[0032] Principle and process of this utility model:

[0033] The main frame 3 is installed in the window hole by using expansion bolts. Then, the user inserts the lower ends of several T-shaped locking plates 41 on the surface of the outer frame 2 between the two reinforcing plates 5 and into the slots 7, and makes the two sides of the upper ends of the T-shaped locking plates 41 located just above the reinforcing plates 5;

[0034] When one end of the tempered glass 1 is installed in the outer frame 2, the user then inserts a cross screwdriver into the cross slot of the connecting rod 45, and rotates the connecting rod 45 to drive the bevel gear 1 44 to rotate, which drives the bevel gear 2 46 to rotate. The bevel gear 1 44 drives the screw 42 to rotate, and then drives the T-shaped locking plate 41 to move in the rectangular groove 43 so that the two sides of the T-shaped locking plate 41 are in close contact with the surface of the reinforcing plate 5 and apply pressure. Because the diameter of the bevel gear 2 46 is larger than the rectangular groove 43, the outer frame 2 and the tempered glass 1 can be pulled to move, so that the outer frame 2 moves toward the edge of the main frame 3, thereby achieving the effect of limiting and fixing. With the locking of the T-shaped locking plate 41 around the outer frame 2, the tempered glass 1 is quickly installed. At this time, the limiting plate 6 is in close contact with one end of the T-shaped locking plate 41, and the other end of the T-shaped locking plate 41 is in close contact with the inner wall of the main frame 3 to fix the outer frame 2.

[0035] Afterwards, the user can install the two fixing buckle plates 10 .

[0036] In summary, the device can install the tempered glass 1 on the main frame 3 by rotating the connecting rod 45 with a cross screwdriver. The installation and disassembly of the tempered glass 1 can be achieved by rotating the connecting rod 45 in different directions, which is very fast and convenient.
