The utility model relates to a motorcycle stepless speed change clutch, concretely relates to a moving wheel bushing structure, including moving wheel, bush, the moving wheel has the central hole, the moving wheel central hole is provided with the shaft sleeve in interference fit, the bush interference fit is arranged in the shaft sleeve, adds the shaft sleeve structure between the moving wheel central hole and the bush, and the shaft sleeve has the safe interference amount with the moving wheel, and will not be loose, and the thermal expansion coefficient of the bush and the shaft sleeve is consistent, and will not be loose and turn, so can effectively prevent the bush thermal expansion loose, wear, exit problem, increased the reliability of the clutch, greatly improved the life of the clutch.

The utility model discloses a vascular puncture dilator for ECMO relates to dilator technical field. Specifically including dilatation spare and adjusting spare, dilatation spare is a hollow cylinder, and it has open line one in length direction, adjusting spare sets up in the inner wall of dilatation spare, and it is equipped with the open line two of placing guide wire in length direction, wherein, adjusting spare can rotate relative to the axis of dilatation spare, and make open line two and open line one can be selected coincident, to with guide wire from open line two and open line one separate. Dilatation spare and adjusting spare are provided with open line one and open line two respectively, and guide wire can move from open line one to open line two, when open line two and open line one coincide, dilatation spare removes the puncture part, can directly from guide wire on the change, avoided the dilator and needed the guide wire to exit, reduced the time of dilator from guide wire and took out, reduced the amount of bleeding of patient blood vessel after dilatation.

This utility model relates to the field of high-voltage power transmission and distribution technology, and discloses an adjustable-capacity high-voltage series compensation device, including a core compensation unit, a bypass protection unit, a damping circuit, and a control system. The core compensation unit has at least two parallel capacitor branches controlled by independent switching switches for step-wise adjustment of the compensation capacity. The control system includes a safety interlocking system, which includes a first interlocking module and a second interlocking module that are independent of each other. The first interlocking module is used to forcibly lock all independent switching switches in the open state when the bypass switch is closed; the second interlocking module is used to prohibit operation of the incoming and outgoing line isolating switches of the device when the bypass switch is not closed. This utility model, by combining hardware forced interlocking with intelligent control, eliminates the risk of misoperation and significantly improves the safety, reliability, and adaptability of the device operation to the power grid.
