The first guiding slideway 5 can adopt a conventional sliding rail structure, and the sliding structure of the positioning base 3 on the first guiding slideway 5 is also conventional technology, and will not be described in detail here.
The positioning member 6 is adapted to fit into a positioning notch on the target device 9, and may be a positioning pin, such as a taper pin, a cylindrical pin, or a wedge pin.
Furthermore, the positioning ball 4 is installed on the positioning base 3 and the positioning ball and the positioning base 3 form a ball hinge pair, accordingly, the positioning base 3 forms a ball seat of the ball hinge pair, a ball bowl is arranged on the positioning base 3, and the positioning ball 4 is installed in the ball bowl to form a ball hinge pair.
Further, as shown in fig. 1-6, a bearing and driving groove for the double-sided wedge block 1 to extend into is formed in the positioning ball 4, the bearing and driving groove has two bearing and driving surfaces sequentially arranged along the sliding direction of the positioning base 3, and the two bearing and driving surfaces are inclined surfaces having an included angle with the sliding direction of the positioning base 3. Obviously, the two bearing and driving surfaces are used for being respectively matched with the two wedge surfaces of the double-sided wedge block 1 to achieve the purpose of switching the operation of the positioning piece 6 between the locking position and the unlocking position, wherein one of the two bearing and driving surfaces is a locking bearing and driving surface for enabling the positioning piece 6 to operate to the locking position, and the other bearing and driving surface is an unlocking bearing and driving surface for enabling the positioning piece 6 to operate to the unlocking position; two wedge surfaces of the double-sided wedge block 1 are correspondingly a locking wedge surface and an unlocking wedge surface; the two bearing and driving surfaces can be in a parallel relationship, but are preferably parallel to each other, so that the state switching of the positioning element 6 can be realized in multiple cycles; in addition, preferably, the locking driving bearing surface is parallel to the locking wedge surface, and the unlocking driving bearing surface is parallel to the unlocking wedge surface, and certainly, based on the positioning ball 4 hinged to the positioning base 3, the positioning ball has a universal movement characteristic, so that in an initial state, when the locking driving bearing surface is not parallel to the locking wedge surface/the unlocking driving bearing surface is not parallel to the unlocking wedge surface, after the double-sided wedge block 1 contacts the positioning ball 4, the positioning ball 4 can adaptively enable the locking driving bearing surface to be parallel to the locking wedge surface/the unlocking driving bearing surface to be parallel to the unlocking wedge surface.
