An eyehook includes a main hook, a gate, and a switch. The main hook includes a first portion, a second portion, and has an opening thereon. The gate is pivotally connected to the second portion, and movable between a first and a second position. When the gate is moved to the second position, the opening is closed. A first main body is clad in a first insulating coat which has a first abutting portion. The switch is pivotally connected to the first portion, and movable between a third and a fourth position. A second main body of the switch is clad in a second insulating coat. The switch abuts against the first abutting portion when moved to the third position to prevent the gate from moving toward the first position. The switch includes a covering portion covering the first abutting portion when the gate is moved to the first position.
