Tuning fork type quartz crystal piezoelectric vibrating reed

Disclosed is a tuning fork type quartz crystal piezoelectric vibrating reed which comprises a base part and a pair of vibrating arms which are connected with the base part and are symmetrically arranged about the central axis of the base part, the base part extends in the length direction of the vibrating arms to form a pair of dispensing arms parallel to the vibrating arms, and the two dispensing arms are distributed on the two sides of the two vibrating arms. The Tuning fork type quartz crystal piezoelectric vibrating reed is characterized in that the gravity center of the vibrating reed is located on the central axis of the base part, a lightening hole is formed in the base part, and the gravity center of the vibrating reed deviates towards the dispensing position of the dispensing arm by reducing the weight of the base part. The lightening holes are formed in the base part of the vibrating reed, so that the weight of the base part is reduced, the gravity center, located on one side of the base part, of th
