The working principle is as follows: when the device is used, the device is pushed to the wood board wall surface, so that cleaning bristles on the cleaning mechanism 31 are in contact with the wall surface, the exhaust fan 16 is started to work, the exhaust fan 16 continuously sucks outside air into the arc-shaped shell 24 through the first air pipe 17, the second air pipe 26 and the U-shaped pipe 25, then sucks the air into the circular shell 9 and finally extracts the air, when the outside air enters the arc-shaped shell 24, the fan blades 3102 are driven to rotate so as to drive the outer rod 3101 to rotate, the outer rod 3101 drives the mounting block 3103 and the inner rod 3105 to rotate so as to drive the mounting rod 3107 to rotate so as to drive the sleeve rod 3108 to rotate so as to drive the cleaning bristles to rotate, when the sleeve rod 3108 rotates, the centrifugal force can move outwards to compress the second spring 3110 so as to generate acting force, at the moment, the sleeve rod 3108 moves outwards to expand, the wall surface is cleaned through the cleaning bristles, so that the dust on the wall surface to be adsorbed by the accessories 28, the situation that the adsorption part 28 is not tightly adsorbed due to the existence of dust is avoided, the cleaned dust and impurities are sucked into the arc-shaped shell 24 and are blocked by the filter screen and are left in the arc-shaped shell 24, the cleaned dust is collected, after the cleaning is finished, the power of the exhaust fan 16 is reduced, so that the centrifugal force generated by the loop bar 3108 is reduced, at the moment, the second spring 3110 releases acting force to drive the loop bar 3108 to reset, the device is pushed to the wall surface, at the moment, the backing plate 3106 is in contact with the wall surface, the inner bar 3105 and the loop bar 3108 are continuously retracted into the adsorption part 31028 along with the pushing of the device, when the inner bar 3105 moves, the mounting block 3103 is driven to move along with the device to compress the first spring 3104, so that the acting force is generated by the deformation of the first spring 3104, at the same time, the adsorption part 28 is close to the wall surface and is finally attached to the wall surface, at the moment, the, the situation that the wall surface is extruded by the fact that the first spring 3104 releases acting force to drive the mounting block 3103 to move rightwards so as to drive the inner rod 3105 and the base plate 3106 to move outwards is avoided, at the moment, the exhaust fan 16 continues to work to suck air in the adsorption piece 28 away to enable the interior of the adsorption piece to be in a negative pressure state so as to enable the adsorption piece 28 and the wall surface to be adsorbed and fixed, at the moment, the exhaust fan 16 can be closed, due to the arrangement of the one-way air valve 27, the air in the U-shaped pipe 25 can only be drawn outwards and can not flow back inwards, so that the arc-shaped shell 24 and the adsorption piece 18 are guaranteed to be in a negative pressure state, at the moment, the four adsorption pieces 18 adsorb the wall surface from the periphery of the contacted wall surface from the rebound tester 15, the electric telescopic rod 13 is started to extend to drive the connecting plate 14, the rebound tester 15 to move right, The rack plate 21 moves along with the rack plate to drive the gear 23 to rotate so as to drive the rotating shaft to rotate and further drive the arc-shaped shells 24 to rotate so as to drive the four adsorption pieces 28 to move along with the rack plate to pull the wood board wall outwards, the wood board wall is extruded along with the continuous movement of the rebound tester 15 so as to measure hardness data, the rebound tester 15 is in contact with the wood board wall to cause pressure to the wood board wall so as to cause the wood board wall to be sunken, the wood board wall is prevented from being sunken due to the acting force of the rebound tester 15 by the outward pulling of the four adsorption pieces 28, the condition that the thickness of the wood board is reduced to influence detection data occurs, the round cover 29 can be opened after the detection is finished, and the adsorption of the wood board is cancelled due to the negative pressure state in the arc-shaped shells 24 and the adsorption pieces 28, the fixing rod 18 is rotated to be separated from the clamping hole, the barrel body 11 can be rotated to drive the arc-shaped shells 24 to rotate at the moment, so that the dust in the barrel body is poured out to clean the dust, the motor 6 can be started to drive the output shaft of the motor to rotate to drive the worm 5 to rotate so as to drive the two worm wheels 4 to rotate to realize the rotation of the pair of screw rods 3, and the support plate 7 and the support plate 8 are driven to ascend to realize the height change of the rebound tester 15, so that the position of a detection position can be adjusted.
