The second slider 34 drives the positioning block 31 to move through the movable plate 32, so that the end of the positioning block 31 away from the movable plate 32 does not extend out of the positioning tube 29, ensuring that the positioning tube 29 can be inserted into the mounting tube 27 or the anchor rod 6. At this time, the staff drives the mounting plate 28 to move so that the two adjacent positioning tubes 29 are respectively inserted into the corresponding anchor rods 6 or mounting tubes 27, and the positioning block 31 abuts against the inner wall of the anchor rod 6 or the inner wall of the mounting tube 27. When the positioning block 31 moves to one side of the positioning hole 30, the top and bottom of the mounting plate 28 are respectively against the end of the anchor rod 6 or the mounting tube 27 When the two parts abut against each other, the staff releases the second slider 34, and the compression spring 37 drives the second slider 34 to move in the opposite direction. The second slider 34 drives the positioning block 31 to be inserted into the corresponding positioning hole 30 through the movable plate 32, so that the two adjacent anchor rods 6 or the anchor head 3 and the anchor rod 6 located at the bottom are fixedly connected. When the top end of the anchor rod 6 located at the top abuts against the top inner wall of the mounting shell 2, the staff drives the fixing bar 38 to penetrate the mounting shell 2 and the two adjacent positioning holes 30, and limits the position of the mounting shell 2 by the fixing bar 38 to prevent the mounting shell 2 from sliding relative to the anchor rod 6. The staff drives the second screw rod 40 to penetrate the fixing bar 38 and the support plate 39, and the staff respectively sets second nuts 41 at both ends of the second screw rod 40, and the two adjacent second nuts 41 clamp the fixing bar 38 and the support plate 39 to fix the fixing bar 38 relative to the mounting shell 2.
