Then, under the elastic force of the third elastic element 209, the slot-shaped housing 207, the inner cover 208 and the nail box are reset to the state shown in fig. 3, the nail striking member 201 is withdrawn from the nail outlet 303, and the rows of nails in the nail box are pushed forward by the nail pushing member 302 by a distance of one nail to repair.

The magazine 300 is used to store nails 400 and to push the nails forward toward the outlets 303 for hammering, the driver 201 blows the nails corresponding to the outlets, and the struck nails are separated from the rows of nails as shown in fig. 5 and driven into the corresponding locations. In this embodiment, the staple cartridge 300 includes a first slot-like cartridge 309, a second slot-like cartridge 310, a staple cartridge head 311, a staple pusher 302, a guide rod 308, and a first resilient element 301. The width of the second channel pocket 310 is slightly smaller than the width of the first channel pocket 309, and the second channel pocket 310 is centrally located within the first channel pocket 309, such that a gap 312 is maintained between the side walls of the first channel pocket 309 and the side walls of the second channel pocket 310 for storing nails, i.e., rows of nails 400 ride on the second channel pocket 310 as shown in fig. 5, and the gap also provides a space for the forward and backward movement of the staple pusher 302 and guides the forward and backward movement of the staple pusher. As shown in fig. 3, the cartridge head 311 is assembled to the first slot-like cartridge 309, thereby forming the staple outlet 303 corresponding to the staple between the front ends of the first slot-like cartridge 309, the second slot-like cartridge 310 and the cartridge head 311.

The nail pushing member pushes the nail forward under the elastic force of the first elastic member.

In order to replenish the nail in the magazine, after the nail in the magazine is struck as shown in fig. 3, the nail needs to be replenished into the magazine. Thus, the magazine 300 is rotatably disposed relative to the housing 200 to be capable of being in a closed condition relative to the housing, such as shown in fig. 3, for placing the nail in the hammer able condition, and an open condition, such as shown in fig. 7, for loading a nail into the magazine. Specifically, the rear end of the first slot-like pocket 309 of the magazine is assembled to the slot-like housing 207 together with the inner cover by the pin shaft 211.

In fig. 3 and 7, a pulling member 305 is shown connected between the staple pusher 302 and the housing 200. The pulling member 305 is a flexible member, and the pulling member 305 is relaxed when the magazine and the housing are in the closed position shown in fig. 3. The pulling member pulls the ejector back when the magazine is in the separated condition from the housing as shown in fig. 7, thereby freeing up space in front of the ejector 302 for loading nails. In fig. 7, the drawing member is indicated by a two-dot chain line, and the intention is that the push member 302 is not pulled back by the drawing member when the magazine and the housing are in the separated state shown in fig. 7, but is held at the forefront end of the magazine shown in fig. 7 by the urging force of the first elastic member 301, and when nails are to be loaded, it is necessary to push the push member 302 rearward with a finger to hold the position of loading the nails in front of the push member, assuming that the drawing member is absent. In contrast, without the pulling member, the nail loading operation is troublesome. Specifically, as shown in fig. 8-9, the nail pushing member 302 is provided with a second connecting hole 306, the inner cover 208 of the outer casing 200 is provided with a first connecting hole 206, the pulling member 305 is a flat sheet, two ends of the pulling member are provided with connecting notches 307, and the connecting notches at two ends of the pulling member are clamped in the corresponding connecting holes to realize connection.

As described above, in the present embodiment, the magazine and the housing are in the closed state shown in fig. 3 by the locking structure, so as to avoid accidental separation of the two. The locking structure is arranged between the shell and the nail box and used for locking the nail box and the shell in a folding state.

As shown in fig. 1-3 and 6-7, the locking structure includes a finger control portion 202, a second elastic element 205, and a first locking portion 203 and a second locking portion 304 separately provided on the housing and the magazine.

In this embodiment, the finger control 202 is located on the top surface of the housing adjacent the handle 100 so that when the handle is held by a hand, the finger of the hand can manipulate the finger control to unlock the locking mechanism. The first locking portion 203 is two hooks which are symmetrically oriented toward the rear. The second locking portion 304 is a flange provided on both sides of the first slot-like pocket 309. Further, the top surface of the groove-shaped body of the housing has a guide hole 204, and the first locking portion 203 is located in the body and is connected to the finger control portion 202 via the guide hole 204, so that the first locking portion and the finger control portion are assembled to the groove-shaped body and can move forward and backward. Further, as shown in fig. 6, two bilaterally symmetrical hooks reside on both sides of the magazine and correspond to one flange, respectively. The second elastic element 205 is a spiral tension spring, and two ends of the second elastic element are respectively connected to the slot-shaped housing 207 and the first locking portion 203, so that when the nail magazine and the housing are in a closed state, the locking structure hooks the flange by the elastic force of the second elastic element 205 to make the hook located at the lower side of the flange, and the locking structure is in a locking state. The finger of the hand holding the handle is used to push the finger control part 202 forward, so that the hook can be separated from the flange by overcoming the elastic force of the second elastic element 205, and the locking structure is unlocked. Then, the nail gun is swung or the nail box is stirred by fingers to separate the nail box 300 from the shell 200, so that nails can be installed, and the operation is convenient and efficient. After the nails are loaded into the nail cartridge, the nail cartridge 300 and the casing 200 can be closed by reversely swinging or pulling the nail cartridge by fingers, and the elastic force of the second elastic element 205 causes the locking structure to lock the nail cartridge and the casing in the closed state.

As a modification of the present embodiment: when the nail box and the shell are in a closed state, the locking structure enables the hook to move forward to be positioned at the lower side of the flange to hook the flange by means of the elasticity of the second elastic element, and the locking structure is in a locking state. When the nail box is to be unlocked, the finger control part is moved backwards by the fingers of the hand holding the handle, the elastic force of the second elastic element is overcome, the hook and the flange can be separated, the locking structure is unlocked, the nail box is separated from the shell in a homeopathic manner, and nails can be installed, so that the operation is convenient and efficient.

It is foreseeable that the first locking part and the second locking part are replaced, namely, the flange is used as the first locking part, and the flange is hooked on two sides of the first groove-shaped box body, so that the locking can be realized by pushing the finger control part forwards or moving the finger control part backwards.

In addition, when the nail box and the shell are in the closed state, in order to keep the locking structure in the locking state, the second elastic element can be cancelled, so that the control piece is positioned in the locking state of the locking structure by the positioning structure, for example, the positioning protrusion and the positioning pit are separately arranged on the finger control part and the groove-shaped shell, and the positioning protrusion is positioned in the positioning pit to realize positioning. At this time, the force for moving the manipulation member is derived from the fingers of the hand holding the handle.
