[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1: As Figures 1-6 shown, the present utility model provides a technical solution: an electric power detection pen, which includes a grip 1. One end of the grip 1 is fixedly installed with a detection block 2. A display screen 3 is fixedly installed on the surface of the detection block 2. One end of the detection block 2 is fixedly installed with a baffle 4. Anti-slip strips 5 are fixedly installed on both sides of the grip 1. A groove 6 is opened inside the detection block 2. A torsion block 7 is rotatably connected to one side of the grip 1. A worm 8 is fixedly installed on the surface of the torsion block 7. A sleeve 10 is rotatably connected inside the grip 1. A worm gear 9 is fixedly installed at one end of the sleeve 10. A lead screw 11 is threadedly connected inside the sleeve 10. A limit block 12 is fixedly installed at one end of the lead screw 11. A detection head 13 is slidably connected inside the limit block 12. A placement groove A14 is opened inside the limit block 12. A through groove 15 is opened at the bottom of the placement groove A14. A card slot 16 is opened inside the placement groove. A sliding groove A17 is opened at the top end of the placement groove A14. A spring 18 is slidably connected inside the lead screw 11. A top block 19 is slidably connected inside the placement groove A14. A convex block 20 is fixedly installed on the surface of the detection head 13. The detection head 13 is electrically connected to the display screen 3. The worm 8 is meshed with the worm gear 9. The limit block 12 is slidably connected with the groove 6. The worm 8 is rotatably connected with the grip 1. One end of the spring 18 is connected to the surface of the groove 6, and the other end is connected to the bottom surface of the top block 19. The convex block 20 is slidably connected with the sliding groove A17, the card slot 16 and the through groove 15.

[0026] In this embodiment, the worm 8 and the worm wheel 9 are driven to rotate synchronously by rotating the torsion block 7. The worm wheel 9 will drive the sleeve 10 to rotate when rotating, and the sleeve 10 will drive the screw rod 11 to extend from the sleeve 10, thereby driving the limit block 12 to slide outward in the groove 6. At this time, the screw rod 11 will drive the detection head 13 to extend from the detection head 13, avoiding the problem of insufficient length of the detection head 13 during the detection work. When replacing the detection head 13, it is only necessary to press the detection head 13 into the screw rod 11, thereby driving the protrusion 20 to descend into the through groove 15, and then rotate the detection head 13 so that the detection head 13 drives the protrusion 20 to slide in the through groove 15. After the block 20 slides to the slide groove A17, the detection head 13 can be pulled out from the screw rod 11, and then a detection head 13 of a different type can be inserted into the screw rod 11. At this time, the detection head 13 will drive the protrusion 20 to slide inside the slide groove A17 and slide to the top block 19. The top block 19 is pressed to move the protrusion 20 into the through groove 15. At this time, the detection head 13 is rotated to rotate the protrusion 20 into the slot 16. At this time, the spring 18 under the top block 19 rebounds and drives the top block 19 to fix the detection head 13 in the slot 16. This device effectively solves the problem that the electric tester cannot accurately and effectively detect when working in a special environment due to insufficient length and the single shape of the detection head 13.

[0027] Example 2: Figures 1-6 As shown, a placement groove B21 is provided on one side of the detection block 2, a sleeve rod 23 is rotatably connected inside the detection block 2, a torsion spring 24 is sleeved on the surface of the sleeve rod 23, a cover plate 22 is fixedly installed on one end of the sleeve rod 23, a slide groove B29 is provided on the surface of the detection block 2, an insertion rod 25 is slidably connected inside the slide groove B29, a shift block 26 is fixedly installed on the surface of the insertion rod 25, a clamping block 27 is fixedly installed inside the placement groove B21, a retaining ring 28 is fixedly installed on the surface of the clamping block 27, one end of the torsion spring 24 is connected to the side of the cover plate 22, and the other end is connected to the inner surface of the detection block 2, the shift block 26 is slidably connected to the slide groove B29, and the insertion rod 25 is slidably connected to the cover plate 22.

[0028] In this embodiment, by moving the shift block 26, the shift block 26 slides in the slide groove B29. At this time, the shift block 26 will drive the insertion rod 25 to slide inside the detection block 2, and the insertion rod 25 will also slide inside the cover plate 22. After the insertion rod 25 completely leaves the cover plate 22, the cover plate 22 will rotate due to the torsion force of the torsion spring 24 until the placement groove B21 is opened. The removed detection head 13 can be fixed in the retaining ring 28 on the clamping block 27, and the detection head 13 suitable for the current working environment can be taken out. After the replacement is completed, the cover plate 22 is rotated again. After the cover plate 22 closes the placement groove B21, the shift block 26 is moved again. After the shift block 26 drives the insertion rod 25 to be inserted into the interior of the cover plate 22, the cover plate 22 can be fixed. This device effectively avoids the problem of inconvenience in carrying multiple detection heads 13 for storage.

[0029] The working principle of this embodiment is as follows: when in use, first rotate the torsion block 7 to drive the worm 8 and the worm wheel 9 to rotate synchronously, so that the sleeve 10 and the screw rod 11 make a threaded movement forward. At this time, the screw rod 11 will drive the detection head 13 to extend out of the limit block 12. When working in a special environment, the detection head 13 can be pressed to drive the protrusion 20 to drop out of the slot 16, and then the detection head 13 can be rotated to the slide groove A17 to complete the removal of the detection head 13. After the removal is completed, the detection block 26 on the surface of the detection block 2 can be moved. The movable plug rod 25 slides in the cover plate 22. After the plug rod 25 completely leaves the cover plate 22, the cover plate 22 automatically opens due to the reaction force of the torsion spring 24. At this time, the disassembled detection head 13 can be fixed in the retaining ring 28 on the clamping block 27, and the detection head 13 suitable for the current working environment can be taken out. After the replacement is completed, the cover plate 22 is pressed to its original position, and the block 26 is moved to drive the plug rod 25 to slide in the slide groove B29 to the inside of the cover plate 22, and the cover plate 22 can be closed. At this time, the replacement of the detection head 13 is completed.
