Sleeve is stated to connect with clutch.
The principle of this programme is such that first gear and second will be rotated through by the clutch being pressed in shaft
Gear passes to mandrel, and mandrel is equipped with the turntable around steel wire, by steel wire encircling on turntable, to increase whole on turntable
Diameter, rotate roller on lever along axis both clockwise direction, sliding slot be equipped on lever, so that being slidably connected to fixation
The pin of guide rail and sliding slot moves and sliding block is forced to move up relative to fixed guide rail, when sliding block is just detached from pin, even
It connects in the handle on sleeve under the action of helical spring, starts to be rotated in the clockwise direction, at this moment clutch is disengaged from, machine
Structure stopping movement entering the position of engagement with handle when sliding block is mobile and urges the clutch into when needing to restart work
Bonding station, the lever with roller are located at left side, and contact of the roller with sleeve is drawn on hoisting machinery by steel wire
Weight is realized.
Preferably, it is additionally provided with cam path on the sleeve, pin is equipped in cam path, when handle rotates counterclockwise
When, sleeve moves right, access clutch, and the turntable in mandrel around steel wire is restarted again.
Preferably, it is connected with vertical pillar on the lever, pillar is fixed on the base, and pillar is to prevent lever
Axial movement.
Preferably, the turntable is equipped with the annular groove around steel wire, so that steel wire is gradually surrounded on the ring on turntable
When in connected in star, it is avoided that steel wire slides from turntable, it is ensured that job stability.
