Pipe Flaring Device

Abstract

A pipe flaring tool includes a case member, a clamping member, a flaring module, a feeding member and a connecting member. The case member has a first end, a second end, a chamber and a bore at the first end and communicated with the chamber. The clamping member connected to the second end of the case member. The flaring module is received in the chamber, having a shaft and a flaring terminal. The flaring terminal is connected to an end of the shaft and proximal to the clamping member. An opposite end of the shaft is proximal to the bore of the case member to engage a power tool through the bore. A feeding member is received in the chamber. A connecting member is detachably connected to the flaring module to the feeding member, wherein the flaring module and the feeding member are turned and moved together.

What is claimed is: 
     
         1 . A pipe flaring tool, which is driven by a power tool to enlarge a diameter of an end of a pipe, comprising:
 a case member has a first end and a second end, wherein the case member has a chamber therein and a bore at the first end and communicated with the chamber;   a clamping member connected to the second end of the case member for holding the pipe;   a flaring module, which is received in the chamber of the case member, having a shaft and a flaring terminal, wherein the flaring terminal is connected to an end of the shaft and proximal to the clamping member, and an opposite end of the shaft is proximal to the bore of the case member to engage the power tool through the bore;   a feeding member, which is received in the chamber of the case member, to be reciprocated in a limited range; and   a connecting member detachably connecting the flaring module to the feeding member, wherein the flaring module and the feeding member are turned and moved together when the connecting member connects the flaring module to the feeding member, and the flaring module is turned and the feeding member is kept still when the connecting member disconnects the flaring module to the feeding member.   
     
     
         2 . The pipe flaring tool of  claim 1 , wherein the connecting member has a rod and an elastic member; the rod is movably connected to the flaring module, and the elastic member urges the rod toward the feeding member; the feeding member has a hole; the connecting member connects the flaring module to the feeding member by the rod engaging the hole, and the connecting member disconnects the flaring module to the feeding member by the rod disengaging the hole. 
     
     
         3 . The pipe flaring tool of  claim 2 , wherein the rod is provided with a slot; a pin has an end fixed to the flaring module and an end extending to the slot. 
     
     
         4 . The pipe flaring tool of  claim 2 , wherein the rod has an inclined face on an end facing the feeding member. 
     
     
         5 . The pipe flaring tool of  claim 1 , wherein the feeding member is provided with a threaded portion, and the case member is provided with an outer threaded section; both the feeding member and the flaring module are turned and reciprocated when the threaded portion of the feeding member engages the outer threaded section of the case member. 
     
     
         6 . The pipe flaring tool of  claim 5 , wherein the feeding member further is provided with a flat portion next to the threaded portion; both the feeding member and the flaring module are turned only when the threaded portion of the feeding member disengages the outer threaded section of the case member and the flat portion is associated with the outer threaded section. 
     
     
         7 . The pipe flaring tool of  claim 1 , further comprising a spring having opposite ends urging the feeding member and the flaring module. 
     
     
         8 . The pipe flaring tool of  claim 7 , wherein the feeding member has a room, in which the spring is received; the shaft of the flaring module has passes through the room of the feeding member and the spring. 
     
     
         9 . The pipe flaring tool of  claim 7 , wherein the flaring member has a base, on which the connecting member is provided, and the spring urges the feeding member toward the base to make the feeding member touch the base of the flaring member normally. 
     
     
         10 . The pipe flaring tool of  claim 9 , wherein the connecting member separates the feeding member from the base of the flaring member when the connecting member disconnects the feeding member to the flaring member.
