The upper beam 13 and the lower beam 14 are connected with the rear end and the front end of the hydraulic cylinder 2, so that the hydraulic cylinder 2 is clamped and fixed between the upper beam 13 and the lower beam 14, and the clamping and fixing ensure that the plunger 21 of the hydraulic cylinder 2 can vertically extend downwards. Of course, the lower beam 14 clamps and fixes the front end of the hydraulic cylinder 2, and the extension and contraction of the plunger 21 of the hydraulic cylinder 2 should not be limited, that is, the lower beam 14 is only connected to the front end of the cylinder body of the hydraulic cylinder 2, and the extension and contraction direction of the plunger 21 is avoided, so that the plunger 21 of the hydraulic cylinder 2 can freely penetrate through the lower beam 14 and is not affected by the clamping.

The base 11 has a plate-like structure. The width of the base 11 in the left-right direction is slightly larger than the outer distance between two columns 12 which are arranged side by side (see fig. 1). The length of the base 11 in the front-back direction is greater than the thickness of the upright post 12 in the front-back direction and is also greater than the length of the wire core supporting plate 4 in the front-back direction. An inverted T-shaped matching structure is formed between the base 11 and two columns 12 which are spaced side by side in the front-back direction (see figure 2).
