The utility model provides a kind of ladder handrail and ladder, it is related to ladder field, the ladder handrail includes handrail rod and the installation structure connected in the both ends of handrail rod, each installation structure is respectively included connecting seat and spin lock component;Two ends of handrail rod are installed in connecting seat;Spin lock component includes two rotary blocks, rotary rod piece, nut knob and elastic member;Two rotary blocks are located between the one side of connecting seat and are equipped with the elastic member;The section of two rotary blocks along rotary rod piece radial is all polygon, and the side surface of two rotary blocks mutually is the inclined plane or curved surface that mutually splices along rotary rod piece axial direction.The ladder includes preceding ladder handrail.The ladder handrail provided by the utility model can improve installation efficiency while realizing reliable locking, and can also be quickly disassembled according to needs, to quickly disassemble handrail to reduce the space occupied by ladder in storage and transportation process, avoid ladder to be damaged by knock, reduce transportation and maintenance cost.

The utility model discloses a textile fabric stretching mechanism which comprises a winding roller and fixing rings, the fixing rings are fixedly connected to the two sides of the winding roller respectively, a movable groove is formed in an inner cavity of each fixing ring, a clamping device is arranged in an inner cavity of each movable groove, and the side, away from the winding roller, of each fixing ring is rotationally connected with a support through a rotating shaft. A limiting device is arranged at the top of the side, close to the support, of the fixing ring, and a limiting groove used in cooperation with the limiting device is formed in the side, close to the fixing ring, of the support. The clamping device, the support and the limiting device are used in cooperation, the push rod is pushed, the push rod pushes the fixing block to move, the fixing block stretches the tension spring, meanwhile, the fixing block drives the clamping block to move through the connecting block, fabric is placed on the surface of the winding roller, the push rod is loosened, and the fixing block is driven by contraction force generated after the tension spring is stretched to move reversely; the problems that when an existing textile fabric is processed, wrinkles are likely to be generated on the fabric, and consequently defective products appear in the subsequent processing process are solved.

The invention provides an intrauterine precise guiding, conveying and insemination device, which relates to the technical field of medical apparatus and instruments, and comprises a suction and conveying unit, a rotary insemination unit and a driving auxiliary unit, the rotary insemination unit is installed at the left end of the sucking and conveying unit, and the rotary insemination unit is used for sucking fluid containing sperms and conveying the fluid containing sperms into the uterine cavity; the driving auxiliary unit is installed on the rotary insemination unit, and the suction conveying unit and the driving auxiliary unit are used for improving the conveying precision of the rotary insemination unit; when two rows of arc-shaped pushing blocks push two movable increasing frames to slide inwards, air in a rectangular pressurizing shell enters a driving air bag, automatic driving of a rotary insemination head is achieved, and the conveying direction of fluid containing sperms can be automatically changed; the problem that when fluid containing sperms is conveyed, the conveying position cannot be automatically changed, and the fertilization success probability is affected is solved.
