Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the utility model discloses a synchronous clamping structure, including bottom plate 1, cylinder 2, support plate 11 and more than one connecting rod 4, support plate 11 installs more than one linear guide 3 on the surface, linear guide 3 is the diamond structure and distributes, equal slidable mounting has slider 8 on linear guide 3, guide pillar 6 is installed perpendicularly to the center department of bottom plate 1, the middle department of connecting rod 4 all forms the collar of a circular structure, all install bearing 7 in the collar, bearing 7 all installs on guide pillar 6, connecting rod 5 is all installed through the pivot at the both ends of connecting rod 4, connecting rod 5 one end is all installed on slider 8 through the pivot, connecting rod 4 realizes the equidirectional rotation through cylinder 2, slider 8 all installs clamping jaw 9 on the surface, clamping jaw 9 realizes through connecting rod 5 that synchronous inside presss from both sides tightly or synchronous outside unclamps.

In this embodiment, the carrier plate 11 is disposed at the upper end of the bottom plate 1, the carrier plate 11 and the bottom plate 1 are disposed in parallel, more than one supporting column 10 is installed between the carrier plate 11 and the bottom plate 1, and the upper ends of the clamping jaws 9 are all bent and extend to the surface of the carrier plate 11.

In this embodiment, the cylinders 2 are two and distributed at the upper end of the bottom plate 1 in an L-shaped structure, the bottom surfaces of the cylinders 2 are all installed on the bottom plate 1, and piston rods on the cylinders 2 are respectively installed at one end of the connecting rod 4 through a rotating shaft.
