[0043] This embodiment has the following advantages:

[0045] The upper clamping device, the middle clamping device and the lower clamping device are all located at the column 12, and the upper clamping device, the middle clamping device, the lower clamping device and the column 12 correspond one to one, so that the stability of the upper support device, the middle clamping device and the lower clamping device can be stably supported by the column 12, effectively reducing the torque that the upper support frame 21, the middle support frame 41 and the lower support frame 31 need to bear, and can ensure the stability of the overall structure, so that the tower coil clamp can bear the weight of 2 goods at the same time.

[0046] The two upper support frames 21, the middle support frame 41 and the lower support frame 31 are fixed to the two columns 12 respectively, so that the upper support frame 21, the middle support frame 41, the lower support frame 31 and the columns 12 are built into a multi-point connected frame structure, which effectively improves the structural stability of the tower coil clamp.

[0047] The two upper clamping mechanisms are driven respectively by the two upper driving mechanisms, so that the two upper clamping mechanisms can be driven respectively to clamp the goods, thereby realizing the function of clamping the goods respectively.

[0048] The upper driving member 23 drives the upper screw rod 24 to rotate.

[0051] The middle clamping arm 42 is rotated on the middle support frame 41 to provide a supporting force to the middle of the cargo through the middle clamping arm 42, thereby improving the stability of the cargo.

[0052] During the rotation of the lower clamping arm 32 , the middle clamping arm 42 is driven to rotate via the linkage rod 43 , thereby realizing the function of driving the middle clamping arm 42 to rotate on the middle support frame 41 .

[0053] The middle clamp arm 42 is close to the lower clamp arm 32, which can make the center of gravity of the tower coil clamp lower, thereby improving the overall stability.
