Figure 1 and Figure 2 When the first oblique iron 107 slides along the first chute 112, the second oblique iron 108 will be lifted or moved down under the guidance of the second chute 114, and the pad 109 on the second oblique iron 108 will rise or fall accordingly.
[0033] In some embodiments of the present invention, a handle 117 is provided at one end of the first oblique iron 107 in the sliding direction of the first oblique iron 107. Figure 2 One end of the first baffle and the second baffle 111 is provided with an end plate 116, one end of the handle 117 is connected to the first oblique iron 107 through a handle 117 bracket provided on the first oblique iron 107, and the other end of the handle 117 passes through the end plate 116 and is connected to a pull ring for easy operation.
[0034] In some embodiments of the present invention, two first connecting beams 118 are provided on the side of the rear frame assembly 102 close to the front frame 101. The length direction of the first connecting beams 118 extends in the direction of the front frame 101.
