In use, the inventor finds that, in the adjustment process, due to the acting force of the cable, the cable is tensioned and balanced through the comprehensive acting force of the connecting reinforcing rod 20, the threaded upright post 13 and the motor 16, and in the subsequent adjustment process, due to the very strong acting force between the connecting reinforcing rod 20 and the telescopic upright post 3, the connecting reinforcing rod 20 is difficult to pull out through the action of the light spring 22, so that the fine adjustment is difficult, and although the normal operation can be realized, the conditions that the adjustment cannot be realized and the coil of the first electromagnet 12 is burnt due to heat usually occur in the high strength, so that the applicant further improves the following steps: on one hand, the motor 16 is set to have a fine adjustment mode and a coarse adjustment mode, the fine adjustment mode is a fine adjustment mode in which the motor 16 can rotate forward and backward at a relatively low rotation speed, the coarse adjustment mode is used for driving the telescopic upright 3 to extend and retract so that the cable

diameter of the middle part 23, the first end part 24 and the second end part 25 are respectively sleeved with a first coil and a second coil along the horizontal direction, the middle part 23 is sleeved with a third coil along the vertical direction, the first electromagnet 12 is sleeved with a driving coil, and through the electromagnet with the special structure, the first end part 24 and the coil thereof can be matched with the first electromagnet 12 to increase the connection acting force between the connection reinforcing rod and the connection reinforcing rod, the connecting reinforcing rod can be more smoothly pulled out by increasing the acting force, and the first coil and the second coil can be independently controlled, even if the first coil on the first end part is burnt out, the second coil can enable the first end part to have magnetism, because the whole first end part, the middle part and the second end part are mutually connected and have magnetism transmission, one layer of redundant protection can be added between the first end part and the second end part, the first transverse plate 26 is arranged outside the middle part 23, the first spring 27 is connected outside the first transverse plate 26, the second transverse plate 28 is connected outside the first spring 27, the roller 29 is arranged on the second transverse plate 28, because the middle part 23 is provided with the third coil in the vertical direction, the third coil is matched with the middle part 23 to absorb the first transverse plate 26, because the corresponding permanent magnet is arranged on the first transverse plate 26, and therefore, through the matching action of the third coil, the roller 29 can be extended when needed by the action of the first transverse plate 26, the first spring 27 and the second transverse plate 28, the connection reinforcing rod 20 can be pulled out more smoothly by rolling friction by the action of the roller 29, it should be noted that the connection reinforcing rod 4 is provided with a receiving groove corresponding to the roller, and the roller 29 mainly plays a role of supporting the connection reinforcing hole 4, the diameter of the connection reinforcing rod itself is slightly smaller than that of the connection reinforcing hole, the diameter can be set to be pulled out and entered better, meanwhile, the connection strength is not damaged by the cooperation of the roller, more importantly, the arrangement of the structure can cooperate with the fine adjustment mode of the motor 20, one side end part

the permanent magnet 31, when the connection reinforcing rod needs to be pulled out, the motor 20 enters a fine adjustment mode, the motor 20 enters the positive rotation and the negative rotation of the polar velocity, the movement of the mode can not be that the guy cable is tensioned or the guy cable is not tensioned, and the series of structures are controlled and completed by a controller.
When the connection reinforcing rod 20 enters the connection reinforcing hole 4, the elastic part 30 can enter for pre-alignment through the action of the elastic part 30, the buffer contact of the connection reinforcing rod 20 and the pre-connection reinforcing hole 4 can be realized through the action of the elastic part 30, and the elastic part 30 is compressed more and more closer to the bottom, so that the buffer acting force is larger, the structure is simple but practical, when needed, the elasticity of the elastic part 30 can be further increased through the matching action of the second coil pre-permanent magnet at the second end part, the elasticity can supplement the elasticity loss of the elasticity of the elastic part 30 after the use time is longer, and after the complete contact, the permanent magnet 31 can be compressed in the groove; when the connection reinforcing rod 20 needs to be pulled out, due to reasonable pressure in the sealing of the elastic part 30, the pressure can promote the connection reinforcing rod 20 to be pulled out smoothly, meanwhile, in the pulling-out process, the second coil on the second end part 25 can be used to match with the permanent magnet 31 to further improve the pushing force, and the acting force can exist continuously, so that the pressure sensor can always receive a pressure signal, after the pressure signal is transmitted to the controller, the controller can determine the contact condition between the connection reinforcing rod 20 and the connection reinforcing hole 4, can perform feedback in real time, meanwhile, the controller also controls the first electromagnet 12 to start the adsorption on the connection reinforcing rod 20, and if the corresponding pressure of the pressure sensor signal is not detected to be reduced obviously in preset time, the first coil and the second coil on the first end part and the second end part are started again, further increasing the absorption force between the first electromagnet 12 and the first coil, the second coil and the connection reinforcing rod 20 to enable the pulling-out more smoothly, and simultaneously controlling the motor 16 to enter a fine adjustment mode, in the fine adjustment mode, the motor 16 performs cyclic forward rotation and reverse rotation of polar velocity, and simultaneously controlling the third coil on the middle portion 23 to open to enable the first transverse plate to move upwards and push the first spring and the second transverse plate 28 to move upwards, it should be noted that the forward rotation and reverse rotation do not change the acting force on the cable, or the velocity is not fast enough to change the acting force on the cable, and furthermore, the energizing time of the third coil can be set in cooperation with the forward rotation and reverse rotation of the motor, that is, the energizing time of the third coil is synchronous with the forward rotation or reverse rotation of the motor, that is, that the micro-movement caused by the forward rotation or reverse rotation of the motor can be performed by the first spring, The forces acting on the first and second cross plates and the rollers are offset, so that the connection reinforcing bar 20 can be smoothly pulled out through the above-mentioned series of operations, and even in the case of the seizing, the seizing can be touched through the above-mentioned operations, which is another important point of the present invention.
