DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-8 The utility model provides the following technical scheme: a double-insurance fixed nail device, which comprises a main body 1, a movable shell ejection cover 2, a sound attenuation cover 3, a firing tube 4, a firing pin body 5, a firing spring 6, a firing pin seat spring 7, a safety pin spring I 8, a safety pin I 9, a limit pin 10, a connecting pin 11, a firing pin 12, a firing pin seat 13, a shell ejection spring 14, an adjusting ring 15, the adjusting ring 15 comprises a limit screw groove 151, a safety pin groove 152, a safety pin hole I 153 and a safety pin hole II 154, a limit screw hole 16 is arranged on the surface of the lower end of the movable shell ejection cover 2, a safety pin counterbore 17 is formed in the surface of the lower end of the movable shell ejection cover 2, a limit screw 18 is arranged in the limit screw hole 16, a safety pin spring II 19 is arranged in the safety pin counterbore 17, and a safety pin II 20 is fixedly connected to the end of the safety pin spring II 19.

[0024] In the embodiment, an external safety device is added without changing the structure of the original fixed nail device, the external safety device is composed of the adjusting ring 15, the limit screw 18, the safety pin spring II 19 and the safety pin II 20, the safety pin II 20 can be in the safety pin hole I 153 by rotating the adjusting ring 15, manual locking can be realized, the safety of the fixed nail device that cannot be locked in the prior art is more obvious, the safety accidents caused by misuse can be effectively prevented, and the safety and reliability of the utility model are improved by rotating the adjusting ring 15 to make the safety pin II 20 in the safety pin hole II 154, which facilitates operation.

[0025] Specifically, the inner diameter of the adjusting ring 15 is larger than the diameter of the lower end of the movable extraction sleeve 2, so that the adjusting ring 15 is movably installed on the outer surface of the lower end of the movable extraction sleeve 2, thereby facilitating the rotation of the adjusting ring 15.

[0026] Specifically, the limiting screw groove 151, the safety pin groove 152, the safety pin hole one 153 and the safety pin hole two 154 are integrally punched, thereby facilitating the molding and saving the processing cost.

[0027] Specifically, the diameter of the safety pin hole one 153 is smaller than that of the safety pin hole two 154, so that the safety pin two 20 has a shorter protruding length when located in the safety pin hole one 153 than when located in the safety pin hole two 154, thereby facilitating the locking purpose.

[0028] Specifically, the main body 1 is provided with a limiting step 21, and the limiting step 21 is arranged to facilitate the limiting of the main body 1 by the safety pin spring two 19, so that the main body 1 cannot slide in the movable extraction sleeve 2 after being locked.

[0029] Specifically, the safety pin two 20 includes a step one 201 and a step two 202, and the safety pin two 20 contacts the safety pin hole one 153 and the safety pin hole two 154 through the step one 201 and the step two 202. Since the diameter of the safety pin hole one 153 is smaller than that of the safety pin hole two 154, the overall protruding distance of the safety pin two 20 is short when the step one 201 is located in the safety pin hole one 153, so that the safety pin two 20 is located within the range of the limiting step 21 at this time, that is, it is locked. When the step two 202 is located in the safety pin hole two 154, the overall protruding distance of the safety pin two 20 is longer, and the safety pin two 20 as a whole moves out of the limiting step 21 at this time, that is, it is unlocked.

[0030] The working principle or use process of the utility model discloses: by main body 1, movable shell ejection cover 2, sound attenuation cover 3, launching tube 4, firing pin body 5, firing spring 6, firing pin seat spring 7, safety pin spring one 8, safety pin one 9, limit pin 10, connecting pin 11, firing pin 12, firing pin seat 13 and shell ejection spring 14 constitute the nail fixing device, when using, first, the nail is placed in the launching tube 4, then through the main body 1 of pressing down activation burst mechanism (firing pin body 5, firing spring 6, firing pin seat spring 7, safety pin spring one 8, safety pin one 9, limit pin 10, connecting pin 11) makes the impact motion of firing pin 12, realizes the installation of nail, under the premise of not changing the original nail fixing device structure, the application increases an external safety device, the external safety device is composed of adjusting ring 15, limit screw 18, safety pin spring two 19, safety pin two 20, safety pin spring two 19 and safety pin two 20 are located in safety pin sink hole 17, limit screw 18 is located in limit screw hole 16, by pressing safety pin two 20, adjusting ring 15 can be rotated, safety pin two 20 moves in the range of safety pin groove 152, rotating adjusting ring 15 can make safety pin two 20 rest in safety pin hole one 153 or safety pin hole two 154, safety pin spring two 19 can support and press safety pin two 20, because the diameter of safety pin hole one 153 is less than the diameter of safety pin hole two 154, therefore, the step one 201 of safety pin two 20 is located in safety pin hole one 153, and the self-probing distance is short, so the end of safety pin two 20 at this time is located in the range of limit step 21, that is, it is locked, the step two 202 of safety pin two 20 is located in safety pin hole two 154, and the self-probing distance is relatively long, so the end of safety pin two 20 at this time is moved out of the range of limit step 21, that is, it is unlocked, compared with the nail fixing device of prior art only having internal safety, the safety is more remarkable, and the safety accident caused by misuse can be effectively prevented.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and not for limiting the utility model, the description selects and specifically describes these embodiments, in order to better explain the principle and practical application of the utility model, so that the person skilled in the art can well understand and utilize the utility model, although the foregoing embodiments of the utility model are described in detail, for those skilled in the art, still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to some technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
