[0023] In this embodiment, an arc-shaped clamping plate 17 is fixedly connected to one of the adjacent ends of the two sets of second electric telescopic rods 16. The arc-shaped clamping plate 17 is C-shaped, and a valve is movably connected to one of the adjacent sides of the two sets of arc-shaped clamping plates 17.
[0024] Specifically, when the second electric telescopic rod 16 moves, it drives the arc-shaped clamping plate 17 to move, and the two sets of arc-shaped clamping plates 17 together clamp the valve.
[0025] In this embodiment, two sets of symmetrical first electric telescopic rods 5 are fixedly connected to the front and rear ends of the first mounting plate 4, and a second mounting plate 6 is fixedly connected to the ends of the two sets of first electric telescopic rods 5 that are far apart from each other.
[0026] Specifically, the first mounting plate 4 restricts the position of the first electric telescopic rod 5, and the output shaft of the first electric telescopic rod 5 drives the second mounting plate 6 to move.
[0027] In this embodiment, a motor 7 is mounted on the front end of the second mounting plate 6. The output shaft of the motor 7 passes through the second mounting plate 6. A gear 8 is fixedly connected to the output shaft of the motor 7. An external gear ring 11 is rotatably connected to the outer side of the gear 8.
[0028] Specifically, the second mounting plate 6 restricts the position of the motor 7, and the output shaft of the motor 7 drives the gear 8 to rotate, which in turn drives the external gear ring 11 to rotate.
[0029] In this embodiment, two sets of locking blocks 9 are rotatably connected to the front and rear ends of the outer gear 8 of the output shaft of the motor 7. Rollers 10 are rotatably connected to the close ends of the two sets of locking blocks 9. Slide grooves are provided at both the front and rear ends of the outer gear ring 11, and the rollers 10 are slidably connected to the inner side of the slide grooves.
[0030] Specifically, the output shaft of motor 7 drives gear 8 to rotate, and the clamping block 9 uses roller 10 to clamp the outer gear ring 11. Gear 8 drives the outer gear ring 11 to rotate, and roller 10 rotates in the groove of the outer gear ring 11 to assist the rotation of the outer gear ring 11 and reduce friction.
[0031] In this embodiment, two sets of symmetrical first connecting rods 12 are fixedly connected to the inner wall of the outer toothed ring 11, and a second connecting rod 14 is slidably connected to the inner side of the first connecting rod 12. A cleaning block 15 is fixedly connected to the other end of the second connecting rod 14.
[0032] Specifically, the external toothed ring 11 drives the first connecting rod 12 to rotate, and the first connecting rod 12 drives the cleaning block 15 to rotate through the second connecting rod 14.

[0034] Specifically, when the second connecting rod 14 is subjected to force, the spring 13 is compressed. The spring 13 is located inside the first connecting rod 12. When the spring 13 is compressed, the second connecting rod 14 slides inside the first connecting rod 12.
[0035] Working Principle: When using this equipment, the valve to be inspected is placed in the middle of the base 1. The second electric telescopic rod 16, installed in the bracket 3, is activated. The output shaft of the second electric telescopic rod 16 drives the arc-shaped clamping plate 17 to move. The two sets of arc-shaped clamping plates 17 clamp the valve, allowing the pipeline of the oil tank 2 to pass through the external toothed ring 11 and connect with the valve's inlet and outlet. The oil tank 2 is activated to supply lubricating oil into the valve. After passing through the valve, the lubricating oil flows to another set of oil tanks 2. If the valve's inlet and outlet seals are not up to standard, oil leakage will occur. The first electric telescopic rod 5, installed on the first mounting plate 4, is then activated. The output shaft of motor 5 drives the second mounting plate 6 to move, starting motor 7. The output shaft of motor 7 drives gear 8 to rotate. The clamping block 9 uses roller 10 to clamp the outer gear ring 11. Gear 8 drives the outer gear ring 11 to rotate. Roller 10 rotates in the groove of outer gear ring 11 to assist the rotation of outer gear ring 11 and reduce friction. Outer gear ring 11 drives the first connecting rod 12 to rotate. The first connecting rod 12 drives the cleaning block 15 to rotate through the second connecting rod 14. The cleaning block 15 uses the elastic force of spring 13 to keep it tightly clamped to the pipe and cleans the oil leak under the rotation of outer gear ring 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
