Reinforcing steel bar deflection deformation detection device

The utility model provides a reinforcing steel bar deflection deformation detection device which comprises a supporting mechanism, the supporting mechanism comprises a square supporting plate arranged on the ground, a bearing sleeve used for testing pressurization strength is installed above the plate face of the square supporting plate, a bearing vertical rod is arranged at the top of a pipe fitting of the bearing sleeve, and placing plates are arranged on the periphery of a rod body of the bearing vertical rod in a sleeved mode. Sliding mechanisms are installed at the four corners of the top of the containing plate through fastening nuts in a threaded mode. The beneficial effects are that through the adoption of the bearing sleeve, the bearing vertical rod and the square supporting plate, in the using stage, the bearing sleeve is not prone to falling off; a part of lifting lead screw structures needing to play a role in bearing and corresponding arc-shaped bearing pieces can be conveniently and uniformly ad
