[0028] Specifically, by pushing the connecting block 4, the mounting block 14 is inserted into the mounting groove 15. Through the sliding connection between the mounting block 14 and the mounting groove 15, the connecting block 4 is restricted on the connecting chamber 1. The fixing rod 26 and the fixing hole 25 are located on the same center line. By rotating the linkage rod 30, through the threaded connection between the linkage rod 30 and the first screw 32 and the sliding connection between the clamping plate 28 and the clamping groove 29, the first screw 32 drives the fixing rod 26 to move upward through the drive plate 27. The fixing rod 26 is inserted into the fixing hole 25, fixing the connecting block 4 on the connecting chamber 1.

[0029] Please see Figures 1 to 5 In this embodiment, the connecting block 4 is provided with an adjustment component for adjusting the height of the connecting chamber 1. The adjustment component includes a limiting rod 22, which is rotatably connected to the inside of the placement groove 17 via a bearing. A drive rod 19 is fixedly fitted on the outer peripheral wall of the limiting rod 22. A second screw 16 extending into the left side of the drive rod 19 is movably connected to the left side of the drive rod 19. A support plate 3 is fixedly connected to the left side of the second screw 16. Two rubber pads 18 are fixedly connected inside the placement groove 17.

[0031] Specifically, the drive rod 19 is conveniently fixed by the contact between the rubber pad 18 and the drive rod 19. When the height of the connecting chamber 1 needs to be adjusted, the drive rod 19 is pulled, and the drive rod 19 is disengaged from the placement slot 17. Through the action of the limiting rod 22, the drive rod 19 is rotated, so that the support plate 3 is in contact with the ground. The baffle 21 and the limiting rod 22 are in contact, which restricts the limiting rod 22. The connecting block 4 is grasped, and the support plate 3 is rotated. Through the threaded connection between the drive rod 19 and the second screw 16, the support plate 3 is moved, thereby adjusting the height of the connecting chamber 1.

[0032] The working principle of the above embodiments is as follows: Pushing the connecting block 4, the mounting block 14 is inserted into the mounting groove 15. Through the sliding connection between the mounting block 14 and the mounting groove 15, the connecting block 4 is fixed on the connecting chamber 1. The fixing rod 26 and the fixing hole 25 are on the same center line. Rotating the linkage rod 30, through the threaded connection between the linkage rod 30 and the first screw 32 and the sliding connection between the clamping plate 28 and the clamping groove 29, the first screw 32 drives the fixing rod 26 to move upward through the drive plate 27.

The drive rod 19 can be easily fixed through the contact between the rubber pad 18 and the drive rod 19. Starting the drive motor 24, the output shaft of the drive motor 24 drives the mounting rod 23 to rotate. The mounting rod 23 drives the gear 10 to rotate. Through the meshing between the gear 10 and the gear plate 9, the gear plate 9 is moved. The toothed plate 9, through the cooperation between the moving plate 11 and the connecting rod 12, drives the striking ball 13 to fit against the wall for hollow detection. The driving motor 24 rotates forward and backward, causing the striking ball 13 to reciprocate left and right. The sliding connection between the limiting block 5 and the limiting groove 20 supports the toothed plate 9, improving its stability. Similarly, the sliding connection between the positioning plate 7 and the positioning groove 8 supports the moving plate 11, improving its stability. When the height of the connecting chamber 1 needs adjustment, the driving rod 19 is pulled, disengaging from the placement groove 17. Through the action of the limiting rod 22, the driving rod 19 rotates, causing the support plate 3 to fit against the ground. The baffle 21 and the limiting rod 22 fit together, restricting the limiting rod 22. Grasping the connecting block 4, the support plate 3 is rotated. Through the threaded connection between the driving rod 19 and the second screw 16, the support plate 3 moves, thereby adjusting the height of the connecting chamber 1.
