摘要： An anti-disassembly connector, belonging to the technical field of mechanical design. The anti-disassembly connector comprises a body (1), and the body (1) may comprise a first end surface (9) and a second end surface (10) disposed opposite to each other. The first end surface (9) is provided with a protruding portion, the protruding portion comprising a first protruding portion and a second protruding portion. The first protruding portion comprises a first force receiving surface (2) and a first force relief surface (4), and a projection of the first force relief surface (4) in a first direction is arc-shaped and disposed at an angle relative the first end surface (9). The second protruding portion comprises a second force receiving surface (5) and a second force relief surface (7), and a projection of the second force relief surface (7) in the first direction is arc-shaped and disposed at an angle relative to the first end surface (9). In this way, the first force relief surface (4) and the second force relief surface (7) cannot be clamped when an adjustable spanner is used to unscrew a nut, so that the anti-disassembly connector can prevent disassembly.
