[0026] When the two first hydraulic cylinders 402 work simultaneously, the two L-shaped plates 403 can drive the connecting plate 405 to move together, so that the two clamping arms 406 can move in the same direction or opposite directions. When the clamping arms 406 move in the same direction, the clamping plates 408 can clamp and fix the goods, and the supporting forks 412 can support the bottom of the goods, thereby improving the stability of the goods after being clamped and lifted. When smaller goods need to be clamped and fixed, the two second hydraulic cylinders 407 can be started to make the two second hydraulic cylinders 407 contract simultaneously, so that the two clamping plates 408 move towards each other, which reduces the distance between the two clamping plates 408, thereby realizing the clamping and fixing of smaller goods, making the device more convenient to use, and having a larger application range. When the clamping plates 408 move, the guide rods 411 also slide on the surface of the clamping arms 406, so that the clamping plates 408 can obtain additional guiding and supporting effect, thereby improving the stability of the clamping plates 408.

[0027] Further, the base 401 is fixed with two linear sliding rails 409 on the front surface, and the linear sliding rails 409 are slidingly connected with sliding blocks 410 on the surface.

[0035] Further, the surface of the U-shaped plate 301 is fixedly connected with a liquid storage tank 304, the top and the bottom of the liquid storage tank 304 are communicated with valves;

[0036] The water injection through the valve into the liquid storage tank 304 can increase the overall weight of the U-shaped plate 301, so as to reduce the center of gravity effect, so that after the base 401 moves forward, the device is not easy to tilt.

[0037] Further, the surface of the U-shaped plate 301 is fixedly connected with two telescopic rods 303 on the left and right sides, one end of the telescopic rod 303 is fixedly connected with the back surface of the base 401;

[0038] The weight of the base 401 can be transmitted to the surface of the plurality of telescopic rods 303, the telescopic rod 303 can improve the support effect of the base 401, and the telescopic rod 303 can also be telescopic, so that the base 401 can also be guided when moving forward and backward, and the stability of the base 401 when moving is improved.
