The interchangeable self-locked draught part of foregoing pulling-on piece, the draw piece is a thread.
The interchangeable self-locked draught part of foregoing pulling-on piece, the draw piece are movably fixed to shape between horse hook and pull head body
Into elastic switch in.
The interchangeable self-locked draught part of pulling-on piece as described above, is equiped with cap on the pull head body of the pull head；The cap court
Pull head body direction is extended with a lug, and lug is equipped with mounting hole；The pull head body end face is convex to be equipped with left and right lug,
The lateral surface of left and right lug be convexly equipped with it is left and right pick up the ears, left and right lug and left and right pick up the ears to be equipped with concentric holes；Cap is supported
It is left and right pick up the ears on, to form the lateral wall for extending to from cap pull head body end face；Have one between left and right lug for cap
The accommodating gap of lug insertion；One pipe axis is threaded through in mounting hole and concentric holes, and cap is fixed on pull head body.
The interchangeable self-locked draught part of foregoing pulling-on piece, the left and right lug pick up the ears to set higher than left and right, to be formed
One is step-like, and the left and right side walls of cap are interposed on left and right lug, and are supported on left and right pick up the ears.
Above-mentioned technical proposal is beneficial in that：
The present invention is that Patent No. CN201320424015.1 " is drawn disclosed in 2014-02-05 in Chinese patent literature
It is improved on the basis of the interchangeable self-locked draught part of piece ".Long recess is correspondingly provided with two side on cap, and is put with unification
Enter the draw piece in elastic switch, draw piece pulls horse hook and is lifted up horse hook along long recess, elastic switch is opened, to pull down or fill
Enter pulling-on piece, solve pull head after plating oil spout or spray painting, caused by the rotation of horse hook is dumb the problem of pulling-on piece bad dismounting.This
Invention draw piece can use thread, will not stuck horse hook.Moreover draw piece is movably fixed in elastic switch, that is, using
During, after pull head collocation draw piece, it can also solve in the case of no pulling-on piece, can still be unlocked by position part.Filled on pull head
Equipped with pulling-on piece, the beauty of pull head can be further lifted.
Pull head of the present invention reduces the requirement to mould from the improvement of cap structure, and is positioned at drawing by lug thereon
Head body left and right lug between, then by it is sandwiched and support left and right lug and it is left and right pick up the ears on left and right side walls, make cap
Lid is not only easy to assembly and positioning is more accurate.
