[0059] The baffle 203a is fixed outside the support 203, and the top of the circular table 203b is at the same height as the baffle 203a. An arc slot 203c is formed in the bottom of the circular table 203b. The circular ring 203d can rotate inside the circular table 203b.

The initial position of the sliding column is located at the left side of the movable slot 204a.

[0062] The push rod 204b on the outer wall of the arc plate 204 extends out of the baffle 203a outside the support 203.

At this time, the rotation of the fan 201 does not stop, the circular ball 202c inside the inner wall containing groove 202a of the rotating disc 202 is extruded to shrink into the inner part of the containing groove 202a, so that the first elastic member 202b is extruded. At this time, the circular ball 202c is separated from the groove 201b on the surface of the rotating shaft 201a, and the rotating disc 202 does not continue to rotate.

[0065] In summary, when the placing plate 103 is deviated due to external influence during use, the side link 103c is deviated, the side of the opening 103d in the inner wall of the link 103c extrudes and pushes the pushing column 204e, so that the pushing column 204e rotates around the lower hinge point as the fulcrum, the upper movable block 204d deviates towards the support 203, driving the push rod 204b to push to the right side in the baffle 203a. At this time, the second elastic member 204c is extruded and deformed, and the arc plate 204 is deviated. When the arc plate 204 deviates towards the middle of the circular table 203b, the movable rod 202f on the surface of the rotating disc 202 contacts the side arc edge of the arc plate 204, so that the movable rod 202f moves towards the shaft center of the rotating disc 202, driving the elastic rod 202e to move, and the locking rod 202d rotates outward, the hook on the top of the locking rod 202d is engaged with the locking teeth 203e on the inner wall of the circular ring 203d, driving the circular ring 203d to rotate in the circular table 203b, driving the lower cylindrical body 203f to slide from the left side to the right side in the arc groove 203c and be limited. At this time, the rotating disc 202 cannot continue to rotate, the circular ball 202c in the inner wall of the rotating disc 202 retracts into the containing groove 202a, the rotation of the fan 201 is not affected, and the internal heat continues to be discharged to the outside, and the circular ball 202c repeats the process of engaging in the groove 201b and retracting, maintaining the state of the rotating disc 202, so that the circular ring 203d does not rotate back, and the lower cylindrical body 203f is always located on the right side of the arc groove 203c.

[0066] When the cylindrical body 203f moves from the left side to the right side in the arc groove 203c, the actuating ring 105b below the placing plate 103 moves with the cylindrical body 203f from the left side to the right side, driving the fixed ring 105 to rotate below the placing plate 103, so that the clamping rod 105h clamps the threaded cylinder 101b, fixing the placing plate 103 above the threaded cylinder 101b, so that the temperature sensing part 104 does not deviate from the original position, reducing the error of the detection data of the automatic instrument below.
