Thus, the present application is not limited to the specific embodiments described below, but only by the claims and their equivalents.

Fig. 1 to 10 show a specific embodiment of the balance block structure of the round sander of the present application.

A balance block structure of a round sanding machine 100 for use in rotation of a sanding disc 2 of the round sanding machine 100, wherein the balance block structure comprises: namely a first balance weight 10a and a second balance weight 10b, wherein the two balance weights are integrated; a rotating hole 10c penetrates through the upper part of the first weight 10 a; a filling opening 10d is hollowed in the first balance weight 10 a; the second balancing weight 10b is outwards protruded along the side wall of the first balancing weight 10a to form a step shape, two blocky balancing weights are utilized, the upper portion is provided with a connecting hole, installation is facilitated, a filling port is formed along the inside, then a balancing position is sleeved, integration of the balancing structure is guaranteed, processing is facilitated, the balancing structure is integrally sleeved stably, and the change is not easy to occur.

In combination with the corresponding structure, the circular sander 100 has a circular sander 100 that drives a corresponding sanding disk 2 to perform sanding rotation by means of a rotor 14 inside the circular sander 100. The connection is made by the drive shaft 10c1, but it is needless to say that the shaft of the rotor may be rotated instead of the drive shaft 10c 1.

In which, in combination with corresponding structures, as shown in fig. 1, 7 and 10, in the present embodiment,

a balance weight structure of a round sand machine 100 is used for rotation of a sand plate 2 of the round sand machine 100, wherein the balance weight structure comprises a first balance weight 10a and a second balance weight 10 b.

Two cuboid-shaped balancing blocks assist the corresponding structures to rotate, wherein, in combination with the corresponding figure 6, the balancing block 10 is arranged in a groove in the middle of the fan blade 11 to rotate.
