The invention discloses a drilling 
machine for working continuously. The drilling 
machine comprises a foundation support, the foundation support is of a ladder shape, the upper portion of a first-grade step of the foundation support is slidably provided with a drilling 
assembly, the drilling 
assembly performs drilling operation on a 
mobile phone protection sleeve, and a continuous conveying 
assembly is arranged under the drilling assembly; the drilling assembly comprises a movement sliding block, the upper portion of the movement sliding block is provided with a supporting plate, and the supporting plate is of an L shape; and the two sides of the vertical portion of the supporting plate are provided with ribs correspondingly, the horizontal portion of the supporting plate is provided with a positioning groove, the upper portion of the positioning groove is fixedly provided with a drilling motor and a speed 
reducer in sequence, the upper portion of an output shaft of the speed 
reducer is provided with a 
drive wheel, and the front side of the vertical portion of the supporting plate is provided with a 
drill bit installation plate. By means of the drilling 
machine, a 
mobile phone protection sleeve can be machined and drilled continuously, the 
mobile phone protection sleeve is conveyed to the position below a 
drill bit through a continuous conveying assembly, a lifting positioning assembly performs lifting positioning on the passing mobile phone protection sleeve, then the 
drill bit drills the mobile phone protection sleeve, continuous 
machining is achieved, and material feeding is unintermittent.
