The utility model discloses a device for fetching the w pin of the antifouling disc-shaped suspension-type ceramic insulator, and the device comprises a pin-fetching apparatus in an integrated structure. The front end of the pin-fetching apparatus is a pin-fetching apparatus head, and the rear end of the pin-fetching apparatus is a hand-held part. A connecting part is disposed between the pin-fetching apparatus head and the hand-held part, wherein the pin-fetching apparatus head is recessed. Only if the device is pushed inwards to enable the w pin to be pushed outwards, the w pin can be pushed out from a socket. Because the device is simple in shape and small and exquisite, the device is especially suitable for a narrow spatial environment between porcelain petticoats. Moreover, the force-applying direction is changed from a direction towards a user or towards the right to an inward direction, so a worker can apply a force more easily. In addition, the operation is simple, and the control intensity and direction can be controlled easily. The damage to porcelain petticoats is not liable to be caused by unstably forces. The beneficial effects of the utility model are that the device is simple and convenient, saves labor, is quick, is especially suitable for the narrow spatial environment between porcelain petticoats, is not liable to damage the porcelain petticoats, and can save the time of live-line operation.
