[0029] In one embodiment, please refer to Figure 1The detection component 4 includes a bracket 401 mounted on the upper surface of the housing 201.

[0030] In one embodiment, please refer to Figure 4 The upper surface of the L-shaped plate 302 has two sliding grooves 5. The inner wall of each sliding groove 5 is slidably connected with a bent plate 501. The two sets of bent plates 501 are fixedly installed on the upper surface of the two connecting plates 301 respectively. By providing the bent plates 501 and the sliding grooves 5, the connecting plates 301 can be moved, so that the connecting plates 301 can slide, making the connecting plates 301 more stable during the sliding process.

[0031] In one embodiment, please refer to Figure 3 Each control board 204 has a guide hole 207 on its right side. A guide rod 208 is slidably connected to the inner wall of each guide hole 207. The left and right ends of the guide rod 208 are fixedly installed to the inner wall of the housing 201.

[0032] In one embodiment, please refer to Figure 1 A control panel 6 is provided above the platform 1. The control panel 6 is located in front of the platform 1, and the device can be easily operated through the control panel 6.

[0033] In one specific embodiment, during use, the oscillator is first placed on the stage 1, and the servo motor 202 is started, causing the servo motor 202 to drive the positive and negative threaded rod 206 to rotate. As the positive and negative threaded rod 206 rotates, it can control the control plate 204 through the threaded hole 205, allowing the control plate 204 to move inside the slide 203. This allows the control plate 204 to pull the L-shaped plate 302 to move, and the L-shaped plate 302 can push the threaded control rod 304 and the threaded tube 305 to push the connecting plate 301. The mechanism moves the connecting plate 301, causing it to push the U-shaped plate 309 and clamping plate 303 to move. This allows the clamping plate 303 to hold the oscillator. As the clamping plate 303 contacts the oscillator, the spring 308 can be compressed to absorb the thrust applied by the connecting plate 301, preventing the oscillator from loosening or shaking. Then, the electric push rod 402 is activated, causing it to push the mounting plate 403 downward. This allows the mounting plate 403 to push the frequency meter body 404 downward, enabling the frequency meter body 404 to inspect the oscillator.
