[0060] The impact column 321 is arranged through the center of the conductive plate 500 so that the conductive plate 500 is sleeved on the outer circumference of the impact column 321. By setting the impact column 321 to be arranged through the center of the conductive plate 500 so that the conductive plate 500 is sleeved on the outer circumference of the impact column 321, the conductive plate 500 has a good conductive effect, and the impact column 321 is prevented from affecting the construction of the conductive circuit.

[0061] In some embodiments, the pen housing 100 is provided with a positioning groove 140, and the control component 300 includes a sliding member 311 and a lever 312, the sliding member 311 is provided inside the pen housing 100, and the lever 312 is passed through the sliding member 311 and the positioning groove 140, and the lever 312 is used to drive the sliding member 311 to move in the pen housing 100 to trigger the lighting switch 210 in the power supply component 200, wherein the lever 312 and the sliding member 311 are telescopically connected and the telescopic direction is perpendicular to the direction of the axis of the pen housing 100, so that the lever 312 is retracted relative to the sliding member 311 when it is clamped in the positioning groove 140, and is extended relative to the sliding member 311 when the lever 312 is separated from the positioning groove 140.

[0062] A refill 120 is disposed in the pen housing 100 , and a first elastic member 130 is disposed at the end of the refill 120 away from the power supply assembly 200 . The sliding switch 310 moves in a direction away from the power supply assembly 200 and pushes the refill 120 to squeeze the first elastic member 130 , so that the refill 120 extends out of the pen housing 100 .

[0063] The sliding member 311 slides toward the lighting switch 210, and can push the impact plate 320 to control the opening and closing of the lighting device 230; when the sliding member 311 slides toward the pen tip, it pushes the pen core 120 to squeeze the first elastic member 130. It can be understood that the first elastic member 130 is a spring, one end of which is against the tip of the pen, and the other end is against the end of the pen core 120. The pen core 120 is pushed and squeezed by the sliding member 311 until it extends out of the pen tip. At this time, the end of the limiting groove 110 is provided with a bending section 111, so that the lever 312 can be drawn into the bending section 111, so as to realize the positioning of the sliding member 311 and keep the pen core 120 in the extended posture. The extension direction of the bending section 111 is perpendicular to the axis of the pen housing 100. When writing is finished, the lever 312 is slid out of the bent section 111 and slides toward the tail along the straight section direction of the limiting groove 110. At this time, the lever 312 drives the sliding member 311 to leave the position of the tail of the pen core 120, and the spring rebounds the pen core 120 to retract into the pen case 100. The pen core 120 is arranged in the pen case 100, and the end of the pen core 120 away from the power supply component 200 is provided with a first elastic member 130. The sliding switch 310 moves in a direction away from the power supply component 200 and pushes the pen core 120 to squeeze the first elastic member 130, so that the pen core 120 extends out of the pen case 100. When the sliding switch 310 moves in the opposite direction, the switch of the lighting device 230 and the ejection of the pen core 120 can be controlled respectively, and the operation is convenient. At the same time, the positioning groove 140 can prevent the pen core 120 from rushing out of the pen case 100 when the pen light falls, causing damage to the pen tip.

[0064] The pen housing 100 is provided with a limiting groove 110 , and the end of the lever 312 is arranged to pass through the limiting groove 110 , so that when the lever 312 moves along the limiting groove 110 , the sliding member 311 is driven to move.

[0065] It can be understood that the length direction of the limiting groove 110 is arranged along the axis direction of the pen housing 100 to form a long strip of limiting groove 110 on the surface of the pen housing 100, and the movement direction of the lever 312 is also along the axis direction of the pen housing 100. After the lever 312 passes through the limiting groove 110, it is inserted into the limiting hole 313 of the sliding member 311. The user moves the lever 312 along the limiting groove 110, so that the lever 312 drives the sliding member 311 to move in the pen housing 100, and controls the lighting, which is convenient and quick to use. By providing the limiting groove 110 in the pen housing 100, the end of the lever 312 passes through the limiting groove 110, so that when the lever 312 moves along the limiting groove 110, the sliding member 311 is driven to move, so that the lever 312 slides in the limiting groove 110, and the lever 312 is prevented from exceeding the preset stroke when sliding. As a result, the lighting switch 210 is damaged.

[0066] The limiting hole 313 is provided with a second elastic member 150, which is used to pop the lever 312 out of the sliding member 311 when the lever 312 is separated from the positioning slot 140. In this way, by providing the second elastic member 150 in the limiting hole 313, which is used to pop the lever 312 out of the sliding member 311 when the lever 312 is separated from the positioning slot 140, the lever 312 can rise quickly when the lever 312 is separated from the positioning slot 140, so as to provide the user with control, thereby improving the user experience.

[0067] When using the penlight, the user needs to press the lever 312, and the lever 312 squeezes the second elastic member 150, so that the lever 312 is separated from the positioning groove 140, and the lever 312 can move up and down along the axis of the pen housing 100 in the limiting groove 110, thereby driving the sliding member 311 to move up and down. When the sliding member 311 moves upward, the lighting switch 210 can be pressed; when the sliding member 311 moves downward, the pen core 120 can be pushed to squeeze the first elastic member 130, so that the pen core 120 extends out of the pen housing 100. By arranging the lever 312 and the sliding member 311 to be telescopically connected and the telescopic direction is perpendicular to the direction of the axis of the pen housing 100, the lever 312 can be retracted relative to the sliding member 311 when it is clamped in the positioning groove 140, and can be extended relative to the sliding member 311 when the lever 312 is separated from the positioning groove 140. Only when the lever 312 is separated from the positioning groove 140 can the lighting device 230 be slidably controlled to be turned on or off along the axis of the pen housing 100, thereby preventing the lever 312 from being displaced when the pen light falls, causing damage to the internal components.

[0068] The sliding member 311 is provided with a limiting hole 313, the axis of which is perpendicular to the axis of the sliding member 311, and the lever 312 is inserted into the limiting hole 313. A limiting portion 314 is provided at the end of the lever 312, and the limiting portion 314 is used to limit the lever 312 in the limiting groove 110 along a direction perpendicular to the axis of the pen housing 100. A limiting rib 330 is provided in the limiting hole 313, and an abutting member 340 is provided at the bottom of the lever 312. When the lever 312 is separated from the positioning groove 140, the abutting member 340 abuts against the limiting rib 330 to prevent the lever 312 from being separated from the sliding member 311. A limiting sleeve 350 is provided at a position of the lever 312 near the positioning groove 140, and the limiting sleeve 350 is used to be engaged with or separated from the positioning groove 140, and the second elastic member 150 is provided between the limiting sleeve 350 and the limiting rib 330. By providing a limiting rib 330 in the limiting hole 313 and providing an abutment member 340 at the bottom of the lever 312, the abutment member 340 abuts against the limiting rib 330 when the lever 312 is separated from the positioning groove 140, so as to prevent the lever 312 from being separated from the sliding member 311, so that when the lever 312 is separated from the positioning groove 140, the lever 312 will not be completely separated from the sliding member 311, resulting in the loss and damage of parts. By providing a limiting sleeve 350 at a position close to the positioning groove 140 of the lever 312, the limiting sleeve 350 is used to be engaged with or separated from the positioning groove 140, and the second elastic member 150 is provided between the limiting sleeve 350 and the limiting rib 330, so that the limiting sleeve 350 limits the lever 312 below the positioning groove 140, further preventing the lever 312 from being separated from the positioning groove 140 when the penlight falls.

[0069] It can be understood that the lever 312 is a cylindrical lever and is inserted into the sliding member 311. The axis of the lever 312 is arranged perpendicular to the axis of the sliding member 311. A pair of clamps perpendicular to the axis of the sliding member 311 are arranged in the sliding member 311, and a limiting hole 313 is formed between the two clamps. The clamps can provide support for the lever 312 to prevent the lever 312 from breaking due to excessive stress between the lever 312 and the sliding member 311 when the lever 312 drives the sliding member 311 to move. The limiting portion 314 is arranged at the end of the lever 312, and the projection width of the limiting portion 314 on the limiting groove 110 is greater than the width of the limiting groove 110, so that the lever 312 will not fall from the limiting groove 110, thereby causing the user to be unable to operate the lever 312. The limiting portion 314 can be spherical, cylindrical, or sheet-like or plate-like. This embodiment does not specifically limit the structure of the limiting portion 314. By providing a limiting hole 313 in the sliding member 311, the axis of the limiting hole 313 is arranged perpendicular to the axis of the sliding member 311, and the lever 312 is inserted into the limiting hole 313, so as to prevent the lever 312 from separating from the sliding member 311 when driving the sliding member 311 to move, so as to make the lever 312 more stable when driving the sliding member 311 to move. By providing a limiting portion 314 at the end of the lever 312, the limiting portion 314 is used to limit the lever 312 in the limiting groove 110 along the direction perpendicular to the axis of the pen housing 100, so as to prevent the lever 312 from falling in the limiting hole 313, so as to prevent the lever 312 from controlling the sliding member 311 to slide, and thus ensure the stability of the lever 312.

[0070] The end of the slider 311 facing the refill 120 forms a limiting cavity 316, and the end of the refill 120 is disposed in the limiting cavity 316. The end of the slider 311 facing the refill 120 forms a limiting cavity 316 adapted to the tail of the refill 120, so that the tail of the refill 120 can be clamped and fixed in the limiting cavity 316, so that the slider 311 and the refill 120 are stably connected. Preferably, a spring piece 317 is provided in the limiting cavity 316, and the spring piece 317 is clamped at the tail of the refill 120, further improving the tightness of the connection between the slider 311 and the refill 120. By forming the limiting cavity 316 at the end of the slider 311 facing the refill 120, the end of the refill 120 is disposed in the limiting cavity 316, so that the connection between the refill 120 and the slider 311 is more stable and reliable, and the slider 311 will not deviate from the refill 120 when pushing the refill 120 to pop out.

[0071] When the user uses the penlight and needs lighting, the user slides the sliding switch 310 along the pen housing 100, so that the sliding switch 310 moves toward the power supply assembly 200 at the rear of the penlight. A push-type lighting switch 210 is provided at the connection between the power supply assembly 200 and the pen housing 100. When the sliding switch 310 touches the lighting switch 210 and is pressed, the lighting switch 210 can control the on and off of the lighting device 230 to complete the lighting. By using the sliding switch 310 to slide along the pen housing 100, the sliding switch 310 slides to touch the lighting switch 210 in the power supply assembly 200 toward the sliding switch 310 to control the on and off of the lighting device 230 in the power supply assembly 200. The operation is simple, and the user can conveniently and quickly switch the lighting device 230, thereby improving the user's use experience.

[0072] The lever 312 extends into the pen housing 100 and is connected to the sliding member 311 , so that the lever 312 can be exposed to the outside of the pen housing 100 , which is convenient for the user to control and drives the sliding member 311 to move inside the pen housing 100 .

[0073] The sliding member 311 is disposed inside the pen housing 100 and connected to the lever 312, so that the lever 312 drives the sliding member 311 to slide inside the pen housing 100, so that the lever 312 controls the sliding member 311 to slide toward the lighting switch 210 to realize the switch of the lighting device 230, which is easy to operate.

[0074] The power supply 220 includes a battery and a charging device, both of which are arranged inside the power supply component 200, and a charging interface electrically connected to the charging device is provided on the outer surface of the power supply component 200. In this way, by setting the power supply 220 to include a battery and a charging device, both of which are arranged inside the power supply component 200, and a charging interface electrically connected to the charging device is provided on the outer surface of the power supply component 200, the lighting device 230 can be powered by the battery and the charging device, thereby extending the lighting time of the lighting device 230.

[0075] The control assembly 300 further includes an impact plate 320 , which is disposed inside the pen housing 100 and between the sliding member 311 and the lighting switch 210 . When the sliding member 311 slides toward the lighting switch 210 , the impact plate 320 is pushed to move toward the lighting switch 210 .

[0076] It can be understood that the impact plate 320 is a circular plate adapted to the inner cavity of the pen housing 100, and is used to press the lighting switch 210. The impact plate 320 is arranged between the sliding member 311 and the lighting switch 210, and can move in the pen housing 100. When the lever 312 drives the sliding member 311 to move toward the lighting switch 210, it abuts against the impact plate 320 and pushes the impact plate 320 to move toward the lighting switch 210. The surface of the impact plate 320 away from the sliding member 311 eventually abuts against the lighting switch 210 and presses the lighting switch 210 to turn on the lighting. When the impact plate 320 is used to press the lighting switch 210, the lighting switch 210 can be conveniently set at any position in the plane, which is convenient for space utilization in the pen housing 100.

[0077] A baffle 315 perpendicular to the axis of the sliding member 311 is provided inside the sliding member 311, and the impact plate 320 is connected to the impact column 321 on the surface facing the sliding member 311. When the sliding member 311 moves toward the lighting switch 210, the baffle 315 abuts against the end of the impact column 321 to push the impact column 321 and the impact plate 320 to move. By providing a baffle 315 perpendicular to the axis of the sliding member 311 inside the sliding member 311, the impact plate 320 is connected to the impact column 321 on the surface of the sliding member 311. When the sliding member 311 moves toward the lighting switch 210, the baffle 315 abuts against the end of the impact column 321 to push the impact column 321 and the impact plate 320 to move. When the lever 312 drives the sliding member 311 to move toward the lighting switch 210, the baffle 315 in the sliding member 311 abuts against the impact column 321 and pushes the impact plate 320 to move toward the lighting switch 210, thereby increasing the contact area between the sliding member 311 and the impact plate 320, and making the movement of the impact plate 320 more stable and reliable. By setting the control component 300 to also include an impact plate 320, the impact plate 320 is arranged inside the pen case 100 and between the sliding member 311 and the lighting switch 210. When the sliding member 311 slides toward the lighting switch 210, it pushes the impact plate 320 to move toward the lighting switch 210, so that the lever 312 drives the sliding member 311 to slide toward the lighting switch 210 in the pen case 100 until the sliding member 311 abuts against the impact plate 320, and then the sliding member 311 pushes the impact plate 320 to touch the lighting switch 210, thereby realizing the switch of the lighting device 230, so that the lighting switch 210 is evenly stressed when it is touched, thereby preventing the lighting switch 210 from being damaged due to uneven stress, and extending the service life of the lighting switch 210.
