Figure 1 、 Figure 2 and Figure 3, including a back plate 1, one end surface of the back plate 1 is connected to two wedge bodies 2, a universal wheel 3 is provided at the lower middle part of the wedge body 2, and an auxiliary component 4 is provided at the connection between the universal wheel 3 and the inner cavity of the middle part of the wedge body 2. The two wedge bodies 2 are both designed in the shape of an isosceles triangle, and the ends of the two wedge bodies 2 close to each other are in a connected state. There are four groups of universal wheels 3 and auxiliary components 4. The four groups of universal wheels 3 and auxiliary components 4 are distributed in a rectangular shape on the two wedge bodies 2, and the wheel body of each group of universal wheels 3 is provided with a brake pad. The brake pad on the universal wheel 3 facilitates the locking effect of its own rolling state;

[0031] The auxiliary component 4 includes a recessed hole 41 embedded in the middle of the top of the wedge body 2. A connecting hole 42 is formed in the center of the bottom of the recessed hole 41. A movable hole 43 is formed in the center of the bottom of the connecting hole 42. The movable hole 43, the connecting hole 42, and the recessed hole 41 all vertically penetrate the inner cavity of the wedge body 2. A connecting rod 44 is rotatably sleeved through the inner wall of the movable hole 43. A rotating column 45 is fixedly connected to the top of the connecting rod 44, and a connecting piece 46 is fixedly connected to the bottom of the connecting rod 44. A threaded rod 47 is fixedly connected to the bottom of the connecting piece 46. A threaded barrel 48 is threadedly connected to the outer wall of the threaded rod 47. The threaded barrel 48 and the connecting piece 46 are both rotatably sleeved on the inner wall of the movable hole 43, and the bottom of the threaded barrel 48 is fixedly connected to the universal wheel 3.

[0032] The rotating column 45 is rotatably sleeved on the inner wall of the recessed hole 41, and a screwing groove 4501 is provided at the center position of the top of the rotating column 45, and the screwing groove 4501 is a regular hexagonal columnar groove structure.

[0033] The working principle of this embodiment is as follows: when in use, the blocking wedge to be modified is removed, each universal wheel 3 at the bottom of the blocking wedge is placed on the ground, and then pushed into the position to be blocked. After the wedge is in place, the brake pads on each universal wheel 3 are moved to fix it;

[0034] When the vertical height of the universal wheel 3 needs to be adjusted, it is only necessary to use a hexagonal tool to insert the screw groove 4501 and screw it to rotate the rotating column 45, and then drive the connecting rod 44, the connecting piece 46 and the threaded rod 47 to rotate synchronously. At the same time, the corresponding universal wheel 3 can be indirectly pushed to perform position adjustment operation by utilizing the threaded connection between the threaded rod 47 and the threaded cylinder 48, and the sliding limit state of the limit slider 4801 and the limit slot 4802 on the threaded cylinder 48.
