Embodiment
The present invention is described in further detail with reference to embodiment, but embodiments of the present invention not limited to this.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of strata displacement monitoring location device, including the first hoop 1, the second hoop 2,
Connecting rod 4 that 3rd hoop 3, bottom are hinged on the first hoop 1, top are hinged on secondary bar 5 on the 3rd hoop 3, connection first
The two elastic shrinkage devices 6 and two screw rods 7 of the hoop 3 of hoop 1 and the 3rd, first hoop 1 are provided with four through holes
101, two circular holes 301 and two irregularly-shaped holes 302 are provided with the 3rd hoop 3, between the circular hole 301 and irregularly-shaped hole 302
Every setting, described two one end of elastic shrinkage device 6 connect two circular holes 301 of the 3rd hoop 3, other end connection first respectively
1 corresponding through hole 101 on hoop, the bottom of screw rod 7 passes through the through hole 101 of the first hoop 1, and the other end passes through the 3rd hoop 3
On irregularly-shaped hole 302, correspondence spring 6 and the position of screw rod 7 set jagged 201, first hoop 1 on second hoop 2
Connected with the second hoop 2 by connecting tube 8, the top of connecting tube 8 is provided with the outside of Elastic buckle 801, the top of connecting rod 4
