At the same time, the rotating portion 223 can rotate with the supporting portion 232 and move downwardly close to the fixing base 21. Under the action of the second fixing pin 25, the rotating portion 223 drives the supporting portion 232 to move downwardly close to the fixing base 21. The supporting portion 232 rotates relative to the fixing base 21. At the same time, the positioning portion 231 is lifted upwardly, which facilitates the placement of the pipe 100 on the positioning plate 11. After the pipe 100 is placed on the positioning plate 11, the pressing portion 221 is pressed. The connecting portion 222 rotates relative to the fixing base 21 and drives the supporting portion 232 to rotate, so that the positioning portion 231 is pressed against the end face of the pipe 100. The pipe 100 can be fixed relative to the positioning plate 11.

The pressing piece 27 is provided as a pressing plate. The locking piece 28 is provided as a combination of a locking bolt and a screw rod. After the pressing piece 27 is in contact with the end face of the pipe 100, the pressing piece 27 is rotated according to the shape and structure of the end face of the pipe 100, so that the pressing piece 27 can be in surface-to-surface contact with the end face of the pipe 100, that is, the pressing piece 27 is completely pressed against the end face of the pipe 100. Then, the locking piece 28 is screwed, and the locking piece 28 abuts against the end face of the positioning piece 23, so that the pressing piece 27 is fixed relative to the positioning piece 23 and firmly installed and not easy to loosen.

[0039] Further, with continuous reference to Figure 2 The positioning assembly 2 further comprises a sliding piece 29. The sliding piece 29 and the pressing piece 27 are located on the two sides of the positioning piece 23, respectively. The adjusting hole is in a waist-shaped hole structure. The locking piece 28 penetrates the through hole of the sliding piece 29 and the adjusting hole in sequence and is connected to the pressing piece 27. The locking piece 28 can slide along the length direction of the adjusting hole to adjust the position of the pressing piece 27 relative to the positioning piece 23. The sliding piece 29 is provided as a sliding sleeve. According to the specific position of the pipe 100 on the positioning plate 11, the sliding piece 29 slides along the length direction of the adjusting hole, so that the pressing piece 27 can slide above the end face of the pipe 100 relative to the positioning piece 23. Then, the pressing piece 27 can be vertically moved close to and pressed against the end face of the pipe 100. The locking piece 28 is screwed, and the locking piece 28 abuts against the end face of the positioning piece 23, so that the pressing piece 27 is fixed relative to the positioning piece 23. It is ensured that the pressing piece 27 can be stably pressed against the end face of the pipe 100, and the pipe 100 is prevented from being twisted and scrapped due to unfirm clamping during machining.

[0040] Further, with reference to Figure 1 The bicycle pipe tool clamp further comprises a connecting piece. The base 1 is provided with a mounting hole 12. The connecting piece penetrates the mounting hole 12 and is fixedly connected to the workbench. The connecting piece is provided as a bolt.
