[0010] Beneficial Effects

[0011] The utility model provides an electrical circuit test box, which has the following beneficial effects:

[0012] (1) The electrical circuit test box places the wire to be tested through the groove into the position of the corresponding constraint groove above the contact guide column, and then pulls the movable column downward through the spring. The movable column drives the extrusion block to insert the wire placed on the contact guide column into the inside of the constraint groove to further fix the wire. It is easy to use and convenient for quick measurement.

[0013] (2) The electrical circuit test box guides the wires through two guide plates, thereby facilitating the insertion of the wires and enhancing the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
