[0002] Steel structure is a structure made of steel materials, mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. The welding points of the steel structure skeleton are the more fragile parts of the steel structure skeleton. When the welding quality is not up to standard, cracking and other phenomena are very likely to occur during use, affecting the service life and even causing safety hazards. Therefore, after the steel structure skeleton is completed, the welding points of the steel structure skeleton are generally tested by a welding point detector. The probe is connected to the display, and then the probe is contacted with the welding point to test the welding points of the steel structure skeleton.

[0003] At present, after the steel structure skeleton is built, most of the welding points need to be tested by welding point detector. After using the welding point detector, the probe needs to be disconnected from the display. At this time, the connection between the display and the probe is exposed to the air and dust may enter. The dust may cause poor contact between the probe and the display, and then cause errors in the test results. Therefore, a steel structure skeleton welding point hardness detection device for construction engineering is needed. The connection between the probe and the display can be protected by a protective device to prevent dust from entering the connection between the probe and the display screen, prevent poor contact between the probe and the display screen, and ensure the accuracy of the detection device.
