Abstract

The invention relates to a machine head liftable structure in a sewing machine, which comprises a machine head, a machine arm, a lifting board and two cylinders, wherein fixed seats are respectively arranged at both sides of the front end of the machine arm; linear guide rails are fixedly arranged at the front ends of the fixed seats; two sliding blocks are arranged on the linear guide rails; corresponding to the machine arm, both sides of the machine head are respectively provided with sliding seats; the two sliding blocks are fixedly arranged on the sliding seats; the two cylinders are respectively and fixedly arranged on the fixed seats of the machine arm; and the lifting board is respectively connected with the cylinder rod ends on the cylinders and the sliding seats. The machine head liftable structure has the beneficial effects that the lifting and the descent of the machine head are implemented; by lifting and descent of the machine head, an emptying space is increased; and fluffy materials such as automobile chair cushions and throw pillows are more convenient to sew.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a liftable structure of the machine head in the sewing machine.
