Field of the Invention The present invention relates to a stylus, and more particularly to a stylus applied to a portable electronic device. [Prior Art] At present, more and more portable electronic devices such as mobile phones, personal digital assistants (PDAs), and palm-top computers use touch screens, so a stylus is required to operate the touch screen. The conventional stylus is generally disposed in the portable electronic device. When the stylus is required, the stylus is simply pulled out from the casing, so that the touch screen can be conveniently controlled by the pen. However, due to the limitation of the length of the portable electronic device housing and the limitation of the internal space, the stylus is also designed to be shorter, which brings inconvenience to the operator. In order to avoid the above problems, some elongated stylus pens have appeared on the market, but the structure of the refills and pen holders of most of the stylus can be complicated and difficult to manufacture. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a retractable stylus with a simple structure, a stylus pen, including a single cylinder, a refill telescopically received in the pen holder, a fixing member and a positioning One end of the refill is provided with a card slot, and the fixing member and the positioning member are respectively mounted on the two ends of the pen holder, and a protrusion and a protrusion are respectively arranged on the inner side of the fixing member and the positioning member, and the protrusion and the protrusion are selected. Resisting the card slot to position the refill relative to the pen holder 099109544 Form No. A0101 Page 3 / Total 18 Page 0992016948-0 201132510 [0005] Compared to the prior art, the present invention is respectively assembled by two ends of the pen holder. The fixing member and a positioning member are provided with a card slot on the refill for respectively engaging with the protrusion of the fixing member and the protrusion of the positioning member, thereby positioning the stylus at different positions of the pen holder. The handwriting_structure is simple and easy to manufacture. [0006] Referring to FIG. 1 and FIG. 2, a preferred embodiment of the present invention discloses a stylus 100 suitable for use in a portable electronic device such as a mobile phone. The stylus 100 includes a barrel 10, a fixing member 20, a positioning member 30, a core 40, and a cap 50. The fixing member 20 and the positioning member 30 are fixed to the two ends of the pen holder 10. The refill 40 is sleeved in the fixing member 20 and is telescopically received in the pen barrel 10. The cap 50 covers one end of the refill 40. Referring to FIG. 2 and FIG. 3, the pen holder 10 is a hollow cylinder having a receiving cavity 12 formed therein. The inner walls of the two ends of the pen holder 10 are respectively provided with a first inner thread 14 and a second inner thread 16. The fixing member 20 includes an annular portion 22, a fixing portion 24 and a locking portion 26 which are coaxially connected in this order. A through hole 27 is formed in the fixing member 20, and the through hole 27 penetrates the annular portion 22, the fixing portion 24 and the locking portion 26 to pass the refill 40 through the fixing member 20. The annular portion 22 has a radial dimension comparable to that of the pen holder 10 so as to be resisted at one end of the pen holder 10. The fixing portion 24 and the locking portion 26 can be accommodated in the accommodating cavity 12 of the pen holder 10. An outer thread 242 is formed on the fixing portion 24, and the outer thread 242 is engaged with the first female thread 14 to fix the fixing member 20 to one end of the pen holder 10. The locking portion 26 includes two opposite arcuate abutting arms 262. An arcuate protrusion 264 protrudes from an inner wall of each of the abutting arms 262, and the protrusions 264 of the two abutting arms 262 are oppositely disposed. The inner diameter of the locking portion 26 is larger than the inner diameter of the fixing portion 24, thereby forming an annular shape at the junction of the locking portion 26 and the fixing portion 24 099109544 form number A0101 page 4 / 18 pages 0992016948-0 201132510. Stop 28 (see Figure 4). The two abutting arms 262 can also be integrally connected as long as the protrusions 264 have a constant elasticity. [0011] [0011] 099109544 The positioning member 30 is identical in shape and size to the fixing member 20 in the embodiment. The positioning member 30 includes an annular portion 32, a positioning portion 34 and a locking portion 36. The outer portion of the seat portion 3 4 is provided with a threaded portion 342 which cooperates with the first female thread 16 to fix the positioning member 3''' to one end of the pen holder 1''. The inner wall of the locking portion 36 protrudes from two opposite annular projections. Since the positioning member (10) has the same structure as the fixing member 20, the remaining features will not be described again. The refill 40 includes a cylindrical barrel 42 and a tail 44 and a pair of heads 46 connected to the ends of the barrel. The length of the tail 44 is greater than the diameter of the barrel 仏 to the junction of the tail 44 and the barrel 42. A resisting portion 442 is formed. When the pen holder 42 slides in the pen holder 1 (), the abutting portion 442 can abut against the stopping portion 28 of the fixing member 20. The pen tail 44 defines a slot 444 in the longitudinal direction. 'To divide the tail 44 into two opposite holding arms 446, the outer circumference of each holding arm 446 is recessed to form a card slot (4). When the writing core is in an unused state, the card slot 448 can be aligned with the positioning member 3 The bump 362 is clamped so that the pen anger 40 is completely accommodated in the pen holder 1 (); when the refiller pulls out, the card slot 448 can be engaged with the protrusion 264 of the fixing member 2 , to make the pen The core 4 is positioned opposite to the pen holder 10. The 4 pen head 46 is in the shape of a cone for triggering the touch screen of the electronic device (not shown). The outer circumference of the wire head 46 is recessed to form a ring-shaped recess 462. The cap 5 includes a cap cylinder 52, a gripping member 54 and a retaining member 56. The cap cap 52 is a hollow cylinder with an open end The card sacrificial element 54 is substantially a ring sleeve having the form number Α0101 % 5 Κ / , 卟 page 099201694 201132510 [0012] [0014] [0014] installed in the cap cylinder 52. The card An annular convex portion 542 and a stopper 544 (refer to FIG. 4) are protruded from the inner wall of the holding member 54. The convex portion 542 cooperates with the groove 462 of the pen head 46 so that the cap 50 covers the refill 40. The second stopper The 544 is used for stopping the pen head 46. The stopper 56 can be fixed to the inner wall of one end of the open end of the cap tube 52 by heat fusion or snapping or screwing, and resists the holding member 54 to block the holding member. 54 is disengaged from the cap tube 52. In the present embodiment, the 'stop member 56 and the cap tube 52 are fixed by screwing. To facilitate carrying the stylus 100, the cap 50 can be fixed with a sling (Fig. Please refer to FIG. 4 'Assembling the stylus 1 可 can be performed as follows. First, the fixing member 20 is fixed to one end of the pen holder by screwing. The refill 40 is provided with a writing head. One end of the 46 is inserted from the other end of the pen holder 1〇, and the pen tip 46 is exposed from the fixing member 2. Next, it will be fixed The piece 30 is fixed to one end of the pen holder 1 〇 relative to the fixing member 20 by a threaded dragon. Then the reel 4σ is pushed toward the accommodating cavity of the pen holder 1 , until the 440 and the positioning slot 448 are positioned at the end 44 [0015] Then, the cap 50 is assembled, the card holder 52 is first received in the cap tube 52, and the stopper 56 is fixed to the cap tube 52. The open end is such that the stopper 56 abuts against the retaining member 54. [0016] Finally, the assembled cap 5 is attached to the tip 46 and the projection 542 and the tip 46 are attached. The groove 462 is held. Such as the assembly.
