This action is performed several times. Since the fire alarm will jump when rebounding, the detection stick will not poke the same point on the alarm button several times, and the anti-bias reset convex block prevents the alarm button from completely jumping out of the position of the detection stick for limiting. After repeating this several times, the fire alarm can be removed to complete the detection.

[0018] The beneficial effects of the utility model are: 1. It uses a machine for detection instead of manual detection one by one, so the detection consistency is strong and it is easy to compare and identify defective products. 2. It has a jump detection function. The fire alarm button has multiple pressing points, so the rebound performance of the alarm button at different positions can be detected.
