The adjusting means includes a connecting spindle having a first end thereof fixed in the connecting portion and a second end thereof formed with a connector inserted into the fixing hole of the head, and a fastening member threaded through a screw hole defined at one side of the fixing seat and extending into the fixing hole. A tip end of the fastening member formed with a cone surface is correspondingly abutted against an inclined surface formed around an annular groove defined around the connector.
