Description

Technical Field

[0001] This invention relates to the field of nail gun technology, and in particular to a nail gun structure, a nail gun, and a method of using the same. Background Technology

[0002] A nail gun is a tool that uses high-pressure gas generated by firing to drive a piston rod at high speed, which in turn strikes a nail, thus driving the nail into a substrate. It is commonly used in construction, decoration, and mechanical installation. Existing nail guns typically include a firing mechanism, a firing mechanism, and a reset mechanism. The firing mechanism controls the firing pin to complete the firing action; the firing mechanism uses the high-pressure gas generated by firing to drive the piston rod; and the reset mechanism restores the relevant moving parts to the position required for the next firing after one nail-driving operation.

[0003] In existing nail guns, after each firing, the firing pin in the firing mechanism shifts under the impact of the firing action, and the piston rod in the firing mechanism moves rapidly under high-pressure gas. Therefore, before the next nail firing operation, both the firing pin and the firing mechanism need to be reset. In existing structures, the locking, releasing, and resetting of the firing pin are usually achieved by the cooperation of multiple components. After each firing, the firing mechanism and the firing pin need to re-establish their engagement, and then the reset mechanism returns the firing pin to its firing position.

[0004] However, in the aforementioned reset process, the re-coordination between the firing element and the firing pin, as well as the reset of the firing pin, typically require multiple sequential motions. There is a lack of effective linkage between the initial reset after firing and the subsequent overall reset. When the firing element has not yet re-established a reliable engagement with the firing pin, the subsequent reset action is difficult to effectively transmit to the firing pin, which can easily lead to the firing pin failing to return to its predetermined position synchronously with the reset structure, thus affecting the firing structure's return to the next firing state. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a nail gun structure, a nail gun, and a method of using the same, to solve the problem that in existing nail guns, the coordination relationship between the firing structure, the launching structure, and the reset structure is relatively complex, and after completing a nail gun operation, the firing pin body and the launching part need to be returned to the predetermined position respectively, which results in inconvenient reset operation and difficulty in the coordinated restoration of each structure to the next firing state.

[0006] In a first aspect, embodiments of the present invention provide a nail-shooting structure, comprising: The body includes a joint and a guide, both of which have internal cavities and are connected by a firing channel; The firing unit is disposed within the guide portion and includes a reset block, a firing element, a firing pin body, and a firing spring for driving the firing pin body to fire. The firing element is movable relative to the reset block, and a locking block is provided inside the firing element. The firing pin body is provided with a locking groove that cooperates with the locking block. The triggering unit includes a trigger and a firing lever, the firing lever cooperating with the firing element to drive the firing element to move and disengage the locking block from the locking slot; A push rod is disposed at the joint, and the push rod is capable of pushing the reset block to move; The locking block engages with the locking slot to restrict the movement of the firing pin body along the firing direction; The trigger drives the firing lever to rotate, causing the firing lever to drive the firing element to move along the guide groove of the reset block, so that the locking block disengages from the locking groove and releases the firing pin body; The reset block can drive the firing element to move along the reset slope of the firing pin body, so that the locking block can re-engage with the locking slot; When the push rod moves the reset block, the firing pin body is reset through the locking relationship between the firing element and the firing pin body.

[0007] Secondly, a nail gun is provided, comprising: A first magazine and a second magazine, the bottom of the first magazine and the second magazine forming a handle, the handle having a magazine compartment for accommodating a magazine carrying a bullet; The frame is fixedly installed inside the first housing; A firing tube is disposed within the frame. A nail tube sleeve is provided outside the firing tube. A nail tube for receiving a nail is provided at the front end of the firing tube inside the nail tube sleeve. A protective sleeve is provided outside the nail tube sleeve. A piston rod is provided inside the firing tube. A connecting tube is provided at the rear end of the firing tube. The connecting tube connects the firing channel of the nail structure with the inside of the firing tube. A directional locking block is disposed outside the frame, and the directional locking block cooperates with the piston rod to restrict the movement of the piston rod relative to the launching tube; A nailing structure is disposed within the internal space formed by the first housing and the second housing, wherein the nailing structure is the nailing structure described in the first aspect; The sheath, nail tube, nail tube sleeve, and launching tube are movable relative to the frame, and the directional locking block can cooperate with the piston rod to move the piston rod relative to the launching tube and complete the reset. When the nail gun structure fires the projectile, the gas generated can enter the firing tube through the connecting tube and act on the piston rod to drive the piston rod to move along the firing tube and fire the nail out of the nail tube to complete the nail firing operation.

[0008] Thirdly, a method for using a nail gun is provided, including: The sheath, nail tube, nail tube sleeve, and firing tube are moved relative to the frame in the first direction. The movement of the piston rod is restricted by the directional locking block, so that the piston rod moves relative to the firing tube and completes the reset. The sheath, nail tube, nail tube sleeve, and firing tube are moved relative to the frame in a second direction opposite to the first direction. The firing tube pushes the push rod, which in turn pushes the reset block and puts the nail firing structure into the firing state. The trigger is driven, causing the firing lever to move the firing element and release the engagement between the firing element and the firing pin body. The firing pin body then fires the projectile under the action of the firing spring. The gas generated by the projectile enters the firing tube through the connecting tube and acts on the piston rod, driving the piston rod to move and complete the nail firing operation through the nail tube.

[0009] The nail gun structure, nail gun, and method of use provided by this invention have the following beneficial effects: In this invention, by setting a locking block and a locking groove that cooperate between the firing element and the firing pin body, after firing, the reset block drives the firing element to move along the reset slope of the firing pin body, so that the locking block re-engages with the locking groove, thereby restoring the force transmission relationship between the firing element and the firing pin body; then, the reset block is pushed by the push rod, and the reset force is transmitted to the firing pin body by utilizing the re-established locking relationship, so that the firing pin body resets synchronously with the firing element. This realizes the staged linkage reset of the firing structure, reduces the unreliable coordination problem caused by the separate reset of each component, and enables the firing pin body to stably return to the position required for the next firing, thereby improving the reliability of the firing structure reset during continuous firing of the nail gun.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, the element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Where there is no conflict, embodiments of the present invention and the various features thereof can be combined with each other, all of which are within the scope of protection of the present invention.

[0013] Example 1 Please see Figure 2 ,as well as Figures 5-12 This invention provides a nailing structure, comprising: Please see Figure 5 and Figure 6 The body 100 includes a joint and a guide 120, both of which have an inner cavity and are connected by a firing channel 121.

[0014] Please see Figure 2 , Figure 7 and Figure 8 The firing unit is disposed within the guide portion 120 and includes a reset block 210, a firing element 220, a firing pin body 230, and a firing spring 237 for driving the firing pin body 230 to fire. The firing element 220 is movable relative to the reset block 210. The firing element 220 is provided with a locking block 223, and the firing pin body 230 is provided with a locking groove 232 that cooperates with the locking block 223.

[0015] Please see Figure 2 and Figure 11The triggering unit includes a trigger 310 and a firing lever 320. The firing lever 320 cooperates with the firing element 220 to drive the firing element 220 to move and cause the locking block 223 to disengage from the locking groove 232. A push rod 400 is disposed at the joint, and the push rod 400 is capable of pushing the reset block 210 to move; The locking block 223 engages with the locking groove 232 to restrict the movement of the firing pin body 230 along the firing direction; The trigger 310 drives the firing lever 320 to rotate, causing the firing lever 320 to drive the firing element 220 to move along the guide groove 211 of the reset block 210, so that the locking block 223 disengages from the locking groove 232 and releases the firing pin body 230. The reset block 210 can drive the firing element 220 to move along the reset inclined surface 233 of the firing pin body 230, so that the locking block 223 can re-engage with the locking groove 232; When the push rod 400 pushes the reset block 210 to move, the firing pin body 230 is reset through the snap-fit ​​relationship between the firing element 220 and the firing pin body 230.

[0016] Specifically, the body 100, serving as the mounting and load-bearing connection transition of the nail gun structure, includes a joint and a guide 120. Both the joint and the guide 120 have internal cavities. The joint and the guide 120 are connected via a firing channel 121, allowing the firing action generated during firing to be transmitted along the firing channel 121 to the firing position of the nail gun structure. The joint is mainly used to cooperate with relevant reset components in the nail gun, while the guide 120 is used to accommodate and guide the movement of the firing unit.

[0017] Please see Figure 2 and Figure 11The firing unit is disposed within the guide portion 120 and includes a reset block 210, a firing element 220, a firing pin body 230, and a firing spring 237. The reset block 210 serves as a force-transmitting component during the firing unit's reset process and can move within the guide portion 120 in a predetermined direction. The reset block 210 has a guide groove 211, within which the firing element 220 is disposed, allowing it to move relative to the reset block 210 under its guidance. The firing element 220 has a locking block 223, and the firing pin body 230 has a locking groove 232 that engages with the locking block 223. In the firing preparation state, the locking block 223 and the locking groove 232 engage with each other, thereby establishing a mutual limiting relationship between the firing element 220 and the firing pin body 230. Because the firing element 220 is restricted by the reset block 210 and related structures, the locking block 223 can be held in the locking groove 232, thereby restricting the movement of the firing pin body 230 in the firing direction, keeping the firing pin body 230 in the energy storage position before firing, and the firing spring 237 is in a ready state that can drive the firing pin body 230 to fire.

[0018] The triggering unit includes a trigger 310 and a firing lever 320, which cooperates with the firing element 220. When nail shooting is required, a force is applied to the trigger 310 in its triggering direction. The trigger 310 drives the firing lever 320 to rotate. The rotated firing lever 320 applies a driving force to the firing element 220, causing the firing element 220 to move along the guide groove 211 of the reset block 210. During the movement of the firing element 220, the internal locking block 223 is displaced relative to the firing pin body 230 along with the firing element 220, and gradually disengages from the locking groove 232 on the firing pin body 230. When the locking block 223 is completely disengaged from the locking slot 232, the locking relationship between the firing element 220 and the firing pin body 230 is released. At this time, the firing pin body 230 is no longer limited by the locking block 223 along the firing direction. The elastic potential energy stored in the firing spring 237 is released and drives the firing pin body 230 to move rapidly along the firing direction, so that the firing pin body 230 completes the firing action through the firing channel 121.

[0019] After a firing is completed, the firing unit needs to be restored to the state required for the next firing. In this embodiment, the reset process of the firing unit includes two stages: re-establishing the engagement between the firing element 220 and the firing pin body 230, and further resetting the firing pin body 230.

[0020] After firing, the reset block 210 moves along the reset direction, causing the firing element 220, which is located in its guide groove 211, to move synchronously. Since the firing pin body 230 has a reset ramp 233, the firing element 220 can contact the reset ramp 233 as it moves with the reset block 210, and move along the surface of the reset ramp 233, causing a relative displacement between the firing element 220 and the firing pin body 230 for re-engaging. As the firing element 220 continues to move, the locking block 223 within the firing element 220 moves to a position corresponding to the locking groove 232 on the firing pin body 230, and re-enters the locking groove 232, thereby re-establishing the engagement relationship between the firing element 220 and the firing pin body 230.

[0021] After the aforementioned re-engaging is completed, the firing element 220 and the firing pin body 230 re-establish a connection capable of transmitting the reset force. At this time, the push rod 400 provided at the joint can apply a pushing action to the reset block 210, causing the reset block 210 to move along the predetermined reset direction. Since the firing element 220 has been re-engaged with the firing pin body 230 through the locking block 223 and the locking groove 232, the movement of the reset block 210 can drive the firing element 220 to move synchronously, and the firing element 220 transmits the reset force to the firing pin body 230 through the locking block 223 and the locking groove 232, thereby causing the firing pin body 230 to reset in the direction opposite to the firing direction, so that the firing pin body 230 returns to the position required for the next firing.

[0022] Therefore, in this embodiment, the reset after firing is not directly applied to the firing pin body 230 by the push rod 400. Instead, the reset block 210 first drives the firing element 220 to move along the reset slope 233 of the firing pin body 230, so that the locking block 223 of the firing element 220 re-enters the locking groove 232 of the firing pin body 230. After the firing element 220 and the firing pin body 230 re-establish the locking relationship, the push rod 400 pushes the reset block 210, and the firing pin body 230 is driven to complete the subsequent reset through the force transmission path of "reset block 210 - firing element 220 - locking block 223 and locking groove 232 - firing pin body 230".

[0023] In this embodiment, through the above-described phased reset process, the firing element 220 can both reposition the firing pin body 230 after firing and transmit the movement of the reset block 210 to the firing pin body 230 after re-engaging, thereby restoring the firing pin body 230 to the position required for the next firing.

[0024] Further, please see Figure 5 and Figure 6The joint includes a first joint block 111 and a second joint block 112 spaced apart, forming a magazine channel 114 between the first joint block 111 and the second joint block 112 to provide space for the magazine to be accommodated and moved. After the nail gun structure completes one firing, the magazine can move upward in a predetermined direction and be guided and avoid obstacles through the magazine channel 114, thereby avoiding interference between the magazine and the joint during movement and ensuring that the magazine can move smoothly to the next firing position.

[0025] Furthermore, the first connecting block 111 and the second connecting block 112 are respectively provided with arc-shaped connecting surfaces 113 on the side facing the magazine channel 114. The connecting surfaces 113 are used to cooperate with the connecting tube 621 of the nail gun. During the process of the connecting tube 621 moving towards the body 100 and engaging with the connecting part, the connecting tube 621 first contacts the connecting surface 113, and gradually adjusts its position under the guidance of the arc-shaped structure, so that the connecting tube 621 enters the connecting part in a predetermined direction, thereby guiding and positioning the connecting tube 621. As the connecting tube 621 continues to move, its position is gradually adjusted to correspond to the firing channel 121 in the body 100, so that the connecting tube 621 and the firing channel 121 remain in a connected state, so as to ensure that the relevant gas can be transmitted according to the predetermined path during firing, and that the nail gun structure can complete the firing operation normally. The arc-shaped connecting surface 113 can also reduce the jamming caused by positional deviation when the connecting tube 621 engages with the connecting part.

[0026] Furthermore, the second connecting block 112 is provided with a guide channel for accommodating the push rod 400. The push rod 400 is disposed within the guide channel and can move along the guide channel. When the nail gun performs a reset operation, the push rod 400 is pushed by an external moving part and moves along the guide channel toward the reset block 210. This restricts the direction of movement of the push rod 400 by the guide channel, thereby enabling the push rod 400 to stably apply a pushing action to the reset block 210. This prevents significant deviation of the push rod 400 during the process of pushing the reset block 210, maintains a stable engagement between the push rod 400 and the reset block 210, and ensures that the reset block 210 can move in a predetermined direction, thereby completing the reset of the firing unit.

[0027] Further, please see Figure 2 and Figure 9The reset block 210 has a guide groove 211 inside, and the firing element 220 is disposed in the guide groove 211, so that the firing element 220 can move along the guide groove 211 to limit the movement direction of the firing element 220. A firing reset spring 212 is provided between the firing element 220 and the guide groove 211. The firing reset spring 212 can elastically deform during the movement of the firing element 220, and after firing, it applies a reset force to the firing element 220 toward its initial position, so that after the triggering effect is released, the firing element 220 can move in the opposite direction along the guide groove 211 under the elastic restoring force of the firing reset spring 212, and gradually return to the preset firing position.

[0028] Specifically, during firing, the trigger 310 drives the firing element 220 to move along the guide groove 211 via the firing lever 320, causing the locking block 223 of the firing element 220 to disengage from the locking groove 232 of the firing pin body 230. Simultaneously, the firing return spring 212 is compressed or stretched to store elastic potential energy. After the firing pin body 230 completes firing, the firing return spring 212 releases the stored elastic potential energy and pushes the firing element 220 back to its initial position, returning it to the position corresponding to the next firing. During the reset process, the firing element 220 can cooperate with the reset ramp 233 of the firing pin body 230, causing the locking block 223 of the firing element 220 to re-engage with the locking groove 232 of the firing pin body 230, thereby restoring the limiting relationship to the firing pin body 230. Therefore, the firing return spring 212 can not only restore the firing element 220 to the preset position after firing once, but also provide a reset driving force for the firing element 220 and the firing pin body 230 to re-establish the engagement relationship, so that the firing structure can return to the ready state required for the next firing.

[0029] Further, please see Figure 7 and Figure 8 The firing element 220 is arranged in a ring shape, allowing it to be fitted onto the outside of the firing pin body 230 and move in a predetermined direction within the guide groove 211 of the reset block 210. A trigger block 221 is provided at the bottom of the firing element 220, which cooperates with the firing lever 320. When firing is required, the trigger 310 drives the firing lever 320 to rotate, causing the firing lever 320 to contact the trigger block 221 and apply a pushing force to it, thus moving the firing element 220 along the guide groove 211. As the firing element 220 moves, the locking block 223 on the firing element 220 gradually disengages from the locking groove 232 of the firing pin body 230, thereby releasing the restriction on the firing pin body 230 and allowing the firing spring 237 to drive the firing pin body 230 to move in the firing direction and complete the firing action. After firing, the firing element 220 moves along the guide groove 211 in the reset direction under the action of the firing reset spring 212, providing a motion basis for re-establishing the engagement relationship with the firing pin body 230.

[0030] Furthermore, the top of the firing pin body 230 is provided with a reset groove 231, and the end of the reset groove 231 near the locking groove 232 is provided with a reset inclined surface 233. The reset groove 231 is used to provide a matching space for the reset movement of the firing element 220, and the reset inclined surface 233 is used to guide the firing element 220 during the reset process. Specifically, after firing, the reset block 210 drives the firing element 220 to move in the reset direction, and the firing element 220 gradually enters the reset groove 231 at the top of the firing pin body 230 and contacts the reset inclined surface 233. As the firing element 220 continues to move, the firing element 220 moves along the reset inclined surface 233, so that the firing element 220 generates a predetermined relative displacement with respect to the firing pin body 230, thereby causing the locking block 223 on the firing element 220 to gradually approach the locking groove 232. When the firing element 220 moves to the predetermined position, the locking block 223 re-enters the locking groove 232 and forms a locking engagement with the locking groove 232, so that the firing element 220 and the firing pin body 230 re-establish a connection relationship.

[0031] Specifically, through the above-described configuration, the firing element 220 can move under the action of the firing lever 320 during firing to release the engagement between the locking block 223 and the locking groove 232. After firing, it can re-enter the locking position corresponding to the firing pin body 230 using the guidance of the reset groove 231 and the reset ramp 233, allowing the locking block 223 to re-engage with the locking groove 232. Therefore, the reset ramp 233 actually constitutes a guide structure in the process of the firing element 220 re-establishing the locking relationship, enabling the reset movement of the firing element 220 to be transformed into relative position adjustment between the locking block 223 and the locking groove 232, providing a reliable locking foundation for the subsequent overall reset of the firing pin body 230 via the reset block 210 and the push rod 400.

[0032] Further, please see Figure 2 , Figure 7 and Figure 8 The firing pin body 230 has a firing pin head 234 at one end and a fixing nut 236 at the other end. The firing pin head 234 is used to move towards the firing channel 121 during firing and act on the part to be fired to complete the firing action. The fixing nut 236 is used to limit the relevant components at the end of the firing pin body 230. A return spring 213 is provided between the firing pin body 230 and the return block 210. The return spring 213 can generate elastic deformation when the firing pin body 230 moves during firing and apply an elastic force towards the return direction to the firing pin body 230 after firing, so that the firing pin body 230 tends to return to its initial position.

[0033] The firing pin body 230 is also provided with a safety washer ring 235, which is sleeved on the firing pin body 230 and can move with the firing pin body 230. A buffer spring 238 is provided between the safety washer ring 235 and the fixing nut 236, and a firing spring 237 is provided between the safety washer ring 235 and the tail cap 240. Thus, the buffer spring 238 is located inside the firing spring 237, so that the safety washer ring 235 can act as a working component between the firing spring 237 and the firing pin body 230, and at the same time, it forms an elastic fit with the fixing nut 236 through the buffer spring 238.

[0034] Specifically, before firing, the firing element 220 engages with the locking groove 232 of the firing pin body 230 via the locking block 223, thus limiting the firing pin body 230, and the firing spring 237 is in a state of storing elastic potential energy. When the trigger 310 drives the firing lever 320 to move the firing element 220 and release the locking block 223 from the locking groove 232, the firing pin body 230 is released from its limit, the firing spring 237 releases its elastic potential energy and acts on the safety washer ring 235, causing the safety washer ring 235 to drive the firing pin body 230 to move rapidly in the firing direction, thereby enabling the firing pin head 234 to complete the firing action. During the rapid movement of the firing pin body 230, the buffer spring 238 can generate elastic deformation between the safety washer ring 235 and the fixing nut 236 to buffer the movement of the firing pin body 230 and reduce the rigid impact generated when the firing pin body 230 moves to the end position.

[0035] After firing, the return spring 213 applies a reset force to the firing pin body 230, causing it to tend to move back to its initial position. Simultaneously, the firing element 220 is reset by the firing return spring 212 and re-engages with the firing pin body 230 through the engagement of the reset groove 231 and the reset ramp 233. Once the firing element 220 and firing pin body 230 are re-engaged, the push rod 400 pushes the reset block 210 to move. The reset block 210 further moves the firing element 220, and the reset force is transmitted to the firing pin body 230 through the engagement between the locking block 223 and the locking groove 232, thus restoring the firing pin body 230 to the position required for the next firing.

[0036] Further, please see Figure 2 and Figure 12The bracket 500 includes a first support plate 510 and a second support plate 520 arranged in an "L" shape. The first support plate 510 and the second support plate 520 are connected to form a support structure for mounting and supporting the trigger unit. The first support plate 510 is provided with a first side plate 511 and a second side plate 512 spaced apart. An installation space for accommodating the firing lever 320 is formed between the first side plate 511 and the second side plate 512, and a fixing pin 513 is provided between the first side plate 511 and the second side plate 512. The firing lever 320 is provided with a pin groove 323, and the pin groove 323 is rotatably engaged with the fixing pin 513, so that the firing lever 320 can rotate with the fixing pin 513 as the fulcrum, thereby transmitting the driving force applied by the trigger 310 to the firing element 220.

[0037] The firing lever 320 includes a trigger rod 321 and a trigger bend 322. The trigger rod 321 cooperates with the trigger 310, and the trigger bend 322 cooperates with the firing element 220.

[0038] Specifically, during the firing operation, the operator applies force to the trigger 310, which pushes the trigger lever 321, causing the firing lever 320 to rotate around the fixed pin 513. During the rotation of the firing lever 320, the trigger bend 322 moves synchronously with the firing lever 320 and cooperates with the firing element 220 to apply a driving force to the firing element 220 along the direction of the guide groove 211 of the reset block 210, causing the firing element 220 to move. This causes the locking block 223 on the firing element 220 to disengage from the locking groove 232 of the firing pin body 230, releasing the limitation on the firing pin body 230, so that the firing pin body 230 can complete the firing under the action of the firing spring 237.

[0039] A lever return spring 324 is provided between the trigger rod 321 and the trigger bend 322. The lever return spring 324 is used to generate elastic deformation during the rotation of the firing lever 320, and to apply a reset force to the firing lever 320 after the trigger 310 is released, so that the firing lever 320 can return to the initial position, thereby restoring the trigger rod 321 and the trigger bend 322 to the position required for the next firing.

[0040] A first trigger spring 325 is also provided between the trigger rod 321 and the bracket 500. The first trigger spring 325 can undergo elastic deformation during the operation of the trigger 310, and release elastic potential energy after the trigger 310 is released, applying a reset force to the trigger rod 321, so that the firing lever 320 returns to its initial state.

[0041] Further, please see Figure 7 and Figure 8The trigger block 221 has recessed inclined surfaces 222 on both sides, forming a mating area with a relatively concave center. The recessed inclined surfaces 222 are used to cooperate with the firing lever 320. When the trigger 310 drives the firing lever 320 to rotate, the firing lever 320 can contact the side of the trigger block 221 and slide relative to the recessed inclined surfaces 222, thereby converting the rotational motion of the firing lever 320 into the movement of the firing element 220 along the guide groove 211 of the reset block 210.

[0042] Specifically, during firing, the firing lever 320 rotates with the trigger 310 and contacts the recessed inclined surface 222 on one side of the trigger block 221. As the firing lever 320 continues to rotate, its position changes along the recessed inclined surface 222, causing the firing element 220 to be pushed along the guide groove 211 and move, thereby causing the locking block 223 to disengage from the locking groove 232 of the firing pin body 230. After firing, the firing element 220 moves back to its initial position under the action of the firing return spring 212. The recessed inclined surface 222 provides corresponding mating space for the firing lever 320, allowing the firing lever 320 to return to the position corresponding to the trigger block 221 as the firing element 220 resets.

[0043] Further, please see Figure 11 The trigger 310 includes a pulling body 311 and a trigger plate 312. The trigger plate 312 cooperates with the trigger rod 321 so that when the operator applies a pulling action to the pulling body 311, the pulling body 311 can drive the trigger plate 312 to generate a corresponding movement, and the trigger plate 312 applies a force to the trigger rod 321, causing the trigger rod 321 to drive the firing lever 320 to rotate around its rotation fulcrum. This causes the trigger bend 322 of the firing lever 320 to act on the trigger block 221 of the firing element 220, driving the firing element 220 to move along the guide groove 211 of the reset block 210, thereby releasing the jamming relationship between the firing element 220 and the firing pin body 230 and completing the firing.

[0044] A second trigger spring 313 and a third trigger spring 314 are provided between the trigger plate 312 and the bracket 500. The second trigger spring 313 and the third trigger spring 314 are elastically engaged with the trigger plate 312. When the trigger body 311 is engaged, the trigger plate 312 moves with the trigger body 311, causing the second trigger spring 313 and the third trigger spring 314 to undergo elastic deformation and store elastic potential energy. When the engagement of the trigger body 311 is released, the second trigger spring 313 and the third trigger spring 314 release their elastic potential energy and apply a reset force to the trigger plate 312, causing the trigger plate 312 to return to its initial position and drive the trigger rod 321, which is engaged with it, to return to its initial position. This allows the firing lever 320 and the firing element 220 to return to the trigger position required for the next firing.

[0045] In this embodiment, by setting a second trigger spring 313 and a third trigger spring 314, the pulling and releasing process of the trigger 310 has a corresponding elastic reset function. At the same time, in conjunction with the lever return spring 324 of the aforementioned firing lever 320 and the firing reset spring 212 of the firing element 220, the trigger 310, the firing lever 320 and the firing element 220 can be returned to the predetermined position in sequence after completing one firing, so as to ensure that when the trigger 310 is pulled again, the trigger plate 312 can reliably drive the trigger rod 321 and the firing lever 320 to complete the firing action.

[0046] Example 2 Please see Figures 1-12 This invention provides a nail gun.

[0047] Please see details. Figure 1 and Figure 2 The nail gun includes: A first magazine 600 and a second magazine 700, the bottom of the first magazine 600 and the second magazine 700 forming a grip 800, the grip 800 having a magazine compartment 810 for accommodating a magazine carrying a bullet. Please see details. Figure 3 The frame 610 is fixedly disposed inside the first housing 600; A firing tube 620 is disposed within the frame 610. A nail tube sleeve 670 is provided outside the firing tube 620. A nail tube 630 for receiving a nail is provided at the front end of the firing tube 620 within the nail tube sleeve 670. A protective sleeve 640 is provided outside the nail tube sleeve 670. A piston rod 651 is provided inside the firing tube 620. A connecting tube 621 is provided at the rear end of the firing tube 620. The connecting tube 621 connects the firing channel 121 of the nail structure and the interior of the firing tube 620. A directional locking block 660 is disposed outside the frame 610. The directional locking block 660 cooperates with the piston rod 651 to restrict the movement of the piston rod 651 relative to the launching tube 620. A nail-shooting structure is disposed within the internal space formed by the first housing 600 and the second housing 700, wherein the nail-shooting structure is the nail-shooting structure described in any one of Embodiment 1; The sheath 640, nail tube 630, nail tube sleeve 670 and launching tube 620 are movable relative to the frame 610, and the directional locking block 660 can cooperate with the piston rod 651 to move the piston rod 651 relative to the launching tube 620 and complete the reset. When the nail gun structure fires the projectile, the gas generated can enter the firing tube 620 through the connecting pipe 621 and act on the piston rod 651 to drive the piston rod 651 to move along the firing tube 620 and fire the nail out of the nail tube 630 to complete the nail firing operation.

[0048] Specifically, the first magazine 600 and the second magazine 700 are connected to each other, and a grip 800 for the operator to hold is formed at the bottom of both. The grip 800 has a magazine compartment 810 inside, which is used to hold a magazine carrying bullets. The magazine can be installed in the magazine compartment 810 and can move in a predetermined direction so that the bullets in the magazine are moved sequentially to the firing position corresponding to the nail structure.

[0049] The frame 610 is fixedly disposed within the first housing 600, providing a mounting and guiding base for the firing tube 620 and related moving parts. The firing tube 620 is disposed within the frame 610 and is movable relative to the frame 610. A nail tube sleeve 670 is provided outside the firing tube 620, and a nail tube 630 is provided inside the nail tube sleeve 670 at the front end of the firing tube 620. The nail tube 630 is used to accommodate the nail to be fired. A protective sleeve 640 is provided outside the nail tube sleeve 670. Thus, the protective sleeve 640, the nail tube sleeve 670, the firing tube 620, and the nail tube 630 disposed within the nail tube sleeve 670 constitute a moving assembly capable of moving as a whole relative to the frame 610. A piston rod 651 is provided inside the firing tube 620. The piston rod 651 is used to move rapidly when subjected to high-pressure gas inside the firing tube 620 and transmits this movement to the nail in the nail tube 630.

[0050] Please see Figure 4 The tail of the firing tube 620 is provided with a connecting tube 621. One end of the connecting tube 621 communicates with the interior of the firing tube 620, and the other end communicates with the firing channel 121 of the nail structure. Thus, the gas generated when the nail structure fires the projectile can enter the connecting tube 621 through the firing channel 121 and further enter the interior of the firing tube 620, thereby forming a gas transmission path from the nail structure to the firing tube 620. The nail structure is disposed within the internal space formed by the first housing 600 and the second housing 700, and adopts the aforementioned nail structure form, used to control the firing of the projectile and the firing timing.

[0051] The frame 610 is externally provided with a directional locking block 660, which cooperates with the piston rod 651 to restrict the movement of the piston rod 651 relative to the firing tube 620. Specifically, the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 can move as a whole relative to the fixed frame 610; during this overall movement, the directional locking block 660 can cooperate with the piston rod 651, restricting the movement of the piston rod 651. When the firing tube 620 moves relative to the frame 610, due to the restriction of the piston rod 651 by the directional locking block 660, a relative movement occurs between the piston rod 651 and the firing tube 620, causing the piston rod 651 to move along the inside of the firing tube 620 and return to the initial position required for nail firing.

[0052] Specifically, after the nail gun completes one nailing operation, the operator can move the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 relative to the frame 610 in a predetermined direction via the sheath 640. During the movement of the firing tube 620, the directional locking block 660 limits the piston rod 651, preventing the piston rod 651 from moving synchronously with the firing tube 620. Therefore, a relative displacement occurs between the firing tube 620 and the piston rod 651, causing the piston rod 651 to move in the reset direction along the inside of the firing tube 620. As the firing tube 620 continues to move, the piston rod 651 gradually returns to the predetermined position required for the next nailing operation, thus completing the reset of the firing part.

[0053] After the firing section is reset, the firing tube 620 can move relative to the frame 610 in the opposite direction. During this process, the firing tube 620 pushes the push rod 400 in the nail firing structure, causing the push rod 400 to exert a pushing force on the reset block 210, thereby resetting the firing unit in the nail firing structure. Since the firing element 220 and the firing pin body 230 in the nail firing structure can re-establish their engagement relationship during the reset process, when the push rod 400 pushes the reset block 210 to move, the reset block 210 can transmit the reset force to the firing pin body 230 through the engagement relationship between the firing element 220 and the firing pin body 230, so that the firing pin body 230 returns to the position required for the next firing. Thus, through the reciprocating movement of the firing tube 620 relative to the frame 610, not only can the piston rod 651 be reset, but the nail firing structure can also be reset through the cooperation between the firing tube 620 and the push rod 400, so that the nail gun returns to the ready state for the next firing.

[0054] When the nail gun is in the firing preparation state, the firing element 220 in the nail gun structure remains engaged with the firing pin body 230, the firing pin body 230 is limited, and the firing spring 237 is in an energy-storing state capable of driving the firing pin body 230 to fire. After the operator triggers the trigger 310, the firing lever 320 in the nail gun structure drives the firing element 220 to move, causing the locking block 223 on the firing element 220 to disengage from the locking groove 232 of the firing pin body 230, releasing the limitation on the firing pin body 230. At this time, the firing spring 237 releases its elastic potential energy and drives the firing pin body 230 to move rapidly along the firing direction, causing the firing pin body 230 to fire the projectile located at the firing position.

[0055] After the projectile is fired, it generates high-pressure gas. This high-pressure gas enters the firing channel 121 of the nail-shooting structure, then flows through the firing channel 121 into the connecting pipe 621, and finally into the firing tube 620. The high-pressure gas inside the firing tube 620 acts on the piston rod 651, causing it to be driven by a force along the direction of the firing tube 620 and move rapidly. After the piston rod 651 moves to the front end of the firing tube 620, it impacts the nail located in the nail tube 630, causing the nail to move outward along the nail tube 630 and be ejected from the nail tube 630, thus completing one nail-shooting operation.

[0056] After the nail is fired, the nail structure re-establishes the engagement relationship between the firing element 220 and the firing pin body 230 according to the aforementioned reset process. During the process of the push rod 400 pushing the reset block 210, the firing pin body 230 is further reset. At the same time, the firing tube 620 moves relative to the frame 610 to restore the piston rod 651 to the predetermined position. Through the above cooperation, the nail structure is responsible for generating the firing gas, the connecting tube 621 is responsible for establishing the gas transmission path between the firing channel 121 and the firing tube 620, the piston rod 651 in the firing tube 620 is responsible for converting the gas action into the mechanical impact motion of the nail, and the relative movement between the firing tube 620 and the directional locking block 660 is used to complete the reset of the piston rod 651, thereby realizing the coordinated cooperation between the firing, firing and reset processes of the nail gun.

[0057] Furthermore, one end of the piston rod 651 is provided with a plurality of spaced annular grooves 653, which are arranged sequentially at intervals along the axial direction of the piston rod 651. The directional locking block 660 can engage with one of the annular grooves 653. By providing a plurality of spaced annular grooves 653, the piston rod 651 can engage with the directional locking block 660 at different positions, thereby limiting the piston rod 651 when the launching tube 620 moves relative to the frame 610, causing relative displacement between the piston rod 651 and the launching tube 620, so as to realize the reset of the piston rod 651.

[0058] Specifically, during the nail gun's reset operation, the firing tube 620 moves relative to the frame 610, and the directional locking block 660, located outside the frame 610, can enter the annular groove 653 corresponding to the piston rod 651. Because the directional locking block 660 engages with the annular groove 653, the piston rod 651 is restricted by the directional locking block 660 and cannot move synchronously with the firing tube 620. At this time, as the firing tube 620 continues to move relative to the frame 610, the piston rod 651 can move relative to the firing tube 620 along the axial direction of the firing tube 620, thereby pushing the piston rod 651 back to the position required for the next nail firing operation. Multiple annular grooves 653 provide multiple selectable engagement positions for the directional locking block 660 and maintain a stable force relationship on the piston rod 651 during relative movement.

[0059] Furthermore, a piston ring 654 is provided in the annular groove 653 of the piston rod 651. The piston ring 654 is sleeved on the piston rod 651 and can move with the piston rod 651 within the firing tube 620. The diameter of the piston ring 654 is greater than or equal to the inner diameter of the firing tube 620, ensuring a tight fit between the piston ring 654 and the inner wall of the firing tube 620. When the gas generated by the firing nail structure enters the firing tube 620 through the connecting pipe 621, the high-pressure gas acts on the side of the piston ring 654 facing the firing gas and pushes the piston rod 651 to move along the firing tube 620. At the same time, the fit between the piston ring 654 and the inner wall of the firing tube 620 restricts the leakage of high-pressure gas from the gap between the piston ring 654 and the inner wall of the firing tube 620, allowing the gas generated by firing to act more concentratedly on the piston rod 651, thereby ensuring that the piston rod 651 can obtain sufficient driving force to fire the nail out of the nail tube 630.

[0060] After the piston rod 651 completes one nail-firing action, the directional locking block 660 engages again with the annular groove 653 on the piston rod 651. By restricting the position of the piston rod 651, the firing tube 620 moves in the opposite direction relative to the piston rod 651, thereby completing the reset of the piston rod 651. Thus, the annular groove 653 and the directional locking block 660 are mainly used to achieve the mechanical limiting and reset of the piston rod 651, while the piston ring 654 set in the annular groove 653 is used to withstand the firing gas entering the firing tube 620 and improve the effectiveness of the gas acting on the piston rod 651. Together, they realize the firing and reset process of the piston rod 651.

[0061] Furthermore, the directional locking block 660 includes a guide block 661 and a locking block 662. The locking block 662 protrudes from the guide block 661 and is used to cooperate with the piston rod 651. The back of the locking block 662 is provided with a limiting groove 663, which cooperates with the top tube sleeve to limit the position of the directional locking block 660. The launching tube 620 and the nail tube sleeve 670 are respectively provided with through grooves for the locking block 662 to pass through. The outer side of the frame 610 is provided with a sliding groove 611 adapted to the guide block 661.

[0062] Specifically, the guide block 661 is disposed within a slide groove 611 outside the frame 610, and can move along the slide groove 611 or remain in a predetermined position. The locking block 662 protrudes from the guide block 661 toward the firing tube 620. The firing tube 620 and the nail tube sleeve 670 are respectively provided with through grooves corresponding to the locking block 662, allowing the locking block 662 to pass through the through grooves at corresponding positions on the firing tube 620 and the nail tube sleeve 670 and extend into the position corresponding to the piston rod 651, thereby enabling the locking block 662 to form a locking engagement with the annular groove 653 on the piston rod 651. Through the above arrangement, when the firing tube 620 and the nail tube sleeve 670 move relative to the frame 610, the locking block 662 can move relative to the corresponding through groove, while avoiding interference between the firing tube 620 and the nail tube sleeve 670 and the movement of the locking block 662.

[0063] During piston rod 651 reset, locking block 662 engages with annular groove 653 on piston rod 651, allowing launch tube 620 and pin sleeve 670 to move relative to the fixed frame 610. Because guide block 661 matches slide groove 611 on frame 610, directional locking block 660 is guided and positionally constrained by slide groove 611, maintaining the correspondence between locking block 662 and annular groove 653 on piston rod 651. As launch tube 620 and pin sleeve 670 continue to move, locking block 662 can move relative to each other within the corresponding through groove, while piston rod 651, limited by locking block 662, cannot move synchronously with launch tube 620. This causes piston rod 651 to move relative to launch tube 620, achieving piston rod 651 reset.

[0064] Furthermore, the limiting groove 663 on the back of the locking block 662 cooperates with the top tube sleeve to further restrict the position of the directional locking block 660. When the directional locking block 660 is in the predetermined installation position, the top tube sleeve and the limiting groove 663 cooperate to constrain the position of the locking block 662 and the guide block 661, so that the locking block 662 can maintain its position extending into the corresponding through groove of the firing tube 620 and the nail tube sleeve 670. Thus, the sliding groove 611 is mainly used to guide and hold the guide block 661, the through groove is used to provide space for the locking block 662 to pass through and move relatively, and the limiting groove 663 and the top tube sleeve are used to further limit the directional locking block 660, so that the directional locking block 660 can maintain a stable cooperation with the piston rod 651 during the reciprocating movement of the firing tube 620, ensuring that the piston rod 651 can reliably complete the reset action.

[0065] Furthermore, the piston rod 651 has a force-receiving groove 652 at its end, which is used to withstand the force of the firing gas entering the firing tube 620 through the connecting pipe 621. The connecting pipe 621 is connected to the inside of the firing tube 620. After the nail structure completes firing, the gas generated by firing enters the connecting pipe 621 through the firing channel 121 and then enters the inside of the firing tube 620 through the connecting pipe 621. When the gas enters the firing tube 620, the gas can act on the force-receiving groove 652 at the end of the piston rod 651, applying pressure to the groove wall of the force-receiving groove 652, thereby generating a driving force on the piston rod 651 along the axial direction of the firing tube 620, causing the piston rod 651 to move rapidly inside the firing tube 620.

[0066] Specifically, after the firing gas enters the firing tube 620 through the connecting pipe 621, it creates gas pressure inside the firing tube 620. The force-receiving groove 652 provides the interaction area between the gas and the piston rod 651, allowing the gas entering the firing tube 620 to directly act on the piston rod 651. As the gas pressure acts on the force-receiving groove 652, the piston rod 651 is driven by a force along its axial direction and moves along the firing tube 620 towards the nail tube 630. After the piston rod 651 moves to the front end of the firing tube 620, it applies an impact force to the nail in the nail tube 630, causing the nail to move along the nail tube 630 and be ejected from the nail tube 630, thereby completing the nail firing operation.

[0067] The force-receiving groove 652 provided at the end of the piston rod 651 allows the firing gas delivered by the connecting pipe 621 to form an effective action area on the piston rod 651, converting the pressure generated by the firing gas into the axial movement of the piston rod 651. This enables the piston rod 651 inside the firing tube 620 to move due to the firing action of the nail structure, and further completes the continuous force transmission process of the nail.

[0068] Furthermore, the nail tube sleeve 670 is at least partially fitted onto the outside of the frame 610, forming a fitted fit between the nail tube sleeve 670 and the frame 610, and allowing the nail tube sleeve 670 to move relative to the outside of the frame 610. The sheath 640, the nail tube 630, the nail tube sleeve 670, and the firing tube 620 are interconnected to form an integral moving assembly, so that when the operator applies force to the sheath 640, the sheath 640, the nail tube 630, the nail tube sleeve 670, and the firing tube 620 can move synchronously relative to the frame 610.

[0069] Specifically, the frame 610 is fixedly installed inside the nail gun's housing. During the reset operation, the operator holds the protective sleeve 640 and pushes or pulls it in a predetermined direction. Because the protective sleeve 640, nail tube 630, nail tube sleeve 670, and firing tube 620 maintain a relatively fixed relationship, the force on the protective sleeve 640 can be sequentially transmitted to the aforementioned components, causing the protective sleeve 640, nail tube 630, nail tube sleeve 670, and firing tube 620 to move as a whole relative to the frame 610. Since the frame 610 serves as a fixed reference, and the firing tube 620 can move relative to the frame 610, the movement of the firing tube 620 can further drive the related components that cooperate with it to produce corresponding reset actions.

[0070] During the overall movement process described above, the directional locking block 660, located outside the frame 610, can engage with the piston rod 651. When the launching tube 620 moves relative to the frame 610 along with the overall moving assembly, the directional locking block 660 restricts the position of the piston rod 651, preventing the piston rod 651 from moving completely synchronously with the launching tube 620. This creates a relative displacement between the piston rod 651 and the launching tube 620, thereby allowing the piston rod 651 to reset using the overall movement of the launching tube 620.

[0071] Simultaneously, after the firing tube 620 moves to a predetermined position relative to the frame 610, it can also cooperate with the push rod 400 in the nail-shooting structure, further transforming the movement of the firing tube 620 into a pushing action of the push rod 400 on the reset block 210, which in turn drives the firing unit to reset. Therefore, by setting the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 as a structure capable of moving as a whole relative to the fixed frame 610, the same overall movement process can act on the piston rod 651 and the nail-shooting structure respectively, providing a motion basis for the reset of the firing part and the firing part of the nail gun.

[0072] Furthermore, the magazine compartment 810 is through-connected within the first magazine housing 600, allowing magazines to be inserted into and move within the magazine compartment 810 along its through-connection direction. The receiver frame 610 is also through-connected at a position corresponding to the magazine compartment 810, thus creating a continuous space between the magazine compartment 810 and the receiver frame 610 for magazines to pass through. This allows magazines located within the first magazine housing 600 to pass through the corresponding position on the receiver frame 610 and align with the magazine channel 114 of the nail gun structure.

[0073] Specifically, the magazine compartment 810 is connected to the magazine channel 114 of the nail gun structure, allowing the magazine installed in the magazine compartment 810 to move in a predetermined direction toward the nail gun structure and enter the magazine channel 114. Since the magazine compartment 810 and the receiver 610 are connected at corresponding positions, the receiver 610 will not obstruct the movement path of the magazine, and the magazine can move continuously between the magazine compartment 810, the receiver 610, and the magazine channel 114.

[0074] After a nail firing operation is completed, the next bullet in the magazine needs to be moved to the firing position corresponding to the firing channel 121. At this time, the magazine can move upward within the magazine channel 114, and the magazine channel 114 restricts and guides its movement direction. Since the magazine channel 114 is connected to the magazine magazine 810, the magazine can continuously enter the magazine channel 114 from the magazine magazine 810, so that subsequent bullets in the magazine can move sequentially to the firing position of the nail firing structure. The through structure provides a continuous movement path for the magazine inside the nail gun, while avoiding the frame 610 from obstructing the movement of the magazine, thereby ensuring that the magazine can move smoothly after completing one firing and provide bullets for the next firing.

[0075] It should be noted that the embodiments of this application only disclose the main structure of the nail gun itself. The magazine is an independent external accessory and is not the structure to be protected in this application. Therefore, the specification of this application does not limit or describe the specific structure, size, molding method and assembly details of the magazine.

[0076] Specifically, this application achieves this by providing a magazine compartment 810, a magazine passage 114, and... Figure 1 The structure, including its adaptable components, forms a mating structure for installing, accommodating, and guiding the magazine. This enables the assembly and installation of the external magazine, vertical sliding feeding, and obstacle avoidance functions, meeting the feeding requirements of the nail gun for continuous firing. The magazine body itself is not within the scope of innovation and protection of this application.

[0077] Therefore, those skilled in the art can select a matching external magazine according to actual assembly requirements. As long as it can be adapted to the magazine compartment 810 and magazine channel 114 of the nail gun of this application and realize the sliding feeding function, it falls within the scope of application of this application. This application does not make any specific limitations.

[0078] Example 3 Please see Figure 1 This invention provides a method for using a nail gun, employing the nail gun described in any one of Embodiment 2, comprising: The sheath 640, nail tube 630, nail tube sleeve 670 and firing tube 620 are moved relative to the frame 610 in the first direction. The movement of piston rod 651 is restricted by directional locking block 660, so that piston rod 651 moves relative to firing tube 620 and completes reset. The sheath 640, nail tube 630, nail tube sleeve 670 and firing tube 620 are moved relative to the frame 610 in a second direction opposite to the first direction. The firing tube 620 pushes the push rod 400, which in turn pushes the reset block 210 and puts the nail firing structure into the firing state. The trigger 310 is driven, causing the firing lever 320 to drive the firing element 220 to move and release the engagement between the firing element 220 and the firing pin body 230. The firing pin body 230 then fires the projectile under the action of the firing spring 237. The gas generated by the projectile enters the firing tube 620 through the connecting tube 621 and acts on the piston rod 651, driving the piston rod 651 to move and complete the nail firing operation through the nail tube 630.

[0079] In this embodiment, a method of using a nail gun involves using the aforementioned nail gun to perform nailing operations. Before nailing, the nail gun needs to be reset so that the firing part and the firing part are restored to a state where they can perform the next nailing operation.

[0080] Specifically, the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 are moved relative to the frame 610 along a first direction. During this movement, since the frame 610 serves as a relatively fixed reference, the directional locking block 660 mounted on the frame 610 can engage with the piston rod 651 and restrict its movement, preventing it from moving completely synchronously with the firing tube 620. As the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 continue to move relative to the frame 610 along the first direction, a relative displacement occurs between the piston rod 651 and the firing tube 620, causing the piston rod 651 to move along the firing tube 620 to a predetermined reset position, thereby completing the reset of the piston rod 651.

[0081] After the piston rod 651 is reset, the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 move relative to the frame 610 in a second direction opposite to the first direction. During this process, the firing tube 620 moves synchronously with the sheath 640, nail tube 630, and nail tube sleeve 670, and engages with the push rod 400 in the nail firing structure. As the firing tube 620 continues to move in the second direction, it pushes the push rod 400, causing the push rod 400 to exert a pushing force on the reset block 210. Under the action of the push rod 400, the reset block 210 moves in a predetermined direction, driving the firing element 220 disposed within the reset block 210 to move accordingly.

[0082] During the movement of the firing element 220 driven by the reset block 210, the firing element 220 can move along the reset ramp 233 of the firing pin body 230, causing a corresponding displacement of the firing element 220 relative to the firing pin body 230, and causing the locking block 223 on the firing element 220 to re-engage with the locking groove 232 on the firing pin body 230. Through the above-mentioned locking relationship, the firing element 220 and the firing pin body 230 are re-established, enabling the firing element 220 to limit the firing pin body 230 and restoring the nail gun structure to the firing ready state. At this time, the firing pin body 230 is limited by the firing element 220, and the firing spring 237 is in an energy-storing state capable of driving the firing pin body 230 to fire.

[0083] After the nail gun completes the aforementioned reset and enters the firing state, the trigger 310 is activated, causing the firing lever 320 to move. The firing lever 320 engages with the firing element 220 and, driven by the trigger 310, moves the firing element 220, causing the locking block 223 on the firing element 220 to gradually disengage from the locking groove 232 of the firing pin body 230. Once the locking block 223 is completely disengaged from the locking groove 232, the firing element 220 and the firing pin body 230 are released from engagement, and the firing pin body 230 is no longer limited by the firing element 220.

[0084] At this time, the firing spring 237 releases its stored elastic potential energy and acts on the firing pin body 230, causing the firing pin body 230 to move rapidly along the firing direction and fire the projectile located at the firing position. After being acted upon by the firing pin body 230, the projectile is fired, generating gas to drive the piston rod 651.

[0085] The gas enters the connecting tube 621 through the firing channel 121 of the nail-shooting structure, and then enters the firing tube 620 through the connecting tube 621. The gas entering the firing tube 620 acts on the piston rod 651, causing the piston rod 651 to be driven along the direction of the firing tube 620 and move along the firing tube 620 towards the nail tube 630. As the piston rod 651 continues to move, it applies a force to the nail through the nail tube 630, causing the nail to move along the nail tube 630 and be ejected from the nail tube 630, thus completing one nail-shooting operation.

[0086] After completing the aforementioned nail-shooting operation, the nail gun can be reset according to the aforementioned steps. First, the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 move relative to the frame 610 along a first direction to restrict the piston rod 651 via the directional locking block 660 and reset the piston rod 651. Then, these components move along a second direction opposite to the first direction, pushing the push rod 400 via the firing tube 620. This causes the reset block 210 to engage the firing element 220 with the firing pin body 230 again, thus restoring the nail gun to the ready state required for the next firing. Therefore, by moving the sheath 640, nail tube 630, nail tube sleeve 670, and firing tube 620 sequentially in opposite directions, the piston rod 651 resets, the firing mechanism resets, and preparation for the next firing is completed in a predetermined sequence, forming a continuous nail-shooting operation process.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
