[0037] A further optimized solution is that the first transmission assembly includes a transmission rod 7, which is rotatably connected to the inner wall of the outer cylinder 1, and one end of the transmission rod 7 close to the protruding end of the inner cylinder 2 is fixedly connected to a first threaded head 8, a threaded groove 9 is provided on the outer wall of the inner cylinder 2, and the first threaded head 8 is threadedly matched with the threaded groove 9, and a pair of first limit blocks 10 are fixedly connected to the opening of the outer cylinder 1 close to the protruding end of the inner cylinder 2, and a pair of first limit grooves 11 are provided on the side wall of the inner cylinder 2, and the pair of first limit blocks 10 are slidably matched one by one in the pair of first limit grooves 11.
