The connecting end pieces 11 are used to connect the circuit, and a connecting block 12 is installed on the side corresponding to the connecting end piece 11. The connecting block 12 is used to connect the connecting end piece 11 and the fuse 32 for circuit connection. A limiting ring 4 is installed on one side of the connecting block 12. The limiting ring 4 will further strengthen the circuit connection stability of the fuse 32, so that the fuse 32 will connect the circuit, so that the circuit forms a loop, thereby ensuring the normal operation of the circuit. When a short circuit or other conditions occur in the circuit, resulting in an abnormal increase in current, the fuse 32 The internal fuse will overheat due to the large amount of current flowing through it, and thus melt, completing the circuit cutting off, ensuring that the equipment will not be damaged by the large flow of current. The active block 13 sliding on one side of the installation shell 1 is used to drive the driven plate 3 to move. A plurality of sorting plates 31 are fixed on one side of the driven plate 3. The sorting plates 31 are used to fix a plurality of fuses 32. The staff can place a plurality of fuses 32 between the sorting plates 31 in advance, and then the staff can slide the active block 13 to the inside of the sorting plate 31 at the bottom, so that the active block 13 can drive the sorting plate 31 to move. At this time, the staff can slide the active block 13, so that the driven plate 3 drives the sorting plate 31 and the fuse 32 to move. When the fuse 32 moves, it will contact the fitting ring 41, and the top of the fitting ring 41 is provided with an inclined block, so that when the fuse 32 applies a vertical downward force to the fitting ring 41, it will drive the fitting ring 41 to move horizontally, until the fuse 32 can slide to the inner side of the limiting ring 4 and the fitting ring 41, at this time, both ends of the fuse 32 will contact the connecting block 12, and be fixed by the constraints of the limiting ring 4 and the fitting ring 41. When the fuse 32 is blown, the staff can slide the active block 13 vertically again, so that the active block 13 drives the driven plate 3, the sorting piece 31 and the fuse 32 to move. At this time, the fuse 32 located at the top will replace the fuse 32 whose internal fuse has been blown and slide to the inside of the limiting ring 4 and the fitting ring 41, so as to facilitate the workers. In order to replace the fuse 32 and improve the circuit recovery speed, when the fuse 32 between the sorting pieces 31 is used to the last one, the staff can replace the fuse 32 between the sorting pieces 31 in advance. At this time, the staff can slide the driven plate 3 horizontally. The fuse 32 located between the limiting ring 4 and the fitting ring 41 is limited by the limiting ring 4, so that the driven plate 3 will only drive the sorting piece 31 to move horizontally. Then the staff can slide the active block 13 out of the inside of the driven plate 3 so that the driven plate 3 can move vertically. Then the staff can slide the driven plate 3 vertically so that the sorting piece 31 is located above the fuse 32 being used, and cancel the engagement between the top protective compartment 2 and the mounting shell 1.Disassemble the top protection bin 2, insert several fuses 32 between several sorting sheets 31, and slide the active block 13 vertically to the inside of the lowest sorting sheet 31. At this time, the replaced several fuses 32 are all located above the normally used fuses 32 inside the limiting ring 4 and the fitting ring 41. The replacement of several fuses 32 is completed. If a fuse is blown again, the staff can replace the used fuse 32 by sliding the active block 13 vertically again.

[0020] One of the sorting plates 31 has an alignment groove 34 inside, and the active block 13 slides inside the alignment groove 34; there are several sorting plates 31, and the sorting plate 31 located at the bottom has an alignment groove 34 inside, so that the active block 13 can be inserted into the bottom sorting plate 31, thereby completing the work of driving the sorting plate 31 and the fuse 32 to move, so that the staff can complete the replacement of the fuse 32 by vertically sliding the driven plate 3.
[0021] A fixing seat 42 is fixedly connected between the limiting ring 4 and the mounting shell 1, and an adjusting block 43 is fixedly connected to the inner wall of the mounting shell 1; the fixing seat 42 fixed between the limiting ring 4 and the mounting shell 1 is used to provide support for the limiting ring 4, so that the limiting ring 4 can be fixed in a suitable position, thereby providing auxiliary support for the connection between the fuse 32 and the connecting block 12, and when the staff slides the driven plate 3 horizontally, the fuse 32 in use located inside the limiting ring 4 and the fitting ring 41 can be fixed by the limiting position of the limiting ring 4, ensuring that the fuse 32 can be removed from between the sorting pieces 31 when the circuit is in normal use Disengagement allows the driven plate 3 to move vertically, thereby completing the reinstallation of several intact fuses 32 between the sorting plates 31 for easy use next time, and the adjustment block 43 fixed on the inner wall of the installation shell 1 is used to reset the fitting ring 41, and a spring is fixed between the adjustment block 43 and the fitting ring 41, so that when the fuse 32 applies a force to the fitting ring 41 to cause the fitting ring 41 to move, the spring between the adjustment block 43 and the fitting ring 41 will store energy until the fuse 32 slides between the limiting ring 4 and the fitting ring 41, at which time the fitting ring 41 will return to its original position, completing the limiting work of the fuse 32.
[0022] The top protection bin 2 and the bottom picking bin 21 are both slidably connected to the corresponding sides of the top protection bin 2 and the bottom picking bin 21, and a pushing block 51 is fixedly connected to one side of the connecting buckle 5; the sliding connecting buckle 5 on the corresponding sides of the top protection bin 2 and the bottom picking bin 21 is used to respectively engage the top protection bin 2 and the bottom picking bin 21 with the two ends of the installation shell 1, so that the top protection bin 2 and the bottom picking bin 21 can be fixed to the two ends of the installation shell 1 to complete the protection of the interior of the installation shell 1, and springs are installed between the connecting buckle 5 and the top protection bin 2 and the bottom picking bin 21.

When the fuse is blown, the staff can slide the active block 13 vertically again, so that the active block 13 drives the driven plate 3 and the sorting piece 31 and the fuse 32 to move, and the fuse 32 located above will replace the fuse 32 whose internal fuse has been blown and slide. When the last fuse 32 between the sorting pieces 31 is used, the staff can slide the driven plate 3 horizontally. The fuse 32 between the limiting ring 4 and the fitting ring 41 is limited by the limiting ring 4, so that the driven plate 3 will only drive the sorting piece 31 to move horizontally. Then the staff can slide the active block 13 out of the inside of the driven plate 3 so that the driven plate 3 can move vertically. Then the staff can slide the driven plate 3 vertically so that the sorting piece 31 is located at the fuse 32 being used. The top protective compartment 2 is disassembled by canceling the engagement between the top protective compartment 2 and the mounting shell 1, and then several fuses 32 are respectively inserted between several sorting plates 31, and the active block 13 is vertically slid to the inside of the lowest sorting plate 31. At this time, the several replaced fuses 32 are all located above the normally used fuses 32 inside the limiting ring 4 and the fitting ring 41. When a fuse blows again, the staff can replace the used fuse 32 by vertically sliding the active block 13 again.
