A fixing ring connection hole 406 is formed on the upper end surface and the lower end surface of the housing 205, respectively.
One end of the support bar 404 is provided with a first telescopic link connection hole 400, and the other end of the support bar 404 is provided with a second telescopic link connection hole. A third telescopic link connection hole 401 is formed in one end of the telescopic link 405 away from the support bar 404. The third telescopic link connection hole 401 and the first flexible cover connection hole 402 are connected by one set screw 207. The second telescopic link connection hole and the second flexible cover connection hole 403 are connected by a set screw 207. The first telescopic link connection hole 400 and the fixing ring connection hole 406 are connected by a fixing screw 207. When the first flexible cover connection holes 402 on both sides of the flexible cover 208 are extruded and retreated, the middle part of the flexible cover 208 cannot shrink back due to the existence of the support rods 404, so that the fitting degree of the front edge of the flexible cover 208 and the wall surface is ensured as much as possible, and the dust is prevented from overflowing.
The working process comprises the following steps: and starting the motor and the exhaust fan 411, wherein the motor drives the fifth gear to rotate through the fourth gear, finally drives the grinding rollers 200 to rotate, the two grinding rollers 200 rotate relatively, and then the grinding rollers 200 are tightly attached to the wall surface to be ground to start grinding. During polishing, a large amount of dust is generated, the dust is pumped and collected from the dust outlet pipe 410 under the action of the exhaust fan 411, meanwhile, the fan 408 is turned on, and the air hole 202 starts to blow, so that the dust falling in the flexible cover 208 and the dust scattered on two sides of the flexible cover 208 are concentrated towards the middle part of the flexible cover 208, the dust is conveniently sucked away, and dust accumulation on the lower edge of the air hole 202 is avoided.
When treating an arc-shaped interior corner (intrados): the first flexible cover connecting holes 402 on two sides of the flexible cover 208 are extruded and retreated, and the middle part of the flexible cover 208 cannot shrink back due to the existence of the supporting rods 404, so that the fitting degree of the front edge of the flexible cover 208 and the wall surface is ensured as much as possible, and the dust overflow is prevented.
When treating the exterior corner (extrados): firstly, the spring 505 is compressed, the two grinding rollers 200 are far away from each other, namely, the included angle between the two grinding roller supporting frames 201 is gradually increased, the wall surface is ground in the gradually increased process, then the grinding machine is slightly taken away, the spring 505 is gradually released from the compressed state, the included angle between the two grinding roller supporting frames 201 is gradually reduced, and thus, the efficient grinding of the external corner is realized.
During operation, a worker holds the pole 101 in one hand and holds the leveling grip 102 in the other hand. When the sanding lever 101 is changed from the vertical state to the inclined state, the leveling grip 102 is rotated so that the leveling grip 102 is kept horizontal all the time. The rotation of leveling handle 102 drives second gear 302 to rotate, and second gear 302 drives the second bevel gear to rotate, and the second bevel gear drives the montant to rotate, and the montant drives first bevel gear to rotate, and first bevel gear drives first gear 300 to rotate, and first gear 300 rotates and connects U-shaped frame 100 through the gear shaft drive, connects U-shaped frame 100 to rotate for shell connecting piece 409, connects U-shaped frame 100 to rotate for shell 205 promptly to realized when pole 101 takes place the slope, shell 205 can not take place the slope, thereby make grinding machanism wholly guarantee the level, prevent the dust from piling up in the corner of flexible cover 208.
In operation, the length of the entirety formed by the sanding lever 101 and the connection tube 104 may vary depending on the particular situation. The rocking handle 103 is rotated, the rocking handle 103 drives the third gear 305 to rotate through the second rotating shaft, the third gear 305 drives the third bevel gear 304 to rotate, and the third bevel gear 304 drives the screw 303 to rotate. Due to the threaded engagement of the screw 303 with the mounting groove, the screw 303 will move upward or downward relative to the sanding rod 101 as it rotates, thereby extending or shortening the length of the entirety formed by the sanding rod 101 and the connection tube 104.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
