[0056] Since the triangular block 156 is connected with the trapezoidal convex block 162 on the back of the pressing piece 161, and the contact surface is inclined, when the triangular block 156 moves, the pressing piece 161 is pushed to adhere to the surface of the motor rotating rod, since the pressing piece 161 has a certain length, the simultaneous pressing of multiple pressing pieces 161 can adjust the motor rotating rod with a certain angle to be horizontal, and the moving route of the triangular block 156 is also limited by the trapezoidal convex block 162, so as to prevent misalignment;

[0057] The pressing piece 161 is connected with the positioning convex block 154 through the curved rod 160, the existence of the positioning convex block 154 provides sufficient activity range for the rotation of the curved rod 160, so when the pressing piece 161 is pushed by the triangular block 156, it rotates around the positioning convex block 154;

[0060] When the rotating rod of the hollow cup motor enters the motor rotating rod abutting ring 15, the motor rotating rod pushes the movable ring 152 to move along the direction of the fixed ring 151, in the moving process of the movable ring 152, the triangular block 156 is pulled to move in the opposite direction of the fixed ring 151 through the transmission rope 155, and the pressing piece 161 is pushed to adhere to the surface of the motor rotating rod, since the pressing piece 161 has a certain length, the simultaneous pressing of multiple pressing pieces 161 can adjust the motor rotating rod with a certain angle to be horizontal;

[0061] When the hollow cup motor support frame 2 moves downward, the fixed block 41 drives the adapter 43 to move downward through the horizontal cross bar 42, so as to change the length of the telescopic rod 44, and at the same time when the telescopic rod 44 becomes shorter, the supporting spring 46 installed on the limiting ring 45 is compressed;

[0062] And the first double-end rotating rod 410 and the second double-end rotating rod 411 are connected together through the center positioning rod 412, and are arranged in a whole staggered quadrilateral structure, two corners of the quadrilateral are respectively determined by the arc-shaped convex block 49 and the main supporting block 413, so that the hollow cup motor supporting frame 2 can be deformed and supported at the same time;

[0063] Finally, other devices to be connected are placed on the movable bearing plate 31, and then the movable bearing plate 31 is directly pushed to move along the direction of the limiting sliding groove 16, the angle of the first transmission rod 33 is changed through the limiting block 32, when the angle of the first transmission rod 33 changes, the second transmission rod 36 is also changed synchronously through the limiting sliding block 34, the second transmission rod 36 rotates around the limiting sliding block 34, so as to push the movable transmission block 37 to move in the opposite direction;

[0064] In the process that the device on the movable bearing plate 31 is connected with the motor rotating rod connecting ring 15, the locking rod 310 on the lengthened extension rod 39 will completely pass through the through hole 414, and finally enter the positioning pipeline 17 on the side of the supporting plate 11, so as to complete the locking of the whole supporting assembly 4.
