The rotating tooth 312 is rotated by a first driving motor, and the rotating tooth 312 is meshed with the inner side of the bottom ring 1; Figure 5 As shown, the rotating rings 311 on the three clamping hands 3 overlap from top to bottom, the cross bars 31 of the three clamping hands 3 have the same height, the annular groove 21 is provided on the shaft seat 2, the three rotating rings 311 are rotatably arranged in the annular groove 21 at the same time, and the moving part 32 is reciprocatingly arranged on the cross bar 31, as shown in FIG. Figure 4As shown, the movable part 32 includes a shift seat 321, a through slot 3211 is provided on the shift seat 321, the cross bar 31 slides in the through slot 3211, a driving tooth 322 is provided in the shift seat 321, the driving tooth 322 is driven to rotate by a third driving motor, the driving tooth 322 is engaged with the side of the cross bar 31, a telescopic cylinder 33 is fixed on the top of the movable part 32, a bent rod 34 is provided at the telescopic end of the telescopic cylinder 33, the bent rod 34 is bent upward and fixed with another telescopic cylinder 33, the output shafts of the two telescopic cylinders 33 are coaxially arranged and the telescopic directions are opposite, and the end of the telescopic cylinder 33 is fixed with a supporting ball head 331.

[0022] This inspection tool is used to clamp a large-area thin car roof, which is convenient for observation at various angles. When clamping the car roof, the bottom edge of the car roof is supported by adjusting the rotation angle of the three clamping hands 3 and the telescopic length of the telescopic cylinder 33 located at the lower position of the clamping hands 3, and the car roof is clamped by the telescopic cylinder 33 located at the upper position of the clamping hands 3; through three-point positioning, the car roof can be stably supported. After clamping, the three lower telescopic cylinders 33 can also be lifted and lowered respectively, and the car roof can be flipped to a certain extent by cooperating with the movement of the shift seat 321 on the cross bar 31. The support of the car roof by the support ball head 331 can always clamp and fit the surface of the car roof when the car roof is flipped; the rotation angle of the three clamping hands 3 and the displacement of the rotating seat can follow the shape of the car roof and find a suitable support point when initially clamping the car roof. The three-point clamping of this device is stable, the space is open, it is convenient for multi-angle observation, and it can be flipped at any time, which is conducive to the maintenance and inspection of the car roof.

[0023] In a further solution, Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, it also includes a workbench 4, the bottom ring 1 is fixed on the workbench 4, the shaft seat 2 is rotatably set on the workbench 4, the shaft seat 2 is rotated by the second driving motor, a hydraulic cylinder 22 is fixed on the top of the shaft seat 2, the output end of the hydraulic cylinder 22 is coaxially arranged with the shaft seat 2, a cavity 23 is arranged inside the shaft seat 2, a stop block 24 is arranged in the cavity 23 along the radial sliding of the shaft seat 2, the stop block 24 has three and is arranged around the output shaft of the hydraulic cylinder 22, the stop block 24 is provided with an inclined groove 241 extending downward and inclined toward the axial direction of the shaft seat 2, a horizontal axis 25 is slidably provided on the inclined groove 241, the horizontal axis 25 is fixed to the output end of the hydraulic cylinder 22, the hydraulic cylinder 22 moves the horizontal axis 25 downward, so that the stop block 24 moves outward, and the stop block 24 passes through the cavity 23 and abuts against the inner side of the swivel 311.

[0024] In this scheme, after clamping the car roof, the hydraulic cylinder 22 is pressed downward to move the horizontal axis 25 along the inclined groove 241 of the stop block 24, pushing the stop block 24 to move outward and against the inner side of the three swivel rings 311. Through the pressure of multiple stop blocks 24, the friction between the stop blocks 24 and the inner sides of the three swivel rings 311 connects the swivel rings 311 and the axis seat 2. At this time, the motor directly drives the axis seat 2 to rotate, and the outer end of the cross bar 31 moves along the inner side of the bottom ring 1, and the three clamping hands 3 drive the car roof to rotate in a circle. This structure can fix the rotation angle of the clamping hands 3 after the car roof is clamped, and rotate the entire car roof, cooperate with the flipping of the car roof, and further assist in the observation and detection of various angles of the car roof.

[0025] In a further solution, Figure 2 and Figure 4 The curved rod 34 includes a straight rod 341 and an L-shaped rod 342. One end of the straight rod 341 is rotatably set at the output end of the telescopic cylinder 33 at the lower position, and the other end is hinged to the L-shaped rod 342. A limiting portion 343 for making the L-shaped rod 342 perpendicular to the straight rod 341 and a locking screw 344 for locking the L-shaped rod 342 and the straight rod 341 are provided at the hinge of the straight rod 341 and the L-shaped rod 342.

[0026] In this structure, the curved rod 34 can fix the upper telescopic cylinder 33 above the lower telescopic cylinder 33 through the locking screw 344 and the limit part 343. By loosening the locking screw 344, the L-shaped rod 342 can be rotated to make the upper telescopic cylinder 33 move away from the lower telescopic cylinder 33. This structure can facilitate the direct placement and removal of the car roof.

[0027] In a further solution, Figure 2 and Figure 5 The upper side of the swivel 311 and the bottom side of the annular groove 21 are provided with a protruding convex ring, and the lower side of the swivel 311 and the top side of the annular groove 21 are provided with a concave ring that cooperates with the convex ring. By arranging the convex ring and the concave ring that cooperate in sequence, the three swivels 311 and the annular groove 21 can be easily coaxially matched, so that the cross bar 31 will not shake when rotating, and when the stop block 24 is squeezed and converted, a compression force is formed with the stop block 24, which facilitates the generation of friction between the swivel 311 and the stop block 24.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
