A built-in concave circular hole is provided on the fixing seat 3 at the position of the threaded hole corresponding to the threaded hole, and the outer fixed sleeve 7 is installed with the fixing seat 3 by screws. A buckle is provided on the fixing seat 3, and corresponding slots are provided on the outer fixed sleeve 7 and the inner follower sleeve 9 respectively. The buckle and the slot are embedded in cooperation, and a connecting square shaft 10 is provided in the inner follower sleeve 9. The connecting square shaft 10 passes through the fixing seat 3 and is arranged in the door and window sash 1. The connecting square shaft 10 and the fixing seat 3 are connected by a connecting sleeve 11, and the fixing seat 3 is fixedly installed in the door and window sash 1.

[0021] Furthermore, the inner follower sleeve 9 is provided with an inner square hole, which is plugged into the connecting square shaft 10 to limit the axial rotation of the two, but the inner follower sleeve 9 and the connecting square shaft 10 can move axially.

[0022] Furthermore, an inner polygonal hole is provided on the door and window handle 2, one end of the inner follower sleeve 9 is provided as a polygonal shaft body portion, the polygonal shaft body portion is inserted into the inner polygonal hole, the polygonal shaft hole cooperates and is connected with the mounting screws to fix the inner follower sleeve 9 and the door and window handle 2.

[0023] Furthermore, an outer boss portion is provided at the other end of the inner follower sleeve 9, and a cylindrical shaft portion is provided between the outer boss portion and the polygonal shaft portion. The safety spring 8 is sleeved on the cylindrical shaft portion, and one end of the safety spring 8 is against the outer boss portion. The safety spring 8 is arranged in the outer fixed sleeve 7, and an inner boss is provided in the outer fixed sleeve 7. The other end of the safety spring 8 is against the inner boss, and the inner boss is also arranged to be in contact with the door and window handle 2, so as to limit the relative axial movement of the inner follower sleeve 9 and the outer fixed sleeve 7.

[0024] Furthermore, the buckle includes a first buckle 4, a second buckle 5 and a third buckle 6, and the slot includes a first buckle 4, a second buckle 5 and a third buckle 6. The fixing seat 3 is provided with a first buckle 4 and a second buckle 5. Corresponding to the first buckle 4, a first buckle 4 is provided on the outer fixed sleeve 7, and the first buckle 4 is embedded in the first buckle slot. Corresponding to the second buckle 5, a second buckle 5 is provided on the inner follower sleeve 9, and the second buckle 5 is embedded in the second buckle slot. The fixing seat 3 is also provided with a third buckle 6. Corresponding to the third buckle 6, a third buckle 6 is provided on the inner follower sleeve 9, and the third buckle 6 is embedded in the third buckle slot. The embedding of the first buckle 4 and the first buckle, and the connection of the matching screws (the screw knob is installed in the threaded hole and inserted into the built-in concave circular hole) fix the outer fixed sleeve 7 on the fixing seat 3.

[0025] Furthermore, when the door and window handle 2 is in a state of not being pulled open, the safety spring 8 acts on the inner follower sleeve 9, and the second clip 5 is embedded in the second slot, and the third clip 6 is embedded in the third slot, so that the inner follower sleeve 9 and the fixing seat 3 are in a relatively fixed state, and the door and window handle 2 cannot rotate.

[0026] Furthermore, when the door and window handle 2 is in the opened state, the door and window handle 2 pulls the inner follower sleeve 9 to move outward, the safety spring 8 is squeezed and compressed by the outer shoulder, the second slot is free from the restriction of the second buckle 5, and the third slot is free from the restriction of the third buckle 6, so that the inner follower sleeve 9 is not subject to the circumferential restriction of the buckle on the fixed seat 3, and the door and window handle 2 can be rotated.

[0027] Furthermore, the inner side of the connecting sleeve 11 is a quadrilateral semi-arc angular cylinder adapted to the side of the connecting square shaft 10 , and the outer side of the connecting sleeve 11 is a cylindrical surface. The connecting square shaft 10 can rotate inside the fixing seat 3 when the door and window handle 2 is rotated.

[0028] During use of the utility model, since the fixing seat 3 is fixedly arranged on the door and window sash and cannot rotate, when the user does not pull the door and window handle 2 or the child has little force and cannot pull the door and window handle 2, under the action of the safety spring 8, the second buckle 5 on the fixing seat and the second groove on the inner follower shaft sleeve 9 are embedded, and the third buckle 6 on the fixing seat and the third groove on the inner follower shaft sleeve 9 are embedded, so that the inner follower shaft sleeve 9 and the fixing seat 3 are in a relatively fixed state, the door and window handle 2 cannot rotate, and the door and window sash 1 cannot be opened.

[0029] When the user is an adult or a big child with safety awareness, he pulls the door and window handle 2 outward with force, and the door and window handle 2 drives the inner follower sleeve 9 to move outward. The safety spring 8 is squeezed and compressed by the outer boss on the inner follower sleeve 9, and the inner follower sleeve 9 moves outward along the center axis connecting the square shaft 10 and the outer fixed sleeve 7 with the door and window handle 2. The second slot is free from the restriction of the second buckle 5, and the third slot is free from the restriction of the third buckle 6, so that the inner follower sleeve 9 is not subject to the circumferential restriction of the buckle on the fixed seat 3. At this time, rotating the door and window handle 2 can drive the inner follower sleeve 9 to rotate, and the inner follower sleeve 9 drives the connecting square shaft 10 to rotate, so that the door and window sash 1 can be opened.
