[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 As shown, a quick-release structure for a lithium battery-powered impact tool gun head includes a gun body 1, with a nail gun head 3 slidably connected to one end of the top of the gun body 1, and a nozzle 2 fixed to the front end of the nail gun head 3 by a latch 201.
[0024] The nail gun head 3 has a nail ejection guide groove inside. The top of the gun body 1 is aligned with the nail ejection guide groove and has a ballistic track 4. The ballistic track 4 is used for the steel nail to pass through, so that the steel nail can enter the nail ejection guide groove inside the nail gun head 3 through the ballistic track 4 and be shot forward. The top of the gun body 1 is provided with a dust baffle 5 on one side of the ballistic track 4. One end of the nail gun head 3 is slidably connected to the inside of the ballistic track 4. The top of the nail gun head 3 has a slope 302 on one side. The top of the nail gun head 3 is provided with a limiting groove 301 near the slope 302.
[0025] The dust baffle 5 is fixed to the top of the gun body 1. The side surface of the dust baffle 5 is slidably connected to the ballistic 4 with a buckle 6. The bottom of the buckle 6 penetrates the inside of the ballistic 4. A spring 7 is sleeved on the surface of the buckle 6. The bottom of the spring 7 is located at the top of the ballistic 4 and is compressed or expanded. When the nail gun head 3 slides into the ballistic 4, the inclined surface 302 contacts the bottom of the buckle 6 and pushes it upward. The nail gun head 3 continues to slide forward in the ballistic 4. The buckle 6 slides downward and the bottom of the buckle is inserted into the limiting groove 301 and engaged with it.
[0026] When in use, the nozzle 2 is pressed against the surface of the workpiece to be hit. At this time, the nail gun head 3 is located inside the ballistic 4 and moves towards the dust baffle 5. The inclined surface 302 on one side of the top of the nail gun head 3 is pressed against the bottom of the buckle 6 and then pushed upward. When the buckle 6 is pushed upward, it forces the 8 to deform and compress. When the nail gun head 3 continues to move towards the dust baffle 5 inside the ballistic 4, the buckle 6 is offset from it by the inclined surface 302, and then slides down into the inside of the nail gun head 3 under the action of the 8, forming a snap-fit state with the nail gun head 3, locking the nail gun head 3 inside the ballistic 4, and preventing the nail gun head 3 from slipping out during use.
[0027] When replacing the rivet gun head 3 with different functions, the top of the buckle 6 can be manually pulled upward to force the 8 to compress, causing the bottom of the buckle 6 to exit the limiting groove 301 and separate from it. Then, the original rivet gun head 3 can be quickly disassembled and replaced with other rivet gun heads 3 with different functions. This structure does not require tools to disassemble the rivet gun head 3 with different functions, and does not generate too many screws during disassembly. The disassembly and replacement process is simple and quick.
[0028] It should be noted that when the bottom of the buckle 6 is inserted into the limiting groove 301, there is a gap between it and one side of the limiting groove 301, so that the nail gun head 3 can slide when it is pressed to prepare to strike.
[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Additionally, in the accompanying drawings of this utility model, the fill patterns are merely for distinguishing layers and do not constitute any other limitation.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
