[0019] The mounting mechanism includes a mounting seat 8, a mounting block 12 and a fixing component. The mounting seat 8 is installed on both sides above the mounting plate 3. The mounting seat 8 is provided with a mounting block 12 inside. One end of the mounting block 12 is connected to the outer side of the shell 5. The inner diameter of the mounting seat 8 is larger than the outer diameter of the mounting block 12. A clamping structure is formed between the mounting seat 8 and the mounting block 12. The fixing component includes a movable plate 9, a pull ring 10, a fixing pin 11 and a fixing hole 13. The fixing hole 13 is opened inside the mounting block 12. The movable plate 9 is installed on the outer side of the mounting seat 8. A pull ring 10 is installed on one side of the movable plate 9. A fixing pin 11 is installed on the other side of the pull ring 10. One end of the fixing pin 11 extends to the inside of the fixing hole 13. The mounting seat 8 Four mounting seats 8 are arranged above the mounting plate 3, and the four mounting seats 8 are symmetrically distributed above the mounting plate 3. When the constant temperature crystal oscillator body 4 needs to be inspected and repaired, the pull ring 10 is pulled to extract the fixing pin 11 from the inside of the fixing hole 13. At this time, the mounting block 12 can be taken out from the inside of the mounting seat 8, and the shell 5 can be removed to inspect and repair the constant temperature crystal oscillator body 4. After the inspection and repair is completed, the mounting block 12 is placed into the inside of the mounting seat 8, and the fixing pin 11 is inserted into the inside of the fixing hole 13 after being accommodated, so as to limit the position of the shell 5 and complete the convenient installation of the shell 5. The shell 5 can be conveniently disassembled and installed, making it more convenient and quick to inspect or maintain the constant temperature crystal oscillator body 4, thereby greatly improving the convenience of the constant temperature crystal oscillator when in use.

[0020] The shock absorbing mechanism includes a damper 14, a telescopic spring 15, a limiting hole 16 and a limiting rod 17. The damper 14 is installed at the four corners of the top of the base plate 1. The outer wall of the damper 14 is sleeved with a telescopic spring 15. The top of the damper 14 is connected to the bottom end of the mounting plate 3. The limiting holes 16 are opened at both ends of the base plate 1. The limiting rod 17 is penetrated inside the limiting hole 16. The top of the limiting rod 17 is connected to the bottom end of the mounting plate 3. When vibrated, the telescopic spring 15 is acted upon by the elastic force. With the cooperation of the damper 14, the limiting holes 16 and the limiting rod 17 are used to limit the mounting plate 3, so as to perform a buffering treatment on the mounting plate 3, and then perform a shock absorbing treatment on the constant temperature crystal oscillator body 4, so that the shock absorbing effect of the constant temperature crystal oscillator body 4 is better, so that the effect of the constant temperature crystal oscillator body 4 when in use is better, thereby greatly improving the practicality of the constant temperature crystal oscillator when in use.

[0022] Working principle: When the constant temperature crystal oscillator body 4 is in use, the constant temperature crystal oscillator body 4 is installed through the pin 2 and effectively connected to the circuit. When the constant temperature crystal oscillator body 4 is working, the heat is transferred to the shell 5, and the shell 5 uses the heat dissipation fins 7 to dissipate heat. At the same time, the heat dissipation holes on the shell 5 can also be used to dissipate heat, so that the heat dissipation effect of the constant temperature crystal oscillator is better. When it is vibrated, the telescopic spring 15 is acted on by the elastic force. With the cooperation of the damper 14, the limiting hole 16 and the limiting rod 17 are used to limit the mounting plate 3, thereby buffering the constant temperature. The crystal oscillator body 4 is subjected to shock-absorbing treatment, so that the shock-absorbing effect of the constant temperature crystal oscillator body 4 is better. When the constant temperature crystal oscillator body 4 needs to be inspected and repaired, pull the pull ring 10 to withdraw the fixing pin 11 from the inside of the fixing hole 13. At this time, the mounting block 12 can be taken out from the inside of the mounting seat 8, and the shell 5 can be removed to inspect and repair the constant temperature crystal oscillator body 4. After the inspection is completed, the mounting block 12 is placed into the inside of the mounting seat 8. After being accommodated, the fixing pin 11 is inserted into the inside of the fixing hole 13 to limit the position of the shell 5, thereby completing the convenient installation of the shell 5.
