Description

Technical Field

[0001] This patent application belongs to the field of nail gun technology, and specifically refers to a clamping device. Background Technology

[0002] Referring to the Chinese invention patent 2013105667854, a C-type nail gun nail ring engagement diameter adjustment device is disclosed, which includes a gun body, a clamping device and a driving cylinder on the gun body. The driving cylinder is located at the tail of the clamping device. The driving cylinder is composed of a cylinder sliding rod and a cylinder housing. The cylinder sliding rod is connected to a push block on the clamping device.

[0003] The invention patent has the following defects: When the cylinder sliding rod moves toward the clamping device, it will drive the push block to push the C-shaped nail located in the clamping device, and the left and right ends of the C-shaped nail will push open the clamping device to enter the installation groove in the jaws, so that the clamping device can clamp again to install the C-shaped nail; during the process of the C-shaped nail pushing open the clamping device, it will receive a reaction force from the clamping device, which will cause the C-shaped nail to deform, thus affecting the normal installation of the C-shaped nail. If the deformation is severe, the C-shaped nail may fall out of the installation groove in the jaws. Summary of the Invention

[0004] The purpose of this patent application is to provide a clamping device.

[0005] The purpose of this patent application is achieved as follows:

[0006] The clamping device includes:

[0007] Clamp support components;

[0008] The left and right clamps are rotatably mounted in the clamp support component; the left and right clamps are provided with clamping ends and driving ends, a clamping jaw is formed between the clamping ends of the left and right clamps, and a driving opening is formed between the driving ends of the left and right clamps.

[0009] A functional component is slidably disposed in the left and right jaws. The functional component is used to push the C-shaped pin to the clamping jaws and to close the clamping jaws by sliding the functional component.

[0010] as well as

[0011] A reset element is connected to the drive ends of the left and right jaws to provide a force for the drive opening to open the clamping jaws automatically.

[0012] Furthermore, the reset component includes two reset springs respectively connected to the clamping ends of the left and right clamps, and the two reset springs respectively push the clamping ends of the left and right clamps inward to clamp.

[0013] Furthermore, the reset component includes a tension spring connected between the clamping ends of the left and right clamps, which drives the clamping ends of the left and right clamps to clamp inward.

[0014] Furthermore, the clamp support component includes two opposing clamp mounting plates, with the left clamp and the right clamp rotatably connected between the two clamp mounting plates; the clamp mounting plates are provided with reset mounting plates, and the reset mounting plates are provided with reset mounting portions extending between the two reset mounting plates, with the reset spring provided between the reset mounting portions and the corresponding clamping ends.

[0015] Furthermore, the clamp support component also includes a clamp connecting block, which includes a first connecting end connected between the two clamp mounting plates and a second connecting end for connecting the push pin device, wherein the first connecting end and the second connecting end are arranged perpendicularly to each other.

[0016] Furthermore, the left and right clamps are provided with recessed cavities, and the recessed cavities on the left and right clamps are joined together to form a movable cavity; the movable cavity includes a clearance portion for the sliding of the functional component, and a closing portion on the side adjacent to the drive opening, and the functional component slides along the closing portion to open the drive opening so as to close the clamping jaws.

[0017] Furthermore, the length of the constricted portion in the direction of movement of the functional component is one-third to one-fifth of the length of the movable cavity in the direction of movement of the functional component.

[0018] Furthermore, the functional component includes several rollers that slide within the movable cavity, the rollers being used to contact the closing portion and open the drive opening.

[0019] Furthermore, the functional component also includes a pusher piece that slides within the movable cavity. The left and right jaws are provided with a separating protrusion, and the separating protrusion is provided with a pusher groove for the pusher piece to slide, so as to push the C-shaped nail to the clamping jaws through the pusher piece.

[0020] Furthermore, the clamp mounting plate is also provided with a guide spring, and the guide spring is provided with a guide protrusion located inside the clamping jaws. The guide protrusion is on the feeding path of the C-shaped nail, and the guide protrusion has a sliding surface for abutting against the C-shaped nail, and an abutting surface for abutting against the back of the C-shaped nail.

[0021] The outstanding and beneficial technical effects of this patent application compared to the prior art are:

[0022] Because the left and right clamps in this patent are equipped with reset components, the reset components will drive the left and right clamps to close the drive opening the moment the functional component leaves the drive opening, thereby opening the clamping jaws. This ensures that the C-shaped nail will not abut against the left and right clamps during the process of the functional component pushing the C-shaped nail. Therefore, the C-shaped nail will not be deformed due to the reaction force of the left and right clamps, and thus will not affect the normal installation of the C-shaped nail. This effectively prevents the C-shaped nail from falling out of the clamping jaws due to deformation.

[0023] The pusher device in this patent operates smoothly and compactly, allowing the user to automatically push the C-shaped nail into the clamping jaws after completing a nailing action, and causing the functional components of the pusher rod to retract to the front of the drive opening, so as to quickly start the next nailing action and increase the overall nailing efficiency.

[0040] The present patent application will be further described below with reference to specific embodiments:

[0041] A clamping device for use in a C-shaped nail gun includes a nail-pushing device 1, a clamping device 2, and a nail-feeding device 3. The nail-pushing device 1 slides and drives a nail-pushing rod 4. A functional component is provided at one end of the nail-pushing rod 4. The clamping device 2 includes a clamping support component and a left clamping part 21 and a right clamping part 22 rotatably configured in the clamping support component. The left clamping part 21 and the right clamping part 22 are provided with a clamping end 225 and a driving end 226. A clamping jaw 24 is formed between the clamping end 225 of the left clamping part 21 and the right clamping part 22, and a driving opening 23 is formed between the driving end 226 of the left clamping part 21 and the right clamping part 22. The nail-feeding device 3 is connected to the clamping device 2 and is used to feed C-shaped nails into the clamping device 2. The functional component is driven by the nail-pushing rod 4 to slide and is used to push the C-shaped nails to the clamping jaw 24 and to control the opening of the clamping jaw 24 by the sliding of the functional component.

[0042] Specifically, such as Figure 1 , 2 As shown, the push-nail device 1 in this patent includes a housing 11, which can be divided into four parts: a first receiving part 111 and a second receiving part 112, which are arranged vertically front to back; a third receiving part 113, which is arranged horizontally on the top of the first receiving part 111 and the second receiving part 112; and a fourth receiving part 114, which is arranged horizontally on the lower end of the first receiving part 111 and the second receiving part 112. The first receiving part 111, the second receiving part 112, the third receiving part 113, and the fourth receiving part 114 are integrally formed into a complete housing 11. In fact, the housing 11 in this embodiment is formed by splicing two oriented half-shells together, and the first receiving part 111, the second receiving part 112, the third receiving part 113, and the fourth receiving part 114 are formed after the two half-shells are spliced ​​together.

[0043] The pusher pin device 1 also includes a sliding seat 12, in which a sliding member 13 is slidably disposed, and the sliding member 13 is connected to the pusher pin rod 4. A force supply component 14 is provided in the sliding seat 12 to abut against the sliding member 13. Figure 6 , 7 As shown, the sliding seat 12 is installed in the third receiving portion 113, and the third receiving portion 113 has a cavity adapted to the shape of the sliding seat 12. The sliding seat 12 includes support portions 121 located at its front and rear ends, a sliding rod connected between the two support portions 121, and two side fixing plates 122. The two ends of the side fixing plates 122 are respectively connected to the two support portions 121. The sliding member 13 is slidably disposed on the sliding rod 123, and a force supply component 14 is fitted on the sliding rod 123. In this embodiment, the force supply component 14 is specifically fitted on the sliding rod 123, and its two ends abut against the sliding member 13 and the support portion 121 respectively. The force supply spring can take many forms. For example, in this embodiment, only one force supply spring is provided. In other embodiments, the user can also set multiple force supply springs to increase the driving force according to the needs, such as using multiple intertwined force supply springs or two force supply springs arranged on the left and right.

[0044] In fact, the top of the third receiving portion 113 is provided with an openable and closable top cover 115, and the third receiving portion 113 under the top cover 115 has an installation space formed to fit the shape of the sliding seat 12. Figure 6 , 7 As shown, the front end of the top cover 115 is fixed to the support portion 121 located at the front end of the sliding seat 12 by screws.

[0045] The pusher pin device 1 further includes a power mechanism 15, which includes a motor, a reducer, and a drive wheel 16. The drive wheel 16 has a release part 161 and a push part 162. The push part 162 is provided with a plurality of push pins 163, and the sliding member 13 is provided with an abutment end 131 that abuts against the push pins 163. Figure 6 , 8 As shown, the drive motor is installed in the second receiving part 112. The drive wheel 16 is connected to the drive shaft of the drive motor. The drive wheel 16 is specifically a cam. One side of the cam is the pushing part 162, and the other side of the cam is the releasing part 161. The cam on the pushing part 162 is provided with a protruding pushing pin 163. Specifically, when the drive wheel 16 rotates so that its pushing part 162 is opposite to the abutting end 131, a plurality of the pushing pins 163 on the pushing part 162 abut against the abutting end 131 in sequence to make the sliding member 13 slide in the opposite direction of the push pin; when the drive wheel 16 rotates so that its releasing part 161 is opposite to the abutting end 131, the sliding member 13 slides in the direction of the push pin under the action of the force supply component 14.

[0046] In addition, a buffer 133 is fixed on the support 121 at the front end of the sliding seat 12 for abutting against the sliding member 13. The buffer 133 can be made of flexible material and is used to buffer when the sliding member 13 collides with the support 121 at the front end of the sliding seat 12 under the action of the force supply component 14, so as to reduce noise.

[0047] refer to Figure 2 , 7 As shown in Figure 8, the outer edge of the sliding member 13 is provided with a protruding sliding bracket 132. The upper end of the sliding bracket 132 and one end of the push rod 4 are provided with opposing pin holes 43. The two are connected by setting a pin in the pin hole 43. The lower end of the sliding bracket 132 is close to the drive wheel 16, and the abutment end 131 is formed on it. The abutment end 131 is used to abut against the drive wheel 16 to realize the sliding of the sliding member 13. The abutting end 131 includes a long abutting plate 1311 and a short abutting plate 1312 arranged front and rear on the sliding member 13. The pushing pin 163 includes a long pushing pin 1631 and a short pushing pin 1632. When the drive wheel 16 rotates, the short pushing pin 1632 pushes the long abutting plate 1311 to drive the sliding member 13 to slide, and then the long pushing pin 1631 pushes the short abutting plate 1312 to drive the sliding member 13 to slide. The sliding member 13 is driven by the alternating abutting of the long pushing pin 1631 and the short pushing pin 1632.

[0048] Furthermore, the fourth receiving portion 114 is provided with a circuit board and a power supply for driving the power mechanism 15, while the first receiving portion 111 is provided with operation buttons. Therefore, the first receiving portion 111 is used for users to hold and operate to control the movement of the power mechanism 15. The power mechanism 15 in the second receiving portion 112 is powered by the battery and circuit board in the fourth receiving portion 114.

[0049] In addition, such as Figure 6 As shown, the sliding seat 12 is provided with a detection element 17 located on the sliding trajectory of the sliding member 13; when the detection element 17 detects the sliding member 13, the functional component on the push rod 4 is located in front of the drive opening 23, and the power mechanism 15 is stopped by the detection element 17. Figure 6 As shown, the detection element 17 is specifically a trigger switch installed on the side fixing plate 122. When the sliding member 13 slides, it will contact the trigger switch, thereby controlling the drive motor to stop through the detection element 17.

[0050] Considering that different nail guns have clamping devices 2 of different sizes, and that different sizes of clamping devices 2 require different sliding distances of push rods 4, this patent provides a contact part 134 extending on one side of the sliding member 13 in the sliding direction of the sliding member 13. The contact part 134 is specifically an annular sleeve that is fitted onto the sliding rod and connected to the sliding member. The contact part 134 is used to abut against the detection element 17 when the sliding member 13 slides. By increasing the lateral length of the entire sliding member 13 through the contact part 134, the sliding member 13 can be released from the detection element 17 in advance when it slides, thus adapting to clamping devices 2 of different sizes.

[0051] The clamping device 2 is fixed to the front end of the third receiving portion 113, such as Figure 3 , 5As shown, the clamp support component includes two vertically opposed clamp mounting plates 27. One end of each clamp mounting plate 27 is provided with a clamp connecting block 271 connecting between the clamp mounting plates 27. The clamp connecting block 271 has a first connecting end 2711 connecting between the two clamp mounting plates 27, and a second connecting end 2712 for overlapping the end face of the support part 121. The first connecting end 2711 and the second connecting end 2712 are arranged perpendicularly, allowing the second connecting end 2712 to be connected to the upper end face of the support part 121 by screws, thereby connecting the first connecting end 2711 between the two vertically arranged clamp connecting blocks 271. At this time, the clamp connecting block 271 and the top cover 115 are respectively connected to the support part 121 front and rear. The user can directly remove the top cover 115 for maintenance by screws, and at the same time, remove the pin located in the pin hole 43. Then, the entire clamp mechanism 2 can be removed by disassembling the clamp connecting block 271 on the support part 121.

[0052] An installation space is formed between the two clamp mounting plates 27. The left clamp 21 and the right clamp 22 are rotatably connected between the two clamp mounting plates 27, and are positioned and fixed by the clamp mounting plates 27. The front and rear ends of the left clamp 21 and the right clamp 22 are respectively the clamping end 225 and the driving end 226. Both the clamping end 225 and the driving end 226 are bent. A clamping jaw 24 is formed between the clamping end 225 of the left clamp 21 and the right clamp 22, and a driving opening 23 is formed between the driving end 226 of the left clamp 21 and the right clamp 22.

[0053] A raised separating protrusion 26 is provided at the rotational connection point of the left clamp 21 and the right clamp 22. The left clamp 21 and the right clamp 22, facing the drive opening 23, have recessed cavities. These cavities connect to form a movable cavity 222. A functional component on the pusher rod 4 extends into the movable cavity 222 and slides within it. Specifically, the movable cavity 222 includes a clearance portion 2222 for the sliding of the functional component and a closing portion 2221 adjacent to the drive opening 23. The functional component can slide along the closing portion 2221 to open the drive opening 23, or slide within the clearance portion 2222 to push the C-shaped nail.

[0054] It should be noted that the left clamp 21 and the right clamp 22 have a semi-circular groove on one end of the drive opening 23. The two semi-circular grooves are joined together to form a circular hole. Correspondingly, the clamp connecting block 271 also has a circular hole. The push rod 4 passes through the above-mentioned circular hole in sequence through the clamp connecting block 271 and the drive opening 23 into the movable cavity 222. The semi-circular groove allows the push rod 4 to pass into the movable cavity 222 even when the drive opening 2 is closed.

[0055] The functional components include a plurality of rollers 41 disposed on the end of the pusher rod 4, such as Figure 2 As shown, four rollers 41 are provided, each connected in pairs to the front and rear sides of the end of the pusher rod 4. When the pusher rod 4 slides toward the drive opening 23, it slides along the closing portion 2221 via the rollers 41 to gradually push open the drive opening 23, thereby causing the left clamp 21 and right clamp 22 to rotate and clamp the clamping jaws 24 formed on the other end of the left clamp 21 and right clamp 22. The functional component also includes a pusher plate 42 connected to the end of the pusher rod 4. The pusher plate 42 is located entirely in the clearance portion 2222 of the movable cavity 222. A pusher groove 261 is provided on the separating protrusion 26 of the left clamp 21 and right clamp 22 for the pusher plate 42 to slide. During the sliding process, the pusher rod 4 passes through the pusher groove 261 to push the C-shaped nail located in the pusher cavity 223 and make it enter the clamping jaws 24. The purpose of setting the dividing protrusion 26 is to place the C-shaped nail into the movable cavity 222, and also to effectively restrict the movement of the push rod 4.

[0056] To facilitate user operation of the C-shaped nail gun described in this patent, such as Figure 11 As shown, an operating handle 272 is fixed to one of the clamp mounting plates 27 by screws for direct gripping and operation by the user. In addition, to increase the stability of the clamp device 2 after installation, a support plate 116 is fixed to the front side of the second receiving part 112 of the housing 11. The support plate 116 extends upward and is connected and fixed to the side of the clamp mounting plate 27.

[0057] The nail feeding device 3 is fixed to one side of the clamping device 2. The left clamping part 21 and the right clamping part 22 on the side of the separating protrusion 26 facing the clamping jaw 24 are similarly bent to form a nail-pushing cavity 223 for accommodating C-shaped nails. See the specific reference. Figure 3 , 4 The nail feeding device 3 includes a nail guide rod 31 connected to one side of the clamping device 2. An elastic coil spring 32 is provided on one side of the nail guide rod 31, and a nail pusher block 33 is connected to one end of the elastic coil spring 32. The nail guide rod 31 is arranged with C-shaped nail rows. The nail block 33 on the end of the elastic coil spring 32 is located at the end of the C-shaped nail rows. The C-shaped nails on the nail guide rod 31 are gradually pushed into the nail pusher cavity 223 in the clamping device 2 by the bending force of the elastic coil spring 32, and then pushed into the clamping jaw 24 by the functional component on the nail pusher rod 4.

[0058] Furthermore, it also includes a reset member 29, which is connected to the drive ends 226 of the left jaw 21 and the right jaw 22, and is used to provide a force for opening the clamping jaws 24, so that the clamping jaws 24 open automatically. Figure 3 ,5 As shown, a reset mounting plate 28 is provided on one of the clamp mounting plates 27. The reset mounting plate 28 is directly covered on the clamp mounting plate 27 by screws. The reset mounting plate 28 is provided with a reset mounting part 281 offset between the two clamp mounting plates 27. The reset part 281 is provided with the reset member 29.

[0059] The reset component 29 in this patent is a reset spring. One end of the reset spring is fitted onto the reset mounting portion 281, and the other end abuts against the drive end 226 of the left clamp portion 21 / right clamp portion 22. In this patent, to stabilize the installation of the reset spring, spring grooves 224 for accommodating the reset spring are provided on the left clamp portion 21 and the right clamp portion 22.

[0060] The C-shaped nail gun in this patent is used as follows:

[0061] In the initial state, there are no C-shaped nails in the clamping jaws 24. The nail feeding device 3 feeds the C-shaped nails into the pushing cavity 223. At this time, the user controls the rotation of the power mechanism 15 through the button on the nail gun. Since the power mechanism 15 in this patent application uses a drive motor, after the drive motor rotates, the drive motor drives the drive wheel 16 to rotate through the reducer, so that the push pin 163 on the drive wheel 16 acts on the abutment end 131 of the sliding member 13, and pushes the sliding member 13 to slide in the opposite direction of the push nail against the force supply component 14, so that the push nail rod 4 slides, and the functional component slides in the avoidance part 2222 of the movable cavity 222 until the functional component slides to the closing part 2221 and opens the drive opening 23, allowing the push nail rod 4 to slide. The drive opening 23 is opened to clamp the clamping jaws 24; then, the drive motor drives the drive wheel 16 to continue rotating, so that the release part 161 on the drive wheel 16 is opposite to the sliding member 13. The sliding member 13 is no longer limited by the push pin 163 and slides in the push pin direction under the action of the force supply component 14, so that the push pin rod 4 moves toward the clamping jaws 24, and the functional component on the push pin rod 4 pushes the C-shaped nail in the push pin cavity 223 into the clamping jaws 24.

[0062] At this point, the C-nail gun begins normal operation. After the C-nail is in the clamping jaws 24, the user controls the drive motor to start via an operation button. This drives the sliding member 13 to slide in the opposite direction to the force supply component 14, causing the functional component to open the drive opening 23, so that the clamping jaws 24 clamp the C-nail inside, thus driving the nail. Then, the drive motor continues to rotate. When the release part 161 on the drive wheel 16 is opposite to the sliding member 13, the sliding member 13 slides under the action of the force supply component 14, pushing the C-nail in the nail pusher cavity 223 back into the clamping jaws 24. During the pushing process, since the left clamp 21 and right clamp 22 in this patent are provided with reset members 29, the reset members 29 will drive the left clamp 21 and right clamp 22 to close the drive opening 23 the moment the functional component leaves the drive opening 23, thereby opening the clamping jaws 24. This ensures that the C-shaped nail will not abut against the left clamp 21 and right clamp 22 during the pushing process of the functional component. Therefore, the C-shaped nail will not be deformed due to the reaction force of the left clamp 21 and right clamp 22, and thus will not affect the normal installation of the C-shaped nail. This effectively prevents the C-shaped nail from falling out of the clamping jaws 24 due to deformation.

[0063] Furthermore, since the sliding seat 12 in this patent is provided with a detection element 17 located on the sliding trajectory of the sliding member 13, the user can control the stopping position of the sliding member 13 according to the detection element 17, thereby controlling the entire working process of the nail gun.

[0064] Specifically, after the sliding member 13 is driven by the force supply component 14 to move in the direction of the pusher nail, the drive motor continues to rotate, causing the push pin 163 on the drive wheel 16 to abut against the sliding member 13 again, thereby pulling it to move in the opposite direction of the pusher nail until the sliding member 13 moves to the position of the detection component 17 and stops; at this time, the functional components on the pusher nail rod 4 will be driven to stop in front of the clamping jaws 24, that is, as Figure 9 As shown.

[0065] At this point, the C-shaped nail gun can be considered to be in a ready-to-nail state. Only when the user continues to activate the drive motor will the drive wheel 16 continue to rotate, causing the sliding member 13 to slide a short distance under the action of the push pin 163. This drives the functional component to slide into the drive opening 23, allowing the clamping jaws 24 to clamp and nail the component. Figure 10As shown. After the clamping jaws 24 have clamped and completed nailing, the drive motor continues to rotate, causing the release part 161 on the drive wheel 16 to face the sliding member 13. This causes the sliding member 13 to be immediately driven to slide in the nail-pushing direction under the action of the force supply component 14, driving the nail-pushing rod 4 to push the next C-shaped nail into the clamping jaws 24. After the C-shaped nail is pushed into the clamping jaws 24, the drive wheel 16 continues to rotate, causing its pushing part 162 to act again against the abutment end 131 on the sliding member 13, causing the sliding member 13 to slide in the opposite direction of the nail pusher. This drives the functional component on the nail-pushing rod 4 to slide in front of the clamping jaws 24 until the sliding member 13 contacts the detection component 17. At this time, the detection component 17 detects a signal to control the drive motor to stop, so that the functional component stops in front of the clamping jaws 24 and returns to the nail-placing state.

[0066] Since the drive motor continuously drives the drive wheel 16 to rotate, the clamping jaws 24 clamp, the sliding member 13 is driven to slide by the force supply component 14, and the pushing part 162 interacts with the abutment end 131 on the sliding member 13 to drive the functional component on the push rod 4 to slide to the front of the clamping jaws 24. These three actions are performed sequentially and continuously. The whole action is coherent and compact, which allows the user to automatically push the next C-shaped nail into the clamping jaws 24 after completing a nailing action and to make the functional component of the push rod 4 retract to the front of the drive opening 23. This allows the functional component to immediately contact the drive opening 23 for the next nailing action, increasing the overall nailing efficiency.

[0067] refer to Figure 9 , 10 The length of the closing part 2221 in the direction of movement of the functional component is one-third to one-fifth of the length of the movable cavity 222 in the direction of movement of the functional component. Its lateral length is small. Before and after the functional component retracts to the drive opening 23, the functional component only needs to slide a small section to open the drive opening 23 to achieve the clamping of the clamping jaws 24.

[0068] In other embodiments, the nail-pushing device 1 in this patent can also take other forms, such as being driven directly by a cylinder or a motor push rod. Compared to others, this patent completes the half-stroke action of the nail-pushing rod 4 by setting a power supply component 14. In contrast, a cylinder or a motor push rod requires full power to drive the nail-pushing rod 4 to move in both directions. Compared to these, the nail-pushing device 1 in this patent is more energy-efficient and has a better endurance.

[0069] In other embodiments, the reset member 29 includes a tension spring connected between the clamping ends 225 of the left clamp 21 and the right clamp 22. The tension spring drives the clamping ends 225 of the left clamp 21 and the right clamp 22 to clamp inward, which can also achieve the working purpose of this patent.

[0070] Furthermore, the clamp mounting plate 27 is also provided with a guide spring 273, and the guide spring 273 is provided with a guide protrusion 274 located inside the clamping jaws 24. Figure 11 , 4 As shown, the guide spring 273 is fixed to the outside of the clamp mounting plate 27 by screws, and extends into the pusher cavity 223. The guide protrusion 274 is formed on the surface of the guide spring 273 facing the pusher cavity 223, and the guide protrusion 274 is on the feeding path of the C-shaped nail. The guide protrusion 274 is used to contact the C-shaped nail when it is driven to slide. The inner side of the guide protrusion 274 facing the pusher cavity 223 is provided with a sliding surface 2741 for abutting against the C-shaped nail. The front end of the guide spring 273 is slightly biased towards the pusher cavity 223, thereby forming an inclined sliding surface 2741. During the sliding process of the C-shaped nail, one side of the C-shaped nail slides along the sliding surface 2741, and the guide spring 273 is bent by the push of the C-shaped nail, so that the guide protrusion 274 gradually moves outward, thereby allowing the C-shaped nail to continue to move forward into the clamping jaws 24. After the C-shaped nail is clamped into the jaws 24, the nail gun is about to drive the nail. At this time, the guide protrusion 274, under the action of the guide spring 273, is repositioned in the push-nail cavity 223 and located on the back of the C-shaped nail. The abutment surface 2742 is formed at the front end of the guide protrusion 274 and abuts against the back of the C-shaped nail. If the clamping jaws 23 clamp at this time, the C-shaped nail is also clamped. When existing nail guns clamp C-shaped nails, if the quality of the C-shaped nail is poor or the position of the C-shaped nail is incorrect, the C-shaped nail is easily clamped into a flat shape, resulting in insufficient fixation of the C-shaped nail. However, this patent uses the guide protrusion 274 to abut against the back of the C-shaped nail to make the C-shaped nail receive uniform force when clamped, so that it will not be pressed into a flat shape, thereby making the C-shaped nail more firmly fixed.

[0071] The above embodiments are merely preferred embodiments of this patent application and are not intended to limit the scope of protection of this patent application. Therefore, all equivalent changes made to the structure, shape, and principle of this patent application should be covered within the scope of protection of this patent application.
