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.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a portable automotive electronics testing device, comprising a housing 1, which forms the foundation of the entire device and protects its internal structure. A protective shell 2 is fixedly connected to the inner wall of the housing 1, protecting the internal recovery components. A movable plate 3 is slidably connected to the top of the protective shell 2. Connecting plates 4 are rotatably connected to both sides of the movable plate 3. Pawls 5 are fixedly connected to the right sides of the two connecting plates 4. The movable plate 3 receives external force, thereby moving the connecting plates 4 and thus moving the pawls 5, thereby stabilizing the device. A rotating rod 6 is rotatably connected to the inner wall of the protective shell 2. A spring-loaded spring 7 is fixedly connected to the outside of the rotating rod 6, and a ratchet 9 is fixedly connected to the outside of the rotating rod 6. The rotating rod 6 is externally fixedly connected to the housing 8. The rotating rod 6 receives the rotational force from the spring 7 and the ratchet 9, thus rotating and also driving the housing 8 to rotate. The spring 7 receives the rotational force from the rotating rod 6, thus compressing. The ratchet 9 is limited by the pawl 5 and disengages from the control of the pawl 5, rotating under the action of the spring 7. The housing 8 facilitates the retraction of the transmission line 12. The bottom of the moving plate 3 is fixedly connected to the spring 10. The right side of the housing 1 is slidably connected to the transmission line 12. The spring 10 receives the moving force of the moving plate 3, thus compressing the elastic force. The transmission line 12 transmits electricity to the probe. The right side of the transmission line 12 is fixedly connected to a disassembly assembly for disassembling the probe head.

[0033] Reference Figure 2 and Figure 4The disassembly assembly includes a movable block 14, the left side of which is fixedly connected to the right side of the transmission line 12. The movable block 14 is controlled by the probe line to move. A protective cover 13 is slidably connected to the outside of the movable block 14. The protective cover 13 protects the internal disassembly assembly and stabilizes it. A movable plate 3 20 is slidably connected to the bottom of the protective cover 13. A movable plate 2 17 is fixedly connected to the top of the movable plate 3 20. Two rotating plates 18 are rotatably connected to the left side of the movable plate 2 17. A limit plate 19 is fixedly connected to the adjacent side of the two rotating plates 18. The movable plate 3 20 receives external force, thereby driving the movable plate 2 17 to move. The movable plate 2 17 receives the pushing force of the movable plate 3 20, thereby driving the rotating plates 18 to move, so that the two rotating plates 18 rotate, thereby driving the limit plate 19 to rotate.

[0034] Reference Figures 1 to 3 The ratchet 9 is externally engaged with the pawl 5, and the ratchet 9 and pawl 5 mesh with each other, thus limiting the ratchet 9. A horizontal plate 24 is fixedly connected to the bottom of the spring 10. The left side of the horizontal plate 24 is fixedly connected to the left inner wall of the protective shell 2. The horizontal plate 24 is where the spring stores its elastic force to stabilize it. A force-applying plate 23 is fixedly connected to the top of the moving plate 3. The outside of the force-applying plate 23 is slidably connected to the top of the protective shell 2. The force-applying plate 23 receives the pushing force from the operator, thereby driving the moving plate 3 to move. A connecting rod 11 is fixedly connected to the adjacent side of each of the two pawls 5. The connecting rod 11 connects the two pawls. 5. To synchronize their movement, a control panel 25 is fixedly connected to the inner wall of the outer casing 1. The control panel 25 is the central part of the entire device. A fixing block 22 is fixedly connected to the right side of the outer casing 1. A limiting block 21 is fixedly connected to the outside of the transmission line 12. The outside of the limiting block 21 is connected to the inside of the fixing block 22. The fixing block 22 limits the limiting block 21, allowing it to be locked inside the fixing block 22. A spring 16 is fixedly connected to the rear side of the moving plate 17. The right side of the spring 16 is fixedly connected to the right inner wall of the protective cover 13. The spring 16 receives the moving force of the moving plate 17, thus extending and storing Tang Rui. A limiting block 15 is fixedly connected to the right side of the moving block 14. The left side of the limiting block 15 contacts the rear side of the two limiting plates 19, limiting the limiting block 15 and thus stabilizing it.

[0035] Working principle: The operator presses the force plate 23, which moves the moving plate 3, compresses the spring 10, and moves the connecting plate 4, causing the pawl 5 to rotate. This disengages the pawl from the ratchet 9, releasing the spring 7 and causing the rotating rod 6 to rotate. The rotating rod 6 then moves the winding shell 8, retracting the transmission line 12. Finally, the limiting block 21 is locked onto the fixing block 22. This process allows for the storage of the test lines of the electronic testing device, making it easy to carry and organize, preventing test lines from getting tangled and damaged, saving space, and improving usability and device neatness.

[0036] The operator holds the bottom movable plate 3 20 and moves it, which in turn moves the movable plate 2 17, causing the rotating plate 18 to rotate, which in turn rotates the limiting plate 19, thus disengaging the limiting plate 19 from the control of the limiting block 1 15. This causes the movable block 14 to move, and the transmission line 12 to disengage from the control of the probe, thereby realizing the disassembly of the test probe of the electronic testing device. In addition, it is convenient and flexible to adapt to different testing scenarios, so that diverse testing needs can be met by changing the probe.

[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.
