Abstract

The present invention discloses a hybrid nail gun, which comprises a power component and a drive component, wherein the power component is driven by the drive component, and the drive component comprises at least a gas driven device and an electric driven device. The present invention may be used as a pneumatic nail gun when it can be connected to a gas source. The present invention may use a power source to drive the power component to complete a nailing action when it is impossible or inconvenient to connect a gas source. The present invention can flexibly adapt to different work scenarios without the need to change different types of nail guns. Therefore, the work efficiency is improved and the cost is reduced.

First claim

The invention claimed is:

1. A hybrid nail gun, comprising a power component and a drive component, the power component being driven by the drive component, characterized in that the drive component comprises pneumatic motor and an electric motor, the pneumatic motor comprises a gas source connection port and a pneumatic motor housing, and the pneumatic motor and the electric motor are connected in series;
wherein a clutch component is provided between the pneumatic motor and the electric motor, and
the clutch component comprises a clutch switch configured to control separation and cooperation between the pneumatic motor and the electric motor;
wherein the drive component further comprises a reduction box and an output member provided at the reduction box, and the reduction box is connected to the electric motor, or to the pneumatic motor, and
the output member is brought into contact with the power component and drives the power component to move; the pneumatic motor is connected to the electric motor, and the output member is a cam.

2. The hybrid nail gun of claim 1 , characterized in that the power component comprises a fixed shaft, a power spring, and a slider, the power spring is sleeved on the fixed shaft, one end of the power spring is connected to the fixed shaft, and the other end of the power spring is connected to the slider.

3. The hybrid nail gun of claim 2 , characterized in that the cam is configured to rotate under the drive of the drive component, to drive the slider to slide along the fixed shaft, such that the power spring is in a compressed state.

4. The hybrid nail gun of claim 3 , characterized in that the slider is provided with a recessed opening configured to enable the cam to be separated from the slider, so as to release the power spring from the compressed state.

5. The hybrid nail gun of claim 4 , characterized by further comprising a nail gun housing and a magazine, wherein the power part, the drive part, and the magazine are all fixed on the nail gun housing; the magazine comprises a nailing opening; and a fastening nail in the magazine is pushed out of the magazine through the nailing opening under an acting force of the slider.

6. The hybrid nail gun of claim 1 , characterized in that the power component comprises a shaft rod, and a plurality of ribs are provided on the shaft rod.

7. The hybrid nail gun of claim 6 , characterized in that a plurality of cam teeth are provided on the cam, the cam is brought into contact with the ribs via the cam teeth, and the cam is configured to rotate under the drive of the drive component, to drive the shaft rod to move through acting forces of the cam teeth on the ribs.

8. The hybrid nail gun of claim 7 , characterized in that a toothless part is provided on the cam, and the toothless part is configured such that during the rotation of the cam, the rib loses support from the cam tooth when the toothless part moves to the position of the rib, thereby releasing the shaft rod.

9. The hybrid nail gun of claim 1 , characterized in that the drive component comprises a gas cylinder, and the drive component comprises an electric inflation pump.

10. The hybrid nail gun of claim 9 , characterized in that the gas source connection port is in communication with the gas cylinder, the electric inflation pump is in communication with the gas cylinder, a first one-way valve is provided at a joint part of the gas source connection port and the gas cylinder, and a second one-way valve is provided at a joint part of the electric inflation pump and the gas cylinder.

11. The hybrid nail gun of claim 10 , characterized in that the first one-way valve is configured such that gas is capable of entering the gas cylinder from the gas source connection port but is not capable of returning to the gas source connection port from the gas cylinder.

12. The hybrid nail gun of claim 10 , characterized in that the second one-way valve is configured such that gas is capable of entering the gas cylinder from the electric inflation pump but is not capable of returning to the electric inflation pump from the gas cylinder.

13. The hybrid nail gun of claim 12 , characterized in that the first one-way valve and the second one-way valve have the same structure, comprising a gas valve cavity, a one-way valve spring, and a one-way valve ball; the gas valve cavity is shaped to form cylinders with unequal diameters; a diameter of the gas valve cavity at a non-ventilation end is smaller than a diameter thereof at a ventilation side; the one-way valve spring is provided at the ventilation end of the gas valve cavity; the one-way valve ball is provided at the non-ventilation end of the gas valve cavity; and a diameter of the one-way valve ball is greater than a diameter of the gas valve cavity at the non-ventilation end.
