The present invention relates to a one-touch opening and closing stylus pen which is convenient to use and prevents the main body from being pushed into the cylinder even when the user only touches the lid and improves the feeling of use.

In general, personal digital assistants are equipped with various functions for processing Internet functions, text information, graphics, etc. in addition to basic functions for transmitting and receiving voices with other parties. According to the trend of light weight and miniaturization, the touch screen method or voice input method that does not need a separate keypad is introduced and used.

Among them, a stylus pen is used to operate a touch screen terminal. The stylus pen is formed in the shape of a writing instrument, and a tip for inputting and outputting information is formed at an end portion. Such a stylus pen is generally mounted on a terminal, but is configured to have a size sufficient to be held and used in a hand, and it is a recent trend to carry it separately from the terminal.

As shown in FIG. 6, the stylus pen 100 according to the related art has a main body 110 having a tip 111 for a touch input formed at the tip of a rod 113 of a piston, and the main body 110 is inserted therein. It is roughly divided into a cylinder 130 accommodated and a lid 150 coupled to the cylinder 130. Caps 137 and 153 are coupled to the cylinder 130 and the lid 150, respectively, and hooks 159 are attached to the cap 153 of the lid. When the main body 110 enters the cylinder 150 at the maximum, a portion of the tip and the rod is exposed to the outside, and the lid 150 is coupled to the cylinder 130 by the screws 131 and 151.

With this configuration, when not in use, the stylus pen body 110 is easily carried on a necklace or the like using the hook 159 provided in the lid 150 while being accommodated in the inner space of the cylinder 130 and the lid 150. In use, the main body side bundle 100a coupled to the cylinder from the lid 150 is separated, and then the main body 110 is pulled out from the cylinder 130 for a predetermined length.

By the way, such a prior art has a problem that time is delayed and troublesome to use because the screw coupling must be released by rotating the screw coupling at the time of separating the body-side bundle 100a from the lid 150.

In addition, for example, when hanging on a necklace type, the screw is loosened due to the walking flow, and the body-side bundle is inadvertently fled away, and only a lid is left.
