    Abstract: The present invention relates to a snap ring pliers. As to the entire structure of the present invention, a lock member is simply turned to control gripping members to hold or release deformation of a snap ring. The lock member is turned for a stop of a limit member to hold against the upper surface of an elastic plate to block a hook portion from moving upward, so that the elastic plate can be made with a thinner plate. The hook portion is flexibly held by teeth of a ratchet rail. A lower protrusion of the elastic plate is held by an upper protrusion of the lock member with less resistance. This enhances the lock member to be turned in a labor-saving or flexible way.

A jig is then placed over the shaft and the springs and has at least one axially extending pressure bar that is radially inwardly biased to urge the inner circumferences of all the springs into contact with axially aligned points on the surface of the shaft. The springs are then compressed using a compression element while they are still urged by the pressure bar against the shaft. Finally, to retain the springs on the shaft and maintain the springs in compression, a split retaining clip is pressed onto to the shaft until it engages in a groove.

  • Patent number: 8112856
    Abstract: A clamp of an anti-vibration spring includes a pipe body and a sheathing element fixed to an end the pipe body. Another end of the pipe body is fixed to a covering element. The sheathing element is passed through the external periphery of the pipe body. The pipe body includes a screw rod screwed at the moving element, and an end of the screw rod is protruded from an end of the covering element and fixed at a driving element. A connecting element between the sheathing element and the moving element positions the sheathing element and the moving element. Each sheathing element has a connecting portion including a transversal slot, two clamping disc, and an insert portion on the clamping disc connected to the transversal slot and fixed by a positioning element. By turning the driving element, the anti-vibration spring is compressed or released between the two clamping discs.

  • Patent number: 7966911
    Abstract: A hose clamp compression tool for engaging and compressing opposed or opposite end tangs of a hose clamp includes a first fixed plate and jaw and a second fixed plate spaced from the first fixed plate and jaw. The first and second plates are mounted on rails with a sliding plate and jaw also mounted on the rails and positioned between the fixed plates. The sliding plate is rotatably adjustable in spacing from the one fixed plate by means of a threaded rod journaled to the fixed plates and threaded to the sliding plate. The jaws each include both a transverse slot cooperative with an end tang of a band type hose clamp and a channel extending from the slot for engagement with the end tang of a ring or wire type hose clamp thereby enabling use of the tool for either a band type or a wire type hose clamp.

  • Publication number: 20100269325
    Abstract: An expansion tool is provided for manipulating a snap ring, comprising a handle defining a longitudinal axis, and a shaft connected with the handle along the longitudinal axis. The shaft is connected with the handle along the longitudinal axis. The shaft defines a front planar face disposed in a substantially perpendicular orientation relative to the longitudinal axis. A wedge extends from the shaft to a tip, and includes a first surface in substantial alignment with an outer surface of the shaft and a second opposing planar surface disposed in a substantially perpendicular orientation relative to the front planar face. The wedge further includes opposing engagement surfaces that each taper from the front planar face to the tip at an angle in a range of approximately 2 to 5 degrees. The engagement surfaces are tapered in a configuration to engage and expand a gap of the snap ring.
