Utilize the device of the utility model to measure railway curve line mileage, has reduced the work load and has improved the work efficiency, and the railway line mileage measuring device of the utility model is especially suitable in mountainous area is not suitable with the use under the environment of GPS measurement.

The invention discloses a space dilator for an oral endoscopic thyroid surgery, and relates to the technical field of medical apparatus and instruments, the space dilator comprises an oral cavity internal dilation assembly, and under the cooperation of the oral cavity internal dilation assembly, a flexible guide tube and a magnetic rotating ring, under the cooperation of a miniature pressure integrated detection sensor, the oral cavity internal dilation assembly and the flexible guide tube are connected with the magnetic rotating ring; the pressure of the expansion adjusting assembly on the tissue is monitored in real time and automatically fed back so as to be used for adjusting the strength and avoiding excessive compression, the positioning navigation edge connecting piece ensures that the position of the edge connecting sliding soft bag is accurate, follow-up medical operation is facilitated, and the frequency and amplitude of ultrasonic waves generated by the micro ultrasonic generator are utilized so that the operation efficiency can be improved. The displacement magnetic lantern ring piece is controlled to drive the magnetic rotating ring to move outside the flexible guiding pipe, the expansion adjusting assembly is made to synchronously and sequentially make the size be adjusted in a sliding mode along the outer portion of the sleeve according to the size from large to small, the influence on a patient due to the inaccurate expansion position during space expansion is effectively reduced, and the patient experience is improved. And the operation requirements and comfort are met.

This utility model relates to the field of semiconductor equipment assembly technology, and more particularly to a pre-assembly device for multi-laser positioning. It includes a pre-assembly platform, on which a laser level for monitoring the origin is fixedly mounted. An X-axis guide rail and a Y-axis guide rail are also fixedly mounted on the pre-assembly platform. Uniformly distributed X-axis sliders are slidably mounted on the X-axis guide rail, and uniformly distributed Y-axis sliders are slidably mounted on the Y-axis guide rail. This utility model allows for convenient and rapid positioning of the X and Y coordinates of multiple pipe fittings using the X and Y axis guide rails, which is much faster than aligning each one individually with a laser level. The X and Y axis guide rails contain scales, and the X and Y axis sliders contain coordinate pointers, which conveniently indicate the current coordinates of the sliders. By creating reticles on the base plates of positioning height scale one and positioning height scale two, the X and Y axis laser beams can be easily aligned with the reticles to determine the coordinates. This device offers good versatility for pre-assembling pipes for different semiconductor devices.

The utility model belongs to the field of lighting street lamps, and particularly relates to an internet-of-things landscape lighting street lamp with a direction indicating function, which comprises a lamp post, a mounting seat is fixedly connected to the bottom of the lamp post, a mounting hole is formed in the mounting seat, and a mounting frame is fixedly connected to the right end of the lamp post. A lamp holder is fixedly mounted at the lower end of the mounting frame, and a fixing seat is fixedly connected to the top of the lamp post. By designing the solar panel, the purpose of auxiliary power supply can be achieved for the street lamp, in the using process of the solar panel, under the action of the motor, the rotating disc and the rotating base can be driven to rotate, then the using position of the solar panel can be adjusted in a rotating mode, the static rotating disc can be limited under the inserting fit of the clamping ball and the groove, and therefore the solar panel can be conveniently used. Therefore, the rotating seat and the solar panel can be limited, and the solar panel is prevented from rotating and shaking under the influence of wind power to influence the stability.
