Referring to fig. 1, a spring 2 is disposed in an elastic groove 101 of a fixed plate 1, a first magnetic sheet 3 is slidably disposed in the elastic groove 101 of the fixed plate 1, and a top end of the first magnetic sheet 3 is connected to the spring 2. The first magnetic sheet 3 can reciprocate in the elastic groove 101. The guide post 4 is fixedly arranged at the bottom end of the first magnetic sheet 3, the leather plug 5 is fixedly arranged at the bottom end of the guide post 4, and when the first magnetic sheet 3 reciprocates, the guide post 4 also reciprocates.

The connecting column 6 is rotatably arranged in the thread groove 102 of the fixed plate 1, and the position of the connecting column 6 in the fixed plate 1 can be adjusted by rotating the connecting column 6. As shown in fig. 1, 3 and 4, the connecting column 6 is provided with a through hole 601, the plug 5 is slidably disposed in the through hole 601, and a ventilation groove 602 is disposed outside the bottom end of the through hole 601. When the plug 5 is positioned at the top end of the through hole 601, the through hole 601 is divided into two unvented cavities; when the leather plug 5 is positioned at the bottom end of the through hole 601, due to the design of the ventilation groove 602, the two cavities divided by the through hole 601 are communicated up and down. The ventilation grooves 602 are provided at least two times, and the ventilation grooves 602 are provided at equal intervals outside the through holes 601 of the connection column 6. The ventilation groove 602 does not need to be too large during design, and the sliding of the plug 5 in the through hole 601 is not affected. Preferably, the ventilation groove 602 is provided on the outer side of the top end of the through hole 601, when the plug 5 moves in the middle of the through hole 601, the two divided cavities of the through hole 601 are not closed, and when the plug 5 is at the top end or the bottom end of the through hole 601, the two divided cavities of the through hole 601 are vertically communicated with each other. Here, the plug 5 is at the top end of the through hole 601, and when the pressing of the stationary plate 1 is stopped, the plug 5 is rapidly moved to the middle of the through hole 601 by the repulsive force of the spring 2 and the reaction force of the disk body 7 as long as the pressing force is removed.
