Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of calipers, in particular to a stainless steel pipe fitting clamping arm. BACKGROUND

[0002] The stainless steel pipe fitting arm is matched with the jaw, and is the key to ensure firm installation and stable construction during pipe fitting installation. The existing arm cannot guarantee uniform stress during stainless steel pipe installation because the left and right arms rely on the blocking plate pinhole for positioning. When subjected to external force, the arms generate force on the jaw, thereby clamping the pipe. When the left and right arms rotate around the blocking plate pinhole, there is no second positioning hole, and when the stress on the two arms is uneven, the left and right arms will be out of sync during rotation, thereby causing the jaw installed thereon to be misaligned, and causing the pipe to be clamped tightly, leaking and being damaged.
