As preferably, the described rocking bar and the traveling nut pin bonded assembly other end are " L " shape to a lateral bending song.Rocking bar is made crooked " L " shape, make a rocking bar play the effect of two bars, simplified structure reduces manufacturing cost.
As preferably, be provided with adapter shaft between the bight of described " L " shape rocking bar and brake collar, the two ends of adapter shaft are hinged with bight and brake collar respectively.Can make rocking bar when fulcrum rotates, can obtain displacement like this.
As preferably, described anchor fitting comprises fixed arm and rocker bracket, and an end of fixed arm is captiveed joint with the captive nut pin on being threaded in screw rod, and the other end is captiveed joint with an end of rocker bracket, and the other end and the rocking bar of rocker bracket are hinged.Fixed arm is captiveed joint with the captive nut pin, makes the rotation of screw rod change the displacement of rocking bar drive brake collar into.
As preferably, contacted of described rocker bracket and fixed arm are arc surface, and rocker bracket and fixed arm are welded to connect.Make rocker bracket can obtain stronger bed knife like this.
As preferably, be threaded with the captive nut pin the last outside thread of part and be threaded with the captive nut pin and be provided with relief groove between following screw thread partly of described screw rod.Make things convenient for the processing of two sections opposite screw threads of screw spiral direction.
As preferably, described brake collar comprises fixed end brake collar and movable end brake collar, and is hinged by articulation piece between fixed end brake collar and movable end brake collar.Make things convenient for brake collar when braking or unclamping, to be easy to generate anchor ear, open deformation, reduce operating personnel's labour intensity.
As preferably, described fixed end brake collar is fixedly connected on the otic placode, and otic placode is provided with through hole, and adapter shaft passes from through hole.
The beneficial effects of the utility model are: the outside thread of screw rod is divided into the opposite two sections screw thread of hand of spiral, change simple rotatablely moving between original screw rod and anchor fitting between screw rod and anchor fitting screw thread pair motion, make screw rod itself can produce displacement when rotated, it is fast that drg peculiar to vessel so just can obtain retro-speed, high efficiency, simple in structure, low cost of manufacture, long service life.
