[0034] In addition, the movable block 125 is mounted on the top of the second support rod 124 via a shaft; the abutting component is connected to the bottom of the inner side of the movable frame 123 and connected to the movable block 125; the outer side of the movable block 125 is provided with a third limiting groove; there are multiple movable blocks 125; the top ends of two support rods are mounted on the bottom of the movable block 125 via shafts; the abutting component drives the movable block 125 to move the second support rod 124, causing the bottom ends of the two second support rods 124 to move relative to or opposite to each other, thereby driving the block 121 to make precise horizontal position adjustments, thus driving the block 121 to move horizontally.

[0035] Finally, the adjusting block 126 is slidably connected to the outside of the moving block 125 and slidably connected to the inside of the moving frame 123; the second electric telescopic rod 127 is fixedly connected to the top of the moving frame 123, the output end of the second electric telescopic rod 127 is connected to the top of the adjusting block 126, the bottom end of the adjusting block 126 is provided with a third limiting groove, the top of the moving frame 123 is designed with a mounting hole, the second telescopic rod is located in the mounting hole of the moving frame 123, and the adjusting block 126 is driven to move inside the moving frame 123 through the second telescopic rod.
