(4) the supporting sleeve touches a baffle at the upper end of the gripper, the gripper is driven to move upwards along with the rising of the continuous oil pipe, the spline shaft slides upwards in the internal spline guide rail, and when the upper end of the supporting sleeve touches the baffle at the upper end of the gripper, the electric push rod is started to push the gripper to start gripping action, a magnet on one gripper gradually extends into a mounting hole of a supporting pipe body of the self-locking buckle supporting piece, a magnet on the other gripper gradually extends into a mounting hole of a supporting pipe body of the clamping needle supporting piece until the electric push rod confirms that the stroke achieves the gripping purpose, the gripper is recovered, at the moment, a roller in the self-locking buckle supporting piece is sucked back by the magnet, and the self-locking buckle supporting piece and the clamping needle supporting piece are separated and are respectively arranged on the two grippers;
(5) then the industrial control computer controls the servo motor to rotate the semi-gear chassis to an initial position, then the steering engine is controlled to rotate the electric push rod, the hand grips rotate 180 degrees, the hand grips align the hopper at the moment, then the electric push rod pushes the hand grips to push the self-locking buckle supporting pieces into the cross rod of the hopper, the other hand grips push the clamping needle supporting pieces into the cross rod of the other hopper, and the dismounting task of one supporting sleeve piece is completed;
(6) and then the electric push rod and the steering engine restore to the initial positions to wait for the next disassembly of the support suite.
4. The method for dismounting the magnetic buckle type support kit of the downhole coiled tubing according to claim 3, wherein the method comprises the following steps: the method for adjusting the split surface of the supporting sleeve to be parallel to the gripper by the industrial control computer according to the shot picture in the step (4) comprises the following steps: the industrial control computer controls the servo motor, the servo motor drives the gear to rotate through the speed reducer, and therefore the half gear chassis is driven to rotate until the split surface of the supporting sleeve is judged to be parallel to the gripper according to the shot picture.
