Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Referring now to fig. 1 and 2, a nail gun 100 in accordance with an embodiment of the first aspect of the present invention will be described.

As shown in fig. 1 and 2, according to a nail gun 100 of an embodiment of the present invention, the nail gun 100 is used to fire a fastening nail 101, and the nail gun 100 includes a housing 1, a pushing assembly 2, a plurality of capacitors 3, and a power source 4.

Be equipped with circuit board 5 in the casing 1, casing 1 has and penetrates nail mouth 120, and the fastener 101 can be followed and penetrated nail mouth 120 and ejected, and promotion subassembly 2 includes electro-magnet 21, and electro-magnet 21 locates in casing 1 and electro-magnet 21 is changeable between first state and second state, and when electro-magnet 21 is in when the first state, electro-magnet 21 is kept away from fastener 101 with fastener 101 interval setting, and when electro-magnet 21 is in the second state, electro-magnet 21 and fastener 101 contact are in order to produce the impact force to fastener 101, and when electro-magnet 21 circular telegram, electro-magnet 21 switches to the second state from the first state in order to penetrate nail 101 from penetrating nail mouth 120 with fastener 21. A plurality of capacitors 3 are provided in the case 1, each capacitor 3 is electrically connected to the circuit board 5, the plurality of capacitors 3 switchably supply power to the electromagnet 21 through the circuit board 5, the power source 4 is provided in the case 1 and the power source 4 is electrically connected to each capacitor 3 to charge each capacitor 3.

For example, as shown in fig. 1 and 2, the power source 4 is electrically connected to each capacitor 3, so that a charging circuit may be formed between the power source 4 and each capacitor 3, so that the power source 4 may independently charge each capacitor 3, i.e., the plurality of capacitors 3 may be independently charged without interfering with each other, i.e., when one of the plurality of capacitors 3 is charged by the power source 4, the charging of the remaining capacitors 3 of the plurality of capacitors 3 by the power source 4 is not affected.

The circuit board 5 can be fixedly installed in the housing 1, so that the housing 1 can play a role of protecting the circuit board 5; each of the plurality of capacitors 3, which has completed charging, may supply power to the electromagnet 21 through the circuit board 5, so that electromagnet 21 can be switched from the first state to the second state, i.e. before capacitor 3 supplies electromagnet 21, electromagnet 21 can be in the first state to be spaced from fastening pin 101, in which case there may be no force between electromagnet 21 and fastening pin 101, and when capacitor 3 supplies electromagnet 21, the electromagnet 21 can be switched to the second state quickly to generate impact force on the fastening nail 101, the electromagnet 21 can eject the fastening nail 101 from the inside of the housing 1 to the outside of the housing 1 through the nail ejection opening 120, at this time, the capacitor 3 supplying power to the electromagnet 21 completes discharging, when the nail gun 100 is required to eject the fastening nail 101 again, the charged capacitor 3 supplies power to the electromagnet 21 through the circuit board 5 to eject the fastening nail 101. That is, the nail gun 100 requires one capacitor 3 to supply power to the electromagnet 21 every time the fastener 101 is fired.

The plurality of capacitors 3 switchably supply power to the electromagnet 21 through the circuit board 5, that is, one capacitor 3 is required to supply power to the electromagnet 21 each time the nail gun 100 ejects the fastening nail 101, and two capacitors 3 supplying power to the electromagnet 21 are not the same capacitor 3 in the process that the nail gun 100 ejects the fastening nail 101 two times adjacently, so that the capacitor 3 which is not charged among the remaining capacitors 3 among the plurality of capacitors 3 can be charged in the process that one of the plurality of capacitors 3 supplies power to the electromagnet 21 to complete nail ejection, so that the capacitor 3 which is not charged among the remaining capacitors 3 among the plurality of capacitors 3 can be charged in the process that one of the capacitors 3 is discharged during nail ejection of the nail gun 100 to shorten the time interval between two adjacent nail ejections, which is about 2s compared to the time interval between two adjacent nail ejections in the conventional art, the present application of the nail gun 100 provides better work efficiency and facilitates rapid and continuous nail firing of the nail gun 100. Each capacitor 3 may be electrically connected to the circuit board 5, and the electromagnet 21 may be electrically connected to the circuit board 5.

It is to be understood that "the capacitor 3 of the plurality of capacitors 3 which is not charged completely may be charged during the discharge of the one of the capacitors 3" may include the capacitor 3 of the plurality of capacitors 3 which is not charged completely being charged during the discharge of the one of the capacitors 3, and may also include the capacitor 3 of the plurality of capacitors 3 which is not charged completely being charged and not being charged completely during the discharge of the one of the capacitors 3.

For example, when there are two capacitors 3, the two capacitors 3 switchably supply the electromagnet 21 via the circuit board 5, that is, the two capacitors 3 sequentially supply the electromagnet 21 by turns via the circuit board 5. Specifically, the two capacitors 3 may be a first capacitor 31 and a second capacitor 32, respectively, and before the nail gun 100 is used, the first capacitor 31 and the second capacitor 32 may both complete charging, first the first capacitor 31 supplies power to the electromagnet 21 through the circuit board 5, so that the electromagnet 21 is switched from the first state to the second state to fire the fastening nail 101, thereby completing the first nail firing of the nail gun 100; when the nail gun 100 needs to be fired again, the second capacitor 32 can supply power to the electromagnet 21 through the circuit board 5, and the electromagnet 21 is also switched from the first state to the second state to fire the fastening nail 101, so as to complete the second nail firing of the nail gun 100, during the second nail firing, the power source 4 can charge the first capacitor 31, so that when the nail gun 100 needs to be fired for the third time, the charged first capacitor 31 supplies power to the electromagnet 21 through the circuit board 5 again to realize the nail firing, and the process is repeated.

For another example, when there are three capacitors 3, the three capacitors 3 switchably supply the electromagnet 21 through the circuit board 5, that is, the three capacitors 3 may switchably supply the electromagnet 21 through the circuit board 5 in a certain order. For example, three capacitors 3 may be sequentially and alternately used as the electromagnets 21 through the circuit board 5, but the invention is not limited thereto, and it is only required to ensure that two capacitors 3 for supplying power to the electromagnets 21 are not the same capacitor 3 in two adjacent nail shots during the nail shooting process of the nail gun 100, and that the capacitor 3 with completed discharge is charged by the power supply 4 during the nail shooting process of one capacitor 3 for supplying power to the electromagnets 21.

For another example, when four capacitors 3 are provided, four capacitors 3 switchably supply power to the electromagnet 21 through the circuit board 5, that is, four capacitors 3 switchably supply power to the electromagnet 21 through the circuit board 5 in a certain order. For example, four capacitors 3 may be sequentially and alternately used as the electromagnets 21 through the circuit board 5, but the invention is not limited thereto, and it is only required to ensure that two capacitors 3 for supplying power to the electromagnets 21 are not the same capacitor 3 in two adjacent nail shots during the nail shooting process of the nail gun 100, and that the capacitor 3 with completed discharge is charged by the power supply 4 during the nail shooting process of one capacitor 3 for supplying power to the electromagnets 21.

It is understood that the number of the capacitors 3 may be five or more. In the description of the present invention, "a plurality" means two or more.

According to the nail gun 100 of the embodiment of the invention, the plurality of capacitors 3 are arranged in the shell 1 of the nail gun 100, so that each capacitor 3 can be charged by the power supply 4, and the plurality of capacitors 3 supply power to the electromagnet 21 in a switching manner through the circuit board 5, so that the two capacitors 3 supplying power to the electromagnet 21 are not the same capacitor 3 in the process of two adjacent times of emission of fastening nails 101 by the nail gun 100, the time interval of two adjacent times of emission of the nail gun 100 is shortened, the working efficiency of the nail gun 100 is effectively improved, and the nail gun 100 is convenient to realize rapid and continuous nail emission.

In some embodiments of the present invention, the pushing assembly 2 further comprises a reset member 22, the reset member 22 providing a biasing force to the electromagnet 21, the biasing force being capable of switching the electromagnet 21 from the second state to the first state; it is understood that reset element 22 applies a force to electromagnet 21 that causes electromagnet 21 to switch from the second state to the first state, or that reset element 22 is connected to electromagnet 21 and reset element 22 always drives electromagnet 21 to switch to the first state; in other words, the biasing force or the force may cause the electromagnet 21 to have a tendency to switch to the first state. For example, as shown in fig. 1 and fig. 2, the electromagnet 21 may include a solenoid 211 and an iron core 212, the iron core 212 may be movably disposed in the solenoid 211, when the solenoid 211 is energized, the iron core 212 may be moved forward under the action of the magnetic field of the solenoid 211 to switch the electromagnet 21 from the first state to the second state, the iron core 212 may push the fastening pin 101 out of the nail ejecting opening 120 rapidly during the moving process, so that the fastening pin 101 is ejected from the nail ejecting opening 120, and when the iron core 212 moves forward, a force may be applied to the reset element 22, so that the shape of the reset element 22 changes; in order to restore the original shape of the reset member 22, the reset member 22 applies an acting force to the iron core 212, so that the iron core 212 moves in the opposite direction under the action of the acting force applied to the iron core 212 by the reset member 22, the electromagnet 21 is switched from the second state to the first state, the reset of the iron core 212 is realized, and the state of the electromagnet 21 is restored to prepare for nail shooting again, that is, the reset member 22 applies an acting force to the electromagnet 21, and the acting force makes the electromagnet 21 have a tendency to switch towards the first state. Wherein the restoring member 22 may be an elastic member, such as a spring.

It is understood that "reset member 22 always drives electromagnet 21 to switch to the first state" may refer to the tendency of reset member 22 to generate a driving force on electromagnet 21 such that electromagnet 21 has a switch to the first state.

When the restoring element 22 is a spring, the restoring element 22 can be pressed in the process that the iron core 212 moves in the forward direction, so that when the electromagnet 21 is in the second state, the restoring element 22 is in a compressed state, and the iron core 212 moves in the reverse direction under the action of the elastic force exerted by the restoring element 22, so that the electromagnet 21 is switched from the second state to the first state; alternatively, the restoring member 22 may be stretched during the forward movement of the iron core 212, so that when the electromagnet 21 is in the second state, the restoring member 22 may be in a stretched state, and the iron core 212 may also move in the reverse direction under the elastic force applied by the restoring member 22, so that the electromagnet 21 is switched from the second state to the first state.

Here, it should be noted that "forward" and "reverse" are relative concepts, and do not refer to a certain direction.

Further, the electromagnet 21 includes a solenoid 211, an iron core 212, and a striker 213, the iron core 212 is movably disposed in the solenoid 211, the striker 213 is connected to the iron core 212, when the solenoid 211 is energized, the iron core 212 pushes one fastening pin 101 to be ejected from the nail ejection opening 120, and the reset piece 22 applies an elastic force to at least one of the iron core 212 and the striker 213 in a first direction (for example, a direction pointing to B in fig. 1), which is an opposite direction to a moving direction of the iron core 212 when the electromagnet 21 is switched from the first state to the second state. For example, in the example of fig. 1 and 2, the striker 213 may be fixedly connected to the core 212, at this time, the core 212 may drive the striker 213 to move during the movement of the core 212, and at the same time, the striker 213 may drive the core 212 to move during the movement of the core 212, and the striker 213 may be disposed on a side of the core 212 close to the nail ejection opening 120, that is, an interval between the striker 213 and the nail ejection opening 120 is smaller than an interval between the core 212 and the nail ejection opening 120, in other words, the core 212 may push one fastening nail 101 to be ejected from the nail ejection opening 120 through the striker 213, and due to the good design flexibility of the striker 213, the cross-sectional shape of the striker 213 may better match the shape of the fastening nail 101, so that the striker 213 may effectively, stably and quickly push the fastening nail 101 to be ejected, and the structure of the core 212 is simplified; during the movement of the plunger 212 and the striker 213, the reset element 22 may directly apply an elastic force to the striker 213 opposite to the movement direction of the striker 213, so that the striker 213 may bring the plunger 212 back to the original position under the action of the elastic force after completing the pushing out of the fastening pin 101, so as to prepare for the next nail shooting.

It can be understood that, during the movement of the iron core 212 and the striker 213, the reset element 22 may also directly apply an elastic force to the iron core 212 opposite to the movement direction of the iron core 212, so that after the striker 213 finishes pushing out the fastening pin 101, the iron core 212 may bring the striker 213 back to the original position together under the action of the elastic force; alternatively, the restoring member 22 may directly apply an elastic force to the core 212 and the striker 213 simultaneously in a direction opposite to the movement direction of the core 212 during the movement of the core 212 and the striker 213.

Of course, when the electromagnet 21 includes the solenoid 211, the plunger 212 and the striker 213, the striker 213 and the plunger 212 may not be connected to each other, that is, there is no direct or indirect connection between the striker 213 and the plunger 212, at this time, the plunger 212 may still push the fastening nail 101 to eject from the nail ejection opening 120 through the striker 213, and the reset element 22 may directly apply an elastic force to the striker 213 opposite to the movement direction of the striker 213, thereby ensuring the simultaneous return of the plunger 212 and the striker 213.

It is understood that the biasing force applied by the restoring member 22 to the electromagnet 21 may be an elastic force, or may be other types of force, without being limited thereto.

In some alternative embodiments of the present invention, one end of the reset element 22 is connected to the plunger 212, and the other end of the reset element 22 is connected to the housing 1, so that the reset element 22 can directly apply an elastic force to the plunger 212 in a direction opposite to the movement direction of the plunger 212 during the movement of the plunger 212 and the striker 213.

It can be understood that the connection manner between the reset element 22 and the iron core 212 and between the reset element 22 and the housing 1 may be specifically set according to actual requirements; for example, the reset member 22 may be sleeved on the iron core 212, and the one end of the reset member 22 may be directly clamped on the iron core 212, so that the one end of the reset member 22 moves synchronously with the iron core 212, and meanwhile, the installation and the limitation of the reset member 22 are facilitated, and the operation stability of the reset member 22 is ensured.

In other alternative embodiments of the present invention, one end of the reset element 22 is connected to the striker 213, such that the one end of the reset element 22 can move along with the striker 213, and the other end of the reset element 22 is connected to the housing 1, such that the other end of the reset element 22 can be kept stationary relative to the housing 1, thereby ensuring that the reset element 22 can directly apply an elastic force to the striker 213 opposite to the movement direction of the striker 213 during the movement of the core 212 and the striker 213.

Also, the connection mode between the reset piece 22 and the striker 213, and between the reset piece 22 and the housing 1 may be specifically set according to actual requirements; for example, the resetting member 22 may be sleeved on the striker 213, and the one end of the resetting member 22 may be directly clamped on the striker 213, so that the one end of the resetting member 22 moves synchronously with the striker 213, and meanwhile, the installation and the limitation of the resetting member 22 are facilitated, and the operation stability of the resetting member 22 is ensured.

In a further embodiment of the present invention, as shown in fig. 1 and 2, a cartridge clip 6 for holding the fastening pin 101 is disposed in the housing 1, so as to facilitate the position limitation of the fastening pin 101 and the storage of the fastening pin 101.

Specifically, as shown in fig. 1 and 2, a pusher 61 is provided in the magazine 6 to sequentially push the plurality of fastening pins 101 toward the pin ejection port 120.

Wherein the pusher 61 may be selected as a spring.

For example, in the example of fig. 1 and 2, the trigger switch 110 is movably disposed on the handle portion 11, and a user can press the trigger switch 110 to switch the trigger switch 110 from the normal state to the trigger state, at which time, the trigger switch 110 can trigger the circuit board 5 to make the corresponding capacitor 3 supply power to the electromagnet 21; an elastic member may be disposed in the trigger switch 110, so that when the user does not press the trigger switch 110, the trigger switch 110 may be switched from a trigger state to a normal state under the action of the elastic member.

Alternatively, as shown in fig. 1 and 2, the handle portion 11 may be formed substantially in a cylindrical structure, and the handle portion 11 may be disposed vertically or obliquely (i.e., disposed obliquely with respect to the vertical direction); the handle portion 11 has a first surface and a second surface, which may be sequentially disposed along an axial direction of the handle portion 11, and the trigger switch 110 may be disposed corresponding to the first surface; an edge line of the projection of the first surface corresponding to the annular structure of the housing 1 on the longitudinal center plane of the housing 1 may be formed as a first line segment, an edge line of the projection of the second surface corresponding to the annular structure of the housing 1 may be formed as a second line segment, the second line segment may be formed as a straight line segment and the second line segment may be parallel to the axial direction of the handle portion 11, the first line segment may extend obliquely toward the support portion 14 with respect to the axial direction of the handle portion 11, which facilitates the user to hold the handle portion 11, improves the user's feeling of holding at the same time, and facilitates the user to hold and operate the nail gun 100.

Furthermore, the included angle α between the first line segment and the vertical direction may be 17 °, 20 °, 24 °, or 30 °, which further ensures the holding feeling of the user.

It can be understood that when the second line segment is formed into a straight line segment, the included angle alpha between the extending direction of the second line segment and the vertical direction is more than or equal to 5 degrees and less than or equal to 45 degrees; when the second line segment is formed into a curve segment, the included angle alpha between the tangential direction at any point on the second line segment and the vertical direction meets the condition that alpha is more than or equal to 5 degrees and less than or equal to 45 degrees.

Optionally, at least one of the plurality of capacitors 3 is a super capacitor, and the number of the super capacitors in the plurality of capacitors 3 may be one or multiple, and is less than or equal to the number of the capacitors 3. The super capacitor is a novel energy storage device between a traditional capacitor and a rechargeable battery, and stores energy through an interface double layer formed between an electrode and an electrolyte, so that the super capacitor can be charged and discharged quickly and can also store energy. When the electrode is contacted with the electrolyte, the solid-liquid interface generates stable double-layer charges with opposite signs under the action of coulomb force, intermolecular force and interatomic force, the double-layer charges are called interface double layers, the double-layer super capacitor is regarded as 2 inactive porous plates suspended in the electrolyte, and voltage is loaded on the 2 plates; the potential applied to the positive plate attracts negative ions in the electrolyte and the negative plate attracts positive ions, thereby forming an Electric Double Layer Capacitor (EDLC) on the surfaces of the electrodes.

From this, ultracapacitor system has higher power density, long cycle life, work temperature limit is wide, and bearing capacity is good, need not to maintain, realizes green's effect, under the same electric energy user demand, the required space of arranging of ultracapacitor system is less for ultracapacitor system's position setting has good design flexibility, has made things convenient for nail gun 100's overall arrangement, is convenient for save nail gun 100's occupation space, thereby has further made things convenient for the handheld operation of user.

For example, the power density of the super capacitor can reach up to 102W/kg-104W/kg, the super capacitor can be charged and discharged for 50 ten thousand to 100 ten thousand cycles within a few seconds, the characteristic change is small, and the working temperature range can reach-40 ℃ to 80 ℃.

Optionally, the power source 4 is a charging power source, so that the nail gun 100 can be connected with an external power source through a wire at any time during the use process, the limitation of the distance on the use of the nail gun 100 is avoided, and the use flexibility and convenience of the nail gun 100 are improved.

Here, it should be noted that "charging power source" may refer to the rechargeable power source 4, that is, the charging power source may be connected to an external power source for charging, and the charging power source may supply power to the capacitor 3 after completing charging. For example, the charging power source may be a rechargeable battery.

According to the control method of the nail gun 100 according to the second aspect embodiment of the invention, the nail gun 100 is the nail gun 100 according to the above-described first aspect embodiment of the invention.

As shown in fig. 3 to 6, a plurality of fastening nails 101 are adapted to be previously installed in the nail gun 100, and a control method of the nail gun 100 includes: s1: the trigger power supply 4 charges at least one of the plurality of capacitors 3; s2: triggering one of the charged capacitors 3 to supply power to the electromagnet 21; s3: when one of the capacitors 3 finishes discharging, triggering one of the other capacitors 3 which finishes charging to supply power to the electromagnet 21; s4: the power supply 4 is turned off.

Specifically, prior to use of the nail gun 100, a plurality of fastening nails 101 may be installed in the nail gun 100; then, the nail gun 100 is started to be used, the power supply 4 is triggered to charge at least one of the plurality of capacitors 3, for example, the power supply 4 may be triggered to charge one of the plurality of capacitors 3, or the power supply 4 may be triggered to charge at least two of the plurality of capacitors 3; then, triggering one of the charged capacitors 3 to supply power to the electromagnet 21 through the circuit board 5, so that the corresponding fastening nail 101 (for example, the uppermost one of the fastening nails 101 in fig. 2) is ejected from the nail ejection opening 120, and one capacitor 3 supplies power to the electromagnet 21 to complete nail ejection once; when one of the capacitors 3 is discharged, the charged capacitor 3 can be triggered to supply power to the electromagnet 21 through the circuit board 5 to complete nail shooting, so that the working efficiency of the nail gun 100 is effectively improved, and the nail gun 100 is favorable for realizing rapid and continuous nail shooting. Finally, when the nailer 100 is finished, the power source 4 can be turned off, saving power.

For example, in the example of fig. 1-6, there are two capacitors 3, the two capacitors 3 being a first capacitor 31 and a second capacitor 32, respectively; before using the nail gun 100, a plurality of fastening nails 101 are installed in the nail gun 100; then, the nail gun 100 is started to be used, and the process proceeds to step S1: the trigger power source 4 charges the first capacitor 31 and the second capacitor 32, so that the first capacitor 31 and the second capacitor 32 are charged; then, the process proceeds to step S2: triggering the first capacitor 31 to supply power to the electromagnet 21 through the circuit board 5, so that the electromagnet 21 is switched from the first state to the second state to eject the fastening nail 101, thereby completing the first nail ejection of the nail gun 100, and proceeds to step S3: when the first capacitor 31 finishes discharging, the second capacitor 32 is triggered to supply power to the electromagnet 21, so that the electromagnet 21 is switched from the first state to the second state to eject the fastening nail 101, and the second nail ejection of the nail gun 100 is finished. Finally, the power supply 4 is turned off.

According to the control method of the nail gun 100 provided by the embodiment of the invention, the working efficiency of the nail gun 100 is effectively improved, and the nail gun 100 can conveniently realize quick and continuous nail shooting.

Further, as shown in fig. 4 and 6, the control method further includes step S5: it is determined whether or not it is necessary to continue to eject the fastener 101, and if so, the flow proceeds to step S3, and if not, the trigger is stopped. Step S5 is set between step S2 and step S3, that is, after one of the capacitors 3 that has completed charging is triggered to supply power to the electromagnet 21 in step S2, it is necessary to determine whether to continue to eject the fastening pin 101, and if necessary, step S3 is performed to trigger one of the other capacitors 3 that has completed charging to supply power to the electromagnet 21 after one of the capacitors 3 completes discharging, and if not, the triggering is stopped. This improves the degree of intelligence of the nail gun 100.

For example, in the examples of fig. 1, 4 and 6, there are two capacitors 3, the two capacitors 3 being a first capacitor 31 and a second capacitor 32, respectively; after the first capacitor 31 is triggered to supply power to the electromagnet 21 through the circuit board 5 in step S2, it is necessary to determine whether to continue to eject the fastening nail 101, if necessary, step S2 is performed to trigger the second capacitor 32 to supply power to the electromagnet 21, and if not, the triggering is stopped; finally, the power supply 4 is turned off.

It is to be understood that the determination of whether or not the fastener 101 needs to be ejected continuously in step S5 may be performed by the user or by the nail gun 100 itself, but is not limited thereto.

Further, as shown in fig. 5 and 6, the control method further includes step S6: when the capacitor 3 starts to be discharged, it is determined whether or not there is a case where charging is not performed in the remaining capacitors 3, and if so, the power source 4 charges the capacitor 3 that is not charged, and if not, the process proceeds to step S3. That is, when one of the capacitors 3 whose charging is completed is triggered to supply power to the electromagnet 21 in step S2, it is determined whether any capacitor 3 among the remaining capacitors 3 is uncharged (or it is determined whether any capacitor 3 among the remaining capacitors 3 is in the non-charged state), and if so, any capacitor 3 among the remaining capacitors 3 is uncharged, and the power supply 4 charges the capacitor 3 which is not charged, so that the power supply 4 can charge the capacitor 3 which is in the non-charged state in preparation for the next discharge of the capacitor 3 in the process of triggering one of the capacitors 3 whose charging is completed in step S2, and if not, no capacitor 3 among the remaining capacitors 3 is uncharged, and the triggering is stopped. Therefore, the capacitor 3 which is not charged in the rest capacitors 3 among the plurality of capacitors 3 can be charged in the discharging process of one capacitor 3 in the step S2 during the nail-shooting process of the nail-shooting gun 100, so as to further shorten the time interval between two adjacent nail-shooting processes, realize the cyclic operation of charging and discharging the plurality of capacitors 3 for a plurality of times, and further facilitate the long-term rapid continuous nail-shooting of the nail-shooting gun 100.

For example, in the examples of fig. 1, 5 and 6, there are two capacitors 3, the two capacitors 3 being a first capacitor 31 and a second capacitor 32, respectively; when the first capacitor 31 is triggered to supply power to the electromagnet 21 through the circuit board 5 in step S2, it is necessary to determine whether or not there is a non-charging condition in the second capacitor 32, if so, the power source 4 charges the non-charging capacitor 3, and if not, the triggering is stopped; finally, the power supply 4 is turned off.

It is to be understood that if the power source 4 charges the capacitor 3 that is not being charged in step S6, the charging process may be completed simultaneously with or not simultaneously with the discharging process of the capacitor 3 in step S2; for example, when the charging process of the capacitor 3 in step S6 and the discharging process of the capacitor 3 in step S2 are not simultaneously completed, the charging process of the capacitor 3 in step S6 may be completed before the discharging process of the capacitor 3 in step S2, that is, the charging process of the capacitor 3 in step S6 is completed first and the discharging process of the capacitor 3 in step S2 is completed later, or the charging process of the capacitor 3 in step S6 may be completed later than the discharging process of the capacitor 3 in step S2, that is, the discharging process of the capacitor 3 in step S2 is completed first and the charging process of the capacitor 3 in step S6 is completed later.

For example, in the example of fig. 1-6, the discharge time of the first capacitor 31 in step S2 may be equal to the charge time of the second capacitor 32 in step S6, may be greater than the charge time of the second capacitor 32 in step S6, or less than the charge time of the second capacitor 32 in step S6.

In step S1, step S2, step S3, step S4, step S5, and step S6, the sequence numbers of the steps do not represent the execution order of the steps.

Specifically, as shown in fig. 1 and fig. 2, a control chip 51 and a plurality of charge-discharge modules 52 are disposed on the circuit board 5, the control chip 51 is in communication connection with each charge-discharge module 52, and the plurality of charge-discharge modules 52 are connected to the plurality of capacitors 3 in a one-to-one correspondence manner to control the charge-discharge state of the corresponding capacitor 3, that is, each charge-discharge module 52 controls the charge or discharge of the corresponding capacitor 3. It is understood that each charge and discharge module 52 may have a first state and a second state, respectively, and each charge and discharge module 52 may be switched between the first state and the second state such that the corresponding capacitor 3 may be charged after being discharged or discharged after being charged.

For example, in the example of fig. 1 and 6, the two capacitors 3 are the first capacitor 31 and the second capacitor 32, the two charge-discharge modules 52 are the first charge-discharge module and the second charge-discharge module, respectively, the first charge-discharge module is connected to the first capacitor 31, and the second charge-discharge module is connected to the second capacitor 32; starting to use the nail gun 100, the first capacitor 31 and the second capacitor 32 sequentially supply power to the electromagnet 21 by turns through the circuit board 5, so that the fastening nails 101 are sequentially ejected from the nail ejection port 120; firstly, the first charge-discharge module controls the first capacitor 31 to discharge so as to supply power to the electromagnet 21 through the circuit board 5, thereby completing the first nail shooting of the nail gun 100, when the nail gun 100 needs to shoot nails again, the second charge-discharge module controls the second capacitor 32 to discharge so as to supply power to the electromagnet 21 through the circuit board 5, thereby completing the second nail shooting of the nail gun 100, in the second nail shooting process, the first charge-discharge module can enable the power source 4 to charge the first capacitor 31, when the nail gun 100 needs to shoot nails for the third time, the first capacitor 31 which completes the charging supplies power to the electromagnet 21 through the circuit board 5 again, thereby realizing the nail shooting, and the cycle is repeated. Here, the discharge time of the first capacitor 31 in the step S2 may be equal to the charge time of the second capacitor 32 in the step S6.
