DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 2-5 As shown, in this embodiment, a shift block 604 is installed on the upper surface of the slider 609, a test button 603 is installed on the side of the pen barrel 601 away from the sliding groove 607, the test button 603 is electrically connected to the test pen tip 606, the test pen tip 606 is installed inside the pen barrel 601, and a movable perforation is provided on the outer side of the test pen tip 606 located inside the insulating pen cover 605, a display screen 2 is provided on the upper surface of the detector 1, and a voltage regulating knob 3 is installed on the upper surface of the detector 1 below the display screen 2, and the voltage regulating knob 3 and the display screen 2 are both electrically connected to the detector 1.

After holding the test pen 6, the test button 603 on the outside of the pen holder 601 is pressed to open the electrical path between the test pen 6 and the detector 1. When testing, the slider 609 is driven to slide in the sliding groove 607 by the hand to compress the spring 608 as a whole, so as to realize that the slider 609 drives the insulating pen cover 605 as a whole.
