[0045] In the embodiment, the square frame comprises: two connecting plates 102, which are movably arranged on the side walls in the width direction of the first opening; an electric screw rod slide rail, which is movably arranged on one side wall in the length direction of the first opening, two ends of the electric screw rod slide rail are connected with one ends of the two connecting plates 102 on the same side respectively, and two elastic limiting blocks 105 are arranged on the side wall of the electric screw rod slide rail; a guide plate 104, which is movably arranged on the other side wall in the length direction of the first opening, two ends of the guide plate 104 are connected with the other ends of the two connecting plates 102 on the same side respectively, and two elastic limiting blocks 105 are arranged on the side wall of the guide plate 104; two fixed blocks are arranged on the side walls of the electric screw rod slide rail and the guide plate 104 respectively, and each fixed block is located between the two elastic limiting blocks 105 on the same side respectively.

[0046] The square frame is movably arranged at the first opening of the resin tank 101, and the square frame is limited in the side wall of the first opening of the resin tank 101 by arranging two elastic limiting blocks 105 on one side of the electric screw rod slide rail and the guide plate 104, wherein the electric screw rod slide rail and the guide plate 104 are arranged on the upper wall in the length direction of the first opening respectively, the two connecting plates 102 are arranged on the side walls in the width direction of the first opening respectively, the two connecting plates 102, the electric screw rod slide rail and the guide plate 104 form the square frame, and the two connecting plates 102 are used to limit the positions of the electric screw rod slide rail and the guide plate 104, so that the stability of the electric screw rod slide rail or the guide plate 104 arranged on the opening wall in the length direction of the first opening is improved.
