[0002] Truss: A structure formed by connecting rods hinged to each other at both ends. A truss is generally a planar or spatial structure composed of straight rods with triangular units. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with a solid web beam, reduce its own weight and increase its stiffness.

[0003] At present, a truss joint announced in the Chinese patent with the publication number of CN2615481Y belongs to a supporting component in the metal truss production industry. Aiming at the defects of poor bearing capacity and unaesthetic appearance of the truss joint, a new type of joint has been developed. It is composed of components such as main chord members. The feature is that bolts and nuts are fixed on the inner wall of the end of the main chord member, keys are provided on the sliding sleeve, and key grooves are provided on the bolt rod. The characteristics are large bearing capacity, good safety performance and aesthetic appearance. It can be widely used in the construction of billboards, display board frames and electric lighting frames.

[0004] However, different surfaces of the elevator truss joint need to be processed or drilled. When processing the truss joint, a positioning mechanism is required to position the truss joint. However, when different surfaces need to be processed, the truss joint needs to be disassembled and repositioned, and the operation is relatively troublesome. It is not convenient to flip the positioned truss joint. Therefore, we propose a positioning mechanism for the production of elevator truss joints to solve the above problems.
