DETAILED DESCRIPTION

[0026] like Figures 1 to 7 As shown, the sliding guide structure of the lithium-electric nail gun includes a housing 1, an energy storage component 2, a guide component 3, a power component 4 and a gun needle 5.

[0027] Further, such as Figure 4 As shown, the guide assembly 3 is installed in the housing 1, including a front cover 301, a rear cover 302 and a guide rod 303, wherein guide plates 304 are provided at both ends of the guide rod 303, one end of the guide plate 304 is connected to the front cover 301, and the other end is connected to the rear cover 302, and a groove is provided on the guide plate 304.

[0028] The arrangement of the guide rod 303 and the guide plate 304 provides linear guidance for the movement of the push plate 201, thereby ensuring high precision of the shooting trajectory.

[0029] Further, such as Figure 5 to Figure 6 As shown, the energy storage assembly 2 includes a push plate 201, a first spring 202 and a second spring 203, wherein a baffle 204 is fixedly provided at the bottom of the push plate 201, a positioning rod 205 is fixedly provided at the top of the push plate 201, protrusions 206 are fixedly provided at both ends of the push plate 201, a positioning ring 207 is fixedly provided on the push plate 201, and a connecting hole is also opened on the push plate 201, which is connected to the inside of the positioning ring 207, and the connecting hole and the positioning ring 207 are both slidably arranged On the guide rod 303, one end of the first spring 202 is installed on the push plate 201, and the other end is installed on the rear end cover 302; one end of the second spring 203 is installed on the positioning ring 207, and the other end is installed on the rear end cover 302. One end of the baffle 204 is a protrusion, which is connected to the driving rod 404. The baffle 204 extends to one end along the center line position of the push plate 201. The shape of the protrusion 206 is adapted to the collision of the groove, and is slidably set in the groove.

[0030] The first spring 202 and the second spring 203 are installed, and the double spring setting forms a double energy storage mechanism, which ensures uniform and strong thrust and optimizes nail shooting efficiency.

[0031] Since the baffle 204 only occupies half of the push plate 201 , the driving rod 404 drives the baffle 204 to move a certain distance and then moves to the other side of the push plate 201 to separate from the baffle 204 .

[0032] Further, such as Figure 7 As shown, the power assembly 4 is installed inside the housing 1, including a motor 401, a reduction gearbox 402 and a connecting disk 403, wherein a driving rod 404 is installed on the connecting disk 403 to cooperate with the baffle 204 to drive the push plate 201 to move, and the reduction gearbox 402 is a planetary gear reduction gearbox, one end of which is installed on the output end of the motor 401, and the other end is installed on the connecting disk 403.

[0033] The push plate 201 can be moved smoothly and efficiently by the drive of the motor 401 and the fine regulation of the reduction box 402 .

[0034] Furthermore, a gun nozzle 6 is installed on the front end cover 301 , and a magazine 7 is installed on the gun nozzle 6 .

[0035] The clip 7 is used to assemble rows of nails.

[0036] Furthermore, one end of the gun needle 5 is mounted on the positioning rod 205 , and the other end is slidably disposed in the gun nozzle 6 .

[0037] The push plate 201 drives the gun needle 5 to reciprocate in the gun nozzle 6 to eject the nail.

[0038] The sliding guide structure of the lithium battery nail gun works as follows:

[0039] The motor 401 drives the reduction box 402, which in turn drives the reduction box 402, and reduces speed through the planetary gear set inside the reduction box 402, driving the connecting plate 403 to rotate, and the connecting plate 403 drives the driving rod 404 thereon to move, and then drives the baffle plate 204, so that the push plate 201 moves, and the push plate 201 moves linearly under the dual limit of the guide rod 303 and the guide plate 304, and drives the gun needle 5 to move, and compresses the first spring 202 and the second spring 203 synchronously. When the driving rod 404 moves to the other end position under the push plate 201, it no longer contacts the baffle plate 204, so that the baffle plate 204 is no longer under force, and the push plate 201 is driven to reset under the action of the first spring 202 and the second spring 203, thereby driving the gun needle 5 to move.
