| 摘要 |
An exemplary test apparatus for a columniform workpiece includes a base plate, a support plate perpendicularly mounted to a top surface of the base plate, a shaft rotatably mounted to the support plate, a contact member mounted the support plate and perpendicularly slidable relative to the support plate, and a test meter. The shaft is configured for mounting the columniform workpiece at a side of the support plate and making the columniform workpiece perpendicularly rotate relative to the support plate. The contact member includes a first end contacting the end surface of the columniform workpiece. The test meter includes a pole with a distal end contacting a second end opposite to the first end of the contact member, the poles' length resiliently adjusting corresponding to the end surface of the columniform workpiece, and a value of the test meter changing corresponding to changes in the length of the pole.
