One end of the clamping rod 91 is slidably inserted into the inner wall of the clamping groove 93.

[0028] Specifically, through the adjusting and telescopic mechanism 9, the user can accurately control the telescopic movement of the clamping rod 91, so as to realize the accurate adjustment of the opening and closing position of the door and window, and meet the individual needs of different users for the opening and closing degree of the door and window; the sliding and inserting design of the U-shaped seat 97 and the adjusting and driving groove 96 enables the user to adjust the position of the clamping rod 91 through simple operation without the need for complex tools or professional knowledge.

[0029] In order to realize the telescopic movement of the clamping rod 91, the other end of the U-shaped seat 97 is provided with an adjusting shaft 98 which is sleeved and installed on the inner side wall of the U-shaped seat 97. The inner side wall of the U-shaped seat 97 is also slidably inserted with an adjusting block 99, and the surface of the adjusting block 99 is provided with an inclined driving groove 910. The adjusting shaft 98 is located in the inclined driving groove 910.

[0030] Specifically, by inserting and moving the adjusting block 99 in the vertical direction, the adjusting shaft 98 is driven by the inclined driving groove 910 to slide on the inner wall of the inclined driving groove 910, thereby driving the U-shaped seat 97 to move, so as to realize the telescopic movement of the clamping rod 91 and achieve the purpose of adjusting the opening and closing degree of the door and window.

[0034] Specifically, the design of the adjusting hole 915 enables the user to directly operate the adjusting screw 914 from the outside of the buffer, without the need to disassemble the buffer or other components, thereby simplifying the adjustment process; since the cross-shaped head of the adjusting screw 914 is located in the inside of the adjusting hole 915, the user can use a screwdriver to directly rotate the adjusting screw 914, thereby directly controlling the vertical movement of the adjusting block 99; the fixed communication between the adjusting hole 915 and the adjusting driving groove 96 ensures the stability of the adjusting screw 914 during the adjustment process, thereby reducing errors caused by looseness.

[0035] By arranging the adjusting telescopic mechanism 9, the clamping rod 91 can move linearly along the surface of the connecting plate 2, accurate position adjustment is achieved, and the user can adjust according to the specific size and closing requirement of the door and window; by accurately adjusting the position of the clamping rod 91, it can be ensured that the door and window can be firmly locked after being closed, thereby preventing potential safety hazards caused by incomplete closing; the clamping block 92 can gradually slow down the moving speed of the door and window during rotation, thereby reducing the vibration during closing, further improving the buffering effect, and protecting the door and window structure from being damaged.

[0036] Working principle: in the operation of controlling the sliding glass window to move in the vertical direction, the clamping rod 91 is driven to move in the vertical direction, when moving to the top position, the end surface of the clamping rod 91 pushes the clamping block 92, so that the clamping block 92 swings along the hinged groove 94, the clamping rod 91 continues to move upwards, and the surface of the clamping rod 91 is clamped and locked with the surface of the clamping block 92; when moving downwards, the one end of the clamping rod 91 moves out of the clamping groove 93, and moves to the inner wall of the clamping groove 93 at the bottom.

[0037] When the clamping rod 91 cooperates with the clamping groove 93 of the clamping block 92, by rotating the adjusting screw 914, the limiting adjusting plate 912 is controlled to slide, thereby driving the adjusting block 99 to move in the vertical direction, the U-shaped seat 97 is controlled to move through the inclined driving groove 910 on the surface, thereby driving the clamping rod 91 to move and stretch.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
