[0027] The use method and advantages of the utility model: When the anchor rod conveniently connected to the engineering structure for construction engineering is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, first, the anchor body 101 is inserted into the interior of the engineering structure along the opened groove until it is inserted to a suitable depth. The reinforcement block 102 can greatly improve the overall stability and firmness of the anchor body 101. Then, the slot 17 on one side of the fixing plate 5 is clamped to the outside of the positioning pin 10. At this time, the clamping rod 13 is pulled up, so that the clamping rod 13 drives the positioning plate 14 to compress the spring 15 under the cooperation of the slide groove 12 and the slider 16, and disengage from the inside of the clamping groove 103. At this time, the second nut 3 is rotated, and the threaded cooperation of the second nut 3 and the anchor body 101 is utilized to drive the mounting block 4 to move outside the anchor body 101. At the same time, the second nut 3 drives the limiting block 8 to rotate inside the limiting groove 9 through the annular connecting block 7. Therefore, the second nut 3 cannot drive the mounting block 4 to rotate synchronously while rotating. When the second nut 3 drives After the mounting block 4 moves to the specified position, the clamping rod 13 is released. Under the elastic action of the spring 15, the clamping rod 13 drives the positioning plate 14 to move downward and clamp into the inside of the clamping groove 103, so that the clamping rod 13 and the clamping groove 103 directly form a clamping structure, thereby fixing the second nut 3, solving the problem of the nut loosening caused by the anchor rod body 101 under long-term stress state, greatly improving the safety of the connection between the construction project and the engineering structure, and after fixing, the sealing suction cup 6 is driven by the first nut 2 to move outside the anchor rod body 101, so that the edge of one end of the sealing suction cup 6 is fitted together with the outside of one side of the fixing plate 5, so as to achieve sealing protection of the anchor rod connection structure, avoid the problem of rusting caused by erosion of rainwater at the connection structure, thereby greatly reducing the maintenance cost, and meeting the connection requirements of the construction project and the engineering structure.
