Positioning rack for thin-type electrothermal straps

Abstract

A positioning rack includes a main frame, and a plurality of blade plates. The main frame includes a base and a plurality of support arms. Each of the blade plates is formed with at least one guide slot having an end formed with a locking groove. Each of the support arms has at least one locking member having a locking post detachably inserted into the locking groove, and a catch block formed on a distal end of the locking post and rested on a surface of a respective blade plate. Thus, each of the blade plates is removed from the respective support arm easily and conveniently without needing aid of a tool, thereby facilitating the user replacing the blade plates.
