In the micro sample clamping device, one of the forceps handles is provided with a mounting hole, the mounting hole is formed at the movable end close to the one of the forceps handles, and the limiting part is mounted on the mounting hole.

The micro sample clamping device as described above, wherein the stopper comprises: the screw bolt is arranged on the mounting hole, one screw nut is sleeved on one end of the screw bolt, and the other screw nut is sleeved on the other end of the screw bolt.

In the above micro sample gripping device, the plurality of elastic members are: and the four springs are respectively arranged on the opposite side surfaces of the two forceps handles close to each other in pairs.

In the above micro sample gripping device, the plurality of elastic members are: and the four rubber balls are respectively arranged on the opposite side surfaces of the two forceps handles close to each other in pairs.

In the micro sample clamping device, the elastic member is mounted at one end far away from the fixed ends of the two forceps handles.

Compared with the prior art, the technical scheme has the positive effects that:

the utility model relates to a device is got to small sample clamp provides a controllable clamp of dynamics and gets device, through the distance between two tweezers handles of locating part control to the dynamics size of device is got to the control clamp, and the elastic component is getting the in-process and can guarantee article atress gradually, prevents that the chip from damaging, practices thrift economic cost.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

The structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention does not have the substantial technical significance, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the efficacy that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

According to fig. 1, a tiny sample gripping device comprises:

one end of each forceps handle 1 is fixedly connected with the other end of each forceps handle 1, the other end of each forceps handle 1 is operatively close to or far away from the other end of each forceps handle 1, and the other end of each forceps handle is operatively movable; the limiting piece is arranged on one forceps handle 1 and can limit the distance between the two forceps handles 1 which are close to each other in an operation mode; the elastic pieces are respectively arranged on the opposite side surfaces of the two forceps handles 1 which are close to each other; two forceps points 2, one end of each forceps point 2 is respectively connected with a plurality of elastic pieces, and the other end of each forceps point 2 can be close to or far away from each other.

In the actual use process, the hand is held on the forceps handles 1, the forceps tips 2 are close to the chip, the hand applies force to the forceps handles 1, the movable ends of the two forceps handles 1 are close to each other, the two forceps handles 1 drive the elastic pieces to be close to each other, when the elastic pieces on the two forceps handles 1 are close to the stress, the elastic pieces can drive the two forceps tips 2 to be slowly close to each other until the chip is clamped under the action of elasticity, the elastic pieces are arranged between the two forceps handles 1 and the two forceps tips 2 to limit the two forceps tips 2 not to directly receive a large force to clamp the chip, a limiting part is arranged on one forceps handle, when the stress on the two forceps handles 1 is too large, the limiting part supports the inner sides of the two forceps handles 1 to be close to each other, the stress on the chip is stopped, the stress of the chip is kept at a certain value, and the chip cannot be clamped too hard to break.
