[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a spindle with a special right-angle head that is easy to assemble and disassemble. (Refer to...) Figure 1 and Figure 2 The device includes a spindle body 1, one end of which extends out of the currently installed device. A mounting shaft 3 is coaxially mounted on the end wall of the spindle body 1 extending out of the device. The mounting shaft 3 is connected to the spindle body 1 by welding. The diameter of the mounting shaft 3 is consistent with the diameter of the spindle. A central threaded hole 31 is opened on the end wall of the mounting shaft 3 away from the spindle. The central threaded hole 31 is opened at the axis of the mounting shaft 3. By setting the mounting shaft 3, subsequent drilling, riveting and other processes on the spindle body 1 can be effectively avoided, thereby protecting the integrity and safety of the spindle body 1.

[0027] Reference Figure 1 and Figure 2Based on the relative dimensions of the spindle body 1 and the installation equipment, several extension shafts 4 are installed on the end of the mounting shaft 3 away from the spindle body 1, depending on the actual situation. The extension shafts 4 are coaxially arranged with the mounting shaft 3. An extension stud 41 is provided on the end of the extension shaft 4 facing the central threaded hole 31, and an extension threaded hole 42 is provided on the end of the extension shaft 4 away from the central threaded hole 31. By connecting several extension shafts 4 in sequence, the overall length of the spindle body 1 can be effectively increased, so that the spindle body 1 can adapt to equipment of different specifications and sizes for installation operations.

[0028] Reference Figure 1 and Figure 2 A mounting flange 2 is provided at the end of the mounting shaft 3 or the extended shaft 4 away from the main shaft body 1. A central stud 22 is coaxially provided at the end of the mounting flange 2 near the main shaft body 1. The central stud 22 can be threaded to the inner wall of the central threaded hole 31 or the extended threaded hole 42, thereby realizing the assembly of the mounting flange 2. A surrounding ring 23 is provided at the end of the mounting flange 2 facing the main shaft body 1. The surrounding ring 23 is coaxially provided with the mounting flange 2 and is sleeved on the outer wall of the extended shaft 4 or the mounting shaft 3. A fastener 24 is provided on the outer wall of the surrounding ring 23 and passes through the surrounding ring 23. Both the extended shaft 4 and the mounting shaft 3 have fastening holes 5 for the fastener 24 to enter. In this embodiment, the fastener 24 is a screw, which is used to improve the connection stability between the mounting flange 2 and the extended shaft 4 or the mounting shaft 3 and reduce the probability of loosening.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The mounting flange 2 has several sets of mounting holes 21 on its surface. Each set of mounting holes 21 is distributed along the circumferential direction of the mounting flange 2. The sets of mounting holes 21 are arranged outward from the center of the mounting flange 2 to enable the installation of special right-angle heads 6 of different sizes.

The surface of the mounting flange 2 has a mounting thread hole 26 for threaded connection of the mounting stud 251, so as to realize quick installation and removal of the positioning post 25. By setting the positioning post 25, when installing the special right-angle head 6, it is only necessary to put it on the periphery of the positioning post 25 and then rotate the special right-angle head 6 to align its own hole with the mounting hole 21 on the mounting flange 2, which improves the ease of assembly. In this embodiment, the periphery of the positioning post 25 is provided with anti-slip texture 252 to increase the friction between the special right-angle head 6 and the positioning post 25 to prevent slippage when bolting.

[0031] The implementation principle of a spindle with a special right-angle head that is easy to assemble and disassemble according to an embodiment of this application is as follows: Based on the size of the special right-angle head 6, a positioning post 25 of appropriate size is selected and installed on the surface of the mounting flange 2. The special right-angle head 6 is fitted onto the periphery of the positioning post 25. During the fitting process, the hole of the special right-angle head 6 is aligned with the mounting hole 21 as much as possible. After the fitting is completed, the special right-angle head 6 is rotated to adjust the angle, and the special right-angle head 6 is fixed to the mounting flange 2 with bolts, so as to realize the convenient installation of the spindle body 1 and the special right-angle head 6.
