[0144] The spring 20 is sleeved on the outside of the telescopic rod 19 and is located on the inside of the rotating frame 16 .

[0145] In the actual application of this embodiment, the threaded rod 46 can provide support for the push ring 45 by using the thread under the support of the T-plate 8, the push ring 45 can provide support for the guide ring 44, the guide ring 44 provides a through channel for the push rod 43, and the guide ring 44 can provide a moving guide for the push rod 43. The telescopic rod 19 can provide a limiting effect for the spring 20 under the support of the rotating frame 16 to prevent the spring 20 from bending. The spring 20 is elastic and can shrink and deform under the action of external force. It will rebound after the external force disappears, and can provide support for the frame 21.

[0146] The staff can control the electric rod 27 to continue to extend according to the actual needs, so that the electric rod 27 moves upward through the L plate 30, the fixed rod 31, the motor 32, the rotating shaft 33, the turntable 34, the rubber ring 35 and the diamond plate 36 under the action of external force, so that the rubber ring 35 fits with the threaded rod 46, and at the same time, the semicircular block 39 will use the reaction force to push the tough plate 38 under the resistance of the bracket 25 and the switch 26, so that the tough plate 38 is squeezed and deformed under the support of the vertical plate 48 and the L plate 30, so that the semicircular block 39 moves in the direction close to the L plate 30, thereby preventing the semicircular block 39 and the switch 26 from affecting the continued upward movement of the L plate 30.

[0147] When the rubber ring 35 is fitted with the threaded rod 46, the staff can start the motor 32 as needed, so that the motor 32 drives the turntable 34 and the rubber ring 35 to rotate together through the rotating shaft 33. At the same time, it is necessary to operate the clamp 7 to release the clamping of the end of the stair column away from the three-jaw chuck 11, so that the rubber ring 35 uses the rotational power and friction force to push the threaded rod 46 to rotate, so that the threaded rod 46 uses the rotational power and the thread to push the push ring 45 to move in the direction close to the three-jaw chuck 11. At the same time, the push rod 43 provides a resistance and limiting effect for the push ring 45 through the guide ring 44 to prevent the push ring 45 from rotating together with the threaded rod 46. At the same time, when the clamp 7 adjusts the clamping, it will drive the clamp plate 40 and the push rod 43 to move together, so that the push rod 43 passes through the guide ring 44 to move When the guide ring 44 moves, the push ring 45 will drive the guide ring 44 under the push of the threaded rod 46, so that the guide ring 44 uses external force to push the shift plate 41 through the push rod 43 along the clamp plate 40 to move in the direction close to the three-jaw chuck 11. At the same time, the shift plate 41 will push the clamp seat 42 and the clamp head 47 to move together in the direction close to the three-jaw chuck 11 under the action of external force, so that the clamp head 47 is adjusted to move to the twisting stop position of the stair column, and then the clamp 7 is controlled to clamp, so that the clamp 7 uses the clamping end to drive the clamp plate 40, the shift plate 41, the clamp seat 42 and the clamp head 47 to clamp the stair column to the appropriate position, and then the motor 10 is controlled to drive the three-jaw chuck 11 to rotate, so as to twist and bend different length sections of the clamped stair columns, thereby improving the twisting flexibility and diversity.

[0148] Working principle: the support frame 1 provides a supporting structure for the entire device. The three-jaw chuck 11 and the clamp 7 on the support frame 1 are respectively located at the two ends of the stair column to clamp the stair column. A fixed plate 2 is installed on one side of the support frame 1 to fix the equipment at the work site. The guide rod 49, guide plate 6, screw 5 and the like in the device work together to realize the translation of the clamp 7 and adjust the clamping position of the stair column. During operation, the electric rod 27 pushes the cone rod 28 through its telescopic function, and further drives the L rod 29 to rotate or move it. This system ensures that the stair column is in the correct twisting position, and provides safety protection through protective parts to prevent splashes from leaking during operation. The electric heating pipe 24 and the shield 23 work together. During operation, the electric rod 27 pushes the shield 23 and the electric heating pipe 24 to cover the stair column and preheat it. The design of the shield 23 can effectively protect the operator from high temperature. When moving, the switch 26 is triggered to control the electric heating pipe 24 to be energized for heating. The twisting operation is completed by the rotation of the three-jaw chuck 11.

[0149] The staff controls the motor 32 on the device to drive the three-jaw chuck 11 to rotate, thereby driving one end of the stair column to rotate. The other end of the stair column is fixed by the clamp 7 to form a torsional force on the metal column. In order to ensure the flexibility of the twisting process, the clamp 7 and the clamp 47 can move along the guide rod 49 of the support frame 1, so that stair columns of different lengths can be twisted at multiple positions, increasing the flexibility and diversity of the process.

[0150] The torque limiter is responsible for controlling the position and accuracy of the twisting. The system moves the push ring 45 and the clamp 47 along the direction of the fixture 7 through the coordinated action of the screw 5, the push rod 43, the guide ring 44 and other transmission parts to ensure that the twisting position of the stair column is accurate.

[0151] The clamping member is responsible for adjusting and fixing the position of the stair column during the twisting process to prevent movement. During the entire operation process, the push plate and clamping plate 40 of the clamping member are pushed by the threaded rod 46 to drive the entire clamping system to lock the twisted part of the stair column, further improving the stability of the working process. The various parts of the device provide additional support and buffering through springs 20, telescopic rods 19 and other components. During operation, the electric rod 27 pushes other components to lift or move, while the semicircular plate 22, rotating frame 16 and other components provide support and guidance for the rotation of the equipment through mechanical design.

[0152] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
