[0021] The anti-loosening alarm mechanism includes a connecting plate 22 slidably installed in the fixing seat 20, and two second connecting rods 23 are fixedly installed on the side of the connecting plate 22 close to the placing table 4, and the other ends of the two second connecting rods 23 extend to the outside of the fixing seat 20 and are fixedly installed with the same resisting plate 15, and a buffer pad 16 is fixedly installed on the side of the fixing seat 20 close to the resisting plate 15, and a second conductive sheet 21 is fixedly installed on the side of the connecting plate 22 away from the resisting plate 15, and a first conductive sheet 19 is fixedly installed on the inner wall of the side of the fixing seat 20 close to the connecting plate 22. When the first conductive sheet 19 and the second conductive sheet 21 are in contact, the flashing light 13 lights up, and the flashing light 13 lights up, indicating that it is firmly fixed, and when the flashing light 13 is off, it means that it is loose and not fixed tightly. The flashing light 13 is fixedly installed on the other side of the fixing seat 20.

[0022] Two second limit rods 17 are fixedly installed in the fixed seat 20, and the two second limit rods 17 can limit the moving direction of the connecting plate 22. The connecting plate 22 is slidably installed on the two second limit rods 17. A spring 18 is fixedly installed on the side of the connecting plate 22 away from the resisting plate 15. The spring 18 is reset due to stretching.

[0023] A rotating seat 7 is fixedly mounted on one side of the second supporting plate 24 close to the first supporting plate 8 , and one end of the first screw rod 9 is rotatably mounted on the rotating seat 7 .

The round-edge handwheel 2 drives the second screw 10 to rotate, and the second screw 10 drives the first screw 9 to rotate through the connecting block 14. At this time, the two first connecting rods 12 on the first screw 9 and the second screw 10 begin to move toward each other. When the first connecting rod 12 moves to a certain distance, the resistance plate 15 contacts the outside of the oil pump. Due to the force of continuing to move toward each other, the resistance plate 15 moves the connecting plate 22 through the second connecting rod 23, and the spring 18 is compressed, and the connecting plate 22 is close to the first conductive sheet 19.
