[0025] Specifically, the upper end of the tooth plate 68 is meshingly connected with a gear 67, and the gear 67 is fixedly connected with the end of the rotating rod 62 away from the mounting plate 61.
[0026] In the embodiment, by setting the tooth plate 68 and the gear 67, the mounting plate 61 at one end of the rotating rod 62 can be rotated by one hundred and eighty degrees, which reduces the difficulty of rotating the mounting plate 61 during use of the equipment, thereby reducing the difficulty of rotating the electric plate 71.
[0027] Specifically, one end of the tooth plate 68 close to the placing frame 2 is fixedly connected with a sliding plate 610, and one side of the placing frame 2 close to the tooth plate 68 is fixedly connected with a blocking plate 69, and the blocking plate 69 is arranged to limit the sliding plate 610.
[0028] Specifically, the blocking plate 69 is arranged at the lower end of the sliding plate 610, and the sliding plate 610 is slidingly connected on the upper surface of the blocking plate 69.
[0029] In the embodiment: the inside of the mounting plate 61 is provided with an auxiliary assembly 7, the auxiliary assembly 7 includes a support plate 76, the support plate 76 is fixedly connected to one end of the mounting plate 61 away from the rotating rod 62, the upper surface of the support plate 76 is fixedly connected with a positioning rod 72, the surface of the positioning rod 72 is sleeved with an electric plate 71, and the inside of the mounting plate 61 is provided with a pull hole 73.
[0030] In the embodiment: by setting the positioning rod 72, the electric plate 71 can be limited, which reduces the situation that the electric plate 71 is easily moved away from the surface of the support plate 76 and falls to the ground during use of the equipment.
[0031] Specifically, the inside of the pull hole 73 is slidably connected with a clamping plate 74, one end of the clamping plate 74 abuts against the upper surface of the electric plate 71, and the clamping plate 74 is arranged to facilitate limiting the electric plate 71.
