[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a handheld spectrum analyzer, comprising an analyzer body 1, a touch screen 2 on one side of the outer wall of the analyzer body 1 for providing a human-machine interface to visualize spectrum data and set parameters, an RF interface 3 on one side of the outer wall of the analyzer body 1 for connecting an external antenna or signal source to input and output high-frequency signals, control buttons 4 on the upper surface of the analyzer body 1, and a switching assembly on the other side of the outer wall of the analyzer body 1. The switching assembly includes a first rotating shaft 5 and a second rotating shaft 8. One end of the first rotating shaft 5 is fixedly connected to one side of the outer wall of the analyzer body 1, and a fixing plate 6 is rotatably connected to the outer wall of the first rotating shaft 5. A fixing block 13 for providing a mounting frame for clamping the assembly is fixedly connected to one side of the outer wall of the fixing plate 6. A clamping assembly is provided between the fixing block 13 and the first rotating shaft 5 for clamping. The assembly includes a locking rod 18 and a locking groove 19 for locking the angle between the fixed plate 6 and the rotating shaft 5. The outer wall of the locking rod 18 is slidably connected to the inside of the fixed block 13. The locking groove 19 is located on the outer wall of the rotating shaft 5. One end of the locking rod 18 is slidably connected to the inner wall of the locking groove 19. The other end of the locking rod 18 is fixedly connected to a lever 15. The outer wall of the lever 15 is symmetrically provided with sliders 17. The inner wall of the fixed block 13 is symmetrically provided with grooves 16. The grooves 16 cooperate with the sliders 17 to achieve sliding limit and guidance, thereby limiting the movement trajectory of the lever 15 and the locking rod 18, preventing the lever 15 from shifting laterally, and ensuring that the locking rod 18 can be accurately aligned with the locking groove 19. The outer wall of the slider 17 is slidably connected to the inner wall of the groove 16. The fixed block 13 is provided with a spring 14. One end of the spring 14 is fixedly connected to one side of the inner wall of the fixed block 13, and the other end of the spring 14 is fixedly connected to one side of the outer wall of the lever 15.

[0030] Specifically, the rotating shaft 5 rotates in conjunction with the fixed plate 6. The fixed plate 6 can rotate freely around the axis of the rotating shaft 5, providing a rotational basis for switching the equipment from handheld mode to tabletop support mode, meeting the angle adjustment needs under different usage scenarios. The spring 14, together with the lever 15 and the locking lever 18, achieves elastic reset. When the lever 15 is turned, the spring 14 is compressed and stores elastic potential energy. When the lever 15 is released, the spring 14 rebounds and releases the potential energy, pushing the lever 15 to drive the locking lever 18 to move, thereby realizing the function of the locking lever 18 automatically locking into the slot 19 without manual pushing of the locking lever 18, improving the convenience of operation. The locking lever 18, together with the slot 19, achieves angle locking. One end of the locking lever 18 can slide into the inner wall of the slot 19, and the other end is connected to the lever 15. When the locking lever 18 is locked into the slot 19, the fixed plate 6 is fixed at the current rotation angle, preventing the fixed plate 6 from rotating on its own during use and ensuring the structural stability of the equipment.

[0031] Reference Figure 2 , Figure 3 and Figure 5 A mounting block 7 is fixedly connected to the other side of the outer wall of the fixed plate 6. The inner wall of the mounting block 7 is rotatably connected to the outer wall of the second rotating shaft 8. A threaded rod 20 is threadedly connected to the inner wall of the mounting block 7. The outer wall of the second rotating shaft 8 is evenly provided with slots 21. One end of the threaded rod 20 is set in the inner wall of the slots 21. A connecting plate 9 is fixedly connected to the outer wall of the second rotating shaft 8. A bracket 10 for supporting the handle 11 is fixedly connected to one side of the outer wall of the connecting plate 9. The handle 11 is fixedly connected to one side of the outer wall of the bracket 10. An anti-slip sleeve 12 is fitted on the outer wall of the handle 11. The anti-slip sleeve 12 is made of rubber and its function is to increase the friction between the handle 11 and the operator's hand, while improving the softness when holding it, preventing the handle 11 from slipping due to sweaty hands, and preventing the handle 11 from sliding when it is in contact with the table when it is used for support, thus ensuring the stability of the support.

[0032] Specifically, the mounting block 7 works with the rotating shaft 28 and the threaded rod 20 to provide rotational support and angle locking. The inner wall of the mounting block 7 provides rotational support for the rotating shaft 28. At the same time, the mounting block 7 has a threaded hole that works with the threaded rod 20, thereby ensuring that the rotating shaft 28 can rotate stably to adjust the angle of the connecting plate 9. This allows the connecting plate 9 to be locked at different rotation angles by inserting one end of the threaded rod 20 into the slot 21 at different positions, ensuring the stability of the bracket 10 when it is supported.

[0033] Reference Figure 1 and Figure 6The analyzer body 1 has a storage compartment 22 fixedly connected to its lower surface. A parts box 23 and a cable box 26 are slidably connected to the inner wall of the storage compartment 22. The parts box 23, together with the storage compartment 22 and the partition 25, enables the classified storage of small parts. The cable box 26, together with the storage compartment 22 and the winding rod 28, enables the neat storage of cables. A handle 1 24 is fixedly connected to one side of the outer wall of the parts box 23. A partition 25 is provided on the inner wall of the parts box 23 to divide the internal space of the parts box 23 into multiple independent areas. A handle 27 is fixedly connected to one side of the outer wall of the cable box 26. A winding rod 28 is fixedly connected to the bottom of the inner wall of the cable box 26. A cable clamping groove 29 is opened on the outer wall of the winding rod 28. The cable clamping groove 29 is used to fix the end of the cable wound on the winding rod 28, thereby preventing the cable from loosening and falling off the winding rod 28 due to vibration or movement during storage or carrying, and ensuring that the cable always remains in a neat wound state.

[0034] Specifically, handle 24 and handle 27 are fixed to the outer walls of parts box 23 and cable box 26 respectively, so as to facilitate users to pull out the box for taking out and putting in, improving the convenience of use. The partition 25 is used to divide the internal space into multiple areas to realize the classified storage of different types of small parts, which is convenient for quick access and management. The winding rod 28 is used to neatly wind the cable and fix the end, prevent the cable from tangling and knotting, extend the service life of the cable and improve the storage efficiency.

[0035] Working principle: When using this handheld spectrum analyzer, the operator can hold the device stably with the handle 11 and operate it through the touch screen 2 and control buttons 4. The RF interface 3 connects to an external antenna or signal source to complete the signal interaction and control of spectrum analysis. When it is necessary to fix the analyzer on a table or desktop, the lever 15 on the fixing block 13 can be turned to disengage the locking lever 18 from the slot 19 of the rotating shaft 5. At the same time, the spring 14 is compressed, and the fixing plate 6 can rotate around the rotating shaft 5. After adjusting to a suitable angle, the lever 15 is released, and the spring 14 rebounds to push the locking lever 18 into the corresponding slot 19 to achieve fixation. When further adjusting the angle of the connecting plate 9, the threaded rod 20 is rotated to disengage it from the slot 21 on the rotating shaft 8. Then, the connecting plate 9 is rotated to adjust the angle between the bracket 10 and the analyzer body 1 to a suitable size. Then, the threaded rod 20 is tightened to lock the angle into the slot 21 of the rotating shaft 8, thereby fixing the analyzer on the ground or desktop.

[0036] Secondly, when not in use, the parts box 23 can be pulled out by the handle 24. The internal partition 25 of the parts box 23 divides the internal space to store small parts such as screws and adapters. The cable box 26 can be pulled out by the handle 27. The cable can be wound around the winding rod 28 and the end can be locked into the cable slot 29 to prevent the cable from becoming loose and tangled. The cable and accessories can be stored in the storage compartment 22. The classified storage of cables and accessories can prevent cables and accessories from being mixed up and lost, thereby improving the portability of use.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
