In still another embodiment of the present invention, the disc 61 may rotate along with the mounting seat 3, and the fins 62 synchronize the rotation of the disc 61, and when the fins 62 rotate, the impact structure is extruded and turned over, and when the rotation continues, the impact mechanism is separated from the fins 62, and the impact structure is reset, and when the impact structure is reset, a vibration is generated to be transmitted to the mounting seat 3, and the vibration is used to shake off the waste on the mounting seat 3, so that the residue of polishing waste on the mounting seat 3 is reduced. In the ascending process, the clamping mechanism 4 is loose, vibration is transmitted to the metal piece 7 due to the generation of vibration, and the metal piece 7 possibly slides down from the mounting seat 3, so the compensation piece 43 is arranged into a parallelogram, and therefore the compensation piece 43 ascends along with the mounting seat 3 and rotates in the initial stage of the ascending process, and when the compensation piece 43 rotates, one edge of the compensation piece 43 can be attached to the vertical plate 56, so that the metal piece 7 is still fixed by the clamping mechanism 4 in the initial stage of the ascending process, the stability of the metal piece 7 is ensured, and the metal piece 7 is prevented from sliding down from the mounting seat 3 due to the vibration generated by the vibration part 6.
Referring to fig. 7 and 9, the striking structure is provided as a reed 66, one end of the reed 66 is mounted on the sliding sleeve 22, and the other end of the reed 66 extends to the rotational path of the fin 62. In yet another embodiment of the present invention, the spring 66 comprises a contact section 661, a bent section 662 and a horizontal section 663 connected in sequence, the horizontal section 663 being connected to the sliding sleeve 22, and the contact section 661 extending between the fins 62, such that as the fins 62 rotate, the contact section 661 is pressed to turn over, and as the turning over continues, the fins 62 and the contact section 661 are disengaged, such that the contact section 661 impacts the next fin 62 to vibrate when reset. Vibration is transmitted to the installation seat 3, and waste materials on the installation seat 3 are vibrated to fall.
Referring to fig. 7 and 8, the striking structure further includes a striking plate 63, a fixing base 64, and a second spring 65, wherein the striking plate 63 is rotatably connected to the fixing base 64, a pair of second springs 65 are respectively disposed on two sides of the striking plate 63, and a lower end of the second springs 65 is mounted on the fixing base 64. In still another embodiment of the present invention, the fixing base 64 is fixedly installed on the sliding sleeve 22, the striking plate 63 is rotatably connected to the fixing base 64, and the striking plate 63 is respectively disposed at two sides of the striking plate 63 through the second spring 65, so that the striking plate 63 is kept in a vertical state, and one end of the striking plate 63 extends between the fins 62, when the fins 62 rotate, the striking plate 63 is extruded to turn over, and as the turning angle of the fins 62 increases, the fins 62 and the striking plate 63 are separated, so that under the action of the elastic force of the second spring 65, the striking plate 63 resets, and when the striking plate 63 resets, the next fin 62 is impacted, so that a vibration is generated, and the vibration is transmitted to the mounting seat 3, and the waste on the mounting seat 3 is vibrated by the vibration.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
