The two springs 206 are respectively sleeved on the outer sides of the two L-shaped round rods 201. Two chutes 5 are symmetrically provided at the bottom of the mounting frame 1. The two sliding plates 202 are respectively slidably connected with the two chutes 5. Horizontal plates 203 are fixedly installed on the sides of the two sliding plates 202 close to each other. The two horizontal plates 203 are both located below the mounting frame 1. The small hole cutter 4 is located between the two horizontal plates 203. Arc-shaped grooves are provided on the sides of the two horizontal plates 203 close to each other. Bristles 204 are provided in the two arc-shaped grooves. A cylinder 208 is fixedly installed at the bottom of the mounting plate 6. A lifting plate 209 is fixedly installed at the bottom end of the cylinder 208. Two movable rods 2010 are symmetrically and rotatably connected to the outside of the lifting plate 209. Sliders 205 are movably sleeved on the outer sides of the two L-shaped round rods 201. The sides of the two sliders 205 away from each other are respectively attached to the sides of the two sliding plates 202 close to each other. The ends of the two movable rods 2010 away from the lifting plate 209 are respectively rotatably connected to the tops of the two sliders 205. Two upright columns 207 are symmetrically and fixedly connected between the bottom of the mounting plate 6 and the inner bottom wall of the mounting frame 1. The lifting plate 209 is movably sleeved on the outer sides of the two upright columns 207;

[0025] In the initial state, the mutually remote sides of the two sliders 205 are respectively in contact with the mutually close sides of the two slide plates 202, and the two springs 206 are both in a compressed state. First, start the air cylinder 208 to drive the lifting plate 209 to slide upward along the two columns 207, and drive the two sliders 205 to slide along the two L-shaped round rods 201 respectively through the two movable rods 2010, releasing the limiting effect on the two slide plates 202. At this time, the two springs 206 reset to drive the two slide plates 202 to slide along the two L-shaped round rods 201 respectively, and drive the two cross plates 203 to move to clamp the small-hole cutter 4. When the small-hole cutter 4 rises, the surface of the small-hole cutter 4 is cleaned by the two brush hairs 204. Finally, it is not necessary to disassemble and clean the small-hole cutter 4.

Then start the air cylinder 208 to drive the lifting plate 209 to slide downward along the two columns 207, drive the two sliders 205 to slide along the two L-shaped round rods 201 respectively through the two movable rods 2010, and push the two slide plates 202. At this time, the two springs 206 are both compressed, and the two cross plates 203 move away from each other. At the same time, the rotating small-hole cutter 4 descends for small-hole machining. When starting the air cylinder 208 to drive the lifting plate 209 to slide upward along the two columns 207, drive the two sliders 205 to approach each other. At this time, the two springs 206 reset to drive the two slide plates 202 to slide respectively. At this time, the two cross plates 203 approach each other until they clamp the small-hole cutter 4.
