[0015] according to Figure 1-7The present embodiment discloses a pair of spring-type glasses with replaceable lenses, comprising a frame 1 and temples 20 rotatably connected to the frame 1. The frame 1 is provided with a detachable lens 2, and a placement groove 3 adapted to the upper portion of the lens 2 is provided on the frame 1. By providing the placement groove, the lens is limited, and the detachment groove on the lens corresponds to the limit bar. The frame 1 is provided with a movable groove 4 running through the front and back, and a fixing plate 5 fixedly connected to the frame 1 is provided in the movable groove 4. A movable hole 6 is provided in the middle of the fixing plate 5 and connected to the movable groove 4. An upper guide bar 7 and a lower guide bar 7 fixedly connected to the frame 1 are provided in the movable hole 6. Guide bar 8, the frame 1 is provided with a movable part, the movable part includes a movable rod 9 movably set in the movable hole 6 and the movable groove 4 and a limit plate 10 fixedly set on the movable rod 9, the movable rod 9 is provided with a guide groove 11 matching the upper guide bar 7 and the lower guide bar 8, and the movable rod is provided with a guide groove matching the guide bar of the frame to facilitate the movable rod to move on the frame. The limit plate 10 is located in front of the fixed plate 5 and is connected to the fixed plate 5. The movable rod is slidably mounted on the guide bar, driving the limit plate to move relative to the fixed plate. The fixed plate is located between the guide bar and the limit plate. The movable rod 9 has a limit strip 12 fixed in front of the movable rod 9, and the edge of the limit strip 12 protrudes from the edge of the movable rod 9. The lens 2 is provided with a slot 13 adapted to the front of the movable rod 9 and a disengagement slot 14 adapted to the limit strip 12. The disengagement slot 14 is located on one side of the slot and is connected with the slot 13. When the movable rod is moving, the movable rod will drive the limit strip to move. When the limit strip moves to correspond to the slot, the lens is fixed to the frame. When the limit strip moves to the disengagement slot, the lens can be The movable rod 9 is provided with a positioning component, which makes it convenient to fix the movable rod and avoid the random movement of the movable rod. When the lens needs to be replaced, the movable rod is pushed horizontally, and the movable rod moves toward the direction of the temple. The movable rod drives the limit bar to move, and the limit bar corresponds to the disengagement groove. Then the old lens is removed, and the upper part of the new lens is placed in the placement groove, and the disengagement groove corresponds to the limit bar. Then the movable rod is pushed in the opposite direction, and the movable rod drives the limit bar to move to fix the lens.
