[0006] In the above-mentioned high-stability universal joint, one end of the positioning rod extends out of the installation slot, and the other end of the positioning rod extends into the installation slot and is connected to the return spring. The positioning rod is extended and retracted at the installation slot under the action of the return spring.
[0007] In the above-mentioned high-stability universal joint, there are four fixing rods, the number of which is the same as the number of the openings, and two positioning components are arranged on each of the fixing rods.
[0008] Compared with the prior art, the two universal mounting parts on the high-stability universal joint are installed through a split universal connecting part. When one of the connecting units connected to the cross shaft is damaged, there is no need to replace the entire universal connecting part, thereby reducing working costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the utility model.
[0010] Figure 2 It is a cross-sectional structural schematic diagram of the utility model.
[0011] In the figure, 1, universal joint mounting part; 2, cross shaft; 3, universal joint; 4, yoke part; 5, connecting unit; 6, fixing part; 7, fixing rod; 8, positioning part; 9, positioning rod; 10, return spring. DETAILED DESCRIPTION
[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 , Figure 2 As shown, the high stability universal joint comprises two universal joint mounting parts 1, the universal joint mounting parts are used to connect the external transmission shaft, the two universal joint mounting parts 1 are both provided with a cross shaft 2, the two universal joint mounting parts 1 are connected via a universal connector 3, two ends of the cross shaft 2 are respectively connected to the universal joint mounting parts 1, and the other two ends of the cross shaft 2 are respectively connected to the universal connector 3, the universal joint mounting part 1 is provided with a yoke part 4 for connecting the cross shaft 2, the universal connector 3 is composed of two connecting units 5, the two connecting units 5 are both provided with a yoke part 4 for connecting the cross shaft 2, and the two connecting units 5 are provided with a yoke part 4 for connecting the two A fixing part 6 for fixed connection, wherein one of the fixing parts 6 is provided with a fixing rod 7 for fixing, and the other fixing part 6 is provided with an opening for the fixing rod 7 to extend into, and a positioning part 8 for positioning the fixing rod 7 is provided on the fixing part 6 and at the position of the opening, and the fixing rod 7 is provided with a positioning assembly for positioning, and the positioning assembly is composed of a positioning rod 9 and a reset spring 10, and the fixing rod 7 is provided with a mounting groove for installing the positioning assembly, and the positioning part 8 is provided with a positioning hole that cooperates with the positioning rod 9, and the positioning rod 9 cooperates with the positioning hole to fix the two connection units 5 to form a universal connection member 3 respectively connected to the two universal mounting parts.
