This invention relates to the field of bridge construction technology, specifically to a method for installing inclined steel reinforcement components of a four-tower bridge. The method includes the following steps: S1, pre-biasing the nth segment of the steel reinforcement component; S2, initial positioning of the nth segment of the steel reinforcement component based on a guide sleeve; S3, applying tension to the hoisted nth segment of the steel reinforcement component, and adjusting its posture by measuring its inclination angle; S4, after all main reinforcement bars are connected, concrete is poured, and after pouring, an error adjustment scheme for the (n+1)th segment of the steel reinforcement component is obtained; steel wire ropes are connected to the nth and (n-1)th segments of the steel reinforcement component, and tightening the steel wire ropes applies tension to the (n-1)th segment of the steel reinforcement component. This invention, through monitoring and adjustment, helps to achieve rapid positioning of the steel reinforcement component, ensures the accuracy of the component's spatial posture, and significantly saves manual adjustment time.

The present disclosure provides a medical water jet instrument and a medical water jet system. The medical water jet instrument comprises an outer tube, a nozzle, a nozzle and a fluid driving device. The nozzle extends through the outer tube and is configured to input medical liquid at the proximal end. There is a gap between the outer wall of the nozzle and the inner wall of the outer tube. The nozzle is fixed at the distal end of the nozzle and is configured to output medical liquid. The fluid driving device comprises a fluid inlet, a moving part, a cavity and a shell surrounding the cavity, at least part of the moving part is built into the cavity, the fluid inlet is for fluid to flow in and is connected with the cavity so that the fluid flows into the cavity, the moving part is connected to the nozzle and the moving part is driven to move by the fluid flowing in the cavity, driving the nozzle to rotate or swing. The medical water jet instrument disclosed in the present disclosure drives the nozzle in the outer tube to move by a fluid driving method, which can not only realize automatic scanning, but also has the advantages of light weight, low cost, small size, low noise and no need for electrical connection.

This utility model discloses a controller and an atomizer assembly. The controller includes a support part and a connector part. An electrical plug is provided on the connector part, which can be inserted into the pin of the atomizer. The bottom of the support part is recessed downwards to form a support surface that adapts to the outer contour of the atomizer connection part. A retractable stop is provided on the support surface. When the stop extends, it abuts against the side of the atomizer connection part away from the connector part to clamp and constrain the connection part. When the stop retracts, the clamping constraint is released. This utility model eliminates the traditional cable connection between the atomizer and the controller through a direct pin-plug connection, improving operational convenience. This utility model can simultaneously achieve dual positioning of electrical connection and mechanical locking, forming a stable connection between the atomizer and the controller.
