Description of the Invention: [Technical Fields of the Invention] [0001] The present invention relates to a fixing mechanism, and more particularly to a fixing mechanism for fixing a peripheral member to an electronic device. [Prior Art] [0002] Electronic devices such as notebooks and mobile phones are usually provided with a fixing mechanism for detachably fixing the peripheral components of the electronic device to the electronic device. [0003] A latching mechanism for securing to a peripheral component of an electronic device. The locking mechanism includes a casing, a pressing member, a slider and an elastic member. The casing has a receiving portion for receiving the peripheral component. The pressing member is movably disposed in the casing and adjacent to the receiving portion. The elastic member is sleeved on the pressing member and abuts against the casing. The slider has a first end that contacts the pressing member and a second end that contacts the peripheral component. A positioning groove is defined in a sidewall of the receiving portion. The peripheral component is provided with a positioning protrusion that cooperates with the positioning groove. When the article is pushed toward the first end of the slider, the second end of the slider pushes the peripheral component to disengage the positioning protrusion Q from the positioning slot, and the peripheral component is removed from the receiving portion. The middle is jacked up to facilitate the removal of the peripheral component. [0004] However, it is difficult for the fixing mechanism to firmly fix the peripheral component in the receiving portion of the casing. For example, when the electronic device is subjected to a violent impact, the positioning protrusion is easily separated from the positioning groove, thereby making the peripheral component It is easy to get out of the housing of the casing. SUMMARY OF THE INVENTION [0005] In view of the above circumstances, it is necessary to provide a fixing mechanism in which the peripheral components of the fixed electronic device are relatively strong. 099100458 Form No. A0101 Page 5 of 19 0992001006-0 201124634 _6] A fixing mechanism for fixing peripheral components of an electronic device, the fixing mechanism including a casing, a pressing member, a sliding member, a first elastic member and The casing is rotatably connected to the connecting rod assembly, and the casing is provided with a receiving portion for receiving the peripheral component, and the pressing member is movable on the casing and adjacent to the receiving portion, and the sliding member is slidably disposed on the casing and pressed The first elastic member abuts between the pressing member and the casing, and the peripheral member is provided with a first engaging portion and a second engaging portion.
