the eccentric shaft is arranged on the connecting block, the connecting block is provided with a swinging block, the swinging block comprises a connecting part and a swinging part, the connecting part is sleeved on the connecting block of the eccentric shaft, and the swinging part is connected with the side surface of the connecting part through an integrated structure;
the transmission shaft is provided with a switching sleeve and a polishing disc;
the top of the polishing disc is provided with an installation groove, the adapter sleeve is arranged in the installation groove, and a first deep groove ball bearing is arranged between the adapter sleeve and a transmission shaft of the eccentric shaft; the bottom of polishing dish is equipped with the spread groove, is equipped with second deep groove ball bearing in the spread groove, and the second deep groove ball bearing is passed to the bottom of transmission shaft, and connects fixedly through the nut.
Furthermore, the surface of the polishing disk is provided with a plurality of structural reinforcing ribs.
Furthermore, a heat radiation fan is arranged at the top of the motor.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the eccentric power that produces when the eccentric shaft rotates drives the polishing dish and rotates again, and the rotation mode at this moment has become eccentric rotation by coaxial rotation to there is certain amplitude, and the amplitude that the piece produced will be thrown in the amplitude of production and offset each other, makes the rotational speed reduce, and makes the quotation rotation range grow of polishing dish.
2. Seen from the direction of the surface of the polishing disk, the polishing disk is not a single circle, but is in a similar circle shape formed by dispersing a plurality of circles around the center in a certain range, and the action during manual polishing is simulated.

Fig. 1 is a schematic view of the floor polishing machine with an eccentric shaft transmission structure according to the present invention.
Fig. 2 is a cross-sectional view of the floor polishing machine with the eccentric shaft transmission structure of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1 and 2, the floor polishing machine with an eccentric shaft transmission structure according to the present invention includes a motor 2, wherein the motor 2 is disposed on a motor mounting plate 3;
an output shaft 21 of the motor 2 penetrates through the motor mounting plate 3 and is in transmission connection with the eccentric shaft 7; the eccentric shaft 7 comprises a connecting block 71 and a transmission shaft 72, a threaded hole for connecting with the output shaft 21 is formed in the top of the connecting block 71, and the transmission shaft 72 is eccentrically arranged at the bottom of the connecting block 71;
the connecting block 71 is provided with a swinging block 4, the swinging block 4 comprises a connecting part 41 and a swinging part 42, the connecting part 41 is sleeved on the connecting block 71 of the eccentric shaft 7, and the swinging part 42 is connected with the side surface of the connecting part 41 through an integrated structure;
the transmission shaft 72 is provided with a switching sleeve 5 and a polishing disk 10;
the top of the polishing disc 10 is provided with a mounting groove, the adapter sleeve 5 is arranged in the mounting groove, and a first deep groove ball bearing 6 is arranged between the adapter sleeve 5 and a transmission shaft 72 of the eccentric shaft 7; the bottom of polishing dish 10 is equipped with the spread groove, is equipped with second deep groove ball bearing 8 in the spread groove, and second deep groove ball bearing 8 is passed to the bottom of transmission shaft 72, and connects fixedly through nut 9.
