[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0015] Reference Figure 1The utility model provides a kind of slope protection net steel rope anchor rod pull-out force gauge fixed support, including force gauge tray 8, the bottom end of force gauge tray 8 is detachably connected with three legs, three legs are evenly distributed along the periphery of force gauge tray 8, the center of force gauge tray 8 is provided with the through hole for anchor rod, leg includes main leg 4 and auxiliary leg 7, the top of main leg 4 is detachably connected with force gauge tray 8, the top of auxiliary leg 7 is slidably installed in the bottom end inside of main leg 4, a plurality of bolt holes 6 are vertically arranged on auxiliary leg 7, a plurality of clamping holes are vertically arranged on main leg 4, the interval between adjacent two clamping holes is same with the interval between adjacent two bolt holes 6, and main leg 4 and auxiliary leg 7 are fixed by limiting bolt 5.When the length of leg needs to be adjusted, limiting bolt 5 can be removed from corresponding bolt hole 6 and clamping hole, then main leg 4 and auxiliary leg 7 are relatively slid, so that the overall length is adjusted, and after adjustment is completed, limiting bolt 5 is installed in the bolt hole 6 and clamping hole that are realigned, so as to be fixed, since the interval between adjacent two clamping holes is same with the interval between adjacent two bolt holes 6, so each group of main leg 4 and auxiliary leg 7 can be fixed by multiple limiting bolts 5, so as to ensure the support strength of leg.
