Abstract

The utility model provides a can increase leaf of drawing of width, its characterized in that of technical scheme draws leaf, knocker including marker rod, handle, stroke leaf, U -shaped, the marker rod rear end is connected the handle front end and is connected a stroke leaf, and stroke leaf is the middle part and favors the thin structure of limit portion, and the U -shaped is provided with and draws the U -shaped recess that the leaf matches in drawing the leaf, and is fixed with the knocker behind the U -shaped stroke leaf cutting income U -shaped recess, when the user need use narrow stroke of leaf, relieve the knocker and take off the U -shaped and draw the leaf, when the user need use wide stroke of leaf, the U -shaped was drawn and is fixed with the knocker after the U -shaped recess is gone into to the leaf cutting, the power -off no -leakage balance cylinder is advantageous in that. The length and the width of adjustable stroke of leaf of the fan that rows the boat can satisfy the custom and use different specifications to draw the fan that rows the boat of leaf.

Description

A kind of leaf of drawing that can increase width

Technical field

The utility model relates to draws a leaf, specifically a kind of can increase width draw the technical characterictic of leaf, belong to the technical field of the instrument of rowing the boat.

Background technology

Drawing leaf is a part of structure of oar, oar is again the instrument of rowing the boat, the structure of oar is to draw rod rear end connecting handle front end to connect a stroke leaf, is inconvenient to increase but the technical deficiency of this structure is length and the width of drawing leaf, is inconvenient to meet the fan that rows the boat that custom is used different size to draw leaf.

Summary of the invention

In order to overcome the deficiency of existing stroke of leaf technology, the utility model provides a kind of technical characterictic of drawing leaf that can increase width, this kind of leaf of drawing that can increase width, and the fan's capable of regulating of rowing the boat is drawn length and the width of leaf, can meet the leaf of drawing of custom use different size;

For achieving the above object, the utility model, a kind of leaf of drawing that can increase width, technical scheme is characterized in that, comprise draw a bar, handle, draw leaf, U-shaped is drawn leaf, knocker; Described stroke of rod rear end connecting handle front end connects draws leaf, drawing leaf is the thin structure of middle part webbing portion, U-shaped is drawn and in leaf, is provided with and draws the U-shaped groove that leaf matches, U-shaped is drawn leaf and is inserted after U-shaped groove and fix with knocker, when described user need be with narrow stroke of leaf, remove knocker and take off U-shaped and draw leaf, when described user need be with wide stroke of leaf, U-shaped is drawn after leaf insertion U-shaped groove and is fixed with knocker;

The utility model has the advantages that; The fan's capable of regulating of rowing the boat is drawn length and the width of leaf, can meet the fan that rows the boat that custom is used different size to draw leaf.
