[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] Figure 1-Figure 4 This is a specific embodiment of the utility model, which is a positioning type tightening and fixing device universal for multiple profiles. A hexagon socket screw 1 is connected to the frame fixing plate 2, and a rotating piece 4 is fastened to the bottom of the hexagon socket screw 1. The frame fixing plate 2 is fixed to the window frame profile 6 by making the rotating piece 4 stuck in the notch of the window frame profile 6. A groove is formed on the frame fixing plate 2, and two through holes are formed in the groove, one of which is plugged with the hexagon socket screw 1, and the other through hole is plugged with a gear device 5. A rotating piece 4 is threadedly connected to the bottom of the frame fixing plate 2 through the hexagon socket screw 1, and a sealing ring 3 is provided between the rotating piece 4 and the frame fixing plate 2, which is sleeved on the hexagon socket screw 1. A protrusion is provided at one end of the rotating piece 4, and the protrusion is in contact with the gear device 5, and the gear device 5 is used to limit the rotating piece 4.

[0021] The specific usage of this embodiment is as follows:

[0022] In the initial state, the hexagon socket screw 1 and the rotating piece 4 are in a thread-loose state, and the stop device 5 blocks the rotating piece 4 from rotating counterclockwise, which is the initial positioning state and can only rotate clockwise. When the hardware is set on the window frame profile 6, the hexagon socket screw 1 is rotated clockwise with a hexagon socket wrench to drive the rotating piece 4 to rotate. After the rotating piece 4 rotates 90 degrees, the profile notch clamps the rotating piece 4 to fix it, and then the hexagon socket screw 1 is rotated with a hexagon socket wrench until the hexagon socket screw 1 and the rotating piece 4 are in a tightened state, and the hexagon socket wrench is no longer rotated to fix the hardware.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
