  4. 4 . The quick release mechanism as claimed in claim 3 , wherein: said latching portion of said fastener member has a plurality of said extensions spaced apart from each other, and a plurality of aid engaging hooks respectively connected to one ends of said extensions; when said operating portion of said fastener member is not operated, said engaging hooks are engaged with said inner side surface of said inner bearing body; and when said operating portion of said fastener member is operated, said extensions are deformed to move toward each other and allow said engaging hooks to pass through said enlarged hole section and out of said inner hole section.
  5. 5 . The quick release mechanism as claimed in claim 2 , wherein said outer bearing body of said connecting member has a curved slide groove formed in said outer side surface thereof, said fastener member further includes a positioning pin extending inwardly from said inner side surface of said operating portion and slidably received in said curved slide groove.
  6. 6 . The quick release mechanism as claimed in claim 5 , wherein said outer bearing body of said connecting member further has a curved guide groove formed in said outer side surface thereof and located between said through hole and said curved slide groove, said fastener member further including a guide pin extending inwardly from said inner side surface of said operating portion and slidably received in said curved guide groove.
  7. 7 . The quick release mechanism as claimed in claim 6 , wherein said curved slide groove of said connecting member has an intermediate groove section, and two positioning groove sections respectively located on two opposite ends of said intermediate groove section.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Taiwanese Utility Model Patent Application No. 112202063, filed on Mar. 9, 2023. FIELD The disclosure relates to a quick release mechanism, and more particularly to a quick release mechanism that allows quick replacement of eyeglass components. BACKGROUND Referring to FIG. 1, eyeglasses 1 with a replaceable lens, as disclosed in Taiwanese Patent Publication No. 202132864, includes a glass frame 11, a lens body 12 disposed under the glass frame 11, and a lens frame 13 detachably mounted to a lower end of the lens body 12. The lens body 12 has a plurality of spaced-apart protrusions 121 protruding from an outer periphery thereof. The lens frame 13 has an embedded groove 131 opening upwardly and corresponding to the lower end of the lens body 12, and a plurality of engaging grooves 132 located in the embedded groove 131 and respectively corresponding to the protrusions 121. During assembly of the eyeglasses 1, the lens body 12 is first disposed under the glass frame 11, after which the lens body 12 is aligned with and then inserted into the embedded groove 131 of the lens frame 13. Next, the protrusions 121 are engaged respectively with the engaging grooves 132, thereby assembling the lens frame 13 to the lens body 12. Although the eyeglasses 1 can be replaced with different lens bodies 12 or lens frames 13 to achieve different functions of sun protection, safety, special appearance, etc., in order to stably connect the lens frame 13 to the lens body 12, the number of the protrusions 121 must often be more than four. As such, to assemble or disassemble the lens body 12, it is necessary to apply multiple forces to complete the engagement or disengagement of the protrusions 121 with the respective engaging grooves 132, thereby resulting in complicated assembly and disassembly steps. Moreover, to remove the lens body 12 of the eyeglasses 1, it is necessary to apply a large external force so as to slightly deform the lens frame 13, and only then can the protrusions 121 be disengaged from the respective engaging grooves 132. However, the aforesaid operation may easily cause damage to the lens frame 13 or the lens body 12 during application of the external force. Furthermore, after the lens frame 13 is removed from the lens body 12, it is also necessary to remove the lens body 12 from the glass frame 11, and only then can the lens body 12 be replaced. Hence, removal and replacement of the lens body 12 of the eyeglasses 1 are also complicated. SUMMARY Therefore, an object of the present disclosure is to provide a quick release mechanism for eyeglasses that can allow quick replacement of eyeglass components. According to this disclosure, the quick release mechanism for eyeglasses includes a connecting member and a fastener member. The eyeglasses includes an eyeglass component formed with at least one engaging groove. The at least one engaging groove has an engaging section, and an opening section communicating with the engaging section and having a width measured in a top-bottom direction smaller than a diameter of the engaging section. The connecting member is configured to be removably disposed on one side of the eyeglass component, and is formed with an accommodating groove for receiving the one side of the eyeglass component. The fastener member is provided for positioning the connecting member on the one side of the eyeglass component, and includes an operating portion located outside the connecting member, and a latching portion extending inwardly from an inner side surface of the operating portion into the connecting member and the engaging section. The latching portion has a maximum length greater than the width of the opening section but less than the diameter of the engaging section. The latching portion has two long sides, and two short sides each connected between one ends of the long sides. The maximum length of the latching portion is measured between the two short sides. Each short side has a width measured in the top-bottom direction less than the width of the opening section and the diameter of the engaging section. The operating portion is operable to drive the latching portion to rotate, and is movable between a locking position, in which the connecting member is positioned on the eyeglass component, and an unlocking position, in which the connecting member is allowed to detach from the eyeglass component. When the operating portion is in the locking position, neither of the short sides of the latching portion is facing the opening section, and the latching portion is positioned in the engaging section; and when the operating portion is in the unlocking position, one of the short sides of the latching portion is facing the opening section, and the latching portion is allowed to move out of the engaging section through the opening section.
