[0013] Furthermore, two limiting members are fixedly connected to the outer surface of the installation frame. Two limiting rods are slidably connected to the inside of each limiting member.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. By arranging components such as rolling plates and rolling rollers, through the mutual cooperation relationship between the rolling plates and the rolling rollers, the adjusting rod can drive the rolling rollers to move through the support members and the rolling plates, so that the rolling rollers extrude the inner wall of the trench, and thus the device can compact the inner wall of the trench by arranging the rolling plates and the rolling rollers, solving the problem that the current technical solution lacks a rolling mechanism, is not convenient for compacting the inner wall of the trench, and is not convenient for solving the problem of soil collapse on the inner wall of the trench.
