[0011] As a further solution of the present invention, the fixing fixture adopts a double-threaded fixing fixture.
[0012] As a further solution of the present invention, the expansion plate is arranged in parallel inside the flared sleeve, which is conducive to the expansion plate pushing out of the flared sleeve, so that the flared sleeve can be expanded and contracted outward.
[0013] As a further solution of the present invention, the transmission push cylinder and the transmission connecting rod are arranged at the same level inside the expansion plate, ensuring that the transmission push cylinder can reduce power loss when pushing the expansion plate through the transmission connecting rod to move.
