[0043] A sliding frame 2 is slidably connected with the support frame 1, and a plurality of impact mechanisms 3 are horizontally slidably connected with the sliding frame 2. A positioning assembly 4 is connected between each of the impact mechanisms 3 and the sliding frame 2, and the positioning assembly 4 can fixedly connect the impact mechanism 3 with the sliding frame 2.

[0044] The sliding frame 2 is fixedly connected with a connecting plate 11, and a dust removal mechanism 5 is arranged between the connecting plate 11 and the sliding frame 2. When the sliding frame 2 moves relative to the connecting plate 11, the dust removal mechanism 5 can absorb dust in the air.

[0045] The sliding frame 2 is fixedly connected with a connecting seat 12, the connecting seat 12 is slidably connected with the connecting plate 11, and two connecting rods 13 are rotatably connected with the connecting seat 12. One end of each of the connecting rods 13 is rotatably connected with a sliding block 14, the sliding block 14 is slidably connected with the support frame 1, and an elastic assembly 6 is connected between the sliding block 14 and the support frame 1.

[0046] The support frame 1 is slidably connected with a limiting mechanism 7, the limiting mechanism 7 is telescopic, and the two ends of the limiting mechanism 7 are respectively inserted with one sliding block 14.

[0047] The limiting mechanism 7 is connected with a driving mechanism 8, the driving mechanism 8 drives the limiting mechanism 7 to slide and extend, so as to stretch the elastic assembly 6.

[0048] The impact mechanism 3 comprises an impact head 31, a fixed rod 32, a first spring 33, a sliding rod 34 and a connecting sleeve 35.

[0049] The fixed rod 32 is fixedly connected with the impact head 31, and one end of the fixed rod 32 is fixedly connected with the sliding rod 34. A sliding groove 9 is obliquely arranged in the connecting sleeve 35 relative to the vertical direction, the sliding rod 34 is inserted in the sliding groove 9, and the first spring 33 is sleeved outside the fixed rod 32.

[0050] The positioning component 4 includes a positioning plate 41, a threaded rod 42, and a moving block 43;

[0051] The sliding frame 2 is provided with a strip groove 15, the moving block 43 is slidably connected in the strip groove 15, one end of the connecting sleeve 35 is fixedly connected to the moving block 43, the positioning plate 41 is fixedly connected to the threaded rod 42, and the threaded rod 42 is threadedly connected to the moving block 43.

[0052] Working principle:

[0053] The support frame 1 is fixed to the wall by suction cup 10. The drive mechanism 8 is started. The drive mechanism 8 drives the limiting mechanism 7 to slide and extend, thereby causing the slider 14 to stretch the elastic component 6. At this time, the slider 14 pulls the connecting seat 12 through the connecting rod 13. The connecting seat 12 drives the sliding frame 2 to move upward. The impact mechanism 3 and the sliding frame 2 are both connected by a positioning component 4. The positioning component 4 can fix the impact mechanism 3 and the sliding frame 2, so that the sliding frame 2 drives the impact mechanism 3 to move synchronously.

[0054] Then, adjust the limiting mechanism 7 to release the fixation of the two sliders 14 by the limiting mechanism 7. Under the elastic force of the elastic component 6, the slider 14 pushes the connecting seat 12 through the connecting rod 13. The connecting seat 12 drives the impact mechanism 3 to impact the wall. The wall hardness is then judged based on the degree of wall indentation.

[0055] When the sliding frame 2 moves relative to the connecting plate 11, the dust removal mechanism 5 can absorb dust from the air.

[0056] In the impact mechanism 3, when the impact head 31 impacts the wall, the first spring 33 is compressed by force, and the fixed rod 32 slides relative to the connecting sleeve 35. At this time, under the guidance of the slide groove 9, the slide rod 34 slides along the slide groove 9. The slide rod 34 drives the impact head 31 to twist through the fixed rod 32. The impact head 31 rubs against the wall, thereby removing the wall paint adhering to the surface of the impact head 31 and ensuring the cleanliness of the impact head 31.

[0057] In the positioning assembly 4, the threaded rod 42 drives the positioning plate 41 to abut against the end face of the sliding frame 2, thereby connecting and fixing the moving block 43 to the sliding frame 2; rotating the threaded rod 42 causes the positioning plate 41 to move vertically, thereby releasing the fixing of the moving block 43 to the sliding frame 2, and then pushing the moving block 43 to slide in the strip groove 15, thereby adjusting the distance between the impact heads 31 and adjusting the measurement position.
