Columnar low-frequency quartz crystal resonator

The invention belongs to the technical field of electronic components, and particularly relates to a columnar low-frequency quartz crystal resonator which comprises a shell and a resonance assembly. The resonance assembly comprises a quartz wafer, two groups of leads, a check ring and a base; the shell is movably connected to the base in a clamped mode, the check ring is connected with the base in a screwed mode, and the check ring is located on the outer side of the shell; the base is further provided with a sealing column, the sealing column is located at the central axis position of the base, and the sealing column movably penetrates through the base and is connected into the base in a clamped mode; and a third clamping groove is further formed in the lower end of the base, and the lower end of the sealing column is elastically connected with the third clamping groove through a spring piece. By means of the arrangement, vacuumizing operation and nitrogen filling operation can be conducted in the shell, the
