The connection plug 10 is pulled out. For this reason, the connector pulling tool 30 having the above-described configuration allows the connection plug 10 to be connected from the U link 20 in a state where the U link 20 is connected to the target device without causing the U link 20 to be accidentally dropped from the target device. Can be pulled out.

  In addition, since the connector pulling tool 30 according to the present embodiment includes the cover 30c that covers the plug body 10a of the connection plug 10, the operator holds the cover 30c that covers the plug body 10a of the connection plug 10 with one hand. On the other hand, when the pressing portion 30a2 of the pressing body 30a is pressed in the extending direction of the wedge portion 30a1 with the thumb of the same hand and the wedge portion 30a1 is pushed between the opposing wall portion 30b of the cover 30c and the plug body 10a, the connection plug 10 Moves freely within the cover 30c and is separated from the U link 20 side. Therefore, by providing the cover 30c that covers the plug body 10a, the connection plug 10 can be easily moved and the workability is excellent.

  In this case, the wedge portion 30a1 is formed such that the surface of the U link 20 on the connector main body 20c side is a plane along the opposing wall portion 30b, and the surface of the connection plug 10 on the plug main body 10a side is the plane. Since the end portion is formed as an inclined surface separated from the plane, the operator holds the cover 30c covering the plug body 10a of the connection plug 10 with one hand and presses the pusher 30a with the thumb of the same hand. When the portion 30a2 is pressed in the extending direction of the wedge portion 30a1 and the wedge portion 30a1 is pushed between the connector body 20c and the plug body 10a, the distance between the U link 20 and the connection plug 10 increases as the wedge portion 30a1 is pushed. It becomes easier to spread, and it becomes more excellent in workability.

  The connector pulling tool 30 of the present invention is not limited to the above-described embodiment, and various modifications are of course made without departing from the scope of the present invention.

  In the above embodiment, the pressing body 30a is provided with the pressing portion 30a2 provided at the base end of the wedge portion 30a1, but the present invention is not limited thereto, and the pressing body 30a is configured only by the wedge portion 30a1. Also good.
