A test fixture and a test device

Abstract

This invention relates to a test fixture and test apparatus. The test fixture includes a fixed component, a load-bearing component, a transmission component, and a drive component. The load-bearing component and the transmission component are fixedly connected and support the product under test. The transmission component is rotatably mounted on the fixed component. The drive component is mounted on the fixed component and drives the transmission component to rotate, thereby causing the load-bearing component to rotate. The transmission component includes a first transmission member and a second transmission member. The first transmission member is fixedly positioned relative to the load-bearing component. The second transmission member is connected to the output shaft of the drive component. The first and second transmission members are connected by a transmission line, and the axial directions of the first and second transmission members intersect or cross in opposite directions. This invention can reduce the technical problems of conventional technologies, such as difficulty in achieving simultaneous dual-antenna testing, large equipment size, high cost, and inaccurate testing.

Claims
