In this embodiment, a rotation gap is formed between the inner rotating sleeve 9 and the body 1, the inner rotating sleeve and the body 1 can rotate, and the outer diameter of the inner rotating sleeve 9 is slightly smaller than the inner diameter of the body 1, so that the inner rotating sleeve can rotate smoothly. The driving impeller 8 is fixedly connected with the rotating inner sleeve 9, and the outer diameter of the driving impeller 8 is the same as the inner diameter of the rotating inner sleeve 9 so as to ensure the installation tightness. And when the driving impeller 8 rotates in a single direction (for example, in a left-handed or right-handed direction, the rotating direction is determined by the direction of the drilling fluid) under the action of the drilling fluid, so that the rotating inner sleeve 9 can be driven to rotate. In the rotating process, the rotating inner sleeve 9 is connected with the toe cap 11, so that the toe cap 11 can be driven to rotate synchronously.
As shown in fig. 2, the driving impeller 8 includes an annular outer ring, an annular inner ring, and a plurality of driving blades, the annular outer ring is coaxially sleeved outside the annular inner ring, and the plurality of driving blades are uniformly distributed at an annular space between the annular outer ring and the annular inner ring.

When the embodiment is applied, the working process is as follows:
if the drilling fluid is blocked during the process of well cementation and casing running, when a pump is started to circulate the drilling fluid, the plug 3 moves downwards, the compression spring 4 enables the plug 3 to be separated from the axial through hole, the drilling fluid flows through the driving impeller 8 through the axial through hole and drives the driving impeller 8 to rotate, the driving impeller 8 drives the rotating inner sleeve 9 to rotate, and then the rotating inner sleeve 9 drives the shoe head 11 to rotate. While rotating, the drilling fluid can be ejected from the jet holes 12 on the toe cap 11 to form a rotational flow with high-speed impact, and the rotational flow can play a role in trimming and scouring irregular well walls, so that the sleeve can be smoothly put in.
When the circulation of the drilling fluid is stopped, the spring 4 pushes the plug 3 to move upwards, and the axial through hole is closed, so that the annular fluid can be prevented from flowing back into the sleeve.
