Abstract

The present invention provides a spontaneous electric energy storage hand tweak torch, comprising a lamp cap and a cylindrical casing. The casing comprises a front casing and a rear casing capable of being bi-directionally tweaked about an axis. The lamp cap is fixed on the front casing. The interior of the front casing is provided with an electric generator, an energy storage element, a circuit board and a control switch. The exterior of the front casing is provided with a push button corresponding to the control switch. The output end of the electric generator is connected with the input end of the circuit board via a lead. The output end of the circuit board is connected with the energy storage element. The rotating shaft of the electric generator is connected with the rear casing via a gear set. The present invention has a simple and compact structure as well as a regular and uniform profile. Besides, it is convenient to operate and therefore saves labor. Consequently, it has a very prominent operation effect.

Claims
