Be equipped with flexible strip 26 between the lower baffle 7, flexible strip 26 is inside to have spring 27, when conveniently installing the device, pulls the lower baffle 7 of one side, puts into the back with steel pipe 30, resets through spring 27 and makes another lower baffle 7 can laminate with steel pipe 30 voluntarily, simultaneously for two lower baffles 7 are in on the same horizontal line, maintain the stability of device.

Embodiment two:

as shown in fig. 8, the lower baffle 7 is provided with a clamping groove 24, and the upper baffle 15 is provided with a clamping strip 25 inserted into the clamping groove 24. When the upper baffle 15 and the lower baffle 7 are attached, as the polishing brush 8 in the interior continuously rotates, the lower baffle 7 may deflect to a certain extent due to friction with the polishing brush 8, the upper baffle 15 fixed above limits the lower baffle 7, the upper baffle 15 and the lower baffle 7 are reinforced by the clamping strips 25 and the clamping grooves 24, and the clamping strips 25 and the clamping grooves 24 enable the lower baffle 7 to be more stably placed in place.

Working principle: the buckle 5 is aligned with the through hole 4 on the bracket 2, and the screw 6 is inserted into the through hole 4, so that the buckle 5 and the bracket 2 are tightly attached. At this time, the lower baffle 7 close to the motor 3 side is clamped on the outer side of the bracket 2, the steel pipe 30 to be subjected to corrosion protection treatment is pushed into the bracket 2 from a position far away from the motor 3 side and is propped against the lower baffle 7 close to the motor 3 side, the position of the polishing brush 8 inside the steel pipe 30 is adjusted by adjusting one end of the polishing brush 8 far away from the motor 3 side, after adjustment is finished, the other lower baffle 7 is propped against the side surface of the steel pipe 30, and two sides of the steel pipe 30 are propped against the lower baffle 7. At this time, since the polishing brush 8 is fastened to the lower baffle 7, the polishing brush 8 and the steel pipe 30 are in concentric circle positions. The motor 3 is started, the motor 3 drives the rotating shaft 9 to rotate, the elliptical plate 10 rotates and is separated from the guide rod 11 above, the guide rod 11 falls down until falling to the bottom end of the sliding groove inside the sliding groove plate 12 under the influence of gravity, meanwhile, the guide rod 11 drives the connecting belt 13 to move downwards, the connecting belt 13 drives the upper baffle 15 to move downwards, the upper baffle 15 contacts with the lower baffle 7 below and is tightly attached to form a circular ring, and the polishing brush 8 is not easy to deviate when rotating in the steel pipe 30 and can stably polish the inner wall of the steel pipe 30 uniformly. The motor 3 drives the rotating shaft 9 to rotate, the elliptic plate 10 rotates and is separated from the guide rod 11 above, the guide rod 11 drives the connecting belt 13 to move downwards so as to drive the upper baffle 15 to move downwards, the upper baffle 15 contacts with the lower baffle 7 below and is tightly attached to form a circular ring, and the polishing brush 8 is not easy to deviate when rotating in the steel pipe 30 and can stably polish the inner wall of the steel pipe 30 uniformly. When the elliptical plate 10 rotates for a circle to return to the original position, the guide rod 11 is pushed by the elliptical plate 10 to move upwards, the guide rod 11 drives the connecting belt 13 to move upwards so as to enable the upper baffle 15 to move upwards, the lower baffle 7 of the upper baffle 15 is separated and returns to the original position, so that the steel pipe 30 which has finished polishing and corrosion prevention treatment is not affected by the upper baffle 15 and the lower baffle 7 any more, and the steel pipe 30 is convenient to separate from the device and replace a new steel pipe 30.
