Crystal oscillator suitable for different forms of packaging

The crystal oscillator comprises a crystal oscillator mechanism, a mounting hole is formed in the bottom of a mounting groove in the upper end of a base bottom plate, a shaft sleeve is mounted in themounting hole, pins are sleeved with the shaft sleeve, fixing grooves are formed in the bottoms of the middles of the side walls of the two ends of the base bottom plate respectively, and patches arearranged on the fixing grooves. Clamping grooves are formed in the outer walls, parallel to the fixing grooves, of the two sides of the bottom plate respectively, the bottom plate serves as a pin typecrystal oscillator and is bonded and fixed through patches, pins are used for inserting when the bottom plate serves as a pin type crystal oscillator, the clamping grooves are clamped and fixed to clamping pieces on the installation pieces when the mode is not suitable, and therefore the installation purpose is achieved. Smooth installation of the crystal oscillator under different conditions isfully guaranteed, and the cr
