Further, the invention also discloses two kinds of preferred tooth bars and to slide spacing formation,

The first structure is, it is rectangular sleeve with hollow cavity that described tooth bar slides spacing, is sheathed on outside push rod.

The second structure is, described tooth bar slip is spacing comprises the interlock part be fixed on outside push rod, and is fixed on the targeting part on tooth bar top, and described interlock part exists when push rod slides the face that partly overlaps with targeting part, and faying surface laminating coupling.

First kind of way is the rectangular sleeve be sheathed on outside push rod by, after this rectangular sleeve is fixing, form the walking cavity of a push rod, thus forms a guide effect to the walking of push rod.

The second way, be the part cooperatively interacted by two, utilize the interlock part with smooth lateral surface be fixed on push rod, coordinate with the targeting part with burnishing surface be fixed on tooth bar, when push rod outwards slides, form guide effect by the mating reaction in two faces.

After adopting technical scheme disclosed in this invention, by the effect of movable door handle, drive the push rod in enabling auxiliary unit, utilize the effect of push rod to reach labor-saving effect.
