At present, the ends of the external red and black wires of general power charger products on the market are equipped with alligator clips, which are used to fix the electrode ends of other electrical appliances to charge them. However, since only one end of the alligator clip is connected to the wire and there is no continuous wire at the other end, if the wire breaks or the contact is poor, the charging will be terminated or abnormal heat will be generated, which poses a great risk. In addition, another defect of the existing alligator clips is that the metal clip body is wrapped with a heat shrink tube, and the tip of the metal clip body is exposed to the outside, which puts the operator at risk of electric shock.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1

[0026] like Figure 1-3A power alligator clip shown includes: a main clip 1, a secondary clip 2, a first insulating shell 3 and a second insulating shell 4; the main clip 1 and the secondary clip 2 are rotatably connected; the first insulating shell 3 is fixedly connected to the main clip 1; the length of the first insulating shell 3 is greater than the length of the main clip 1; the second insulating shell 4 is fixedly connected to the secondary clip 2; the length of the second insulating shell 4 is greater than the length of the secondary clip 2.

[0027] In the present application, the main clamp 1 and the auxiliary clamp 2 are both made of metal materials, wherein the main clamp 1 and the auxiliary clamp 2 are both used to clamp wires or other terminals to achieve contact conduction. In order to avoid the risk of electric shock due to exposed metal at the front end of the crocodile clip, the present application respectively arranges a first insulating shell 3 and a second insulating shell 4 on the outside of the main clamp 1 and the auxiliary clamp 2, and the length of the two insulating shells is longer than the length of the internal metal material, so that the main clamp 1 and the auxiliary clamp 2 inside can be completely covered to avoid the risk of electric shock due to exposed metal.

[0028] In one embodiment, the first insulating shell 3 is fixedly connected to the outer surface of the main clip 1; the second insulating shell 4 is fixedly connected to the outer surface of the auxiliary clip 2. The insulating shells are fixedly connected to the outer surfaces of the main clip 1 and the auxiliary clip 2, so that the user can pinch the main clip 1 and the auxiliary clip 2 to open the alligator clip.

[0029] In one embodiment, the first insulating shell 3 extends to both sides and is fixedly connected to both sides of the main clamp 1 ; the second insulating shell 4 extends to both sides and is fixedly connected to both sides of the auxiliary clamp 2 .

[0030] In order to further improve the safety of the crocodile clip and prevent the user from contacting the metal clip part, at the control end of the crocodile clip, that is, the position where the crocodile clip is pinched, the insulating shell extends to both sides to wrap the sides of the main clip 1 and the auxiliary clip 2 to improve safety.

[0031] In one embodiment, it also includes: a connecting wire 5 for connecting to a power charger; the connecting wire 5 is fixedly connected to the main clip 1 and the auxiliary clip 2 respectively; the connecting wire 5 is also electrically connected to the main clip 1 and the auxiliary clip 2 respectively. In actual use, if the connecting wire 5 is loose between the alligator clip, the resistance and heat of the loose part will increase, and there is a risk of fire. In this application, the alligator clip uses a wire to connect the main clip 1 and the auxiliary clip 2 respectively. Even if one side has poor contact, the current can pass through the position with lower resistance on the other side, and will not generate large heat, which effectively reduces the risk of fire. In this application, the connecting wire 5 is connected to the auxiliary clip 2 at one end, and is connected to the main clip 1 at a middle part. It is connected to the main clip 1 and the auxiliary clip 2 through a connecting wire 5 instead of using two wires to connect, which can effectively reduce the production cost of the product.

[0032] In one embodiment, the middle of the main clip 1 is rotatably connected to the middle of the auxiliary clip 2. The main clip 1 and the auxiliary clip 2 are rotatably connected in the middle, which can balance the rotation distance of the crocodile clip and the opening force of the crocodile clip. If the rotating shaft 6 of the crocodile clip is too close to the clamping area, the opening distance of the clamping area will be too small. If the rotating shaft 6 is too close to the pinching position of the crocodile clip, it will be too strenuous for the user to pinch the crocodile clip to open.

[0033] In one embodiment, it further comprises: a rotating shaft 6, a first shaft hole 7 is opened in the middle of the main clamp 1; a second shaft hole 8 is opened in the middle of the auxiliary clamp 2; the rotating shaft 6 passes through the first shaft hole 7 and the second shaft hole 8 in sequence.

[0034] In this application, the rotating shaft 6 provides a fixing means for the main clamp 1 and the auxiliary clamp 2.

[0035] In one embodiment, the alligator clip further comprises: a torsion spring 9; one end of the torsion spring 9 abuts against the main clamp 1, and the other end of the torsion spring 9 abuts against the auxiliary clamp 2; the torsion spring 9 is also sleeved on the rotating shaft 6. The torsion spring 9 can keep the alligator clip elastic and can clamp the target wire or target terminal.

[0036] In one embodiment, a first fixing tooth 10 is disposed at one end of the main clamp 1 ; and a second fixing tooth 11 which can mesh with the first fixing tooth 10 is disposed at one end of the auxiliary clamp 2 .

[0037] The first fixed teeth 10 and the second fixed teeth 11 mesh with each other, which can increase the force on the clamped object and prevent the alligator clip from falling off the connection position.

[0038] In one embodiment, the first insulating housing 3 and the second insulating housing 4 are both provided with anti-slip grooves 12. The anti-slip grooves 12 can facilitate the user to pinch the alligator clip.

[0039] In one embodiment, the first insulating housing 3 and the second insulating housing 4 are both provided with polarity markings 13. The polarity markings can facilitate the user to identify the polarity of the wire connected to the alligator clip, thereby avoiding the danger of incorrect wiring.

[0040] In one embodiment, the main clamp and the auxiliary clamp are both provided with snap-fit ​​holes; the first insulating shell and the second insulating shell are both provided with snap buckles; during the assembly process, the two side walls of the first insulating shell form a limiting groove for accommodating the main clamp, the main clamp is placed inside the limiting groove of the first insulating shell, and then the snap buckle is snapped into the snap-fit ​​hole at the other end, so that the insulating shell and the metal clip can be easily and quickly assembled with each other, and the insulating shell and the metal clip can also be separated from each other again, so as to facilitate the maintenance of the crocodile clip.

[0041] In one embodiment, the ends of the main clamp 1 and the auxiliary clamp 2 are both provided with fixing portions for fixing the connecting line 5 .

[0042] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
