[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] Example 1, as Figure 1-5 As shown, this utility model provides a universal joint that is easy to disassemble. The universal joint includes: two connecting rods 1, each with a square groove 2 at one end. A square plate 3 is embedded inside the square groove 2. A screw cylinder 5 is slidably connected through the center of the square plate 3. Both ends of the screw cylinder 5 are slidably connected through the top and bottom inner walls of the square groove 2. A screw rod 6 is threadedly embedded inside the screw cylinder 5. A turntable 7 is fixedly connected to the bottom of the screw cylinder 5 and the top of the screw rod 6. A U-shaped plate 9 is fixedly connected to one end of each square plate 3. A second groove 10 is formed at both ends of the U-shaped plate 9. A cross shaft 11 is provided inside the U-shaped plate 9. A fixing plate 12 is fixedly connected to each of the four ends of the cross shaft 11. Two of the fixing plates 12 are located inside and adapted to the second groove 10. The surfaces of the other two fixing plates 12 are symmetrically provided with first arc-shaped covers 13. A connecting plate 16 is fixedly connected between the two first arc-shaped covers 13.

[0027] The working principle here is as follows: by rotating the screw 5 and the screw 6 in opposite directions, it is possible to easily remove the square plate 3 inside the square groove 2, thereby facilitating the disassembly and replacement of the universal joint. At the same time, after disassembly, the bolts on the arc cover can be removed with tools, allowing for the disassembly and replacement of the internal components of the universal joint, thus achieving the effect of precise component replacement.

[0028] like Figure 1-5 As shown, a first groove 4 is provided on the surface of the connecting rod 1 at the screw cylinder 5, and the turntable 7 is located inside the first groove 4 and is adapted to it; the surface of the turntable 7 is fixedly connected with rotating parts 8; the edges of the U-shaped plate 9 are all rounded; the two ends of the U-shaped plate 9 are provided with second arc covers 18 at the arc groove 14, the surface of the U-shaped plate 9 is provided with screw grooves near the top and bottom, and the surface of the second arc cover 18 is provided with mounting holes near both ends.

[0029] The working principle here is as follows: the first groove 4 allows the turntable 7 inside to rotate easily, and the rotating part 8 can drive the turntable 7 to rotate. The rounded corners of the U-shaped plate 9 can prevent the edge of the U-shaped plate 9 from scratching the user. At this time, the bolt can be inserted through the mounting hole on the second arc cover 18 and embedded in the screw groove.

[0030] like Figure 1-5 As shown, mounting holes are provided at both ends of the first arc cover 13, and the mounting holes on the first arc cover 13 are aligned with each other; the inner arc walls of the second groove 10, the first arc cover 13 and the second arc cover 18 are all provided with arc grooves 14, and the surface of the fixing plate 12 is fitted with and fixedly connected with an annular plate 15, which is located inside the arc groove 14 and rotatably connected to its bearing; both ends of the first arc cover 13 and the second arc cover 18 are rounded; a ball is provided at the center of the cross shaft 11; and a connecting post 17 is fixedly connected between the connecting plates 16 and near the center.

[0031] The working principle here is as follows: the bolts can be inserted through the mounting holes at both ends of the first arc cover 13 to fix the symmetrical first arc cover 13. After installation, the first arc cover 13 and the second arc cover 18 can be limited by the annular plate 15 and the arc groove 14. The ends of the first arc cover 13 and the second arc cover 18 are rounded to prevent scratches to the user. At the same time, the connecting column 17 can make the connecting plates 16 more stable.

[0032] Working principle: When the universal joint needs to be disassembled, the screw barrel 5 and screw rod 6 can be rotated in opposite directions by the rotating part 8, so that the screw rod 6 can be taken out from the inside of the screw barrel 5. Then, the screw barrel 5 can be taken out, which makes it easier to remove the square plate 3 inside the square groove 2. This makes it easier to disassemble and replace the universal joint component between the two connecting rods 1. After disassembly and replacement, the bolts in the mounting holes on the first arc cover 13 and the second arc cover 18 can be removed with tools.
