When the limit block 201f moves, the clamping plate 201h can be driven to move, and the card frame 201i can be moved through the clamping plate 201h, so that the card frame 201i can fix the data cable, thereby ensuring that the data cable will not loosen.

[0044] Specifically, the fixing member 202 includes a limiting plate 202a and a positioning block 202b. The limiting plate 202a is fixed to one side of the fixing plate 201b. A positioning hole T is formed on the limiting plate 202a. The positioning block 202b is fixed in the positioning hole T.

[0045] There are three limiting plates 202a, all fixed on one side of the fixed plate 201b, for limiting the position of the positioning block 202b.

[0046] Reference Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0047] Specifically, the fixing member 202 further includes a connecting rod 202c and a pulling plate 202d. The connecting rod 202c is fixed to one side of the positioning block 202b, and the pulling plate 202d is fixed to one side of the connecting rod 202c.

[0048] The connecting rod 202c is used to drive the positioning block 202b to move, so that the positioning block 202b can be released from the clamping position with the positioning hole T. The pulling plate 202d is used to pull the connecting rod 202c, so that the positioning block 202b can be driven to move by the connecting rod 202c.

[0049] Specifically, the fixing member 202 also includes a support block 202e, a pressure plate 202f and a compression spring 202g, the support block 202e is fixed to one side of the turntable 201e, the pressure plate 202f is fixed to the surface of the connecting rod 202c, and the compression spring 202g is fixed to one side of the pressure plate 202f.

[0050] The support block 202e is used to ensure that the connecting rod 202c will not deviate when moving, and the pressure plate 202f is used to limit the position of the compression spring 202g. When the connecting rod 202c is pulled outward, the pressure plate 202f can squeeze the compression spring 202g, so that the connecting rod 202c can drive the positioning block 202b to move. The current compression spring 202g is in a released state and is used to limit the position of the positioning block 202b, so that the positioning block 202b is clamped and fixed in the positioning hole T.

[0051] Specifically, the fixing part 202 also includes a positioning plate 202h, a protective cover 202i, a connecting plate 202j and a positioning column 202k. The positioning plate 202g is fixed to the surface of the connecting rod 202c, the protective cover 202h is fixed to the surface of the positioning plate 202g, the connecting plate 202i is fixed to the surface of the protective cover 202h, the positioning column 202j is fixed to one side of the connecting plate 202i, and the positioning column 202j and the turntable 201e are fixed to each other.

[0052] The positioning plate 202h is used to fix the position of the compression spring 202g. When the compression spring 202g is squeezed, the positioning plate 202h can limit the compression spring 202g so that the compression spring 202g will not move, thereby ensuring that the compression spring 202g is evenly stressed. The protective cover 202i is used to protect the pressure plate 202f and the compression spring 202g. The pressure plate 202f can slide in the protective cover 202i to ensure that the pressure plate 202f and the compression spring 202g are not affected by external forces and are not in normal use. The connecting plate 202j is used to fix the position of the positioning column 202k. The positioning column 202k fixes the position of the protective cover 202i through the connecting plate 202j to ensure that the pull plate 202d will not deviate when pulling the connecting rod 202c, and to ensure that the positioning block 202b can be snap-fitted and fixed in the positioning hole T to ensure the position of the limitable turntable 201e.

[0053] When the data line needs to be installed and fixed during use, the turntable 201e is first rotated, and the turntable 201e is used to adjust the data interface to adapt to the data line and ensure that the data line can be installed and fixed in the data interface. When the turntable 201e rotates, the moving rod 201c is driven to move in the limit frame 201d, and the movement of the moving rod 201c drives the limit block 201f to move. When the limit block 201f moves, the clamping plate 201h is moved, and the clamping frame 201i is driven to move by the clamping plate 201h, so that the clamping frame 201i can be fixed. The frame 201i is expanded or contracted to adapt to data cables of different sizes, ensuring that the data cables can be snapped and fixed in the data interface. After ensuring that the data cables and the data interface are installed and fixed to each other, the pulling of the pull plate 202d is cancelled, so that the compression spring 202g releases the pressure, thereby driving the pressure plate 202f to drive the connecting rod 202c to move inward, ensuring that the positioning block 202b can be snapped and fixed in the positioning hole T, thereby ensuring the position of the limitable turntable 201e, ensuring the fixity of the data interface, and preventing the data cable from loosening when the counter device is in use.
