The invention discloses a cavel removing device used for a goat. The cavel removing device comprises a processing room and a cavel removing mechanism, wherein two supporting arms, which are oppositely arranged, are separately arranged on two side walls of the processing room; springs are arranged in the supporting arms; clamping arms are arranged on the springs; a supporting table is further arranged on the inner wall of the processing room; a positioning table is detachably connected to the supporting table; the cavel removing mechanism comprises an iron wire, a cavel sleeve and soldering iron; two ends of the iron wire are separately connected with the processing room and the cavel sleeve; a through hole is formed in the top of the cavel sleeve; the soldering iron comprises a soldering iron rod and a soldering iron head; a first through slot is formed in the soldering iron rod; a sandwich layer is arranged between the first through slot and the soldering iron rod; a heating wire connected with a power supply is arranged in the sandwich layer; raised grains are arranged on the top of the soldering iron head; a second through slot is formed in the soldering iron head; and an iron sealing cover is detachably connected to the second through slot. The cavel removing device solves the problem that the cavel removing effect is relatively poor as the goat is not located well and shakes, and also solves the problem that the population position of the goat is reduced after the cravel of the goat is removed.
