Technical Field

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. The nominal diameter is 8-50 mm. It mainly bears tensile stress. Deformed steel bars have greater bonding ability with concrete due to the ribs, and can thus better withstand external forces. They are widely used in various building structures. The quality of steel bars is directly related to the quality of the building structure. Therefore, steel bar strength testing is a very important part of engineering quality inspection.

[0003] Bending resistance is used as a standard for testing the strength of steel bars. During strength testing, the steel bars are tested by bending them. When bending, most of the time, the two ends of the steel bars are limited, and one end moves to drive the steel bars to bend. However, due to the different diameters of the steel bars, the required limit sizes are also different during testing. Traditional testing equipment is not convenient for limiting steel bars of different diameters, and positioning during testing is more cumbersome. Summary of the invention

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The fixed support plate 6 and the top surface of the driven gear 5 are both provided with a fixing frame 8 at the height of the bolt. Each fixing frame 8 is provided with a positioning hole 11 that cooperates with the positioning pin 12 on both sides.
