[0002] The steel chisel is a commonly used construction tool, especially in road construction in mountainous areas. It is usually driven into soft rock by a sledgehammer to drill a hole, and explosives are loaded into the drilled hole to blast the rock; it is also commonly used to pry rocks. Even today when construction tools are highly developed, the steel chisel is still indispensable. After the steel chisel is cast, it needs to be cut at both ends to make the two ends of the steel chisel relatively flat and to ensure that the length and hardness of the steel chisel meet the production standards.

[0003] After the steel drill is produced, in order to ensure that the steel drill can be used better in the later stage, the hardness of the steel drill needs to be tested, so as to avoid the steel drill from breaking and bending easily during use. In the prior art, the hardness test of the steel drill is generally performed by fixing the steel drill under the hydraulic equipment, and punching the steel drill with a specified pressure set by the hydraulic equipment, so as to achieve the purpose of testing the hardness of the steel drill.

[0004] After searching, publication number CN217638493U discloses a hardness detection device for steel drill production. The device fixes the steel drill vertically and then indirectly resists the steel drill through a telescopic driving member, thereby achieving the purpose of testing the hardness of the steel drill.

[0005] Although the above-mentioned equipment can perform hardness testing on steel chisels, it can only perform positioning testing on steel chisels of the same type, and its applicability is low. Therefore, there is an urgent need for a positioning mechanism that can test steel chisels of various types to increase the efficiency of steel chisel hardness testing. Utility Model Content

[0009] Two sliding sleeves are slidably arranged on the gantry, and the sliding sleeves can slide up and down on the gantry. A movable rod is arranged between the two sliding sleeves, and the sliding sleeve can drive the movable rod to move up and down. A movable plate is arranged on the movable rod; that is, the movable rod can drive the movable plate to move up and down.
