[0008] like Figure 1 , Figure 2 As shown, it comprises a base 1 and a rotating trolley 2, the base 1 is provided with an axially horizontal arc slideway 11, the rotating trolley 2 is rotatably mounted with a plurality of slideway wheels 21 that match the arc slideway 11, the rotating trolley 2 is mounted on the arc slideway 11 of the base 1 through the slideway wheels 21, and reciprocates along the circumference of the arc slideway 11 on the base 1, a locking mechanism 3 is provided between the base 1 and the rotating trolley 2, and the locking mechanism 3 comprises a locking hook plate 31, a spring 32, a horizontal position locking block 33 and a vertical position locking block 34. 4, the locking hook plate 31 is hinged on the base 1 through a pin shaft 35, a spring 32 is arranged between the base 1 and the locking hook plate 31, and plays a role in resetting the locking hook plate 31, a horizontal locking block 33 and a vertical locking block 34 are respectively arranged on the rotating trolley 2, the locking hook plate 31 is provided with a horizontal hook 36 and a vertical hook 37 respectively matched with the horizontal locking block 33 and the vertical locking block 34, and the locking hook plate 31 is also provided with a pedal 38 for controlling the locking hook plate 31 to rotate and release the rotating trolley 2.

[0009] Two axially horizontal arc slideways 11 are arranged side by side on the base 1, and two rows of slideway wheels 21 are arranged along the circumference of the arc slideway 11 on the rotating trolley 2, which are respectively matched with the two arc slideways 11. Wheel grooves matching with the arc slideway 11 are respectively arranged on the circumference of each slideway wheel 21.

[0010] The frame of the rotating trolley 2 is L-shaped along the axial direction of the arc-shaped slideway 11, and the frame of the rotating trolley 2 is composed of a chuck vertical seat plate 22 and a chuck horizontal seat plate 23. One side of the chuck vertical seat plate 22 is vertically connected to one side of the chuck horizontal seat plate 23, and the chuck horizontal seat plate 23 is connected to the chuck vertical seat plate 22. The opposite side is provided with a trolley handle 24 for turning over the rotating trolley 2. The trolley handle 24 is a U-shaped frame with two free ends respectively connected to the chuck horizontal seat plate 23.

[0011] The horizontal locking block 33 is arranged on the side where the horizontal seat plate 23 of the chuck is connected to the trolley handle 24, and the vertical locking block 34 is arranged on the side where the horizontal seat plate 23 of the chuck is connected to the vertical seat plate 22 of the chuck.
