This utility model discloses an adjustment device for the length of explosive charge, including a chassis, a vertical rod fixed on the chassis, a slider slidably sleeved on the vertical rod, a horizontal rod slidably sleeved on the slider, a fixed block hinged to one end of the horizontal rod, an angle adjustment mechanism for adjusting the angle of the fixed block installed on the horizontal rod, a fixed rod fixedly sleeved inside the fixed block, and a measuring rod of equal length to the fixed rod slidably sleeved inside the fixed block, the measuring rod having graduation lines, and a positioning plate fixed to the bottom end of the measuring rod. The height of the measuring rod extending beyond the fixed rod is the height of the explosive charge to the bottom of the borehole, thus allowing adjustment of the explosive charge length as needed.
