[0027] As Figures 1 - 8 shown, all pipelines of the present invention adopt steel wire hoses with high strength and compression resistance; For the upper, middle and lower parts of the manual combination sleeve, they may not be tightened. Therefore, the sleeve group needs to be placed in the lower buckle frame 5, and is initially centered and fixed through the cooperation of the clamping plate 504 and the spring telescopic rod 503. Then, the lower buckle frame 5 is lifted, and the top part of the sleeve is moved between the fixed clamping block 802 and the movable clamping block 803. At this time, the rocker 808 is rotated to drive the rotation of the rotating sleeve 805, the rotating sleeve 805 drives the rotation of the hexagonal shaft 806, the hexagonal shaft 806 drives the rotation of the control screw rod 807, and the movable clamping block 803 is pushed close to the fixed clamping block 802 by using the control screw rod 807 to fix the upper end of the bolt sleeve.

[0030] Specific usage method and function of this embodiment: In the present invention, during use, place the sleeve group in the lower buckle 5, and initially center and fix it through the cooperation of the clamping plate 504 and the spring telescopic rod 503. Then raise the lower buckle 5, move the top part of the sleeve between the fixed clamping block 802 and the movable clamping block 803. At this time, rotate the rocker 808 to drive the rotating sleeve 805 to rotate. The rotating sleeve 805 drives the hexagonal shaft 806 to rotate, and the hexagonal shaft 806 drives the control screw 807 to rotate. Use the control screw 807 to push the movable clamping block 803 closer to the fixed clamping block 802 to fix the upper end of the bolt sleeve. At this time, directly manually control the handle cylinder 809 to rotate the twist lock 8 to rotate the sleeve as a whole clockwise for fixation; During this period, the electromagnetic valve 13 directly connected between the fuel tank 11 and the piston group 7 is opened; Then loosen the movable clamping block 803, continue to raise the lower buckle 5, move the middle part of the sleeve between the fixed clamping block 802 and the movable clamping block 803, and use the fixed clamping block 802 and the movable clamping block 803 to fix the middle part of the sleeve. Then close the electromagnetic valve 13 directly connected between the fuel tank 11 and the piston group 7, open the electromagnetic valve 13 between the hydraulic pump 9 and the fuel tank 11, input hydraulic oil using the hydraulic pump 9 to expand the piston group 7, apply pressure to the twist lock 8, and attempt to rotate the sleeve. A pressure sensor is provided inside the piston group 7 to monitor the pressure, determine whether the sleeve can withstand the torque at a specified pressure, and determine whether it is qualified. If there is no damage to the sleeve when the specified pressure is reached, it indicates that the product is qualified; By controlling the opening and closing of the electromagnetic valves 13 in each group, the hydraulic supply position can be controlled. When hydraulic oil is input into the third oil cylinder 501 to expand the lower clamping block 502, the bottom of the sleeve can be fixed. When hydraulic oil is input into the second oil cylinder 401 to expand the upper clamping block 402, the top of the sleeve can be fixed; By controlling the rotation direction of the oil pump motor 10, it is possible to choose to input or extract hydraulic oil using the hydraulic pump 9.
