When the positioning rod 2 and the mounting rod 41 pass through the steel frame framework, the abutting plate 42 is attached to the mounting rod 41 so that the abutting plate 42 cannot collide with the steel frame framework. After the positioning rod 2 and the mounting rod 41 pass through the steel frame framework, the driving piece 7 is started again to enable the abutting plate 42 to rotate 90 degrees relative to the mounting rod 41, so that the abutting plate 42 can be attached to the inner die plate. Then the mounting rod 41 and the abutting plate 42 are abutted against the inner template, the marking piece 3 on the mounting rod 41 is marked on the screw hole of the inner template, and then drilling is carried out.

And then the outer template is installed, the positioning rod 2 is rotationally disassembled relative to the handle 1 and the installation rod 41, the threaded plug-in block 5 of the handle 1 is reinserted and is in threaded connection with the threaded sleeve 6 of the installation rod 41, the threaded plug-in block 5 of the installation rod 41 is reinserted and is in threaded connection with the threaded sleeve 6 of the positioning rod 2, and meanwhile the marking piece 3 is disassembled relative to the installation rod 41 and is reinstalled on the positioning rod 2. The positioning rod 2 is inserted into the screw hole of the inner template until abutting against the outer template, and the abutting plate 42 is attached to the inner template. Because the installed inner template is in a vertical state, the abutting plate 42 is attached to the inner template, so that the positioning rod 2 can be confirmed to be in a horizontal state, and the screw hole positions of the outer template are marked by the marking piece 3, so that screw holes formed on the inner template and the outer template are aligned, and the opposite-pulling screw can be horizontally penetrated through the inner template and the outer template.

Referring to fig. 1 and 2, the mounting bar 41 is provided with a mounting slot 411, and the opening direction of the mounting slot 411 is perpendicular to the axis of the mounting bar 41. The driving member 7 includes an electric push cylinder 71 and a slider 72, the electric push cylinder 71 is hinged to a groove wall of one side of the mounting groove 411 away from the marker member 3, and a rotation plane of the electric push cylinder 71 relative to the mounting rod 41 is parallel to a rotation plane of the abutment plate 42 relative to the mounting rod 41.

Referring to fig. 1 and 2, a side wall of the abutting plate 42 far from the marker 3 is provided with a sliding groove 421, the length direction of the sliding groove 421 is parallel to the rotation plane of the abutting plate 42 relative to the mounting rod 41, and part of the sliding groove 421 is clamped and slides in the sliding groove 421. The drive shaft of the electric push cylinder 71 is hinged to the side wall of the slider 72 perpendicular to the abutment plate 42.

The driving shaft of the electric push cylinder 71 extends out to push the sliding block 72 to slide relative to the abutting plate 42 so as to push the abutting plate 42 to rotate relative to the mounting rod 41 until the included angle between the abutting plate 42 and the mounting rod 41 is 90 degrees, so that the abutting plate 42 can be attached to the inner die plate to confirm that the positioning rod 2 and the mounting rod 41 are in a horizontal state.

The electric push cylinder 71 is arranged in the mounting groove 411, so that the space where the electric push cylinder 71 is located is reduced, and the abutting plate 42 can be attached to the mounting rod 41 more, so that the electric push cylinder 71 and the abutting plate 42 are not easy to collide with the steel reinforcement framework when the positioning rod 2 and the mounting rod 41 penetrate through the steel frame framework.

The driving shaft of the electric push cylinder 71 is hinged to the side wall of the slider 72 perpendicular to the abutting plate 42, so that the distance between the driving shaft of the electric push cylinder 71 and the abutting plate 42 is reduced, the abutting plate 42 can be further attached to the mounting rod 41, and the possibility that the abutting plate 42 is abutted against the steel reinforcement framework when the positioning rod 2 and the mounting rod 41 penetrate through the steel frame framework is further reduced.

Referring to fig. 2 and 3, for increasing the convenience and accuracy of marking and punching the screw hole position, the marking element 3 includes a magnetic sheet 31 and a magnetic block 32 adsorbed on the magnetic sheet 31, and the magnetic block 32 is fixedly connected with a pigment coating 9, in this embodiment, the pigment coating 9 is a sponge sheet impregnated with pigment.
