[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] See also Figure 1-4The embodiment of the utility model provides a fork-type flange flange, including a support plate 1, a first mounting portion 2 is provided on one side of the support plate 1, and two second mounting portions 3 are relatively provided on the side of the support plate 1 away from the first mounting portion 2, the first mounting portion 2 is provided with a spline groove 21 for cooperating with the input shaft of the gearbox, the second mounting portion 3 is provided with an arc groove 31, and the arc groove 31 is provided with a mounting recessed groove 311 cooperating with the shaft head 5 of the cross-axis universal joint, and the second mounting portion 3 is also provided with a clamping member for pressing the shaft head 5 of the cross-axis universal joint into the mounting recessed groove 311.

[0020] The two mounting recesses 311 have limiting protrusions 312 at their opposite ends, the support plate 1 has a recessed hole 11 connected to the spline groove 21 , and the support plate 1 has rectangular recesses 12 symmetrically disposed on both sides of the recessed hole 11 .

[0021] The limiting protrusion 312 and the installation groove 311 form an L-shaped structure. When installing the cross-axis universal joint, two of the shaft heads 5 on the cross-axis universal joint are respectively installed in the two installation grooves 311, and the two shaft heads 5 are located between the two limiting protrusions 312. The limiting protrusion 312 plays a limiting role, preventing the cross-axis universal joint from shaking left and right along the axis of the shaft head 5, thereby ensuring the stability of the connection.

[0022] Specifically, the clamping member includes an arc-shaped pressure plate 4 that cooperates with the shaft head 5. Extension portions 41 are horizontally provided at both ends of the arc-shaped pressure plate 4. The extension portion 41 is connected to the second mounting portion 3 by bolts. The arc-shaped pressure plate 4 and the extension portion 41 are made as one piece.
