Benefits of technology

This innovation relates to a small safe hamper that can be easily carried around or stored without causing damage from accidental impact. It consists of two parts - one part contains the hamber while another part holds the battery case. By pressing down onto either side when activated, both components expand outward due to their own elasticity. Once they have reached certain temperatures (the right amount), there'll just happen to release energy back into them again. Afterwards, if needed for more powerful strokes, the batteries may still work properly even though some were already dead beforehand.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the design for an impacting device called ahammer that can hit objects effectively without being too heavy or bulky at once while also having enough rigidity during use. Additionally, these devices have long handles making them difficult to transport safely due to their size.

Abstract

The invention relates to a labor-saving safety hammer comprising a hammerhead and a handle. The hammerhead comprises a top seat and a sleeve fixed on the top seat; the wall of the sleeve is made of a heat conduction material, and heating coils are arranged inside the sleeve wall; the axis of each heating coil coincides with that of the sleeve; each heating coil is electrically connected to an alternating power supply located inside the top seat; the alternating power supply is electrically connected to a control switch arranged on the handle; a power spring made of memory alloy is arranged on the axis inside the sleeve with one end fixed to the top seat, and a hammer piece is fixed to the other end of the power spring and can slide along the sleeve wall. The hammer can provide strong ramming force even though being light in self weight and small in size, is safe to use and cannot cause injury to human bodies.
