[0036] In order to make the purpose, advantages and features of the present invention more clear, the following is a further detailed description of a spring fastening hook proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following specific embodiments, the advantages and features of the present invention will be more clear.

[0037] See also Figures 1 to 3 The present embodiment provides a spring fastening hook, which mainly includes a hook body, a connecting rod 1 and a double torsion spring 2. The hook body is suspended on an external cable 01, and an external working device 02 is installed. The double torsion spring 2 is then installed on the hook body through the connecting rod 1. The hook body and the external cable 01 are fastened by the double torsion spring 2 to prevent the hook body from sliding along the external cable 01, thereby achieving the purpose of reliably hanging the external working device 02 on the external cable 01.

[0038] The external working device 02 can be a charge indicator, which can be securely and reliably fastened to the cable 01 via the hook, indicating that the cable 01 is charged and preventing accidents. Alternatively, it can be a wireless communication device, which transmits data in real time and monitors data related to the cable 01. Of course, other working devices 02 with different functions can be designed based on actual needs, and these are not listed in this embodiment.

[0039] Among them, the hook body mainly includes a connecting plate 3, two mounting plates 4 and two baffles 5; the upper end of the connecting plate 3 is provided with a hanging part 6, which is mainly used to hang the external cable 01, and the lower end is provided with a mounting part 7, which is mainly used to install the external working device 02, and the hanging part 6 and the mounting part 7 are located on the same side of the connecting plate 3.

[0040] Specifically, the aforementioned hanging portion 6 is an arc-shaped plate; the inner concave surface of the arc-shaped plate is disposed toward one side of the mounting portion 7. A top plate 8 is disposed on each of the two opposing side walls of the hanging portion 6. The length of the top plate 8 is disposed in the vertical direction, and the top plate 8 is located at the highest point of the arc-shaped plate. The top plate 8 prevents the external cable 01 from sliding to the side of the mounting plate 7 when located on the upper side of the hanging portion 6, thereby blocking the external cable 01 and facilitating the insertion of the external cable 01 into the inner concave surface of the arc-shaped plate. Furthermore, grooves are disposed on the two axially opposing side walls of the arc-shaped plate, with one end of each of the two top plates 8 disposed within the grooves. The grooves are configured to adjust the height of the top plate 8 and the bending angle of the top plate.

[0041] The mounting portion 7 is a mounting horizontal plate, and the angle between it and the connecting plate 3 is a right angle; a first mounting hole 9 is provided on the mounting horizontal plate, and the mounting horizontal plate is connected to the external working device 02 through the first mounting hole 9 via an external mounting part, thereby facilitating fixing the external working device 02 on the mounting horizontal plate.

[0042] One end of the two mounting plates 4 is connected to the side walls of the connecting plate 3 near the ends of the suspension portion 6, and is located on the same side of the connecting plate 3 and extends outward from the suspension portion 6. One end of the two baffles 5 is connected to the two opposite side walls of the suspension portion 6, and the length of the baffles 5 is arranged along the length of the external cable 01. The connecting rod 1 is rotatably mounted on the two mounting plates 4, with its two ends located on the side away from each other of the two mounting plates 4. The two spiral segments of the double torsion spring 2 are respectively fitted onto the two ends of the connecting rod 1, and the two ends are respectively fixed to the two mounting plates 4; in the initial state, the retaining ring portion of the double torsion spring 2 abuts the bottom of the two baffles 5, and abuts the external cable 01 when the suspension portion 6 is suspended on the external cable 01.

[0043] For details, see Figure 6 , connecting screw holes are provided at both ends of the connecting rod 1 along its axial direction; the two mounting plates 4 are respectively provided with second mounting holes 10 adapted to the connecting rod 1, and the connecting rod 1 passes through the two second mounting holes 10 and is rotatably matched with the two mounting plates 4; see Figure 1 、 Figure 4 and Figure 5The two spiral sections of the double torsion spring 2 are respectively mounted on the two ends of the connecting rod 1. The two ends of the connecting rod 1 are connected with connecting bolts 12 through connecting screw holes. The inner side of the nut at the end of the connecting bolt 12 abuts against the spiral section of the double torsion spring 2 to limit its axial movement; the two mounting plates 4 are respectively provided with clamping holes 11 that are compatible with the ends of the double torsion spring 2, and the two ends of the double torsion spring 2 are respectively clamped in the two clamping holes 11.

[0044] In addition, the hook of the utility model can be used in conjunction with a wireless communication device capable of transmitting data to perform real-time data transmission and monitor cable-related data in real time. The hook can also be made of other materials to expand its application in other fields.
