Crochet anti-slip structure

Abstract

A crochet anti-slip structure includes a crochet shaft and an anti-slip sleeve. The crochet shaft is rod-shaped and has a crochet section and a binding section, and at least one arc-shaped convex body having an expanded diameter is disposed at the outer periphery of the binding section. The anti-slip sleeve is made of elastic plastic and has a binding hole configured to be opposite to the binding section for inserting the binding section into the binding hole to achieve an anti-slip effect between the crochet shaft and the anti-slip sleeve as well as an anti-slip effect for a user to grip and use a crochet.

What is claimed is: 
     
         1 . A crochet anti-slip structure, comprising a crochet shaft and an anti-slip sleeve, and the crochet shaft being substantially rod-shaped, and having a crochet section and a binding section integrally formed thereto, a hook portion disposed at an end opposite to the crochet section, and at least one arc-shaped convex body having an expanded diameter and disposed at an outer periphery of the binding section; and
 the anti-slip sleeve having a binding hole formed at a position opposite to the binding section and configured to be corresponsive to the binding section, and the binding hole not penetrating through the anti-slip sleeve, but having an inlet for allowing the binding section of the crochet shaft to be inserted from the inlet into the binding hole, and a tight-fit state being defined between the arc-shaped convex body of the crochet shaft and a contact surface of the binding hole of the anti-slip sleeve.   
     
     
         2 . The crochet anti-slip structure according to  claim 1 , wherein the binding section of the crochet shaft has a neck portion having a reduced diameter relative to the arc-shaped convex body and disposed at a junction with the crochet section, such that the crochet section has an external diameter greater than the external diameter of the neck portion of the binding section, and a vertical braking surface is formed between the crochet section and an adjacent connected surface of the binding section for limiting the depth for the binding section to be inserted into the binding hole. 
     
     
         3 . The crochet anti-slip structure according to  claim 2 , wherein the arc-shaped convex body of the crochet shaft is disposed adjacent to a position of the neck portion opposite to the vertical braking surface. 
     
     
         4 . The crochet anti-slip structure according to  claim 1 , wherein the binding hole of the anti-slip sleeve has an exhaust hole formed at a position opposite to the inlet of the binding hole and communicating with the outside. 
     
     
         5 . The crochet anti-slip structure according to  claim 1 , wherein the anti-slip sleeve has a flat thumb rest disposed on an outer surface thereof. 
     
     
         6 . The crochet anti-slip structure according to  claim 5 , wherein the thumb rest of the anti-slip sleeve is configured to be corresponsive to the arc-shaped convex body of the crochet shaft. 
     
     
         7 . The crochet anti-slip structure according to  claim 6 , wherein the arc-shaped convex body of the crochet shaft has a flat plane configured to be corresponsive to the thumb rest of the anti-slip sleeve, and allowing the thumb rest to be cladded on the outside of the plane for preventing the crochet shaft and the anti-slip sleeve from being deflected with respect to each other.
