Abstract

The utility model relates to a pair of fetching and putting tongs for an optical disk. The utility model comprises an upper tong body at the other side of an upper tong handle, an upper jaw which is arranged at the front end of the upper tong body, a tabular lower tong body which is arranged at the other side of a lower tong handle and a lower jaw which is arranged at the front end of the lower tong body, wherein the upper tong handle and the lower tong handle are connected and form a running fit by a small shaft and a small torsional spring, and the upper tong body is rectangular and tabular; the upper jaw is downwards bent; the lower jaw is inwards concave. The tongs are moved to a position for fetching the optical disk, the tong handles are depressed, the small torsional spring is compressed, the tong bodies are spread, the upper tong body is horizontally attached to the back of the optical disk, the upper jaw is attached to the edge of an inner hole of the optical disk, the lower tong handle is loosened, the lower jaw is attached to an outer circle of the optical disk for clamping the optical disk, when the tongs are moved to a proper position, the optical disk is put down. The utility model can avoid the defilement of the optical disk because of hand contact, and compared with hands, the utility model is more convenient for fetching and putting the optical disk.

Description

Fetching and putting clippers for optical disk

The utility model relates to a kind of clip.

In the prior art field; the use of CD is frequent day by day; owing to be not exclusively used in the instrument that pipettes CD usually; can only directly grasp with hand; especially in the CD server of associating, get dish replacing posture and put into CD-ROM drive; this process usually can be stayed finger mark on CD, so that produces stained CD in the future, and What is more, and foreign matter scratches CD.

The purpose of this utility model is to design a kind of Fetching and putting clippers for optical disk that CD conveniently can not scratch CD that picks and places.

In order to achieve the above object, the technical solution adopted in the utility model is: upper plier handle and lower plier handle have the little axle of little torsion spring to connect to form normal-running fit with string, one end of little torsion spring withstands on below the upper plier handle, its other end withstands on above the lower plier handle, the opposite side of upper plier handle is the upper clamp of right angle sheet, the upper clamp front end is reclinate upper jaw, and the opposite side of lower plier handle is the lower clamp of sheet, and the lower clamp front end is the lower jaw that concaves.

Description of drawings:

Fig. 1 is an assembling scheme drawing of the present utility model;

Fig. 2 is a structural representation of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing.As shown in Figure 1 and Figure 2, upper plier handle 1 and lower plier handle 4 usefulness string have the little axle 3 of little torsion spring 2 to connect to form normal-running fit, one end of little torsion spring 2 withstands on below the upper plier handle 1, its other end withstands on above the lower plier handle 4, the opposite side of upper plier handle 1 is the upper clamp 7 of right angle sheet, upper clamp 7 front ends are reclinate upper jaws 8, and the opposite side of lower plier handle 4 is lower clamps 5 of sheet, and lower clamp 5 front ends are the lower jaws 6 that concave.

As shown in Figure 1 and Figure 2, the radius of curvature of upper jaw 8 is identical with CD 9 endoporus radiuss of curvature, and upper clamp 7 is parallel to the length of a long square edge of CD 9 near the length of bore edges in the CD 9 to CD 9 cylindricals; The radius of curvature that lower jaw 6 concaves is identical with CD 9 cylindrical radiuss of curvature, and the length of lower clamp 5 is near length and the CD 9 thickness sums of upper clamp 7 perpendicular to a short square edge of CD 9.

Because the front of CD can not directly be subjected to the extruding of external force foreign matter, thereby the point of application of Fetching and putting clippers for optical disk is arranged on bore edges and CD outer circular edge in the CD.Consider the comfort level of hand when picking and placeing CD simultaneously, whole gripper design becomes the crank-like structure.Sometimes directly from the CD storage case, take out when getting dish, upper clamp 7 is made thin metal construction, and the outside face plastic-blasting of pliers is handled, in case hard thing stays cut at optical disc surface; Lower jaw length is greater than upper jaw, vises stability behind the CD with increase.

During operation, pliers moved on to wait to get the CD place, pin lower plier handle 4, compress little torsion spring 2, lower clamp 5 is opened, upper clamp 7 is smooth in the CD back side, upper jaw 8 by chance is attached to bore edges in the CD, unclamp lower plier handle 4, the elastic force effect of little torsion spring 2 is attached on the cylindrical of CD the lower jaw 6 of lower clamp 5 front ends and vises CD firmly, can be at random with the suitable place of pincers moving CD.Repeating above-mentioned action sells at reduced prices and gets dish.

The useful effect that the utlity model has is: adopt this Fetching and putting clippers for optical disk to pick and place CD, can avoid because of Hand contacts CD and may cause stained CD, picks and places CD than picking and placeing CD more with hand in CD seasoning case For convenient.
