The elastic sheet 2 is connected to the shell 3 through the hook 211 and then fixed on the shell 3 through the limiting piece 4, the limiting piece 4 can butt-fix or clamp-fix the hook 211, the preferred movable groove 32 can extend to the connecting end 21, so that the elastic sheet 2 can be embedded in the movable groove 32, the outer side surface of the elastic sheet 2 is flush with the outer surface of the shell 3, the elastic sheet 2 can be protected, the appearance is simpler, compared with the prior art which adopts the matching between a pin shaft with threads and a threaded hole, the hinging of the glasses leg 5 and the glasses frame is realized by adopting the matching of the hinged end 11 and the hinged shaft 321, the free end 22 is butted on the hinged end 11, so that the elasticity exists between the rotation of the glasses leg 5 and the glasses frame, the glasses frame cannot deform due to the outward rotation of the glasses leg 5 to a certain degree, the vision is influenced, the deformation of the elastic sheet 2 is caused by the hinged piece 1 in the rotation process of the glasses leg 5, thereby having enough elasticity, and the glasses leg 5 can be folded completely and opened more easily, when the glasses legs are opened beyond the range, the glasses legs 5 can automatically return to the holding heads, when a user lowers the head or does strenuous exercise, the glasses are not easy to slide down or separate, and the service life of the glasses is prolonged, the technical scheme has a simple structure, does not have more parts, can be automatically installed and used, is simpler to install, simultaneously, the hinged end 11 is provided with the chute 111, the bottom of the opening side inclines towards the direction close to the shell 3, when the hinged end 11 rotates around the hinged shaft 321, only the shell 3 rotates to the opening direction of the chute 111, the shell and the chute can be separated, but when the glasses are used daily, the glasses legs 5 are blocked by the lenses, when the glasses are in a completely folded state, the glasses legs are not easy to separate from the hinged end 11, when the glasses legs 5 need to be disassembled, only the glasses legs 5 are folded, then the shell 3 is pressed along the inclination direction of the chute 111 to enable the hinged shaft 321 to be separated from the chute 111, and the shell 3 plays a role in supporting the elastic sheet 2 and connecting the hinged parts 1 and the glasses legs 5, the structure is more stable, and meanwhile, the appearance design can be carried out on the shell, so that the structure is more attractive.

The limiting part 4 comprises a clamping plate 41 which is inserted into the casing 3 and can move along the length direction of the glasses legs 5 in a guiding manner, one end of the clamping plate 41 is arranged in the casing 3 to form a clamping end 411, a through hole 4111 for the clamping hook 211 to pass through is formed in the clamping end 411, the through hole 4111 can be aligned with the connecting hole 31 or arranged in a staggered manner through movement, after the hook part of the clamping hook 211 passes through the clamping plate 41, the clamping plate 41 can be aligned with the sunken 2111 part of the clamping hook 211 and can be embedded into the sunken 2111 part through movement to form limiting fit. One end of the clamping plate 41 is clamped and limited with the clamping hook 211, the other end of the clamping plate 41 can be used for connecting a glasses leg 5, the shape and the size of the through hole 4111 in the clamping plate 41 can be consistent with or slightly larger than those of the connecting hole 31, the connecting hole 31 on the same side with the movable groove 32 can be communicated into a whole, the forming and the size of the connecting hole 31 are determined by the clamping hook 211, during installation, the through hole 4111 and the connecting hole 31 are aligned, the clamping hook 211 sequentially penetrates through the connecting hole 31 and the through hole 4111 in one side of the shell 3, the clamping plate 41 is aligned with the sunken 2111 of the clamping hook 211, then the clamping plate 41 is moved in the direction far away from the shell 3, the clamping plate 41 is embedded into the sunken 2111 to realize clamping, when the elastic plate 2 is disassembled, only the through hole 4111 and the connecting hole 31 are aligned again, the elastic plate 2 is conveniently replaced, and if the elasticity of the elastic plate 2 is damaged or fails, the elastic plate can be replaced in time.

The hook 211 is formed by bending a convex portion toward the hinge 1, the convex portion being disposed on a side of the connecting end 21 facing the housing 3, and the bent portion of the convex portion is a concave portion 2111 of the hook 211. The trip 211 becomes 7 font, and its one end is connected on shell fragment 2 and perpendicular with shell fragment 2, and the other end constitutes spacing joint cooperation with cardboard 41, simple structure, and processing is convenient.

The connecting hole 31 penetrates the housing 3, and the bent portion of the hook 211 is exposed. The end part of the hook 211 parallel to the elastic sheet 2 is exposed, and the surface of the hook is flush with the surface of the shell 3, so that whether the elastic sheet 2 is installed in place or not can be conveniently observed, and the hook is convenient to detach.

The elastic sheet 2 is in a strip shape, a U shape, a ring shape or a sheet shape. The structure of shell fragment 2 can be diversified, when being the bar, can be two at least shell fragments 2, and during other shapes, trip 211 can be two, connects more stably, and elasticity is bigger.

A guide groove 4112 and a guide rib 33 for guiding and sliding are arranged between the clamping end 411 and the housing 3. The guiding groove 4112 is disposed on the clamping end 411 and can be U-shaped, and the two connecting holes 31 are disposed on two corresponding sides of the guiding rib 33 for guiding movement.

The end of the card 41 exposed outside the housing 3 is provided with a fixing hole 412. When being connected with mirror leg 5, can realize fixed connection through screw 6 and fixed orifices 412, and cardboard 41 is connected the back with mirror leg 5, has also restricted cardboard 41's position, avoids cardboard 41 to remove for casing 3, and simple structure realizes the locking of shell fragment 2.

The outer side of the articulated piece 1 is provided with a limiting block 12 for the shell 3 to abut against when turning outwards, and a gap X exists between the limiting block 12 and the shell 3 in the axial direction of the articulated piece 1. The setting of stopper 12 can avoid mirror leg 5 transition to turn up, leads to the elasticity of shell fragment 2 to be destroyed, and stopper 12 and casing 3 can not the butt when normally opening, just can't make mirror leg 5 turn up if the butt, so need the existence of space X, the size decision degree of turning up of space X.
