Background
The nail shooter is a modern advanced fastening device, when the nail shooter is used, a firing pin rapidly moves forwards in a cartridge chamber seat, a tip part of the firing pin strikes the tail part of a nail shooting bullet, the nail shooting bullet explodes, and generated high-pressure gas pushes the nail to rapidly enter a basal body at the front end to complete a nail shooting process. Compared with the traditional fastening technology, the nail shooting device does not need to carry external energy sources such as electric energy, compressed air and the like, so that the nail shooting device is free from the tiredness of equipment such as electric wires, air compressors and the like, and the application range of the nail shooting device is greatly widened. Meanwhile, the device has the advantages of simplicity and convenience in operation, low labor intensity, firm and reliable connection and the like, and is widely applied to the connection of doors and windows, heat-insulation plates, pipelines, steel members and the like.
Because the intensity of the matrix is different, the shooting power needs to be adjusted in real time according to the intensity of the matrix in the actual use process. In the process of shooting the nail, the power of shooting is usually controlled by controlling the pressure relief amount of high-pressure gas, and if the pressure relief amount of the high-pressure gas in the process of shooting is zero, the power of shooting of the nail shooter reaches the maximum; if the pressure relief amount of the high-pressure gas is the maximum in the firing process, the firing power of the nail shooter can reach the minimum. Therefore, a technology for adjusting shooting power by controlling pressure relief is developed, for example, the prior art with Chinese patent publication No. CN109202811A discloses an adjustable power axial nail shooter in 2019, 1 month and 15 days, which comprises a nail tube and a firing pin sleeve, wherein the wall of the nail tube is provided with one or more pressure relief through holes; and the power adjusting device is arranged and can block the pressure relief through hole. This ail shooter can be under the prerequisite that does not change original equipment working method and effect, ingenious setting up a plurality of pressure release through-hole on the nail pipe wall, utilizes the cylinder end cap, stops up the pressure release through-hole of a certain quantity according to actual need to obtain the most suitable explosion power. However, in the patent, the pressure relief through hole is arranged in the silencing cover, so that the silencing cover needs to be completely disassembled and assembled once when the power is adjusted, and meanwhile, the cylindrical plug needs to be disassembled and assembled when the power is adjusted every time, so that the power adjusting process is complicated. In addition, because the sound damping cover is not positioned, the sound damping cover is easy to loosen due to wrong knob in the normal use process.
