Further, the N is 3 to 5. Preferably 3.

The value of N corresponds to the number of the faces of the multi-face gear and the number of the clamping arms. The more the clamping arms are, the firmer the clamping of the false tooth is relatively. However, in comparison with a multiple-face gear with the same diameter, the contact area between each face and the clamping arm is smaller as the number of faces is larger, and the tooth sum degree of the multiple-face gear and the clamping arm is smaller. Therefore, N is a reasonable value obtained by comprehensively considering the firmness degree and the stability degree (which are inversely related) of the tooth sum between the multi-face gear and the clamping arm, wherein 3 is an optimal value.
