1. An oil filling device configured to be applied to an oil pot including an open end portion, including:
a main body, configured to cover the open end portion, including at least one first sliding portion and a channel, the channel being in communication with the oil pot;
a control member, freely rotatably disposed around a portion of the main body and rotatable about an axial direction;
two clamping members, at least one of the two clamping members including a second sliding portion slidably mounted to the at least one first sliding portion;
at least one guiding unit, each of the at least one guiding unit including a guiding groove which extends in a direction oblique to a radial direction of the control member, and an assembly portion; and
at least one positioning member, each of the at least one positioning member being connected to one said assembly portion and slidably disposed within one said guiding groove, wherein rotation of the control member operates to control at least one of the two clamping members to move relative to the main body so that the two clamping members relatively approach to or distance away from each other;
wherein the control member is in a non-threaded engagement with the main body, and rotation of the control member causes no axial movement of the control member relative to the main body;
wherein the at least one first sliding portion projects and extends radially on a side of the main body facing the control member, the second sliding portion is a recess, and the at least one first sliding portion projects to be within the recess so that the two clamping members are non-rotatable relative to the at least one first sliding portion and are only radially slidable along the at least one first sliding portion.
