[0002] A chain belt nail gun, also known as a screw nail gun, is a new type of high-efficiency automatic power tool. It is powered by an electric drill to achieve the whole process of automatically feeding and screwing chain belt nails. This tool has a wide range of applications in many fields, especially in the decorative connection of materials such as light steel keels, gypsum boards, wooden boards, and thin steel plates.

[0003] Among them, the head part of the chain belt nail gun is a key component for installing, conveying chain belt nails, and tightening screws. At present, the head parts of most chain belt nail guns on the market are integrally designed with the body, and there are deficiencies in terms of maintenance convenience, adaptability, and easy cleaning.

[0004] The above content is only used to assist in understanding the technical solution of the present application, and does not represent an admission that the above content is the closest prior art to the present application. Summary of the Invention

[0005] Based on this, the present application provides a quick-release structure for the head of a chain belt nail gun to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve its technical problems is: a quick-release structure for the head of a chain belt nail gun, comprising: a nail gun main body including a housing, an opening groove is formed at the top of the housing, locking parts are arranged on both sides of the opening groove, an activity space is formed on the nail gun main body, and the locking parts are arranged in the activity space; a head part, sliding in the activity space, on which an unlocking button is installed, and the unlocking button is used to lock or unlock the head part; the locking part includes: a guiding block, arranged obliquely upward, forming a guiding inclined surface for providing guidance to press the unlocking button when installing the unlocking button; a locking block, horizontally arranged on one side of the guiding block, when the head part slides in the activity space, the locking block is parallel to the unlocking button; locking pieces are formed on both sides of the unlocking button, in an inverted L shape, and a convex block extending to one side is formed at the top thereof, the extending direction of the convex block is opposite to the direction of the locking block, and the locking pieces are used to cooperate with the locking block to limit and fix the head part.

[0007] In some embodiments, a guiding inclined surface is formed at the top of the locking piece, and a right angle is formed between the bottom of the convex block and the locking piece.

[0008] In some embodiments, the locking part further includes a reinforcing rib for enhancing the structural strength of the locking part.

[0009] In some embodiments, the unlocking button is fixed to the machine head through a spring, and a limiting lug is formed on the button.

[0010] In some embodiments, a guiding groove is formed inside the housing, guiding rails are arranged on both sides of the machine head, and the machine head realizes sliding through the cooperation of the guiding rails and the guiding groove.

[0011] In some embodiments, the unlocking button slides right below the opening groove.

[0012] The beneficial effects of the present application are as follows: The machine head cooperates with the locking part through the unlocking button thereon. When the machine head is slidably installed on the nail gun body, since the locking part is guided by the inclined surface of the guiding block, the unlocking button is driven to be pressed. After being installed in place, the unlocking button resets under the action of the spring. At this time, the locking part is blocked by the locking block, so that the machine head can only slide on the nail gun body and will not detach. The machine head can be quickly disassembled after pressing the unlocking button. Among them, the machine head needs to slide a certain distance into the nail gun body to make the locking part disengage from the locking block before the unlocking button can be pressed, which has the effect of preventing accidental touch. The quick-disassembly structure of the present application can realize the quick disassembly and assembly of the machine head, facilitating daily maintenance, replacement and cleaning.
