[0016] (III) Beneficial effects
[0017] The utility model provides a current limiting fuse fixture, which has the following beneficial effects:
[0018] The current limiting fuse clamp improves the existing elastic clamp and adds an anti-loosening hook on the outside of the elastic clamp. The anti-loosening hook and the elastic clamp are tightly matched. When the current limiting fuse is installed, the anti-loosening hook is stuck in the external clamping hole of the elastic clamp, thereby blocking the outlet of the elastic clamp. In this way, the current limiting fuse will be fixed by the anti-loosening hook and will not loosen or fall off. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] like Figure 1-5As shown, the utility model provides a technical solution: a current limiting fuse fixture, including a current limiting fuse 1, a first bolt 2, an elastic clamp 3, an anti-loosening hook 4, a conductor 5, an insulating support 6, a base 7 and a second bolt 8.
[0027] The elastic clamp 3 includes a fixing portion 31, a clamping portion 32 and an anti-slip flange 33. The current-limiting fuse 1 is clamped in the clamping portion 32. The anti-slip flange 33 extends outward. A clamping slot 330 is provided on the outer side of the anti-slip flange 33. The size of the anti-slip flange 33 is smaller than the outer diameter of the clamping portion 32.
[0028] The insulating support 6 is fixed to the base body 7 by means of second bolts 8 .
[0029] The anti-loosening hook 4 includes a rotating part 41 and a clamping part 42, wherein the inner diameter of the clamping part 42 is smaller than the inner diameter of the rotating part 41, and the clamping part 42 is clamped on the bayonet 330. When the anti-loosening hook 4 is fixed on the elastic clamping plate 3, the opening size of the anti-dropping flange 33 has been limited by the clamping part 42, and therefore the current-limiting fuse 1 will not fall off from the opening of the anti-dropping flange 33.
[0030] A conductor 5 is provided between the elastic clamping plate 3 and the insulating support 6 , and the elastic clamping plate 3 is fixed to the conductor 5 and the insulating support 6 in sequence by means of a first bolt 2 .
[0031] The current-limiting fuse 1 is clamped on the inner side of the elastic clamp 3 , and the anti-loosening hook 4 is rotatably installed on the outer side of the elastic clamp 3 .
[0032] The fixing portion 31 is respectively provided with a thread groove 310 and a clamping groove 311 . The first bolt 2 is threadedly connected to the thread groove 310 . The rotating portion 41 is movably installed in the clamping groove 311 .
[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.
[0034] When in use, firstly, the current-limiting fuse 1 is clamped into the clamping portion 32 of the elastic clamp 3, and then the anti-loosening hook 4 is rotated to clamp the clamping portion 42 on the anti-loosening hook 4 into the clamping portion 330 on the outer side of the anti-dropping flange 33, thereby closing the outlet of the elastic clamp 3 to prevent the current-limiting fuse 1 from loosening or falling off from the outlet.
[0035] To sum up, the current limiting fuse clamp improves the existing elastic clamp by adding an anti-loosening hook on the outside of the existing elastic clamp. The anti-loosening hook and the elastic clamp fit tightly together. When the current limiting fuse is installed, the anti-loosening hook is stuck in the external clamping mouth of the elastic clamp, thereby blocking the outlet of the elastic clamp. In this way, the current limiting fuse will be fixed by the anti-loosening hook and will not loosen or fall off.
