Abstract: A lubrication structure for a working machine is provided. A driven gear that engages with a driving gear connected to a driving source and rotates, is accommodated in a chamber in a case. An eccentric cam is provided on a surface of the driven gear, and connected to a coupling pin in a blade through a crank member. A fitting ring part is provided in one end of the crank member, and the eccentric cam is inserted into the fitting ring part so as to rotate relative to the fitting ring part. An annular groove is formed on the inner surface of the fitting ring part which faces the outer surface of the eccentric cam. The annular groove communicates with a first chamber via a first lubricating passageway and also communicates with a second chamber via a second lubricating passageway.

Abstract: A trigger assembly for switching one shoot mode or repeat shoot mode includes a trigger, a switch, a fixing element, a trigger plate and a torsion spring. When a user wants to switch the shoot modes of the nail gun, the user turns the switch so that the fixing element moves along the curved track of the switch and the fixing element drives the trigger plate to move on a protrusion or on a through hole simultaneously. After the user presses the trigger, the trigger plate is resisted by the protrusion so that the nail gun is in one shoot mode. In addition, when the trigger plate is vibrating on the through hole, the nail gun is in repeat shoot mode.

Abstract: An integrated module of a cylinder and reversing assembly of a reciprocating pneumatic tool is arranged between an air pressure control module and a guide outlet of a piston rod in a groove of the reciprocating pneumatic tool. The integrated module has a cylindrical body, an air pressure guiding seat positioned in the cylindrical body, a reversible actuating slot recessed into the seat body, a reversing brake block movably positioned into the reversible actuating slot, and a partition board fixedly assembled between the seat body and the cylindrical body.

Abstract: A capping device for capping vials borne by a respective conveyor (101), with caps (3) which include an inserting portion (31), shaped for insertion into a mouth of the vial (2) and a head portion (32), which remains externally on the vial (2) after capping. The capping device (1) includes a pick-up zone (12) configured for supporting and containing the caps (3) to be picked up by contacting only the head portion (32) thereof, a conveyor (11) for supplying caps (3) to the pick-up zone (12), configured to carry the caps (3) by contacting only a head portion (32) thereof; and a pick-up and inserting device (13) configured and activatable for picking up at least one cap (3) at a time from the pick-up zone (12), contacting only the head portion (31), and for holding the cap only by the head portion (302) while transporting the cap to a respective vial (2), and then inserting at least a part of the inserting portion (301) into the mouth of the vial (2).

Abstract: A forming assembly and process for forming a carton from a carton blank are herein disclosed. The finished carton can have an odd number of sides and/or an angle between two adjacent sides that is less than 90 degrees. The forming assembly includes a forming head and a forming cavity. The forming head acts as an inner die and the forming cavity acts as an outer die. In addition, the forming cavity includes at least one cavity side plate that desirably folds tabs on the carton blank to secure the tabs to one another and form the finished carton.
