Specifically, the window opener comprises a base 1, one side of the base 1 is provided with a crank 2, and the other side is provided with a gear arm 3. The crank 2 and the gear arm 3 are drivingly connected through a transmission mechanism 4. The transmission mechanism 4 can be designed in various ways. In this embodiment, the worm 41 and the arc-shaped rack 42 are drivingly connected, the rotary motion is converted into the plane rotation of the gear arm 3, so that the gear arm 3 can be extended and retracted. The crank 2 is manually or electrically driven to rotate, the transmission mechanism 4 controls the extension and retraction of the gear arm 3, so as to adjust the window to the appropriate angle. In this embodiment, it can be defined that the driving crank 2 is forward rotated, the gear arm 3 is extended, and the driving crank 2 is reversely rotated, the gear arm 3 is retracted.

One end of the pin 7 is provided in the mounting hole 31 of the gear arm 3, and the gear arm 3 rotates around the pin 7. When the arc-shaped rack 42 is driven to rotate, the gear arm 3 rotates around the pin 7, so that the gear arm 3 extends outward or retracts inward, thereby adjusting the window angle to increase or decrease.
[0036] As shown in the figure, Figure 2 One end of the gear arm 3 away from the transmission mechanism 4 is provided with a pulley 32. The pulley 32 can slide in the sliding groove 93 in the window body 92, thereby reducing the friction, so that the angle adjustment is more convenient and smooth.
[0037] As Figure 3 and Figure 4 shown, the transmission mechanism 4 includes a worm 41 installed on the base 1 and an arc-shaped rack 42 provided on the gear arm 3, the worm 41 is provided with helical teeth 411 and is engaged with the arc-shaped rack 42, the worm 41 is installed inside the worm mounting hole 11 on the base 1, the worm 41 is connected with the handle 2; the handle 2 rotates to drive the worm 41 to rotate and engage with the arc-shaped rack 42 to control the extension and retraction of the gear arm 3.
[0038] As Figure 3 and Figure 4 shown, one end of the worm 41 is sleeved with a nut 8, the nut 8 fixes the worm 41 inside the worm mounting hole 11, the upper end of the worm mounting hole 11 is provided with an internal thread, the nut 8 is provided with an external thread, and the nut 8 is fixed inside the worm mounting hole 11 through the cooperation of the external thread and the internal thread.
[0039] As Figure 3 and Figure 4 shown, the end of the worm 41 connected with the handle 2 protrudes from the housing 5, the top end of the worm 41 is provided with an external spline 44, the top end of the worm 41 is sleeved with an end sleeve 81, the inside of the end sleeve 81 is provided with an internal spline matched with the external spline 44 of the worm 41 to realize fixed connection, one side of the end sleeve 81 is hingedly connected with the handle 2 through a connecting pin shaft 82, the handle 2 rotates around the connecting pin shaft 82, and the connecting pin shaft 82 is provided to enable the handle 2 to adjust the rotation angle and be adjusted to a suitable angle for manual driving; when the handle 2 is buckled inside the handle slot 51, the end sleeve 81 is inserted into the handle 2.
[0040] Example two
[0041] Please refer to Figures 1 to 6 , the utility model provides a window with limiting function.
[0042] As Figure 5 shown, the window comprises a window frame 91 around and a window body 92 hingedly connected with the window frame 91, and glass is embedded in the window body 92.

[0044] When the window body 92 needs to be closed, the driving handle 2 controls the gear arm 3 to retract, and drives the window body 92 to rotate and close; the handle 2 rotates around the connecting pin shaft 82 and is buckled in the handle groove 51, the key 62 rotates and drives the fixed clamping hook 63 to rotate; the fixed clamping hook 63 is inserted into the hook 21, thereby being locked, the key 62 is removed, and others cannot take out the handle 2 and cannot rotate the handle 2, ensuring safety.
[0045] When the window body 92 is opened to the required angle, that is, the handle 2 rotates an integer number of turns, for example, the opening angle is small, and the handle 2 can rotate 1 turn; the opening angle is large, and the handle 2 can rotate 4 turns; the handle 2 rotates around the connecting pin shaft 82 and is buckled in the handle groove 51, the key 62 rotates and drives the fixed clamping hook 63 to rotate; the fixed clamping hook 63 is inserted into the hook 21, thereby being locked, the key 62 is removed, and others cannot take out the handle 2 and cannot rotate the handle 2, ensuring safety.
[0046] As shown in Figure 3 When the handle 2 is opened and rotated, the key 62 is in an inclined state, so that the handle 2 can be pulled out of the handle groove 51 and freely rotated, and the key 62 cannot be pulled out at this time.
[0047] As shown in Figure 2 When the handle 2 is closed and locked, the key 62 is in a vertical state, the fixed clamping hook 63 is inserted into the hook 21, thereby locking the handle 2, and the key 62 can be pulled out at this time.
[0048] In this way, the opening angle of the window body 92 is controlled by rotating the handle 2, and the opening and closing are controlled by locking the key 62, thereby eliminating the safety hazard of the product and effectively solving the defects in the prior art.
[0049] The working principle of the utility model is:
[0050] When the window body 92 is closed, first, the key 62 is used to open the handle 2; secondly, the handle 2 rotates around the connecting pin shaft 82, so that the handle 2 is away from the handle groove 51, and the appropriate angle is found, the handle 2 is reversed, the worm 41 is reversed, the inclined tooth 411 on the worm 41 is engaged with the arc-shaped rack 42, the gear arm 3 rotates around the pin column 7, so that the gear arm 3 rotates clockwise, and the gear arm 3 retracts; thirdly, the pulley 32 slides in the sliding groove 93, drives the window body 92 to rotate and close, and realizes the closing of the window body 92; finally, the handle 2 is retracted and buckled in the handle groove 51, the key 62 is rotated to lock the handle 2, and safety is ensured.
[0051] Similarly, the handle 2 is rotated clockwise to open the window body 92.
[0052] The above embodiment is the preferred embodiment of the present application, but the embodiment of the present application is not limited by the above embodiment, and any change, modification, replacement, combination, simplification made without departing from the spirit and principle of the present application should be an equivalent replacement mode, which is included in the protection scope of the present application.
