<p>The present invention relates to a pusher device and, more specifically, to a pusher device which pressurizes a tested device of which an electric inspection is required towards an inspection device. The pusher device comprises; an upper cover wherein a center hole is formed on the center vertically; a pusher unit which moves in the upper and lower directions while the lower side thereof can be in contact to the upper side of the tested device; and a position moving unit which moves the pusher unit in the upper and lower directions. The pusher unit comprises a main pusher having an insertion hole of which at least a part is inserted into the center hole of the upper cover and moves in the upper and lower directions along the longitudinal direction of the center hole. The pusher unit includes a sub pusher of which at least a part is inserted into the insertion hole formed on the main pusher. The sub pusher moves in the upper and lower directions along a penetration direction of the insertion hole. The position moving unit includes a descending member. The descending member includes a first position moving unit including; a handle for pressurization which is arranged on the upper side of the upper cover and is rotated in respect with a rotary shaft which is parallel to the longitudinal direction of the center hole; and a first conversion unit capable of converting a rotary motion into a straight line motion of the handle for pressurization and taking down the pusher unit. The descending member includes a second position moving unit of which at least a part is inserted into the insertion hole formed on the main pusher. The second position moving unit is arranged on the upper side of the sub pusher and takes down the sub pusher.</p> |
