Then the user pulls the pressure plate to slide on the T-shaped handle to separate the pressure plate from the outer wall of the hollow disk and the round tube. Then the user turns the T-shaped handle to drive the rotating inner gear ring to rotate counterclockwise. Under the action of the rotating gear, the four rotating gears are driven to move toward the center of the hollow disk, driving the four grinding rollers to contact the outer wall of the street light pole. Then release the pressure plate so that the pressure plate contacts the outer wall of the hollow disk and the round tube again, and fixes the four grinding rollers that contact the outer wall of the street light pole. When the four rotating gears all move toward the center of the hollow disk, the four V-shaped hinged rods are driven to fold and slide in the limiting slide grooves, and the diamond-shaped folding rods are driven to fold; S2: At this time, the motor drives the driving gear to rotate, driving the transmission gear to rotate, so that the round tube and hollow disk inside the transmission gear rotate to drive four grinding rollers to grind the outer wall of the street lamp pole, and during the rotation of the transmission gear, the driven gear on the right end face of the hollow disk rolls on the inner side of the fixed inner gear ring, and the cylindrical rod is driven to rotate through the driven gear, thereby driving the grinding rollers that perform circular motion to rotate; S3: When the left end of the street light pole moves and hits the baffle, the cylinder extends to drive the impact bearing to move right so that its outer ring hits the hollow deflection rod, and the hollow deflection rod is deflected to squeeze the sliding bearing to slide left in the right annular groove, pushing the four push plates to move left at the same time, and cooperating with the deflection plate to drive the four fan-shaped cutting blades to expand and slide on the left end face of the left annular groove, and the four fan-shaped cutting blades follow the rotation of the grinding roller and make circumferential rotation motion, thereby cutting the street light pole.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the street light pole is placed on two lifting support frames, and the left end of the street light pole is moved between four grinding rollers. Then the user pulls the pressure plate to slide on the T-shaped handle to separate the pressure plate from the hollow disk and the outer wall of the round tube. Then the user rotates the T-shaped handle to drive the rotating inner gear ring to rotate counterclockwise. Under the action of the rotating gear, the four rotating gears are driven to move toward the center of the hollow disk, driving the four grinding rollers to contact the outer wall of the street light pole, so as to facilitate the grinding of street light poles with different diameters.

Then, the user rotates the T-shaped handle (68) to drive the rotating inner gear ring (69) to rotate counterclockwise. Under the action of the rotating gear (610), the four rotating gears (610) are driven to move toward the center of the hollow disk (62), driving the four grinding rollers (614) to contact the outer wall of the street light pole. Then, the pressure plate (681) is released, so that the pressure plate (681) contacts the outer wall of the hollow disk (62) and the round tube (66) again, and the four grinding rollers (614) contacting the outer wall of the street light pole are fixed. When the four rotating gears (610) all move toward the center of the hollow disk (62), the four V-shaped hinged rods (616) are driven to fold and slide in the limiting sliding grooves (618), and the diamond-shaped folding rods (620) are driven to fold; S2: At this time, the motor (65) drives the driving gear (64) to rotate, driving the transmission gear (63) to rotate, so that the circular tube (66) and the hollow disk (62) inside the transmission gear (63) rotate and drive the four grinding rollers (614) to grind the outer wall of the street lamp pole. In addition, during the rotation of the transmission gear (63), the driven gear (622) on the right end surface of the hollow disk (62) rolls on the inner side of the fixed inner gear ring (5), and drives the cylindrical rod (621) to rotate through the driven gear (622), thereby driving the grinding rollers (614) that perform circular motion to rotate. S3: When the left end of the street light pole moves and contacts the baffle (2), the cylinder (8) extends to drive the contact bearing (9) to move rightward so that its outer ring contacts the hollow deflection rod (77), and the hollow deflection rod (77) is deflected to squeeze the sliding bearing (72) to slide leftward in the right annular groove (71), thereby pushing the four push plates (73) to move leftward at the same time, and cooperating with the deflection plate (74) to drive the four fan-shaped cutting blades (75) to expand and slide on the left end surface of the left annular groove (71), and the four fan-shaped cutting blades (75) follow the grinding roller (614) to rotate and make a circumferential rotation motion, thereby cutting the street light pole.
