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.

The invention discloses a mini folding bicycle, which comprises a vehicle body, a rear fork, a seat, a front fork, V-shaped folding handles, a front wheel, a rear wheel and a driving mechanism, and is characterized in that: the vehicle body comprises a beam tube, a front end tube, a five-way tube and a seat tube; the front end of the beam tube is connected with the front end tube; the bottom of the front end tube is connected with the five-way tube; the rear end of beam tube is connected with the seat tube; the back of the seat tube is connected with the rear fork; the V-shaped folding handles consist of handle base, left and right shafts, left and right handles, left and right quick releases, backing pieces, safety catches and internal expansion tubes; the driving mechanism consists of acentral shaft, a secondary shaft, two cranks, two pedals, a primary chain wheel, a primary minor sprocket, a secondary chain wheel, a primary chain, a rear chain and a flywheel; a front frame is connected with a front part of the folding base; the front fork is connected with the head tube of the vehicle body in a rotary manner; the V-shaped folding handles are connected with the front fork; the front wheel is arranged on the front fork; and the rear wheel is arranged on the rear fork.

The invention relates to a gear limiting method applied to heavy AMT vehicles. The method is characterized by comprising the following steps: (1), receiving gear limiting CAN bus information data and reading a limited gear value; (2) determining whether a current vehicle gear is greater than or equal to a gear value which is lower than the limited gear by three gears, turning to the step (3) if yes, or turning to the step (1); and (3) sending limited gear control information TC1 via the vehicle and sending information of an A / M mode and a P / E mode according to the received information, wherein the sent gear is a received gear value.
