The concave ring is connected to the threaded convex ring and the threaded concave ring. The left fixing ring 3 and the right fixing ring 6 are provided with a tightening device, which is composed of a protective shell 7, a tightening piece 8 and a fixing rod 10. One end of the protective shell 7 is fixedly connected with a tightening piece 8, and a clamping groove 9 is provided on the tightening piece 8. The tightening piece 8 penetrates the protective shell 7 and extends out. A fixing rod 10 is rotatably provided in the middle of the protective shell 7. A first fixing block 11 and a second fixing block 12 are inserted into the left and right sheaths;

[0026] Left sheath: including left sheath 1, left connecting ring 2 and left fixing ring 3:

[0027] Left sleeve 1: Features include elasticity and silicone material; its function is to adapt to different terminal sizes through expansion and contraction, and the silicone material achieves good insulation.

[0028] Left connecting ring 2: It is characterized by a threaded connection convex ring. Its function is to cooperate with the threaded concave ring of the right connecting ring 5 to achieve a tight connection between the left and right sheaths;

[0029] Left fixing ring 3: It is characterized by a special flat section and a large end diameter. Its function is to increase the contact area and stability with the connecting parts and improve the overall fixing effect.

[0030] Right sheath: including right sheath 4, right connecting ring 5 and right fixing ring 6:

[0031] Right sleeve 4: Same as left sleeve 1, elastic and silicone material, to achieve insulation and size adaptation.

[0032] Right connecting ring 5: It is characterized by a threaded connecting concave ring, which cooperates with the convex ring of the left connecting ring 2 to complete the assembly.

[0033] Right fixing ring 6: Same as left fixing ring 3, enhancing the connection stability of the right sheath.

[0034] Tightening device: protective shell 7, tightening sheet 8, fixing rod 10:

[0035] Protective shell 7: It is characterized by protection and support. It is used to accommodate and fix other components.

[0036] The tightening piece 8 is characterized by a slot 9. The function is to achieve a tightening action by cooperating with a fixing rod 10.

[0037] The fixing rod 10 is characterized by having a rotating blade and can rotate. The function is to achieve a tightening effect by engaging with the card slot 9 through rotation.

[0038] The first fixing block 11 and the second fixing block 12 are characterized by being composed of different numbers of semicircular blocks, and their function is to provide a more accurate and diversified fixing support method for the battery terminal to meet different needs.

[0039] like Figure 1 As shown, in some embodiments, the left cover 1 and the right cover 4 are both telescopic covers, and the left cover 1 and the right cover 4 are both silicone insulating covers; the characteristics of the telescopic covers enable them to adapt to a variety of battery terminals of different sizes and shapes, improving the versatility and adaptability of the protective cover, and the silicone has good insulation properties, which can effectively prevent the battery terminals from leaking or short-circuiting with the outside world, thereby ensuring safety during use. At the same time, the silicone material also has a certain degree of elasticity and softness, and is not easy to cause damage to the battery terminals during installation and use.

[0040] like Figure 2 As shown, in some embodiments, the left fixing ring 3 and the right fixing ring 6 both have a flat section, and the end diameters of the left fixing ring 3 and the right fixing ring 6 are larger than the inner diameter; the design of the flat section increases the contact area with the surface of the connected object, which can make the fixation more stable and not easy to shake or shift. The design that the end diameter is larger than the inner diameter can play a certain guiding role during installation, which is convenient for fast and accurate installation positioning, and can also enhance the tightness and firmness of the connection to prevent the protective cover from falling off easily.

[0041] like Figure 3As shown, in some embodiments, the fixing rod 10 has a rotating blade, and the rotating blade engages with the card slot 9; by rotating the fixing rod 10, the rotating blade engages with the card slot 9, and the tightening operation of the clamping sheet 8 can be achieved, thereby enhancing the fixing effect of the entire sheath, ensuring that the protective sheath will not loosen or shift during use, and ensuring its effective protection and stable connection to the battery terminal.

[0043] The two semicircular block designs of the first fixing block 11 can provide a relatively simple fixing method to adapt to some specific situations and requirements.

[0044] The three semicircular blocks of the second fixing block 12 provide more contact points and support points, making the fixation more firm and stable, adapting to different installation conditions and requirements, increasing the diversity and flexibility of the entire device in terms of fixation, and being able to better meet the needs of battery terminal fixation in different scenarios. For example, when a stronger fixing force or a more complex installation environment is required, the second fixing block 12 can be used; while in some simpler occasions, the first fixing block 11 may be more suitable.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
