Referring to FIG. 1, a first exemplary embodiment of a stylus 50 applied in a portable electronic device (not shown), includes a main body 10, a sliding member 20, a holding member 30, a supporting member 40, and two positioning members 45. The sliding member 20 is slidably sleeved on the main body 10. The holding member 30 is rotatably connected to the main body 10. Two ends of the supporting member 40 are hinged to the sliding member 20 and the holding member 30 correspondingly.
The main body 10 includes a connecting portion 11, a shaft portion 13, and a nib 15. The connecting portion 11 is between the shaft portion 13 and the nib 15. A radius of the connecting portion 11 is larger than a radius of the shaft portion 13. A stepped surface 16 is formed on the main body 10 between the connecting portion 11 and the shaft portion 13. A plurality of latching holes 18 are defined in a straight line in the shaft portion 13 parallel to the axis of the shaft portion 13. In the illustrated exemplary embodiment, the main body 10 is cylindrical.
The sliding member 20 includes a through hole (not shown) running through two opposite ends of the sliding member 20. A projection 25 is extended from an outer surface of the sliding member 20 and used to hinge the sliding member 20 to one end of the supporting member 40. In the illustrated exemplary embodiment, the sliding member 20 is a hollow cylinder.
The holding member 30 includes a first hinging portion 31 and a second hinging portion 33. The first hinging portion 31 is formed on an end of the holding member 30. The holding member 30 can rotate relative to the main body 10 by the first hinging portion 31 rotatably connecting the holding member 30 to an end of the connecting portion 11 adjacent to the stepped surface 16. The second hinging portion 33 is extended from the middle of the holding member 30 and used to hinge the holding member 30 to the other end of the supporting member 40. In the illustrated exemplary embodiment, the holding member 30 is cylindrical for comfortable grasping by a user.
When assembling the stylus 50, the holding member 30 is rotatably connected to the main body 10 by the first hinging portion 31 engaging with the connecting portion 11.
