| 1. An angle testing apparatus for testing whether a mounting angle between a first object and a second object is in a desired
angle range or not, the second object having a mounting portion for mounting the first object, the angle testing apparatus
comprising:
a workbench configured for loading the second object thereon;
a fixing pole extending up from the workbench;
a triggering member rotatably mounted to the fixing pole, with a first contact portion and a second contact portion located
at opposite sides of the fixing pole, the first contact portion configured for contacting the mounting portion of the second
object;
a pair of first and second contact poles fixed at predetermined positions on the workbench respectively according to a minimum
value and a maximum value of the desired angle range, for contacting the second contact portion of the triggering member when
the mounting angle is not in the desired angle range;
a controller 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 when the second object is moved on
the workbench; and
an indicating assembly electrically connected to the controller to indicate the testing result according to the signal.
