A chute is provided on the skateboard 3, which is slidably and obliquely arranged on the skateboard 3, and the chute is inclined downward in a direction away from the retaining wall. The number of the chutes is at least two. At least two positioning rods slidably arranged inside the chute are fixedly installed on the side of the pushing block 331, and the positioning rods are slidably arranged inside the chute. Thus, the movement of the pushing block 331 can be guided.

[0050] Specifically, in this embodiment, the pushing block 331 is installed on the side of the support plate 31 close to the retaining wall. When the sliding plate 3 moves on the support seat 2 in the direction close to the retaining wall, when the pushing block 331 abuts against the retaining wall or the strip in front, it will move downward under the guidance of the chute, and drive the push rod 322 to move away from the retaining wall through the guidance of the first inclined surface and the second inclined surface. When the push rod 322 moves, it can drive the support plate 31 to flip, so as to realize the operation of placing the strip on the retaining wall.

[0051] Specifically, in this embodiment, when the support plate 31 flips to the vertical state, the support plate 31 can continue to push the strip in the direction close to the retaining wall. At this time, the pushing block 331 is located inside the sliding plate 3 and below a plurality of strips, and is limited inside the sliding plate 3 by the gravity of the strips. When the pushing block 331 disengages from the strip, it can drive the pushing block 331 to move upward under the action of the elastic member 332. And during the upward movement, the pushing block 331 can further push the strip in the direction close to the retaining wall.

The U-shaped plate 41 includes two parallel and spaced-apart clamping plates, and the retaining wall and the strips are located between the two clamping plates; the fastening member 42 is threadedly connected to the clamping plate closer to the retaining wall, and the end of the fastening member 42 abuts against the retaining wall. A pressing plate is fixedly connected between the two clamping plates, and the pressing plate is used to press against the tops of the plurality of strips. In use, the U-shaped plate 41 can be covered on the tops of the plurality of strips, so that the two clamping plates respectively abut against the outer sides of the strips on the side away from the retaining wall and the outer side of the retaining wall. Then, by tightening the fastening member 42, the plurality of strips can be tightened between the retaining wall and a single clamping plate. The structure is simple and the operation is convenient.

[0055] In some embodiments, the above-mentioned fastening member 42 can adopt the structure as shown in Figure 4 . Refer to Figure 4 . A wedge block 43 is rotatably arranged at the end of the fastening member 42, a guiding hole for accommodating the wedge block 43 is arranged on the outer side wall of the retaining wall, and the top surface of the wedge block 43 is inclined downward in a direction away from the fastening member 42.

The fixing plate 542 and the moving plate 543 are respectively arranged perpendicular to the baffle 541 and are located on the same side of the baffle 541. The fixing plate 542 is fixedly installed on the baffle 541, and the inner side surface of the retaining wall on the support base 2 is in the same plane as the side of the fixing plate 542 close to the moving plate 543. The moving plate 543 is installed on the baffle 541, and the moving plate 543 is slidably arranged on the baffle 541 along the direction of approaching or departing from the fixing plate 542. By moving the moving plate 543, the ends of multiple strips can be fixedly clamped between the moving plate 543 and the fixing plate 542.

[0060] Preferably, in this embodiment, an anti-slip pad is fixedly installed on the side of the moving plate 543 close to the fixing plate 542.

The tightening member 553 is a nut, and the tightening member 553 can be tightened against the outer side surface of the side plate so that a plurality of strips are tightened between the fixed plate 542 and the moving plate 543.

[0062] Specifically, in this embodiment, a slot for accommodating the guide plate 551 is recessed in the baffle 541. The guide plate 551 is provided with an inclined guide groove inside the slot.

Ensure the stability of the pulling force during the experiment.
