[0023] A support mechanism for supporting the support frame 12 during movement is provided on one side of the top plate 7 close to the support frame 12. The support mechanism includes a plurality of equally spaced sliding frames 11 fixedly connected to one side of the support frame 12. The plurality of sliding frames 11 are all slidably connected to the top plate 7.

[0024] A lifting frame 15 is fixedly connected to both sides of the swing frame 5, and a connecting base 16 is rotatably connected to one side of the lifting frame 15.
