a spring (not shown) provided in the barrel 1 and used to drive the refill 2 or the slider 32 to return;

wherein, in the process that the slider 32 drives the positioning element 33 to move towards the rotation driving part 312, the rotation driving part 312 is used for touching the positioning part 331 to drive the positioning element 33 to rotate, and the positioning matching part 313 is used for matching with the positioning part 331 to limit the pen point of the pen core 2 from extending out of the pen holder 1.

Specifically, the pen holder 1 is provided with an independent pressing positioning component 3 for positioning the pen core 2 after extending out. When the sliding member 32 moves due to external force, the positioning member 33 is driven to move together, so that the positioning portion 331 slides in the guide sliding slot 311; the positioning portion 331 slides to the rotation driving portion 312, and is abutted by the rotation driving portion 312 to enable the positioning portion 331 to rotate in the guide chute 311, and then the positioning engagement portion 313 is in contact engagement with the positioning portion 331 to position the position of the slider 32. The rotation driving portion 312 is used for driving the positioning member 33 to rotate by touching the positioning portion 331, and the positioning matching portion 313 is used for enabling the pen point of the pen core 2 to extend out of the pen holder 1 by clamping the positioning portion 331, so that the pen core 2 is kept in an extending-out state, and the writing and using requirements of a user are met. For the convenience of the user, the press-type writing utensil may be provided with a separate cap 4 provided on the slider 32.

The specific using process is as follows: when the user needs to write using the press-type writing instrument, the user presses the cap with his finger, and as shown in fig. 6, the cap moves the driving slider 32 toward the pen tip 21, and thus the positioning portion 331 moves toward the rotational driving portion 312. During the movement of the slider 32, as shown in fig. 7, the positioning portion 331 will contact the rotation driving portion 312, and the rotation driving portion 312 will drive the positioning portion 331 to rotate, so that the positioning portion 331 rotates toward the positioning engagement portion 313. After the user releases his hand, as shown in fig. 8, under the action of the spring, the sliding member 32 will move in the opposite direction, and at the same time, the positioning portion 331 will be driven to slide in the guiding sliding slot 311, and the positioning portion 331 will be limited by the positioning matching portion 313, so that the positioning portion 331 and the positioning matching portion 313 are clamped together; at this time, the pen point 21 of the pen core 2 is exposed outside the pen holder 1, so that the user can write conveniently.
