A limiting block 7 is provided on the rotating pin 4 to abut against and limit the limiting boss 6. The end cap body 1 has a through hole 8 for the rotating pin 4 to extend out.

[0031] The installation process of the blade of this utility model is as follows: Figure 1-4 As shown, a frame is formed by two vertical frames and two horizontal frames. The end cap of this utility model is inserted into the blade body to form a blade. The rotating pin 4 is pressed inward to compress the spring 5 until the rotating pin 4 is completely retracted into the through hole 8. Then the blade is inserted between the two vertical frames. After the blade is installed in place, the rotating pin 4 extends out of the through hole 8 and is inserted into the mounting hole of the vertical frame under the action of the spring force of the spring 5, thus completing the installation of the blade.

[0032] When the blade body is damaged and needs to be replaced, insert a knife between the end cap and the vertical frame, and cut the rotating pin 4 with the knife to remove the blade. Then install the new blade according to the above installation method. The replaced blade can still be used after replacing the blade body and rotating pin 4.

[0033] The rotating pin 4 of this invention is slidably mounted inside the mounting post 2 of the end cap body 1, and is reset by the spring 5. This allows the frame to be installed first, and then the blades to be installed one by one, without having to align all the rotating pins 4 at once, which is convenient for installation. At the same time, when the blade needs to be replaced, only the blade to be replaced needs to be removed and the new blade is installed, making blade replacement convenient. In addition, the plug 3 is detachably connected to the mounting post 2. After removing the plug 3, a new rotating pin 4 can be replaced, reusing the end cap body 1, the plug 3, and the spring 5, effectively saving replacement costs.
