Detailed Description
For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:
as shown in fig. 1-4, comprises a first cross half buckle 1, a second cross half buckle 2 and an arc buckle 3. The first cross half buckle 1 is provided with a first arc-shaped groove 1.1 which is crossed in a cross way, and the lengths of the first arc-shaped grooves 1.1 in two vertical directions are equal. Four right angles that 1 was half detained in first cross all are equipped with first connecting portion 1.2, are equipped with first bolt hole 1.3 and second bolt hole 1.4 on first connecting portion 1.2, and first bolt hole 1.3 is closer to the right angle than second bolt hole 1.4.
The second cross half buckle 2 is provided with a second arc-shaped groove 2.1 which is crossed in a cross way, and the lengths of the second arc-shaped grooves 2.1 in two vertical directions are unequal. Four right angles of the second cross half buckle 2 are all provided with second connecting parts 2.2, and the second connecting parts 2.2 are provided with third bolt holes 2.3. The second cross half buckle 2 and the first cross half buckle 1 are buckled oppositely to form a cross round hole, gaps are formed at two ends of the shorter second arc-shaped groove 2.1, and the third bolt hole 2.3 is matched with the first bolt hole 1.3 and is connected and fixed through bolts.
