Claims

[Claims for Utility Model Registration] (1) A pair of parallel leg plates are symmetrically arranged, and a rod connecting the leg plates is provided horizontally and in the left-right direction on the upper part of the leg plates, and a rod is provided at the center of the rod. A shaft rod having a handle for rotation operation at the top is screwed together in the vertical direction, and an elevating rod that moves up and down along the inner surface of the leg plates is arranged horizontally at the lower end of the shaft rod located between the leg plates. In the connector extraction device, the elevating rod is provided with a pair of right and left claws that engage with recesses formed at the left and right ends of the connector, respectively, in which the pair of parallel leg plates are arranged along the longitudinal direction of the rod. A connector extraction device in which each of the claws is movable along the longitudinal direction of the lifting rod. (2) The connector extraction device according to claim 1, wherein the leg plate attachment hole formed in the longitudinal side surface of the rod is formed in a penetrating shape and continuous along the longitudinal direction of the rod. (3) Claim 1, wherein the claw attachment hole formed on the longitudinal side surface of the lifting rod is formed in a penetrating shape and continuous along the longitudinal direction of the lifting rod.
Or the connector extraction device described in 2. (4) Claim 1 or claim 2, wherein the claw part is formed so that its upper part can be freely inserted into the lifting rod, and a screw is provided on the side surface of the upper part for fixing the claw part main body to the lifting rod. 2. The connector extraction device according to 2. (5) Claim 1, wherein the claws are each arranged in a contracted state at all times on the center side of the lifting rod by a spring.
Or the connector extraction device described in 2.
