[0025] like Figure 1-5 As shown, the synchronous drive mechanism includes a rotating disk 7 rotatably connected to the inside of the mounting disk 2, and sliding blocks 17 are fixedly connected with a sliding pin 9 at one end away from each other. Guide grooves 8 are opened at the corresponding sliding blocks 17 on the rotating disk 7, and the sliding pin 9 is slidably connected inside the guide groove 8. By rotating the rotating disk 7, multiple fixed blocks 6 can be driven to move synchronously at the same time, making the operation of fixing the pipe fittings simple and quick.
[0026] like Figure 1-5 As shown, three sliding grooves 15 are provided and evenly distributed around the axis of the mounting plate 2. At the same time, the pipe is clamped by three fixing blocks 6. The three-point clamping is stable and the pipe clamping is more stable.
[0027] like Figure 1-5 As shown, the fixing block 6 is an arc-shaped block, and the arc-shaped surface is an inner concave surface, which can fit the surface of the pipe fitting to improve the clamping stability.
[0028] like Figure 1-5 As shown, the arc surface of the fixing block 6 is provided with a plurality of uniform rectangular grooves 14, which can increase the contact friction with the surface of the pipe fitting and further enhance the clamping stability.
