[0028] Working principle: When using the anti-drop handheld hole copper thickness gauge, first, pull the plug 3 and insert it into the socket 2. At this time, the fixed block A6 will be driven to dock with the fixed block B7, and the fixed block A6 will squeeze the card block 11. The card block 11 will pull the connecting block 10 and then drive the connecting rod 9 to slide outward along the sliding groove 8. When the connecting rod 9 slides, it will squeeze the spring 13. When the fixed block A6 and the fixed block B7 are fitted together, the card block 11 will be driven to dock with the card slot 12. At this time, the squeezed spring 13 will push the connecting rod 9 to reset through its own tension, and the connecting rod 9 will push the card block 11 to snap into the inside of the card slot 12 for locking and fixing. In this way, the fixed block A6 and the fixed block B7 can be fixedly connected together, thereby preventing the socket 2 and the plug 3 from loosening and falling.

At this time, the extension block 19 and the protrusion 20 will be deformed. When the extension block 19 and the protrusion 20 pass through the interior of the limit frame 21, the deformed extension block 19 and the protrusion 20 will automatically reset and rebound. The protrusion 20 after rebound will be engaged with the limit frame 21, so that the protective cover 15 can be fixed. At this time, the protective cover 15 will drive the sealing strip 16 to embed into the sealing groove 17, and the sealing strip 16 can be used for sealing. Among them, the protective cover 15 can prevent the button on the test instrument 1 from being accidentally touched during non-operation. This is the working principle of the anti-drop handheld hole copper thickness gauge.
