[0029] See also Figures 1 to 3This embodiment provides a touch pen with a switching function, including a pen barrel 1, a pen core module 2, a transmission sleeve 3 and a tail cover 4.

[0030] The refill module 2 provides all the functions of an electronic stylus, such as writing and erasing, and features buttons for switching between various output modes. Both the refill module 2 and the transmission sleeve are located within the pen barrel 1, with the tail cap 4 located at the top of the barrel 1 (the "top" in this context refers to the end away from the tip of the refill module 2). The top of the transmission sleeve 3 is fixedly connected to the tail cap 4, allowing the transmission sleeve 3 and tail cap 4 to rotate together relative to the pen barrel 1.

[0031] In this embodiment, please refer to Figure 4 A fixing section 31 is provided at the top of the transmission sleeve 3. The cross section of the fixing section 31 is D-shaped. The tail cover 4 has an installation cavity 41 inside. The fixing section 31 is inserted into the installation cavity 41, and the shape of the installation cavity 41 matches the shape of the fixing section 31.

[0032] The bottom end of the transmission sleeve 3 is sleeved on the outer periphery of the refill module 2. The transmission sleeve 3 can rotate relative to the refill module 2. That is, when the tail cover 4 is rotated, the tail cover 4 and the transmission sleeve 3 rotate together, while the pen barrel 1 and the refill module 2 are fixed.

[0033] See also Figure 5 and Figure 6 , the transmission sleeve 3 is provided with an elastic arm 32 at the position corresponding to the button, and an inner convex point 321 is provided on the inner side of the elastic arm 32; when the transmission sleeve 3 is rotated to the position corresponding to the elastic arm 32 and the button (such as Figure 7 As shown), the inner protrusion 321 on the elastic arm 32 can push against the button to achieve function switching.

[0034] Because the tail cap 4 for switching functions is a rotating structure and is located away from the user's grip on the pen barrel 1, accidental touches are less likely to occur. Furthermore, compared to existing methods of providing buttons on the outer periphery of the pen barrel, the tail cap 4 of this embodiment is located at the top of the pen barrel 1 and does not protrude from the outer surface of the pen barrel 1, which improves the product's aesthetics.

[0035] In some preferred embodiments, the button is exposed on the outer surface of the refill module 2 so that the inner protrusion 321 can contact the button more directly, thereby avoiding the problem of poor contact resulting in insufficient force to press the button and causing function switching failure.

[0036] In some preferred embodiments, Figure 5 and Figure 6As shown, an outer convex point 322 is provided on the outer surface of the elastic arm 32, and the outer convex point 322 abuts against the inner wall of the pen holder 1. Since the inner wall of the pen holder 1 abuts against the outer convex point 322, the inner wall of the pen holder 1 can exert an inward force on the elastic arm 32, causing the elastic arm 32 and the inner convex point 321 to deviate toward the key, thereby ensuring the pressing force and pressing space of the inner convex point 321 on the key.

[0037] In this embodiment, the pen barrel 1 includes an upper pen barrel 11 and a lower pen barrel 12. The tip of the pen core module 2 extends out of the lower end of the lower pen barrel 12. The top end of the lower pen barrel 12 is embedded in the upper pen barrel 11 and is bonded and fixed to the inner wall of the upper pen barrel 11. Figure 8 A positioning protrusion 121 is provided on the outer periphery of the lower pen barrel 12, and a positioning groove 111 is provided on the inner wall of the lower end of the upper pen barrel 11. The positioning protrusion 121 is embedded in the positioning groove 111. By providing the above-mentioned positioning structure, it is convenient for the upper pen barrel 11 and the lower pen barrel 12 to be quickly positioned and docked when assembled, and it can also prevent the upper pen barrel 11 and the lower pen barrel 12 from rotating relative to each other.

[0038] See also Figure 9 The outer periphery of the transmission sleeve 3 is provided with a raised stopper 33, and the lower pen barrel 12 is provided with a stopper groove 122. The width of the stopper groove 122 is greater than the width of the stopper 33. When the transmission sleeve 3 rotates, the stopper 33 can move within the stopper groove 122. By designing the above-mentioned stopper structure, the rotation range of the tail cover 4 can be limited, which is not conducive to helping the user determine whether it is rotated in place, thereby improving the operation accuracy.

[0039] Please also read Figure 5 and Figure 6 The outer periphery of the transmission sleeve 3 is provided with at least one annular abutment portion 34 protruding from the outer periphery along its axial direction. The annular abutment portion 34 contacts the inner wall of the pen barrel 1. The annular abutment portion 34 supports the transmission sleeve 3 in the radial direction of the pen, preventing the transmission sleeve 3 from shaking during rotation and ensuring the stability of the elastic arm 32 in the radial direction.

[0040] Furthermore, if Figure 1 As shown, in order to prevent the electric shock pen from rolling accidentally, a planar anti-rolling structure 5 is provided on the outer periphery of the pen barrel 1 and the outer periphery of the tail cover 4 in this embodiment.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
