The extension portion 43 is connected in the middle of the mounting portion 41, the closed end 12 of the hanger 1 can protrude to opposite sides of the extension portion 43, and the extension portion 43 is configured to escape the closed end 12 of the hanger 1. In one embodiment, the mounting portion 41 is configured as a block structure, the extending portion 43 is configured as a vertical plate structure, one end of the extending portion 43 is fixedly connected to the middle of the end surface of the mounting portion 41, and two opposite sides of the extending portion 43 face the two fixing rods 220, respectively, to form a narrower "waist" of the hook clip assembly 4. The extending portion 43 is further provided with a notch at one end of the connecting and mounting portion 41, the notch is used for avoiding the hook 1, the closed end of the hook 1 extends into the notch of the extending portion 43 after extending out of the mounting hole 411, and two sides of the closed end 12 of the hook are respectively located on opposite sides of the extending portion 43. When the hook 1 moves to the hanging position 201 of the mounting frame 2, the narrow extending part 43 can pass through the limiting structures 202 on the two sides, and the two sides of the closed end 12 of the hook are blocked by the limiting structures 202 and limited at the hanging position 201.
The fixing portion 42 includes two opposite vertical plates, and the two vertical plates of the fixing portion 42 may be configured into a U-shaped structure. The fixing portion 42 may be provided with a through hole for passing a fixing structure such as a connecting shaft or a screw. Of course, the fixing portion 42 may be provided in other structures for easy installation according to the specific structure of the transmission chain or belt of the moving assembly 3.
The mounting portion 41, the extending portion 43 and the fixing portion 42 of the hook clip assembly 4 may be of a split structure, fixedly connected together by welding, bonding, or the like, or integrally formed. In this embodiment, the hook clip assembly 4 is an integral structure having strong structural strength.
