Abstract

The utility model discloses a pulling and grabbing set for a horizontal machine tool. The pulling and grabbing set comprises a main shaft core, a locking nut assembly, a first fixing sleeve, a cutter assembly and a pulling claw assembly. The pulling claw assembly is arranged in the spindle core, the bearing tool locking seat is fixed through the protruding part of the pulling claw piece by means of cooperation between the pulling claw piece and the grabbing rod, and therefore primary fixing of the tool assembly is completed, and further through cooperation between the connecting rod and the grabbing rod, the bearing tool locking seat is fixed. The grabbing rod is used for grabbing a cutter handle blind rivet of the cutter assembly, so that the cutter assembly is further fixed, a cutter can be more stably fixed in the spindle core, the working stability of the cutter assembly is enhanced, a workpiece is more stably machined, the cutter is prevented from falling off, and the working efficiency is guaranteed.
