Description

It is a kind of can automatic protection pen tip appliance for holding pen and pen

Technical field

The utility model relates to schooling apparatus technical field, more particularly to it is a kind of can automatic protection pen tip appliance for holding pen and Pen.

Background technique

Child is more active, often pen lane is dropped to the ground without paying attention to, the pencil-lead just cut just is broken, very To the news for thering is pen tip to stab children often.Although someone devises the pen cap for pencil, such as gel ink pen and ball The included pen cap of pen, but this independent pen cap is frequently not to be lost for child, exactly forgets to cover, and is seldom played The due effect of pen cap.In addition, for starting the child to learn to write, in order to allow them to form the habit that correctly holds a pen, often Use appliance for holding pen.Appliance for holding pen is exactly that the pen cap of positioning is provided for thumb and index finger, when use its set on penholder, to cultivate children Virgin correct pen holding posture.But have both adjustment pen holding posture and protect pen tip appliance for holding pen substantially use it is all more troublesome, It is often difficult to play predetermined action, to reduce practicability.

Currently, related technical personnel protect to pen tip and appliance for holding pen has carried out some improvement.As number of patent application is A kind of Antibreaking pen disclosed in CN201020178328.X China utility model is realized by installing an expansion bend at pen tip Protection to pen tip, but the design structure is more complicated, manufacturing cost is higher, and is difficult to popularize.As number of patent application is Antibreaking pen disclosed in CN201620619735.7 China utility model, including annulus and the curved baffle for being set to annulus lower end, Annulus covers on penholder when use, and pen tip directly bumps against with floor when curved baffle grows pen tip to prevent pen to land, to protect Pen tip is protected, but will affect the sight of people's writing.If number of patent application is that CN201320365924.2 China utility model is public The Antibreaking pen opened has added a metal bending sheet devices by the side in pen, when use manpower can press its bending segment to Bounce metal clips, and when pen is fallen, metal clips, which can be kept off before pen tip, generates buffering effect, but easily regards to writing when writing Line impacts.If number of patent application is a kind of Multifunctional pencil grip disclosed in CN201220738762.8 China utility model, Including that can cover appliance for holding pen ontology on penholder and by holding of being connected with appliance for holding pen ontology of shaft away from fixator, when writing, is wanted It first holds and rotates through away from fixator, and fixed column thereon is connected with the fixing groove on appliance for holding pen ontology；It is needed when not writing It will hold to prop up away from fixator manually and rotate to pen tip front end, to play the role of pen cap；But the design procedure is cumbersome, is easy Child is caused to forget to cover pen cap and forget to prop up to hold away from fixator.If number of patent application is CN201620120463.6 China A kind of anti-dual-purpose appliance for holding pen of injury of positioning disclosed in utility model, including the pen cap and positioning rule, positioning rule pin and pen cap phase Even, positioning rule is used to position the height that holds a pen of appliance for holding pen；Positioning rule is withdrawn when writing and is used as a part of appliance for holding pen, no Positioning rule is opened when writing and covers pen tip, prevents student from being injured by pen tip；The design needs additional to go manually when not writing Realize the function of its pen cap, child usually can also forget.
