[0024] In use, when the operator remotely controls the system through the driving assembly, the inner sleeve rod 3 can slide axially inside the outer sleeve rod 2, and by means of the telescopic action, the inner sleeve rod 3 can be extended out of or retracted into the outer sleeve rod 2, thereby realizing the opening or closing of the window.

[0025] Further, the push-pull assembly comprises a driven bevel gear 101 arranged inside the mounting base 1, a threaded rod 102 extending through the mounting base 1 to the inside of the outer sleeve rod 2 is arranged at the bottom of the driven bevel gear 101; a driving rod 103 is arranged transversely on the mounting base 1, a driving bevel gear 104 is arranged on the driving rod 103, and the driving bevel gear 104 is meshingly connected with the driven bevel gear 101; a sleeve nut 303 is arranged at the top end of the inner sleeve rod 3, and the sleeve nut 303 is threadedly meshingly connected with the threaded rod 102.

[0026] In use, the driven bevel gear 101 and the threaded rod 102 in the pull assembly are used in cooperation, when the driving rod 103 rotates, the driving bevel gear 104 drives the driven bevel gear 101 to rotate, thereby making the threaded rod 102 rotate. Since the sleeve nut 303 threadedly meshing with the threaded rod 102 is arranged at the top end of the inner sleeve rod 3, therefore, with the rotation of the threaded rod 102, the inner sleeve rod 3 will be pushed out of or pulled into the outer sleeve rod 2 accordingly, thereby allowing the user to more accurately control the extension length of the inner sleeve rod 3, thereby ensuring that the window can be stably opened and maintained at the desired use angle, improving the stability of the window opening.

[0027] Further, a connecting head 301 is arranged at the end of the inner sleeve rod 3, a connecting hole 302 is arranged on the connecting head 301, in use, the connecting head 301 and the connecting hole 302 are used to connect the inner sleeve rod 3 with the window frame or other fixed structure, when the inner sleeve rod 3 moves, it can drive the window to perform the corresponding opening and closing action through the connecting head 301.

[0028] Further, the bottom of the outer sleeve rod 2 is provided with a sealing head 201, and the edge of the sealing head 201 is provided with a sealing sleeve 202.

[0031] In use, the control base 4 is provided on one side of the installation base 1, and the control base 4 is internally provided with a horizontally arranged main control bevel gear 401, and the main control bevel gear 401 is connected with the driving bevel gear 104 through a connecting rod, so as to be synchronously rotated. When the operator rotates the operation bevel gear 402 at the bottom of the control base 4, the main control bevel gear 401 will also be rotated due to the meshing relationship between the main control bevel gear 401 and the operation bevel gear 402, which further drives the rotation of the driving bevel gear 104, so as to finally rotate the threaded rod 102 and realize the telescopic action of the inner sleeve rod 3. In this process, the telescopic action of the inner sleeve rod 3 and the outer sleeve rod 2 can be controlled from the remote end. In further use, the user does not need to manually rotate the driving rod 103 to drive the rotation of the driving bevel gear 104, thereby providing a more convenient operation method and providing more operation space. Through the universal joint 305, the operation rod 403 can control and drive the rotation of the operation bevel gear 402 from multiple angles, thereby further improving the use convenience of the device.

[0032] Further, the bottom of the operating rod 403 is provided with a handle 404, and a plurality of anti-skid lines are formed on the surface of the handle 404. During use, the operator can indirectly rotate the operating tooth 402 by holding and rotating the handle 404, thereby affecting the action of the entire window opening mechanism.
