And in order to meet the requirement that whether the user generates a pressing sound in the using process of the pressing pen, the selection adjustment is performed. The embodiment of the application improves the structure of the pressing pen as follows.

A plurality of guide ribs 14 are arranged on the inner wall, close to the tail part, in the pen holder 1, the guide ribs 14 extend along the length direction of the pen holder 1, and guide grooves are formed between two adjacent guide ribs 14;

the pen cap 4 comprises a cap body 41 and an adjusting component 42, wherein a driving part 40 is arranged on the cap body 41, the cap body 41 is rotatably arranged in the first mounting port 12, a second pushing part 421 is also arranged on the adjusting component 42, and the driving part 40 is abutted against the second pushing part 421;

the driving assembly comprises a sliding part 3 and a rotating part 32, wherein the sliding part 3 is of a hollow structure, a first tooth structure is arranged on the periphery of the sliding part 3, a second tooth structure is arranged on the rotating part 32, and the first tooth structure and the second tooth structure are oppositely arranged;

wherein the sliding part 3 is slidably arranged in the pen holder 1 along the guide rib 14, and the rotating part 32 can rotate in the pen holder 1 and can also slide along the guide rib 14; the sliding part 3 and the rotating part 32 are sleeved on the adjusting part 42;

the cap 41 is rotatably provided on the sliding member 3, and the driving part 40 is configured to convert the rotational movement of the cap 41 into the sliding movement of the regulating member 42 in cooperation with the second pushing part 421;

the end of the adjusting member 42 opposite to the barrel 1 is an adjusting end, and the end surface of the adjusting end is selectively protruded to the outside of the rotating member 32.

Specifically, the cap body 41 is provided in the first mounting opening 12 of the pen holder 1, and the user presses the cap body 41 to realize driving of the pen core 2 to slide in the pen holder 1. And the cap 41 is provided with an adjusting member 42, and the rotation of the cap 41 is matched with the second pushing portion 421 through the driving portion 40 to realize the sliding of the adjusting member 42 relative to the sliding member 3.

By adjusting the position of the adjustment member 42, the adjustment end of the adjustment member 42 may be extended from the rotational member 32 or the adjustment end of the adjustment member 42 may be retracted into the rotational member 32.

Wherein, when the end face of the adjusting end of the adjusting part 42 extends to the outside of the rotating part 32, the pen core 2 is in a retracted state, and the adjusting end of the adjusting part 42 is abutted against the pen core 2; when the end face of the adjustment end of the adjustment member 42 is retracted into the rotary member 32, the rotary member 32 abuts against the pen core 2 in the retracted state.

The different positions of the adjusting member 42 can realize that the user generates a pressing sound or realizes a mute pressing when pressing the cap 41. The following is a detailed description with reference to the accompanying drawings.

As shown in fig. 9 to 10, when the user operates the pressing pen to require a pressing sound, the cap 41 is rotated so that the adjustment end of the adjustment member 42 is retracted inside the rotation member 32. Taking the case that the pen core 2 of the pressing pen is in the retracted state as an initial state, when the user presses the cap 41, the cap 41 drives the sliding part 3 to slide along the guide rib 14 towards the pen head 11, meanwhile, the sliding part 3 abuts against the rotating part 32, so that the rotating part 32 also slides along the guide rib 14, and before the rotating part 32 is not separated from the guide rib 14, the rotating part 32 can only slide in the pen holder 1. The rotating part 32 directly abuts against the pen core 2 in the sliding process so as to drive the pen core 2 to slide; when the rotating member 32 is separated from the guide rib 14, the rotating member 32 can rotate, and the pen core 2 moves reversely by a short distance under the action of the spring 5, so that the rotating member 32 is driven to move reversely, and the first tooth structure and the second tooth structure are meshed to generate pressing sound. The manner of interaction between the sliding member 3 and the rotating member 32 in the pressing sound state of the pressing pen may be referred to a conventional pressing pen, and will not be described herein.

As shown in fig. 11 to 12, when the user operates the pressing pen without pressing sound, the cap 41 is rotated so that the adjustment end of the adjustment member 42 protrudes outside the rotation member 32. When the user presses the cap 41, the cap 41 drives the sliding member 3 to slide along the guide rib 14 toward the pen head 11, and at the same time, the sliding member 3 abuts against the rotating member 32, so that the rotating member 32 also slides along the guide rib 14, and before the rotating member 32 does not separate from the guide rib 14, the rotating member 32 can only slide in the pen holder 1. The rotating part 32 is not contacted with the end part of the pen core 2 in the sliding process, but the dispensing end part of the adjusting part 42 is abutted against the pen core 2 to drive the pen core 2 to slide; when the rotating part 32 is separated from the guide rib 14, the dispensing end of the adjusting part 42 is abutted against the pen core 2, so that the pen core 2 cannot reversely move for a short distance under the action of the spring 5, the rotating part 32 cannot immediately rotate when just separated from the guide rib 14, the sliding part 3 is required to continuously move, and the rotating part 32 can be driven to rotate by means of the tooth surface cooperation of the first tooth structure and the second tooth structure, so that the pressing noise generated by the reverse movement of the rotating part 32 due to the action of the spring 5 can be avoided. After the user releases his hand, the pen core 2 moves reversely under the action of the spring 5, and the pen core 2 moves reversely while abutting against the rotating member 32 and the regulating member 42, and finally, the rotating member 32 is caught on the guide rib 14 to keep the pen tip 21 exposed.

The pressing mute of the pressing pen described in the present application is merely a state representing that the pressing sound is small compared with the conventional pressing pen to achieve approximate silence in the human auditory range.

By providing the adjustment member 42 on the cap 41, the adjustment member 42 can be driven by the cap 41 to slide relative to the sliding member 3, the adjustment member 42 rotates the cap 41 according to whether the user has a pressing sound when pressing, when the user needs to mute pressing, the cap 41 drives the end face of the adjustment end of the adjustment member 42 to extend out of the rotating member 32, so that in the process of pressing the cap 41 to drive the pen core 2 to move so that the pen point 21 extends out of the pen point 11, the adjustment end of the adjustment member 42 abuts against the pen core 2, and after the rotating member 32 is separated from the guide rib 14, since the rotating member 32 does not apply an external force to the pen core 2, the rotating member 32 is prevented from reversely moving due to the external force of the pen core 2 to generate sound so as to realize mute pressing due to the action of the spring 5; on the contrary, the cap 41 rotates reversely to enable the adjusting end of the adjusting part 42 to retract into the rotating part 32, so that in the process of pushing the cap 41 to drive the pen core 2 to move and extend, the rotating part 32 is abutted against the pen core 2, after the rotating part 32 is separated from the guide rib 14, under the action of the spring 5, the pen core 2 drives the rotating part 32 to move reversely and be clamped at the end of the guide rib 14 so as to generate pushing sound, the user can adjust the pushing pen to have pushing sound or mute pushing according to the needs, and the use requirements of different users are met so as to improve the use experience of the user and the use experience of the user.
