Description

Technical Field

[0001] The utility model belongs to the technical field of snap ring nail clamping tools, and in particular relates to an electric snap ring nail gun and an execution device thereof. Background Art

[0002] A snap nail is a nail with an opening, including C-shaped nails, clamp nails, M-shaped nails, etc. It gradually closes the opening by acting on the edges on both sides of the opening. It is mainly used in situations where multiple bundles of metal wires need to be bundled, such as for bundling or fixing cages, metal nets, and cloth bags.

[0003] Existing tools for clamping snap rings mainly include manual and mechanical types. Manual tools are simple in structure and generally include a pair of handles for holding, with a nail magazine located between the handles. The snap rings in the magazine are pressed by manually pressing the handles. Mechanical tools generally include a pair of clamps located on the muzzle of a gun, which are mechanically controlled to close to clamp the snap rings in the magazine. Manual tools require manual pressing, which is inefficient and laborious, making them unsuitable for situations requiring long work periods.

[0004] Mechanical retaining ring nail clamping tools usually use a pull rod to force the clamp to close. A pair of rollers are installed on the pull rod. As the pull rod moves backward, the rollers move backward, and the circumference of the rollers rolls relative to the side walls of the clamp, thereby driving the clamp to rotate and close the front jaws to achieve the nail pressing operation. In existing equipment, the assembly position of the rollers is fixed. Therefore, if the pull rod moves too far backward during operation, it is easy to cause the front jaws to over-engage. After long-term and repeated over-engagement, it is easy to cause the clamp arm to wear or even fail, affecting the service life of the clamp arm. Even if the travel of the pull rod is set in advance, it is easy to cause the same problems as mentioned above due to unavoidable processing errors or assembly errors. Summary of the Invention

[0005] In order to solve the above problems, the utility model provides an electric buckle nail gun and an execution device thereof.

[0040] <Example 1>

[0041] This embodiment provides an electric snap ring nail gun for bending snap ring nails. In this embodiment, one of the snap ring nails 1 (C-shaped nail) is used as an example. Figure 1 , the structure of the snap ring nail 1 is shown in FIG. , and the snap ring nail 1 is C-shaped as a whole, with an open end 2 and a closed end 3. Figure 2 and Figure 3 An electric snap ring nail gun is shown, which includes a gun body 10, an actuator, a drive device 40, a power supply unit and a control unit, wherein the actuator includes a nozzle mechanism 20 and an actuator 30, the nozzle mechanism 20 is installed at the front end of the gun body 10, and has a nozzle 21, a nail magazine 22 for storing snap ring nails 1 and a blocking assembly 70, the actuator 30 is movably arranged on the nozzle 21, and is used to act on the snap ring nail 1, and the drive device 40 is installed in the gun body 10, and is used to drive the actuator 30 to work.

[0042] like Figure 2 As shown, the gun body 10 is formed by two front and rear cover plates 11 and 12, which are interlocked and fixed by screws. The interior forms a mounting cavity for mounting the drive device 40. The gun body 10 not only accommodates the drive device 40 and other internal components, but also protects these internal components. The gun body 10 includes a handle 13 for the user to hold and a base 14 connected to the handle 13. The handle 13 and the base 14 are both hollow structures. The power supply unit and the control unit are both disposed within the base 14. The power supply unit is used to power the entire electric buckle nail gun. The control unit is electrically connected to the power supply unit and is used to control the operation of the drive device.

[0043] like Figure 3As shown, the gun nozzle mechanism 20 is arranged at the front end of the gun body 10. The gun nozzle mechanism 20 has a plate-shaped gun nozzle 21, a nail magazine 22 for storing the snap ring nail 1, and a blocking assembly 70 for abutting against the rear side of the closed end 3 of the snap ring nail 1 when the snap ring nail 1 is pressed. The gun nozzle 21 is installed between the nail magazine 22 and the gun body 10. An actuator 30 for acting on the snap ring nail 1 is movably arranged above the gun nozzle 21. Figure 4 and Figure 5 As shown, the actuator 30 comprises a push rod 31, a pair of clamp arms (left clamp arm 32, right clamp arm 33), a pair of driving parts (in this embodiment, rollers are used to drive the driving parts, so the driving parts are the left roller 34 and the right roller 35), a pair of rotating parts (left rotating part 36, right rotating part 37), a fixing member 38 and a pressure plate 39. The left clamp arm 32 corresponds to the left roller 345 and the left rotating part 36, and the right clamp arm 33 corresponds to the right roller 35 and the right rotating part 37. Figure 5 As shown, the push rod 31 has a rod body, one end of the rod body is a fixed part 311 installed in the gun body, and the other end is a pushing part 312 for acting on the buckle nail 1 and pushing the buckle nail 1 to move. The middle part of the rod body also has a pulling part 313, and the pulling part 313 is located between the fixed part 311 and the pushing part 312. A pair of rollers (left roller 34 and right roller 35) are adjustably installed on the pulling part 313 through two adjusting parts (left adjusting part 343 and right adjusting part 353).

[0044] like Figure 4-Figure 7 As shown, the left roller 34 and the right roller 35 are both annular rollers with inner rings. The left adjusting member 343 and the right adjusting member 353 are respectively provided with connecting portions (left connecting portion 3431 and right connecting portion 3531) that extend into the inner rings of the left roller 34 and the right roller 35. The left connecting portion 3431 and the right connecting portion 3531 are also respectively provided with a left adjusting hole 3432 and a right adjusting hole 3532 that are eccentric to the inner rings of the left roller 34 and the right roller 35. The left roller 34 and the right roller 35 are installed on the pulling portion 313 of the push rod 31 through the left fixing member 61 and the right fixing member 62 through the left adjusting hole 3432 and the right adjusting hole 3532. Figure 6 As shown, in this embodiment, the left fixing member 61 and the right fixing member 62 are both bolts, and a pair of fixing holes (left fixing hole 3131 and right fixing hole 3132) are provided on the pulling portion 313 of the push rod 31, and a pair of strip holes (left strip hole 201 and right strip hole 202) are provided on the muzzle 21 along the moving direction (i.e., the length direction) of the push rod 31. A pair of fixing members pass through the corresponding adjustment holes, fixing holes and strip holes in sequence to be connected with nuts, thereby realizing the installation of the left roller 34 and the right roller 35.

[0045] When installing the left roller 34 and the right roller 35, the left connecting portion 3431 and the right connecting portion 3531 of the left adjusting member 343 and the right adjusting member 353 are extended into the inner ring of the left roller 34 and the inner ring of the right roller 35 respectively, and the left fixing member 61 and the right fixing member 62 are inserted into the left adjusting hole 3432 and the right adjusting hole 3532 respectively. Since the left adjusting hole 3432 and the right adjusting hole 3532 are eccentrically arranged with respect to the inner ring of the left roller 34 and the inner ring of the right roller 35 respectively, the center axis L1 of the left fixing member 61 and the right fixing member 62 are also eccentrically arranged with respect to the center axis L2 of the left roller 34 and the right roller 35. Therefore, the distance from any point on the outer ring of the left roller 34 and the right roller 35 to the center axis L1 of the left fixing member 61 and the right fixing member 62 is different. The installation position of the roller can be changed by rotating the roller and the adjusting member. Figure 7 As shown, in cross-section, the contact between the roller and the caliper arm is point-line contact (and a tangent line), that is, contact is made between a point on the outer circumference of the roller and the inner side of the caliper arm. The aforementioned eccentric adjustable structure allows the spacing between the central axis L1 and the caliper arm to be changed by rotating the roller and the adjusting member. Therefore, during assembly, the jaws of the caliper arm can be first adjusted to the optimal closed state, and then the installation position of the roller on the pulling portion 313 is adjusted. Finally, the fixing member and the nut are tightened to ensure that the caliper arm is in the optimal closed state when the roller is in this position. Even if the roller continues to move backward with the push rod 31 during use, it will not cause the front end of the caliper arm to close excessively, thereby protecting the caliper arm from wear or even failure due to excessive engagement.

[0046] A pair of clamp arms are respectively formed with a pressing portion for acting on the buckle nail 1 and a matching portion for matching with the corresponding roller, with their own rotating portions as boundaries. A jaw is opened at the front end of the pressing portion. The roller interacts with the matching portion during movement to cause the jaw to close, and the matching portion has a parallel matching section arranged parallel to the moving direction of the push rod and an inclined matching section arranged obliquely to the moving direction of the push rod; the pushing portion 312 interacts with the pressing portion during movement to cause the jaw to open.

[0047] like Figure 6 and Figure 7As shown, a through slot 211 is defined in the middle of the muzzle 21 along its length. A pair of planar guide plates 215 extending along the length are formed on either side of the through slot 211. The push rod 31 is movably mounted on the through slot 211. The left and right arms 32, 33 are pivotally mounted on the guide plates 215 on the left and right sides of the push rod 31 via a left pivoting portion 36 and a right pivoting portion 37, respectively. In this embodiment, the left and right arms 32, 33 have substantially identical structures. The left arm 32 will be used as an example for detailed description. The left arm 32, defined by its midsection where it connects to the left pivoting portion 36, has a mating portion 322 and a pressing portion 323 on either side. The mating portion 322 is configured to interact with the left roller 34 mounted on the push rod 31. When the push rod 31 moves toward the direction where the gun body is located, the left roller 34 and the right roller 35 can respectively roll along the matching portions 322 of the bent left and right clamp arms 32 and 33, thereby causing the pressing portions 323 of the left and right clamp arms 32 and 33 located at the front to rotate inward, so that the left jaws 321 and the right jaws 331 are brought closer to each other, thereby bending the snap ring nail 1. When the push rod 31 moves toward the side where the nail magazine 22 is located, the pushing portion 312 moves forward, carrying the snap ring nail 1, and can push open the pressing portions 323 of the left and right clamp arms 32 and 33 on both sides and rotate them outward, so that the left jaws 321 and the right jaws 331 are moved away from each other (open).

[0048] Specifically, the fitting portion 322 is bent, and the fitting portion 322 has a parallel fitting section 3221 arranged parallel to the moving direction of the push rod 31 and an inclined fitting section 3222 arranged obliquely to the moving direction of the push rod 31, and the end of the inclined fitting section 3222 close to the push rod 31 is provided with an embedding groove 324 for the side of the push rod 31 to be embedded. The front end of the pressing portion 323 is provided with the left jaw 321 for acting on the buckle nail 1, and the pressing portion 323 is formed with a groove structure at the bottom facing the push rod 31, allowing the pushing portion 312 to extend into and the two to contact. During the forward movement of the pushing portion 312, the interaction between the pushing portion 312 and the groove structure can push the two adjacent clamp arms apart and away from each other. In addition, in this embodiment, if Figure 5 As shown, the length of the inclined mating section 3222 on the left clamp arm 32 is greater than the length of the inclined mating section on the right clamp arm 33, and the length of the parallel mating section 3221 on the left clamp arm 32 is greater than the length of the parallel mating section on the right clamp arm 33. The staggered length design of the left and right clamp arms 32 and 33 allows the jaws to press the nail first on the side where the right clamp arm 33 is located, generating active force, while the side where the left clamp arm 32 is located generates passive force. This results in the final annular nail being formed with the left edge enveloping the right edge, ensuring that the open end 2 of the C-shaped nail can be completely closed and in the same plane.

[0049] In this embodiment, if Figure 6 As shown, the left rotating part 36 and the right rotating part 37 are both ring structures, which are respectively installed on the gun nozzle 21 through the left fixing pin 63 and the right fixing pin 64. The middle parts of the left clamp arm 32 and the right clamp arm 33 are provided with mounting holes, and are located at corresponding positions. A pair of stepped mounting holes are provided on the left and right guide plates 215 of the gun nozzle 21. The left rotating part 36 and the right rotating part 37 are respectively installed in the corresponding mounting holes, and the lower ends are embedded in the stepped mounting holes. The left fixing pin 63 and the right fixing pin 64 respectively pass through the left rotating part 36 and the right rotating part 37 and extend into the stepped mounting hole on the gun nozzle 21, so that the left clamp arm 32 and the right clamp arm 33 are rotatably mounted on the gun nozzle 21.

[0050] A block-shaped fixing member 38 is installed at one end of the gun nozzle 21 close to the gun body, and a slot 381 for the push rod 31 to pass through is provided below the fixing member 38. Figure 8 As shown, a stopper 382 protrudes from the middle portion of the fixing member 38, facing the side where the caliper arms are located, and is positioned between the ends of the left and right inclined mating sections. This acts as a barrier to the caliper arms, maintaining a gap between the rear ends of the two arms when the jaws are opened, thus preventing collision. The upper surface of the fixing member 38 is substantially coplanar with the upper surfaces of the left and right rotating portions 36 and 37. A pressure plate 39 is pressed against the upper surfaces of the fixing member 38, the left and right rotating portions 36 and 37. Space is formed between the pressure plate 39 and the left and right guide plates 215 of the muzzle 21 to accommodate the pair of caliper arms. The gap between the lower surface of the pressure plate 39 and the upper surfaces of the guide plates 215 is relatively small, meaning that this space is just enough for the caliper arms to be installed and rotated, and also provides a vertical limit on the rotation of the caliper arms, preventing them from sliding upward during rotation. This space effectively controls the longitudinal gap, preventing excessive gaps from causing nail collision. The rear end of the pressure plate 39 is fixed to the rear end of the gun nozzle 21 together with the fixing member 38 through the left bolt 65 and the right bolt 66, and the front end is installed above the left rotating part 36 and the right rotating part 37 through the left fixing pin 63 and the right fixing pin 64.

[0051] The execution device has a nail removal state and a nail pressing state during operation, so the execution device has a nail removal position 213 and a nail pressing position 214. Figure 6As shown, the gun case 22 is mounted at the nail removal position 213. The push rod 31 pushes the ring nail 1 from the nail removal position 213 to the nail pressing position 214. The jaws are located at the nail pressing position 214 to bend and press the ring nail 1. The gun muzzle 21 has a nail removal hole 212, which is located at the nail removal position 213. The gun case 22 is mounted below the nail removal hole 212. The nail pressing position 214 is located in front of the nail removal hole 212. The left jaw 321 and the right jaw 331 are located at the nail pressing position 214. The push rod 31 can retrieve the ring nail 1 at the nail removal position 213 and then push the ring nail 1 to the nail pressing position 214. The jaws can bend and press the ring nail 1 at the nail pressing position 214. The nail pressing position 214 also has an opening 216 for the object to be tied.

[0052] Specifically, if Figure 6 and Figure 9 As shown, the gun nozzle 21 includes a gun nozzle body, a separation plate 218 and a bottom baffle 219. The rear end of the gun nozzle body is fixedly mounted on the gun body, and the front end (i.e., the end away from the gun body) is sunken at the nail removal position 213 to form a groove 203. A separation plate 218 is fixed in the groove 203. The material hardness of the separation plate 218 is greater than the hardness of the gun nozzle 21 and has good wear resistance. The nail removal hole 212 is opened in the middle of the separation plate 218 and has a shape that is compatible with the buckle nail 1. Its size is only compatible with the buckle nail 1, and the buckle nail 1 can pass through here. A pair of bottom baffles 219 are also fixed on the front side of the separation plate 218. The bottom baffles 219 have a shape that is compatible with the location of the jaws at the front end of the clamp arm. A nail pressing position 214 is formed above the bottom baffles 219, and the above-mentioned opening 216 is formed between the pair of bottom baffles 219. The push rod 31 pushes the buckle nail 1 from above the nail removal hole 212 to above the bottom baffle 219, and then the jaws drive the buckle nail 1 to perform a closed nail pressing operation.

[0053] like Figure 9 and Figure 10As shown, the blocking assembly 70 includes a mounting component, a blocking member 72, a driving member and a mounting shaft 75. In this embodiment, the mounting component is a fixing seat 74, the driving member is a torsion spring 76, the fixing seat 74 is fixed above the gun nozzle 21 by a pair of bolts, and the blocking member 72 is movably set on the fixing seat 74. The fixing seat 74 is provided with an opening facing downward, and connecting lugs 741 are formed on both sides facing downward. The mounting shaft 75 is arranged horizontally through the two connecting lugs 741. The middle part of the blocking member 72 protrudes upward to form a connecting protrusion 724. The middle part of the connecting protrusion 724 has a through hole for the mounting shaft 75 to pass through. The connecting protrusion 724 is connected between the two connecting lugs 741 of the fixing seat 74 through the mounting shaft 75, so that the blocking member 72 can be rotated (swung) up and down with the mounting shaft 75 as the axis. The blocking member 72 is arranged between the nail removal position 213 and the nail pressing position 214. The front side of the blocking member 72 forms a right block-shaped blocking portion. The blocking portion is provided with a blocking surface 722 on the side facing the nail removal position 213. The bottom of the blocking member 72 is inclined to form a guiding inclined surface 721 facing the nail removal position. The torsion spring 76 is sleeved on the mounting shaft 75, and one end forms a sleeve portion 761, and the other end forms an abutment portion 762. The sleeve portion 761 is sleeved on the end of the blocking member 72 close to the blocking portion and acts on the blocking member portion; the abutment portion 762 is rod-shaped and acts on the inner wall of the fixed seat 74, so that the blocking portion can be maintained in a lower position, which is convenient for it to block the buckle nail when pressing the buckle nail. The end of the blocking member 72 away from the blocking portion is tilted upward, which is convenient for the push rod 31 to pass with the buckle nail 1. The two sides of the blocking portion, that is, the clamp arms facing the two sides are provided with side limiting surfaces 723 for abutting with the clamp arms, such as Figure 8 As shown, when the two pliers arms are closed, the protruding parts on the inner side of the jaws can be stuck on both sides of the blocking part, and the outer ends of the jaws are close to each other with a certain gap. The blocking part can limit the closing of the pliers arms, preventing the jaws from frequently closing too much and causing the outer ends of the jaws to collide, wear and fail.

[0054] The working state of the blocking member 72 of this embodiment is as follows: when the push rod 31 moves with the buckle nail 1 toward the nail pressing position 214, it moves to the blocking member 72, and the buckle nail 1 will gradually contact the guide inclined surface 721 and push the blocking part of the blocking member 72 to swing upward, so that the buckle nail 1 can move smoothly to the nail pressing position 214; when the buckle nail 1 moves to the nail pressing position 214, the push rod 31 retreats, and the blocking part swings downward under the action of the torsion spring 76, so that the blocking surface 722 on it can abut against the rear side of the buckle nail 1, which can prevent the closed end 3 from protruding backward due to pressure when pressing the nail, so that the annular nail after pressing the nail can be smoother.

[0055] Working process of this embodiment:

[0056] like Figure 11As shown, at this time, the buckle nail 1 is pushed to the nail pressing position 214 by the pushing end 312 of the push rod 31, and the pushing end 312 is located at the position where the blocking member 72 is clamped. With this position as the initial position, when pressing the nail, the opening 216 is aligned with the object to be tied, and then the push rod 31 moves backward (towards the direction where the gun body is located). The left clamp arm 32 and the right clamp arm 33 initially contact the left roller 34 and the right roller 35 with the parallel matching section 3221. During this stage, the left clamp arm 32 and the right clamp arm 33 The left roller 34 then contacts the inclined fitting section 3222 on the left arm 32, causing the left arm 32 to rotate, causing the left jaw 321 to buckle inwards, applying force to the buckle nail 1, thereby pressing the buckle nail until the roller moves to the right. Figure 8 Position, complete the nail pressing, at this time, the protruding parts on the inner side of the jaws are just stuck on both sides of the blocking part.

[0057] After completing the nail pressing, the push rod 31 will move forward again. At this time, the front ends of the left clamp arm 32 and the right clamp arm 33 will open, and the buckle nail that has completed the previous nail pressing will be released; when performing the next nail pressing action, the pushing end 312 will continue to move forward, pushing the next buckle nail located at the nail removal position 213 to the nail pressing position 214 and returning it to the initial position for the next nail pressing.

[0058] like Figure 12-14 As shown, the nail magazine 22 includes an inner clip 23, an outer clip 24 and a fixing member 25. The cross-section of the outer clip 24 is basically C-shaped and at least partially surrounds the inner clip 23. The inner clip 23 is hollow and cylindrical, and a nail storage gap 26 for storing the retaining ring nails 1 is formed between the inner clip 23 and the outer clip 24. The nail storage gap 26 has a shape that is compatible with the C-shaped nail, so that several retaining ring nails 1 can be vertically stacked in the nail storage gap 26. The fixing member 25 passes through the inner clip 23 and the outer clip 24 from the bottom to fix the two to each other.

[0059] A nail feeding assembly 27 for transporting the buckle nail 1 toward the side where the jaws are located is installed on the inner clamp 23. The nail feeding assembly 27 has a nail feeding member 271 and an elastic member 272. The nail feeding member 271 includes a main body 2711, a nail feeding end 2712 and a fixed end 2713. The nail feeding end 2712 has a shape that matches the buckle nail 1 and is used to be positioned under the buckle nail 1 located at the bottom; the fixed end 2713 is formed by bending one end of the main body 2711 away from the nail feeding end 2712, and is used to be installed on the elastic member 272, so that under the elastic action of the elastic member 272, the buckle nail 1 can always have a tendency to move toward the side where the jaws are located.

[0060] Since the inner clip 23 is hollow, the elastic member 272 is a force spring, which can be installed inside the inner clip 23. The inner clip 23 has a long guide groove 231 along the length direction on the side facing the gun body 10. The fixed end 2713 can pass through the guide groove 231 and be clamped on the force spring. The bottom fixing member 25 is also clamped with a spring fixing member 2721, and the bottom end of the force spring is sleeved on the spring fixing member 2721. When in use, Figure 12 As shown, multiple buckle nails 1 are stacked above the nail feeding end 2712. Under the gravity of the buckle nails 1, the force spring is compressed so that the force spring has a certain elastic force. When the first buckle nail 1 at the top is taken away by the push rod 31 and sent out, the second buckle nail 1 will be pushed to the top under the push rod 31 under the elastic force of the force spring, waiting to be taken away next time. In addition, see Figure 12 The outer clip 23 of the nail magazine 22 is located on the outer circle of the snap ring nail 1. When the snap ring nail 1 is stacked in the nail storage gap 26, the snap ring nail 1 at the top is higher than the top of the inner clip 23 and the outer clip 24 under the action of the nail feeding assembly 27. Figure 6 As shown, the top of the outer clip 23 is exactly flush with the groove 203 at the front end of the gun nozzle 21. The buckle nail 1 that is higher than the top part of the outer clip 23 can be inserted into the nail removal hole 212 of the separation plate 218. The outer clip 23 will be blocked by the separation plate 218 at the lower part of the separation plate 218, thereby ensuring the accuracy of nail removal.

[0061] like Figure 3 and Figure 15As shown, the driving device 40 has a mounting frame 46, a guide component 41, an energy storage component 42, a driving seat 43 and a power component 45. The mounting frame 46 has a first fixed seat 461 and a second fixed seat 462 arranged at both ends and two left and right connecting plates connecting the two fixed seats. The first fixed seat 461 and the second fixed seat 462 are both fixed on the front cover 11 and the rear cover 12. The guide component 41 is a guide rod mounted on the first fixed seat 461 and the second fixed seat 462. The energy storage component 42 and the driving seat 43 are both movably arranged on the guide rod and located between the first fixed seat 461 and the second fixed seat 462. The energy storage component 42 is an energy storage spring. A spring mounting seat 463 is provided on the first fixed seat 461, and a drive seat washer 431 is provided on the drive seat 43. One end of the energy storage spring is mounted on the spring mounting seat 463, and the other end is mounted on the drive seat washer 431. The push rod 31 is also fixed to the drive seat 43. When the drive seat 43 moves toward the side where the energy storage spring is located, driven by the power component 45, the energy storage spring is compressed, thereby accumulating energy. At the same time, the drive seat 43 moves toward the side where the energy storage spring is located, and the roller on the push rod 31 rolls along the clamp arm, driving the left jaw 321 and the right jaw 331 to move closer together and close together to press the nail. When the drive seat 43 is not affected by the power component 45, the accumulated elastic force of the energy storage spring causes the drive seat 43 to move toward the side where the actuator 30 is located, driving the push rod 31 toward the side where the nail magazine is located, and pushing the retaining nail 1 from the material removal position to the nail pressing position.

[0062] In this embodiment, if Figure 15 As shown, the energy storage component 42 comprises two energy storage springs, one inside the other, placed together. In practice, since the primary source of power for the pressure pin is the power component, while the energy storage spring acts as a propulsion mechanism, the requirements for the energy storage spring are relatively low, so a single energy storage spring can be used. Alternatively, two energy storage springs can be installed side by side in parallel, or in series along a guide rod. A buffer is also mounted on the side of the second fixed seat 462 facing the drive seat 43 to cushion the movement of the drive seat 43 toward the actuator.

[0063] In this embodiment, the fixing portion 311 of the push rod 31 is fixed on the driving seat 43 and can move under the action of the driving seat. Figure 17 As shown, a mounting surface is formed above the driving seat 43 , and the fixing portion 311 is fixed on the mounting surface by a fixing pin.

[0064] like Figure 16As shown, the power component 45 includes a motor 451, a reducer 452 and a power driving component 453. The motor 451 has a motor shaft, the reducer 452 is installed on the motor shaft and has an output end, the power driving component 453 is installed on the output end and has a push wheel for contacting the driving seat 43. The motor 451 drives the power driving component 453 to rotate, thereby pushing the driving seat 43 to move the driving seat 43 toward the side where the energy storage component 42 is located, so that the energy storage component 42 stores energy. Among them, the power driving member 453 has a main body part 4532, the middle part of the main body part 4532 is a circle, and two protruding parts 4533 are formed on the circumference of the circle, and a push wheel (a first push wheel 454 and a second push wheel 455) are respectively installed on the two protruding parts 4533. A push plate 432 is provided on the side of the driving seat 43 facing the driving member 453. The push plate 432 has a first pushing end 4321 and a second pushing end 4322, wherein the first pushing end 4321 cooperates with the first pushing wheel 454, and the second pushing end 4322 cooperates with the second pushing wheel 455. During the rotation of the driving member 453, the first pushing wheel 454 and the second pushing wheel 455 respectively act on the first pushing end 4321 and the second pushing end 4322 to push the driving seat 34.

[0065] <Example 2>

[0066] This embodiment is substantially the same as the first embodiment described above, except that, whereas in the first embodiment, the energy storage spring is mounted between the first fixed seat and the driving seat, in this embodiment, the energy storage spring is mounted between the second fixed seat and the driving seat. A power component drives the driving seat toward the second fixed seat. At this point, the push rod moves forward, pushing the retaining nail 1 and causing the front end of the clamp arm to open, while the energy storage spring accumulates energy. The elastic force of the energy storage spring then pushes the driving seat toward the first fixed seat. At this point, the push rod moves backward, driving the front end of the clamp arm to close, thereby pressing the nail. Therefore, in this embodiment, the energy storage spring is the primary source of power for pressing the nail.

[0067] <Example 3>

[0068] This embodiment is based on the above embodiment 1. Figure 17 As shown, a spacer 49 is provided between the guide rod (i.e., the guide member 41) and the drive seat 43 and the second fixed seat 462. The length of the spacer 49 is set according to the length of the guide rod and the travel of the push rod 31. Adding the spacer 49 to Example 1 can reduce the travel of the drive seat, thereby reducing the travel of the push rod 31. The length of the travel can be determined according to actual needs.

[0069] <Example 4>

[0070] This embodiment is basically the same as the above-mentioned embodiments 1-3, except that the driving device of this embodiment is a pneumatic driving device, that is, the power components in the above-mentioned embodiments 1-3 are replaced with pneumatic components, such as cylinders, or the energy storage spring is replaced with an air cavity, and the gas in the air cavity is compressed by the movement of the driving seat to achieve energy storage, and then the driving seat is pushed out by relying on air pressure to achieve driving.

[0071] The above embodiments are only used to illustrate specific implementation methods of the present invention, and the present invention is not limited to the description scope of the above embodiments.
