The falling device 4 comprises a fixed plate 401 connected with the power device 3, the fixed plate 401 and the power device 3 are mutually perpendicular, a force value sensor 402 is fixedly installed on the fixed plate 401, one end of the force value sensor 402 is fixedly connected with the fixed plate 401, and the other end of the force value sensor 402 is fixedly connected with a connecting plate 403. A force value sensor 402 is located between the fixed plate 401 and the connection plate 403. The other side of the connecting plate 403 is fixedly provided with an electromagnetic releaser 406, and the electromagnetic releaser 406 and the force value sensor 402 are respectively positioned on two sides of the connecting plate 403. Linear bearings 405 are disposed on two sides of the electromagnetic releaser 406, and the two linear bearings 405 are fixedly mounted on the connecting plate 403 respectively. The connecting rod 404 is slidably mounted in the linear bearing 405, one end of the connecting rod 404 is fixedly connected with the transition plate 408 through a bolt, the transition plate 408 is a metal object made of a component containing a magnet, and the component of the magnet is an atom such as iron, cobalt, nickel and the like. When the electromagnetic release 406 is energized, the middle portion of the transition plate 408 is magnetically coupled to the electromagnetic release 406. The electromagnetic release 406 is positioned between the transition plate 408 and the connection plate 403. The other end of the connecting rod 404 is fixedly provided with a baffle, and the baffle is fixedly connected with the connecting rod 404 through bolts. The transition plate 408 is sleeved with two adjustable connecting rings 407, and the connecting rings 407 are provided with connecting holes for adapting to the transition plate 408. The connecting ring 407 is provided with a threaded hole which is connected with the connecting hole in a penetrating way by sleeving the connecting hole on the transition plate 408, and one end of the bolt is abutted with the transition plate 408 by connecting the bolt in the threaded hole in a threaded way, so that the connecting ring 407 is fixed on the transition plate 408. When the distance adjustment is needed, only the bolts are required to be loosened, and the connecting rings 407 slide on the transition plates 408, so that the distance between the two connecting rings 407 can be correspondingly adjusted. The two connecting rings 407 are connected with fixed rings 411, one of the fixed rings 411 is fixedly connected with one of the connecting rings 407 through bolts, and the other fixed ring 411 is magnetically connected with the other connecting ring 407 under the action of the electromagnetic releaser 406.
