Description

Technical Field

[0001] The utility model relates to the technical field of direct-plug-in electrometers, in particular to a direct-plug-in electrometer. Background Art

[0002] A plug-in tester is a device used to detect whether there is electricity in an electrical device or circuit. It usually consists of a metal probe and an indicator. When the probe touches a charged object, the indicator lights up or makes a sound, indicating that the object is charged.

[0003] In order to cope with different working conditions, the current plug-in electrometer needs to use different types of test probes when testing different equipment. The current plug-in electrometer test probes are usually not replaceable, or are replaced by threaded rotation, which is troublesome to replace. Some equipment, such as a test pencil blade and a test pencil disclosed in the authorization announcement No. CN219512318U, record the following: "The blade fixing component is provided with the plug-in hole, and the blade fixing component is configured to have a non-rotating interference fit with the test pencil blade, and the matching force of the non-rotating interference fit is adjustable." Although the test probe of this device is relatively easy to replace, the test probe is installed on the electrometer by interference fit. After long-term use and multiple replacement of the blade, the fixing component will be worn, which can easily lead to unstable installation of the test probe. The test probe falls during operation, resulting in inability to work. For this reason, a plug-in electrometer is proposed. Utility Model Content

[0029] Working principle: when you want to replace the electrical test probe 5, first turn the pen tip 2 to the left. The pen tip 2 can only turn ninety degrees to the left under the restriction of the limit column 4 and the limit arc groove 3. The pen tip 2 drives the limit sleeve 8 to rotate through the limit cylinder 14 and the rotating slide groove 15. The limit sleeve 8 rotates at the bottom end of the connecting block 16. At this time, the arc-shaped block 10 on the back is squeezed and moves backward, breaking away from the contact with the arc-shaped groove 13, and then moves outward under the action of the limit spring 11. The arc-shaped block 10 drives the fixed block 12 to move outward, and the fixed block 12 breaks away from the fixed groove 7. At the same time, the original arc-shaped block 10 on the right is connected to the arc-shaped groove 13. At this time, the electrical test probe 5 can be easily removed for replacement, and then the new electrical test probe 5 is inserted, and the replacement can be completed by turning the pen tip 2 to the right. When the length of the electrical test probe 5 is to be changed, the push block 18 is pushed downward, and the push block 18 drives the limit box 17 to slide downward in the sliding vertical slot 19. At this time, the limit slot 24 squeezes the limit spring piece 23, and the limit spring piece 23 is squeezed, and the upper and lower ends are opened, driving the sliding cylinder 22 to slide up and down inside the rounded slide slot 21, so that the limit spring piece 23 is retracted into the rectangular slot 20. When it is not squeezed by the limit slot 24, the limit spring piece 23 pops out, and the limit box 17 drives the connecting block 16 to move downward, and the connecting block 16 drives the limit sleeve 8 to move downward, and the limit sleeve 8 pushes the electrical test probe 5 to slide downward, and the limit cylinder 14 slides downward in the rotating slide slot 15, thereby pushing the electrical test probe 5 out.
