[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings, in which the same reference numerals denote the same or similar configurations.

[0009] Please refer to Figures 1 to 12. As shown in Figures 1 to 12, an electric nail driver 1 according to one embodiment of the present invention includes a main body 100, a limiting mechanism, a passive mechanism, a magnetic attraction mechanism, an active mechanism, a nail driving mechanism, a safety mechanism, and a lithium battery case 104.

[0010] The main body 100 has a housing section 110, a handle section 120, a stock section 130, and a nail magazine section 140. The handle section 120 is connected to the housing section 110 and the stock section. The handle section 120 includes a hand-held area 121 and a trigger area 122 that are adjacent to each other in a staggered manner. The hand-held area 121 has a motor switch 101. The trigger area 122 has a trigger switch 102. Frame plates 111 are provided in the housing section 110 and are spaced apart from each other. A head assembly 150 is attached to one end of the housing section 110. The nail magazine section 140 is connected to the head assembly 150 and the stock section 130. The stock section 130 has a power switch 103. The main body 100 described above is made up of two housings that are combined with each other in both directions, but does not include the nail magazine section 140.

[0011] The limiting mechanism includes an initial rod 210 and a terminal rod 220 that are installed at a distance from each other between the frame plates 111. The terminal rod 220 is closer to the head assembly 150 than the initial rod 210. The outer periphery of the initial rod 210 and the terminal rod 220 is covered with an elastic body (e.g., rubber or foam), and when the needle driving mechanism is displaced and collides, the elastic body deforms to absorb the collision force, preventing direct damage to the structure.

[0012] The passive mechanism is located between the frame plates 111 and includes a pulley 310, a diverting wheel 320, and a belt 330. The belt 330 is wound around the diverting wheel 320 and the pulley 310. The belt 330 is in meshing contact with the pulley 310. The belt 330 is a timing belt, for example, and meshes with the outer periphery of the pulley 310. The number of diverting wheels 320 is two, for example.

[0013] The magnetic attraction mechanism includes an electromagnet 410 and a cam 420. The electromagnet 410 is attached to the outside of the frame plate 111 and is located in the plate hole 112 of the frame plate 111. The cam 420 is arranged to be swingable in the tank portion 311 of the pulley 310. A wheel hole 312 corresponding to the plate hole 112 of the frame plate 111 and the magnetic attraction end 421 of the cam 420 is formed in the tank bottom of the tank portion 311. The cam 420 is made of a high magnetic permeability material. The cam 420 is installed by inserting an axis member into the tank portion 311. The cam 420 is swingable relative to the axis member.

[0014] The active mechanism is located in the housing portion 110 of the main body 100. The active mechanism includes a motor 510 and a wheel 520 that is rotated by the motor 510. The wheel 520 has a drive block 530 facing the pulley 310. Take the above-mentioned motor 510 as an example, which can reach 8000 rpm or more.

[0015] The nail driving mechanism includes a fixed seat 610 and a striker 620. The fixed seat 610 is fixed on the belt 330 and is located between the initial rod 210 and the terminal rod 220. The striker 620 has one end fixed to the fixed seat 610 and the other end facing the head assembly 150.

[0016] The safety mechanism is disposed in the head assembly 150. The safety mechanism includes a safety switch 710 and a safety slider 720.

[0017] The lithium battery case 104 is detachably connected to the stock 130. The lithium battery case 104 is electrically connected to the motor 510, the electromagnet 410, the power switch 103, the motor switch 101, the safety switch 710, and the trigger switch 102. See Fig. 13. The power switch 103, the motor switch 101, the safety switch 710, and the trigger switch 102 are connected to the negative terminal of the lithium battery case 104.

[0018] In actual use, when the power switch 103 and the motor switch 101 are turned on in sequence, the motor 510 starts to rotate the wheel 520. Since the motor switch 101 is provided in the hand-held area 121, when a user picks up the electric nail gun 1, the user habitually grips the hand-held area 121, and this action presses the motor switch 101, so that with the power switch 103 turned on, the motor 510 can be quickly started to operate the wheel 520. When the electric nail gun 1 is moved and the safety slider 720 is pressed against a target to slide with the head assembly 150, the safety switch 710 is triggered. When the trigger switch 102 is pressed, a magnetic force is generated in the electromagnet 410, which attracts the magnetically attracted end 421 of the cam 420 and swings it toward the plate hole 112, causing a part of the protruding end 422 of the cam 420 to protrude outside the tank portion 311 until it reaches the rotating wheel 520, and the driving surface 531 of the driving block 530 comes into contact with and pushes it, causing the wheel 520 to drive the pulley 310, which begins to rotate from the initial state, the pulley 310 synchronously meshes with the belt 330, and the fixed seat 610 of the nail driving mechanism moves from the initial position of the initial rod 210 to the nail driving position of the terminal rod 220.

[0019] The following describes the detailed features of the electric nail driver 1 according to the present invention and the effects achieved by combining the operations. The frame plate 111 has a slide rail 113 formed penetrating from the inner surface to the outer surface. The extension direction of both ends of the slide rail 113 faces the directions of the initial rod 210 and the terminal rod 220. The fixed seat 610 has a slide rod 611 attached thereto and slides on the slide rail 113. The fixed seat 610 forms a displacement trajectory along the slide rail 113 via the slide rod 611.

[0020] In this embodiment, a pressure plate 114 is disposed in the housing part 110. One end of the pressure plate 114 extends between the frame plates 111. The wheel 520 contacts the protruding end 422 extending outside the tank part 311 via the driving surface 531, and when the wheel 520 indirectly drives the pulley 310 to reach the position of the pressure plate 114, the protruding end 422 of the cam 420 is restricted by the pressure plate 114, the protruding end 422 retracts, and is displaced into the tank part 311 and not exposed, so that the wheel 520 is in a disengaged state where it does not drive the pulley 310, and the pulley 310 does not rotate more than once during the process of the pulley 310 moving from the initial state to the disengaged state.

[0021] In this embodiment, one end of a spring 105 is attached to the outer surface of the frame plate 111. The other end of the spring 105 is attached to a slide rod 611. When driving a nail, the spring 105 is pulled to generate a biasing force, and after the nail is driven, the restoring force of the spring 105 resets the nail driving mechanism, and simultaneously, the pulley 310 is reset by the belt 330.

[0022] The frame plate 111 of this embodiment has a tension track 115 formed through it from the inner surface to the outer surface. Some of the direction-changing wheels 320 are displaceably disposed on the tension track 115. The extension directions of both ends of the tension track 115 are toward the head assembly 150 and away from the head assembly 150. The above-mentioned arrangement allows the tension of the belt 330 to be adjusted, the pulley 310 to be accurately positioned at the initial state position, the cam 420 to be installed at an appropriate position, and the accurate swing position to be obtained in advance by the magnetic attraction of the electromagnet 410.

[0023] In this embodiment, the fixing seat 610 and the fixing piece 630 are fixed in a state where both ends of the belt 330 do not overlap. The fixing seat 610 and the fixing piece 630 are respectively located on the upper surface and the lower surface of the belt 330, and are screwed in place with bolts. In the above-mentioned arrangement, in addition to connecting and fixing the nail driving mechanism and the belt 330, the connection at both ends of the belt 330 is formed into a ring shape and smoothly wound around the direction-changing wheel 320 and the pulley 310.

[0024] In this embodiment, the pulley 310 is provided with a shielding plate 340 on one side facing the electromagnet 410. The shielding plate 340 has a shielding hole 341 corresponding to the wheel hole 312. The shielding plate 340 is made of a low magnetic permeability material (e.g., an aluminum material). With the above-mentioned arrangement, when the electromagnet 410 is activated, the shielding plate 340 limits or blocks the magnetic force direction, reducing the direct effect on the pulley 310 when the electromagnet 410 is activated. At the same time, the cam 420 that passes through the position of the shielding hole 341 and is attracted oscillates in the tank portion 311, and a part of the protruding end 422 moves smoothly at the outer position of the tank portion 311.

[0025] In this embodiment, the driving surface 531 widens from the direction of the wheel 520 (defined as the inward end) to the direction away from the wheel 520 (defined as the outward end). The angle between the inward end and the outward end is 7 degrees. With the above-mentioned arrangement, when the driving block 530 comes into contact with the cam 420 and rotates with it, the driving block 530 instantaneously comes into contact with the surface of the protruding end 422 located on the outside of the tank part 311 through the inclined driving surface 531, and the two are in a planar contact type rather than a direct contact type, and the driving block 530 instantaneously comes into contact with the cam 420, and the driving block 530 has a large resistance to the reaction force generated by the contact. Therefore, the arrangement adopted in the above-mentioned technology can increase the durability of the product of the driving block 530 of the wheel 520.

[0026] In this embodiment, the cam 420 has a receding surface 423 and a rising surface 424, and is generally oriented toward the bottom surface of the tank part 311. The receding surface 423 and the rising surface 424 are not formed on the same surface. When the cam 420, the magnetically attracted end 421, and the protruding end 422 are positioned within the tank part 311, the cam 420 contacts the bottom surface of the tank part 311 via the receding surface 423. When a part of the protruding end 422 of the cam 420 protrudes outside the tank part 311, the cam 420 contacts the bottom surface of the tank part 311 via the rising surface 424. Due to the above-mentioned arrangement, particularly when the rising surface 424 contacts the bottom surface of the tank part 311, a part of the action force of the drive block 530 received by the cam 420 is transmitted to the bottom surface of the tank part 311, preventing the concentration of the force received by the cam 420 and the shaft member, and obtaining a high durability of the product.

[0027] In the electric nail driver 1 according to the present invention, the method of transmitting power by meshing the belt 330 and pulley 310 as in the above-mentioned embodiment may be substituted by a chain 350 and a gear 360. FIGS. 14 and 15 show a state in which the method of transmitting power by meshing the gear 360 and the chain 350 replaces the original method of driving the belt 330 by the pulley 310.

[0028] Please refer to Fig. 16. As shown in Fig. 16, the method for operating the electric nail driver according to the present invention includes the following steps (S10) to (S40).

[0029] Step of turning on the power switch (S10): First, the power switch 103 located on the stock portion 130 of the main body 100 is turned on.

[0030] Step of turning on motor switch (S20): When the hand-held area 121 of the main body 100 is gripped and the motor switch 101 located in the hand-held area 121 is turned on, the motor 510 continues to rotate the wheel 520.

[0031] Step of turning on the safety switch (S30): After the electric nail gun 1 is moved to the target, when the safety slider 720 is brought into contact with the target, the head assembly 150 slides to trigger the safety switch 710.

[0032] Step of turning on trigger switch (S40): When trigger switch 102 in trigger area 122 of handle portion 120 is turned on, magnetic force is generated in the electromagnet, attracting and swinging cam 420, causing a part of protruding end 422 of cam 420 to protrude outside trough portion 311 of pulley 310. When protruding end 422 is pushed by drive block 530 of wheel 520, wheel 520 starts rotating pulley 310 from its initial position, pulley 310 meshes with belt 330 in synchronism, and the nail driving mechanism can be moved from the initial position to the nail driving position.
