved on the outer side wall of the placement shaft. The roller 7 allows the moving column 4 to contact the roller 7 well and drive the rotating plate 6 to deflect. Two symmetrically arranged mounting shafts 5 are fixedly connected to the outer side wall of the support plate 2, and the rotating plate 6 is rotatably sleeved on the outer side wall of the mounting shaft 5;

[0023] The rotating plate 6 is provided with a mounting groove 10, and the mounting groove 10 is connected to the fixed plate 11 through a replacement mechanism. The replacement mechanism includes two plug-in plates 12 fixedly connected to the bottom of the fixed plate 11 and symmetrically arranged. The plug-in plates 12 are vertically arranged, and a socket 13 is provided on the plug-in plate 12. The rotating plate 6 is provided with a first slot 14 connected to the mounting groove 10, and the first slot 14 is adapted to the plug-in plate 12. The plug-in plate 12 is inserted into the first slot 14. The rotating plate 6 is provided with two second slots 16 that are vertically and symmetrically arranged. The rotating plate 6 is provided with a third slot 8 connected to the first slot 14 and the second slot 16, and the third slot 8 is horizontally arranged;

[0024] The inner wall of the second slot 16 is slidably connected to the first driving rod 17, and the top of the first driving rod 17 is fixedly connected to the handle 9, and the inner wall of the third slot 8 is slidably connected to the second driving rod 15.

Since the diameter of the moving column 4 gradually increases from left to right in the direction shown in the figure, that is, when the moving column 4 gradually moves between the two rollers 7, the two rotating plates 6 form a lever under the action of the mounting shaft 5, thereby moving the two fixed plates 11 toward the opposite side, thereby fixing the head of the bolt, and then the torque of the bolt is detected by the torque detector body;

[0027] When it is necessary to test the fan bolts of different specifications, it is only necessary to pull the handle 9 by hand. The handle 9 drives the first drive rod 17 to move upward. The first drive rod 17 moves the second drive rod 15 through the third drive rod 19, so that the second drive rod 15 is taken out of the socket 13 on the plug plate 12, and then the fixing plate 11 is removed and replaced with different types of fixing plates 11, which is convenient for fixing bolts of different specifications, thereby realizing rapid detection of the torque of fan bolts of different specifications, thereby improving the practicability of the device.
