[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0047] Please see Figures 1 to 8 , Figure 1 This is an assembly diagram of the positioning transmission housing provided in the first embodiment of the present invention. The positioning transmission housing 10 includes a housing 11, a rotating wheel 12, and an elastic component 13. The housing 11 is provided with a mounting hole 111 and a groove 112. The rotating wheel 12 is installed in the housing 11 and is provided corresponding to the mounting hole 111. The rotating wheel 12 is also provided with a threaded hole 122 for installing the transmission shaft 21. The elastic component 13 is installed in the groove 112, and the groove 112 communicates with the mounting hole 111 so that the elastic component 13 abuts against the outer wall of the rotating wheel 12 or the outer wall of the transmission shaft 21.
[0048] The elastic component 13 can abut against the plane or corner of the outer wall of the wheel 12, and the elastic component 13 can abut against the plane or corner of the outer wall of the drive shaft 21. The mounting hole 111 is for the drive shaft 21 of the handle 20 to pass through. In this embodiment, the drive shaft 21 can be prismatic. By installing the elastic component 13 in the slot 112 that communicates with the mounting hole 111, the elastic component 13 abuts against the plane of the outer wall of the drive shaft 21, thereby positioning the rotation angle of the drive shaft 21, and thus positioning the rotation angle of the handle 20. The positioning transmission housing 10 may further include a transmission assembly 14 installed in the housing 11. The transmission assembly 14 is pulsatorically connected to the rotating wheel 12 to provide drive for locking and opening doors and windows. The transmission assembly 14 includes a connector 141, a fixing rod 142, and a transmission gear set 143. The fixing rod 142 is used to fix the housing 11. The connector 141 is pulsatorically connected to the rotating wheel 12 and installed on one side of the fixing rod 142. The transmission gear set 143 is installed on the other side of the fixing rod 142 and includes a gear 144 and two rod bodies. 145, one end of rod 145 is provided with a rack that meshes with gear 144. The two rods 145 are respectively arranged on both sides of gear 144 with the rack facing each other. The rotating wheel 12 rotates with the transmission shaft 21 and moves the connecting piece 141 left and right, so that the connecting piece 141 is connected to one of the rods 145, and drives the other rod 145 through gear 144 to realize the drive of locking and opening the door and window. Thus, by rotating the handle 20, the door and window sash is locked or unlocked with the door and window frame through the positioning transmission housing 10. The positioning transmission housing 10 has a mounting hole 111 and a groove 112 in the housing 11. The mounting hole 111 is for the drive shaft 21 of the handle 20 to pass through. A rotating wheel 12 is provided corresponding to the mounting hole 111. The groove 112 is connected to the mounting hole 111 and an elastic component 13 is provided in the groove 112 so that the elastic component 13 abuts against the outer wall of the rotating wheel 12 or the outer wall of the drive shaft 21 to achieve the positioning of the rotation angle of the handle 20. This allows the user to feel the positioning during the opening or closing of the handle 20. There is no need to set a positioning structure in the handle 20 to achieve the positioning of the handle rotation angle, which simplifies the internal structure of the handle 20, simplifies the assembly process and production cost of the handle 20, and helps to reduce the size of the handle 20. This allows the handle 20 to be installed on doors and windows with narrow frame widths, and is suitable for doors and windows of various specifications, with a wide range of applications. The drive shaft 21 is threadedly connected to the threaded hole 122 of the rotating wheel 12, making the connection between the drive shaft 21 and the rotating wheel 12 more stable and reliable.

[0052] Specifically, there are two elastic elements 131, symmetrically arranged relative to the mounting holes 111, so as to abut against the two side planes of the outer wall of the drive shaft 21. The elastic elements 131 can be located on the upper and lower sides of the mounting holes 111 respectively. Correspondingly, there are also two moving blocks 132, and the moving blocks 132 correspond one-to-one with the elastic elements 131 and are connected to each other. There are also two slots 112. Of course, in some embodiments, there may be only one elastic element 131, which is arranged on one side of the mounting hole 111. Correspondingly, there may also be only one moving block 132.
[0053] Preferably, the elastic element 131 can be a spring. After one end of the spring is fixedly installed in the slot 112, the other end of the spring is connected to one end of the moving block 132 so that the other end of the moving block 132 abuts against the outer wall of the drive shaft 21.
[0054] Specifically, one end of the movable block 132 is recessed into the other end face to form a groove for the other end of the elastic member 131 to abut, so as to prevent the elastic member 131 from shifting due to frequent expansion and contraction. The groove contains a protrusion for the end of the spring to be fitted and connected. Of course, in some embodiments, the end of the spring directly abuts against one end face of the movable block 132.
[0055] Specifically, the housing 11 includes a main housing 113 and a cover plate 114 that covers the main housing 113. The mounting hole 111 is provided on the main housing 113, and the cover plate 114 is provided with a through hole 115 corresponding to the mounting hole 111 for the drive shaft 21 or the rotating wheel 12 to pass through.
