FIELD OF THE INVENTION [0001] This is a Continuation-In-Part application of applicant's former patent application with application Ser. No. 10/792,700, filed Mar. 05, 2004. BACKGROUND OF THE INVENTION [0002] A conventional positioning rack for mounting electrothermal straps 3 used in heating fan, for example is shown in FIGS. 1-3 and comprises a fixing bracket 1 having a base 102 and a plurality of support arms 104 extend from the base 102. A plurality of insulating members 2 each are mounted on a respective one of the support arms 104 of the fixing bracket 1 and each have a side formed with a plurality of separation portions 204, and a plurality of positioning recesses 202 are located between the separation portions 204 for positioning electrothermal straps 3. [0003] Each of the insulating members 2 is fixed on a respective one of the support arms 104 of the fixing bracket 1 by a plurality of rivets with manual aid of a special tool. However, it is difficult to rivet the insulating members 2 by riveting tools because the gap between the support arms 104 are limited, so that the tools easily touches and collides the insulating members 2 during the riveting process, thereby easily wearing or breaking the insulating members 2. In addition, the insulating members 2 are fixed the support arms 104 of the fixing bracket 1 and only limited space allows tools to access the rivets, so that when either one of the insulating members 2 is worn out or broken, it is necessary to replace the whole positioning rack, thereby wasting the resource, and thereby increasing the costs. SUMMARY OF THE INVENTION [0004] The primary objective of the present invention is to provide a positioning rack for mounting thin-type electrothermal straps for an electric appliance, wherein the blade plates can be easily and conveniently connected to and removed from the support arms without needing aid of a tool. [0005] In accordance with the present invention, there is provided a positioning rack which comprises a main frame having a tubular base and a plurality of support arms extend radially from the tubular base. Two locking members extend from one of two opposite surfaces of each support arm and each locking member has a locking post and a catch block which is connected to a distal end of the locking post corresponding thereto. The locking post is connected to the surface of the support arm. [0006] A plurality of blade plates each have a plurality of hook-shaped separation portions extend from each of two sides thereof and a plurality of positioning recesses are located between the separation portions. Two guide slots and two locking grooves are defined through each of the blade plates. The locking grooves are respectively communicate with the two guide slots. The guide slots each are sized to allow the catch block to pass therethrough and a width of each locking groove is sized to receive the locking post and smaller than a width of each catch block so that the blade plate is not disengaged from the support arm by the catch block. Each of the blade plates is partially clamped between the surface of each support arm and the catch block. [0007] In accordance with another embodiment of the present invention, wherein a connection tube is connected between two tubular bases of two main frames so that the two main frames can be connected with each other. [0008] Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0009] FIG. 1 is a partially perspective view of a fixing bracket of a conventional positioning rack in accordance with the prior art; [0010] FIG. 2 is a plan view of an insulating member of the conventional positioning rack in accordance with the prior art; [0011] FIG. 3 is a plan view of the conventional positioning rack in accordance with the prior art; [0012] FIG. 4 is a partially exploded perspective view of a positioning rack in accordance with the preferred embodiment of the present invention; [0013] FIG. 5 is a plan view of a blade plate of the positioning rack in accordance with the preferred embodiment of the present invention; [0014] FIG. 6 is a plan cross-sectional view of a locking member of the positioning rack in accordance with the preferred embodiment of the present invention; [0015] FIG. 7 shows that the electrothermo straps are positioned on the blade plates of the positioning rack in accordance with the preferred embodiment of the present invention; [0016] FIG. 8 shows the blade plate is to be engaged with the locking member on the support arm; [0017] FIG. 9 shows that the blade plate is pivoted an angle to disengage the electrothermo straps from the positioning recesses of the blade plate; [0018] FIG. 10 is an exploded view of another embodiment of the positioning rack of the present invention; and [0019] FIG. 11 shows the connection between the two tubular bases and the connection tube between the two positioning racks of the present invention.
