A plurality of second clamping rods 207 are installed on the side close to each other of the two mounting plates 206, and the second clamping rods 207 are respectively inserted into the second clamping grooves 104 on the copper bus 102. A connecting rod 205 is installed on the side away from each other of the two mounting plates 206. The ends of the connecting rod 205 are inserted into the interior of the end box 202. The two connecting rods 205 are respectively fixedly connected to the two movable plates 203. A side groove 208 is opened on the front of the end box 202. A side plate 209 is installed on the front of the movable plate 203. Two racks 210 are symmetrically arranged on the front of the connection box 201. The two racks 210 are respectively fixedly connected to the two side plates 209. A gear 211 is meshed and connected between the two racks 210. The gear 211 Rotate, the two movable plates 203 approach each other, so that the first clamping rod 204 on the movable plate 203 enters the connection box 201 and is clamped into the first clamping groove 103 on the slot body 101, and the two bus duct modules 1 are clamped, and at the same time the second clamping rod 207 is clamped into the second clamping groove 104, and the slot body 101 is further clamped and fixed, and the contact stability of the two copper bars 102 is ensured at the same time.
