Book clamp with telescopic lever parts

Abstract

The invention relates to office supplies, in particular to a book clamp with telescopic lever parts. The book clamp comprises the two lever parts made of iron wires and a clamping part. The clamping part is provided with inserting holes. The lever parts are provided with free ends stretching outwards. A hand pinching end is arranged on the other side of each lever part. The free ends are insertedin the inserting holes for hinged connection, and the length of the lever parts is larger than that of the clamping part. The book clamp is characterized in that the lever parts are in a U shape, andthe two sides of each U-shaped lever part are provided with parallel telescopic rods with telescopic components; the telescopic components are drawing rod components, and when the telescopic rods contract back, the length of the lever parts is equal to the length of the clamping part; and the book clamp has the beneficial effects that page overturning is convenient, and damage to paper through thehand pinching ends is reduced.

Description

Technical field [0001] The present invention relates to office supplies, in particular to book holders. Background technique [0002] The book holder includes two lever parts made of iron wire and a clamping part. The clamping part is an elastic part made by bending an iron sheet. The clamping part is closed in a free state, and the clamping part has an insert Hole, the lever part has two free ends protruding outwards. On the other side of the lever part is the pinch end. The free end is inserted into the insertion hole and hingedly connected. The lever part functions as a lever. The length of the lever part is longer than the clamp The length of the holding part, fingers squeeze the pinching end of the lever part, you can pry open the clamping part, and then loosen the lever part, the clamping part is closed, to achieve the purpose of use; in the prior art, the two lever parts The length will not change, such as figure 1 As shown, the length from the free end to the pinching en...

Problems solved by technology

[0002] The book holder includes two lever parts and a clamping part made of iron wire. The clamping part is an elastic part bent from an iron sheet. The clamping part is closed in a free state, and the clamping part has an insertion The lever part has two free ends protruding outwards. On the other side of the lever part is a pinch end. The free end is inserted into the insertion hole to be hingedly connected. The lever part plays the role of a lever, and the length of the lever part is longer than that of the clip The length of the holding part, the finger squeezes the hand pinch end of the lever part, the clamping part can be pried open, and then the lever part is released, and the clamping part is closed to achieve the purpose of use; in the prior art, the two lever parts The length will not change, such as figure 1 As shown, that is, the length from the free end to the pinch end is constant, because the length of the lever part is greater than the length of the clamping part, the lever part exceeds the outside of the clamping part, so the lever part hinders the page turning of the paper, especially When the book holder holds a stack of papers, when only a few pages are turned over, the hand-pinch end of the lever part of the book holder is easy to poke the first few pages, which has the disadvantage of being inconvenient to use
