Drilling positioning device

The invention discloses a drilling positioning device. The drilling positioning device comprises a drilling mechanism and a positioning mechanism. The drilling mechanism comprises a base, a support is fixedly connected to the top of the base, a movable plate is slidably connected to the inner side of the support, a through groove is formed in the movable plate, a motor is fixedly installed at the bottom of the movable plate, and a drill bit is fixedly connected to an output shaft of the motor through a main shaft. According to the drilling positioning device, the positioning mechanism is arranged on the drilling mechanism, the inserting plate can drive the protruding block to extrude the positioning rod after penetrating through the through groove, and therefore the positioning rod can be inserted into the groove under the reset effect of the spring to position the inserting plate, and then the positioning mechanism can be rapidly installed on the drilling mechanism; besides, regardless of the height of the w
