AI Technical Summary
In existing quick-release mechanisms for nail guns, the quick-release springs are difficult to assemble and are prone to deformation, affecting assembly efficiency and compatibility, and resulting in unstable seamless connection between the upper and lower nail holders.
An improved quick-release spring and quick-release trigger connection structure was designed. By setting a notch and a limiting protrusion on the quick-release trigger, combined with a fixing plate, the quick-release spring can be installed with less effort and accurately connected, avoiding deformation.
This achieves an efficient connection between the quick-release spring and the quick-release trigger, ensuring seamless connection between the upper and lower nail gun seats, and improving the quality and service life of the nail gun.

[0019] As shown in Figures 1-4 An improved structure of a nail gun quick release mechanism, comprising a quick release trigger 1 and a quick release spring 2 connected movably, the quick release trigger 1 is provided with connecting holes 11 on both sides, the quick release spring 2 is a metal spring shaped like "U", and is provided with two free ends 21 for connecting with the connecting holes 11 on the quick release trigger.
[0020] The quick release trigger is provided with a notch clamping groove 12 communicating with the connecting hole above both sides of the connecting hole 11, the width of the notch clamping groove 12 is greater than the outer diameter of the free end 21 of the quick release spring 2, both free ends 21 of the quick release spring 2 can be directly installed into the connecting hole 11 through the notch clamping groove 12 to realize the assembly of both, the whole assembly process is labor-saving and fast, and will not cause the deformation of the quick release spring 2, so as to effectively ensure the assembly precision of the quick release spring 2 and the quick release trigger 1, ensure the seamless butt joint of the upper and lower nail seats, and improve the quality and service life of the electric nail gun to a certain extent.
[0021] Here, in order to ensure the labor-saving and smooth installation of the quick release spring 2, the notch clamping groove 12 of the quick release trigger 1 is composed of a vertical straight section 12a and an inclined section 12b, and the two parts are smoothly transitioned through a circular arc section, so that when assembling, only the two free ends 21 of the quick release spring 2 need to be put into the notch clamping groove 12, and the free end 21 of the quick release spring 2 will automatically slide down to the position of the connecting hole 11 under the action of gravity to realize the assembly.
[0022] Here, in order to ensure the effectiveness of the connection between the free end 21 of the quick release spring and the connecting hole 11 after assembly, two limiting protrusions 211 are symmetrically arranged on the free end 21 of the quick release spring, the width of the limiting protrusion 211 is less than the outer diameter of the free end 21 of the quick release spring, and the maximum outer diameter of the positions of the two limiting protrusions 211 is greater than the width of the notch clamping groove 12. Since the width of the limiting protrusion 211 is less than the outer diameter of the free end 21 of the quick release spring, it is necessarily less than the width of the notch clamping groove 12, so that when assembling, only the two limiting protrusions 211 need to be clamped into the notch clamping groove 12 in a vertical state to ensure smooth clamping. After the free end 21 of the quick release spring 2 is slid into position, the whole quick release spring 2 is rotated, so that the two limiting protrusions 211 are transformed from a vertical state to a horizontal state, and the maximum outer diameter of the two limiting protrusions 211 is greater than the width of the notch clamping groove 12, so that the two limiting protrusions 211 in the horizontal state are effectively locked by the notch clamping groove 12, which fundamentally eliminates the problem of jumping out of the notch clamping groove 12 and ensures the effectiveness of the connection between the quick release spring 2 and the quick release trigger 1.
[0023] Here, in order to further ensure the connection effectiveness of the quick release spring 2, a pressing plate 3 is installed on the quick release trigger 2, the top and side of the pressing plate 3 cover the notch clamping groove 12, so as to limit the free end 21 of the quick release spring 2 to be always located in the connecting hole 11 of the quick release trigger 1.
[0024] The bottom of the pressing plate 3 is provided with an upper fixing hole, and the quick release trigger 1 is provided with a lower fixing hole 13, the upper and lower fixing holes are connected by screws to fixedly connect the quick release trigger 1 and the pressing plate 3 together. The material of the pressing plate 3 is one of plastic, rubber, metal or wood, which is selected according to the actual needs.
[0025] The tail of the pressing plate 3 extends rearward by a distance, which is equivalent to extending the overall lever length of the quick release handle 1, thereby reducing the torque for rotating the quick release handle 1 and achieving labor-saving operation.
[0026] The surface of the pressing plate 3 is provided with a ratchet 31 to facilitate finger force when rotating the pressing plate 3.
[0027] The above is only a preferred embodiment of the present application, and does not limit the application in any form. Any simple modification, equivalent change or modification made according to the technical principle of the present application to the above embodiments still belongs to the scope of the technical solution of the present application.
