The invention provides a universal folding type automatic driving small vehicle. An intelligent terminal is arranged at the bottom of a small vehicle base, and a base extending plate is installed at one side of the small vehicle base in an inserting mode, wheel shafts are arranged at the other side of the small vehicle base and the lower portion of the movable end of the outer side of the base extending plate, driving wheels are arranged at the two ends of each wheel shaft, a first camera position adjusting rod and a second camera position adjusting rod are arranged at the outer side of the other side of the small vehicle base, the other end of the second camera position adjusting rod is fixed to the outer side of the small vehicle base, the upper end of the first camera position adjusting rod is connected with a probing camera, a rear side plate is arranged at the upper portion of the other side of the small vehicle base, a front side plate is arranged at the movable end of the outer side of the base extending plate, and side plate extending plates are installed at the upper ends of the rear side plate and the front side plate in an inserting mode. By designing a folding type automatic driving small vehicle, when not in use, the small vehicle can be automatically folded and deformed and therefore is convenient to carry and place, and when in use, the small vehicle is deformed and stretched and can be automatically driven; the universal folding type automatic driving small vehicle is particularly suitable for transporting and carrying plate type parts and can be used for transporting plates and transporting military supplies.

The invention relates to a material conveying device for construction. The material conveying device at least comprises a first horizontal conveying part arranged in a tunnel, a vertical lifting partarranged in a vertical shaft and a second horizontal conveying part arranged on the ground surface. The first horizontal conveying part is arranged at the intersection of the tunnel and the vertical shaft. The vertical lifting part can convey ballast soil from the first horizontal conveying part to the second horizontal conveying part in a redirection conveying mode. The first horizontal conveyingpart is arranged at the intersection of the tunnel and the vertical shaft, and the position of the first horizontal conveying part is kept unchanged. When the length of an extending conveying part needs to be increased, only construction operation needs to be conducted at the bottom of the vertical shaft, the transportation cost of operation tools and materials is low, and due to the fact that the operation area of an excavating device is far away from the vertical shaft, operation of the excavating device is not affected, and the tunneling speed of the tunnel can be effectively guaranteed.

An electric stapler is operated by the steps of: a paper bundle pinching step of relatively moving a table part and a driver unit and also pinching a paper bundle; a staple separation step of folding a staple into U-shape by a forming plate and also separating the folded U-shape staple from a staple sheet by moving a driver; a penetration step of penetrating legs of the staple into the paper bundle by further moving the driver; a clinch step of inward folding the legs penetrating through the paper bundle by a clinch device; and a paper bundle releasing step of releasing the paper bundle. A relative movement of the table part and the driver unit, the forming plate, the driver, and the clinch device are powered by a single motor. A driving speed of the motor in the steps excluding the penetration step and the clinch step is slower than the driving speed of the motor in the penetration step and the clinch step.
