[0020] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, a cost-effective and convenient transmission shaft assembly includes an intermediate shaft 1, one end of which is connected to a first universal joint 2, and the other end of which is connected to a second universal joint 3. The first universal joint includes a housing, which includes a first housing 41 and a second housing 42 that are detachably connected, and also includes an opening groove 420 located axially in the second housing, which is exposed when the first housing is removed; a channel 411 located inside the second housing, which has a structure that is wider at one end and narrower at the other end, with the wider end facing the opening groove; a star-shaped sleeve 11 integrally formed with the intermediate shaft and located inside the second housing; and a retainer 5 located between the star-shaped sleeve and the second housing, wherein the retainer is provided with a rolling element 51 that cooperates with the star-shaped sleeve and the channel. The housing has a channel with a wider end and a narrower end. The wider end faces the side where the first housing is located, which is the side where the opening slot is located after the first housing is removed. The intermediate shaft is inserted from the opening slot side during installation for easy assembly. After insertion, the first housing is installed, which also serves as a limit to prevent it from coming out. At the same time, the intermediate shaft and the star-shaped sleeve are integrated for easy assembly.

[0021] In this embodiment, as shown in the figure, the rolling element is a steel ball.

[0022] In this embodiment, as shown in the figure, the first housing and the second housing are connected by fasteners. They can be connected using screws or other mounting methods.

[0023] In this embodiment, as shown in the figure, the second housing includes a threaded hole 422, and the first housing has a mounting hole opposite to the threaded hole. The fastener is a screw 414, which passes through the mounting hole and connects to the threaded hole. Disassembly and assembly are achieved using screws, making installation relatively convenient.

[0024] In this embodiment, as shown in the figure, the first housing is provided with a recess 412 communicating with the mounting hole. The screw includes a head and a shank. The head is disposed in the recess, and the shank is threadedly connected to the threaded hole. Furthermore, after installation, the screw will not protrude outside the housing, i.e., it is disposed within the recess, resulting in a more compact overall structure.

[0025] In this embodiment, as shown in the figure, a dust cover 6 is also included. One end of the dust cover is connected to the second housing, and the other end is connected to the intermediate shaft. This prevents foreign objects from entering the housing.

[0026] In this embodiment, as shown in the figure, the inner wall of the second housing is provided with six channels.
