At least some implementations of the present invention include the ability to access and secure a compressed riser portion of a pop-up sprinkler. Access is gained through use of the tip of the tool, sloped for access clearance between the sprinkler nozzle lip and outer sprinkler base. Once raised from the outer sprinkler casing, the riser is secured in a designated clamping bay or within designated clamping points. This two pronged approach accommodates varying diameter of sprinkler risers and increases the multi-use function of the tool. The tool's overall inward tension is provided by an engineered compression spring designed with adequate outward tension without making hand compression use of the tool restrictive. Use of the tool in an inward sweeping motion toward the sprinkler allows for raising and clamping the riser in a quick and simple fashion. Thereafter, allowing free and open-hand access for quick and thorough maintenance, repair, exchange or adjustment of the sprinkler nozzle and filter.

Tools for use in installing and removing V-clamps are disclosed. One embodiment of a V-clamp tool includes a spreader mechanism, an actuator cable, and a plier element mechanically coupled so as to expand or contract hooks shaped to engage corresponding V-clamp brackets to widen or shrink the V-clamp opening for installation or removal.

The invention relates to devices for attaching a temperature sensor to a pipe, comprising a first and second jaw for contacting the pipe; and a head slidably mounted between the jaws and having a third engaging portion for contacting the pipe and for retaining a first temperature sensor, the head being moveable between a closed position and an open position, in which the third engaging portion is closer to the first and second jaws in the closed position than in the open position. The jaws are moveable between closed and open configurations, in which the jaws are closer to one another in the closed configuration than in the open configuration. Motion of the jaws and the head is coupled so that the open configuration of the jaws corresponds to the open position of the head and the closed configuration of the jaws corresponds to the closed position of the head. The device may be arranged to bias the first temperature sensor against the pipe in the closed configuration. The invention also relates to a system of markings for indicating to a user whether the device is correctly attached to the pipe, in the form of bands, helixes, etc.

The present disclosure is directed to a coupling assembly for a turbomachine. The coupling assembly includes a liner and a sleeve at least partially positioned circumferentially around the liner. A frame is positioned between the liner and the sleeve. The frame includes a first side wall, a second side wall, and a base wall extending from the first side wall to the second side wall. A block is positioned between the liner and the sleeve and is movable relative to the frame to permit the block to move toward and away from the base wall. Moving the block away from the base wall causes the block to exert an inward force on the liner and the base wall to exert an outward force on the sleeve.

A universal tool holder configured for use with a machine tool is provided. The universal tool holder may be used for securing the machine tool in a relatively fixed orientation; for mounting and dismounting modular tools for milling and lathe computer numerical controls (CNC); and for assembling extension adaptors, reduction adapters, front clamp adapters, cutters, and other similar tools.

A clamp assembly and method of clamping includes a fixture having a cavity formed by a facing surface. The facing surface in the clamp assembly can define a cavity periphery. In addition, a recess can be provided in the facing surface. An elastic member can be disposed within the recess.

A pipe enlarging device includes a base, an operation unit and a clamping unit. The clamping unit is received in the base and includes movable front, rear, left and right clamps, multiple resilient members and a front threaded rod. The front, rear, left and right clamps are resiliently movable when the front threaded rod is rotated so as to form an adjustable clamping area between the front, rear, left and right clamps. The clamping area is used to clamp pipes of different sizes. The operation unit includes a top threaded rod with a cone-shaped member which is used to enlarge the inner diameter of the pipes.

The present disclosure discloses an internal and external clamping method and device of a thin-wall tubular part during rotary processing. A plurality of support blocks of this device are spaced to form an annular structure around the flange bush; the middle portion of each support block is provided with a through hole; a support claw is provided between every two support blocks, and the side surface of the support claw is provided with the through hole; a rotary shaft penetrates through the through holes in the support claws and the support blocks; the plurality of support claws are spaced to form a support claw ring having the annular structure, and each support claw is formed by connecting the front end, the rear end, and the bottom; the support claw ring is provided in a clamping cylinder, and the thin-wall tubular part is provided between the outside surface of the support claw ring and the inside surface of the clamping cylinder. The clamping cylinder of the present disclosure is contracted under the combined action of a wedge-shaped sleeve and a jacket, and is used for pressing the outer wall of the part, so that the external clamping of the thin-wall tubular part is realized; the support claw ring is turned over and expanded around the rotary shaft between the two support blocks separately, so that the internal clamping of the thin-wall tubular part is realized.

A clamp for use with an impact tool; the clamp having a nut for use with impact tools includes a screw on top, a safety handle, and a hole for carabiner clip. In use, a user adjusts the top screw to a length option desired, such that it doesn't slide onto object to be clamped. The clamp further comprises a grip on the safety handle. The clamp provides faster and more efficient use when using an impact tool.

A holding apparatus for holding a workpiece, which has a round and/or tubular cross section and is to be machined, in such a way that, in the held state, the workpiece can be rotated in relation to the holding apparatus, having at least two clamping arms, which are mounted in a pivotable manner on a base part and by means of which a clamping force can be exerted onto the workpiece, and having an adjustment mechanism for the clamping arms. Provision is made for the adjustment mechanism to have at least two drivers which are guided in a straight line, it being possible for the clamping arms to be pivoted or the clamping arms being pivoted toward one another by virtue of the movement of the drivers, wherein the drivers are arranged one behind the other as seen transversely in relation to the direction of movement of the drivers.
