In the actual clamping process, in the initial stage of the rising, the outer side of the movable rod 831 is contacted with the flaring structure at the lower end of the extrusion barrel 2 in the spiral rising process of the rotary barrel 5, at the moment, the movable rod 831 moves inwards under the extrusion of the flaring structure until the clamping piece 832 moves to the innermost side, at the moment, the clamping piece 832 moving in opposite directions forms a clamping state on the outer side of the nut 1211 (can drive the nut 1211 to rotate, and when the clamping piece 832 does not move to the innermost side, the clamping piece 832 does not form a clamping state on the nut 1211, that means that the nut 1211 does not follow rotation), the nut 1211 is effectively connected with the threaded head in the clamping state in the middle stage of the rising, at the end of the rising, when the nut 1211 is tightly attached to the lower surface of the electric cross arm, the movable rod 831 is inserted into the embedded groove 10 under the elastic action at the moment, so that the nut 1211 is not clamped any more (at the moment, the nut 1211 is also connected, the clamping piece 832 is separated from the outer side of the nut 1211 mainly for the purpose that the nut 1211 is not driven to be separated from the threaded head by the subsequent reverse spiral descending of the rotating cylinder 5, the height of the connecting ring 81 is kept unchanged at the front middle stage in the spiral descending process of the rotating cylinder 5, the movable rod 831 is driven to move inwards (but not form a clamping state for the nut 1211) along with the tightening of the connecting rope 833 at the later descending stage, when the rotating cylinder 5 descends to the lowest position (stops rotating), the movable rod 831 is just pulled out of the embedded groove 10 by the connecting rope 833 (although the clamping piece 832 forms a clamping state for the nut 1211 at this moment, the rotating cylinder 5 stops rotating and does not drive the nut 1211 to rotate reversely), a clamping structure does not exist between the connecting ring 81 and the cylinder body, and the connecting ring 81 drives the clamping assembly 83 under the action of the gravity piece 82, the support 84 is lowered and reset as a whole, thereby being separated from the tightened nut 1211 and the threaded head.

The implementation principle of the embodiment is as follows:
s1, sliding and positioning: the sliding frame 1 is sleeved on the electric cross arm and pushed inwards to be close to one nearest mounting hole of the electric rod (the mounting direction of the insulator and the mounting hole is the direction from the electric rod to the far), at the moment, the sliding frame 1 is reciprocally and slowly moved until the upper end of the positioning rod 64 is embedded into the mounting hole, and at the moment, the mounting position is determined;
s2, mounting: inserting an insulator into the mounting hole, positioning two sides of the inserted insulator through a positioning mechanism 9, pressing a positioning rod 64 by a threaded head at the lower end of the insulator in the process of inserting the insulator downwards, enabling the lower end of the positioning rod 64 to be in contact with a rotating assembly 62 after the insertion is finished, enabling the rotating assembly 62 to drive a square plate 63 to rotate, enabling the rotating assembly 62 to only drive a rotating cylinder 5 to rotate due to the fact that the square plate 63 can only lift up and down at a return frame 7, enabling the rotating cylinder 5 to rotate upwards in a threaded mode under the cooperation of threaded connection, enabling a clamping assembly 83 to be gradually closed to form a clamping mode on the uppermost nut 1211 in the rotating process, supporting the bottom of the nut 1211 through a supporting piece 84, and then enabling the nut 1211 to synchronously rotate to be in locking connection with the threaded head of the insulator;
s3, resetting: when the screw thread is tightly attached to the lower surface of the electric cross arm, locking with the insulator is completed at the moment, meanwhile, the clamping assembly 83 is embedded into the embedded groove 10 (moves outwards) under the action of elastic force so as to stop clamping the outer side of the locked nut 1211, then the rotating cylinder 5 is driven to spirally descend by reversing of the rotating assembly 62, (the height of the clamping mechanism 8 is kept unchanged but the locked nut 1211 is not clamped), after the rotating cylinder 5 descends to the initial height, the clamping mechanism 8 descends and resets, and at the moment, the clamping mechanism 8 is positioned below the locked nut 1211 and the screw thread head;
s4, separating: opening the opening plate 11 in the extrusion barrel 2 to push the sliding frame 1 to move outwards, separating the mounted insulator from the application, moving the sliding frame 1 around the mounting hole which is the second closest to the power rod, and repeating the operation to perform locking connection on the current mounting hole;
s5, repeating the operation: and (5) repeating the steps S1-S4 to sequentially install the rest mounting holes.
