In use, the finger rest 14 is fundamentally different from the handle assembly 12 in that: 1. the holding modes are different, the finger hooking part 141 of the finger support body 140 is only hooked by one or two fingers, if the finger hooking part 141 is only hooked by a middle finger, the tiger mouth of the palm is positioned at the rear part of the finger support body 140 and is in frictional contact with the lower part of the handle main body 11, the index finger extends and is attached to one side of the handle main body 11, the thumb is attached to the other side of the handle main body 11, the middle finger is hooked on the finger hooking part 141, and the ring finger and the little finger are curled and positioned below the finger support body 140; the handle body 120 can be grasped by the entire palm. 2. The two are different in size, the finger rest 14 is very small in size, and the handle body 120 is large in size.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
