After the second oil cylinder 12 is filled, the hydraulic oil enters the first oil cylinder 10 through the oil pipe 8 on the side of the second oil cylinder 12, thereby pushing the piston 9 at the bottom of the first oil cylinder 10 to slide in the first oil cylinder 10, thereby pushing the top 11, so that the block 3 clamps the round rod 4, so that the profiling block 5 on the top can stably support the supported part 17. This device needs to be used in conjunction with the telescopic push rod. During use, the supported part 17 is positioned at three points by the contact end of the telescopic push rod and the inclined inner wall of the V-shaped groove 13.

[0029] like Figure 2As shown, a trumpet-shaped groove 14 is provided at the front side of the first oil cylinder 10 to improve the error tolerance of the plug 11 inserted into the trumpet-shaped groove 14 and reduce the difficulty of plugging the plug 11 into the trumpet-shaped groove 14 .

A profiling block 5 is fixedly connected to the top of the round rod 4, and the top of the profiling block 5 supports the supported member 17, thereby achieving the effect of firmly supporting the supported member 17.

[0037] The trumpet-shaped groove 14 is used to improve the tolerance of the insertion of the top head 11 into the trumpet-shaped groove 14 and reduce the difficulty of plugging the top head 11 into the trumpet-shaped groove 14. The function of the protrusion 19 is to reduce the distance between the first oil cylinder 10 and the piston 9, shorten the time for the piston 9 to act on the block 3, and thus fix the round rod 4 faster. The functions of the fixing ears 22 and the latch 21 are to facilitate the staff to disassemble and assemble the profiling block 5. Chamfers 20 are provided on both sides of the V-shaped groove 13 to prevent the edges and corners on both sides of the V-shaped groove 13 from contacting with the outer circumferential surface of the supported part 17, resulting in damage to the outer circumferential surface of the supported part 17, and to ensure the integrity of the outer surface of the supported part 17. A limiting opening 16 is provided at the bottom of the round rod 4 to prevent the round rod 4 from being ejected too much and detached from the hydraulic mechanism.
