The rotating portion 270 has a screw head 2701 exposed on the surface of the rotating handle 25 so that the user can control the rotation of the rotating portion 270 by the screw head 2701. The screw head 2701 is marked with a logo for locking and unlocking for the user to use. The rotating portion 270 is coupled to the ratchet piece 271. Further, the rotating portion 270 can be coupled to the ratchet piece 271 via a bolt 272. When the rotating portion 270 rotates, the ratchet piece 271 is rotated. In this embodiment, the rotating portion 270 can drive the ratchet piece 271 to rotate by 90 degrees. A corresponding position of the inner side wall of the receiving frame 24 is provided with a stopping portion 243, and the ratchet piece 271 is rotatable under the stopping portion 243 for limiting the upward movement of the ratchet piece 271 to prevent the The rotary handle 25 is rotated relative to the receiving frame 24.

When the screw head 2701 is pointed to the locking position, the ratchet piece 271 is located below the stop portion 243, and the stop portion 243 restricts the ratchet piece 271 from moving up and down to prevent the rotating handle 25 from rotating relative to the receiving frame 24. . When the user rotates the screw head 2701 to point from the locked position to the unlocked position, the screw head 2701 drives the rotating portion 270 to rotate, thereby driving the ratchet piece 271 to make the ratchet piece 271 from the stop portion. When the 243 is disengaged, the rotating handle 25 is rotatable relative to the receiving frame 24.

The initial position of the end of the containment bracket 24 is schematically indicated by a dashed line in the figure.

Referring to Figures 2 and 7, the rotary handle 25 is urged to rotate from a first position to a second position, the side wall of the opening 250 being in contact with the base 23 and squeezing the base 23. Since the base 23 is fixed to the casing 21, the base 23 is a fixing member. When the side wall of the opening 250 presses the base 23, the base 23 does not move, the rotating handle 25 receives the force of the base 23, and the rotating handle 25 moves relative to the base 23, thereby pushing the latching device 22 Moving relative to the base 23 in the first direction L1, the upper cover 20 is further horizontally moved relative to the casing 21 in the first direction L1. Since the rotating handle 25 is pivotally connected to the inner side wall of the receiving frame 24, the rotating handle 25 drives the receiving frame 24 to move, thereby driving the latching device 22 to move relative to the base 23 in the first direction L1, and will rotate. The rotational movement of the handle 25 translates into a horizontal movement of the latching device 22. Since the latching device 22 is fixedly mounted on the upper cover 20, the movement of the latching device 22 causes the upper cover 20 to horizontally move relative to the casing 21 in the first direction L1, thereby further converting the rotational motion of the rotating handle 25. For the horizontal movement of the upper cover 20, the upper cover 20 is mounted on the casing 21. The initial position of the end of the containment bracket 24 is schematically indicated by a dashed line in the figure.

At this time, the opening 251 of the rotating handle 25 is engaged with the protruding elastic piece 242, so as shown in FIG. 8, the rotating handle 25 is fixed in the receiving frame 24 to prevent the rotating handle 25 from rotating. The upper cover 20 is fixed to the casing 21. Further, after the rotating handle 25 is rotated to the second position, the rotating portion 270 is controlled to rotate by rotating the screw head 2701 of the locking structure 27 to drive the ratchet piece 271 to rotate under the stop portion 243 to prevent The rotary handle 25 is rotated relative to the recess 240. The initial position of the end of the containment bracket 24 is schematically indicated by a dashed line in the figure. So far, the latching device 22 drives the upper cover 20 to be assembled on the casing 21.

The above process is to assemble the upper cover 20 to the casing 21 by using the latching device 22. The process of detaching the upper cover 20 from the casing 21 is opposite to the above assembling process, except that, as shown in FIG. When the upper cover 20 is detached from the casing 21, the other side wall of the opening 250 reversely presses the base 23 to push the latching device 22 opposite to the first direction L1 with respect to the base 23. The second direction L2 moves while the upper cover 20 is horizontally moved relative to the casing 21 in the second direction L2. Referring to FIGS. 2 and 9 , when the rotating handle 25 fixed in the receiving frame 24 is pulled up, the protruding elastic piece 242 is disengaged from the opening 251, and the protruding elastic piece 242 is lost.
