Abstract: A nailing apparatus, comprising: a support mechanism, and an energy storage mechanism and an energy storage driving mechanism both provided in the support mechanism, wherein the energy storage driving mechanism comprises a power component, an eccentric component connected to the power component and a linear movement component connected to the eccentric component, and the power component comprises a driving electric motor and a step-down gear installed on an output shaft of the driving electric motor; a nailing driving mechanism, wherein the energy storage driving mechanism drives the nailing driving mechanism to hammer nail to drive the nail into a base material.

Abstract: With respect to a defect that a large-size capacitor is required to implement voltage multiplication in the prior art, the present invention provides a power-type voltage-multiplying driving circuit capable of overcoming the defect. An alternating current power supply J1, a unidirectional conducting element D1, and a charge storing element C are connected in series to form a charging circuit for charging the charge storing element C. A parallel circuit formed by the charge storing element C and the unidirectional conducting element D3 is connected in series to the alternating current power supply J1, a load R, and a switch element SCR to form a load driving circuit for performing voltage multiplication driving on the load R.

Abstract: An electromagnetic nail gun with a lever, comprising a handle for holding the nail gun and triggering the operation of the nail gun, an electromagnetic lever driving device for driving nails with variable speeds through the movement of the lever, wherein electromagnetism is used as driving force, a firing pin slideway for allowing the lever to move therein, and a muzzle magazine assembly for loading nails inside. The present invention uses the magnetism as driving force directly and then applies the lever and variable speed drive to launch nails. Therefore, the structure of the present invention is very simple, light, the manufacture cost is decreased drastically, vibration and noise when used are quite little, very convenient to operate, dispense with the air compressor, easy to carry around.
