[0002] The gate is one of the essential core components of the entire water conservancy project. The gate is usually a movable structure used to open and close the water inlet in a partial hydraulic structure, and it can play roles such as regulating the flow rate and controlling the water level. During the production and manufacturing process of the gate, a magnetic drill is also required for drilling.

[0003] For example, a magnetic drill for drilling of gate processing with the publication number of CN210615226U includes a machine body, a magnetic base fixed to the bottom of the machine body, and a guide rail vertically opened on the side of the machine body. A guide block is slidably connected in the guide rail, and a handle for controlling the up and down movement of the guide block is connected to the machine body. By making the magnetic drill in a horizontal state inside the gate, the influence of the overall height of the magnetic drill is avoided, which facilitates the operation of the staff on the magnetic drill inside the gate, makes the drilling part inside the gate neater, and improves the work efficiency.

[0004] When the magnetic drill proposed in the above patent document is in use, only the motor is used to drive the drill bit to rotate to adjust its drilling direction, but there is no structure for positioning the drill bit after rotation, which easily causes the drill bit to deviate and be unstable during the drilling process, affecting the drilling quality, and the device is not convenient for the staff to accurately position the angle of the drill bit, lacking practicality.
