Wherein, two centre gripping bodies 1 can be for symmetrical setting, also can be asymmetric setting. For example, when the clamping force that needs is less, when the tight requirement of clamp is not high, two centre gripping bodies 1 do not necessarily need to be exactly the same, as long as two relative arcwall faces can draw close under the action of gravity, the tight instrument that needs to accomodate of clamp according to the action of gravity can. In order to ensure stable clamping, the weight of the two clamping bodies 1 may also be approximately the same.

In this embodiment, the fixing manner and the fixing position of the tool holder are not limited, and the tool holder may be movably connected or fixedly connected. For example, the clamping device can be fixed on a wall surface through a connecting shaft, a through hole matched with the connecting shaft is formed in the clamping body 1, the clamping body 1 is sleeved on the connecting shaft, and the other end of the connecting shaft is connected with the wall surface. The rotation center is the through hole at this time, so that the clamping body 1 can rotate around the connecting shaft. For example, the rack can be connected with the rack through a connecting shaft. The commodity shelf is provided with a through hole matched with the connecting shaft, one end of the connecting shaft is connected with the clamping body 1, the other end of the connecting shaft penetrates through the through hole and is connected with an additional fixing piece, so that the connecting shaft can rotate in the through hole of the commodity shelf, the clamping body 1 is further driven to rotate, and the rotating center is arranged at the position where the clamping body 1 is connected with the connecting shaft.

When needing to press from both sides tightly, the arcwall face that draws close the instrument clamp with the instrument up lifts, and the centre gripping space can be opened this moment, when the instrument is in the instrument clamp centre, and down transferring, the arcwall face can be immediately close to and firmly clip the instrument.

Example 2

As a preferred embodiment of the present invention, the present invention includes a tool holder, which comprises two symmetrical holding bodies 1. The opposite sides of the two clamping bodies 1 are arc-shaped surfaces, and friction surfaces 2 used for increasing friction are further arranged on the arc-shaped surfaces of the clamping bodies 1. The centers of gravity of the two clamping bodies 1 are both close to the arc-shaped surface. The clamping body 1 can rotate up and down in a vertical plane, and the rotating center is far away from the arc-shaped surface, so that clamping spaces with different intervals are formed.

Example 3

As another preferred embodiment of the present invention, the present invention includes a tool holder, which comprises two holding bodies 1 and two mutually engaging synchronizing gears 6. The two clamping bodies 1 are respectively connected with a synchronous gear 6 through a rotary connecting shaft 3.
