The invention relates to an installing structure of multiple screw-type fuses. Through the arrangement of a line bank, one binding posts of multiple fuse carriers can be all effectively connected in series, wires are not needed, wiring in the installation of the multiple fuses is greatly simplified, and the problem of complex circuits in the later using process is prevented. When some fuse needs to be used, a wiring terminal just needs to be electrically connected with an external wire and then connected with the binding post of the corresponding fuse to be used, so that when the multiple fuses are installed and used at the same time, only the wiring terminal and the corresponding binding post need to be connected according to the wiring mode, and the installing structure is very easy and convenient to use.
