Abstract: The present disclosure provides a magazine loader for loading a cartridge into a magazine. The magazine loader has a housing, a stopper, a cartridge loading slide and a guider mounted on the housing. The housing has a recessed portion as a magazine opening for receiving at least a portion of the magazine. The recessed portion of the housing has a front wall, a rear wall and a rear wall with a cartridge opening. A cartridge loading slide with an angle relative to a horizontal line is located on the bottom wall of the recessed portion. The cartridge loading slide has a linear channel aligned with the cartridge opening, a length of the linear channel is less than a distance between the front wall and the rear wall and greater than a width of the magazine.

Abstract: The present invention provides an auxiliary bullet loader for a magazine, which includes a housing, wherein the housing is provided with a mounting space for accommodating a magazine, a first swinging mechanism is connected to a top portion of the housing, the first swinging mechanism includes a first pressing plate, the first pressing plate includes a first engaging end, the first engaging end extends obliquely downwards into the mounting space, and a bullet inlet of the magazine when the magazine is loaded into the mounting space faces upwards, the first engaging end is inserted into the magazine and swings relative to the housing under an action of the magazine, thereby pressing a follower within the magazine.

Abstract: A connecting rod of an internal combustion engine, including a small end and a shank. The small end employs a flexible structure made of hard material. The hard material is a steel or alloy material having a tensile strength greater than or equal to 700 megapascal. The small end of the flexible structure includes a circular body, a center hole, and a flexible support. The circular body encircles the center hole, and the center hole is a complete circular hole having a constant diameter. The small end matches with a piston pin. The flexible structure of the small end operates to allow an elastic deformation of the center hole along an axial direction thereof produced by cylinder pressure exerted on the piston pin to adapt to a bending deformation of the piston pin along the axial direction.
