Since the transmission groove 14 and the surface of the rotating ring 3 are at a certain angle, the transmission rod 21 moves in the transmission groove 14 and drives the sliding block 4 to move on the surface of the fixed block 5. When the sliding block 4 moves, the semicircular groove 20 contacts the cable. Under the clamping of multiple groups of semicircular grooves 20, the cable is connected and fixed in the circuit breaker switch body 1.

[0033] The baffle plate 19 corresponds to the receiving groove 9, and the baffle plate 19 is clamped in the receiving groove 9. The size of the baffle plate 19 is the same as that of the receiving groove 9, and the size of the notch 11 is the same as that of the limit block 2.

[0037] Due to the elasticity of the spring 10, the spring 10 will push the baffle 19 to move, and the movement of the baffle 19 will drive the limit block 2 to move, so that the second tooth groove 18 is locked with the first tooth groove 17 to prevent the rotating ring 3 from rotating, thereby achieving the stability of the cable connection and fixation in the circuit breaker switch body 1.

[0038] In actual use, the circuit breaker switch body 1 is an electrical device that plays a protective role in the power system and is widely used in various types of electrical equipment. The cable is connected to the circuit breaker switch body 1.
