[0026] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0027] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] The utility model will now be further described in conjunction with the accompanying drawings.

[0031] Combined with Figure 1-5 , a limit member 3 is hinged inside the pulley, and both ends of the limit member 3 are arc surfaces;

[0032] The positioning member 1 is installed under the window frame track, the positioning member 1 corresponds to the position of the pulley, a swinging member 4 is hinged on the positioning member 1, the swinging angle of the swinging member 4 is 0-45°, a concave and convex positioning point is provided on the swinging member 4, a torsion spring 5 is provided on one side of the swinging member 4 on the positioning member 1, the swinging member 4 is self-reset under the elastic force of the torsion spring 5, one end of the swinging member 4 passes through the positioning member and is slidably connected to the positioning member 1, and the positioning member 1 is located on one side of the limit member 3;

[0033] The pull rod 2 is located on one side of the positioning member 1, and a spring tongue 6 is hingedly connected on the side of the pull rod 2 facing the positioning member 1, and a hinged block is provided on the side of the spring tongue 6. Articulated rods are provided on both sides of the spring tongue 6 on the pull rod 2, and the side of the hinged block facing the hinged rod is an arc surface. The spring tongue 6 is connected to the pull rod 2 through a spring 7, and the end of the spring tongue 6 away from the pull rod 2 is a convex point;

[0034] The pulley is hinged to one end of the swing arm, the swing angle of the swing arm is 0-90 degrees, the other end of the swing arm is hinged to the swing arm seat, and the swing arm seat is connected to the window sash.

[0035] The pulleys of the two sets of positioning mechanisms are connected via a connecting rod 8 .

[0036] When in use, the positioning member 1 is provided with a torsion spring 5 and a swing member 4, and the swing member 4 can swing 0-45 degrees. The swing member 4 is provided with concave and convex positioning points, and the pull rod 2 is provided with a spring tongue 6, and the spring tongue 6 has a spring 7, and the spring tongue 6 is hinged on the pull rod 2, and the spring tongue 6 can move forward and backward.

[0037] The rotating handle drives the pull rod 2 to move left and right. The left and right movement of the spring tongue 6 and the collision with the concave and convex of the swing member 4 can move the swing member 4 to limit the passage of the pulley. The swing member 4 resets itself under the elastic force of the torsion spring 5.

[0038] When the swing arm is in the open state, two pulleys are installed in the window frame track.

The tilting lock point on the window frame and the lock pin can limit the opening of the lower side of the window sash. The contact between the convex point of the spring tongue 6 and the convex point of the swinging member can move the swinging member.

[0040] The compression spring 7 allows the limiter 3 to pass, and after passing, the swinging member 4 rebounds and resets under the pressure of the torsion spring 5. The handle is rotated, the locking point is separated from the lock nail, and the window sash moves so that the sliding limiter 3 and the swinging member 4 rub against each other at an angle, and the swinging member 4 automatically compresses the spring 7 and opens under the collision.
