Fig. 2 is a top view of the high strength sinker assembly of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 2, a high strength sinker assembly includes a sinker mother board 10, a sinker slider 20, and a transpose base 30.

One end face of the letter gram mother board 10 is rotationally fixed with two groups of bearing sets, and each bearing set comprises a plurality of bearings 11.

The letter gram slide plate 20 middle part is equipped with letter gram tooth row 21, and letter gram slide plate 20 is equipped with two exhibition wing-shaped guide rails 22, and two sets of bearing group pass two guide rails 22 respectively, and the bearing group slides in guide rail 22, and the bending range that guide rail 22 is close to letter gram tooth row 21 one side is less than the bending range that guide rail 22 keeps away from letter gram tooth row 21 one side. In other words, the guide rail 22 near the row 21 of the sinker teeth is nearly in a long straight state, and the thrust transmitted by the row 21 of the sinker teeth is converted into transverse power to a great extent, so that only a small part of vertical component force acts on the guide rail 22, the probability of deformation is reduced, and the service life of the sinker assembly is prolonged.
