The external clamping structure is fixed on the upper part of the slide block, and two sets of first stroke limit telescopic cylinders are installed on the inner side of the slide block. The front end of the first stroke limit telescopic cylinder is fixed to the lower part of the flip-over structure. The external clamping structure and the flip-over structure can move left and right in the horizontal direction.

[0006] Furthermore, the lower end face of the workbench is fixed with support legs on both the left and right sides, and a rear fixing plate is fixed to the rear side of the workbench, with the upper end of the rear fixing plate fixed to the bottom of the top plate.

[0007] Furthermore, the lower end face of the top plate is fixed with side fixing plates at both ends, and a second X-axis linear guide is fixed between the two sets of side fixing plates, and a slider is slidably connected on the second X-axis linear guide.

[0010] Furthermore, the inner side of the arc-shaped clamping plate is provided with an anti-slip inner layer, and the inner side of the anti-slip inner layer is provided with multiple sets of first anti-slip protrusions. The first anti-slip protrusions adopt a semi-circular arc-shaped protrusion structure, and both the anti-slip inner layer and the first anti-slip protrusions are made of silicone rubber.

[0011] Furthermore, the flip-over structure has a movable cavity in the middle, which is an arc-shaped movable cavity structure. Three sets of flipping rollers are installed inside the movable cavity. The outer ring surface of the flipping rollers is provided with a second anti-slip protrusion, and a rotating shaft is installed at the center of the flipping rollers.
