The working principle is as follows: when chamfering edges of the solid wood furniture after the solid wood furniture is assembled, firstly, the plate is inserted between the disc 7 and the limiting ring 10 when the device is moved, meanwhile, the ball 11 above the device is contacted with the top side of the solid wood plate, then, the limiting operation of the device when the device is static can be temporarily finished by holding the driver 2 by hand, then, the driver 2 is intermittently started, meanwhile, the chamfering device 1 is moved into the plate, the rotating tool bit 3 grinds the edges of the contacted plate into a fillet until the positioning bearing 9 is contacted with the edges of the solid wood plate, and the intermittent starting of the driver 2 is stopped;

then the other hand holds the net drum 53 and continuously starts the driver 2, at this time, due to the interference between the hexagonal ring 46 and the hexagonal groove 44, the threaded shaft 411 cannot idle in the sleeve 43, the net drum 53 is limited by the hand so that the net plate 51 cannot rotate, meanwhile, due to the rotation of the round rod 8, the inner wall of the threaded groove 42 and the threaded shaft 411 are in interference, the threaded shaft 411 is pulled to retract into the threaded groove 42, due to the pushing of the air bag 47 to the hexagonal ring 46, the threaded rod 41 can firstly pull the net plate 51 and the limiting ring 10 to move upwards, after the lower ball 11 is contacted with the solid wood furniture plate, due to the interference between the limiting ring 10 and the plate, the net ring cannot continue to move upwards, at this time, the hexagonal ring 46 presses and enables the air bag 47 to shrink and deform, and then the threaded rod 41 slides upwards in the sleeve 43;

in the process that the threaded rod 41 slides upwards in the sleeve 43, the distance between the pull ring 68 and the limit ring 10 is increased, and then a part of the pull rope 69 is pulled out from the limit plate, so that the piston plate 67 of the liquid storage tank 65 moves towards the direction of the screen plate 51, the filling liquid on one side of the piston plate 67 is pressed into the sliding groove 63, and then the positioning rod 64 is pushed outwards from the sliding groove 63, so that the hemispherical end of the positioning rod 64 is inserted into the corresponding hemispherical groove 62, and therefore the space between the disc 7 and the limit ring 10 is temporarily kept stable through mutual interference among the guide rod 61, the limit ring 10, the positioning rod 64 and the inner wall of the hemispherical groove 62;

after the hexagonal ring 46 moves to the circular groove 45, the threaded rod 41 idles and drives the impeller 52 to rotate, gas in the net cylinder 53 is pushed out to the lower part of the net cylinder 53, and outside gas is sucked from the net plate 51 to supplement to form directional gas flow, meanwhile, as the driver 2 drives the circular rod 8 to rotate at high speed, the threaded rod 41 still receives a certain torsion, and the positioning rod 64 is temporarily and stably positioned in the corresponding hemispherical groove 62 by matching with the friction force generated by the collision between the threaded shaft 411 and the inner wall of the threaded groove 42 to offset the thrust of the air bag 47 on the hexagonal ring 46 and the thrust of the spring 610 on the piston plate 67, and the position of the threaded shaft 411 in the threaded groove 42 is temporarily and stably kept, so that the distance between the limiting ring 10 and the disc 7 is kept stable, and at the moment, the driver 2 drives, the circular rod 8, the cutter head 3, the threaded rod 41, the sleeve 43, the net plate 51 and the net cylinder 53 to continuously rotate;

at the moment, the chamfering device 1 is pushed along a plate needing chamfering, the rotating cutter head 3 finishes chamfering and trimming treatment of the plate along the edge needing chamfering of the solid wood furniture plate, the cutter head 3 is difficult to generate a certain inclination angle due to the three-direction limiting of the limiting ring 10, the disc 7 and the limiting bearing, fine sawdust produced by grinding the plate by the cutter head 3 moves along with gas and enters the net cylinder 53 through the hole of the net plate 51, the net cylinder 53 is intercepted in the net cylinder 53 for storage, and the net cylinder 53 can be screwed out of the net plate 51 for treatment of the sawdust in the net cylinder 53 after the use of the chamfering device 1 is finished;

after chamfering of the solid wood furniture board is finished, the driver 2 is controlled to rotate reversely, according to the fact that the inner wall of the thread groove 42 is in mutual interference with the thread shaft 411, the rotating round rod 8 has the tendency of pushing the thread rod 41 downwards, the air bag 47 is matched with pushing of the hexagonal ring 46, and when the spring 610 pushes the piston plate 67, the thread rod 41 is pulled downwards through the pull rope 69, so that the hexagonal ring 46 moves towards the hexagonal groove 44, meanwhile, the thread rod 41 rotates along with the round rod 8, when the hexagonal ring 46 is aligned with the hexagonal groove 44, the bottom of the hexagonal ring 46 is inserted into the hexagonal groove 44, after the bottom of the hexagonal groove 44 is inserted into the hexagonal groove 44, due to the interference between the inner wall of the hexagonal groove 44 and the hexagonal ring 46, the thread rod 41 cannot rotate continuously, the downward pushing force of the thread groove 42 on the thread rod 41 is further increased, the hexagonal ring 46 is gradually inserted into the hexagonal groove 44 until the hexagonal ring 46 is in contact with the inner bottom wall of the hexagonal groove 44, and the thread rod 41 cannot slide downwards in the sleeve 43;

in the process that the threaded rod 41 moves downwards in the sleeve 43, the pulling state of the pulling rope 69 by the pulling ring 68 is released, the pulling limiting state of the piston plate 67 by the pulling rope 69 is released, the piston plate 67 is pushed to reset by the spring 610, then the filling liquid on one side of the positioning rod 64 is sucked into the liquid storage tank 65 by the connecting hole 66 on one side, the filling liquid on the other side of the piston plate 67 is pushed into the other side of the positioning rod 64 by the connecting hole 66 on the other side, the positioning rod 64 is pushed to retract into the sliding groove 63 by different pressures on two sides of the positioning rod 64, the collision between the positioning rod 64 and the inner wall of the hemispherical groove 62 is released, the clamping state between the limiting ring 10 and the guide rod 61 is released, the limiting state of the distance between the limiting ring 10 and the disc 7 is released, at the moment, the threaded rod 41 which is discharged from the threaded groove 42 pushes the limiting ring 10 to be far away from the plate, the limiting state between the chamfering ring 10 and the plate 1 and the disc 7 is released, and the chamfering plate 1 can be directly pulled out from solid wood furniture.

Those not described in detail in this specification are within the skill of the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
