摘要： An over-centre clamp (10) comprises a flexible band (22) having a hinge end (28) and a hooked end (30). The hooked end (30) is adapted to grasp a margin (16) of a first member (12). The over-centre clamp (10) further comprises a lever arm (34) hingedly connected to the hinge end (28). The lever arm (34) has a handle (36) and a pivot link (38). The pivot link (38) has an end adapted for insertion into a socket (20) in a second member (14). This enables the first and second members (12,14) to be clamped together by grasping the margin (16) with the hooked end (30), inserting the pivot link (38) into the socket (20), and rotating the handle (36) away from the band (22) to a point wherein the band (22) is tensioned and bears upon the second member (14). The over-centre clamp (10) includes a retainer (46) connected to the band (22) adjacent the hinge end (28). The retainer (46) is engageable with the lever arm (34) to resist rotation of the lever arm (34) with respect to the band (22) when the lever arm (34) is in an open position wherein the angle between the lever arm (34) and the band (22) is sufficient to ensure that, when the hooked end (30) grasps the margin (16), the pivot link (38) is away from the socket (20).
摘要翻译：过中心夹具（10）包括具有铰链端（28）和钩端（30）的柔性带（22）。钩端（30）适于抓住第一构件（12）的边缘（16）。过中心夹具（10）还包括铰链连接到铰链端（28）的杠杆臂（34）。杠杆臂（34）具有手柄（36）和枢轴连杆（38）。枢转连杆（38）具有适于插入第二构件（14）中的插座（20）中的端部。这使得第一和第二构件（12,14）能够通过用钩端（30）抓住边缘（16）而夹紧在一起，将枢转连杆（38）插入到插座（20）中，并且使手柄 36）远离带（22）到其中带（22）被张紧并承载在第二构件（14）上的点。过中心夹具（10）包括与铰链端（28）相邻的带（22）连接的保持器（46）。当杠杆臂（34）处于打开位置时，保持器（46）可与杠杆臂（34）接合，以抵抗杠杆臂（34）相对于带（22）的转动，其中杠杆臂（34）和带（22）足以确保当钩端（30）抓住边缘（16）时，枢转连杆（38）远离插座（20）。
