The present disclosure relates to the technical field of geotechnical engineering. An embodiment of the present disclosure provides a geotechnical engineering drilling device, including a base platform. A support is fixedly installed on the top of the base platform. A moving plate is movably installed inside the support. A first motor is fixedly installed on the top of the moving plate. A drill pipe is rotatably installed at the bottom of the moving plate. In the present utility model, through the rotation of the rotating plate, the reinforcement pile is drilled into the soil. Then, through the rotation of the rotating rod, the casing is displaced downward. The downward displacement of the casing will squeeze the reinforcement block into the soil through the slope surface of the reinforcement block, completing secondary reinforcement. Compared with traditional devices, this device can fix the base platform through the reinforcement pile and can also increase the contact area between the reinforcement pile and the soil through four groups of reinforcement blocks. Through the above technical solution, the technical problems of poor fixing effect and easy deviation of the drill pipe in the prior art are solved.

The utility model discloses a cutting device for wood board processing, including frame, the upper portion fixed penetration of frame has first electric telescopic handle, the upper portion sliding penetration of frame has two groups of guide rod, and the telescopic end of first electric telescopic handle and the lower extreme of two groups guide rod are installed with concave frame, and the inside of concave frame is provided with the mounting shaft, both sides of concave frame all are installed with drive motor, and the output of two groups drive motor is connected with the both ends of mounting shaft through the shaft coupling respectively, the inside of frame is installed with a plurality of support rollers through bearing, the inside of frame is provided with two groups of concave board and two groups of concave seat, and the inside of two groups concave board all is installed with a plurality of limit rollers through bearing. Advantageous effects: the utility model has adopted concave frame and mounting shaft, through setting concave frame and mounting shaft, possesses multiple cutting structure, can realize the multistage cutting of wood board fast, has improved the working efficiency of cutting device for wood board processing.

The application discloses a micro switch and a car gauge level connector, and belongs to the electrical technical field, wherein the micro switch comprises a fixed seat, a movable seat, a driving part and a normally open contact component; at least two wiring terminals are arranged on the fixed seat; the movable seat is used for abutting against an external part and is movably arranged in the fixed seat through the driving part; and the normally open contact component is moved through the movable seat to complete closure and conduct each wiring terminal. The fixed seat can limit and guide the movable seat, thereby preventing the movable seat from shaking during movement, effectively avoiding deviation and dislocation of the normally open contact component during closure or opening, and enabling each contact to stably abut against each other, so that the reliability and stability of circuit conduction are remarkably improved. The application reduces the number of parts, simplifies the overall structure, is simple to assemble, saves time and labor, improves production efficiency, and is convenient for repair and maintenance.
