DETAILED DESCRIPTION
[0026] like Figure 1-8 As shown, a hand-cranked controller for blinds includes a rotating shaft toggle, a longitudinal moving rod 1, a handle 2, and a driving shell, wherein the rotating shaft toggle is arranged at one end of the longitudinal moving rod 1, and the end of the longitudinal moving rod 1 away from the rotating shaft toggle is fixedly connected to the outer circumferential wall of an internal threaded sleeve 3, the longitudinal moving rod 1 is parallel to the axis of the internal threaded sleeve 3, a screw 4 is rotatably arranged in the driving shell, the two ends of the screw 4 are threadedly connected to the inner side wall of the internal threaded sleeve 3, the internal threaded sleeve 3 is slidably connected to the driving shell, and a screw rotation driver is provided on the handle 2, and the screw rotation driver drives the screw 4 to rotate around the central axis of the screw 4.
[0027] In this embodiment, when in use, the rotating shaft 26 of the blade 25 of the shutter is fixedly connected by the rotating shaft toggle device or the blade 25 connected to the shutter is rotated away from the rotating shaft 26, and the rotating shaft of the blade 25 is perpendicular to the screw 4. Then, the screw 4 is driven to rotate by the screw rotation driver. During the rotation of the screw 4, the internal threaded sleeve 3 between the two ends of the screw 4 moves in the axial direction of the screw 4. During the movement of the internal threaded sleeve 3, the longitudinal moving rod 1 is driven to move in the axial direction (length line) of the screw 4. , the movement of the longitudinal moving rod 1 causes the rotating shaft toggle to move up and down. Since the rotating shaft 26 of the blade 25 of the Venetian blind is perpendicular to the longitudinal moving rod 1, when the rotating shaft toggle is fixedly connected to the rotating shaft 26 of the blade 25 of the Venetian blind, the longitudinal moving rod 1 drives the rotating shaft 26 to rotate during its movement; if the rotating shaft toggle rotates to a position of the blade 25 connected to the Venetian blind away from the rotating shaft 26, the rotating shaft toggle pushes the blade 25 or pulls the blade 25, causing the blade 25 to rotate around the rotating shaft 26, thereby realizing the rotation of the blade 25. As is known to all, when the blade 25 of the Venetian blind rotates to an angle of 90 degrees with the plane where the window of the Venetian blind is located, the Venetian blind is fully opened; when the blade 25 of the Venetian blind rotates to an angle of 0 degrees with the plane where the window of the Venetian blind is located, the Venetian blind is fully closed. Therefore, in the present application, the screw rod 4 can be used to control the distance of the longitudinal moving rod 1 moving up and down to control the degree of the angle between the blade 25 and the plane where the window of the shutter is located after rotation, thereby achieving control of the opening degree of the shutter.
[0028] Among them, there are two design methods for the rotating shaft toggle.
[0029] like Figure 1 , Figure 2As shown, when the rotating shaft toggle adopts the first design method: the rotating shaft toggle includes a first driving rod 5, an extension rod 6, a spring universal tube 7, a rotating piece 8, and a first transition rod 9, one end of the spring universal tube 7 is fixed to one end of the longitudinal moving rod 1, and the other end of the spring universal tube 7 is axially fixedly connected to the extension rod 6, the end of the extension rod 6 facing away from the spring universal tube 7 is fixedly connected to one end of the first transition rod 9, and the other end of the first transition rod 9 is fixedly connected to the first driving rod 5, the first transition rod 9 is perpendicular to the first driving rod 5, and at least one rotating piece 8 is rotatably connected between the two ends of the first driving rod 5, and a connecting hole 10 is provided on the end of the rotating piece 8 facing away from the first driving rod 5.
[0030] After such design, the screw rod 4 rotates, driving the internal threaded sleeve 3 to move up and down, thereby making the longitudinal moving rod 1 move up and down. During the process of the longitudinal moving rod 1 moving up and down, the first driving rod 5 is driven to move up and down, thereby making the rotating piece 8 rotate around the rotating shaft 26, thereby driving the blade 25 to rotate, thereby realizing the opening and closing of the shutter. During the rotation of the rotating piece 8, the lateral distance between the first driving rod 5 and the longitudinal moving rod 1 will change slightly. Therefore, a spring universal tube 7 is designed; and the first driving rod 5 is provided for the purpose of providing a plurality of rotating pieces 8, and at the same time, a longitudinal moving rod 1 can control a plurality of rotating pieces 8 at the same time through the first driving rod 5. The connection hole 10 is provided for matching the rotating piece 8 with the rotating shaft 26 of the blade 25 on the shutter during use.

After such arrangement, due to the addition of the driving shaft 13, when in use, the driving shaft 13 is rotatably connected to the blade 25 away from the rotating shaft 26, so that the lateral distance between the second driving rod 11 and the longitudinal moving rod 1 is always equal during the up and down movement of the second driving rod 11, so that there is no need to set the spring universal tube 7.

After such arrangement, the rotation of the handle 2 drives the second bevel gear 15 to rotate, and then drives the first bevel gear 14 to rotate, and the first bevel gear 14 transmits the rotation to the screw rod 4.
[0033] As a preferred embodiment, the drive housing includes a main housing 16 and a sub-housing 17.
