A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped. The crimping tool has a simple structure and good crimping performance, so that the workpiece is uniformly stressed and burrs on the workpiece can be reduced.

A device for removing wall plugs from the walls. The device has 2 main elements, a double-headed screw and a hub, which together are manually operated to remove the wall plugs from the walls easily and without damage to the surfaces. The set of the screw for removing wall plugs and the hub is called the device for removing wall plugs. The device for removing wall plugs is made up of 2 elements: a screw for removing wall plugs and an extractor hub. These 2 elements are coupled so that the device for removing wall plugs works properly. The screw for removing wall plugs is a longitudinal element with double head. It features a screw rope, a manual turning head and an electric turning head.

A rattle insertion device and method for inserting a rattle into an elastomeric fishing lure that includes having a push rod member with an insertion rod portion, a needle member with a second needle end operably configured to puncture an elastomeric lure and that defines a needle channel with a channel diameter greater than a rod diameter and a needle opening disposed along the needle length. Additionally, the device and method include having a rattle member with a rigid rattle member, sized to be inserted within the needle channel, and that defines a rattle cavity encapsulating one or more rigid noise particle therein that are operably configured to be freely mobile therein. The push rod member is operably configured to translate within the needle channel along a rod translation path to transport the rattle member through the needle channel and out through the needle opening.

A tool for replacing an escalator drive shaft comprises a first tool and a second tool. One side of the first tool is adapted to be assembled on an original shaft adapter, and the other side of the first tool is adapted to be assembled on a new shaft adapter. The second tool is adapted to be assembled on the first tool. A central axis of the first tool coincides with a central axis of the original shaft adapter, a central axis of the second tool coincides with the central axis of the first tool, and the central axis of the first tool coincides with a central axis of the new shaft adapter. A positioning reference of the original drive shaft is accurately transferred to the new drive shaft by the first and second tools, so that the new drive shaft may be accurately assembled to the position of the original drive shaft with respect to the truss after replacement.

A tool adapted for use with a diffuser cartridge and a fluid container, wherein the tool is adapted to facilitate insertion and removal of the diffuser cartridge to and from the fluid container. The diffuser cartridge contains mineral agent beads or other materials which can enhance the quality of fluid contained within the container.
