Technical Field

[0001] The utility model relates to the field of lithium battery steel nail guns, in particular to a lithium battery steel nail gun with an adjustment function. Background Art

[0002] A nail gun is a nailing tool that uses electricity as power. It is a common power tool and the most in-demand power tool product. It is mainly used in the fields of construction, home improvement, medical treatment, etc., and is used to penetrate the surface of objects. With the development of society and the advancement of science and technology, the technology of high-efficiency brushless lithium-ion nail guns is becoming more and more mature. The main structure of the high-efficiency brushless lithium-ion nail guns currently on the market is similar. The key is that the accessories of the quick shift device at the core operation are different, which mainly depends on the manufacturer's functional tendency of the high-efficiency brushless lithium-ion nail gun.

[0003] The current lithium-ion nail guns mainly drive the firing pin to drive the nails out by pressurizing the cylinder. The firing frequency is usually fixed. However, when targeting some materials with lower hardness, such as wood, the impact force is extremely redundant, resulting in low working efficiency. It is difficult to adjust it according to the properties of the material to maximize the optimization of the tool performance. Utility Model Content

[0004] In order to overcome the problem that the current lithium-ion nail gun drives the firing pin to drive the nail out by pressurizing the cylinder, its shooting frequency is fixed. However, when targeting some materials with lower hardness, its impact force has great redundancy, resulting in low working efficiency.

Since the striker and the connecting seat are connected by the connecting bolt, they are easy to replace.

[0009] Preferably, a plurality of sets of fixed teeth are fixedly connected to the outer side of the firing pin, and the firing pin is slidably connected to the gun head. The air inside the cylinder is compressed by the piston and then released, so that the firing pin moves forward quickly, and the steel nails that push the nail plate upward are quickly ejected from the inside of the gun head.

When it rotates to the neutral zone, the pressure is released instantly to provide power for the impact.

[0011] Preferably, the adjustment component includes a compression spring, a sliding rod, a pressing plate, a limit plate and a limit block. A compression spring is arranged on the outside of the movable shaft. The sliding rod is slidably connected to the inside of the front end shell. The lower end of the sliding rod is fixedly connected to the pressing plate. The pressing plate is located at the upper end of the movable shaft. When the hardness of the nailed object is low, the compression spring drives the movable shaft to lift upward, and only the fixed shaft is engaged with the fixed teeth, thereby expanding the idle area, reducing the time for processing compressed air, and increasing the nail shooting frequency for greater practicality.

[0012] Preferably, the upper end of the sliding rod is fixedly connected to a limit plate, and the upper end of the front end housing is rotatably connected to a limit block.

[0013] Beneficial effects of the utility model:

[0014] 1. The air inside the pneumatic component is compressed by the driving component to provide the required power. The component can then be adjusted to cope with objects of different materials, increase the nail shooting frequency, and improve the practicality of the nail gun.

[0015] 2. When the hardness of the nailed object is low, the compression spring drives the movable shaft to lift upward, and only the fixed shaft is engaged with the fixed teeth, which expands the neutral area and reduces the time for handling compressed air. During normal use, press the limit plate downward and use the limit block to lock it. At this time, the pressing plate at the lower end of the sliding rod is pressed on the upper end of the movable shaft to engage with the fixed teeth to increase the air pressure to cope with objects with higher hardness. It can be more practical by adjusting the nail shooting frequency. BRIEF DESCRIPTION OF THE DRAWINGS
