[0015] Beneficial effects of the present invention:

[0016] 1. The present invention pushes the vertical rod through the first connecting rod and the second connecting rod, and the vertical rod slides downward along the limit frame, so that the lower clamping plate moves downward and separates from the upper clamping plate, exposing the movable groove, which is convenient for the movement of the longitudinal rod.

When the position of the connecting plate needs to be switched, the pressure plate is moved upward before opening the sealing cover and separated from the surface of the box body. After the extrusion contact is released, the connecting plate can be driven to slide and adjust through the vertical plate. In the process of the movement of the stud rod, the two fixed blocks cooperate with the push rod to move the connecting column in the vertical direction through the movement of the transmission belt. When the pressure plate moves upward, the connecting column moves the moving block downward along the vertical groove, and the connecting plate moves downward at the same time, and vice versa.

[0019] 4. The present invention releases the squeeze limit effect of the pressure plate and the squeeze contact between the connecting piece and the terminal, thereby facilitating the sliding of the connecting piece. Similarly, when the pressure plate is in squeeze contact with the surface of the current wiring unit, the terminal piece will also be in squeeze contact with the terminal, thereby ensuring the passage state. If only a simple inspection is performed on the inside of the box body and there is no need to adjust the position of the connecting piece, there is no need to unlock the position of the vertical plate by the screw at the beginning, and the vertical plate and the connecting piece maintain the position of the passage.

[0020] 5. Compared with the prior art, the present invention adjusts the current flow direction of the current wiring unit through the action of the connecting component and the adjusting component to form a secondary circuit and avoid the current transformer from generating an open circuit. The adjustment of the connecting piece has a certain guiding and indicating effect. After the adjustment is completed, the stability of the connection between the connecting piece and the terminal can be maintained. When threading, the wires can be threaded according to the prompt position, thereby avoiding misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

By rotating the knob 312, the screw 313 can rotate the two groups of studs 38 at the same time under the effect of the transmission of the transmission belt 35, driving the pressure plate 39 to rise or fall. When the position of the connecting piece 17 needs to be switched, the pressure plate 39 is moved upward before opening the sealing cover to separate it from the surface of the box body 1. After the extrusion contact is released, the connecting piece 17 can be driven to slide and adjust through the vertical plate 32. In the process of moving the stud rod 38, the two fixing blocks 36 and the push rod 316 are matched through the movement of the transmission belt 35.

The upper clamping plate 26 is fixed to the box body 1. A lower clamping plate 25 is slidably installed at the bottom of the movable groove 210, and the upper clamping plate 26 and the lower clamping plate 25 are clamped on the upper and lower sides of the longitudinal rod 212. A vertical rod 21 is fixed to one end of the lower clamping plate 25, and the top of the vertical rod 21 is rotatably connected to the first connecting rod 23 through a bearing, and the other end of the first connecting rod 23 is rotatably connected to the second connecting rod 24 through a rotating shaft, and the other end of the second connecting rod 24 is rotatably connected to the outer surface of the first sealing cover 13 through a rotating shaft. The box body 1 is fixed with a limited position frame 22 on both sides corresponding to the vertical rod 21, and the vertical rod 21 is rotated along the limit position. The frame 22 slides, and when the first sealing cover 13 is flipped open, the first connecting rod 23 and the second connecting rod 24 push the vertical rod 21, and the vertical rod 21 slides downward along the limit frame 22, and the lower clamping plate 25 moves downward to separate from the upper clamping plate 26, exposing the movable groove 210, which is convenient for the movement of the longitudinal rod 212. In this structure, the upper clamping plate 26 and the lower clamping plate 25 can be connected by Velcro or elastic rubber strips. When the box body 1 needs to be sealed, the movable groove 210 is blocked, and the position of the longitudinal rod 212 is also limited, preventing the longitudinal rod 21 from being moved. 2 moves and needs to adjust the position of the connecting piece 17, the adjustment component 3 and the connecting piece 17 can be driven to slide by moving the cross bar 29 and the longitudinal bar 212 along the moving groove 210 to switch the position in contact with the terminal 18.

[0035] When the device is used, the tops of the current wiring unit 15 and the voltage wiring unit 16 are protected separately by the first sealing cover 13 and the second sealing cover. When the meter needs to be changed, the two sets of studs 38 can be rotated at the same time by rotating the knob 312 under the effect of the transmission belt 35, driving the pressure plate 39 to rise or fall. When the position of the connecting piece 17 needs to be switched, the pressure plate 39 is moved upward before opening the sealing cover to separate it from the surface of the box body 1. After the extrusion contact is released, the connecting piece 17 can be driven to slide and adjust through the vertical plate 32.

The technical effect of this part is that when the extrusion limiting effect of the pressure plate 39 is released, the extrusion contact between the connecting piece 17 and the terminal 18 is released, thereby facilitating the sliding of the connecting piece 17. Similarly, when the pressure plate 39 is in extrusion contact with the surface of the current wiring unit 15, the terminal piece will also be in extrusion contact with the terminal 18, thereby ensuring the passage state. If only a simple inspection is performed on the inside of the box body 1, and the position of the connecting piece 17 does not need to be adjusted, it is not necessary at the beginning. The position of the vertical plate 32 is unlocked by the screw 313, and the vertical plate 32 and the connecting piece 17 keep the position of the passage unchanged. When the first sealing cover 13 is flipped open, the vertical rod 21 is pushed by the first connecting rod 23 and the second connecting rod 24, and the vertical rod 21 slides downward along the limit frame 22, and the lower clamping plate 25 is moved downward to separate from the upper clamping plate 26, so that the movable groove 210 is exposed to facilitate the movement of the longitudinal rod 212. In this structure, the upper clamping plate 26 and the lower clamping plate 25 can be bonded by Velcro. When the box body 1 needs to be sealed, the movable groove 210 is blocked, and the position of the longitudinal rod 212 is also limited to prevent the longitudinal rod 212 from moving. When adjusting the position of the connecting piece 17, the adjustment component 3 and the connecting piece 17 can be driven to slide by moving the cross bar 29 and the longitudinal bar 212 along the moving groove 210 to switch the position in contact with the terminal 18. The cross bar 29 slides along the connecting plate 27, and the switching and movement of the connecting piece 17 can be completed on the outside of the box body 1. All objects in direct contact with the connecting piece 17 in this device are made of insulating materials. The plug ring 28 at the bottom of the connecting plate 27 can guide the insertion of the access end connecting wire 12 to avoid the wrong insertion of the connecting wire 12.
