Abstract:
A wire connection box and an inserting rod assembly comprising: a retaining seat, a rapidly-connecting Joint fixed to a front end of the retaining seat, a wire connection box, and the inserting rod inserted in the retaining seat, a front end of the inserting rod with respect to the retaining seat being firmly secured with said rapidly-connecting Joint; and the retaining seat firmly secured to an outer side of the wire connection box, wherein one end of the retaining seat protrudes from said outer side of the wire connection box to form a protruded section; and a distal end of the protruded section comprising a shaped engaging portion; an intermediate portion of said retaining seat having a groove for positioning steel balls; the rapidly-connecting joint comprising a connecting tube having a smaller annular surface and a stepped surface, a spring, and an actuating toggle, said connecting tube installed to said shaped engaging portion of the protruded section, said spring enclosing said smaller annular surface of the connecting tube, and said actuating toggle fixed at an outer side of the connecting tube by a C ring to resist against said spring, the smaller annular surface of the connecting tube being tapered from a front end of the connecting tube to said stepped surface; said front end of the connecting tube having an embedded trench for receiving the C ring; said smaller annular surface of said connecting tube having a receiving hole for receiving said steel balls; a middle section of the connecting tube being matched to the shaped engaging portion of the protruded section and having a polygonal engaged hole for securing the rapidly-connecting joint; the actuating toggle comprising an inner annular portion which has a resisting flange at a position with respect to the steel balls of the connecting tube, the resisting flange and the inner annular portion of the actuating toggle being formed with stepped surfaces; one side of the spring resists against the stepped surface of the connecting tube and another end of the spring resists against the resisting flange of the actuating toggle, whereby the inserting rod can be pulled out from the retaining seat in advance for packaging, transferring and storage with a smaller volume.
