[0039] With this design, the pallet 402 moves downward, driving the second roller 603 to move downward, thereby causing the second clamping block 602 to swing, which in turn causes the second silicone pad 605 at the other end of the second clamping block 602 to move closer to the oil inlet bend 10, thus sealing the corresponding second oil outlet 1004.
[0040] The second clamping block 602 is internally threaded with a first adjusting screw 606, which is correspondingly set with the second plug 604.
[0041] With this design, when the second silicone pad 605 wears out, the position of the second plug 604 can be adjusted by the first adjusting screw 606, so that the second silicone pad 605 is closer to the oil inlet bend 10, which can make up for the problem of poor sealing effect caused by the wear of the second silicone pad 605.

[0045] With this design, the pallet 402 moves downward, driving the third roller 703 to move downward, thereby causing the third clamping block 702 to swing. This causes the top block 704 at the other end of the third clamping block 702 to press the third plug 408 toward the oil inlet bend 10, and the third silicone pad 409 seals the corresponding second oil outlet 1004.
[0046] The third clamping block 702 is internally threaded with a second adjusting screw 705, which is arranged in correspondence with the top block 704.

[0050] In this way, the starting of the gas cylinder 801 can drive the pressing block 803 to press the two oil inlet elbows 10 to move downward, and the downward movement of the oil inlet elbows 10 forces the silica gel plate 404 and the supporting plate 402 to move downward. In this process, due to the elastic force of the first spring 403, the silica gel plate 404 is always in close contact with the bottom surface of the oil inlet elbow 10, thereby effectively sealing the first oil outlet 1002; the downward movement of the supporting plate 402 drives the first sealing device 5, the second sealing device 6 and the clamping device 7 to act simultaneously, thereby effectively sealing the oil inlet 1003 and the second oil outlet 1004.
[0051] The bottom plate 1 is provided with six lifting assemblies 9, which are respectively located below the corresponding first clamping block 502, second clamping block 602 and third clamping block 702.
[0052] The lifting assembly 9 comprises a fixed sleeve 901 fixedly connected with the bottom plate 1, and a top pin 902 slidingly connected in the fixed sleeve 901, a fourth spring 903 being sleeved on the top pin 902, and both ends of the fourth spring 903 being fixedly connected with the bottom plate 1 and the top pin 902 respectively.
[0053] The side surface of the supporting plate 402 is provided with an air inlet hole 4021, and the top surface of the supporting plate 402 is provided with two air outlet holes 4022, which are respectively arranged in correspondence with the two first oil outlets 1002, and the two air outlet holes 4022 are communicated with the air inlet hole 4021 through the channel formed in the supporting plate 402.
[0054] In this way, when the oil inlet elbow 10 is in close contact with the silica gel plate 404, the gas outlet hole 4022 is in communication with the corresponding first oil outlet 1002, the gas enters from the gas inlet hole 4021, and then enters the inside of the oil inlet elbow 10 from the gas outlet hole 4022 after passing through the channel inside the supporting plate 402, thereby providing sufficient gas for the sealing test of the oil inlet elbow 10.
[0055] In use, the oil inlet elbow 10 is first fixed and sealed by the tool, then the gas is filled into the inside of the oil inlet elbow 10 from the gas inlet hole 4021, and then the oil inlet elbow 10 and the tool are placed in water, and the detection test of the oil inlet elbow 10 can be quickly and reliably performed by whether there is bubble overflow.
