[0044] When the moving rod 201h moves, it can drive the pressure plate 201j to move. The movement of the pressure plate 201j can apply a squeezing force to the second spring 201i. By moving the moving rod 201h, the push block 201g can be driven to separate from the two fixed blocks 201d. At this time, the insertion rod 201c can be moved to the bottom of the lower fastening plate 201b, and then the moving rod 201h can be released. The rebound force of the second spring 201i can drive the push block 201g to squeeze the two fixed blocks 201d, so that the two fixed blocks 201d are in contact with the bottom of the lower fastening plate 201b.

[0045] Specifically, the fastener 202 includes a moving frame 202 a , which is sleeved on the outside of the upper shell 101 , and the moving frame 202 a is movably connected to the upper shell 101 .

[0046] The moving frame 202a is fixed on the top of the moving rod 201h. Moving the moving frame 202a will drive the moving rod 201h to move. The movement of the moving rod 201h can drive the push block 201g to separate from the two fixed blocks 201d. At this time, the insertion rod 201c can be moved to the bottom of the lower fastening plate 201b.

[0047] Example 3

[0048] Reference Figure 1 to Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the fastener 202 also includes a locking rod 202b, a support sleeve 202c and a support plate 202d.

[0050] When the movable frame 202a is moved, the support sleeve 202c can be driven to move. When the support sleeve 202c moves, it will move on the locking rod 202b. After the movable frame 202a is moved to the specified position, the movable frame 202a can be limited by limiting the support sleeve 202c, so that the installation of the shell can be completed. The support plate 202d is fixed to one side of the upper shell 101. The support sleeve 202c can be supported by the setting of the support plate 202d to prevent the support sleeve 202c from being offset.

[0051] Specifically, the fastener 202 further includes a fastening bolt 202e and a turntable 202f. The fastening bolt 202e is inserted into one side of the support sleeve 202c. The fastening bolt 202e and the support sleeve 202c are threadedly connected. The turntable 202f is fixed to one end of the fastening bolt 202e.

[0052] When it is necessary to limit the support sleeve 202c, the fastening bolt 202e can be moved on the support sleeve 202c by rotating the fastening bolt 202e. By moving the fastening bolt 202e to one side of the locking rod 202b, a friction plate is provided on one side of the locking rod 202b to increase friction and prevent the fastening bolt 202e from falling off. By moving the fastening bolt 202e to one side of the locking rod 202b, the movable frame 202a can be limited, thereby preventing the installation of the shell from loosening. The fastening bolt 202e can be driven to rotate by rotating the turntable 202f. A rotating block is provided on one side of the turntable 202f. When there is no tool, the user can also use force to rotate the turntable 202f to complete the fixation. Fastening bolts 202e are respectively provided on both sides of the upper shell 101. Therefore, only two fastening bolts 202e need to be fixed to complete the installation of the shell using all the mounting holes.

[0053] Specifically, the fastener 202 also includes a positioning rod 202g, a positioning sleeve 202h and a positioning block 202i. The positioning rod 202g is fixed to the top of the movable frame 202a, the positioning sleeve 202h is sleeved on the outside of the positioning rod 202g, the positioning sleeve 202h and the positioning rod 202g are movably connected, and the positioning block 202i is fixed to the top of the positioning sleeve 202h.

[0054] When moving, the moving frame 202a can drive the positioning sleeve 202h to move on the positioning rod 202g, thereby supporting the moving frame 202a to prevent the moving frame 202a from shifting when moving. The positioning block 202i is fixed to one side of the upper shell 101, and the positioning block 202i is used to support the positioning sleeve 202h to prevent the positioning sleeve 202h from shifting.

[0055] When in use, when it is necessary to fix the upper shell 101 and the lower shell 102 together, first move the moving frame 202a, and the moving frame 202a can drive the moving rod 201h to move. When the moving rod 201h moves, it can drive the pressure plate 201j to move. The movement of the pressure plate 201j can apply a squeezing force to the second spring 201i. When the moving rod 201h moves, it can drive the push block 201g to move, so that the push block 201g is separated from the two fixed blocks 201d, and then the rebound force of the first spring 201f can be used to release the push block 201g from the two fixed blocks 201d. To drive the two fixed blocks 201d to retract into the insertion rod 201c, the upper shell 101 can be placed on the top of the lower shell 102. After the upper shell 101 is placed on the top of the lower shell 102, the upper shell 101 will drive the upper fastening plate 201a to contact the lower fastening plate 201b, and then release the movable frame 202a. The rebound force of the second spring 201i can drive the push block 201g to squeeze the two fixed blocks 201d, so that the two fixed blocks 201d are in contact with the bottom of the lower fastening plate 201b, thereby completing the fixation of the shell.

[0056] When the movable frame 202a is moved, the support sleeve 202c can be driven to move. When the support sleeve 202c is moved, it will move on the locking rod 202b. After the movable frame 202a is moved to the specified position, the support sleeve 202c needs to be limited. By rotating the turntable 202f, the rotation of the turntable 202f can drive the fastening bolt 202e to rotate. By rotating the fastening bolt 202e, the fastening bolt 202e can move on the support sleeve 202c. By moving the fastening bolt 202e to one side of the locking rod 202b, the movable frame 202a can be limited, thereby preventing the installation of the shell from loosening. Fastening bolts 202e are respectively arranged on both sides of the upper shell 101. Therefore, only two fastening bolts 202e need to be fixed to complete the installation of the shell using all the mounting holes.
