[0001] The utility model relates to the technical field of joint installation angle detection tooling, in particular to a detection tooling. Background Art

[0002] In the industrial field, there are many components that require gas or oil line joints to be installed on the surface, such as air compressors. Most of the joints are elbow-type and L-shaped. One end of the joint is screwed to the workpiece body, and the other end often needs to be installed at a specified angle. The requirements for the joint installation angle are relatively precise. In the prior art, the installation angle of the joint is limited by an angle detection tool. However, each angle detection tool can often only be applied to one usage scenario and limit one angle. When the requirements for the joint installation angle change according to actual conditions, another angle detection tool is required. The angle detection tool is not adaptable enough, which makes the detection and limitation of the joint installation angle time-consuming and laborious. In view of the emergence of the above problems, the prior art has not solved them well, which has brought troubles to the normal work in this field. Therefore, there is an urgent need for a detection tool to solve the above problems. Utility Model Content
