If the clamping force of the tension clamp is found to be too large or too small, the needle nose clamp can be used to adjust the curvature of the half arc and change the stress to achieve the desired requirement.
If the clamping surface of the tension clamp is found to have gaps or non-parallel, the clamping effect will be affected, and the angle of the clamping surface can be adjusted by the needle nose pliers to maintain a good closing and contact effect.For the combination of weights, you can connect the two hooks together, or you can connect multiple weights in turn.
The pre-tensioning clamp device and the tensile strength performance testing device relate to the technical field of mechanical equipment. The pre-tensioning clamp device includes a first clamping plate, a second clamping plate, a connecting member disposed between the first clamping plate and the second clamping plate, an elastic member and a pre-tensioning nut, the connecting member including the first a connecting member and a second connecting member, one end of the first connecting member is connected to the first clamping plate, and the other end of the first connecting member is detachably connected to the pre-tensioning nut, and one end of the second connecting member and the second clamping plate Connected, the other end of the second connector is detachably connected to the pre-tension nut.
