The first bulges 21 are at least two, and at least one first bulge 21 is integrally formed or connected to two side edges of the lens 20, and all the first bulges 21 are arranged on the same side surface of the lens 20. The two sides of the lens frame 30 corresponding to the first protrusions 21 are respectively and pivotally connected with a connecting rod 42 through a first pivot shaft 41. Each link 42 is separately pivotably connected with a catch 44 through a second pivot shaft 43, and the first pivot shaft 41 and the second pivot shaft 43 are not coaxially arranged, and the first pivot shaft 41, the second pivot shaft 43 and the catch 44 are arranged such that when the catch 44 rotates around the second pivot shaft 43 to a position where it is closest to the first pivot shaft 41, the catch 44 can be in snap connection with the first protrusion 21, and at this time, the lens 20 is snapped between the catch 44 and the frame 30 (see fig. 1 to 3). Preferably, the first pivot shaft 41 is arranged in parallel with the second pivot shaft 43. Therefore, when the buckle 44 is in snap connection with the first protrusion 21, the structure of the quick mounting structure is more compact. In a preferred embodiment, an anti-slip structure 444 is provided on the outer surface of the buckle 44 to facilitate the user to snap-fit the buckle 44 with the first protrusion 21 by pressing the outer surface of the buckle 44, and the anti-slip structure 444 can be realized by integrally molding or machining a plurality of protrusions or recesses on the surface of the buckle 44.

Preferably, referring to fig. 3 and 5, at least one first protrusion 21 is disposed on two opposite sides of the lens 20, respectively, so as to ensure the stability of the engagement connection between the first protrusion 21 and the buckle 44. As a preferred embodiment, all the first protrusions 21 are provided on the side of the lens 20 facing away from the frame 30, whereby, when the catch 44 is caught on the outer surface of the first protrusion 21 (i.e. on the surface of the first protrusion 21 facing away from the frame 30), the side of the lens 20 facing the frame 30 abuts against the frame 30 and is caught between the catch 44 and the frame 30, so that the lens 20 can be stably mounted on the frame 30 by means of the snap connection of the catch 44 with the first protrusion 21.

Since the second pivot shaft 43 can not move towards the lens frame 30, the buckle 44 can be separated from the first protrusion 21 only by moving the second pivot shaft 43 away from the lens frame 30, so as to ensure the stability of the clamping connection between the buckle 44 and the first protrusion 21.

Illustratively, with continued reference to fig. 3 and 5, the catch 44 includes a first connecting portion 441 having one end pivotally connected to the link 42 via a second pivot shaft 43; a second connecting portion 442 provided on the other end of the first connecting portion 441; and an engaging portion 443 provided on the second connecting portion 442 for engaging with the first projection 21; the link 42 and the first connecting portion 441 are arranged such that the first connecting portion 441 abuts against an outer side surface of the link 42 when the engaging portion 443 is engaged with the first projection 21. Thus, the engaging portion 443 and the first protrusion 21 can be engaged with each other by pressing the first connecting portion 441 toward the side where the frame 30 is located, or by pressing the second connecting portion 442 toward the side where the first protrusion 21 is located, so that the operation method of connecting the hook 44 and the first protrusion 21 can be simplified. As an example, the first connecting portion 441, the second connecting portion 442, and the engaging portion 443 are integrally formed to form the buckle 44, wherein the engaging portion 443 can be formed by connecting a buckle on the second connecting portion 442, or by integrally forming or machining a slot on the second connecting portion 442 to fit the first protrusion 21. Generally, the first connecting portion 441 and the second connecting portion 442 form an included angle therebetween, that is, the two connecting portions do not extend in the same direction; preferably, the first connecting portion 441 and the second connecting portion 442 form an included angle of approximately 90 °, and when the buckles 44 on both sides of the frame 30 are engaged with the first protrusions 21 on both sides of the lens 20, the buckles 44 on both sides can include the lens 20 and the frame 30 therein, thereby improving the stability of the connection. Preferably, the first connecting portion 441 is configured such that, when the buckle 44 is in snap connection with the first protrusion 21, the extending direction of the first connecting portion 441 is the same as the connecting direction of the first pivot shaft 41 and the second pivot shaft 43, and the connecting direction of the first connecting portion 441 and the connecting rod 42 is parallel to the connecting direction of the first pivot shaft 41 and the second pivot shaft 43, so that the connecting rod 42 is at a dead point position at the time, at this time, no matter any one position of the outer surfaces of the first connecting portion 441 and the second connecting portion 442 is pressed, the buckle 44 cannot be separated from the first protrusion 21, thereby realizing firmness of connection between the buckle 44 and the first protrusion 21; at this time, if the clip 44 needs to be separated from the first projection 21, the first connecting portion 441 needs to be pulled toward the side away from the lens frame 30 to separate the first projection 21 from the engaging portion 443, and the operation of detachment is simple and easy. Preferably, the first pivot shaft 41, the second pivot shaft 43, the link 42, the first connecting portion 441 and the engaging portion 443 are arranged such that, when the engaging portion 443 is engaged with the first protrusion 21, the second pivot shaft 43 is located on a side of the first pivot shaft 41 facing away from the engaging portion 443. Thus, the first projection 21 and the engaging portion 443 can be easily separated by pulling the first connecting portion 441 away from the lens frame 30.

The connecting rod 42 rotates the buckles 44 arranged at the two sides of the lens frame 30 through the relative connecting rod 42, and simultaneously drives the connecting rod 42 connected to the buckles 44 to rotate around the first pivot shaft 41 connected with the connecting rod, so as to realize the clamping connection and the disassembly of the buckles 44 and the first bulges 21 on the lens 20: for example, the buckles 44 on both sides are rotated around the second pivot shaft 43 to the position closest to the first pivot shaft 41, so that the buckles 44 are connected with the first protrusions 21 in a snap-fit manner, and the lens 20 is fixed on the frame 30 through the buckles 44; for another example, when the latch 44 is rotated about the second pivot shaft 43 in a direction away from the first pivot shaft 41, the latch 44 can be separated from the first protrusion 21, so that the lens 20 can be separated from the frame 30.
