The mounting block 43 is connected to the side wall of the groove of the stopper 42 through the spring 41.

[0023] The mounting frame 3 is used to install switches and other components connected to cables. The mounting frame 3 is provided with threaded holes to facilitate users to disassemble and install components connected to cables. The top surface of the mounting frame 3 is provided with a groove that is connected to the side wall opening of the mounting frame 3 and covers the side wall opening of the mounting frame 3, ensuring the stability of the components connected to the cables after being installed on the mounting frame 3. The mounting groove 5 is used to store cables to prevent the cables inside the device from being entangled with each other, which may hinder users from removing the cables. The partition plate 12 can divide the mounting groove 5 into multiple groups. The number of groups of the mounting groove 5 is the same as the number of the mounting plates 2. The cables stored in a group of mounting grooves 5 are only connected to components installed on one mounting plate 2. The user can quickly find the cable that needs to be replaced, which is convenient for the user to repair and replace the cable. The fixing mechanism 4 can fix the cable stored in the installation groove 5, ensuring the working effect of the installation groove 5. The user can wind the excess cable on the winding drum 63, and the winding drum 63 is installed on the installation rod 62. The user can first wind the cable on the winding drum 63, and then install the winding drum 63 with the cable wound on the installation rod 62, which is convenient for the user to wind the cable. The reeling groove 61 ensures that the side wall of the installation groove 5 will not hinder the user from installing the reeling drum 63 with the cable wound on the installation rod 62. The position of the reeling groove 61 is convenient for the user to wind the cable;

[0024] The block 42 can fix the cable inside the mounting groove 5 to prevent the cable from escaping from the mounting groove 5 during use. The shape of the side wall of the block 42 is an inclined surface inclined toward the center of the end faces where the two block blocks 42 contact each other, ensuring that the user will not be hindered by the block 42 when installing the cable into the mounting groove 5 or removing the cable from the mounting groove 5, which is convenient for the user to install and remove the cable. The mounting block 43 ensures the stability of the block 42 during movement. The shape of the groove in which the block 42 is installed ensures that the movement of the block 42 will not be hindered by the mounting block 43. The spring 41 ensures that the block 42 can quickly return to its original position after moving, thereby ensuring the working effect of the block 42.

[0025] Specifically, a support rod penetrating the mounting block 43 is disposed on the groove of the stopper 42 , and the spring 41 is installed at the outer side of the support rod in the groove of the stopper 42 .

[0026] The support rod arranged on the groove of the stopper 42 ensures the stability of the stopper 42 during movement. The installation position of the spring 41 ensures that the spring 41 will not deviate during compression, ensures the stability of the connection between the spring 41, the stopper 42 and the mounting block 43, and ensures the working effect of the spring 41.

[0027] Specifically, the tip of the stopper 42 is in an arc shape.

[0028] The pointed shape of the stopper 42 reduces the damage to the side wall of the cable when the cable pushes the stopper 42, thereby extending the service life of the cable.

[0029] Specifically, a breathable layer 51 is provided on the inner wall of the installation groove 5 , and a plurality of through holes are opened on the side wall of the installation groove 5 .

[0030] The breathable layer 51 ensures the breathability of the installation groove 5, preventing the heat generated by the cable during use from being unable to be quickly dissipated, which would affect the service life of the cable. The side wall grooves of the installation groove 5 improve the breathability of the installation groove 5 and the heat dissipation effect of the cable. The breathable layer 51 also improves the friction between the installation groove 5 and the cable, ensuring the stability of the cable after being installed in the installation groove 5.

[0031] Specifically, a protrusion is provided on the side wall of the mounting rod 62, a groove matching with the protrusion on the side wall of the mounting rod 62 is provided on the inner wall of the winding cylinder 63, a threaded handle 64 is rotatably mounted on the winding cylinder 63, and a threaded hole matching with the threaded handle 64 is provided on the mounting rod 62.

[0032] The cooperation between the side wall protrusion of the mounting rod 62 and the inner wall groove of the winding cylinder 63 ensures the stability of the winding cylinder 63 after it is installed on the mounting rod 62, and prevents the winding cylinder 63 from rotating during the use of the device, which may affect the stability of the cable. The cooperation between the threaded handle 64 and the threaded hole on the mounting rod 62 can fix the winding cylinder 63 on the mounting rod 62, and prevents the winding cylinder 63 from detaching from the mounting rod 62 when the user moves the cable, which may affect the stability of the cable after it is installed on the mounting groove 5. The threaded handle 64 is rotatably installed on the winding cylinder 63, which is convenient for the user to fix the winding cylinder 63 to the mounting rod 62.

[0033] Specifically, both ends of the side wall of the winding cylinder 63 are provided with annular protrusions.

[0034] The annular protrusion of the winding drum 63 can fix the cable wound on the winding drum 63 to prevent the cable from detaching from the winding drum 63 when the user moves the winding drum 63. The side wall protrusion of the winding drum 63 can also prevent the cable from contacting the threaded handle 64, causing the cable wound on the winding drum 63 to affect the user's rotation of the threaded handle 64, resulting in the user's efficiency in installing the winding drum 63 on the mounting rod 62 being affected.

[0035] Specifically, a certain distance is left between the mounting plate 2 and the partition plate 12 .

[0036] The space between the mounting plate 2 and the partition plate 12 facilitates the user to connect the cables to the components mounted on the mounting frame 3 .
