Handheld Tool for Detaching and Attaching Agricultural Chain Link

Abstract

The present invention relates to an agricultural chain detacher device designed for detaching or attaching chain links in an agricultural chain. The device features a base with a pair of adjustable clamps to securely hold chains of varying sizes. A vertical wall extends from the base to support a chain link in a vertical orientation. The device includes a screw mechanism with a die hand crank to enable linear movement of a die to interact with the chain link for removal or attachment of the chain link. A center stopper on the base maintains a minimum gap between the clamps for smooth movement of the chain. For attaching a new link, a link connection die is used for fastening flat edge of the new link with curved edge of another link. For removing a link from the chain, a link removing die is used for detaching the link.

What is claimed is: 
     
         1 . An agricultural square chain detacher device comprising:
 a base;   a first clamp and a second clamp positioned on the base, the first clamp and the second clamp configured to maintain a gap therebetween for holding a chain;   a vertical wall extending transversally from a lateral edge of the base, wherein the vertical wall supports a chain link in a vertical position;   a first rotatable bolt and a second rotatable bolt coupled to the first clamp and to the second clamp; and   a handle connected to the base.   
     
     
         2 . The agricultural square chain detacher device of  claim 1  further comprised of a stopper. 
     
     
         3 . The agricultural square chain detacher device of  claim 1 , wherein the handle is comprised of a telescopic handle. 
     
     
         4 . The agricultural square chain detacher device of  claim 1  further comprised of a die hand crank connected to the base. 
     
     
         5 . The agricultural square chain detacher device of  claim 4 , wherein the die hand crank is used to move a screw along the base. 
     
     
         6 . The agricultural square chain detacher device of  claim 5 , wherein the screw engages a square link remover die. 
     
     
         7 . The agricultural square chain detacher device of  claim 5 , wherein the screw engages a chain connecting die. 
     
     
         8 . The agricultural square chain detacher device of  claim 1 , wherein the first clamp and the second clamp are symmetrical. 
     
     
         9 . An agricultural square chain detacher device comprising:
 a base;   a pair of opposing clamps comprised of a first clamp and a second clamp mounted on the base, the pair of opposing clamps being adjustable to hold an agricultural chain;   a stopper positioned on the base to maintain a minimum gap between the first clamp and the second clamp;   a screw movable along the base;   a die hand crank operatively connected to the screw for linear movement of the screw; and   a remover die or chain connecting die attachable to the screw.   
     
     
         10 . The agricultural square chain detacher device of  claim 9 , wherein the first clamp and the second clamp are symmetrical. 
     
     
         11 . The agricultural square chain detacher device of  claim 9 , wherein the base is comprised of a telescopic handle. 
     
     
         12 . The agricultural square chain detacher device of  claim 9 , wherein the stopper is positioned between the clamps. 
     
     
         13 . The agricultural square chain detacher device of  claim 9 , wherein the link remover die is comprised of a groove. 
     
     
         14 . An agricultural square chain detacher device comprising:
 a base;   a pair of adjustable clamps mounted on the base, the clamps comprised of a first adjustable clamp and a second adjustable clamp configured to secure an agricultural chain between them;   a screw operatively connected to the base, the screw being movable along a linear path;   a die hand crank operatively connected to the screw for moving the screw along the base;   a die, wherein the die is configured to engage a chain link for detaching or attaching the link to the chain; and   a handle, wherein rotation of the die hand crank moves the screw to manipulate the chain link.   
     
     
         15 . The agricultural square chain detacher device of  claim 14  further comprised of a first pair of bolts coupled to the first adjustable clamp and a second pair of bolts coupled to the second adjustable clamp. 
     
     
         16 . The agricultural square chain detacher device of  claim 14 , wherein the die is comprised of a groove. 
     
     
         17 . The agricultural square chain detacher device of  claim 14 , wherein the screw is connected to the base. 
     
     
         18 . The agricultural square chain detacher device of  claim 17 , wherein the screw is connected to the base via a crank holding aperture. 
     
     
         19 . The agricultural square chain detacher device of  claim 14 , wherein the die is comprised of a curved end. 
     
     
         20 . The agricultural square chain detacher device of  claim 14 , wherein the die is comprised of a square link remover die.
