Profile core-pulling device

The invention relates to a core pulling device, in particular to a profile core-pulling mechanism. A profile core-pulling device comprises a desk table and a core pulling mechanism arranged on the desk table. The core pulling mechanism comprises a transmission mechanism and a cable wound on the transmission mechanism. The tail end of the cable is fixedly provided with a clamping handle. The transmission mechanism comprises a shaft, a bearing, a bearing base and a handle. The bearing is provided with a bearing outer ring and a bearing inner ring rotating relative to the bearing outer ring. The bearing is arranged in the bearing base. The bearing base is fixed to the desk table. The bearing outer ring is fixedly arranged in the bearing base in a sleeving mode. The shaft is fixedly arranged in the bearing inner ring in a sleeving mode. The handle is fixedly arranged on the shaft in a sleeving mode, and the cable is wound on the shaft. The profile core-pulling device has the advantages that a profile core in a profile with the profile core to be pulled can be pull out conveniently and easily, and core pulling efficiency is improved.
