[0025] In the embodiment, the third limiting rod 8 can stabilize the lifting of the second limiting rod 6. The first transmission member 2 and the second transmission member 11 are gears. The first transmission member 2 is driven to rotate by the motor 3, and then the second transmission member 11 engaged with the first transmission member 2 is driven to rotate, and the first vertical column 10 is driven to rotate, and the conveyor 1 is driven to rotate. The rolling bodies of the bull-eye bearing 13 contact the upper surface of the disc 9. The bull-eye bearing 13 is a common rolling bearing made of steel rolling bodies and has high wear resistance, corrosion resistance, long service life and other advantages. The bull-eye bearing 13 is installed at the bottom of the second vertical column 12 to effectively reduce the friction between the second vertical column 12 and the disc 9, thereby preventing wear.
[0026] Please refer to Figures 1-4 A group of second electric push rods 14 are installed on the two sides of the conveyor 1.

Since the rolling body of the cow eye bearing 13 is in contact with the upper surface of the disc 9, the cow eye bearing 13 is a commonly used rolling bearing, which adopts steel rolling body and is made by precise machining, has the advantages of high wear resistance, corrosion resistance and long service life, etc. It is installed at the bottom of the second column 12, which can effectively reduce the friction between the second column 12 and the disc 9, thereby playing a role in preventing wear. By retracting the second electric push rod 14, the first clamping block 15 can be pulled down to clamp the blank and prevent the blank from falling off when the conveyor 1 rotates. One group of second clamping blocks 18 is connected to the opposite end of each group of slide rods 17, and the other group of second clamping blocks 18 is penetrated by the slide rods 17, and the two are slidingly connected. It can be seen that the two clamping members are slidingly connected and cooperate with each other to form a rectangular structure with adjustable length. The length of the clamping member can be adjusted according to the length of the blank, and then the fastening bolt 16 is tightened to lock the slide rod 17, so that the length adjustment of the clamping member is completed, and the blank is adapted, so that the blank can be clamped by the first clamping block 15 and the two groups of second clamping blocks 18.
