Abstract

A handheld device having a lamp for testing and clipping a blade fuse includes a handle having two probes extended therefrom, a clamp formed on one end of the handle, and an indicator for indicating the condition of the fuse. One of the probe is movably disposed on the handle, thereby allowing the adjustment of separation between two probes. Finally, one side of the handle includes a first lamp, which is disposed parallel to the probe and is electrically connected to the circuit board for illuminating the fuse to be tested. The other side of the handle includes a second lamp, which is disposed parallel to the clamp and is electrically connected to the circuit board for illuminating the fuse to be pulled out.

Claims

1. A handheld device for testing a blade fuse, comprising a handle having a clamp formed on one end thereof, the handle comprising a circuit board disposed in the handle, two probes electrically connected to the circuit board and extended out from the handle, and an indication unit exposed outside of the handle for indicating whether the tested fuse is damaged;

where

one side of the handle comprises a first lamp, which is disposed parallel to the probe and is electrically connected to the circuit board for illuminating the fuse to be tested;

one side of the handle comprises a second lamp, which is disposed parallel to the clamp and is electrically connected to the circuit board for illuminating the fuse to be pulled out.

2. The device as recited in claim 1, wherein the switch is an electronic switch.

3. The device as recited in claim 1, wherein the switch is a mechanical switch.

4. The device as recited in claim 1, wherein at least one of the probes is adjustably disposed on the handle for adjusting the separation between the two probes.

5. The device as recited in claim 4, wherein at least a linear sliding groove is formed on the front end of the handle, the adjustable probe being extended from the sliding groove and horizontally movable in the sliding groove.

6. The device as recited in claim 1, wherein the lamp comprises a light emitting diode.

7. The device as recited in claim 1, wherein the first lamp is substantially parallel to the probe.

8. The device as recited in claim 1, wherein the second lamp is substantially parallel to the clamp.
