When the illegal person pries the cover 400, the ball 516 in the groove 515 at the top of the supporting rod 512 is shaken and thus falls off from the groove 515 and falls downward along the transparent hollow column 511. The ball 516 passes through its own weight to cooperate with the height of the supporting rod 512 and thus hits the disc 514 to apply force to the disc 514. The disc 514 in turn transmits the force to the pressure sensor 513. The pressure sensor 513 detects the change of the pressure and thus opens the alarm 519 in the pipe body 518 through the controller 517. The alarm 519 alarms to warn the illegal person and remind the staff. The key is used to rotate the lock cylinder at the first fixed plate 210 and the second fixed plate 521 to release the fixation, and the structure inside the motor 300 and the box body 500 is maintained. After the ball 516 falls, the sliding plate 510 is pulled out of the box body 500, the lifting block 531 is lifted upward, and the disc 514 is moved upward in the vertical groove 530, and the disc 514 in turn drives the ball 516 to move upward. When the ball 516 moves to the top end of the supporting rod 512, the ball 516 is slid into the groove 515 through the slope at the top of the disc 514 to reset. During maintenance, the lifting block 531 and the magnet 541 on the top plate 540 are connected through magnetism to fix the disc 514, and thus the ball 516 is limited to avoid triggering the alarm during maintenance.
