    摘要： Some embodiments of the present clamps include a first clamp portion having a first end defining a recess and a second end configured to be coupled to a first structure, a second clamp portion having a first end configured to be coupled to a second structure and a second end configured to be received in the recess of the first clamp portion, and a shear pin configured to secure the second clamp portion relative to the first clamp portion. Some embodiments include a retaining member disposed in the recess. In some embodiments, the recess and/or retaining member is configured to resist shearing of the shear pin if a force is applied to the second clamp portion in a first direction, but not if the force is applied in a second direction. In some embodiments, the first direction is substantially parallel with, but opposite to, the second direction.

    摘要翻译： 本夹具的一些实施例包括第一夹具部分，其具有限定凹部的第一端部和构造成联​​接到第一结构体的第二端部，第二夹具部分具有被配置为联接到第二结构的第一端部， 端部构造成容纳在第一夹持部分的凹部中，以及剪切销，其构造成相对于第一夹持部固定第二夹持部。 一些实施例包括设置在凹部中的保持构件。 在一些实施例中，如果在第一方向上将力施加到第二夹持部分上，则凹部和/或保持构件被构造成抵抗剪切销的剪切，但是如果在第二方向上施加力，则该凹槽和/或保持构件不被施加。 在一些实施例中，第一方向基本上与第二方向平行但相反。
