Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority of Taiwanese Patent Application No. 110145795, filed on Dec. 8, 2021. FIELD The present disclosure relates to a hand tool capable of generating vibration during operation, and more particularly to a hand tool for reducing hand vibration. BACKGROUND An existing massage gun accelerates blood circulation and loosens muscles of a sore area through high frequency vibrations to give a massage. During the use of the massage gun, a human hand is required to hold the massage gun and position the massaging head of the massage gun at a location requiring massage. During the operation of the massage gun, high frequency vibration is continuously generated. Although the part requiring massage can be massaged, the hand holding the massage gun may be also vibrated simultaneously, easily causing hand injury or discomfort. SUMMARY The object of the disclosure is to provide a hand tool that can alleviate at least one of the drawbacks of the prior art. According to the disclosure, the hand tool for reducing hand vibration, including a casing, a driving module, a power module and a workplace. The casing includes a front section, a rear section, and a buffering section connected between the front and rear sections. The buffering section is made of an elastic material. The rear section is adapted for gripping. The driving module is disposed on the front section. The power module is disposed on the rear section, and is electrically connected to the driving module to supply electricity to the driving module. The workpiece is connected to the driving module, extends out of the front section, and is driven by the driving module to operate. BRIEF DESCRIPTION OF THE DRAWINGS Other features and effects of the disclosure will be clearly presented in the embodying manner with reference to the drawings, in which: FIG. 1 is a fragmentary perspective schematic view of an embodiment of the hand tool for reducing hand vibration according to the disclosure; FIG. 2 is another fragmentary perspective schematic view of the embodiment taken from another angle; FIG. 3 is a perspective view of a buffering section of the embodiment; FIG. 4 is an exploded perspective view of the buffering section; FIG. 5 is another perspective view of the buffering section; FIG. 6 is another exploded perspective view of the buffering section; FIG. 7 is a schematic side view of the embodiment, illustrating a handle of the embodiment in an extended state; FIG. 8 is a schematic side view illustrating the handle in a shortened state; FIG. 9 is a view similar to FIG. 7, but illustrating an adjustable pivot angle of the handle; FIG. 10 is a perspective view of an expansion module of the embodiment; FIG. 11 is an exploded perspective schematic view of the expansion module; FIG. 12 is a perspective schematic view of the embodiment; FIG. 13 is an exploded schematic side view illustrating a state of an extension member of the expansion module before being combined with the handle; and FIG. 14 is a combined schematic side view of FIG. 13.
