[0022] The slider is driven backward by the arc-shaped stopper. When the slider slides to the rear side of the inner wall of the slide slot, the rear side of the slider contacts the vertical block of the L-shaped block, which resists the L-shaped block, causing the L-shaped block to move downward and squeeze the compression spring. At the same time, the arc-shaped stopper drives the slider to continue moving backward. When the upper side of the inner wall of the slot slides to the upper side of the vertical block of the L-shaped block, the vertical block of the L-shaped block moves up into the slot through the compression spring, and the arc-shaped stopper can be quickly fixed, thereby increasing the speed of fixing the arc-shaped stopper.

The top of the slider 303 is fixedly connected to the side of the arc-shaped stopper 301, and the slider 303 is moved toward the rear side of the sliding groove 302 to facilitate the sliding of the side of the arc-shaped stopper 301 to fit the side of the sliding groove 302.
[0032] See the attached drawings in the specification Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The shape of the slider 303 and the shape of the interior of the slide groove 302 are both T-shaped, and a slot 304 is provided at the bottom of the slider 303. The T-shaped slider 303 can slide vertically inside the T-shaped slide groove 302.
[0033] See the attached drawings in the specification Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The fixing member 5 includes an L-shaped block 501, the side of the L-shaped block 501 is slidably connected to the inside of the L-shaped groove 4, the lower side of the horizontal block of the L-shaped block 501 is fixedly connected to a compression spring 502, one end of the compression spring 502 is fixedly connected to the inside of the L-shaped groove 4, the upper side of the vertical block of the L-shaped block 501 extends to the inside of the slide groove 302 and is slidably connected to the inside of the slot 304, and the arc stopper 301 is conveniently fixed after the L-shaped block 501 moves to the inside of the slot 304.
[0034] See the attached drawings in the specification Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , limiting grooves 201 are provided on both sides of the inner wall of the placement slot 2, and the limiting strip 202 is slidably connected to the inside of the limiting groove 201. The side of the limiting strip 202 is fixedly connected to the side of the arc-shaped stopper 301. The limiting groove 201 and the limiting strip 202 facilitate the accurate installation of the arc-shaped stopper 301 inside the placement slot 2.
[0035] See the attached drawings in the specification Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The number of the arc-shaped stoppers 301 is six, and the material of the arc-shaped stoppers 301 is hard rubber, which has a certain hardness and cushioning property.
[0036] See the attached drawings in the specification Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The rear side of the slider 303 and the front side of the vertical block of the L-shaped block 501 are both rounded, and the side of the slider 303 contacts the upper side of the vertical block of the L-shaped block 501.
