The hooks 34a', 34b' are located outside the slot 142' to be engaged on the rack 3, thereby fixing the draw-out fixing device 1 on the rack 3.

[0074] The two fixing members 40, 40' can be shaft members. The fixing member 40 penetrates the pivot portion 242, the body 32, the fixing frame 14 and the elastic tenon 30 along the Y-axis direction to arrange the handle 20 and the elastic tenon 30 on the fixing frame 14, so that the handle 20 can rotate around the two fixing members 40, 40' and the pivot portion 242 as the axis. In the present embodiment, the fixing member 40 penetrates the other end of the body 32 of the elastic tenon 30 opposite to the hook 34, and the hook 34 is not fixed and can be tilted up.

[0075] The fixing member 40' penetrates the pivot setting portion 242', the body 32', the fixing frame 14' and the elastic clasp 30' along the Y-axis direction to set the handle 20 and the elastic clasp 30' on the fixing frame 14', so that the handle 20 can rotate about the pivot setting portion 242' as the axis. In the present embodiment, the fixing member 40' penetrates the body 32' of the elastic clasp 30', and is arranged opposite to the other end of the clasp 34', so that the clasp 34' is not fixed and can be tilted up.

[0076] After the structure is explained, the use method of the detachable fixing device 1 is explained. Please refer to Figure 1 and Figure 2 , the exchanger 2 is first installed on the seat body 10 of the detachable fixing device 1. In the present embodiment, when the exchanger 2 is installed on the seat body 10, it can just fit and tightly contact the limiting frame 16 and the fixing plate 18, so that after the fixing hole 180 is penetrated by the screw, the screw can be locked on the exchanger 2 to fix the exchanger 2 on the detachable fixing device 1. Since the two sides of the installation rod 24 and 24' of the handle 20 are of the same structure, and the actions of the two sides are the same when the handle 20 is moved, in the present embodiment, only one side of the installation rod 24 is explained.

[0077] As shown in Figure 2 , the handle 20 is located in a storage position, at this time the grip rod 22 is adjacent to the fixing plate 18. The protrusion 244 is separated from the body 32 of the elastic clasp 30. The body 32 contacts the stop portion 146 of the fixing frame 14. In addition, in the Y-axis direction, the clasp 34 can protrude from the stop portion 146 of the fixing frame 14.

[0078] Then the detachable fixing device 1 is installed to the rack 3. The handle 20 is rotated from the Figure 2 storage position to the Figure 4 and Figure 5 installation position. As shown in Figure 4 and Figure 5 , the handle 20 is moved downward, so that the installation plate 240 rotates counterclockwise about the pivot setting portion 242. When the installation plate 240 rotates, the protrusion 224 on the installation plate 240 also moves. When the protrusion 224 moves upward, it presses the body 32 of the elastic clasp 30, so that the body 32 is tilted up and the clasp 34 is also tilted up in the direction of the center of the body 10.

[0079] As shown in Figure 4As shown, the handle 20 is in an installation position, at which time the grip 22 is away from the fixed plate 18. The protrusion 244 abuts against the body 32 of the elastic clasp 30, and separates the body 32 from the stop portion 146 of the fixed frame 14. In addition, the distance between the top end of the clasp 34 and the stop portion 146 of the fixed frame 14 when the handle 20 is in a storage position is less than the distance between the top end of the clasp 34 and the stop portion 146 of the fixed frame 14 when the handle 20 is in the installation position.

[0080] Please refer to Figure 6 After the extractable fixing device 1 and the exchanger 2 are placed into the rack 3, the clasp 34 is located in the rack 3 and separated from the clamping groove 4. Then, the handle 20 is lifted towards the fixed plate 18, so that the handle 20 returns to the storage position. The mounting plate 240 rotates clockwise around the pivot portion 242, and the protrusion 244 moves to separate from the elastic clasp 30. The elastic clasp 30 returns to its original position, and the body 32 contacts the stop portion 146 of the fixed frame 14. The clasp 34 passes through the clamping groove 4. In this embodiment, the clasps 34a and 34b can be clamped into the two clamping grooves 4 of the rack 3, so that the extractable fixing device 1 is installed in the rack 3.

[0081] Similarly, when the extractable fixing device 1 is to be taken out of the rack 3, the handle can be turned downwards again, so that the handle 20 is in the installation position. The mounting plate 240 rotates counterclockwise around the pivot portion 242, and the protrusion 244 moves to press the body 32 of the elastic clasp 30 again. The body 32 moves away from the stop portion 146, and the clasps 34a and 34b are separated from the clamping groove 4, so that the extractable fixing device 1 can be taken out of the rack 3.

[0082] In summary, the present application can achieve simple disassembly and exchange of the exchanger, and the handle can be stored when not in use, so that the handle does not protrude from the extractable fixing device, and space can be effectively saved.

[0083] In summary, the present application meets the requirements of the invention patent, and a patent application is submitted in accordance with the law. However, the above is only a preferred embodiment of the present application, and the scope of the present application is not limited to the above embodiment. Any equivalent modification or change made by those skilled in the art in accordance with the spirit of the present application should be covered by the following patent application range.
