The book that provides a kind of tensile book to clamp to take eminence at the defective that prior art exists is provided.
The present invention for achieving the above object, adopt following technical scheme: a kind of library's book pincers of adjustable-length, comprise and rotate cross-coupled left clamp arm and right clamp arm, described tong arm lower end is equipped with length adjustment device, described length adjustment device comprises the handle inserted link that is enclosed within the tong arm lower end, described tong arm lower end sidewall is evenly equipped with some locating holes, and screw passes described locating hole and is threaded with the handle inserted link.
Preferably, the cross section of described tong arm lower end and handle inserted link upper end is ellipse.
Preferably, fixedly there is first side plate described left clamp arm upper end, corresponding second side plate that is provided with first side plate in described right clamp arm upper end, and second side plate bottom is provided with base plate.
Preferably, the length of described first side plate equals half of the second side plate length.
Beneficial effect of the present invention: need not to carry stool and wait the bed hedgehopping height, only use pliers just can easily take, deposit books from eminence; Simple in structure, easy to use, according to the difference of height, also can regulate the length of book pincers, adapt to the demand of different heights; The plate of book pincers front end is fit to the books of taking; The structure of adjusting length of book pincers adopts oval cross section, can avoid book pincers bottom to rotate.
Description of drawings
Fig. 1 structural representation of the present invention.
The specific embodiment
Figure 1 shows that a kind of library's book pincers of adjustable-length, left clamp arm 4, right clamp arm 5 are formed hinge by connecting pin 6 and are connected.Left side handle inserted link 8 is enclosed within on the left clamp arm 4, and in order to prevent relatively rotating between left handle inserted link 8 and the left clamp arm 4, the cross section of left handle inserted link 8 and left clamp arm 4 all is oval.The structure of length adjustment mechanism is as follows: the arranged outside at left clamp arm 4 has a series of locating holes 10, left handle inserted link 8 is provided with internal thread hole 11, unclamp screw 9, adjust the relative position of left clamp arm 4 and left handle inserted link 8, cooperate by screw 9 insertion locating holes 10 and with internal thread hole 11, fixedly left clamp arm 4 and left handle inserted link 8 have just been finished the adjusting of length left clamp arm 4.In like manner, right clamp arm 5 and right handle inserted link 7 also have such length adjustment mechanism.Upper fixed at right clamp arm 5 has second side plate 1 and base plate 2, and the width B of base plate 2 is about the thickness of a book.There is the length H1 of first side plate, 3, the first side plates 3 to equal half of second side plate, 1 length H2 in the upper fixed of left clamp arm 4.
Eminence is got book: during use, adjust the length of book pincers earlier according to height.Scoop up the bottom of book by the base plate 2 of right clamp arm 5 tops, second side plate 1 supports a side of book, book pincers integral body is inserted inward again, makes first side plate 3 be positioned at an other side of book, clamps book by handle, and takes off book.
Hoist and put book: the book that elder generation tightly need put with the book clamp, drop it off on the bookshelf of eminence, unclamp second side plate 1 and first side plate 3, take out the book pincers and get final product.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
