The outer walls of the two guide rods 27 are slidingly connected with the inner walls of the clamping blocks 26. The left end and the right end of the clamp housing 21 are both fixedly connected with receiving blocks 28. The ends of the two clamping blocks 26, which are close to each other, are hingedly connected with the ends of the two second connecting blocks 24, which are away from each other. The inner wall of the shell 1 is slidingly connected with a sliding cylinder 29. The driving assembly comprises a motor 210 fixedly connected with the inner wall of the sliding cylinder 29. The output end of the motor 210 is fixedly connected with a second rotating shaft 211. The inner wall of the second rotating shaft 211 is provided with a limiting groove 212. The inner wall of the limiting groove 212 is slidingly connected with a rectangular shaft 213. The top end of the rectangular shaft 213 is fixedly connected with the bottom surface of the first rotating shaft 22. The outer wall of the second rotating shaft 211 is fixedly connected with two clamping blocks 214. The bottom surface of the shell 1 is provided with a plurality of clamping grooves 215.

[0030] By arranging the clamping mechanism 2, the driving of the motor 210 is realized. The motor 210 is lifted by the hydraulic cylinder 33 to complete the synchronous exchange of the two quartz crystal resonators after the detection of the conveying belt and the spectrum analyzer 34. The synchronous clamping and exchange operation reduces the overall time of clamping and transportation for detection to a certain extent, and ensures that the device can quickly and stably perform the air tightness detection.

[0031] As shown in Figure 2 , Figure 3 and Figure 5 , the detection mechanism 3 comprises a fixing assembly and a detection assembly. The fixing assembly comprises two fixing grooves 31 arranged on the bottom surface of the clamp housing 21. The inner walls of the two fixing grooves 31 are both slidingly connected with a fixing block 32. The bottom surfaces of the two fixing blocks 32 are both fixedly connected with the top surface of the shell 1. The detection assembly comprises a hydraulic cylinder 33 fixedly connected with the inner wall of the shell 1. The output end of the hydraulic cylinder 33 is fixedly connected with the bottom surface of the sliding cylinder 29. The outer wall of the shell 1 is fixedly connected with a spectrum analyzer 34.

[0032] Through the setting detection mechanism 3, realized by using hydraulic cylinder 33 and motor 210 mutual cooperation drive, complete clamping mechanism 2 clamping exchange at the same time, set spectrum analyzer 34 and fixed plate 35 facilitate the device is set in the automatic production line, and use the influence of the external environment on the quartz crystal resonator working state fluctuation, judge its airtightness, further improve the practicability of the device.

[0033] One specific application of the embodiment is: spectrum analyzer 34 is the instrument for studying the frequency spectrum structure of electrical signal, is used for signal distortion degree, modulation system, spectral purity, frequency stability and intermodulation distortion, etc. Signal parameter measurement, can be used to measure some parameters of amplifier and filter circuit system, if the instrument uses digital circuit and microprocessor inside, has storage and operation function;Configuration standard interface, it is easy to constitute automatic test system, aiming at different frequency signals and corresponding filter and detector, then through the synchronous multiplex scanner, the signal is transmitted to the CRT or liquid crystal display instrument for display, the spectrum analyzer can detect the frequency change of the resonator, especially when excited by external or environmental influence, it can display the frequency drift or stability problem, suitable for observing the drift of resonant frequency, especially under different load or environmental conditions.

[0034] By setting the clamping mechanism 2, the driving motor 210 drives the second rotating shaft 211 to rotate, and the second rotating shaft 211 drives the first rotating shaft 22 to rotate through the rectangular shaft 213. Since the clamp shell 21 is fixed and limited by the fixed slot 31 and the fixed block 32, the clamp shell 21 will not be rotated by the acting force. The first rotating shaft 22 rotates in the clamp shell 21, drives the first connecting block 23 to rotate around the first rotating shaft 22, and the first rotating shaft 22 drives the two second connecting blocks 24 hinged thereon to move away from each other.

The guide rod 27 is arranged to limit and guide the sliding of the clamping block 26 in the sliding slot 25. At this time, the two clamping blocks 26 synchronously clamp the quartz crystal resonator detected on the spectrum analyzer 34 and the quartz crystal resonator installed on the conveying belt on the right side of the fixed plate 35, and cooperate with the hydraulic cylinder 33 to drive the sliding cylinder 29 to rise upward on the inner wall of the shell 1. The sliding cylinder 29 is driven by the motor 210 to rise the second rotating shaft 211, and the rectangular shaft 213 slides in the limiting slot 212 under the action of the gravity of the clamp shell 21. At this time, the first rotating shaft 22 cannot rotate under the limiting of the rectangular shape of the rectangular shaft 213, so that the two quartz crystal resonators on the clamp shell 21 are still in the clamped fixed state. The hydraulic cylinder 33 continues to drive the motor 210 to rise, and the two clamping blocks 214 on the second rotating shaft 211 lift the clamp shell 21, drive the fixed slot 31 and the fixed block 32 to move away from each other. At this time, the motor 210 is driven to rotate the clamp shell 21 as a whole around the second rotating shaft 211 through the limiting of the clamping block 214 and the clamping slot 215, and the two quartz crystal resonators clamped on the clamp shell 21 are exchanged.
