In the process of pressure detection, in order to keep the detection result accurate, the pen point part 1-1, the connecting part 1-2 and the pressure sensing part 1-3 need to be ensured to be collinear, so that the overall pressure is more concentrated. In the embodiment, the collinear connection between the pen point part 1-1 and the bearing cylinder 1-2-1 is ensured through the connection mode that the pen point part 1-1 is inserted into the bearing cylinder 1-2-1; the collineation between the connecting cylinder 1-2-2 and the bearing cylinder 1-2-1 is ensured by sleeving the bearing cylinder 1-2-1 on the connecting cylinder 1-2-2; in this way, the entire pen tip 1 is arranged collinearly from the end point of the pen tip 1-1 to the pressure sensing part 1-3.

Example 2

As shown in FIGS. 5 to 8, the present embodiment provides a pen point 1, wherein the pen point 1 comprises a pen point portion 1-1, a connecting portion 1-2 and a pressure-sensitive portion 1-3, the pen point portion 1-1 is connected to an inner frame 2 inside the pen body through the connecting portion 1-2, and the pressure-sensitive portion 1-3 is disposed on the top of the pen point portion 1-1 for detecting the pressure transmitted from the pen point portion 1-1.

Specifically, in the present embodiment, an inner frame 2 is disposed inside the pen body, a circuit board may be loaded in the inner frame 2, and related electronic elements capable of implementing the basic functions of the electronic pen are soldered on the circuit board. The pen point 1 and the inner frame 2 are connected through a connecting part 1-2. The connecting part 1-2 comprises a bearing cylinder 1-2-1 and a connecting cylinder 1-2-2. The bottom of the bearing cylinder 1-2-1 is open, the top is closed, and the whole shape is T-shaped. The top of the T-shaped bearing cylinder 1-2-1 is provided with a pressure sensing part 1-3. The connecting cylinder 1-2-2 is sleeved on the bearing cylinder 1-2-1, so that the bearing cylinder 1-2-1 can move up and down in the connecting cylinder 1-2-2. The connecting cylinder 1-2-2 is connected with an inner frame 2 in the pen body. One end of the pen point part 1-1 is inserted into the bearing cylinder 1-2-1, and the other end is exposed to the outside of the pen body.

More specifically, the side wall of the bearing cylinder 1-2-1 is provided with a clamping through hole, and the pen point part 1-1 is provided with a clamping groove. When the nib part 1-1 is inserted into the inside of the bearing cylinder 1-2-1, the clamping through hole can correspond to the clamping groove. The bearing cylinder 1-2-1 is also sleeved with a clamping cylinder 1-2-3, and the clamping cylinder 1-2-3 is positioned below the connecting cylinder 1-2-2. The inner wall of the clamping cylinder 1-2-3 is provided with a clamping convex block which extends transversely. The clamping convex block can penetrate through the clamping through hole and abut against the clamping groove of the pen point part 1-1 when the pen point part 1-1 is inserted into the inner wall of the bearing cylinder 1-2-1, so that the pen point part 1-1 is fixed in the bearing cylinder 1-2-1 in a clamping mode, and the pen point part 1-1 is prevented from falling off from the bearing cylinder 1-2-1.

Since the tip of the pen tip portion 1-1 continuously contacts and rubs against the touch device during the use of the user, it may be worn or even broken after a long time use. Therefore, the pen tip portion 1-1 needs to be replaced in order to meet the user's demand. In this embodiment, although the nib portion 1-1 is fixed in the barrel 1-2-1 by means of clamping, the clamping groove may be set to be an arc groove, and a chamfer matching with the clamping groove is processed at an end point of the clamping protrusion. The pen point part 1-1 can be conveniently pulled out from the bearing cylinder 1-2-1 by a user through the arc-shaped groove surface and the chamfer of the clamping convex block, and the pen point part 1-1 can not fall off from the bearing cylinder 1-2-1 without external force.

Example 3

As shown in FIGS. 9 to 12, the present embodiment proposes a pen point 1, wherein the pen point 1 comprises a pen point portion 1-1, a connecting portion 1-2 and a pressure-sensitive portion 1-3, the pen point portion 1-1 is connected to an inner frame 2 inside the pen body through the connecting portion 1-2, and the pressure-sensitive portion 1-3 is disposed on the top of the pen point portion 1-1 for detecting the pressure transmitted from the pen point portion 1-1.

Specifically, the pen point 1 provided in the embodiment is applied to an electronic pen, and is an essential part of the electronic pen. The electronic pen generally comprises two parts, namely a pen head 1 and a pen body, wherein one part of the pen head 1 can be exposed to the outside of the pen body so that a user can write on the touch device through the exposed part. The other part of the pen point 1 is positioned in the pen body and can be fixed with the inner wall of the pen body or the pen body in a mode of arranging the inner frame 2 in the pen body.

In addition, the embodiment is also provided with an elastic component 1-4 between the connecting cylinder 1-2-2 and the clamping cylinder 1-2-3. The elastic member 1-4 is compressed when the nib 1-1 moves toward the pressure-sensitive portion 1-3 by an external force and pushes the nib 1-1 back to an initial position when the nib 1-1 is not applied by the external force. The elastic members 1 to 4 may be springs, silicon rubber, or other elastic materials. Therefore, when the electronic pen moves in a space range and the pen point part 1-1 is not acted by external force, the pen point part 1-1 cannot shake in the length direction of the electronic pen, and the use condition of a user is influenced.

Example 4

As shown in fig. 13, the present embodiment provides an electronic pen, which includes a pen body 3, an inner frame, and a pen head 1. The inner frame is arranged inside the pen body 3 and used for bearing a circuit board. The pen point 1 is arranged at the front end of the pen body 3, and a part of the pen point 1 is exposed outside the pen body 3. The other part of the pen point 1 positioned in the pen body 3 is fixedly connected with the inner frame.
