Abstract

The invention discloses a pencil clamping and placing device for student stationeries. The pencil clamping and placing device comprises a sleeve, wherein the upper end of the sleeve is provided with afixing tube, the fixing tube is screw-connected and fixed to the sleeve; the upper end of the fixing tube is provided with an adjusting device, the upper end of the adjusting device is provided witha rotary pen cap, the outer side of the rotary pen cap is provided with a placing hanging rod, and the placing hanging rod is fixedly connected with the rotary pen cap; the center of the lower end ofthe rotary pen cap is provided with a fixing plate, the right end of the center of the fixing plate is provided with a first lead screw, and the first lead screw is fixedly connected with the fixing plate. When the pencil clamping and placing device for student stationeries is used, the telescoping length of a second lead screw is adjusted by turning the rotary pen cap, the second lead screw pushes a pencil in the sleeve to change the telescoping length of the lower end of the pencil, pencil sharpening can be performed in a clamping state of a clamping cylinder when being needed, or the pencilcan also be taken down for sharpening and then is put on again for use; the telescoping length of the pencil is wholly adjusted, the pencil utilization rate is high, materials are saved, and the pencil clamping and placing device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a pencil clamping and placing device for student stationery. Background technique [0002] my country is a big producer of pencils, with an annual output of hundreds of millions and a huge amount of wood consumption. At present, the outer diameter of the commonly used wooden pencil is 7.6 millimeters, and the thin pencils with a diameter below 6 millimeters are not widely used because the hand is not firm. ) is abandoned, the waste is staggering. The thin pencil pencil is set on the clamping and placing device, so that the thin pencil can be widely used to overcome the defect that the hand is not firm, save the materials used for pencil manufacturing, and fully improve the utilization rate of the pencil. , because there is no stopper at the rear end of the clamping device, the pencil slides upwards, causing the front end of the pencil to be too short due to expansion and con...
