A tool 11 is detachably connected to the left end of the shell 1, and the tool 11 is driven to move up and down by the driving mechanism.

[0026] When the utility model is in use, the vertical movement of the supporting roller 3 and the lateral movement of the clamping roller 7 can be applied to pipes of different diameters, thereby achieving the purpose of grooves for pipes of different diameters;

[0027] In order to enable the L-shaped plate 6 to drive the flat plate 2, the flat plate 2 is symmetrically provided with first inclined blocks 12 at the front and rear ends, and the end faces of the two first inclined blocks 12 at the opposite ends are in an inverted eight shape.

[0030] The reset mechanism includes a reset spring 15. U-shaped plates 16 with openings facing downward are respectively provided at the left and right ends of the housing 1. The reset spring 15 is located between the upper end of the U-shaped plate 16 and the flat plate 2. The reset spring 15 drives the first inclined block 12 through the flat plate 2 to always press the second inclined block 13.

[0031] The guide mechanism includes a guide rail 17 arranged in the front-rear direction, and a slider 18 is slidably connected to the guide rail 17. The slider 18 is fixedly connected to the L-shaped plate 6 on its corresponding side, so that the L-shaped plate 6 can only slide forward and backward along the track of the guide rail 17 through the slider 18.

[0032] The driving mechanism includes a base 19, on which a mounting plate 20 is vertically slidably connected, and the mounting plate 20 is detachably connected to the tool 11.

[0033] In this embodiment, a first hand wheel 22 is coaxially disposed at the lower end of the screw rod 21 to facilitate the staff to rotate the screw rod 21 .

[0034] In order to facilitate the staff to rotate the rotating shaft 8, a worm wheel 23 is coaxially provided at the lower end of the rotating shaft 8, and a worm 24 located below the turntable 9 and axially arranged front and back is rotatably connected in the outer shell 1.

[0039] When the L-shaped plate 6 moves, it will also drive the Z-shaped plates 14 at the left and right ends to move, and the Z-shaped plate 14 will drive the second inclined block 13 to move. Since the second inclined block 13 fits the inclined surface on the first inclined block 12, and the inclined surfaces on the two first inclined blocks 12 are in an inverted eight-shaped shape, the second inclined block 13 will squeeze the first inclined block 12 upward when it moves, and the first inclined block 12 will drive the flat plate 2 to move upward along the vertical portion of the U-shaped plate 16, and the flat plate 2 will drive the supporting roller 3 to move upward, and the multiple supporting rollers 3 will jointly drive the pipeline to move upward, and at the same time, the flat plate 2 will squeeze the reset spring 15 when it moves upward;

[0040] When the clamping rollers 7 on the front and rear sides are in contact with the outer edge of the pipe, the outer surface of the pipe fits with the outer surface of the clamping rollers 7, and the motor 4 is started at this time, the motor 4 drives the right support roller 3 to rotate, the support roller 3 drives the pipe to rotate, and the pipe drives the multiple clamping rollers 7 to rotate, that is, the pipe can rotate with the clamping rollers 7 and the support rollers 3 while being clamped;

[0041] The first hand wheel 22 is rotated clockwise, and the first hand wheel 22 drives the screw rod 21 to rotate on the base 19, and the screw rod 21 drives the mounting plate 20 to move upward, and the mounting plate 20 drives the tool 11 to move upward.
