[0012] Beneficial effects of the present invention:

[0013] 1. The bus trough body is formed by connecting a plurality of expansion slots, through-wall slots and end slots to realize the modular design of the bus trough body, which is convenient for the transportation, storage and assembly of the bus trough body. At the same time, the first rib plate, the second rib plate and the third rib plate are installed in the bus trough body to improve the stability of the bus trough body structure. The second connection frame on one expansion slot and the second connection frame on another expansion slot are connected by bolts to realize the assembly of two adjacent expansion slots. By increasing or decreasing the number of expansion slots, the length of the bus trough body can be adjusted as needed.

[0014] 2. According to the length of the bus trough, select a suitable number of support bars, install one of the support bars at the bottom of the inner frame, and then use the clamping screws to install the plug connector on one support bar into the plug slot on another support bar, and so on, complete the assembly of multiple support bars, so that the structure formed by multiple support bars can support the bus trough. On the one hand, the bus trough is supported to improve the stability of the bus trough structure. On the other hand, a certain distance is created between the bus trough and the bottom of the inner frame to improve the safety of electricity use.

[0015] 3. Use the knob head to turn the support screw to increase the length of the support screw on the upper side of the support bar, thereby increasing the height of the structure formed by the support screw and the support bar, making it easier to adjust the distance between the bus trough and the bottom of the inner frame as needed.

[0017] 5. After the relative position of the locating rod and the bus trough is adjusted, connect one end of the valve to the air outlet of the inflation device, and then open the valve, use the inflation device to inject air into the elbow, and then the air flows into the vertical cylinders at both ends of the elbow. At this time, the air entering the vertical cylinder forces the piston to move downward in the vertical cylinder, so that the piston drives the pressure rod to move downward along the vertical hole and squeeze the locating rod, so as to achieve synchronous limiting of the locating rods on both sides of the reserved hole, without the need for staff to go back and forth between the two sides of the wall and floor to limit the relative position of the locating rod and the pipe sleeve. After opening the valve, the piston moves upward under the action of the spring rebound force, so that the pressure rod no longer squeezes the locating rod, which is convenient for limiting the relative position of the locating rod and the bus trough.
