[0065] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0066] This application provides a first embodiment of a nail shooter. Figure 1 and Figure 2 .

[0067] The nail shooter in this embodiment includes: a nail shooter body A, a holding mechanism B, a firing mechanism C and a return spring 18; the nail shooter body A is a hollow tubular structure, and the front end of the nail shooter is used to place the nail 16; the holding mechanism B is sleeved on the rear end of the nail shooter body A; the firing mechanism C is arranged inside the holding mechanism B, and the front end is connected to the rear end of the nail shooter body A, and the rear end is connected to the holding mechanism B; the return spring 18 is sleeved on the outer wall of the firing mechanism C, and the front end is connected to the rear end of the nail shooter body A, and the rear end is connected to the rear end of the firing mechanism C; the front end of the nail 16 is provided with a screw hole 161 for installing a rescue component.

[0068] The hollow tubular nail driving device body A can not only accommodate the nails 16, but also is convenient for a person to hold when operating with one hand.

[0069] The holding mechanism B can be any of the various existing structures, and those skilled in the art can select one according to their needs, as long as it can cooperate with the nail shooter body A to achieve holding. No specific limitations or detailed descriptions are made here.

[0070] The firing mechanism C may be the firing mechanism C in an existing nail shooter, and will not be described in detail here.

[0071] It can be understood that the rescue component in this embodiment can be a rescue rope or a fixed screw for rescue and other components. Those skilled in the art can set it according to specific needs, which will not be described here.

[0072] In this embodiment, the rear end of the nail shooter body A with a hollow tubular structure is sleeved with a holding mechanism B, and the holding mechanism B is also connected to the firing mechanism C. A return spring 18 is sleeved on the outer wall of the firing mechanism C. In this way, when in use, the thumb presses the rear end of the protective cover, and the four fingers hold the holding mechanism B tightly, keeping the nail shooter axially vertical to the base and pressing forward. The holding mechanism B and the firing mechanism C will compress the return spring 18 and move forward. After the guide tube 13 of the firing structure presses against the nail 16, the firing pin seat 10 of the firing structure stops moving forward. At this time, the holding structure and the sleeve 3 continue to overcome the forward movement of the firing spring 4. When the third boss 32 in the sleeve 3 presses the brake pin 6, the firing spring 4 is released, and the firing pin 12 impacts the nail 16 forward, thereby generating high-pressure gunpowder gas to shoot the nail 16. After the firing is completed, the firing mechanism C and the holding mechanism B reset and move backward under the elastic force of the return spring 18, so that the nail shooter body A returns to the state before firing and is ready for the next firing. The entire process can be operated with one hand, which is easy to use. By introducing the construction nail gun into the field of emergency rescue, the time for tightening the rescue rope at the rescue site is shortened, and safety and reliability are improved. The nail gun in this application has a compact and reasonable structure, and is overall light and short, thereby solving the technical problems of existing nail guns that are large in size, heavy in weight, inconvenient to carry, and inconvenient to operate during emergency rescue.

[0073] The above is a first embodiment of a nail shooter provided by the embodiment of the present application. The following is a second embodiment of a nail shooter provided by the embodiment of the present application. For details, please refer to Figures 1 to 5 .

[0074] A nail shooter in this embodiment includes: a nail shooter body A, a holding mechanism B, a firing mechanism C and a return spring 18; the nail shooter body A is a hollow tubular structure, and the front end of the nail shooter is used to place a nail 16; the holding mechanism B is sleeved on the rear end of the nail shooter body A; the firing mechanism C is arranged inside the holding mechanism B, and the front end is connected to the rear end of the nail shooter body A, and the rear end is connected to the holding mechanism B; the return spring 18 is sleeved on the outer wall of the firing mechanism C, and the front end is connected to the rear end of the nail shooter body A, and the rear end is connected to the rear end of the firing mechanism C; the front end of the nail 16 is provided with a screw hole 161 for installing a rescue component.

[0075] Specifically, if Figure 2As shown, the firing mechanism C in this embodiment includes: the firing mechanism C includes: a pressure cap 2, a sleeve 3, a guide tube 13, a firing pin 12, a hammer 5, a firing spring 4, a firing pin seat 10 and a limiting component; the pressure cap 2 is sleeved on the rear end of the sleeve 3; the sleeve 3 is arranged in the holding mechanism B, and a return spring 18 is sleeved on the outer wall of the sleeve 3; the firing pin seat 10 is arranged in the sleeve 3, and the rear end of the firing pin seat 10 abuts against the sleeve 3; the hammer 5 is movably arranged in the firing pin seat 10 through the limiting component; the firing pin 12 is arranged in the guide tube 13, and the front end of the guide tube 13 is connected to the nail shooter body A, and the rear end is connected to the front end of the firing pin seat 10; the firing pin 12 is connected to the hammer 5; the front end of the firing spring 4 is connected to the hammer 5, and the rear end is connected to the pressure cap 2.

[0076] The front end of the firing spring 4 is connected to the hammer 5, and the rear end is connected to the sleeve 3. The firing pin seat 10 is arranged in the sleeve 3, and the rear end of the firing pin seat 10 is in contact with the sleeve 3. The hammer 5 is arranged in the firing pin seat 10, and the hammer 5 is connected to the firing pin 12. The firing pin 12 is located in the guide tube 13, and the guide tube 13 is connected to the nail shooter body A. In this way, the firing pin 12 in the guide tube 13 is aligned with the nail 16. When the sleeve 3 moves with the holding mechanism B, the firing spring 4 is compressed. When the sleeve 3 moves to the limiting component, the third boss 32 in the sleeve 3 pushes the brake pin 6. The brake pin 6 sinks and the limit is released. The hammer 5 and the firing pin 12 are released, and under the thrust of the firing spring 4, they quickly impact forward to shoot the nail 16.

[0077] It is understood that the hammer 5 and the firing pin 12 can be directly connected or connected as shown in FIG. Figure 2 As shown, the hammer 5 and the firing pin 12 are indirectly connected through the connecting handle 9. When the hammer 5 and the firing pin 12 are connected through the connecting handle 9, a positioning pin 8 is provided on the connecting handle 9. The positioning pin 8 is used to connect the firing pin 12, the connecting handle 9 and the hammer 5.

[0078] The reset spring 18 is connected to the sleeve 3. When the firing is completed, the reset spring 18 drives the sleeve 3 to complete the reset of the firing mechanism C.

[0079] Specifically, the limiting component in this embodiment includes: a brake pin 6, a brake pin spring 7 and a limiting screw 22. Figure 3FIG. 1 is a schematic diagram of the structure of the hammer 5 and the schematic diagram of the structure of the firing pin seat 10. In this embodiment, the hammer 5 is provided with a cylindrical hole for installing the brake pin 6. The brake pin spring 7 is provided in the cylindrical hole. The brake pin 6 is then assembled on the brake pin spring 7. The brake pin spring 7 and the brake pin 6 together serve as a brake limiter. The non-assembly surface of the brake pin 6 (the assembly surface of the brake pin 6, i.e., the end surface where the brake pin 6 and the brake pin spring 7 contact, the non-assembly surface being the end surface opposite the assembly surface) is provided with a stepped first boss 62 and a second boss 63. The first boss 62 corresponds to the high-level groove 1021 of the brake pin 6 groove in the firing pin seat 10, and the second boss 63 corresponds to the low-level groove 1022 in the brake pin 6 groove. The hammer 5 is set in the firing pin seat 10 by the cooperation between the first boss 62 and the high-level groove 1021, and the cooperation between the second boss 63 and the low-level groove 1022. The low-level groove 1022 and the high-level groove 1021 are connected through. The limiting screw 22 is arranged on the outer side wall of the hammer 5, so that the limiting screw 22 has a cylindrical pin and is movably connected to the sleeve 3 for limiting and resetting.

[0080] It can be understood that, in order to facilitate the movement of the brake pin 6 , a convex spherical surface 61 is provided at the front end of the first boss 62 of the brake pin 6 .

[0081] It should be noted that if Figure 3 As shown, the limiting screw 22 can be set perpendicular to the axis of the brake pin 6, and the number of brake pins 6 can be two, and the two limiting screws 22 are distributed in a straight line. It is understood that the number and arrangement direction of the limiting screws 22 are merely illustrative examples, and those skilled in the art can adjust them as needed.

[0082] It is understandable that in order to prevent the hammer 5 from rotating, a limiting pin groove 104 for limiting the limiting screw 22 is provided on the firing pin seat 10.

[0083] Specifically, see Figure 5 and Figure 2 As shown, in this embodiment, the sleeve 3 is provided with a plurality of third bosses 32 for engaging with the brake pin 6. The third bosses 32 are arranged in a discontinuous circumferential pattern, and one of the third bosses 32 is axially aligned with the convex spherical surface 61 of the brake pin 6. A hook edge 35 is provided on the side wall of the sleeve 3, which engages with the stop screw 22. The rear end of the firing pin seat 10 is provided with a plurality of flanges 103, which are arranged in a discontinuous circumferential pattern and abut against the third bosses 32. Initially, the flanges 103 abut against the third bosses 32. As the sleeve 3 moves forward, the third bosses 32 in the sleeve 3 contact the stop member in the firing pin seat 10, releasing the stop member from being retained.

[0084] Specifically, if Figure 1 and Figure 2As shown, the holding mechanism B in this embodiment includes: the holding mechanism B includes: a handle 19, a handle cover 20 and a protective cap 21; the handle 19 is a tubular hand handle 19, and the front end of the handle 19 is connected to the rear end of the nail shooter body A, and the rear end is connected to the handle cover 20; the handle cover 20 is located between the protective cap 21 and the pressure cover 2; the protective cap 21 is sleeved on the handle cover 20.

[0085] The protective cap 21 is made of rubber and is sleeved on the rear end of the gripping mechanism B. During operation, the rubber protective cap 21 plays a role in cushioning, improving grip comfort, aesthetics, and increasing friction.

[0086] Furthermore, for easier gripping, the outer wall of the handle 19 in this embodiment is provided with anti-slip stripes, which can not only prevent bouncing but also prevent falling. The material of the handle 19 can be selected from aluminum alloy. It is understood that those skilled in the art can also set it to other materials, which will not be described in detail here.

[0087] Furthermore, in order to play a buffering role when the inside and outside impact each other, especially after the firing nail 16 is fired, the firing mechanism C recoils the nail shooter and impacts backward, a buffer pad 1 is provided between the pressure cover 2 and the handle cover 20 to play a buffering role.

[0088] The material of the buffer pad 1 can be rubber or other materials, and those skilled in the art can choose according to needs.

[0089] Furthermore, in order to simplify the structure and reduce the weight, in this embodiment, the existing dust cover and the silencer pipe are combined into one to form a dust and silencer sleeve 15 .

[0090] In order to ensure that the nail shooter can better contact the substrate during use, the front end of the dustproof and silencer sleeve 15 is arc-shaped.

[0091] It can be understood that the plug 11 can press and fix the guide tube 13. The front end of the plug 11 has a boss that cooperates with the inner wall of the nail shooter connecting tube 17. There is a through hole in the middle of the front end and an internal thread at the rear end. The guide tube 13 is connected to the firing pin seat 10 through the internal thread at the rear end.

[0092] It is understood that the main body A of the nail shooter in this embodiment includes a connecting tube 17 and a barrel 14. The barrel 14 is the front end portion of the main body A of the nail shooter, i.e., the portion where the nails 16 are placed. The barrel 14 has a through hole in the middle. The front end of the through hole is used to load the nails 16, and the rear end of the through hole cooperates with the guide tube 13. The outer surface of the front end is threaded and connected to the dust-proof and silencer sleeve 15, and is provided with several through holes for silencer. The rear end is threaded and connected to the connecting tube 17. The connecting tube 17 is a tubular structure that serves to connect the front and rear ends. The front end has an internal thread connected to the barrel 14, and the rear end has annular bosses on the inside and outside of the longitudinal direction. The inner boss is used to limit the boss of the plug 11, and the outer boss cooperates with the inner boss at the front end of the handle 19.

[0093] For ease of understanding, the specific motion principle of the nail shooter in this embodiment is described below:

[0094] When in use, it is operated with one hand. The thumb presses the rear end of the protective cap 21, and the other four fingers hold the handle 19 tightly, keeping the nail gun axially perpendicular to the base and pressing forward. At this time, the handle 19 and the internal firing mechanism C will compress the return spring 18 and move forward together; after the front end of the guide tube 13 abuts the rear end surface of the nail 16, the guide tube 13 and the firing pin seat 10 are supported, and the handle 19 and the sleeve will continue to compress the return spring 18 and the firing spring 4 and continue to move forward. When the third boss 32 of the sleeve 3 moves forward to the brake pin groove 102 of the firing pin seat 10, it presses the brake pin 6 positioned by the second boss 63 of the groove. The brake pin 6 sinks to release the forward limit, and the hammer 5 and the firing pin 12 quickly strike forward under the thrust of the spring to drive the nail 16 (see the schematic diagram of the firing state). Figure 6 The gunpowder at the rear end of the nail 16 is struck and ignites, and the high-pressure gunpowder gas pushes the nail 16 with the rescue rope fastened to it forward. When the rear end of the nail 16 passes through the through hole for silencing on the barrel 14, part of the gas will enter the closed cavity contained by the dust-proof and silencer sleeve 15 and the barrel 14, thereby silencing the sound. After that, the nail 16 is violently shot into the base body and is fixed. Subsequently, the guide tube 13 and the firing pin seat 10 recoil under the push of the gunpowder pressure, and the recoil is stopped when the front end boss of the plug 11 presses against the boss inside the connecting tube 17; when the handle is not pressed forward, the sleeve 3 will reset and move backward under the elastic force of the reset spring 18, and then the hook edge 35 at the front end of the sleeve 3 will hook the limiting screw 22, pulling the hammer 5 and the firing pin 12 to move backward inside the firing pin seat 10, and the first boss 62 of the brake pin 6 is stuck in the high-level groove 1021 and moves backward. When it moves backward to the low-level groove 1022, the brake pin 6 bounces up under the elastic force of the brake pin spring 7, and the second boss 63 is stuck in the low-level groove 1022 and limited. The third boss 32 at the front end of the sleeve 3 presses against the flange 103 of the firing pin seat 10 to prevent further backward movement. The entire nail shooter returns to its original position and can be fired.

[0095] The nail gun provided in the embodiment of the present application has the following advantages compared to the prior art:

[0096] 1) The nail gun can be operated with one hand, so it can be used in emergency rescue, greatly shortening the time of fastening the rescue rope at the rescue site and improving the safety and reliability of rescue;

[0097] 2) The overall layout of the nail gun is compact, the structure is small and reliable, and it is easy to carry;

[0098] 3) The limiting screw 22 is installed on the hammer 5, which simplifies the structure and reduces the weight;

[0099] 4) The dust cover and silencer sleeve are combined into one, which greatly reduces the weight and simplifies the structure;

[0100] 5) The original disconnected contact connection between the firing pin seat 10 and the sleeve 3 facilitates assembly and disassembly.

[0101] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
