A plastic clip attaches to a gun sling, and assists in the carrying of a gun over the shoulder. The gun sling is an ordinary strap that attaches to the gun and loops over the shoulder. The clip attaches to the strap, and hooks into the waist belt. The clip allows the waist belt to support much of the weight of the gun, and keeps the gun from flopping around. The gun is further stabilized by a bungee cord that connects the clip to a belt loop.

A tote device comprising a compartment for storing recreational equipment and a strategically located holding mechanism for the placing of weighty objects, wherein said strategically located holding mechanism is placed such that the weight of a weighty object is distributed to lessen the weight load borne by a user. The strategically located holding mechanism is preferably a platform attached outside of the compartment. When a weighty object is placed on the strategically located holding mechanism and the tote device is in position for transporting the recreational equipment to a remote location, the strategic placement of the weighty recreational equipment will act to reduce the weight burden borne by the user.

A packable battering ram quickly disassembled for transport by two or more persons. In the preferred embodiment, the invention has first and second body members that are symmetrical, but otherwise identically shaped and sized. When assembled, the first and second body members form a lower surface that has a concave portion that approximates the natural curvature of the back of an adult male. The packable battering may be disassembled to distribute the weight between multiple people, yet quickly assembled for use upon arrival at a emergency response location.

The invention discloses a coaxial helicopter control system with the parallelism of upper and lower rotor wing inclinators being changeable. The upper rotor wing inclinator is mounted below a reduction box. An upper rotor wing is controlled through a control long pull rod located in an inner shaft. The lower rotor wing inclinator is mounted above the reduction box to control a lower rotor wing. Longitudinal and transverse operation and heading operation are simultaneously conducted through five steering engines. Longitudinal control is achieved through the two longitudinal steering engines. The two inclinators are longitudinally and synchronously changed through control connecting rods. Transverse control of the upper and lower rotor wing inclinators is achieved through independent upper and lower rotor wing transverse steering engines correspondingly. Transverse nonparallelism of the upper and lower rotor wing inclinators is changed, and meanwhile, transverse control is conducted. Heading control is achieved in the mode that a heading control slide ring is controlled by a heading steering engine to move up and down, and movement is transmitted to lower rotor wing variable-pitch pull rods through a heading control supporting rod and a heading coordination lever. By adoption of the coaxial helicopter control system, changes of the transverse nonparallelism of the upper and lower rotor wing inclinators can be achieved, and the phenomenon that transverse upper and lower rotor discs obliquely get close even propellers hit with each other is improved.

The invention discloses an automatic mechanical lifting tool, relates to the technical field of mechanical lifting tools. The invention aims to solve the problems that the existing stability is poor and the grabbing is not firm. A first inclined arm and a second inclined arm are arranged inside a lifting tool frame correspondingly, a first clamp arm is mounted below the first inclined arm, a hookring is arranged on one side of the lower end of the first clamp arm, a second clamp arm is mounted below the second inclined arm, a fixing ring is arranged on one side of the lower end of the secondclamp arm, a fixing base is arranged at the middle position of the bottom of the lifting tool frame, an air cylinder is mounted below the fixing base, a fixing frame is arranged below the air cylinder, a connecting shaft is arranged at the lower end of the fixing frame, locking pins are arranged on the two sides of the upper end of the lifting tool frame, lifting rods are arranged at the upper part of the lifting tool frame, a lifting plate is arranged at the upper part of the lifting rods, buffering blocks are arranged on the two sides of the interior of the lifting plate, connecting rods arearranged outside movable shafts.

The invention discloses a sensor mounting seat with cooling function, which is composed of a platform, a cylindrical boss and a sealing ring coaxially assembled together, wherein the cylindrical boss is hollow and the wall is provided with at least two vertical air passages , the sealing ring is connected to the bottom of the cylindrical boss and forms a horizontal annular groove that leads to all the ventilation grooves; The air holes and air passages are intersected and conducted one by one, combined with the horizontal annular groove to form the air flow passage space inside the sensor mounting seat. After applying and implementing the technical solution of the present invention, through self-cooling structure improvement and cooling treatment, the mounting seat can be made of ordinary nickel-based alloy to meet the mechanical strength requirements for use in a high-temperature gas environment of about 1600K, effectively reducing its surface temperature and weakening The measurement accuracy of the thermocouple compensation wire is out of tolerance due to temperature overrun, which reduces the weight burden and cost of the aero-engine.
