[0065] Specifically, the mounting groove 31 is provided in the impeller insert 3, and the mounting groove 31 extends along the axial direction of the impeller insert 3, that is, the mounting groove 31 is vertically arranged in the impeller insert 3. Such arrangement facilitates the installation of the spring pin 4 in the mounting groove 31, so that the spring pin 4 remains in a vertical state, so that the spring pin 4 cooperates with the fixing groove 22.

[0066] A mounting hole 32 is opened on one side of the mounting groove 31, and the opening direction of the mounting hole 32 is perpendicular to the axial direction of the mounting groove 31, that is, the mounting groove 31 is vertically arranged along the axial direction of the impeller insert 3, and the opening direction of the mounting hole 32 is horizontally arranged, so that the spring pin shaft 4 can move through the mounting hole 32.

[0067] Furthermore, the elastic sheet 41 is disposed on a side of the first pin shaft 42 away from the output shaft 21 , and is bent from the first pin shaft 42 and extends to the inner wall of the mounting groove 31 .
