Abstract
The utility model relates to a clamp for clamping fragile test pieces with protrusions. The clamp comprises a left clamp part, a right clamp part and a beam, wherein the left clamp part comprises a left clamp body and a left clamp head, and the right clamp part comprises a right clamp body and a right clamp head. The clamp further comprises a connecting part connected with parts other than the clamp, a left arm rod, a right arm rod and a spring, wherein the two ends of the left arm rod are in rotary connection with the connecting part and the rear end of the left clamp body respectively, the two ends of the right arm rod are in rotary connection with the connecting part and the rear end of the right clamp body respectively, and the two ends of the spring are connected to the connecting part and the beam respectively. When the left arm rod and the right arm rod are adjusted to rotate towards the interior of the clamp, the spring deforms, and the left clamp head and the right clamp head are separated. When the adjustment of the left arm rod and the right arm rod is stopped, the left arm rod and the right arm rod automatically rotate towards the exterior of the clamp while the spring recovers to the original state, and then the left clamp head and right clamp head conduct clamping automatically. According to the clamp for clamping fragile test pieces with protrusions, automatic clamping of the left clamp head and the right clamp head can be achieved, the problem that fragile test pieces with protrusions can not be clamped is solved, and the accuracy of a detection result is ensured.
