Further, the side of the bearing seat 210 is provided with a plurality of connecting cylinders 270, the connecting cylinders 270 are rotatably connected with rotating rods 271, rotating plates 272 are arranged above the rotating rods 271, adjusting holes 273 are formed in the tail ends of the rotating plates 272, threaded screws 275 are connected with the adjusting holes 273 in the adjusting holes 273, pressing plates 274 are arranged below the screws 275, the straight plates 101 are thoroughly positioned, the swinging of the straight plates is prevented, and meanwhile the smearing structure 100 can be taken out conveniently for overhauling and cleaning.

Still further, connecting axle 250 includes spread groove 252, the spread groove 252 top is equipped with spacing groove 253, dwang 260 one end is equipped with stopper 261, stopper 261's size and spacing groove 253 phase-match, joint complex dwang 260 and connecting axle 250 are convenient for take off at any time, facilitate the use, dwang 260 tail end is rotated and is connected with and changes cover 263, dwang 260 rear is equipped with limiting plate 262, conveniently rotates through changeing cover 263, set up limiting plate 262 simultaneously and prevent to change cover 263 and drop.

In addition, straight board 101 top is equipped with locating lever 280, and the articulated cooperation of locating lever 280 tail end is on bottom plate 201, and locating plate 281 the place ahead is equipped with locating plate 281, and locating plate 281 and scraper blade 110 parallel and level are equipped with balancing piece 282 below locating lever 280, have seted up the arc groove 283 on the balancing piece 282, cooperate locating plate 281 through locating lever 280 to fix a position the device, conveniently hold operating position and distance.

In addition, bottom plate 201 below is connected with a plurality of universal wheels 203, provides the removal function, conveniently removes whole device, is equipped with brake block 204 on the universal wheel 203, and bottom plate 201 rear is equipped with push rod 202, and push rod 202 is the backward bending, conveniently promotes.

When the repair paste machine is used, firstly, a power supply is switched on to enable the motor 140 to work, the motor 140 drives the rotary disc 141 to rotate, so as to drive the eccentric rod 142 to slide in the long groove 144 and be matched with the eccentric rod 142 which is eccentrically arranged, the moving plate 143 is opened to move left and right, meanwhile, the moving plate 143 drives the connecting plate 150 to reciprocate left and right through the fixing column 145, the repair paste on the wall surface is scraped back and forth through the scraper 110 which is arranged on the connecting plate 150, then, the smearing roller 120 which is arranged at the bottom of the connecting plate 150 is matched, the smearing roller 120 rotates on the wall surface while reciprocating left and right, so as to evenly smear the repair paste, then, the connecting shaft 250 is driven to rotate through the rotating rod 260, so as to drive the second gear 241 to rotate, meanwhile, the first gear 240 which is meshed with the second gear 241 starts to rotate, the coaxial screw rod, the screw rod 243 rotates to make the screw sleeve 220 start to rise, and drives the bearing seat 210 connected to the screw sleeve 220 to rise, so that the smearing structure 100 fixed on the bearing seat 210 can reach the high position of the wall to start working.
