A tool for use in preloading a bearing includes a plurality of arms pivotable relative to each other and a pin extending from each arm of a plurality of arms. The pin is configured to engage an opening of a plurality of openings in a retaining ring. A resilient member biases the plurality of arms away from each other. A first arm of the plurality of arms includes a cavity. A second arm of the plurality of arms is received in the cavity such that an extending portion of the second arm extends outside the cavity and the second arm is moveable in the cavity.

A pair of circlip pliers includes two handles, two jaws and two switching boards. The handles are symmetrical to a longitudinal axis and are arranged at a horizontal interval. The jaws are symmetrical in shape, are mounted between the handles, abut each other, and are pivotally connected with the handles. The switching boards are respectively and pivotally connected with the handles. The pair of circlip pliers can be applied as an expanding type circlip plier or a squeezing type circlip plier to allow a user to change the state of the pair of circlip pliers for different purposes.

A plier tool for expanding a friction ring having a first opposing end and a second opposing end can include a first arm including a distal portion comprising a first protrusion extending distally from a central axis and a first projection extending outwardly from the first protrusion away from the central axis, the first projection configured to engage the first opposing end of the friction ring; and a second arm including a distal portion comprising a second protrusion extending distally from the central axis and a second projection extending outwardly from the second protrusion away from the central axis, the second projection configured to engage the second opposing end of the friction ring.

The present invention discloses a snap spring dismounting and mounting tool, including: an outer housing; a dismounting and mounting assembly, two ends of which can be detachably clamped in the outer housing, respectively; a pressing rod, which is movably disposed on the outer housing and can be in contact connection with or disengaged from the dismounting and mounting assembly; and an elastic member, which is disposed in the outer housing, is in contact connection with the pressing rod, and provides a biasing force and a restoring force to the pressing rod, respectively, where the dismounting and mounting assembly includes a connecting mechanism, and a first clamping plier body and a second clamping plier body that are movably disposed on the connecting mechanism relative to each other; the first clamping plier body and the second clamping plier body have a gap disposed therebetween.

A C-clip tool includes a first part and a second part. A first arm and a second arm are connected between the first and second parts. The second part has a reception hole and a rod is located at the mediate portion of the reception hole. Two enlarged holes are located on two ends of the reception hole and communicate with the reception hole. A resilient plate is located in the reception hole and two pillars are connected to the resilient plate. A push member has a block which optionally contacts one of the two pillars. Two operation members are respectively connected to the first and second arms. The operation members are replaceable to operate on different sizes of C-clips.

A pliers switchable for use with external snap-rings and internal snap-rings is disclosed. A jaw assembly with easily changeable tips is provided, and to be more convenient for the end-user, a spring loaded tip release mechanism and jaw assembly is provided.

A pair of pliers includes two handles and a latch unit. The handles are pivotally connected to each other. The latch unit includes a pawl, a rack, a spring and a switch. The pawl is secured to the first handle. The rack is pivotally connected to the second handle. The spring biases the rack into engagement with the pawl. The switch is movable between two positions. In the first position, the switch allows engagement of the rack with the pawl. In the second position, the switch keeps the rack from the pawl.

A circlip tool includes a first actuation lever, a second actuation lever, a first tip, and a second tip. The first tip and the second tip are each configured for insertion into one installation hole in a circlip. The first tip is rigidly secured in the first actuation lever, and the first actuation lever and the second actuation lever are borne so as to be pivotable relative to one another. The circlip tool also includes a cam gear, which has a cam borne so as to be rotatable relative to the first actuation lever and a follower borne so as to be displaceable relative to the first actuation lever. The second tip is borne so as to be displaceable relative to the first actuation lever and is kinematically coupled to the follower. The second actuation lever is connected to the cam in a rotationally engaged manner.
