A fixed seat is fixedly connected to the left side wall body of the inner cavity of the driving receiving groove. A fixed groove is opened on the right side wall body of the fixed seat. An installation block is inserted into the inner cavity of the fixed groove. A horizontal hydraulic push rod is horizontally arranged on the right middle wall body of the installation block. The right end of the horizontal hydraulic push rod is detachably connected to a compression plate. A support frame is arranged at the left end of the bottom of the horizontal hydraulic push rod.

In addition, a hook post (or hook) matching the box pulling mechanism 36 is arranged at the bottom of the rear end of the storage box 4.

[0046] Specifically, the hydraulic claw assembly 35 of this embodiment includes a first hydraulic cylinder 351 with one end connected to the compression outer box 31, a first fixed seat 352 fixed on the compression outer box 31, a second crank arm 356 with one end pivotally connected to the other end of the first hydraulic cylinder 351 and the other end pivotally connected to the first fixed seat 352, a first crank arm 353 with one end pivotally connected to the joint of the second crank arm 356 and the first hydraulic cylinder 351 and being arc-shaped, a front claw 354 pivotally connected to the middle of the first fixed seat 352, the other end of the rear end pivotally connected to the first crank arm 353 and driven by the first hydraulic cylinder 351, and a hydraulic cylinder outer cover 355 fixed on the compression outer box 31 and covering the first hydraulic cylinder 351.
