Touch control pen

Abstract

The invention relates to a touch control pen which comprises a main body and an air bag covering the main body. A closed space is formed between the air bag and the main body, a communicating part is arranged in the closed space, outside air can enter the closed space through the communicating part so as to expand and deform the air bag, and the air in the closed space can be exhausted through the communicating part so as to recover the deformation of the air bag. The touch control pen is provided with the air bag for covering the main body, the outside air can be charged into the air bag to expand and deform the air bag, and thus, the touch control pen becomes bigger, which is convenient for a user to hold to perform the operations of touch control, writing and the like. The air in the closed space can also be exhausted from the air bag so as to recover the air bag into the original state, so that the diameter of the touch control pen can be recovered to the original size; thus, the touch control pen can be conveniently accommodated in an electronic device, and the space occupied by the touch control pen is small.

Description

technical field [0001] The invention relates to a touch pen, in particular to a touch pen with adjustable thickness. Background technique [0002] With the popularization of handheld electronic devices and touchable liquid crystal display screens, handheld electronic devices without keyboards have gradually become the mainstream of handheld electronic consumer products. However, with the elimination of keyboards and the miniaturization of LCD screens, in order to display data on the LCD screen as much as possible, it is necessary to develop handwriting input recognition. Using stylus input has become an effective method to solve this problem. [0003] A conventional stylus includes a cylindrical main body and a nib fixed at one end of the main body. When in use, you can hold the main body and use the pen tip to touch or write on the screen. When not in use, the stylus can be stored in the socket provided on the palm electronic device, so that it is convenient to carry arou...

Problems solved by technology

However, in order to realize thinner and lighter electronic devices, it is necessary to reduce the space occupied by the stylus socket. Therefore, the main body of the existing stylus is generally thinner, and the thickness of the stylus cannot be adjusted.

It is inconvenient for the user to apply force when using the above-mentioned stylus to write, and it is easy to cause incoherent strokes and a low recognition rate when writing. In addition, long-term writing is easy to cause hand fatigue, which brings a lot of inconvenience to the user.
