Food extruder

Abstract

A food extruder has a body, a holder, an extruding rod, a pressing plate and a driving device. The holder is attached to the body and has a rear plate, a supporting frame and a front plate. The rear plate is attached to the body. The supporting frame has a U-shaped cross section and is connected to the rear plate. The front plate is connected to the supporting frame and has an extruding hole defined through the front plate. The extruding rod is slidable and extends through the body and into the holder and has a first end extending into the holder. The pressing plate is attached to the first end of the extending rod and is held inside the holder. The driving device is mounted on the body to drive the extruding rod relative to the body.

1 . A food extruder comprising: 
 a hollow body having a handle extending from the body;    a holder attached to the body and having 
 a rear plate attached to the body;  
 a supporting frame with a U-shaped cross section connected to the rear plate; and  
 a front plate connected to the supporting frame and having an extruding hole defined through it;  
   an extruding rod slidably extending through the body and into the holder and having a first end extending into the holder and a second end extending out of the opposite end of the body;    a pressing plate attached to the first end of the extruding rod and held inside the holder; and    a driving device mounted inside the body to drive the extruding rod relative to the body.    
     
     
         2 . The food extruder as claimed in  claim 1 , wherein the driving device comprises 
 a driving plate mounted inside the body around the extruding rod at an inclined angle and engaging with the extruding rod;    a trigger pivotally attached to the body and having an inner end held inside the body and provided with a pin abutting the driving plate and an outer end extending out of the body;    a resilient member mounted inside the body around the extruding rod and abutting the driving plate;    a brake mounted inside the body around the extruding rod at an inclined angle, engaging the extruding rod to keep the extruding rod from moving outwards from the body and having an extension extending out of the body; and    a biasing member mounted inside the body around the extruding rod and abutting the brake.    
     
     
         3 . The food extruder as claimed in  claim 2 , wherein the body further has an eye defined through the body.  
     
     
         4 . The food extruder as claimed in  claim 3 , wherein the body has a chamber defined through the body to hold the driving device inside and two side plates attached to two sides of the body to close the chamber.  
     
     
         5 . The food extruder as claimed in  claim 4  further comprising a knob attached to the second end of the extruding rod.  
     
     
         6 . The food extruder as claimed in  claim 2 , wherein the body has a chamber defined through the body to hold the driving device inside and two side plates attached to two sides of the body to close the chamber.  
     
     
         7 . The food extruder as claimed in  claim 6  further comprising a knob attached to the second end of the extruding rod.  
     
     
         8 . The food extruder as claimed in  claim 2  further comprising a knob attached to the second end of the extruding rod.  
     
     
         9 . The food extruder as claimed in  claim 1 , wherein the body further has an eye defined through the body.  
     
     
         10 . The food extruder as claimed in  claim 9 , wherein the body has a chamber defined through the body to hold the driving device inside and two side plates attached to two sides of the body to close the chamber.  
     
     
         11 . The food extruder as claimed in  claim 10  further comprising a knob attached to the second end of the extruding rod.  
     
     
         12 . The food extruder as claimed in  claim 9  further comprising a knob attached to the second end of the extruding rod.  
     
     
         13 . The food extruder as claimed in  claim 1 , wherein the body has a chamber defined through the body to hold the driving device inside and two side plates attached to two sides of the body to close the chamber.  
     
     
         14 . The food extruder as claimed in  claim 13  further comprising a knob attached to the second end of the extruding rod.  
     
     
         15 . The food extruder as claimed in  claim 1  further comprising a knob attached to the second end of the extruding rod.
