1. A horn fixing device of an ultrasonic welding device for a secondary battery tab, the horn fixing device comprising:
an amplifier for ultrasonic welding of the secondary battery tab;
a fixing block member having an amplifier through hole formed therein and configured to allow the amplifier to be installed therethrough, the fixing block member having a pad insertion space formed at an upper portion of the amplifier through hole, wherein the pad insertion space allows an amplifier compression member to be installed therein;
the amplifier compression member installed in the pad insertion space so as to compress the amplifier placed in the amplifier through hole; and
a setting block member installed on one surface of the fixing block member to adjust an angle of the amplifier,
wherein the setting block member comprises:
a setting block installed on the one surface of the fixing block member to adjust the angle of the amplifier; and
an angle adjustment unit installed in the setting block to adjust the angle of the amplifier passing through the setting block, and
wherein the setting block comprises:
a through hole formed to allow the amplifier to be installed therethrough;
a cutout portion formed to be cut out on an upper portion of the setting block so that the amplifier is press-fitted therein;
a horizontal bolt hole formed at the upper portion of the setting block so that the amplifier is compressed by pressure of the cutout portion; and
an insert hole formed on one lower portion of the setting block and enabling the angle adjustment unit to be installed in the setting block.
