Control the touch screen. The conventional stylus is generally disposed in the portable electronic device. When the stylus is needed, the stylus is simply pulled out from the housing, so that the touch screen can be conveniently controlled. However, since the length of the housing of the portable electronic device is generally short, the stylus must be designed to be shorter when the stylus is to be inserted into the housing, thus limiting the length of the stylus. This brings a lot of inconvenience to the operator. In order to avoid the above problems, some retractable stylus pens have appeared on the market. However, the conventional retractable stylus pen has a complicated structure and is not easy to manufacture. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a retractable stylus that is relatively simple in structure and easy to manufacture. [0004] A stylus pen includes a hollow pen holder and a refill extending from the pen holder, the stylus further includes a fixing member and a sliding bar, the fixing member is fixed in the pen holder, the sliding The rod is fixed in the refill, and the sliding rod is sleeved on the fixing member. The sliding rod defines a sliding slot. The two ends of the sliding slot respectively extend with a locking hole, and the fixing member is provided with a sliding pin. The sliding pin is slidably disposed in the sliding slot to extend the refill relative to the pen holder. The lock 099110470 Form No. A0101 Page 4 / Total 20 pages 0992018450-0 201135532 The hole is for receiving the sliding pin The fixing member is locked relative to the sliding bar. Compared with the prior art, the stylus of the present invention has a simple structure and is convenient for manufacturing. The slider is slidably disposed on the fixing member, and the pen core is fixed on the slider, and the pen holder is fixed on the fixing member, so that the refill can be elongated relative to the pen holder. [Embodiment] The stylus of the present invention is suitable for portable electronic devices such as mobile phones, personal digital assistants (PDAs), and palmtop computers. Referring to FIG. 1, the stylus 100 includes a barrel 10, a fixing member 20, a slider 30, a core 40, a cap 50, a sliding pin 60, and a positioning pin 70. The fixing member 20 is fixed to the pen holder 10 by the positioning pin 70. The sliding pin 60 is fixed to the fixing member 20, and the sliding bar 30 is slidably sleeved by the sliding pin 60. On the piece 20, the refill 40 is fixed to the slide bar 30, and the cap 50 is capped to the head of the refill 40. [0008] The middle portion of the pen holder 10 is axially opened with a receiving hole 12 penetrating therethrough. The receiving hole 12 is surrounded by four side walls 122, and the side walls 122 are disposed opposite each other. A positioning hole 1 222 is defined in each of the two opposite sidewalls 122, and the positioning holes 1222 are coaxially disposed. [0009] The fixing member 20 includes a fixing rod 22 and a cover plate 24 connected to the fixing rod 22. A fixing hole 222 and a through hole 224 are respectively defined at two ends of the fixing rod 22, and the through hole 224 is disposed adjacent to the cover plate 24. The fixing hole 222 is for mounting the slide pin 60. The through hole 224 is for passing the positioning pin 70 to fix the barrel 10 to the fixing member 20. 0992018450-0 099110470 Form No. A0101 Page 5 of 20 201135532 [0010] Please refer to FIG. 2 together, the slide bar 30 includes two opposite side walls 32 and two opposite rod walls 34, the rod side wall 32 and The stem wall 34 collectively encloses a channel 36. Among them, the slide bar 30 is made of an abrasion resistant elastic material such as polyoxymethylene (POM). [0011] Each of the rod side walls 32 is provided with a sliding groove 322' penetrating therethrough, and a locking block 323 is respectively protruded from each of the rod side walls 32. The sliding groove 322 cooperates with the sliding pin 60 to guide the sliding bar 30 to slide relative to the fixing member 20. The locking block 323 is used to fix the sliding bar 3〇 to the refill 40.
