Both ends of the U-shaped rod 20 are sleeved with a pulling tube 13, and the pulling tube 13 can slide on the U-shaped rod 20. A pulling rod 14 is installed between the two pulling tubes 13, and the two ends of the pulling rod 14 are respectively connected to the two pulling tubes 13. The middle part of the pulling rod 14 is connected to the hydraulic column 16, and one end of the hydraulic column 16 is connected to the first piston 17.

The suction cups 23 of the two sets of hydraulic cut-off locks are respectively located on both sides of the positioning ball 3. The suction cups 23 of the two sets of hydraulic cut-off locks can respectively cooperate with the positioning ball 3 and the ball panel 8.

[0021] The pusher of the present invention can use the manual adjustment nut 9 to push the sliding locking ring 2 and the fixed locking ring 4 to clamp the positioning ball 3, so that the sliding locking ring 2 and the fixed locking ring 4 are locked in a position that can manually adjust the angle of the adjusting rod 1 and the adjusting rod 1 will not rotate uncontrollably after the adjustment is completed, which is convenient for the positioning of the adjusting rod 1 after adjustment. The hydraulic cut-off locker of the present invention can, after adjusting the ends of several adjusting rods 1 to positions that match several important points of the standard workpiece, drive the first piston 17 to move toward the inside of the main cylinder body 18 by manually pressing the pulling rod 14, thereby increasing the liquid pressure inside the sub-cylinder body 30, thereby pushing the suction cups 23 on both sides of the positioning ball 3 to cooperate and tighten the positioning ball 3, preventing the positioning ball 3 from easily rotating uncontrolled, thereby locking the angle of the adjusting rod 1. Furthermore, when the suction cups 23 on both sides of the positioning ball 3 cooperate to tighten the positioning ball 3, they can synchronously form a force toward the adjusting rod 1 on the locking rod 32, so that the locking rod 32 locks the adjusting rod 1 and the positioning ball 3, preventing the adjusting rod 1 from easily sliding uncontrolled inside the through hole 19, thereby further locking the end of the adjusting rod 1 at a position corresponding to the important point of the standard workpiece. When the two second pistons 31 push the two suction cups 23 to cooperate and tighten the positioning ball 3, the transmission rod 28 and the pulling rod 34 move relative to each other. At this time, the pulling rod 34 can pull the middle part of the suction cup 23 through the rope hole 26. At this time, the side of the suction cup 23 fits the surface of the ball panel 8 or the positioning ball 3. Under the pulling of the rope hole 26 on the middle part of the suction cup 23, a negative pressure can be formed inside the suction cup 23, thereby allowing the suction cup 23 to fit the contour of the ball panel 8 or the positioning ball 3 on the one hand, and allowing the suction cup 23 to use the negative pressure to cooperate more closely with the ball panel 8 or the positioning ball 3, further preventing the positioning ball 3 and the adjusting rod 1 from rotating uncontrolled. Figure 2 The two hydraulic cut-off lockers are in a locked state with respect to the positioning ball 3. At this time, Figure 2 The elastic rubber layer 35 at the end of the locking rod 32 is compressed, so that the adjusting rod 1 and the positioning ball 3 are in a locked state.
