Then, the two rectangular threaded connecting blocks 203 move the positioning assembly 3 downward under the action of the threads, and then pull out the limiting rod 403 from the inside of the limiting socket 306. Then, by clamping the handle 405 in the rectangular notch opened at the tail end of the limiting plate 406, the limiting rod 403 in the pulled-out state is achieved. Then, a front positioning lever 303 is pulled outward, and under the cooperation of the rack 305 and the synchronous gear 307, a rear positioning lever 303 is moved outward synchronously.

[0037] Then place the aluminum alloy doors and windows into the grooves opened on the limit seat 103, and then manually rotate the synchronization rod 201 in the opposite direction, thereby causing the two second bevel gears 205, the two first bevel gears 204 and the two driving screws 202 to rotate in the opposite direction, and then the two rectangular threaded connecting blocks 203 move the positioning assembly 3 upward under the action of the threads. When the positioning assembly 3 moves upward to a suitable height, stop rotating the synchronization rod 201.

[0038] When the height of the positioning assembly 3 is adjusted, the front positioning lever 303 is pushed inward (the rear positioning lever 303 can also be pushed inward), and with the cooperation of the rack 305 and the synchronous gear 307, the rear positioning lever 303 is moved inward synchronously, so that the rubber anti-slip pads 304 on the opposite sides of the two positioning levers 303 contact the front and rear sides of the aluminum alloy door and window, and then the limiting rod 403 is inserted into the limiting hole 306 to realize the limiting effect on the sliding column 302, so that the two positioning levers 303 in the positioning state can obtain an effective limiting effect.
