[0002] In the field of electrical testing and repair, a test pen is a fundamental tool for determining whether a circuit is live, and it is widely used in electrical work, household circuit repair, and other scenarios. Currently, many test pens on the market integrate screwdrivers, slotters, and other components to meet multi-functional needs. While this expands the tool's range of applications, the complex assembly makes it difficult to store the various parts properly. Especially after frequent use, parts are prone to being lost or scattered, affecting the tool's integrity and efficiency.

[0003] Meanwhile, the probe, the core detection component of the test pen, is constantly exposed and is easily bent, deformed, or even broken by external impacts or pressure during daily carrying or storage. This not only reduces detection accuracy but also shortens the lifespan of the test pen. In addition, the sharp, exposed probe poses a safety hazard of scratching the user or other tools in confined spaces such as tool bags.

[0004] Therefore, this application provides an electric pen that is easy to store and protect. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figures 1 to 7 As shown, this application provides a conveniently stored and protected electric pen, comprising:

[0030] The test pen 100 includes a storage mechanism 10, an adjustment mechanism 20, a moving mechanism 30, and a test pen mechanism 50. The storage mechanism 10 also includes a main housing 11 with a storage cavity 12 inside. The adjustment mechanism 20 is rotatably connected to the front side of the main housing 11. The moving mechanism 30 includes an insulating screw 31 slidably connected inside the storage cavity 12. The storage mechanism 40 is disposed inside the insulating screw 31 and includes a storage rack 41 fixedly installed inside the insulating screw 31. 1. Limiting grooves 42 are provided on both the left and right inner walls. The electric pen mechanism 50 includes a non-contact inductive electric pen 51 that is slidably connected inside the storage rack 41. A display screen 54 is fixedly installed on the upper wall of one side of the non-contact inductive electric pen 51. Limiting grooves 52 are provided on both the left and right sides of the non-contact inductive electric pen 51. Limiting sliders 53 are movably connected inside the two limiting grooves 52. The side of the limiting sliders 53 away from the limiting grooves 52 is movably connected inside the limiting grooves 42.

[0031] After adopting the above technical solution, by sliding the non-contact inductive pen 51 inside the storage rack 41, when the pen needs to be stored, the non-contact inductive pen 51 can be pulled out. After the non-contact inductive pen 51 is pulled out to its maximum extension range, the non-contact inductive pen 51 is flipped so that its probe faces the storage rack 41 and the non-contact inductive pen 51 is pushed back into the storage rack 41. At this time, the probe is located inside the storage rack 41 and will not be bent, deformed or even broken due to external force collision or squeezing. At the same time, an insulating screw 31 is set inside the main housing 11. The length of the pen can be reduced by retracting the insulating screw 31 into the main housing 11, thereby achieving the effect of easy storage.

[0032] It should be noted that when it is necessary to store the test pen, the internal thread 23 on the inner wall of the rotating ring 22 can be rotated to engage with the external thread on the outer wall of the insulating screw 31, causing the insulating screw 31 to move inward along the inner wall of the main housing 11, thereby retracting the insulating screw 31 into the main housing 11. This changes the overall length of the test pen, thus achieving a convenient storage effect. Alternatively, the non-contact inductive test pen 51 can be pulled outward. After the non-contact inductive test pen 51 is pulled out to its maximum extension range, it can be flipped so that its probe face faces the storage rack 41, and then pushed back into the storage rack 41. At this time, the connecting post... The fixed ball 45 at the end of 44 presses the spring piece 56 and enters between the two spring pieces 56. The position of the non-contact inductive pen 51 is fixed by the spring piece 56 and the fixed ball 45. At the same time, the probe at the end of the non-contact inductive pen 51 is stored through the probe groove 43, which facilitates the storage of the probe. During the use of the pen, the above operation is repeated to pull the probe at the end of the pen out from the storage frame 41 and make it in an outward position. At this time, the insulating screw 31 can be driven to move outward by rotating the rotating ring 22. The length of the pen can be adjusted at will according to different detection targets, so that the pen is suitable for various detection scenarios.

[0033] In an optional embodiment, the adjusting mechanism 20 is fixedly rotatably connected to the front of the main housing 11. An end cap 21 is fixedly installed on one side of the rotating ring 22. The inner wall of the rotating ring 22 is provided with an internal thread 23, and the internal thread 23 is adapted to the external thread on the outer wall of the insulating screw 31. By rotating the rotating ring 22, the internal thread 23 on its inner wall is matched with the external thread on the outer wall of the insulating screw 31, causing the insulating screw 31 to move along the inner wall of the receiving cavity 12, thereby realizing the adjustment of the length of the test pen.

[0034] In one optional embodiment, a limiting block 24 is fixedly installed on the outer wall of the rotating ring 22 near the main housing 11. The outer wall of the front side of the main housing 11 is provided with a stepped limiting groove 14. One end of the limiting block 24 is slidably connected to the inside of the limiting groove 14. By setting the limiting groove 14 and the limiting block 24, the main housing 11 and the rotating ring 22 are connected together on the one hand, and the rotating ring 22 can rotate freely on the front side of the main housing 11 on the other hand.

[0035] In one optional embodiment, limit blocks 2 32 are integrally provided on both the left and right sides of the end of the insulating screw 31, and limit grooves 1 13 are provided on the inner walls of both the left and right sides of the receiving cavity 12. The limit blocks 2 32 are slidably connected to the inside of the limit grooves 1 13. By setting the limit blocks 2 32 and the limit grooves 1 13, the insulating screw 31 will not rotate when affected by the internal thread 23, and the torque it receives is converted into the power for linear movement.

[0036] In one optional embodiment, the non-contact inductive pen 51 has fixing holes 55 on both the top and bottom sides of both ends. Spring pieces 56 are fixedly installed on the top and bottom walls of the fixing holes 55. Multiple connecting posts 44 are fixedly installed on one side of the inside of the storage rack 41. Fixing balls 45 are fixedly installed at the ends of the connecting posts 44. The number of fixing balls 45 and fixing holes 55 are the same. When using the pen or storing the pen, the fixing balls 45 at the ends of the connecting posts 44 squeeze the spring pieces 56 and enter between the two spring pieces 56. The position of the non-contact inductive pen 51 is fixed by the spring pieces 56 and the fixing balls 45.

[0037] In one optional embodiment, a hanging ring 15 is fixedly installed on the rear outer wall of the main housing 11, which allows the stored test pen to be suspended and carried.

[0038] In an optional embodiment, the outer walls of both the main housing 11 and the rotating ring 22 are provided with multiple grooves. By providing the grooves, the friction between the main housing 11 and the outer wall of the rotating ring 22 is increased.

[0039] In an optional embodiment, a probe slot 43 adapted to the probe at the end of the non-contact inductive pen 51 is provided at the center of the right side of the storage rack 41. When the pen enters the storage rack 41, the probe slot 43 provides storage space for the probe at the end of the pen.
