[0021] The door and window actuator is arranged on the window body or the door body. A square handle is inserted into the square hole 21 of the operating member 2. The operating member 2 can be driven to rotate by rotating the handle.
[0022] When the operating member 2 rotates 90° clockwise, the operating member 2 drives the driving member 3 to move to the right, and at the same time drives the first locking handle 4 to move to the right. At this time, the intermediate gear 5 is driven to move counterclockwise, and the intermediate gear 5 drives the second locking handle 6 to move to the left. The first locking member 41 and the third locking member 61 that cooperate with each other move toward each other, and the second locking member 42 and the fourth locking member 62 move toward each other; when the first circular lock catch 411 of the first locking member 41 and the second circular lock catch 421 of the second locking member 42 are locked with the first locking groove 81 of the fixed head 8, and the third circular lock catch 611 of the third locking member 61 and the fourth circular lock catch 621 of the fourth locking member 62 are locked with the second locking groove 82 of the fixed head 8, the door and window actuator is in a locked state, and the window or door body is in a closed state.
[0023] When it is necessary to open the window or door, turn the square handle to rotate the operating member 2 90° counterclockwise. The operating member 2 drives the driving member 3 to move to the left, and at the same time drives the first lock handle 4 to move to the left. At this time, the intermediate gear 5 is driven to move clockwise, and the intermediate gear 5 drives the second lock handle 6 to move to the right. The first locking member 41 and the third locking member 61 that cooperate with each other move in opposite directions in the first strip hole 72, and the second locking member 42 and the fourth locking member 62 move in opposite directions in the second strip hole 73. When the first circular lock catch 411 of the first locking member 41 and the second circular lock catch 421 of the second locking member 42 are separated from the first locking groove 81 of the fixing head 8, and the third circular lock catch 611 of the third locking member 61 and the fourth circular lock catch 621 of the fourth locking member 62 are separated from the second locking groove 82 of the fixing head 8, the door and window actuator is in the open state, so that the window or door can be opened.
[0024] In the door and window actuator of the present invention, through holes are directly opened on the first lock handle 4 and the second lock handle 6 as the first passive tooth 43 and the second passive tooth 63, thereby eliminating the passive rack that needs to be assembled additionally on the traditional door and window actuator. The structure is simple, the product is easy to assemble and can reduce costs, and the transmission efficiency and stability are higher. The door and window actuator uses mechanical locking and is sturdy and durable.
