[0027] In one embodiment of the present invention, Figure 1-Figure 5 As shown, a retractable and extendable electronic touch pen is provided, including: a main body 1, a storage block 3 is slidably connected inside the main body 1, a pressure-sensitive capacitor 304 is arranged inside the storage block 3, and a pen head 4 is arranged at the bottom of the storage block 3; a telescopic component, the telescopic component is arranged at the bottom of the main body 1, and is used to cooperate with the pen head 4 to extend and retract; a sensor component, the sensor component is arranged at the bottom of the storage block 3, and is used to cooperate with the pen head 4 to improve the pressure detection accuracy; and a placement component, the placement component is arranged at the top of the main body 1, and is used to fix and place the main body 1.

[0028] The telescopic assembly includes: a storage chamber 2 opened at the bottom of the main body 1, a guide rod 201 is provided on the inner wall of the top of the storage chamber 2; a guide groove 301 is opened at the top of the storage block 3, and the guide rod 201 is slidably connected to the guide groove 301; an extrusion block 202 slidably connected to both sides of the main body 1, an extrusion spring 203 is provided between the extrusion block 202 and the guide rod 201, and a push rod 204 is provided on one side of the extrusion block 202, and the end of the push rod 204 is rotatably connected to the storage block 3. When the device is not in use, the extrusion spring 203 will push the extrusion block 202 to move in a direction away from the guide rod 201, and at this time the extrusion block 202 will The push rod 204 is pulled, and the storage block 3 and the pen tip 4 are pulled by the push rod 204, so that the pen tip 4 can be stored in the storage cavity 2, and then the pen tip 4 can be stored in the storage cavity 2 for protection, thereby improving the protection capability of the device. When the user needs to extend the pen tip 4 out of the storage cavity 2 for use, the user can press the two squeezing blocks 202 in a pen-holding posture. At this time, the two squeezing blocks 202 squeeze the squeezing spring 203 and push the push rod 204 to move. The push rod 204 will push the storage block 3 downward and extend the storage block 3 and the pen tip 4 out of the storage cavity 2. At this time, the user can use the pen tip 4 to write on the touch screen.

[0029] Among them, the sensing component includes: a driving groove 302 opened at the bottom of the storage block 3, and the pressure-sensing capacitor 304 is located above the driving groove 302; a driving platform 401 is arranged at the top of the pen head 4, and a plurality of driving rods 402 are arranged on the top of the driving platform 401, and the driving rods 402 are slidably connected with the driving groove 302; a reset spring 305 is arranged between the storage block 3 and the driving platform 401. During use, the writing instruction can be completed by moving the pen head 4 to drive the driving rod 402 and the pressure-sensing capacitor 304 above to contact and squeeze each other, and the push of the reset spring 305 can keep the pen head 4 away from the storage block 3. When the user needs to write, he will squeeze the pen head 4 to drive the reset spring 305 to squeeze and contact the pressure-sensing capacitor 304 above, and then use this method to prevent the device from being accidentally touched, thereby improving the practicality of the device.

[0030] Among them, there are multiple anti-slip grooves on the surface of the squeezing block 202, and the multiple anti-slip grooves are equidistantly distributed. During use, the user presses the squeezing block 202 to make the pen tip 4 stick out of the storage block 3, and the multiple anti-slip grooves can increase the friction between the squeezing block 202 and the user's fingers, allowing the user to easily adjust and control the device.

[0031] Among them, a deceleration ring 303 is rotatably connected to the inner wall of the driving groove 302 through a ball bearing, and the deceleration ring 303 is threadedly engaged with the driving rod 402. During use, the pen head 4 drives the driving rod 402 to move upward and squeezes the reset spring 305 to complete the contact with the pressure sensing capacitor 304. At this time, when the driving rod 402 is moving upward, the deceleration ring 303 connected by thread engagement can cooperate with the driving rod 402 to rotate continuously. During the rotation process, the deceleration ring 303 can only move forward a certain distance every time the driving rod 402 rotates one circle. On the contrary, if the driving rod 402 needs to move upward, it needs to drive the deceleration ring 303 to rotate several circles, thereby limiting the speed and slowing down the driving rod 402 to prevent the driving rod 402 from moving up quickly and contacting the pressure sensing capacitor 304 when accidentally touched, thereby improving the device's anti-accidental touch capability.

[0032] Among them, the bottom of the pen tip 4 is arranged in a semicircular structure, and a protective layer made of conductive adhesive material is provided on the surface of the pen tip 4. During use, the semicircular structure and the protective layer made of conductive adhesive can prevent the pen tip 4 from being damaged by friction during use. The conductivity and wear resistance of the conductive adhesive can protect the pen tip 4 while preventing insulation from making it difficult for the pen tip 4 to perform capacitive sensing with the touch screen.

[0033] Among them, a battery 101 is provided inside the main body 1, and a push switch is provided on one side of the main body 1, and the push switch is electrically connected to the battery 101 and the pressure-sensitive capacitor 304 respectively. During use, the device is opened and closed by using the push switch, which improves the convenience of use of the device.

[0034] Example 2

[0035] Based on Example 1, the placement component includes: a plurality of support legs 102 arranged on the top of the main body 1, and the plurality of support legs 102 are arranged along the circumference of the main body 1; a pad 103 arranged on the top of the support legs 102. After use, the user can invert the device and use the support legs 102 and the pad 103 to support the main body 1 to prevent the main body 1 from tipping over and collapsing, thereby improving the practicality of the device.

[0036] Among them, a suction cup 104 is provided on the top of the cushion block 103, and both the cushion block 103 and the suction cup 104 are made of rubber material. During use, the suction cup 104 made of rubber material can adsorb the placement surface, making the placement of the main body 1 more stable and will not collapse, thereby improving the storage stability of the device.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
