In some embodiments, as shown in fig. 1-2, the supporting plate 2 includes a fixed plate 21 and a movable plate 22, the fixed plate 21 is connected to the base 1, and the movable plate 22 is slidably disposed on the base 1. Therefore, the distance between the two supporting plates 2 can be conveniently adjusted. Of course, in the embodiment of the present invention, the supporting plate 2 may include two movable plates 22. In addition, in the present invention, the movable plate 22 can slide relative to the base 1 in a plurality of ways. For example, in some embodiments, the movable plate 22 is attached to a nut that fits over a lead screw, and a hand wheel is provided at one end of the lead screw. Thus, when the operator rotates the handwheel, the movable plate 22 can slide relative to the base 1. For another example, in some embodiments, a sliding block is connected to the movable plate 22, and a sliding rail is provided on the base 1, so that an operator can push the sliding block to slide on the sliding rail, thereby enabling the movable plate 22 to slide relative to the base 1. Of course, the sliding structure of the movable plate 22 relative to the base 1 may be other structures, which are not illustrated herein.

In some specific embodiments, as shown in fig. 1-2, the supporting column 3 includes two clamping bodies 31 and two supporting bodies 32, the two clamping bodies 31 are respectively disposed on the fixed plate 21 and the movable plate 22, the clamping bodies 31 cooperate with the clamping assembly 4 to clamp the right flange 214 and the left flange 215, and an upper surface of the clamping body 31 abuts against a lower surface of the door panel 211. The two supporting bodies 32 are provided, the two clamping bodies 31 are respectively arranged on the fixed plate 21 and the movable plate 22, and the upper surface of the supporting body 32 is abutted against the lower surface of the door panel 211.
