[0024] The specific operation is as follows: since there are two adjusting components 11, the lifting seat 1109 and the push rod 3 in the adjusting component 11 are fixedly connected, and the swing arm 6 is pushed upward by the push rod 3, so that the left and right swing arms 6 can respectively complete clockwise and counterclockwise rotations, so that the first locking cylinder 4 and the second locking cylinder 7 are close to each other, achieving the effect of stabilizing the pressure for pipes of different diameters.

[0025] like Figure 3 and Figure 4As shown, the adjustment component 11 includes a fixed seat 1101 and a slide groove 1102, and the top surface of the fixed seat 1101 is provided with the slide groove 1102, the adjustment component 11 also includes a sliding block 1103 and a first connecting rod 1104, and the sliding block 1103 is arranged in the slide groove 1102, and the top of the sliding block 1103 is connected to the first connecting rod 1104 through a rotating shaft, the adjustment component 11 also includes a second connecting rod 1105 and a screw nut 1106, and the middle part of the first connecting rod 1104 is connected to the second connecting rod 1105 through a rotating shaft, and one end of the second connecting rod 1105 A lead screw nut 1106 is connected via a rotating shaft, and the adjustment component 11 also includes a trapezoidal lead screw 1107, a hand crank 1108 and a lifting seat 1109, and the trapezoidal lead screw 1107 is connected to the inside of the lead screw nut 1106, the front end of the trapezoidal lead screw 1107 is connected to the hand crank 1108, and the lifting seat 1109 is provided at the end of the trapezoidal lead screw 1107 away from the hand crank 1108, and the end of the second connecting rod 1105 away from the lead screw nut 1106 is connected to the fixed seat 1101 via a rotating shaft, and the fixed seat 1101 and the lifting seat 1109 are parallel to each other.
