The present invention discloses an extrusion apparatus for high viscosity liquid to address the problems that the existing extrusion apparatus tends to be abraded for long-time use and the high viscosity liquid could not be well extruded. The extrusion apparatus for high viscosity liquid of the invention comprises a gun body, a retainer fixedly connected to the gun body, a push rod slidably running through the gun body, a wrench hinged to the gun body and a handle connected to the gun body, characterized in that, a push block is hinged to one end of the wrench adjacent to the push rod, the push rod has a rod body provided with several teeth on the side facing the push block, a push tooth is provided on the push block, a permanent magnet is placed on the push block or the push rod, and the push tooth could be snapped to the teeth under action of the magnetic force of the permanent magnet.
