DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] like Figures 1 to 3 As shown, a coupling frame includes a frame body 2, which has a first circular through groove 21, and the first circular through groove 21 divides the frame body 2 from left to right into a first connecting part 3 and a second connecting part 4, and the first connecting part 3 has a first step portion 31 and a first through hole 32, and three second threaded holes 311 are opened on the surface of the first step portion 31 with the first through hole 32 as the center; three third threaded holes 41 matching the second threaded holes 311 are opened on the left side surface of the second connecting part 4, a second circular groove 42 is opened on the right side surface of the second connecting part 4, and a plurality of fourth threaded holes 43 are opened on the right side surface of the second connecting part 4 along the second circular groove 42 for connection and fixation.
[0020] When the locking nut 31 is engaged with the locking nut 311, the locking nut 312 is engaged with the locking nut 311 and the locking nut 313. When the locking nut 31 is engaged with the locking nut 311, the locking nut 313 is engaged with the locking nut 313.
[0021] like Figures 1 to 3 As shown, each second threaded hole 311 has the same aperture size as each third threaded hole 41 matched thereto, which is conducive to the screw being threaded more smoothly into the second threaded hole 311 and the third threaded hole 41 of the frame body 2, with the same aperture, higher thread connection accuracy, and more reliable and stable assembly.
[0022] like Figures 1 to 3 As shown, each of the second threaded holes 311 and its matching third threaded holes 41 are on the same axis and are used to connect and fix the shaft body to the coupling.
