[0023] like Figures 1 to 4As shown, the embodiment of the utility model described in the embodiment of the present invention is a live self-locking anti-electric shock device for wind power, comprising a first insulating rod 1; a round hook 12 is fixed to the top of the first insulating rod 1; the end of the round hook 12 away from the first insulating rod 1 is slidably connected to the connecting rod 13; the top of the first insulating rod 1 is fixed to a first fixing rod 14; the middle part of the end of the round hook 12 close to the connecting rod 13 is fixed to a first spring 15; the other end of the first spring 15 is fixed to the inside of the connecting rod 13; the inside of the connecting rod 13 is fixed to a first pull rope 16; the first pull rope 16 is arranged through the inside of the round hook 12 and the first insulating rod 1; a pair of limit plates 17 are symmetrically arranged and fixed to one end of the connecting rod 13 close to the first fixing rod 14; a slot 18 is provided at one end of the connecting rod 13 close to the first fixing rod 14; when working, Hold the first insulating rod 1 so that the round hook 12 is close to the wire, and then adjust the wire so that it is under the limit plate 17, and then pull the first insulating rod 1 downward, and the wire squeezes the limit plate 17 to drive the connecting rod 13 to slide along the round hook 12, and separate the connecting rod 13 from the first fixing rod 14, and then put the wire into the inside of the round hook 12. After the wire is separated from the limit plate 17, the connecting rod 13 will slide under the elastic force of the first spring 15, and make the first fixing rod 14 enter the inside of the slot 18, thereby locking the wire inside the round hook 12, the connecting rod 13, and the first fixing rod 14 so that it will not easily fall off. Through the above structure, when the wind power circuit is inspected and grounded, the device can be kept more stably connected to the line, reducing the occurrence of circuit grounding disconnection caused by the separation of the wire and the device, thereby improving the safety of use.

[0024] like Figures 1 to 3As shown, a card slot 2 is provided in the middle of the side wall of the slot 18; a fixing plate 21 is fixedly connected to the inside of the first fixing rod 14; a second spring 22 is fixedly connected to the side wall of the fixing plate 21; a card block 23 is fixedly connected to the other end of the second spring 22; the card block 23 is slidably connected to the middle of the first fixing rod 14; a second pull rope 24 is fixedly connected to the end of the card block 23 facing the fixing plate 21; the other end of the second pull rope 24 is sleeved on the middle of the first pull rope 16; during operation, after the wire enters the inside of the round hook 12, the connecting rod 13 will slide to insert the first fixing rod 14 into the inside of the slot 18. In this process, the card block 23 will be squeezed by the end of the slot 18 and slide toward the inside of the first fixing rod 14. After the slot 18 moves to the specified position, the block 23 will be inserted into the inside of the slot 2 under the elastic force of the second spring 22, thereby limiting the movement of the connecting rod 13 and further reducing the occurrence of separation of the wires from the device. When it needs to be opened, the first pull rope 16 is pulled. Since the connecting rod 13 is restricted from moving, the first pull rope 16 will first pull the second pull rope 24, and then pull the block 23 to slide out of the inside of the slot 2, releasing the restriction on the movement of the connecting rod 13. Then the connecting rod 13 will slide under the pull of the first pull rope 16, allowing the wires to be detached. Through the above structure, the occurrence of wire separation can be further reduced when using the device to connect the line, and the connection with the wires can be conveniently released after use.

Through the above structure, the connection between the device and the circuit cable can be conveniently released, thereby improving the convenience of use of the device.

[0027] like Figures 1 to 2As shown, a dust-proof film 5 is fixed to the middle of the outer wall of the circular hook 12; the other end of the dust-proof film 5 is fixed to the end of the connecting rod 13; when working, when in use, external impurities will be blocked by the dust-proof film 5 and will not easily enter between the circular hook 12 and the connecting rod 13, thereby reducing the occurrence of sliding jams of the connecting rod 13 and improving the stability of the device.

[0028] like Figures 1 to 2 As shown, a buffer block 6 is fixed to the inside of the slot 18; the buffer block 6 is arranged on the side of the slot 18 away from the first fixing rod 14; when working, the connecting rod 13 will slide due to the elastic force of the first spring 15, and will collide with the buffer block 6 after the first fixing rod 14 enters the slot 18.

[0030] During operation, the first insulating rod 1 is held in the hand so that the round hook 12 is close to the wire, and then the wire is placed under the limit plate 17 by adjusting the first insulating rod 1, and then the first insulating rod 1 is pulled downward, and the limit plate 17 is squeezed by the wire to drive the connecting rod 13 to slide along the round hook 12, and the connecting rod 13 is separated from the first fixing rod 14, and then the wire is put into the inside of the round hook 12. After the wire is separated from the limit plate 17, the connecting rod 13 will slide under the elastic force of the first spring 15, and the first fixing rod 14 will enter the inside of the slot 18, thereby locking the wire in the inside of the round hook 12, the connecting rod 13, and the first fixing rod 14 so that it will not be easily detached. After the wire enters the inside of the round hook 12, the connecting rod 13 will cause the first fixing rod 14 to be inserted into the inside of the slot 18 when sliding. In this process, the card block 23 will be squeezed by the end of the slot 18 and slide toward the inside of the first fixing rod 14. After the slot 18 moves to the specified position, the card block 23 will be inserted into the card slot 2 under the elastic force of the second spring 22. 3, and then the through hole 32 is pulled downward to pull the second insulating rod 3 to pull the first pull rope 16 downward, so that the second insulating rod 3 drives the first pull rope 16 to pull down, so that the cable can be separated with one hand.

After the first fixing rod 14 enters the slot 18, it will collide with the buffer block 6, and the buffer block 6 will reduce the impact force during the collision.
