Further, described counterbalance comprises balance plate and fixing part, and described fixing part is for being provided with externally threaded tubular structure, and one end of described spring is fixed on described fixing part.
Further, the diameter of described spring is 1.4mm.
Further, the number of turns of described spring is 200-215.
Further, described stationary axle top is provided with flat spindle nose, and described flat spindle nose and described stationary axle are one-body molded setting.
Further, described stationary axle, described flat spindle nose, described in a roll left end socket, described counterbalance be plastic material.
The advantage that the utility model has and good effect are:
1, the utility model structure stability is good, and balance plate and the fixing part of counterbalance are one-body molded, improves the holding strength of whole spring mechanism and balance dynamics relative to the balance plate be movably connected on axostylus axostyle;
2, through described second pin-and-hole, spring mechanism and end casing are fixed by pin, spring mechanism is connected with post stand body more firm, ensure that the useful effect of elastic force and the working life of post stand.
3, the diameter of spring is 1.4mm, and the number of turns is set to 200-215 circle, ensure that the torsion strength be involved in completely by painting canvas in base, and more soft, more laborsaving at the prerequisite lower pulling force that cost compare is low.
