This utility model relates to the field of dual-axis slide cylinder technology, specifically a dual-axis precision slide cylinder, including a precision slide cylinder body. Two piston rods are slidably mounted at both ends of the precision slide cylinder body. A cylinder fixing plate is fixedly connected to one side of the two piston rods. Two semi-circular arc plates are fixedly provided on the outer surface of the piston rods. Cleaning cotton is arrayed inside the two semi-circular arc plates. Circular grooves are opened on both sides of the two semi-circular arc plates. Through the cooperative design of the semi-circular arc plates and cleaning cotton, this utility model can automatically remove dust from the surface of the piston rods when they extend and retract, reducing the impact of dust accumulation on transmission accuracy. The spring-driven snap-fit ​​structure facilitates quick disassembly and assembly of the semi-circular arc plates and convenient periodic replacement of the cleaning cotton, ensuring a long-term stable dust removal effect.

The invention relates to a component mounting assembly in a power transformation cabinet and the power transformation cabinet, the mounting assembly comprises a sliding frame, an insertion frame, a rotating plate, a mounting frame, a sliding block and a connecting rod, the sliding frame is fixed in the power transformation cabinet, the insertion frame is slidably mounted on the sliding frame, the rotating plate is rotatably mounted on the insertion frame, the mounting frame is fixed on the rotating plate, and the sliding block is slidably mounted on the insertion frame. And the other end of the connecting rod is fixedly connected with the rotating plate. Compared with the prior art, the power transformation cabinet has a sliding and rotating multi-stage movement structure, the mounting positions of components in the power transformation cabinet can be flexibly adjusted, the overall position can be adjusted through sliding along the sliding frame, the components can be overturned through the rotating plate, the adjusting flexibility is high, and the practicability is high. The problem that the maintenance and wiring operation space of a traditional fixed installation mode is limited is solved, installation of large components can be met, and meanwhile the stability of rotation adjustment is guaranteed through a connecting rod linkage structure.

The invention discloses a squirrel-cage seedling taking structure for planting, belongs to the technical field of agricultural machinery, and aims to solve the technical problems of relatively complex structure and relatively low seedling taking efficiency of a pot seedling mechanism in the prior art. The device comprises a driving assembly, the driving assembly comprises a plurality of chain boxes, each chain box is provided with a corresponding power input end and a corresponding power output end, and the power input ends and the power output ends are connected through a transmission belt; the seedling taking assembly is used for moving pot seedlings into the seedling planter from a pot disc and comprises a main motion control disc, an auxiliary motion control disc and a plurality of seedling taking rods, one end of each seedling taking rod is connected with the main motion control disc through a crankshaft, and the other end of each seedling taking rod is connected with the auxiliary motion control disc; a plurality of seedling taking units are arranged on the seedling taking rod. The squirrel-cage type seedling taking structure for planting can be adjusted and designed at will according to agricultural requirements so as to meet the agricultural requirements for line spacing, and is convenient to adjust and high in seedling taking working efficiency.
