[0038] It should be noted that one end of the buffer spring 43 is fixed to one side of the slider 42, and the other end is fixed to the inner side of the slide groove 41; when the pressure piece applies pressure to cause the movable plate 2 to move downward, the two sides of the movable plate 2 will be together with the hinged movable rod 44, driving the slider 42 hinged at one end of the movable rod 44 to slide on the inner side of the slide groove 41, thereby squeezing the buffer spring 43 on one side of the slider 42, which can be pulled and limited on both sides of the movable plate 2, and provide buffering, thereby preventing displacement and improving stability.

[0039] like Figure 4 As shown, the card-connecting assembly includes: a movable groove 6 opened on the front side of the opening and closing door 5, a card-connecting groove 61 opened on the side of the device body 1 facing the movable groove 6, and a lever 62 slidably connected to the inner side of the movable groove 6; a return spring 63 is arranged between one side of the lever 62 and the inner side of the movable groove 6, and a card block 64 is fixed on the side of the lever 62 facing the card slot 61, and the card block 64 is card-connected to the inner side of the card slot 61.

[0041] When the utility model is used, adaptive adjustment is first performed according to the pressure applied, and the selector bar 62 is moved to slide on the inner side of the movable groove 6, and the reset spring 63 on the inner side of the movable groove 6 is squeezed, so that the block 64 on one side of the selector bar 62 is disengaged from the inner side of the clamping groove 61, and the clamping limit of the opening and closing door 5 can be released, and then the opening and closing door 5 can be opened, so that the operator can operate the inside of the equipment body 1, and the adjusting bolt 23 is turned to make the squeezing plate 24 press down the first shock-absorbing spring 25, and at the same time, the telescopic rod 22 will play a role in limiting the length, so that the buffering and shock-absorbing force of the first shock-absorbing spring 25 reaches the required requirement.

At the same time, after the downward force acts on the movable plate 2, the movable plate 2 will move downward through the adjusting bolt 23 to drive the extrusion plate 24 inside the fixed cylinder 21 to squeeze the first shock-absorbing spring 25 downward, which can further play a role in shock absorption and buffering.
