One end of the locking hook 4 is hinged to the pressure rod 3. The other end of the locking hook 4 is connected to the hanging ear two 8.

[0027] The collar 9 is bolted to the bottom outer edge of the buffer hydraulic cylinder 5.

[0028] The buffer hydraulic cylinder 5 includes a cylinder barrel 51. A sealing cavity is provided in the cylinder barrel 51. An adjusting plug 52, a compression spring 53, and a buffer piston 54 are successively arranged in the upper part of the sealing cavity. The adjusting plug 52 is threadedly connected to the cylinder barrel 51. A piston push rod 55 is arranged in the lower part of the sealing cavity. The bottom end of the piston push rod 55 extends out of the cylinder barrel 51 and is hinged to a pressing block 56 outside the cylinder barrel 51 through a pin shaft. The bottom of the cylinder barrel 51 is sealed by a gland 57. Hydraulic oil 58 is injected into the sealing cavity. A pressure gauge 59 is connected to the outer wall of the cylinder barrel 51 of the sealing cavity. The top of the adjusting plug 52 is connected to a handle 60.

[0029] The wire passing die 2 is a symmetric split structure. A wire passing hole 21 is provided in the middle of the wire passing die.

[0030] One side of the collar 9 of the pressure rod 3 is connected to a seat plate 31, and the other side is connected to a support plate 32. The bottom of the seat plate 31 is hinged to the hanging ear one 7 through a pin shaft.

[0033] Hook the hook plate 13 of the locking hook 4 to the hinge shaft 10 to make the wire passing die 2 in a pre-compressed state. The wire rope 101 passes through the closed wire passing die 2. Rotate the handle 60. When the adjusting plug 52 is screwed in, the compression spring 53 is stressed, and the buffer piston 54 is pressed down, causing the pressure of the hydraulic system to change. At this time, the pressure gauge 59 intuitively displays the pressure value. Adjust the pressure to the production process range by rotating the handle 60.

[0034] When the diameter of the wire rope 101 is irregular during closing, an upward impact force will be generated when passing through the wire passing die 2. At this time, the buffer hydraulic cylinder 5 that presses the wire passing die 2 is stressed and rebounds. Due to the buffering effect of the buffer hydraulic cylinder 5, the hydraulic cylinder can be protected from damage due to the impact force, and the scratching of the wire passing die 2 on the wire rope 101 can be reduced, thereby improving the product quality.
