An extracting tool for extracting a metal piece located in an aerodynamic stream of a turbomachine, such as a flow splitter nose, includes a rod; a first stop located at a distal end of the rod and provided with a claw for bearing against a first edge of the metal piece; a gripping member translationally mounted to the rod and including a first projecting portion arranged to receive a second, opposite edge of the metal piece; a tightening mechanism configured to keep the gripping member bearing against the metal piece and the first stop.

This hydraulic drilling apparatus including a casing comprising a front part, a shank including a fluid injection conduit and intended to be coupled to at least one drill rod equipped with a tool, the shank, a striking piston slidably mounted inside the casing along a striking axis (A) and configured to strike the shank, an extraction piston disposed around the shank and comprising an extraction portion configured to cooperate with the shank, and a cartridge removably mounted on the front part and disposed around the shank, the cartridge including an injection part configured to fluidly connect the fluid injection conduit to a fluid delivery conduit. The cartridge delimits a receiving housing in which the extraction piston is slidably mounted.

A hammer assembly has a guiding unit, an impacting block, and a fastening assembly. The guiding unit is elongated and has a body, a limiting portion, and a limiting unit. The body has a first end and a second end opposite the first end of the body. The limiting portion is disposed at the first end of the body. The limiting unit is disposed closely to the second end of the body. The impacting block is movably mounted around the body of the guiding unit and blocked by the limiting portion and the limiting unit of the guiding unit. The fastening assembly has a fastening seat connected with the second end of the body. The fastening seat has a positioning structure for fastening a tent peg. The positioning structure may be a receiving recess or a threaded hole.

An air hammer attachment having a support device extending between a first end and a second end. The first end has a threaded shaft and bolt. The second end having an inwardly extending rod and threaded bolt.

A prior art powered wrist pin knocker is improved with a new plunger that prevents wobbling. The new plunger responds to a return vacuum pressure. The improved plunger is symmetrical along a longitudinal axis. New embodiments include a new side mount valve head to reduce length, a remote air controller and a variable length cylinder for the cannon. The new valve head is a simplified valve head assembly that adapts to an end of the cannon mount or a side mount or a remote mount. Another embodiment provides a stand for a surface mount application. This embodiment can have an extended piston for loosening tail bearings down a long channel. A manual return embodiment can use a rod to manually return the plunger to the proximal end for another firing cycle.

A nail punching machine for driving in or pulling out rail spikes includes a driving mechanism, which is driven by an electric drive motor. The electric drive motor is supplied with electric power by an accumulator. The nail punching machine is held by an operator by at least one handle.

The present disclosure generally relates to quick change attachments for a pneumatic percussive tool. The attachments convert a pneumatic percussive tool, such as an air impact tool with proximal attachment, which has a “pushing” force, into a pneumatic percussive tool having a “pulling” force. Once attached to the pneumatic percussive tool, the attachments also provide a quick change feature for allowing “pulling” tools to be simply and easily removed and replaced.

A toolkit includes a rotation member, a driving member and an engaging member. The driving member is assembled in one side of the rotation member. The engaging member is assembled in another side of the rotation member. Wherein the driving member is rotatable relative to the engaging member by rotating the rotation member.

A dead blow slide hammer body with a through bore that receives and slides on a shaft. The hammer body includes one-or-more internal longitudinal cavities, lateral to the through bore, filled with a dampening material. When the hammer body sliding on the shaft strikes a slide stop, the dampening material creates a “dead blow” effect, increasing the duration of impact, while insulating a user from the shock.

A toolkit includes a rotation member, a driving member and an engaging member. The driving member is assembled in one side of the rotation member. The engaging member is assembled in another side of the rotation member. Wherein the driving member is rotatable relative to the engaging member by rotating the rotation member.
