a pressing assembly 5, the pressing assembly 5 comprising a sliding member 51 and a rotating member 52, the sliding member 51 being provided with a first tooth structure and the rotating member 52 being provided with a second tooth structure, the first tooth structure being arranged opposite to the second tooth structure;

wherein the sliding part 51 is slidably arranged in the pen holder 1 along the guide rib 13, and the rotating part 52 can rotate in the pen holder 1 and can also slide along the guide rib 13; the sliding part 51 and the rotating part 52 are sleeved on the adjusting part 3;

the cap 4 is rotatably provided on the sliding member 51, and the driving part 41 is configured to convert the rotational movement of the cap 4 into the sliding movement of the regulating member 3 in cooperation with the pushing part 31;

the end of the adjusting part 3 opposite to the pen holder 1 is an adjusting end, and the end surface of the adjusting end selectively protrudes to the outside of the rotating part 52.

Specifically, the cap assembly provided at the mounting opening 12 of the pen holder 1, the cap 4 is provided in the mounting opening 12, and the user presses the cap 4 to realize driving of the pen core 2 to slide in the pen holder 1. And the cap body 4 is provided with the adjusting member 3 therein, and the rotation of the cap body 4 is coordinated with the pushing portion 31 through the driving portion 41 to realize the sliding of the adjusting member 3 with respect to the sliding member 51.

By adjusting the position of the adjustment member 3, the adjustment end of the adjustment member 3 can be extended from the rotation member 52 or the adjustment end of the adjustment member 3 can be retracted into the rotation member 52.

Wherein, when the end face of the adjusting end of the adjusting part 3 extends out of the rotating part 52, the pen core 2 is in a retracted state, and the adjusting end of the adjusting part 3 is abutted against the pen core 2; when the end face of the adjustment end of the adjustment member 3 is retracted into the rotary member 52, the rotary member 52 abuts against the pen core 2 in the retracted state.

In addition, for the barrel 1, it may be in a split structure for convenience of assembly, that is, the barrel includes a first rod body (not marked) and a second rod body (not marked), which are detachably connected together. For example: the end parts of the first rod body and the second rod body which are connected and matched are connected by adopting threaded connection or clamping fit. The head of the first rod body is provided with a pen point, the tail of the second rod body is provided with a mounting opening, and a plurality of guide ribs are arranged on the inner wall, close to the tail, in the second rod body.

The different positions of the adjusting part 3 can realize that a user generates a pressing sound or realizes mute pressing when pressing the cap body 4. The following is a detailed description with reference to the accompanying drawings.

As shown in fig. 3 to 5, when the user operates the pressing pen to require a pressing sound, the cap 4 is rotated so that the adjustment end of the adjustment member 3 is retracted inside the rotation member 52. 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 body 4, the cap body 4 drives the sliding part 51 to slide along the guide rib 13 towards the pen head 11, meanwhile, the sliding part 51 abuts against the rotating part 52, so that the rotating part 52 also slides along the guide rib 13, and before the rotating part 52 is not separated from the guide rib 13, the rotating part 52 can only slide in the pen holder 1. The rotating part 52 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 52 is separated from the guide rib 13, the rotating member 52 can rotate, and the pen core 2 moves reversely by a short distance under the action of the spring 6, so that the rotating member 52 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 51 and the rotating member 52 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. 6 to 8, when the user operates the pressing pen without a pressing sound, the cap 4 is rotated so that the adjustment end of the adjustment member 3 protrudes outside the rotation member 52. When the user presses the cap 4, the cap 4 drives the sliding member 51 to slide along the guide rib 13 toward the pen head 11, and at the same time, the sliding member 51 abuts against the rotating member 52, so that the rotating member 52 also slides along the guide rib 13, and before the rotating member 52 does not separate from the guide rib 13, the rotating member 52 can only slide in the pen holder 1. The rotating part 52 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 3 is abutted against the pen core 2 to drive the pen core 2 to slide; when the rotating part 52 is separated from the guide rib 13, the dispensing end of the adjusting part 3 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 6, the rotating part 52 cannot immediately rotate when just separated from the guide rib 13, the sliding part 51 is required to continuously move, and the rotating part 52 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 52 due to the action of the spring 6 can be avoided. After the user releases his hand, the pen core 2 moves reversely under the action of the spring 6, and the pen core 2 moves reversely against the rotating member 52 and the adjusting member 3 at the same time, and finally, the rotating member 52 is caught on the guide rib 13 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 arranging the adjusting part 3 on the cap body 4, the adjusting part 3 can be driven by the cap body 4 to slide relative to the sliding part 51, the adjusting part 3 rotates the cap body 4 according to whether the user has a pressing sound when pressing, when the user needs to mute pressing, the cap body 4 drives the end face of the adjusting end part of the adjusting part 3 to extend out of the rotating part 52, thus, in the process of pressing the cap body 4 to drive the pen core 2 to move so that the pen point 21 extends out of the pen point 11, the adjusting end part of the adjusting part 3 is abutted against the pen core 2, and after the rotating part 52 is separated from the guide rib 13, the rotating part 52 does not apply an external force to the pen core 2, so that the rotating part 52 can be prevented from generating sound due to the reverse movement of the external force of the pen core 2 due to the action of the spring 6, and mute pressing can be realized; on the contrary, the cap body 4 reversely rotates to enable the adjusting end part of the adjusting part 3 to retract into the rotating part 52, so that in the process of driving the pen core 2 to move and extend by pressing the cap body 4, the rotating part 52 is abutted against the pen core 2, after the rotating part 52 is separated from the guide rib 13, under the action of the spring 6, the pen core 2 drives the rotating part 52 to reversely move and be clamped at the end part of the guide rib 13 so as to generate pressing sound, the purpose that a user adjusts the pressing pen to have pressing sound or mute pressing according to the needs is achieved, 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.
