[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figs. 1-3 The embodiments of this utility model include:

[0024] A detachable nailer, mainly used for nailing open nails 12 or pull-out screws, includes the following structure: connecting rod 1, limiting slot 2, mounting cavity 3, retaining spring 4, limiting connecting groove 5, fixing screw 6, fixing screw hole 7, handle 8, connecting slot 9, fixing connector 10, and fixing connecting hole 11.

[0025] The mounting cavity is located inside the connecting rod, and its opening is located on the front end face of the connecting rod for nail mounting. The limiting slot surrounds the outer periphery of the front end of the mounting cavity and communicates with the mounting cavity. The limiting slot cooperates with the card seat on the nail to not only position and limit the nail, but also to insert with the card seat to help improve the stability of the installation.

[0026] In a further preferred embodiment, the limiting slot and the mounting cavity are concentric structures.

[0027] A limiting connection groove is axially provided on the outer peripheral wall of the connecting rod, and a fixing screw hole is radially provided on the connecting rod. The front end of the limiting connection groove is connected to the mounting cavity through the through hole 51, and its rear end is connected to the upper part of the fixing screw hole. The snap ring is provided in the limiting connection groove, and the snap hook part 41 of its head passes through the through hole and extends into the mounting cavity to fix the nail by snapping with the groove on the nail. The lower end of the fixing screw passes through the fixing ring at the tail of the snap ring and is threadedly connected to the fixing screw hole to fix the snap ring on the connecting rod.

[0028] A further preferred embodiment has a fixing screw hole that is radially through-hole on the connecting rod.

[0029] The handle has a connecting slot, which allows the rear end of the connecting rod to be inserted into the connecting slot. A fixing connection hole is provided on the handle and communicates with the connecting slot. The fixing connector passes through the fixing connection hole and the hole at the rear end of the connecting rod to fix the connecting rod to the handle.

[0030] A further preferred embodiment has a fixed connection hole that is radially through the handle.

[0031] More preferably, the fixing fasteners can be fasteners such as rivets and screws.

[0032] A further preferred option is that the handle is made of bakelite.

[0033] When installing the nail, first select a suitable connecting rod and insert it into the handle, then lock it with the fixing connector. Next, lock the snap ring onto the connecting rod, and then insert the nail into the mounting cavity. The tail of the nail will push the snap ring's hook outwards. When fully inserted, the hook aligns with the groove on the nail and, under its own restoring force, returns to its original position, causing the hook to engage with the groove, thus securing the nail. To remove the nail, loosen the fixing screw to disengage the snap ring's hook from the groove on the nail.

[0034] The advantages of this detachable nailer are: it can not only improve the accuracy and stability of the connection between the nail and the nailer, thereby improving the quality and efficiency of nailing, but also has a simple structure, is easy to disassemble and use, is easy to clean and disinfect, and can be used to install different types of screws, with strong adaptability.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
