[0026] Specifically, such as Figure 4 As shown, the lifting mechanism 4 includes a bracket 402 installed on the main oil tank 401, a telescopic rod 403 is installed on the bracket 402, the telescopic rod 403 is fixedly connected to the crank 405, an elastic member 404 is installed between the crank 405 and the bracket 402, and the crank 405 and the bracket 402 are slidably connected; a slide groove 407 is provided on the bracket 402, the crank 405 is slidably connected to the slide groove 407, and the crank 405 and the bracket 402 are slidably connected via the slide groove 407.
[0027] In this embodiment: because the lifting mechanism 4 includes a main oil tank 401 fixedly connected to the device body 1, the main oil tank 401 is fixedly connected to the bracket 402, the telescopic rod 403 is slidably connected to the bracket 402, and an elastic member 404 is installed between the bracket 402 and the crank 405. The elastic force of the elastic member 404 can drive the crank 405 to move up and down, thereby squeezing the chain 2, making the chain 2 tighter, so that the chain 2 runs more smoothly, and the position of the oil distribution tank 501 can also be adjusted according to the specifications of the chain 2.
[0028] The smearing mechanism 5 is mounted on the crank 405 and is used to apply lubricating oil to the chain 2; the smearing mechanism 5 includes an oil distribution box 501 mounted on the crank 405, a connecting hose 406 is fixedly connected to the oil distribution box 501, and a roller 506 is installed on the oil distribution box 501.

The elastic force of the elastic member 404 can drive the crank 405 to move up and down, thereby squeezing the chain 2, making the chain 2 tighter, so that the chain 2 runs more smoothly. Because the smearing mechanism 5 includes The oil distribution tank 501 is fixedly connected to the crank 405, and a storage sponge 507 is installed inside the oil distribution tank 501, which can effectively prevent the lubricating oil from flowing too fast, making the lubricating oil more durable. Because the swing arm 505 is in contact with the chain 2 through the rubber head 508, the swing arm 505 can drive the roller 506 to rotate, so that the lubricating oil can be brought from the inside of the oil distribution tank 501 to the smear sponge 504, so that the smear sponge 504 can lubricate the chain 2, which can effectively reduce the wear of the chain 2.
[0032] The specific solution is: the staff can control the lifting mechanism 4 to drive the oil distribution box 501 to move upward, so that the device can adjust the position of the oil distribution box 501 according to the specifications of the chain 2, so that the chain 2 can be better coated with lubricating oil, and by controlling the coating mechanism 5, the chain 2 can be automatically coated with lubricating oil during the operation of the chain 2, thereby reducing the wear of the chain 2 during the force measurement process and ensuring the quality of the chain 2.
