ABSTRACT:
An angle testing apparatus for testing a angle between a first object and a second object includes a workbench, a fixing pole, a triggering member, a pair of contact poles, a controller, and an indicating assembly. The workbench is used for loading the second object thereon. The fixing pole protrudes up from the workbench. The triggering member has a first contact portion and a second contact portion, and is rotatably mounted to the fixing pole. The first contact portion is used for contacting the mounting portion of the second object. The contact poles are fixed at a special position on the workbench according to the desired angle range, for contacting the second contact portion when the mounting angle is not in the desired angle range. The controller is electrically connected to the fixing pole and the contact poles configured to send a signal based on connecting status between the second contact portion of the triggering member and the contact poles. The indicating assembly is electrically connected to the controller to indicate the testing result according to the signal.
