Title: Sewing machine table

Description:
FIELD OF THE INVENTION 
     The present invention relates to a sewing machine table, more particularly, to a sewing machine table in which a sewing machine body and a sewing machine foot pedal are installed. 
     BACKGROUND OF THE INVENTION 
     In general, a sewing machine is a machine used to make or sew clothes using various fabrics and thread with a needle. The sewing machine can make clothes within a short time beyond the time limitation of human hands. 
     A sewing machine table is composed of a top plate on which a sewing machine and fabric are placed and legs supporting the top plate to perform a sewing operation. 
     More specifically, the sewing machine table is manufactured by combining a flat top plate having a predetermined area with a long shape and legs having a predetermined length on a bottom surface of the top plate. 
     However, such a sewing machine table with legs having predetermined length has a problem in that it is difficult for some operator to work if the body size of an operator does not fit with the table dimensions. 
     In addition, since a foot pedal of the sewing machine is not fixed, when the operator uses the foot pedal, the foot pedal is pushed forward by the operator&#39;s foot. Accordingly, the operator cannot properly step on the foot pedal or uses the foot pedal with difficulties, and thus, work efficiency decreases.

     Operating cylinders  121   a  of the height adjustment support  121  are coupled to both bottom ends of the top plate  111  to adjust the height of the top plate  111 . A piston rod  121   b  of the height adjustment support  121  is provided at a bottom end of the operating cylinder  121   a.    
     A lower support  123  of the height adjustment support  121  is coupled to a bottom end of the piston rod  121   b.    
     Although not shown, the height adjustment support  121  is operated by a separate motor and a switch. 
     An upper connecting plate  122  is coupled between the operating cylinders  121   a.    
     A first fixing protrusion  122   b  drawn out by elasticity is formed on a front surface of the upper connecting plate  122 . 
     In this case, it is desired that the first fixing protrusion  122   b  is formed of magnetic material. 
     In addition, a first lower connecting plate  124  is coupled between the lower supports  123 . 
     An operating foot pedal of the sewing machine is installed on the first lower connecting plate  124 .
