[0011] A convex platform is arranged on the workbench, the side of the convex platform away from the workbench has a placing surface for placing a gasket, when one end of the pipe body is placed in the second placing groove, a part of the convex platform penetrates into the pipe body, one side of the gasket abuts against the placing surface, and the other side of the gasket abuts against the inner side wall of the pipe body.

[0012] By adopting the above technical solutions, the mat placing platform cooperates with the convex platform to clamp and position the parts of the towel rack, without manual participation. It only needs to thread the corresponding threaded rod onto the foot pad from above the mat placing platform, which improves the installation efficiency of the towel rack.

[0013] Optionally, the clamping component further includes a positioning plate arranged on the workbench, the mat placing platform and the convex platform are both arranged on the positioning plate, there are fixing holes on the positioning plate, and there are positioning blocks arranged on the workbench and passing through the fixing holes, and the number of the positioning blocks is several and arranged along the length direction of the workbench.

[0014] By adopting the above technical solutions, the positioning plate cooperates with the positioning blocks to install the clamping component on the workbench, and the number of the positioning blocks is several and arranged along the length direction, so that when the positioning plate cooperates with different positioning blocks, the distance between the two clamping components is different, thereby adapting to towel racks of different sizes and improving the adaptability of the positioning tooling.

[0015] Optionally, the mat placing platform includes:

[0016] A fixed part arranged on the workbench; and

[0017] A movable part arranged on the workbench and approaching or separating from the fixed part, and the fixed part and the movable part cooperate to form the first placing groove, the mounting holes and the second placing groove.

[0018] By adopting the above technical solutions, the mat placing platform is divided into two parts, so that the assembled towel rack can be taken out from the separation position of the fixed part and the movable part, which improves the taking-out efficiency of the towel rack.

[0019] Optionally, it further includes a control component, the control component includes a first air cylinder arranged on the positioning plate, the piston rod of the first air cylinder faces the fixed part, and the movable part is arranged on the piston rod of the first air cylinder.

[0020] By adopting the above technical solution, the setting of the first cylinder enables the movable part to move without manual operation, improving the moving efficiency of the movable part.

[0027] Optionally, a second abutting block is disposed on the boss and passes through the pipe body and abuts against the end face of the gasket.

[0028] By adopting the above technical solution, on the one hand, during the movement of the gasket, it will be rubbed by the inner side wall of the pipe body and move. The second abutting block abuts against the gasket, thereby preventing the gasket from moving during the movement, so that the gasket finally aligns with the support feet, improving the efficiency of the gasket moving to the aligned state. On the other hand, when the threaded rod is threadedly connected to the gasket, the gasket is not easily rotated due to abutting against the second abutting block, improving the installation stability of the gasket.

[0029] Optionally, an avoidance groove for avoiding the threaded rod passing through the gasket is disposed on the boss, and the avoidance groove penetrates through one side of the boss close to the middle of the pipe body.

[0030] By adopting the above technical solution, due to the provision of the avoidance groove, when the threaded rod moves towards the pipe body, it will not interfere with the boss.

The clamping assembly 5 includes a positioning plate 51, a pad 52 and a boss 53. The positioning plate 51 abuts against the workbench 4, and has a fixing hole 511 on the positioning plate 51. The workbench 4 is fixedly connected with a positioning block 41. The number of the positioning blocks 41 is several and they are arranged along the length direction of the workbench 4. One of the positioning blocks 41 is inserted into the fixing hole 511 to position the positioning plate 51. Here, the positioning block 41 has a T-shaped shape, and the fixing hole 511 and the positioning block 41 are adapted shapes, so that the positioning block 41 will not rotate on the plane of the workbench 4 after being inserted into the fixing hole 511. In other embodiments, the positioning block 41 may also be other shapes that can restrain the rotation of the positioning plate 51. The remaining parts of the clamping assembly 5 except the positioning plate 51 are all mounted on the positioning plate 51 , so that the entire clamping assembly 5 can adapt to pipe bodies 1 of different lengths due to different positioning blocks 41 and different spacings between two clamping assemblies 5 .

[0044] Reference Figure 3 The pad placement platform 52 includes a fixed portion 521 and a movable portion 522. The fixed portion 521 is fixedly connected to the positioning plate 51, and the movable portion 522 is movably connected to the positioning plate 51. The fixed portion 521 and the movable portion 522 cooperate to form a first placement groove 523. The first placement groove 523 is located on a side of the pad placement platform 52 away from the positioning plate 51 for placing the foot pad 3. A fixing pin 526 is fixedly connected to a side of the first placement groove 523 away from the movable portion 522 to fix the placed foot pad 3 to prevent it from being separated from the first placement groove 523 before installation is completed.

[0045] Reference Figure 3, the fixed part 521 and the movable part 522 cooperate to form a mounting hole 524 for the support leg 2 to pass through.
