Abstract: A system and method of instant-messaging bot that provide a chatbot and human agents working in accord in communicating with users over a public instant-messaging (IM) platform includes a chatbot application and an IM platform, both built for an enterprise. The enterprise IM platform is connected to the chatbot application and separately connected to one or more public IM platforms via the Internet. The chatbot application contains software for receiving, processing, analyzing and responding to human-generated messages in a human-like manner. The enterprise IM platform contains software for managing traffic of IM messages exchanged among the chatbot, one or more human agents connected to the enterprise IM platform, and any user connected to one of the public IM platforms.

Abstract: A drawing device of the present invention includes a first driving element, a bolt, a plurality of second driving elements, and a plurality of clipping rods. The first driving element drives the second driving elements to rotate simultaneously, so that the clipping rods are able to be rotated and operated. Also, a hook portion of each clipping rod is able to hook to a bottom of objects to be drawn out, and the bolt is disposed on a threaded hole of the first driving element and abuts against the objects to be drawn out. At the same time, the clipping rods are moved outward.

Abstract: According to the present invention, the oil filter replacement device has a number of pins for clamping an oil filter, and the pins are extended eccentrically from corresponding secondary gear members. The secondary gear members are engaged to spin simultaneously by a main gear member. As such, the pins could be adjusted to fit on oil filters of various sizes. Additionally, each pin is rotatable and has at least a flat face. As the pins rolls along the circumference of the oil filter, their flat faces are turned to interface the flat faces around the oil filter. As such, the oil filter is tightly and reliably clamped by the oil filter replacement device, thereby preventing the problem of uneven exertion of force and deforming the oil filter.

Abstract: An oil filter canister adapter of the present invention mainly includes a base, a rotatable plate, three rotatable members, and three holders. The rotatable plate and the rotatable members are respectively disposed on the base. The rotatable members contact with the rotatable plate respectively, so that the rotatable plate can rotate and drive the rotatable members to rotate. The holders are detachably disposed on the rotatable members respectively. Distances between any two adjacent holders are consistent in value. The distances between the holders are adjustable when the rotatable members rotate. Therefore, the holders can be detached from the rotatable members. Volume of the adapter is minimized for storage. As such, cost of transportation or storage of the adapter can be well controlled.
