[0031] The first limiting frame 1 and the second limiting frame 5 are set opposite to each other; the first limiting frame 1 is fitted on the outside of one of the two supports on the same pad stone 9, and the second limiting frame 5 is fitted on the outside of the other of the two supports on the same pad stone 9; the first limiting frame 1 and the second limiting frame 5 form a semi-enclosed structure, covering and fixing the upper end of the pad stone 9.

[0032] A detachable connecting mechanism is detachably connected to the first limiting frame 1 and the second limiting frame 5 respectively, so as to adjust the relative distance between the first limiting frame 1 and the second limiting frame 5.

[0033] In this embodiment, a rubber buffer layer is provided between the first limiting frame 1 and the pad stone 9, and between the second limiting frame 5 and the pad stone 9.
