Detailed Description

Referring to fig. 1-6, the present invention provides a technical solution:

a hole reservation device for constructional engineering comprises a cover plate 1, a clamping groove 101 is arranged in the middle of the bottom surface of the cover plate 1, the clamping groove 101 is conveniently clamped with a positioning column 3, so that the cover plate 1 is positioned and installed, the bottom surface of the cover plate 1 is provided with a limit groove 102, the bottom surface of the cover plate 1 is screwed with a bottom plate 2, the top surface of the bottom plate 2 is provided with a through groove 201, the middle part of the bottom plate 2 is fixedly provided with a positioning column 3, the inside of the positioning column 3 is provided with a pulling block 301, the upper part of the pulling block is sleeved with a spring 302, the spring 302 is convenient for expanding the double-layer rod 304, make the fagging 307 be in the biggest limit, 3 top surfaces of reference column rope knots have the nylon rope, and nylon rope upper end rope knots have pull ring 303, draws piece 301 outside to be that annular equidistant structure articulates there are a plurality of double-deck poles 304, and double-deck pole 304 middle part articulates there is slide bar 305, and slide bar 305 outer end articulates there is slide 306, and slide 306 outside is equipped with fagging 307, and spout 308 has been seted up to fagging 307 top surface, and fagging 307 top surface spiro union has spacing slider 309.

Specifically, the limiting groove 102 and the penetrating groove 201 are both cross-shaped structures, so that the pulling block 301 and the supporting plate 307 can conveniently limit and slide.

Furthermore, the pull block 301 is in sliding fit with the positioning column 3, so that the sliding track of the pull block 301 is limited conveniently.

Still further, the outer end of the double-layer rod 304 is hinged with the supporting plate 307, so that the supporting plate 307 can be opened and closed conveniently.

Furthermore, the inner end of the sliding rod 305 is hinged to the positioning column 3, so that the sliding rod 305 can be folded and contracted conveniently.

It should be noted that the sliding seat 306 is slidably engaged with the sliding groove 308, so as to define the moving track of the sliding seat 306.
