Steel strapping tool with a pressing strap structure

Abstract

A steel strapping tool with a pressing strap structure is provided. The steel strapping tool includes a base which has a pivot block extending from a front side thereof. A cutting unit is disposed on the base. The cutting unit includes a fixing seat which has an accommodating trough therein, a top engaging rod unit disposed in the accommodating trough, a cutting assembly having one end coupled to the top engaging rod unit and received in the accommodating trough. The cutting assembly includes a cutting body and a connecting member which extends frontward from one side of the cutting body and passes through the fixing seat. The connecting member is pivotally connected with the pivot block of the base. Between the cutting body and the base defines an included angle. Thereby, the front end of the cutting body holds against a steel strap which is inserted in the steel strapping tool, and then the cutting body is to press the steel strap entirely so as to achieve a firm pressing effect.

1 . A steel strapping tool with a pressing strap structure, the steel strapping tool comprising a base and a cutting unit disposed on the base, the cutting unit comprising a fixing seat which has an accommodating trough therein, a top engaging rod unit disposed in the accommodating trough, a cutting assembly having one end coupled to the top engaging rod unit and received in the accommodating trough, and characterized by:
 the base including a pivot block extending from a front side thereof, the cutting assembly including a cutting body and a connecting member which extends frontward from one side of the cutting body and passes through the fixing seat, the connecting member being pivotally connected with the pivot block of the base, between the cutting body and the base defining an included angle.   
   
   
       2 . The steel strapping tool with a pressing strap structure as claimed in  claim 1 , wherein the connecting member has a free end provided with a pair of first pivot ears which extend downward from the free end, the pair of first pivot ears and the pivot block being connected via a first pivot shaft. 
   
   
       3 . The steel strapping tool with a pressing strap structure as claimed in  claim 1 , wherein the top engaging rod unit is pivotally connected to the fixing seat, the top engaging rod unit including a rod and a linking plate, the rod having a front end formed with a protruding engagement edge and an eccentric first pivot hole, an engaging block extending from one side of the first pivot hole, the linking plate being located beside the first pivot hole and driven by the engaging block, the linking plate having an engaging hole at an upper portion thereof and a second pivot hole at a lower portion thereof, the engaging hole being fitted on the engaging block, a shaft inserting through the first pivot hole and the engaging hole to be pivotally connected to the fixing seat, the cutting body including a pair of second pivot ears thereon, a roller between the pair of second pivot ears, and a second pivot shaft inserting through the pair of second pivot ears, the roller, and the second pivot hole of the linking plate, the protruding engagement edge leaning against the roller. 
   
   
       4 . The steel strapping tool with a pressing strap structure as claimed in  claim 1 , wherein the fixing seat has a penetrating trough at a front lower end thereof, the connecting member passing through the penetrating trough to be pivotally connected to the pivot block.
