[0021] The utility model is described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 3As shown, a rotating and telescopic structure of a touch pen of the present invention comprises a pen body 3, a first shell 1 and a second shell 2 movably arranged on the pen body 3, a rotating shaft assembly 4 arranged on the pen body 3, and a first transmission member 5 and a second transmission member 6 respectively arranged on the first shell 1 and the second shell 2 and used in conjunction with the rotating shaft assembly 4. The pen body 3 is connected to the first transmission member 5 and the second transmission member 6 via the rotating shaft assembly 4 so that the first shell 1 and the second shell 2 are moved closer to or away from the pen body 3.

[0023] When in use, the shaft assembly 4 is rotated in a clockwise or counterclockwise direction, and the shaft assembly 4 is used to be connected with the first transmission member 5 and the second transmission member 6 to make the first shell 1 and the second shell 2 close to or away from the pen body 3, so as to adjust the outer diameter of the first shell 1 and the second shell 2 relative to the pen body 3. On the one hand, by adjusting to increase the outer diameter of the first shell 1 and the second shell 2 relative to the pen body 3, it is convenient for the user to hold and use it better, and the convenience of use is improved. On the other hand, by adjusting to reduce the outer diameter of the first shell 1 and the second shell 2 relative to the pen body 3, it is convenient to insert the stylus into the slot of the electronic device, so that the outer wall of the first shell 1 and the second shell 2 better fits the inner wall of the slot, so that the stylus is not easy to loosen and fall off from the electronic device, meeting the need of carrying it with you. The utility model flexibly adjusts the outer diameter of the stylus by rotating, which is convenient for the user to hold and use, and is also convenient to carry and use, and has good convenience of use.

[0024] The shaft assembly 4 of this embodiment includes a barrel 41, a fin group 42 disposed on the barrel 41, and a shaft 43 disposed on the fin group 42. The shaft 43 is rotatably disposed in the fin group 42, and the outer wall of the shaft 43 is in conflict with the inner wall of the fin group 42. A gear 44 is disposed at one end of the shaft 43 away from the fin group 42. Specifically, the fin group 42 includes a plurality of fins stacked neatly. The fin group 42 is placed in the barrel 41, and the shaft 43 is rotatably disposed in the fin group 42, so that the outer wall of the shaft 43 is in conflict with the inner wall of the plurality of fins stacked neatly, which can provide a large friction resistance, so that the shaft 43 can keep its position fixed no matter how it rotates to any angle, thereby realizing the transmission connection between the shaft 43 and the first transmission member 5 and the second transmission member 6 by the gear 44, and fixing the position of the first shell 1 and the second shell 2 relative to the pen body 3, so that the position will not change easily.

[0025] The first transmission member 5 of this embodiment includes a first rack 51 and a first limit block 52 arranged on the first rack 51, one end of the first rack 51 is connected to the first shell 1, the other end of the first rack 51 is connected to the first limit block 52, the first rack 51 and the first limit block 52 are vertically arranged in an L shape, the second transmission member 6 includes a second rack 61 and a second limit block 62 arranged on the second rack 61, one end of the second rack 61 is connected to the second shell 2, the other end of the second rack 61 is connected to the second limit block 62, the second rack 61 and the second limit block 62 are vertically arranged in an L shape, the first rack 51 and the second rack 61 are respectively located on both sides of the gear 44, and the first rack 51 and the second rack 61 are meshed with the gear 44. Specifically, the first rack 51 and the second rack 61 are respectively located on both sides of the gear 44, and the gear 44 is engaged with the first rack 51 and the second rack 61 for transmission. When the first limit block 52 and the second limit block 62 are blocked and abutted against the upper and lower outer walls of the gear 44, the maximum outer diameter of the first shell 1 and the second shell 2 relative to the pen body 3 can be limited, which plays a good limiting role, avoids the excessive separation of the first shell 1 and the second shell 2 from the pen body 3 and causes accidental falling off, and improves the safety performance of use.

[0026] In this embodiment, two rotating shaft assemblies 4 are provided, and the two rotating shaft assemblies 4 are respectively provided at the two ends of the pen body 3. Both ends of the pen body 3 are provided with receiving grooves 31. The two rotating shaft assemblies 4 are respectively provided in the two receiving grooves 31. One rotating shaft assembly 4 is provided with a pen cap 7, and the other rotating shaft assembly 4 is provided with a pen tip 8. Specifically, the two rotating shaft assemblies 4 are respectively provided in the two receiving grooves 31, so that the two rotating shaft assemblies 4 are stably installed at the two ends of the pen body 3, and one rotating shaft assembly 4 is provided with a pen cap 7, and the other rotating shaft assembly 4 is provided with a pen tip 8. When using the touch pen, the user holds the pen tip 8 with one hand and the pen cap 7 with the other hand, and drives the shaft body 43 to be connected with the first transmission member 5 and the second transmission member 6 by rotating the pen cap 7, so that the first shell 1 and the second shell 2 are close to or away from the pen body 3, thereby adjusting and changing the outer diameter between the first shell 1 and the second shell 2.

[0027] The first shell 1 and the second shell 2 of this embodiment are in an arc-shaped semicircle, and the first shell 1 and the second shell 2 are connected in a cylindrical shape. Specifically, the first shell 1 and the second shell 2 are connected in a cylindrical shape, which conforms to the structural design of the pen and is convenient for the user to hold and use.
