The utility model provides a kind of installation device for wall pre-buried repeated grounding, and the grounding busbar and connecting body are connected in accommodating cavity by setting installation frame, installation frame is composed of two side plates and transverse plate and open-close mechanism that can be opened and closed, open-close mechanism opens, grounding busbar and connecting body are placed in installation frame, then open-close mechanism is closed, grounding busbar and connecting body are sleeved, open-close mechanism is in the back inner wall side of accommodating cavity;Using tool abutting clamping mechanism's resistance rod, so that grounding busbar and connecting body are tightly connected.The above technical scheme is adopted, the setting of open-close mechanism, when using, open-close mechanism can be directly entered from the opening side of accommodating cavity, and grounding busbar and connecting body are placed in installation frame, reduce the space occupation area when sleeving grounding busbar and connecting body;Resistance rod is provided with insertion hole, can be connected with the tool of screwing, compared with fixed rotating screw rod, it can extend outside accommodating cavity when screwing, and it is easier to exert force.

The utility model discloses a copper joint relates to joint technical field, including central pipe body, the intermediate position department outside central pipe body is fixedly connected with central fixed nut, the both sides of central pipe body outside respectively have the connecting nut of sleeve joint, the inside surface welding of connecting nut has internal thread ring, the outside of central pipe body is provided with the rotating assembly of facilitating rotating nut. This copper joint is through setting limit ring, hexagonal groove, round groove and ear piece, when using, central pipe body is used as medium delivery channel, and the connecting nut of both ends is used for and pipeline butt joint, when rotating connecting nut, can push limit ring to connecting nut, and connecting nut is clamped into hexagonal groove, and the thumb and forefinger of installation personnel buckle ear piece and rotate respectively, can complete the screwing locking of nut under the condition of no spanner etc. installation tool, and it is easier to force, has realized the function that hand twists and reinforces conveniently, and the problem that device does not have the function that hand twists and reinforces conveniently is solved.

The utility model belongs to the field of harness stripping device, concretely speaking is a kind of harness stripping device for harness processing, including base plate, the left side fixed connection of base plate has support frame no.
