Embodiment Construction

[0046] Figure 1A and Figure 1B It is a schematic diagram of the states of the retractable pen and the portable electronic device according to an embodiment of the present invention, which is used to show the retractable state of the retractable pen and the corresponding relationship with the portable electronic device. Figure 1C and Figure 1D It is a schematic diagram of the telescopic state of the telescopic pen. In this embodiment, the retractable pen 100 is, for example, a stylus, which is used to be accommodated in a portable electronic device 20 (such as a tablet computer, but not limited thereto), so as to facilitate the user to move it from the portable It can be taken out from the portable electronic device 20 for controlling the portable electronic device 20. Once it is no longer used, it can be stored in the portable electronic device 20 to facilitate carrying. Here, the retractable pen 100 includes a pen case 110, a pen shaft 120 and a pen cap 130, such as Fi...

Abstract

The invention provides a telescopic pen which is used for being contained in a portable electronic device. The telescopic pen comprises a pen shell, a pen shaft, a pen cover, a driving part and an elastic part. The pen shaft is fixed in the pen shell and is provided with a first ratchet structure. The pen cover is provided with a second ratchet structure which can be movably engaged with the firstratchet structure. The driving part is rotationally arranged on the pen shaft in a sleeving manner and is located in the pen cover. The driving part is provided with a third ratchet structure, and the elastic part is arranged on the pen shaft in a sleeving manner and abuts against the part between the pen shaft and the driving part. The elastic part constantly drives the driving part to move towards the first ratchet structure or the second ratchet structure. In the first state, the third ratchet structure abuts against the first ratchet structure; and in the second state, the third ratchet structure is movably engaged with the second ratchet structure and abuts against the first ratchet structure to push the pen cover away from the pen shell.

Description

technical field [0001] The invention relates to a retractable pen, in particular to a retractable pen suitable for being accommodated in a portable electronic device. Background technique [0002] Many current portable electronic devices, such as tablet computers, smart phones and notebook computers, all use touch display screens, allowing users to directly input commands on the display screen to control electronic products. Most of the current touch display screens use the user's finger or stylus to perform the touch function. [0003] However, in order to facilitate the operation of the user, most portable electronic devices are equipped with a groove for accommodating the stylus. The casing forms a broken surface or a depression so that the user can conveniently apply force to take out the stylus from the portable electronic device. However, these broken surfaces or dents cause the portable electronic device to have an unfavorable appearance. Contents of the invention...
