Description

Portable extension type book clamp

Technical field

The utility model relates to a kind of portable extension type book clamp, belongs to study article field.

Background technology

At present, student generally adopts book end to press from both sides book, but traditional book end enabling capabilities is limited, in the time that the book on classmates' table is too much, easily occur that book tilts or clamping phenomenon incessantly, causing book heap to be toppled over even drops to the ground, use extremely inconvenience, and traditional book end is generally made up of the clamping plate of two splits, in the time of carrying book, book and book end together cannot be carried to operation inconvenience.

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of reasonable in design is provided, book clamp can be held to the firm and convenient portable extension type book clamp that book entirety is carried.

Portable extension type book clamp described in the utility model, comprise casing, push rod, push pedal and lift-pull handle, before casing, rear both sides all arrange transparent window, push rod is by rotating handle, middle part screw mandrel and Elastic buckle successively one are formed by connecting, a left side for casing, right both sides arrange screwed hole, two push pedals are vertically arranged in casing, push rod setting corresponding to push pedal, push rod penetrates casing from outside, its rotating handle is positioned at outside casing, middle part screw mandrel is threaded with screwed hole, corresponding Elastic buckle arranges the draw-in groove of outer narrow inner width on the outer face of push pedal, Elastic buckle is arranged in draw-in groove, before casing, rear two upper lateral parts are also provided with installing hole, lift-pull handle is arranged in installing hole.

In this portable extension type book clamp, because middle part screw mandrel is threaded with the screwed hole on casing and the Elastic buckle of push rod is arranged in the draw-in groove of push pedal, therefore the spinning movement of rotating handle can be changed into the horizontal displacement of push rod, by the rotating handle on rotating push rod, can realize moving left and right of push pedal, thereby regulate the clamping degree of book; Elastic buckle on push rod is conventional attainable structure, can realize the quick assembling of push rod and push pedal by Elastic buckle.

When use, book is placed in casing between two push pedals, and by the rotating handle of rotation both sides drive push rod to the inside (near casing side) mobile, thereby book clamp is held firm, easy for operation and can effectively prevent book inclination or topple over; Need to get book time, drive push rod slightly to move laterally by rotating handle, and observe the position of got book by transparent window, book is taken out.Except above-mentioned points, because push pedal and book are all arranged in casing, therefore, in the time that needs are carried books, the lift-pull handle on can direct portable casing, together carries book inner with it book clamp described in the utility model, swift and convenient to operate.

In order conveniently to get book, can adopt the preferred version of casing open topped.

The beneficial effect that the utility model compared with prior art had is:

This portable extension type book clamp is simple in structure, reasonable in design, it is firm book clamp can be held by this book clamp, easy to use and can effectively prevent book tilt or topple over, in the time that needs are carried books, can directly the book entirety of book clamp and book clamp inside be carried, swift and convenient to operate.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is cutaway view of the present utility model.

In figure: 1, rotating handle; 2, middle part screw mandrel; 3, push pedal; 4, casing; 5, lift-pull handle; 6, transparent window; 7, Elastic buckle.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As Fig. 1, shown in 2, this portable extension type book clamp comprises casing 4, push rod, push pedal 3 and lift-pull handle 5, before casing 4, rear both sides all arrange transparent window 6, push rod is by rotating handle 1, middle part screw mandrel 2 and Elastic buckle 7 successively one are formed by connecting, a left side for casing 4, right both sides arrange screwed hole, two push pedals 3 are vertically arranged in casing 4, push rod setting corresponding to push pedal 3, push rod penetrates casing 4 from outside, its rotating handle 1 is positioned at outside casing 4, middle part screw mandrel 2 is threaded with screwed hole, corresponding Elastic buckle 7 arranges the draw-in groove of outer narrow inner width on the outer face of push pedal 3, Elastic buckle 7 is arranged in draw-in groove, before casing 4, rear two upper lateral parts are also provided with installing hole, lift-pull handle 5 is arranged in installing hole, be provided with in the present embodiment a pair of lift-pull handle 5, in the time of portable book clamp, can keep overall book clamp steady.

In this portable extension type book clamp, because middle part screw mandrel 2 is threaded with the screwed hole on casing 4 and the Elastic buckle 7 of push rod is arranged in the draw-in groove of push pedal 3, therefore the spinning movement of rotating handle 1 can be changed into the horizontal displacement of push rod, by the rotating handle 1 on rotating push rod, can realize moving left and right of push pedal 3, thereby regulate the clamping degree of book; Elastic buckle 7 on push rod is conventional attainable structure, adopts the buckle structure of plastic rivet in the present embodiment, as shown in Figure 2, can realize the quick assembling of push rod and push pedal 3 by Elastic buckle 7.

When use, book is placed in casing 4 between two push pedals 3, and by the rotating handle 1 of rotation both sides drive push rod to the inside (near casing side) mobile, thereby book clamp is held firm, easy for operation and can effectively prevent book inclination or topple over; Need to get book time, drive push rod slightly to move laterally by rotating handle 1, and observe the position of the book of getting by transparent window 6, book is taken out.Except above-mentioned points, because push pedal 3 and book are all arranged in casing 4, therefore, in the time that needs are carried books, the lift-pull handle 5 on can direct portable casing 4, together carries book inner with it book clamp described in the utility model, swift and convenient to operate.In order conveniently to get book, in the present embodiment, adopt the scheme of casing 4 open topped.

Certainly, the effect of this book clamp is not limited only to press from both sides book, in the time of carrying case or other texts, can adopt this book clamp, convenient in carrying.
