[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1-5 As shown, this utility model provides a technical solution for a portable electric cockroach killer, including a handheld tube 1. A first extension rod 2 is slidably connected inside the handheld tube 1, and a second extension rod 3 is slidably connected inside the first extension rod 2. A battery 4 is slidably connected to one end of the handheld tube 1, and a sealing plate 5 is threadedly connected to one end of the handheld tube 1. A connecting wire 6 is connected to the handheld tube 1 through a controller, and an electric shock head 7 is fixedly connected to one end of the connecting wire 6. The electric shock head 7 is fixedly connected to one end of the second extension rod 3, and the output end of the battery 4 is electrically connected to the input end of the controller.

[0023] Both the first extension rod 2 and the second extension rod 3 have threaded grooves at their ends. The end of the hand-held tube 1 has a corresponding groove to the end of the first extension rod 2. The threaded grooves are connected to the corresponding grooves by threads, which facilitates the fixing of the first extension rod 2 and the second extension rod 3 after they are moved, and enables the cockroach-killing stick to be unfolded.

[0024] Personnel can move the first extension rod 2 and the second extension rod 3 to a suitable position, and then rotate the first extension rod 2 and the second extension rod 3 to fix the first extension rod 2 and the second extension rod 3 to the handheld tube 1 and the first extension rod 2 through threaded connection. This allows for the extension of the cockroach-killing stick. When not in use, the cockroach-killing stick can be shortened for easy carrying and improved portability. Personnel can then use the cockroach-killing stick by turning on the electric shock head 7.

[0025] A fixed shaft 8 is fixedly installed at one end of the second extension rod 3. A winding drum 9 is rotatably embedded and connected to the outside of the fixed shaft 8. Tension springs 10 are welded to both ends of the winding drum 9. The tension springs 10 are fixedly connected to the inside of the second extension rod 3.

[0026] When personnel use the cockroach-killing stick, as the first extension rod 2 and the second extension rod 3 are extended, the winding drum 9 retracts and extends, winding up the connecting line 6. When the first extension rod 2 and the second extension rod 3 are retracted, the tension spring 10 returns to its original position, causing the winding drum 9 to rotate and wind up the connecting line 6. This ensures that the connecting line 6 is wrapped around the outside of the winding drum 9, facilitating the unfolding of the cockroach-killing stick and preventing the connecting line 6 from getting tangled inside the stick during extension and retraction, thus ensuring the stick's usability.

[0027] One end of the handheld tube 1 is fitted with a spring telescopic column 11 by screws. A rotating block 12 is rotatably connected to the top of the spring telescopic column 11. One end of the rotating block 12 is fitted with a connecting rod 13 by screws. One end of the connecting rod 13 is fitted with a protective tube 14 by screws.

[0028] The rotating block 12 has a T-shaped longitudinal section, and the protective cylinder 14 is located in the middle of the handheld cylinder 1 to prevent the rotating block 12 from falling off. The protective cylinder 14 can also protect the electric shock head 7.

[0029] After storing the cockroach-killing stick, personnel can rotate the protective cylinder 14 to extend the spring telescopic column 11, move the protective cylinder 14 to the end of the electric shock head 7, and then release the protective cylinder 14 to compress the spring telescopic column 11, so that the protective cylinder 14 is outside the electric shock head 7. This facilitates the protection of the electric shock head 7 when the cockroach-killing stick is not in use, avoids the electric shock head 7 from colliding with external objects and causing damage to the electric shock head 7, and ensures the safety of the cockroach-killing stick when it is not in use.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
