A groove is provided in the middle part of the upper side of the fixed splint 1.

[0032] Embodiment 2

[0033] Reference Figure 1-3 A limiting mechanism for limiting the rubber pad 3 is provided on the side where the two slide plates 10 are close to each other, and the limiting mechanism includes an insertion rod 14 and a slider 13.

The plurality of sliders 13 are slidably arranged inside the corresponding mounting grooves, and the longitudinal sections of the slide plates 10 and the mounting grooves are both rectangular.
