The operation and effect of the hand finishing machine according to the present invention will be described below.

First, in order to operate the hand finishing machine 10 of the present invention, the driving apparatus 100 is driven. When the driving device 100 is operated by using any one of hydraulic pressure, pneumatic pressure, and electric energy, the shaft 100 formed at the center of the lower end of the driving device 100 is rotated. Therefore, The compaction means 200 is rotationally driven to smooth the construction surface.

That is, the driving shaft 210 installed at the center of the bottom compaction unit 200 rotates in a shaft 110 formed at the center of the lower end of the driving unit 100, and the rotation of the driving shaft 210 The plurality of rotary blades 232 having the compaction plate 233 mounted on each of the side slopes of the rotary plate 231 are rotated to uniformly grind the floor.

As described above, in the process of evenly grinding the floor by the floor compaction unit 200, the operator can arbitrarily adjust the angle of the rotary blade 232 on which the compaction plate 233 is mounted according to the material of the floor construction or other working conditions .

That is, when the material of the floor construction is hardened due to the hardening of the floor construction in the process of making the bottom floor uniform by the floor compaction unit 200, the angle of the rotary vane 232 on which the compaction plate 233 is mounted is raised and used, When the material of the construction is moist and thin, the angle of the rotary blade 232 on which the compaction plate 233 is mounted is lowered and used horizontally.

When the angle adjuster 250 is rotated in the forward direction to change the angle of the floor compaction unit 200 according to the material of the floor construction, the rotation of the rotation plate 240 is upward, One side of the wing 232 rises to form an angle. On the other hand, when the wing 232 is turned in the opposite direction, the rotation of the rotation plate 232 is lowered and the rotation of the rotation wing 232 connected to the rotation plate 240 is lowered.

The rotary wing 232 is coupled to the rotary plate 231 of the compaction unit 230 by a hinge 234 and the rotary ring 241a mounted on the rotary transfer plate 240 is rotated by the rotary wing The rotation plate 240 is lifted upward and the pair of protrusions 241a and 242b connected to the rotation ring 241a are coupled to the pair of protrusions 235, The rotation of the swing arm 235 causes the swing arm 235 to rotate about the hinge 234 to form an angle. Conversely, when the swing arm 250 is rotated in the opposite direction, The connected pair protrusion 235 side rotates about the hinge 234 and descends to be horizontal.

The present invention is further characterized in that in the process of evenly grinding the floor by the floor compaction means 200, the worker flows the waterproofing liquid, the cement liquid, water or the like into the inflow hole 212 formed in the drive shaft 210, So that the floor can be floated with the floor compaction means 200. [

A hose (not shown in the figure) is attached to a discharge hole (not shown in the figure) formed at one side of the rotary plate 231 and an inflow hole (not shown in the figure) formed at one side of the rotary blade 232 And the waterproofing liquid and the cement liquid or water flowing into the inflow hole 212 of the drive shaft 210 are discharged from the rotary vane 232 through the hose and can be floored.
