[0021] Technical effects and advantages of the present invention:

[0022] 1. The present invention connects the mounting block and the fixing bolt by setting a rotating fixing bolt, and the side of the second rubber sealing pad is meshed with the groove and the serrated groove of the first rubber sealing pad to seal the middle of the cable connection. At the same time, the sleeve hole inside the protective sleeve is sleeved on the outer surface of the buffer head and fits on the sides of the first protective shell and the second protective shell. The protective sleeve is shrunk by heating to fit the surfaces of the first protective shell and the buffer head, and the second protective shell and the buffer head, thereby completing the sealing of the two ends, thereby achieving a waterproof and moisture-proof effect. Through the protection of the first protective shell and the second protective shell, the insulation layer of the cable connection is ensured to be intact, and the cable is prevented from short circuiting or leaking due to damage to the insulation layer.

[0023] 2. The present invention arranges a second clamping plate inside the second shell and a first clamping plate inside the first shell, and the movable plate descends inside the second movable groove and the first movable groove respectively, and the two ends of the cable are clamped on the top of the second clamping plate and the first clamping plate, so that they are respectively clamped on the two ends of the cable with the upper clamping plate at the bottom of the movable plate, thereby fixing the cable to avoid pulling of the cable during laying, which may cause the connection to loosen or fall off, thereby improving the firmness of the cable connection.

[0024] 3. The present invention sets the diameter of the conical groove away from the rotating knob to be larger than the diameter of the end close to the rotating knob. Since one end of the conical groove is smaller than the other end, by rotating the rotating tube, the rotating tube is inside the first shell or the second shell, so that the conical groove is respectively clamped at the two ends of the cable connection. Not only can the cable be clamped to prevent the cable connection from falling off due to pulling, but also the cable connection is tightened by pulling the cable, thereby further maintaining the stability of the cable.

[0025] 4. The present invention uses a connecting strip and a clamping block, which are clamped inside the connecting frame and the clamping rod, so that the positions of the second rubber sealing pad and the first rubber sealing pad correspond to each other, thereby engaging with each other to produce a seal. At the same time, the fixing block and the mounting block are quickly positioned, which makes it easy to install them through fixing bolts, making the installation of the device more convenient and avoiding the influence of the gravity of the cable on the installation and fixation of the device.

[0026] The present invention provides a flexible rod and a return spring on the surface. When the cable is bent, the return spring and the flexible rod are used to buffer it, thereby preventing the cable from being excessively bent or the connection between the first protective shell and the second protective shell and the cable from being hit, so that the frames of the first protective shell and the second protective shell press on the cable, thereby causing damage to the surface of the cable, thereby reducing the impact of the protective installation component itself on the cable, and at the same time, by resetting the flexible rod and the return spring, the gap in the protective sleeve caused by excessive bending of the cable and the impact on the sealing of the two ends of the cable connection is reduced.
