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 belongs to the technical field of aviation, and particularly relates to an aviation wire bunching pipe joint dismounting device with high operation performance, which comprises a handle, a telescopic rod is inserted into one end of the handle in a penetrating manner, one end of the telescopic rod is connected with a fixing ring, and two ends of the fixing ring are respectively connected with a fixing sleeve. According to the device, the pull rod is pulled to enable the connecting block to drive the clamping pin to be separated from the clamping groove, then the telescopic rod is stretched out and drawn back according to the requirements of workers, and then the pull rod is loosened; at the moment, the clamping pins can reset under the action of the connecting blocks and the springs and are inserted into the corresponding clamping grooves to achieve fixation after the telescopic rods stretch out and draw back, so that the length of the tool handle can be conveniently adjusted, a user can apply force more easily, and the operability of workers is improved.

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.

The utility model discloses a toothbrush capable of cleaning four sides, and relates to the technical field of toothbrushes. The toothbrush capable of cleaning the four sides comprises a brush handle, a brush neck and a brush rod are integrally formed on the brush handle, and two first brush faces are integrally formed on the brush rod; a second brush surface is integrally formed on the brush rod; a third brush surface is integrally formed on the second brush surface; bristles are planted on the first brush faces, the second brush faces and the third brush faces, and the second brush faces are located between the two first brush faces. According to the toothbrush capable of cleaning the four sides, the two first brush surfaces can effectively clean the two sides of teeth and gingiva, so that the phenomenon that brushing is not in place is avoided, the second brush surface can clean the plane position of the teeth, and the third brush surface can play an effective removing effect along with movement of the toothbrush, so that impurity residues are avoided; meanwhile, due to the arrangement of the third brush surface, the toothbrush can go deep into the deepest part of the oral cavity to thoroughly clean the teeth in the innermost part of the cavity in multiple directions without dead corners.
