It is understood that in other embodiments, the tip sleeve 312 is provided with a plurality of guide blocks along the length direction, and the locking sleeve 355 is provided with a plurality of guide slots corresponding to the guide blocks.

Referring to fig. 5, the locking sleeve 355 is provided with a protrusion 3553 adjacent to the inner wall of the damping member 311 for catching the locking spring 3513, thereby achieving that the locking spring 3513 is sandwiched between the stop ring 3515 adjacent to the barrel 33 and the protrusion 3553. The inner wall of the locking sleeve 355 is provided with a substantially conical sliding guide surface 3554 at an end thereof adjacent to the damping member 311, so that the locking member 351 can provide a space for the first locking member 3511 and the second locking member 3512 to be opened when moving toward the end of the damping member 311. The locking sleeve 355 is provided with a protrusion 3555 adjacent to the inner wall of the unlocking member 353 for catching the washer 354, thereby achieving that the spring 3533 is sandwiched between the washer 354 and the stop ring 3532 of the unlocking member 353.

The coring control device 35 further includes a spring 352 sleeved on the damping member 311 and a locking member 356 fixedly connected to the locking sleeve 355.

The inner wall of the locking member 356 is provided with internal threads 3561 that engage external threads 3551 of the locking sleeve 355. The locking member 356 axially opens an opening 3562 through which the barrel 33 passes. The diameter of the opening 3562 is smaller than the outer diameter of the stop ring 3532 of the unlocking member 353 so that the unlocking member 353 is retained in the opening 362.

It will be appreciated that in this embodiment, the barrel 33, the locking member 351, the unlocking member 353, the locking sleeve 355 and the locking member 356 are made of conductive material or the surface of the body of each member is coated with conductive material to achieve conductive communication between the pencil lead 20 and the barrel 33.

Referring to fig. 1 to 6, in assembly, the spring 352 is sleeved on the damping member 311, and the damping member 311 is sleeved on the tip sleeve 312, so that the damping member 311 is exposed from the tip sleeve 312. The locking sleeve 355 is connected to the tip sleeve 312, that is, the guide block 3552 of the locking sleeve 355 penetrates through the guide slot 3122 of the tip sleeve 312, the end of the locking sleeve 355 abuts against the spring 352, and the guide block 3552 of the locking sleeve 355 is located at the top of the guide slot 3122 under the reaction force of the spring 352. The first and second latches 3511 and 3512 are sleeved with a latch spring 3513, so that the first and second latches 3511 and 3512 are engaged with each other. One end of the locking member 351 close to the damping member 311 is accommodated in the locking sleeve 355, and one end of the locking member 351 far from the damping member 311 is clamped in the through hole 3530 of the unlocking member 353. It will be appreciated that the washer 354 and spring 3533 may be pre-positioned over the unlocking member 353. The internal thread 332 of the pen barrel 33 is screwed with the external thread 3531 of the unlocking member 353. Assembly of cartridge loading mechanism 30 is accomplished by passing fastener 356 through barrel 33 and locking onto locking sleeve 355.

The barrel 33 of the refill loading mechanism 30, to which the pencil refill 20 is attached, is connected to the pressure sensor 50, and at this time, the pencil refill 20 and the pressure sensor 50 are electrically connected. The first and second coupling frames 111 and 112 are engaged with each other, and the cartridge loading mechanism 30 is interposed between the first and second coupling frames 111 and 112. The circuit board 40 is mounted on the first connection frame 111. The outer barrel 12 is sleeved on the connecting frame 11, the connecting frame 11 is positioned in the outer barrel 12, the power supply 60 is arranged at the tail part of the outer barrel 12, the pen tail 14 is connected to the tail part of the outer barrel 12, and at the moment, the power supply 60 is electrically connected to the circuit board 40 through the conductive terminals. The nib 13 is attached to the head of the outer cylinder 12.

When the pencil lead 20 is to be used, the nib 13 is twisted open to separate the nib 13 from the outer barrel 12, and the lead loading mechanism 30 is removed. The lead 20 is inserted into the barrel 33 such that the lead 20 passes through the unlocking member 353 and abuts against the limit step surface 3518 of the locking member 351, i.e., the lead 20 is received in the first tensioning groove 3516. The pen tube 33 is pressed, so that the pen tube 33 drives the unlocking member 353 to slide towards the locking member 351, and the guide block 3552 of the locking sleeve 355 slides from the top end of the sliding slot 322 towards the bottom end of the sliding slot 322. At this time, the locking springs 3513, 3533 and 352 are all compressed, and the locking member 351 extends out of the locking sleeve 355 to separate the first locking member 3511 and the second locking member 3512, so that the pencil lead 20 can pass through the second tensioning groove 3517. It will be appreciated that, because the locking member 351 has a unidirectional locking function, the pencil lead 20 can continue to move forward but cannot move backward after being locked. After the barrel 33 stops being pressed, the locking springs 3513, 3533 and 352 return to the deformed state, the locking member 351 is accommodated in the locking sleeve 355, and the pencil lead 20 is locked. The pen tube 33 is pressed with a small force again, so that the pen tube 33 and the locking sleeve 355 have relative compression displacement, at this time, the locking member 351 is not pushed open, that is, the pencil lead 20 is clamped between the first locking member 3511 and the second locking member 3512, the pencil lead 20 and the locking sleeve 355 integrally move forward along the damping member 311, at this time, a certain damping force is matched between the damping member 311 and the hole shaft of the pencil lead 20, therefore, when the pen tube 33 is reset, the damping member 311 pulls the pencil lead 20 forward through the damping force between the damping member 311 and the pencil lead 20, and the pencil lead is discharged. As can be appreciated, the amount of lead coming out is the relative displacement D1 of the barrel 33 and locking sleeve 355 (i.e., the distance between the locking member 356 and the nib 312). Thereafter, the cartridge loading mechanism 30 may be mounted back into the outer barrel 12 of the stylus 200, and the pen tip 13 may be coupled to the outer barrel 12, with the damping member 311 exposed through the opening 132 of the pen tip 13.

When the pencil lead 20 is worn, the damping member 311 is pressed with a small force due to the relative fixation of the barrel 33, so that there is a relative displacement between the damping member 311 and the pencil lead 20, and at this time, the spring 352 is compressed. It will be appreciated that since the spring 352 is much smaller than the spring 3533, the locking member 351 is not pushed open, i.e., the first locking member 3511 engages the second locking member 3512, and the pencil lead 20 moves forward relative to the damping member 211. At this time, a certain damping force exists between the damping member 211 and the pencil lead 20, so when the damping member 211 is stopped being pressed, the spring 352 recovers to deform so that the damping member 211 is reset, and at this time, the damping member 211 pulls the pencil lead 20 to move forward through the damping force between the damping member 211 and the pencil lead 20, so that the pencil lead is discharged. It can be appreciated that the amount of lead out is the amount of compressive displacement of the damping member 211.

Please refer to fig. 7 to 11, which are schematic perspective views of a stylus according to a second embodiment of the present application. The structure of the stylus pen 200 provided in the second embodiment is similar to that of the stylus pen 100 provided in the first embodiment, and therefore the size, the name, the position relationship, and the like of each element included in the stylus pen 200 can be referred to the stylus pen 100, and the description thereof is omitted.
