[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 ring nails mainly include manual and pneumatic types. The manual type requires manual pressing of the clamp arm to clamp the nail, which is inefficient and laborious. Although the pneumatic type is more labor-saving and efficient than the manual type, the pneumatic type usually requires an air cavity or an external air pressure supply device to be set in the gun body, and the sealing of the air cavity must be ensured. The structure is complex, inconvenient to carry and the maintenance cost is high. Summary of the Invention

[0044] <Example 1>

[0045] This embodiment provides an electric snap ring nail gun for bending snap ring nails. The snap ring nail 1 of this embodiment takes a C-shaped nail 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 buckle nail gun is shown, which includes a gun body 10 and a drive actuator, a power supply unit and a control unit, wherein the drive actuator includes a gun nozzle mechanism 20, an actuator 30 and a drive mechanism 40, the gun nozzle mechanism 20 is installed at the front end of the gun body 10, and has a gun nozzle 21, a nail magazine 22 for storing buckle nails 1 and a blocking assembly 70, the actuator 30 is movably arranged on the gun nozzle 21, and is used to act on the buckle nail 1, and the drive mechanism 40 is installed in the gun body 10, and is used to drive the actuator 30 to work.

[0046] like Figure 2 As shown, the gun body 10 is formed by a front cover 11 and a rear cover 12, which are arranged in front and back and interlock with each other and fixed by screws. The interior forms a mounting cavity for mounting the drive mechanism 40. The gun body 10 not only accommodates the drive mechanism 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 in 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 mechanism.

[0047] 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 buckle nail 1, and a blocking assembly 70 for abutting against the rear side of the closed end 3 of the buckle nail 1 when the buckle nail 1 is pressed. The gun nozzle 21 is installed between the nail magazine 22 and the gun body 10, and the top of the nail magazine 22 is basically aligned with the bottom of the gun nozzle 21. An actuator 30 is installed above the gun nozzle 21, as shown in FIG. Figure 4 As shown, the actuator 30 has a connecting member 31, a pair of clamp arms (left clamp arm 32, right clamp arm 33), a pair of connecting rods (left connecting rod 34, right connecting rod 35) and a guide member 36, wherein a pair of jaws (left jaw 321, right jaw 331) are opened on the front side of the pair of clamp arms, the left jaw 321 and the right jaw 331 are arranged opposite to each other, and have a shape adapted to the buckle nail 1. When working, the left jaw 321 and the right jaw 331 act on the left and right sides of the open end 2 of the buckle nail 1 respectively, and the two jaws approach each other to cause the open end 2 to bend and gradually close.

[0048] like Figure 3 and Figure 5 As shown, the driving mechanism 40 has a mounting frame 46, a guide component 41, an energy storage component 42, a driving seat 43, a pushing component 44 and an electric component 45. The mounting frame 46 has a first fixing seat 461 and a second fixing seat 462 provided at both ends and two left and right connecting plates connecting the two fixing seats. The first fixing seat 461 and the second fixing 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 fixing seat 461 and the second fixing seat 462. The energy storage component 42 The drive seat 43 and the first fixed seat 461 are both movably mounted on the guide rod and positioned between the second fixed seat 462. The energy storage component 42 is an energy storage spring. The first fixed seat 461 is provided with a spring mounting seat 463, and the drive seat 43 is provided with a drive seat washer 431. 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. When the drive seat 43 moves toward the energy storage spring under the influence of the electric component 45, the energy storage spring is compressed, thereby accumulating energy. When the drive seat 43 is not affected by the electric component 45, the accumulated elastic force of the energy storage spring causes the drive seat 43 to move toward the actuator 30. The push component 44 pushes the connector 31 toward the nail magazine, forcing the left and right jaws 321 and 331 to move closer and close. A buffer member 47 is further installed on the side of the second fixing seat 462 facing the driving seat 43 to provide a buffer for the driving seat 43 when it moves toward the side where the actuator is located.

[0049] like Figure 5As shown, in this embodiment, the energy storage spring adopts a double spring, which is an inner and outer double spring with an inner and outer spring joined together. In actual situations, a single energy storage spring can also be used, or two energy storage springs can be installed side by side to form a left and right double spring in parallel, or two energy storage springs can be installed in series along a guide rod to form a front and rear double spring.

[0050] In this embodiment, the pushing member 44 is a push rod, one end of which is fixed to the driving seat 43 and can move under the action of the driving seat, and the other end extends out of the second fixing seat 462 and is connected to the connecting member 31. As shown in the figure, a mounting surface is formed above the driving seat 43, and one end of the push rod is fixed to the mounting surface by a fixing pin. Figure 6 As shown, the second fixing seat 462 has adjacent push rod limiting portion 4621 and gun nozzle fixing portion 4622. The push rod limiting portion 4621 is higher than the gun nozzle fixing portion 4622. The push rod limiting portion 4621 is provided with an escape groove 464 for the other end of the push rod to pass through. The gun nozzle 21 is fixedly mounted on the gun nozzle fixing portion 4622. A through groove 211 is provided in the middle portion of the gun nozzle 21 along its length. The escape groove 464 is aligned with the through groove 211, allowing the other end of the push rod to pass through the escape groove 464 and extend above the through groove 211 to connect with the connecting member 31. At the same time, the second fixing seat 462 has limiting protrusions 465 on both sides of the escape groove 464. These two limiting protrusions 465 cooperate with the escape groove 464 to guide the movement of the push rod on the one hand, and to limit the push rod to the left and right on the other hand, preventing the push rod from deviating from the moving direction during movement.

[0051] In addition, the bottom of the avoidance groove 464 is higher than the bottom of the through groove 211, so that the push rod limiting portion 4621 forms a limiting surface 467 on the side facing the through groove 211, which is used to block the connecting member 31 and limit the stroke of the connecting member 31. Figure 6 As shown, the second fixing seat 462 is located on one side of the avoidance groove 464 and is formed with a mounting platform 466, and one end of the gun nozzle 21 is fixed on the mounting platform 466. Figure 7 As described, the connecting member 31 is in the shape of an "I" character, having a first connecting end 311 and a second connecting end 312. The outer end of the push rod is connected to the first connecting end 311 through a connecting pin 61, and one end of the left connecting rod 34 and the right connecting rod 35 is connected to the second connecting end 312 through a connecting pin 62. When the push rod moves following the drive seat 43, it can drive the connecting member 31 to move along the through slot 211.

[0052] like Figure 5 and Figure 8As shown, the electric component 45 includes a motor 451, a reducer 452 and a driving member 453. The motor 451 has a motor shaft, the reducer 452 is installed on the motor shaft and has an output end, the driving member 453 is installed on the output end and has a push wheel for contacting the driving seat 43. The motor 451 drives the driving member 453 to rotate, thereby pushing the driving seat 43 to move the driving seat 43 toward the side where the energy storage component 42 (energy storage spring) is located, so that the energy storage spring is compressed to store energy. Among them, the 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.

[0053] like Figure 9 As shown, a pair of planar guide plates 215 extending along the length direction are formed on both sides of the through slot 211, and the connecting member 31 and the guide member 36 are moved and arranged on the through slot 211 in sequence, and the guide member 36 is located in front of the connecting member 31 (on the side away from the gun body 10), and the left clamp arm 32 and the right clamp arm 33 are respectively rotatably arranged on the left and right sides of the guide member 36, and the left clamp arm 32 and the right clamp arm 33 can move along the left and right guide plates 215, and one end of the left connecting rod 34 and the right connecting rod 35 are installed on the side of the connecting member 31 close to the guide member 36, and the left connecting rod 34, the right connecting rod 35 and the connecting member 31 are connected to form a Y-shaped structure, and the other ends of the left connecting rod 34 and the right connecting rod 35 are respectively connected to the left clamp arm 32 and the right clamp arm 33. The guide member 36 has a connecting pin 66, and the middle parts of the left plier arm 32 and the right plier arm 33 respectively protrude toward each other to form connecting plates. The connecting pin 66 passes through the guide member 36 and the connecting plates on the two plier arms to connect the three together. The two plier arms can move together with the guide member 36. At the same time, the two plier arms can also rotate with the connecting pin 66 as the axis to achieve opening and closing.

[0054] like Figure 10As shown, the through slot 211, located on the side of the guide member 36 facing away from the connector 31, defines a nail-out hole 212 with a contour matching the shape of the snap-on nail 1. This nail-out hole 212 corresponds to the nail magazine 22. The pair of clamp arms also have a nail-removal position 213 and a nail-pressing position 214. The nail-out hole 212 is located at the nail-removal position 213, while the nail-pressing position 214 is located in front of the nail-out hole 212, i.e., at the front end of the muzzle 21. When the clamp arms are in the nail-removal position (the jaws align with the nail-removal position 213), the jaws can retrieve the snap-on nail 1. When the jaws follow the clamp arms to the nail-pressing position 214 (the jaws align with the nail-removal position 214), the jaws bend the snap-on nail 1 and press it. The muzzle 21 also has an opening 216 at the nail-pressing position 214 for access to objects to be bound.

[0055] Specifically, when the nail is removed at position 213, Figure 12 As shown, the left jaw 321 and the right jaw 331 are located above the nail hole 212 and the exit of the nail magazine 22 and are aligned for obtaining the buckle nail 1. Figure 13 As shown, when the connecting member 31 drives the left and right clamp arms 32 and 33 forward to the nail pressing position 214 via the left connecting rod 34, the right connecting rod 35, and the guide member 36, the left jaw 321 and the right jaw 331 are located above the front end of the gun nozzle 21. At this time, the left and right clamp arms 32 and 33 can rotate so that the left and right jaws 321 and 331 approach each other, thereby bending and gradually closing the ring nail 1. As the left and right clamp arms 32 and 33 move forward, the ring nail 1 is moved forward together with the left and right jaws 321 and 331 until it reaches the nail pressing position 214.

[0056] like Figure 10 and Figure 11 As shown, the blocking assembly 70 is located between the nail removal position 213 and the nail pressing position 214, and includes a mounting component 71, a blocking component 72 and an elastic component 73. The mounting component 71 is plate-shaped and fixed above the gun nozzle 21. The blocking component 72 is movably arranged on the mounting component 71 and is located between the nail removal position (nail removal position 213) and the nail pressing position (nail pressing position 214). The elastic component 73 is a spring, which is installed between the blocking component 72 and the mounting component 71 and is used to reset the blocking component 72. The blocking component 72 is provided with a guide slope 721 on the side facing the nail removal position (nail removal position 213). When the pliers arm moves with the retaining ring nail 1 toward the nail pressing position 214, it moves to the blocking component 72. The retaining ring nail 1 contacts the guide slope 721 and pushes the blocking component 72 to move upward, so that the retaining ring nail 1 can smoothly cross the position of the blocking component 72 and move to the nail pressing position 214. The blocking member 72 is provided with a blocking surface 722 on the side facing the nail pressing position (nail removal position 213) for abutting against the closed end 3 of the buckle nail 1. When the buckle nail 1 is pressed by the jaws at the nail pressing position 214, the blocking surface 722 abuts against the closed end 3 (such as Figure 14 As shown), the closed end 3 can be prevented from protruding backward due to pressure, so that the annular nail can be smoother after the nail is pressed.

[0057] In this embodiment, if Figure 10 As shown, the mounting component 71 is formed by combining two plates, namely an upper plate 711 and a lower plate 712. The middle portion of the upper plate 711 protrudes upward to form a mounting block 713, which is hollow inside. The lower plate 712 has a mounting hole corresponding to the location of the mounting block 713. The upper end of the blocking member 72 is formed with a step structure, and the blocking member 72 is installed in the mounting hole through this step structure. The mounting block 713 is located above the blocking member 72, and the spring is installed inside the mounting block 713. To avoid interference with the mounting component 71 during the movement of the guide member 36, an avoidance opening 714 with a shape that matches the guide member 36 is opened on the side of the mounting component 71 facing the guide member 36.

[0058] The bottom of the lower plate 712 is flat, and a space is formed between it and the guide plate 215 of the gun nozzle 21 for the tongs arm to pass through. The gaps between the upper and lower surfaces of the tongs arm and the flat bottom surface of the lower plate 712 and the upper surface of the guide plate 215 of the gun nozzle 21, respectively, are close to zero. In other words, this space is just wide enough for the tongs arm to pass through, limiting the movement of the tongs arm up and down, preventing the tongs arm from sliding upward during movement. In other words, this space effectively controls the longitudinal gap, preventing excessive gap from causing nail collision.

[0059] In this embodiment, the guide member 36 and the connecting member 31 are both block-shaped, and the through slot 211 is a dovetail slot. Accordingly, the bottoms of the guide member 36 and the connecting member 31 have shapes that match the dovetail slot. The dovetail slot design can limit the guide member 36 and the connecting member 31 in the longitudinal direction to prevent them from falling.

[0060] like Figure 14 and Figure 15 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.

[0061] like Figure 14-17As shown, 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, and 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 is compatible with the buckle nail 1 and is used to be positioned below 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.

[0062] 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 15 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 clamp arm and sent out, the second buckle nail 1 will be pushed to the top under the elastic force of the force spring, waiting to be taken away next time. In addition, see Figure 15 When the retaining ring nail 1 is stacked in the nail storage gap 26, the retaining ring nail 1 at the top is higher than the top of the inner clamp 23 and the outer clamp 24 under the action of the nail feeding assembly 27, which makes it convenient for the clamp arm to take away the retaining ring nail 1 and carry it for transfer.

[0063] Since the clamp arm needs to move forward with the snap ring nail 1, in order to avoid being blocked by the nail feeding member 271 during the movement after the last snap ring nail 1 is taken away, the clamp arm has an inclined extrusion surface 322 at the rear side of the jaw for pressing the nail feeding member 271 downward. Figure 11 (Take the left clamp arm 32 as an example).

[0064] like Figure 14As shown, the nail magazine 22 is fixed to the gun nozzle 21 through a fixing assembly, which has an L-shaped connecting piece 28, a first fixing pin 63, a second fixing pin 64 and a fixing plate 65. The L-shaped connecting piece 28 contains a first connecting piece 281 and a second connecting piece 282 arranged perpendicular to each other, wherein the first fixing pin 63 and the second fixing pin 64 can be selected from bolts or screws. The first fixing pin 63 passes through the gun nozzle 21 and the first connecting piece 281 in sequence and is combined with a fixing nut to fix the two. The second fixing pin 64 passes through the outer clamp 24, the second connecting piece 282, and the fixing plate 65 in sequence and is combined with a fixing nut to fix the three to achieve the installation and fixation of the nail magazine 22 and the gun nozzle 21.

[0065] <Example 2>

[0066] This embodiment is basically the same as the above-mentioned embodiment 1, except that, in the above-mentioned embodiment 1, the inner end of the pushing member 44 (push rod) is directly mounted on the driving seat 43, while in this embodiment, the pushing member 44 is not mounted on the driving seat 43. Specifically, Figure 18 As shown, the driving mechanism 40 of this embodiment also has a pushing seat 48, which is movably arranged on the guide rod (i.e., the guide component 41) and is located between the driving seat 43 and the second fixed seat 462. A return spring 481 is provided between the pushing seat 48 and the second fixed seat 462. One end of the pushing component 44 is installed on the pushing seat 48, and the other end extends from the second fixed seat 462 and is installed on the connecting member 31. The driving seat 43 hits and pushes the pushing seat 48 to drive the pushing component 44 to move.

[0067] <Example 3>

[0068] This embodiment is based on the above embodiment 1. Figure 19 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 pushing member 44. Adding the spacer 49 to Example 1 can reduce the travel of the drive seat, thereby reducing the travel of the pushing member 44. The length of the travel can be determined according to actual needs.

[0069] 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.
