Title:

SPRING CLAMP

Document Type and Number:

WIPO Patent Application WO/2012/079234

Kind Code:

A1

Abstract:

A spring clamp includes a first main body (10), a second main body (20), a first pivot component (6) and a locking mechanism. The first main body (10) includes a holding part (102) and a clamping part (101), the second main body (20) includes a holding part (202) and a clamping part (201), and the first main body (10) and the second main body (20) are pivotally connected with each other by the first pivot component (6). The locking mechanism is composed of at least one pair of friction parts (31, 32), the first friction part (32) is arranged on the first main body (10) and includes a first friction component (322); and the second friction part (31) is arranged on the second main body (20) and includes a second friction component (301). The first and the second friction components compose a friction component pair and serve as lock by mutual friction. The friction component pair can rub with each other in a plane perpendicular to the axis of the first pivot component (6). There is little abrasion loss between the friction component pair, so that the spring clamp can be used reliably in long time.
