[0002] A high-precision signal analyzer is an instrument used to analyze and measure signal characteristics, capable of accurately acquiring and processing information such as the frequency, amplitude, and phase of signals. It is usually used in research and applications in fields such as electronics, communication, and audio.

[0003] A Chinese patent of Chinese Patent Application CN202321599863.6 discloses a portable wireless signal analyzer. The key points of its technical solution are: by providing a protection mechanism on the analyzer main body for covering the touch screen, and then covering and protecting it after the device is used, preventing it from being directly placed naked in the backpack and coming into direct contact with other instruments and tools in the backpack, thereby ensuring its service life.

An adjusting device 2 is provided on the surface of the signal analyzer body 1. By setting the adjusting device 2, the effect of cleaning the display screen of the signal analyzer body 1 is achieved. It avoids that when the user uses the signal analyzer body 1, since the signal analyzer body 1 uses a liquid crystal touch capacitive screen for operation, a large amount of fingerprints will remain during the operation, and the staff needs to continuously take out the wiping cloth from the bag for wiping, resulting in blurred spots on the screen of the signal analyzer body 1, affecting the clarity and details of the screen display, and the operation of wiping fingerprints is rather cumbersome, thus improving the practicability of the device.

[0030] Next, specifically describe the specific settings and functions of its adjusting device 2 and clamping device 3.

[0031] Refer to Figure 2 、 Figure 3 and Figure 4As shown in the figure, in this embodiment: The adjusting device 2 includes an L-shaped plate 201, and the L-shaped plate 201 is fixedly connected to the surface of the signal analyzer body 1. A long rod 202 is fixedly connected to the inner surface of the L-shaped plate 201. A sliding plate 203 is slidably connected to the arc surface of the long rod 202. A connecting plate 204 is fixedly connected to the surface of the sliding plate 203. A clamping groove is formed on the surface of the connecting plate 204. A cleaning pad 205 is slidably connected to the inner surface of the clamping groove of the connecting plate 204. A handle 206 is fixedly connected to the surface of the sliding plate 203. A limiting rod 207 is slidably inserted into the L-shaped plate 201. One end of the limiting rod 207 is fixedly connected to a blocking block 208. A limiting groove is formed on the surface of the sliding plate 203. By pushing the blocking block 208, the limiting rod 207 is driven to slide in the L-shaped plate 201 until the limiting rod 207 is inserted into the clamping groove of the sliding plate 203. By providing the limiting rod 207, the position of the connecting plate 204 is limited to prevent the cleaning pad 205 from sliding to block the screen of the signal analyzer body 1. A first spring 209 is sleeved on the arc surface of the limiting rod 207. Both ends of the first spring 209 are fixedly connected to the blocking block 208 and the L-shaped plate 201 respectively. The elastic force of the spring drives the limiting rod 207 to slide in the L-shaped plate 201 and automatically insert into the clamping groove of the sliding plate 203, improving the stability of the device. An installation block 210 is fixedly connected to the surface of the connecting plate 204. A baffle 211 is slidably inserted into the installation block 210. An elliptical plate 212 is fixedly connected to one side of the baffle 211. By pulling the elliptical plate 212, the baffle 211 is driven to slide in the installation block 210 until the baffle 211 does not block the cleaning pad 205, facilitating the staff to replace the cleaning pad 205 and maintaining the high cleaning power of the cleaning pad 205. A second spring 213 is fixedly connected to the side of the elliptical plate 212 close to the installation block 210. The other end of the second spring 213 is fixedly connected to the installation block 210. The second spring 213 drives the baffle 211 to slide in the installation block 210 to automatically block the cleaning pad 205, improving the speed of the device.

[0032] Referring to Figure 5 As shown in the figure, specifically, the clamping device 3 includes a setting block 31, and the setting block 31 is fixedly connected to the side wall of the signal analyzer body 1. A bidirectional threaded rod 32 is rotatably connected to the setting block 31. Two clamping plates 33 are threadedly connected to the arc surface of the bidirectional threaded rod 32. A protective pad 34 is fixedly connected to the side of each of the two clamping plates 33 close to each other. One end of the bidirectional threaded rod 32 is fixedly connected to a handle 35. A short rod 36 is fixedly connected to one side of the setting block 31. The clamping plate 33 is slidably connected to the arc surface of the short rod 36. By rotating the handle 35, the bidirectional threaded rod 32 is driven to rotate in the setting block 31. The bidirectional threaded rod 32 drives the two clamping plates 33 to move towards each other. The clamping plate 33 slides on the arc surface of the short rod 36, making the moving path of the clamping plate 33 more stable.

[0033] Working principle: When the staff needs to wipe the screen of the signal analyzer main body 1, by pulling the stopper 208, the limit rod 207 is driven to slide in the L-shaped plate 201 until the limit rod 207 disengages from the inner surface of the card slot of the sliding plate 203. Then, by pulling the handle 206, the sliding plate 203 is driven to slide on the arc surface of the long rod 202. The sliding plate 203 drives the connecting plate 204 to move, and the connecting plate 204 drives the cleaning pad 205 to move. When the cleaning pad 205 needs to be replaced, by pulling the elliptical plate 212, the baffle 211 is driven to slide in the mounting block 210 until the baffle 211 does not block the cleaning pad 205, so as to facilitate the staff to replace the cleaning pad 205 and maintain the high cleaning power of the cleaning pad 205, achieving the effect of cleaning the display screen of the signal analyzer main body 1. It avoids the situation that when the user uses the signal analyzer main body 1, since the signal analyzer main body 1 uses a liquid crystal touch capacitive screen for operation, a large number of fingerprints will be left during the operation process, and the staff needs to continuously take out the wiping cloth from the bag to wipe, resulting in blurred spots on the screen of the signal analyzer main body 1, affecting the clarity and details of the screen display, and the operation of wiping fingerprints is rather cumbersome, thus improving the practicability of the device.

[0034] When the staff needs to reinforce the connecting wire, by rotating the handle 35, the bidirectional threaded rod 32 rotates in the setting block 31. The bidirectional threaded rod 32 drives the two clamping plates 33 to move towards each other. The clamping plates 33 slide on the arc surface of the short rod 36, making the moving path of the clamping plates 33 more stable, achieving the effect of limiting the connecting wire used by the signal analyzer main body 1, and avoiding the situation that the connecting wire falls off and interrupts the signal during the process of the staff moving the signal analyzer main body 1, thus improving the stability of the device.
