By the rotational movement of the first link 4 with respect to the link housing 3, the protruding height of the first end of the first link 4 with respect to the inner surface of the first side wall 34 of the link housing 3 can be adjusted.

Further, in order to enhance the external appearance of the connection housing 3, it is preferable that the outer surfaces of the connection housing 3 other than the positions of the insertion port 32 and the connection hole 33 are closed surfaces.

Further, considering that the first end of the first connector 4 may abut against the engaging protrusion 51 during the assembling and disassembling operations of the temple 2 and the frame 1 by the user, if the first end of the first connector 4 also includes a screw structure, damage may be caused to the surface of the engaging protrusion 51 during the operation, and thus, in order to avoid this phenomenon, it is preferable that no screw be provided at the portion of the first connector 4 that abuts against the engaging protrusion 51.

Specifically, referring to fig. 10, along the height direction C of the first connecting member 4, the first connecting member 4 includes a first connecting section 41 and a third connecting section 43, the first connecting section 41 protrudes from the inner surface of the first side wall 34 of the connection housing 3, and no screw thread is provided on the outer peripheral surface of the first connecting section 41; the third connecting section 43 is at least partially located in the connecting hole 33, and the outer circumferential surface of the third connecting section 43 is provided with threads.

Further, it is considered that the second connection section 42 may be provided in the middle of the first connection section 41 and the third connection section 43, since the distance between the conical surface and the wall of the connection hole 33 may be large if a part of the first connection section 41 is located in the connection hole 33, affecting the fitting structural strength of the first connection member 4 and the connection housing 3. In use, the second connecting section 42 may be located wholly or partially within the connecting aperture 33, with the outer peripheral surface of the second connecting section 42 being nearer to the wall of the connecting aperture 33.

Further, in view of the usual dimensions of the spectacles and the general demands of the user for the minimum values of the insertion force and the minimum values of the extraction force, it may be preferred that the protruding height of the first end of the first connecting piece 4 with respect to the inner surface of the first side wall 34 of the connecting housing 3 is not more than 1 mm.

Wherein, when the first connecting member 4 includes the aforementioned first connecting section 41 and second connecting section 42, the protruding height of the first connecting section 41 and second connecting section 42 together with respect to the inner surface of the first side wall 34 of the connecting housing 3 is not more than 1 millimeter.

Wherein the shape and size of the mounting groove 441 is adapted to the shape and size of the tool. For example, when the tool is a screwdriver with a straight cross section, the cross section of the mounting groove 441 may be straight or cross-shaped; when the tool is a hexagonal cross-section screwdriver, the cross-sectional shape of the mounting groove 441 may be hexagonal.

Correspondingly, referring to fig. 9, in the height direction B of the connection hole 33, the connection hole 33 includes a first hole section 331 and a second hole section 332, the cross-sectional area of the second hole section 332 being larger than that of the first hole section 331; the hole wall of the first hole section 331 is provided with threads, the hole wall of the second hole section 332 is not provided with threads, and the hole wall of the second hole section 332 is matched with the outer peripheral surface of the fourth connecting section 44 in shape and size.

Optionally, in order to enable the clamping protrusion 51 to more smoothly pass over the first end of the first connecting member 4, so that a user obtains better operation experience when assembling or disassembling the temple 2 and the frame 1, it may be further preferable that a surface of the clamping protrusion 51, which will contact with the first end of the first connecting member 4, is an arc surface or a plane surface. Specifically, referring to fig. 4, in the first direction a, the snap protrusion 51 includes a first mating surface 511 and a second mating surface 512 that are sequentially disposed, and the first mating surface 511 and the second mating surface 512 are cambered surfaces or planes.

Wherein, when the first mating surface 511 and the second mating surface 512 are planar, the slope of the planar surface with respect to the first direction a is not limited; when the first mating surface 511 and the second mating surface 512 are curved surfaces, the curvature of the curved surfaces with respect to the first direction a is not limited. In addition, the first mating surface 511 and the second mating surface 512 may or may not be directly connected.

Further, in order to make the engagement protrusion 51 easily engage with the first end of the first connector 4 and make the engagement less likely to be released by being shaken after the engagement, the inclination angle or the curvature of the first mating surface 511 and the second mating surface 512 with respect to the first direction a may be set to be different. Specifically, the inclination angle or curvature of the first mating surface 511 is larger than the inclination angle or curvature of the second mating surface 512 with respect to the first direction a. So that the minimum value of the insertion force required to be applied when the temple 2 and the frame 1 are assembled by the user is smaller than the minimum value of the extraction force required to be applied when the temple 2 and the frame 1 are disassembled.

Further, for ease of machining, it may be preferable that both the first mating surface 511 and the second mating surface 512 be planar. It may be preferable that the angle between the first direction a and the first mating surface 511 is 55-65 degrees, and the angle between the first direction a and the second mating surface 512 is 25-50 degrees.

It should be noted that, since one plane may form four angles with respect to the first direction a, at most, two angles are included, and the sum equals 360 degrees, the included angle between the first direction a and the first mating surface 511 and the included angle between the first direction a and the second mating surface 512 in the present embodiment refer to angles with smaller angle values. For example, when the first mating surface 511 is perpendicular to the first direction a, the four angles are all right angles, and the inclination angle of the first mating surface 511 with respect to the first direction a is 90 degrees; when the first mating surface 511 is not perpendicular to the first direction a, the four angles formed include two angle values of 120 degrees and 60 degrees, and the inclination angle of the first mating surface 511 with respect to the first direction a is 60 degrees.

As can be seen from the above embodiments of the present utility model, the glasses disclosed in the present utility model form and release the clamping connection through the clamping protrusion 51 and the first end of the first connecting piece 4, so that not only the detachable connection between the temple 2 and the frame 1 can be achieved, but also the protruding height of the first end of the first connecting piece 4 relative to the inner surface of the first side wall 34 of the connection housing 3 can be adjusted, so that the magnitude of elastic deformation generated by the stress of the first connecting piece 4 and/or the second connecting piece 5 can be correspondingly adjusted, that is, the minimum value of the insertion force and the minimum value of the extraction force applied between the clamping protrusion 51 and the first end of the first connecting piece 4 can be adjusted when the user performs the assembly or disassembly operation of the temple 2 and the frame 1, thereby meeting the diversified demands of different users on the minimum operation force.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
