[0035] Example 2

[0036] Reference Figures 2 to 6, which is the second embodiment of the present invention, and is different from the first embodiment in that it also includes a rod body component 100. In the previous embodiment, the drop-out fuse maintenance and disassembly device includes a rod body component 100, including a fuse tube 101, a connecting component 102 arranged below the fuse tube 101, a pushing component 103 installed on the connecting component 102, and a rotating component 104 installed on the connecting component 102.

[0037] Furthermore, the connecting assembly 102 includes a bottom rod 102a arranged below the melting tube 101, a first slide groove 102b opened on the bottom rod 102a, a first connecting sleeve 102c fixedly connected to the bottom rod 102a, a middle rod 102d threadedly connected to the first connecting sleeve 102c, a second connecting sleeve 102e fixedly connected to the middle rod 102d, a top rod 102f threadedly connected to the second connecting sleeve 102e, a second slide groove 102g opened on the top rod 102f, a right-angle hook 102h fixedly connected to the top rod 102f, and a blocking frame 102i fixedly connected to the top rod 102f. The bottom rod 102a, the middle rod 102d and the top rod 102f are all insulating rods. When the overall length needs to be increased, the number of the middle rods 102d can be increased.

[0038] Furthermore, the pushing assembly 103 includes a guide ring 103a arranged on the top of the bottom rod 102a, the middle and both ends of the middle rod 102d, and the middle and bottom of the top rod 102f, grooves 103b arranged at the upper and lower ends of the guide ring 103a, a first sliding column 103c slidably connected to the bottom rod 102a, a first push rod 103d fixedly connected to the first sliding column 103c, a second push rod 103e slidably connected in the middle rod 102d, the second push rod 103e is slidably connected to the guide ring 103a, the groove 103b on the guide ring 103a can ensure that the first push rod 103d, the second push rod 103e and the third push rod 201a can pass through the guide ring 103a smoothly, an abutment ring 103f fixedly connected to the second push rod 103e, and a first elastic member 103g installed between the abutment ring 103f and the guide ring 103a, the first elastic member 103g maintains the thrust on the abutment ring 103f.

[0048] When in use, when it is necessary to disassemble the melting tube 101, the operator can assemble the bottom rod 102a, the middle rod 102d and the top rod 102f into a whole, and then operate the rod body to make the right-angle hook 102h hook the pull ring on the melting tube 101, and then pull the rod body downward to disconnect the melting tube 101 from the connecting buckle, so that the melting tube 101 is kept nearly parallel to the ground, and then the rotating ring 104c can be rotated to make the first push rod 103d push the second push rod 103e and the third push rod 201a to rise in turn, thereby driving the follower block 201d to rise, and the rising follower block 201d It will drive the clamping assembly 204 to rise. When the clamping assembly 204 rises to the point where the molten tube 101 is between the clamping jaws 204a, continue to operate the follower block 201d to rise. At this time, the abutment column 202c will abut against the blocking frame. At this time, the sliding support rod 202a and the clamping assembly 204 will not be able to move further upward. The follower block 201d that continues to rise will push the guide slide groove 203b to move upward. The upward guide slide groove 203b will conduct the two sets of clamping jaws 204a to approach each other, thereby clamping the molten tube 101. After clamping the molten tube 101, push the rod body upward to remove the molten tube 101.

[0049] In summary, through the coordinated use of the sliding component 201, the abutment component 202, the guide component 203 and the clamping component 204, the clamping and disassembly of the melt tube 101 can be achieved, which can effectively prevent the melt tube 101 from accidentally slipping during the operation and causing safety accidents. It is also convenient for the operator to use and can disassemble the melt tube 101 more quickly.
