Equipped with light bulb, the side of general-purpose watchcase is equipped with switch, and the switch is connect with light bulb and battery respectively by conducting wire, described defeated
Enter and is equipped with shield above hole.
As a kind of optimal technical scheme of the utility model, general-purpose watchcase front lower end has one to the recessed of lower recess
Slot, the input hole are located in groove, and the upper and lower edge of the groove is respectively fixed with " L " type fixing piece, and two solid
Determine the opening of part relatively and form a slot, the width of the shield adapts to the width of slot, by shield along one end of slot
Shield can be fixed on above groove by push-in.
As a kind of optimal technical scheme of the utility model, described shield one end is connected with a baffle, the baffle
Width is more than the width of shield.
As a kind of optimal technical scheme of the utility model, handle is fixedly connected on the side of the general-purpose watchcase.
As a kind of optimal technical scheme of the utility model, the handle include grab and be located at grab a both ends and to
Ear is grabbed in the same side bending, and described to grab handle and be integrally formed with ear is grabbed, the ear of grabbing is fixedly connected on the side of general-purpose watchcase,
The side of hand and general-purpose watchcase surrounds a through-hole.
The utility model has the beneficial effects that：
The utility model is simple in structure, easy to use, makes digital multimeter have the illumination of torch by the way that light bulb is arranged
Function, while only needing to hold handle and can easily take digital multimeter, avoid touch it is aobvious on general-purpose watchcase
Display screen or mode button, and being located at the shield above input hole can enter to avoid dust debris, avoid input hole and test pencil
Poor contact causes prohibited data detection true.

Specific implementation mode
The utility model row is further described presently in connection with attached drawing.
As shown in Figure 1 and Figure 2, a kind of digital multimeter illuminated, including multimeter ontology and two test pencils, described ten thousand
Include general-purpose watchcase 1 with table ontology, 1 front of the general-purpose watchcase is equipped with display screen 2, mode button 3, operation successively from top to bottom
Knob 4 and input hole 5,1 back side of general-purpose watchcase are equipped with the battery case for installing battery, and 1 top of the general-purpose watchcase is fixed
There are a light bulb 6, light bulb 6 to be nested in 1 top of general-purpose watchcase, light bulb is installed in light bulb 6, the side of general-purpose watchcase 1, which is equipped with, opens
7 are closed, the switch 7 is connect with light bulb and battery respectively by conducting wire, when the light of the inners such as the switch cabinet to be overhauled
When weaker, 7 can be turned on the switch, light bulb shines, and digital multimeter can treat as torch and use.
