In addition, since the space of the accommodating cavity 110 inside the barrel 100 is limited, other structures are provided in the accommodating cavity 110 to limit the moving direction of the rack 430, which may increase the processing difficulty of the barrel 100 and increase the cost. Therefore, the fixing seat 440 is separately machined, which not only facilitates the reduction of the machining difficulty, but also reduces the cost. Moreover, the connection mode between the fixing seat 440 and the pen shaft 100 may be implemented by gluing or interference fit, which is not specifically limited in this application.

In addition, in order to prevent the pen cap 200 and the rotating rod 410 from moving from the second opening 130 to the outside of the accommodating cavity 110 along the central line of the rotating rod 410, as shown in fig. 11, the rotating rod 410 provided by the present application is disposed in the accommodating groove 441, as shown in fig. 12, the rotating rod 410 is provided with a first protrusion 411, and the first protrusion 411 and the rotating rod 410 are connected into an integral structure; as shown in fig. 13, the inner wall of the accommodating groove 441 is provided with a first limiting groove 442, and along a plane perpendicular to the rotating rod 410, the cross section of the first limiting groove 442 is arc-shaped, and the center of the arc is located on the central line of the rotating rod 410, that is, the groove wall of the first limiting groove 442 is an arc surface; as shown in fig. 14, the first protrusion 411 is located in the first position-limiting groove 442. Thus, the first protrusion 411 can be limited to move along the central line direction of the rotation rod 410 by the first limiting groove 442, and the first protrusion 411 can rotate along the arc surface of the first limiting groove 442, so that the first protrusion 411 is engaged with the first limiting groove 442, the rotation rod 410 and the pen cap 200 can be prevented from extending out of the accommodating cavity 110 from the second opening 130 along the central line direction of the pen holder 100, and the pen cap 200 and the rotation rod 410 can be prevented from being separated from the pen holder 100.

In some embodiments, as shown in fig. 15, along a plane perpendicular to the rotating rod 410, the cross-sectional edge of the first protrusion 411 is an arc, and the arc is the same as the arc formed by the cross-section of the first limiting groove 442, and two opposite sidewalls of the first protrusion 411 perpendicular to the rotating rod 410 are respectively abutted against two opposite sidewalls of the first limiting groove 442. Because the arc line that the cross-section border of first arch 411 formed is the same with the arc radian that the cross-section of first spacing groove 442 formed, the arc lateral wall of first arch 411 and the arc cell wall of first spacing groove 442 laminate each other promptly. Thus, when the rotating rod 410 rotates, the first protrusion 411 can be driven to rotate around the arc center of the circle in the first limiting groove 442. Moreover, because the two opposite side walls of the first limiting groove 442 abut against the two opposite side walls of the first protrusion 411, the first protrusion 411 and the rotating rod 410 can be prevented from moving axially, so that the pen cap 200 is prevented from shaking relative to the pen holder 100 when the user rotates the pen cap 200, and the user experience can be improved.

In order to enable the gear 420 to rotate relative to the fixing base 440, as shown in fig. 16, the stylus pen 10 provided by the present application further includes a positioning shaft 450, the positioning shaft 450 is disposed on the sidewall of the accommodating groove 441, the positioning shaft 450 is perpendicular to the rotating rod 410, the positioning shaft 450 is perpendicular to the length direction of the rack 430, and the gear 420 is sleeved on the positioning shaft 450. Thus, the gear 420 can be rotated relative to the fixing base 440 by the positioning shaft 450.

Moreover, since the axis of the positioning shaft 450 is perpendicular to both the rotating rod 410 and the rack 430, the gear 420 can ensure that the rotation of the rotating rod 410 can be converted into the linear motion of the rack 430, i.e., the rotational motion of the pen cap 200 can be converted into the linear motion of the pen clip 300, so as to extend or retract the pen clip 300 into or from the accommodating cavity 110.

To prevent the gear 420 from moving axially along the positioning shaft 450 during rotation, the gear 420 is separated from the rotating shaft 410 and the rack gear 430. As shown in fig. 17, the positioning shaft 450 provided by the present application includes a shaft 451 and a limiting block 452, a first end of the shaft 451 is fixedly connected to a sidewall of the receiving groove 441, and the rack 430 is sleeved on the shaft 451. As shown in FIG. 18, the stop block 452 is secured to the second end of the shaft 451 and abuts a side wall of the gear 420. In this way, the stopper 452 can prevent the gear 420 from moving in the axial direction, so as to prevent the gear 420 from being separated from the rotating rod 410 and the rack 430, and ensure that the gear 420 is normally engaged with the rotating rod 410 and the rack 430.

It should be noted that the shape of the stopper 452 is not exclusive, for example, the stopper 452 may be a cylinder, that is, the radial section of the shaft 451 of the stopper 452 is circular, the axis of the cylinder coincides with the axis of the shaft 451, and the diameter of the cylinder is greater than the diameter of the shaft 451, so that the end surface of the cylinder can abut against the sidewall of the gear 420; the stopper 452 may be a rectangular parallelepiped, that is, the stopper 452 has a rectangular cross section along the radial direction of the shaft 451, and the area of the rectangular cross section is larger than that of the shaft 451, so that the side wall of the rectangular parallelepiped facing the gear 420 can abut against the side wall of the gear 420. Therefore, the present application is not limited to the specific shape of the stopper 452.

On the basis, as shown in fig. 19, the pen clip 300 provided by the present application includes a pen clip body 310 and an abutting portion 320, one end of the abutting portion 320 close to the pen cap 200 is connected with the pen clip body 310 to form an integral structure, and a gap is formed between the pen clip body 310 and the abutting portion 320; as shown in fig. 20, the abutting portion 320 is connected to the rack 430 away from the sidewall of the clip body 310, and when the clip body 310 extends out of the accommodating cavity 110, the surface of the abutting portion 320 facing the clip body 310 is flush with the outer surface of the pen barrel 100. Thus, when the clip body 310 extends out of the accommodating cavity 110, the abutting portion 320 is flush with the outer surface of the pen holder 100, and when the user uses the clip 300 to clamp the stylus pen 10, the clip body 310 and the abutting portion 320 can clamp both sides of an object with a certain thickness, so that the clamping force of the clip 300 can be prevented from being transmitted to the connection between the clip 300 and the rack 430, and the connection structure between the clip 300 and the rack 430 can be prevented from being separated from each other and damaged.

In addition, because a gap is formed between the clip body 310 and the abutting portion 320, when the clip body 310 and the abutting portion 320 are clamped on an object with a certain thickness, the stress of the clip body 310 can be reduced, so as to avoid the occurrence of breaking and damage of the clip body 310 due to an excessive stress of the clip body 310, which is beneficial to prolonging the service life of the clip 300.

Because of this, there is a gap between the clip body 310 and the abutment 320, when the clip 300 is not clamped on any object and the clip body 310 is forced close to the abutment 320, there is a risk of damaging the clip body 310. Therefore, as shown in fig. 21, the clip 300 further includes an abutting protrusion 330, the abutting protrusion 330 is disposed at one end of the clip body 310 away from the cap 200, and the abutting protrusion 330 abuts against the abutting portion 320. Thus, when the clip body 310 is forced to approach the abutting portion 320, the abutting protrusion 330 abuts against the abutting portion 320, so as to transmit the external force to the abutting portion 320, thereby reducing the force applied to the clip body 310, reducing the probability of damage to the clip body 310 due to the force applied thereto, and further prolonging the service life of the clip 300.

In some embodiments, as shown in fig. 22, the clip 300 further includes a connecting protrusion 340, the connecting protrusion 340 is disposed on a sidewall of the abutting portion 320 facing the rack 430; as shown in fig. 23, a groove 431 is opened on an end surface of the rack 430 facing the coupling protrusion 340, and as shown in fig. 24, the coupling protrusion 340 is inserted into the groove 431 and fixedly coupled. By inserting the connecting protrusion 340 into the groove 431 and fixedly connecting the two, the connecting area between the connecting protrusion 340 and the rack 430 can be increased, so that the connecting strength between the two can be improved, and the pen clip 300 and the rack 430 can be prevented from being separated from each other.

After the connecting protrusion 340 is inserted into the groove 431 of the rack 430, the connecting protrusion and the groove can be fixedly connected through interference fit or can be fixedly connected through gluing. Therefore, the present application is not particularly limited thereto.

In some embodiments, as shown in fig. 25, the clip 300 further includes two elastic arms 350, the two elastic arms 350 are disposed on the sidewall of the abutting portion 320 facing the rack 430, the two elastic arms 350 are disposed opposite to each other, and one end of the rack 430 close to the abutting portion 320 is clamped between the two elastic arms 350. Therefore, the rack 430 is clamped through the elastic force generated by the two elastic arms 350 after being stressed, the detachable connection between the rack 430 and the pen clip 300 is realized, the pen clip 300 or the rack 430 is convenient to replace, and the maintenance difficulty and cost are reduced.

It should be noted that the two connecting structures for fixing the pen clip 300 and the rack 430 may be used separately or in combination. Specifically, as shown in fig. 26, a connecting projection 340 and two elastic arms 350 are provided on a side wall of the abutting portion 320 facing the rack 430, the connecting projection 340 being provided between the two elastic arms 350; the end surface of the rack 430 facing the abutting portion 320 is provided with a groove 431, the connecting protrusion 340 is inserted into the groove 431 and fixedly connected, and one end of the rack 430 close to the abutting portion 320 is clamped between the two elastic arms 350. Therefore, the connecting protrusion 340 is fixedly connected with the inner wall of the groove 431, and the elastic arm 350 clamps the rack 430, so that the connecting strength between the connecting protrusion 340 and the inner wall of the groove 431 can be increased, and the connecting stability between the pen holder 300 and the rack 430 is further improved.

On this basis, in order to improve the rotating feel of the pen cap 200 when a user rotates the pen cap 200, as shown in fig. 27, the pen cap 200 provided by the present application includes a first portion 210 and a second portion 220, as shown in fig. 28, the first portion 210 is snapped on the second opening 130 and is connected with the second portion 220 into an integral structure, and the second portion 220 extends into the accommodating cavity 110 from the second opening 130. As shown in fig. 29, the stylus pen 10 further includes a first position-limiting portion 230 disposed on the second portion 230, and a second position-limiting portion 140 disposed on the inner wall of the accommodating cavity 110 as shown in fig. 30, wherein the first position-limiting portion 230 and the second position-limiting portion 140 are engaged with each other, so that the pen cap 200 can rotate between the first position and the second position. As shown in fig. 31, with the pen end cap 200 in the first position, the pen clip body 310 extends out of the accommodating cavity 110; as shown in fig. 32, with the pen cap 200 in the second position, the pen clip body 310 is retracted into the receiving cavity 110. Therefore, the first limiting part 230 and the second limiting part 140 are matched with each other, so that the rotation angle of the pen cap 200 can be limited, and the pen cap 200 can rotate between the first position and the second position. Therefore, when the user uses the pen cap 200, the user only needs to rotate the pen cap 200, when the pen cap 200 rotates to two limit positions, that is, the pen clip 300 is shown to be extended out or retracted into the accommodating cavity 110, the user does not need to pay attention to whether the pen clip 300 extends out of the accommodating cavity 110 in real time, and the use is more convenient.

In some embodiments, as shown in fig. 33, the first position-limiting portion 230 includes a second protrusion 230a, and the second position-limiting portion 140 includes a second position-limiting groove 140 a. The second limiting groove 140a extends around the rotation axis of the pen cap 200, and the second protrusion 230a is disposed in the second limiting groove 140 a. As shown in fig. 34, when the pen cap 200 is located at the first position, the second protrusion 230a abuts against the first end of the second limiting groove 140 a; as shown in fig. 35, when the pen end cap 200 is located at the second position, the second protrusion 230a abuts against the second end of the second limiting groove 140 a. That is, the second limiting groove 140a limits the rotation range of the pen cap 200, when the second protrusion 230a is located at two end positions of the second limiting groove 140a, the inner wall of the second limiting groove 140a prevents the second protrusion 230a from continuing to rotate, that is, the pen cap 200 cannot continue to rotate, and the second protrusion 230a is located at two ends of the second limiting groove 140a, that is, the pen cap 200 is located at the first position and the second position, respectively. Therefore, when the user uses the pen cap 200, the user only needs to rotate, and when the user cannot rotate the pen cap, the user indicates that the pen clip 300 extends out of or retracts into the accommodating cavity 110, which is beneficial to improving the user experience.

Specifically, when the pen cap 200 is located at the first position, that is, the second protrusion 230a abuts against the first end of the second limiting groove 140a (i.e., the position shown in fig. 34), the pen clip body 310 is located outside the accommodating cavity 110 (as shown in fig. 31), at this time, as shown in fig. 36, a user rotates the pen cap 200 along the first direction (a direction in the figure), the pen cap 200 drives the rotating rod 410 to rotate along the a direction, at this time, the rotating rod 410 drives the gear 420 to rotate (b direction in the figure), and the gear 420 drives the rack 430 to move towards the direction (c direction in the figure) of withdrawing the accommodating cavity 110, so as to drive the pen clip body 310 to move towards the accommodating cavity 110. When the second protrusion 230a abuts against the second end of the second limiting groove 140a (as shown in fig. 35), the user cannot rotate the pen cap 200 any more, and at this time, the pen clip body 310 is fully retracted into the accommodating cavity 110 (as shown in fig. 32). Then, when the user needs to extend the pen clip body 310 out of the accommodating cavity 110, the pen cap 200 is rotated in the opposite direction of the first direction, and when the second protrusion 230a abuts against the first end of the second limiting groove 140a again, the pen cap 200 cannot rotate in the opposite direction of the first direction, and at this time, the pen clip body 310 extends out of the accommodating cavity 110.

It should be noted that, the above description is given by taking an example that the first position-limiting portion 230 includes the second protrusion 230a, and the second position-limiting portion 140 includes the second position-limiting groove 140a, that is, the second protrusion 230a is disposed on the second portion 220 of the pen cap 200, and the second position-limiting groove 140a is disposed on the inner wall of the accommodating cavity 110. Meanwhile, the first position-limiting portion 230 may include a second position-limiting groove 140a, and the second position-limiting portion 140 includes a second protrusion 230a, as shown in fig. 37, the second protrusion 230a is disposed on the inner wall of the accommodating groove 441, and the second position-limiting groove 140a is opened on the second portion 220 of the pen cap 200. The specific working process is the same as the structure, and repeated description is not provided herein.

In some embodiments, as shown in fig. 38, the first position-limiting portion 230 includes a third protrusion 230b, and the second position-limiting portion 140 includes a third position-limiting groove 140b and a fourth position-limiting groove 140 c. The third limiting groove 140b and the fourth limiting groove 140c are distributed around the rotation axis of the pen cap 200; as shown in fig. 38, when the pen cap 200 is located at the first position, the third protrusion 230b is located in the third limiting groove 140 b; as shown in fig. 39, when the pen cap 200 is located at the second position, the third protrusion 230b is located in the fourth limiting groove 140 c. That is, the third protrusion 230b slides into the third limiting groove 140b or the fourth limiting groove 140c to limit the rotation range of the pen cap 200, and when the user rotates, the third protrusion 230b slides over the edge of the third limiting groove 140b or the fourth limiting groove 140c, an obvious pause feeling is generated, so that the user can feel that the third protrusion 230b slides into the third limiting groove 140b or the fourth limiting groove 140c, that is, the pen cap 200 is in the first position or the second position. Therefore, when a user rotates the pen cap 200, the user feels a distinct setback, that is, the pen clip 300 is extended out of or retracted into the accommodating cavity 110, which is beneficial to improving the user experience.

In addition, the movement of the push-pull assembly 400 during the rotation of the third protrusion 230b between the third stopper groove 140b and the fourth stopper groove 140c is the same as that described above, and thus, a description thereof will not be repeated.

It should be noted that, the above description is made by taking an example that the first limiting portion 230 includes the third protrusion 230b, and the second limiting portion 140 includes the third limiting groove 140b and the fourth limiting groove 140c, that is, the third protrusion 230b is disposed on the second portion 220 of the pen cap 200, and the third limiting groove 140b and the fourth limiting groove 140c are disposed on the inner wall of the accommodating cavity 110. Meanwhile, the first position-limiting portion 230 may include a third position-limiting groove 140b and a fourth position-limiting groove 140c, the second position-limiting portion 140 includes a third protrusion 230b, that is, as shown in fig. 40, the third protrusion 230b is disposed on the inner wall of the receiving groove 441, and the third position-limiting groove 140b and the fourth position-limiting groove 140c are opened on the second portion 220 of the pen cap 200. The specific working process is the same as the structure, and repeated description is not provided herein.

In addition, in order to ensure that the third protrusion 230b can smoothly enter the third stopper groove 140b or the fourth stopper groove 140c, as shown in fig. 40, the cross-sectional edge of the third protrusion 230b and the cross-sections of the third stopper groove 140b and the fourth stopper groove 140c are circular arcs in a direction perpendicular to the axis of the barrel 100, and the length of the circular arc formed by the cross-sectional edge of the third protrusion 230b is smaller than the length of the circular arc formed by the cross-sections of the third stopper groove 140b and the fourth stopper groove 140 c. That is, the side wall of the third protrusion 230b is an arc surface, and the inner walls of the third limiting groove 140b and the fourth limiting groove 140c are also arc surfaces, so that the third protrusion 230b can be ensured to slide into the third limiting groove 140b or the fourth limiting groove 140 c. Therefore, when the third protrusion 230b slides out of the third limiting groove 140b or the fourth limiting groove 140c, the arc surface can play a role in guiding, so that the third protrusion 230b can smoothly slide in or slide out, the third limiting groove 140b is prevented from being clamped into the third limiting groove 140b or the fourth limiting groove 140c, and the pen cap 200 can normally rotate.

The length and the radian of the arc formed by the cross section of the third limiting groove 140b and the arc formed by the fourth limiting groove 140c may be the same or different. Compare in the two inequality circumstances, all set up the length and the radian of third spacing groove 140b and fourth spacing groove 140c to the same structure, be favorable to reducing the processing degree of difficulty to improve machining efficiency.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
