[0030] Furthermore, the latching mechanism includes a locking rod 5 inserted into the slot 43. A pinch block 51 is fixedly connected to the end of the locking rod 5 away from the slide groove 52. The pinch block 51 provides leverage when manually inserting or removing the rod from the slot 43, thus reducing effort during insertion and removal. The slot 43 has multiple pairs of linearly arranged anti-disengagement grooves 44 inside. One end of the locking rod 5 has a pair of slide grooves 52. A return spring 53 is fixedly connected inside the slide groove 52.

The vibration sensor 6 is an electronic device used to detect and measure the vibration or acceleration of an object. It can sense the vibration of an object's surface and convert it into an electrical signal. It is typically used to monitor the health status of mechanical equipment, structural safety, process control, and other situations requiring vibration analysis. It is used to improve safety, warn of dangers, or alert users to the occurrence of certain abnormalities.

[0033] In this embodiment, when an intelligent screening machine is required, such as Figure 1As shown, the vibration sensor 6 on the outer wall of the screening machine body 1 detects the vibration generated by the operation of the screening machine body 1 to be abnormal. At this time, the vibration sensor 6 will send a signal to the controller 7, and the controller 7 will send an instruction to the alarm 8 after receiving the signal. The alarm 8 will operate to generate an alarm sound after receiving the instruction, thereby reminding the staff that the screening machine body 1 operation is abnormal. When it is necessary to disassemble and maintain the first screening layer 11, the second screening layer 12, the third screening layer 13 and the top cover 14, it is only necessary to manually pinch the pinch block 51 and force the end of the locking rod 5 to be pulled out of the clamping groove 43. At this time, the rotating head 41 can be pinched and rotated. Since the rotating head 41 drives the screw rod 4 to rotate and is screw-connected with the second connecting block 22, the screw rod 4 is quickly detached from the second connecting block 22, so that the first screening layer 11, the second screening layer 12, the third screening layer 13 and the top cover 14 can be quickly disassembled and assembled. When the first connecting block 21 and the second connecting block 22 at both ends of the tightening belt 2 need to be connected through the screw rod 4, it is only necessary to pass the screw rod 4 through the first connecting block 21 and screw-connect it with the second connecting block 22. At this time, it is only necessary to manually rotate the rotating head 41 for several turns, and insert the locking rod 5 into the clamping groove 43. The protrusion 55 abutting against the inner wall of the clamping groove 43 will be retracted into the sliding groove 52. After the protrusion 55 moves to coincide with the anti-dropping groove 44 in the clamping groove 43, the sliding plate 54 will be elastically pushed by the elastic force of the return spring 53. The sliding plate 54 drives the corresponding protrusion 55 to be clamped into the corresponding anti-dropping groove 44. Finally, the screw rod 4 cannot be reversely rotated and detached from the second connecting block 22, which is simple and easy to operate.
