The invention provides a loader distributed hydraulic system and a load.The loader distributed hydraulic system comprises a variable working pump, a variable steering pump, a flow distribution valve set, a movable arm inlet and outlet independent control valve set, a bucket inlet and outlet independent control valve set, a large-displacement steering gear and a controller; the variable working pump and the variable steering pump output oil in the oil tank to the flow distribution valve set, and the flow distribution valve set is communicated with the movable arm inlet and outlet independent control valve set, the bucket inlet and outlet independent control valve set and the large-displacement steering gear. The movable arm inlet and outlet independent control valve group, the bucket inlet and outlet independent control valve group and the large-displacement steering gear are respectively communicated with the movable arm oil cylinder, the bucket oil cylinder and the steering oil cylinder; the controller is used for controlling the flow and distribution of hydraulic oil when the pump machine valve group works. According to the hydraulic system, the energy-saving effect of the loader can be improved, loads do not interfere with one another when the movable arm oil cylinder, the bucket oil cylinder and the steering oil cylinder act in a composite mode, and the operation comfort is better.

The application discloses a portable adjustable pipe supporting and carrying trolley, and belongs to the technical field of carrying trolleys. The trolley comprises a trolley frame, two running wheels and a gripping handle. The two running wheels are respectively arranged on the two sides of the trolley frame. The gripping handle is arranged on the middle part of the trolley frame. An extension part is fixedly arranged on the top of the trolley frame. A center rod is fixedly arranged on the top of the extension part. Pipe tongs are rotatably connected to the two ends of the center rod. A working cavity is arranged between the center rod and the extension part. A rotating handle is movably arranged on the side wall of the extension part. A placing groove is arranged on the side wall of the extension part. A rotating mechanism for driving the two pipe tongs is arranged in the working cavity. The pipe tongs clamping and the trolley carrying are combined, portable clamping and carrying of pipes with different diameters are realized, the labor intensity is effectively reduced, and the pipe carrying efficiency and safety are improved.

The utility model discloses a writing pen which comprises a pen body with a refill and a pressing mechanism connected with the refill in a matched mode, a modeling unit is arranged at the top of the pen body and comprises a supporting body and an elastic modeling body connected to the supporting body, the elastic modeling body is arranged on the outer side of the supporting body in a covering mode, and at least part of the elastic modeling body forms a hollow cavity. The supporting body is provided with a flaring face used for opening at least part of the elastic modeling body. The supporting body not only plays a role in connecting the elastic modeling body, but also fully expands the elastic modeling body, the elastic modeling body can greatly deform under the action of stress extrusion, the effect of releasing pressure can be achieved when a user pinches the elastic modeling body by hands, and the decompression effect is good; the elastic modeling bodies are convenient to replace, a plurality of elastic modeling bodies can be used in a complete set, a user can disassemble, assemble and replace the elastic modeling bodies by himself according to needs, and the use interestingness is high.
