In the figure: 1-outer joint A; 2-linker A; 3-a first fixing piece; 4-a connector; 401-connector a; 402-connector B; 5-linker B; 6-outer joint B; 7-second fixing piece.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown, the tool knuckle includes joint a2, link 4, and joint B5, where joint a2 is rotationally coupled to link 4, joint B5 is rotationally coupled to link 4, and the directions in which joint a2 and joint B5 rotate relative to link 4 may be the same or perpendicular. The end of the connector A2 remote from the connector 4 is connected to an extension A1 and the end of the connector B5 remote from the connector 4 is connected to an extension B6. The extension a1 and the extension B6 may be used to connect other parts of the tool, and when the tool is a pick-up, the extension a1 and the extension B6 may be used to connect pick-up, handle, quick-connect, etc. The joints A1 and B5 can be the same type or different types, as the external case requires.

Joint A2 and joint B5 are the U-shaped structure, and it specifically includes two vertical limits and a horizontal limit, and the structure is comparatively simple. The upper end and the lower end of the connecting piece 4 are both provided with connecting pieces. The connecting piece 4 can be an integrated piece or a split connecting piece. When the connecting piece 4 is a split connecting piece, the connecting piece is composed of a connecting piece A401 and a connecting piece B402 which are symmetrically arranged, the connecting piece A401 and the connecting piece B402 can be fixed by adopting connecting modes such as riveting, and connecting pieces are arranged on the connecting piece A401 and the connecting piece B402.

The specific connection structure among the joint A2, the connecting piece 4 and the joint B5 is as follows: the two vertical sides of the connector A2 are in running fit with the upper end connecting sheet of the connecting piece 4 through the first fixing piece 3, preferably, the two vertical sides of the connector A2 clamp the upper end connecting sheet of the connecting piece 4 and then are connected through the first fixing piece 3, the first fixing piece 3 is a screw and nut fixing piece or a riveting fixing piece, and therefore the connector A2 can rotate by taking the first fixing piece 3 as a rotating shaft; the two vertical sides of the connector B5 are rotatably engaged with the lower end connecting piece of the connecting piece 4 by the second fixing piece 7, preferably, the two vertical sides of the connector B5 are connected by the second fixing piece 7 after clamping the lower end connecting piece of the connecting piece 4, the first fixing piece 3 is a screw and nut fixing piece or a riveting fixing piece, and thus the connector B5 can rotate by using the second fixing piece 7 as a rotating shaft.

The concrete connection structures between the external connector A1 and the external connector B6 and the joints A2 and B5 are as follows: connect A2) to fixedly set up outer joint A1 on the horizontal limit, connect B5 to fixedly set up outer joint B6 on the horizontal limit, the aforesaid fixed mode of setting can be for riveting, makes things convenient for the installation dismantlement of external piece A1 and external piece B6.

In order to realize multi-dimensional rotation between the external connector A1 and the external connector B6, the projection of the first fixing piece 3 and the projection of the second fixing piece 7 are vertical, so that the rotation planes of the external connector A1 and the external connector B6 are vertical.

The utility model discloses not being restricted to and being applied to pickup, inspection mirror, also can be applied with the usefulness that turns to of other instruments.
