[0019] Step 4: The round shell drives the first sliding plate to move, and the first sliding plate drives the extrusion rod to move. During the movement of the extrusion rod, the extrusion rod will come into contact with the bolt to squeeze the bolt, and the extrusion rod will be subjected to the reaction force of the bolt, and the extrusion rod drives the first sliding plate to move toward the inside of the round shell.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the second coupling is arranged between the two first couplings for docking, and the first coupling and the second coupling are stabilized by the arrangement of bolts and nuts. The motor is started, and the motor drives the output shaft to rotate, and the output shaft drives the first ferrule to rotate, and the first ferrule drives the first coupling to rotate, and the first coupling drives the second ferrule to rotate, and the first coupling drives the load shaft to rotate, so that the device performs the output work of the motor. When the first ferrule and the second ferrule rotate at the same time, because the threads of the first ferrule and the second ferrule are arranged in opposite directions and are limited by the cross bar, the first ferrule and the second ferrule will drive the threads The threaded sleeve moves, and the two threaded sleeves move in opposite directions at this time. The threaded sleeve drives the bent rod to move, the bent rod drives the square plate to move, the square plate drives the round shell to move, the round shell drives the first sliding plate to move, and the first sliding plate drives the extrusion rod to move. The extrusion rod will come into contact with the bolt during the movement to squeeze the bolt to prevent the bolt from falling off due to vibration when the motor is output, thereby improving the stability of the device assembly, and the extrusion rod is subjected to the reaction force of the bolt, and the extrusion rod drives the first sliding plate to move toward the inside of the round shell. At this time, the friction rod will pass through the small hole of the extrusion rod, thereby coming into contact with the surface of the bolt, thereby increasing the friction between the two, preventing the bolt from rotating and falling off during work, and further improving the stability of the device.

[0022] (2) In the present invention, during the movement of the square plate, the square plate drives the first rotating rod to move. The first rotating rod is limited by the limiting shell, and the slider drives the second rotating plate to move. The second rotating plate drives the second sliding plate to move. The second sliding plate is limited by the square groove and moves along the trajectory of the square groove. The second sliding plate drives the semicircular block rod to move.

[0023] (3) According to the present invention, when the slider moves upward, the slider drives the vertical rod to move upward, the vertical rod drives the connecting rod to move upward, the connecting rod drives the arc shell to move, the arc shell drives the sliding rod to move, the sliding rod drives the roller to move, so that a plurality of rollers come into contact with the inner wall of the protective shell. When the rollers and the protective shell support each other, a reaction force is generated, so that the vertical rod squeezes the reset spring, the reset spring squeezes the limit shell, the limit shell squeezes the first coupling, and the first coupling squeezes the second coupling, so that the second coupling is always in the center position of the protective shell, thereby improving the stability of the device during operation.

[0024] (4) According to the present invention, when the roller contacts the protective shell, the sliding friction is converted into rolling friction, which reduces the friction force generated when the roller contacts the protective shell, thereby improving the protective effect of the device on the protective shell. The roller is subjected to the reaction force of the protective shell, so that the roller drives the sliding rod to slide toward the inside of the arc shell, the sliding rod drives the vertical bar to move, and the vertical bar drives the blocking plate to move. When the blocking plate moves to one end of the inner wall of the condensation shell, the blocking plate no longer blocks the bent pipe. At this time, the cold air generated by the condenser will enter the inside of the bent pipe, and the cold air will enter the inside of the arc shell through the bent pipe, cooling the outer wall of the roller, preventing the roller from wearing out after entering the inside of the arc shell and generating high-speed friction with the arc shell, thereby improving the service life of the roller.

During the movement of the semicircular block rod 778, it will contact the surface of the nut 755, thereby increasing the friction between the semicircular block rod 778 and the nut 755, preventing the nut 755 and the bolt 754 from falling off during the operation of the device, and further improving the stability of the device.

[0056] When the slider 772 moves upward, the slider 772 drives the vertical rod 781 to move upward, the vertical rod 781 drives the connecting rod 782 to move upward, the connecting rod 782 drives the arc shell 783 to move, the arc shell 783 drives the sliding rod 785 to move, and the sliding rod 785 drives the roller 786 to move, so that multiple rollers 786 come into contact with the inner wall of the protective shell 2. When the roller 786 and the protective shell 2 support each other, the reaction force generated causes the vertical rod 781 to squeeze the return spring 774, the return spring 774 squeezes the limit shell 773, the limit shell 773 squeezes the first coupling 5, and the first coupling 5 squeezes the second coupling 6, so that the second coupling 6 is always in the center position of the protective shell 2, thereby improving the stability of the device during operation.

[0057] When the roller 786 contacts the protective shell 2, the sliding friction is converted into rolling friction, which reduces the friction generated when the roller 786 contacts the protective shell 2, thereby improving the protective effect of the device on the protective shell 2, and the roller 786 is subjected to the reaction force of the protective shell 2, so that the roller 786 drives the sliding rod 785 to slide inside the arc shell 783, the sliding rod 785 drives the vertical bar 788 to move, the vertical bar 788 drives the blocking plate 789 to move, and the blocking plate 789 moves. When it moves to one end of the inner wall of the condensation shell 7810, the sealing plate 789 no longer blocks the curved pipe 7812. At this time, the cold air generated by the condenser 7811 will enter the interior of the curved pipe 7812, and the cold air enters the interior of the arc shell 783 through the curved pipe 7812 to cool the outer wall of the roller 786, thereby preventing the roller 786 from entering the interior of the arc shell 783 and generating high-speed friction with the arc shell 783, which causes the roller 786 to wear, thereby increasing the service life of the roller 786.
