Two guide rods 22 are symmetrically slid through the middle part of the mounting plate 24, and the tops of the two guide rods 22 are fixedly connected to the top surface of the inner part of the box body 1.

[0025] During use of the lifting mechanism 2, the servo motor 21 is started, and the output end of the servo motor 21 drives the screw rod 23 to rotate, which then synchronously drives the No. 1 mounting plate 24 to move downward, and then synchronously drives the fixing rod 25 and the alternating reciprocating swing mechanism 3 to move downward.

[0026] See also Figure 1 、 Figure 2 and Figure 3 The alternating reciprocating swing mechanism 3 includes a driving component 31 and an execution component 32.
