A three-position cylinder 7 is arranged on the side of the seat plate 4, and a rack 701 is fixedly connected to the piston rod of the three-position cylinder 7. A gear 501 is fixedly connected to the end of each rotating shaft 5, and the gear 501 is meshed with the rack 701.

[0016] The rodless cylinder 2 is slidingly connected to the gantry 1, and the position of the rodless cylinder 2 can be adjusted to meet the pressing requirements of plastic pallets of different sizes. The rodless cylinder 2 can switch the position of the seat plate 4, so as to press-fit the anti-slip pad at different positions of the plastic pallet. The rodless cylinder 2 is fixedly connected to the gantry 1 by a locking screw.

[0017] The plurality of avoidance grooves 401 are distributed on the seat plate 4 in a linear array, and the plurality of rotation shafts 5 are distributed on the seat plate 4 in a linear array, and the rotation shafts 5 and the avoidance grooves 401 are perpendicular to each other.
