Abstract
The utility model discloses a propelling pencil which comprises a pencil holder and a pencil point which is connected with the pencil holder. The top part of the pencil holder is provided with a movable button, a core storing tube is arranged in the pencil holder and a core protecting tube is arranged in the pencil point. A damping element is arranged in the core protecting tube, an opening is arranged at the head part of the pencil point and a lead cord is penetrated through the damping element and the core protecting tube and is extended out of the opening. The utility model is characterized in that a core protecting tube seat is arranged in the pencil point, the core protecting tube is movable and is made of plastics and a core expanding tube is provided with a positioning boss. A pressing spring of the core protecting tube is arranged between the core protecting tube seat and the positioning boss, a clamping head is arranged at the front part of the core storing tube and a pushing and pulling sleeve is arranged at the out side of the clamping head in a coaxial way. The tail part of the clamping head is provided with a convex circle, a pressing spring of a machine core is arranged between the convex circle and the end surface of the pushing and pulling sleeve and steel balls are arranged between the clamping head and the radial surface of the pushing and pulling sleeve. The front part of the pushing and pulling sleeve is provided with a tapered opening, wherein the front part of which is large and the back part of which is small and the back part of the core protecting tube and the front part of the pushing and pulling sleeve are provided with gaps. The utility model has the advantages that the writing time of the lead cord can be extended after the lead cord is supplied one time, the lead cord is not easy to be broken off and the utility model can be used more conveniently.
Description
Technical field
The utility model relates to a kind of pencil, especially relates to a kind of propelling pencil.
Background technology
Existing propelling pencil comprises penholder and the nib that links to each other with penholder, and the top of penholder is provided with active button, is provided with the lead for retractable pencil feed mechanism in the penholder, and the head of nib is provided with opening, and the nib inwall is provided with fixedly rubber damping spare.Its operation principle is the pressing active button, and the lead for retractable pencil that the lead for retractable pencil feed mechanism comes out passes damping piece to the nib head, and keeps certain length at the nib head, provides people to write with this.Conventional propelling pencil, knockout length of every pressing be 0.4～1.2, in case need pressing again after exposing the lead for retractable pencil of retaining core pipe and having write, long as knockout, then the lead for retractable pencil owing to propelling pencil is thinner, and lead for retractable pencil easily fractures.And lead for retractable pencil is exposed shorter, and then short lead for retractable pencil can only be kept short writing time, must press button regularly and finish knockout and guarantee to write needs, uses very inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of propelling pencil at above-mentioned prior art present situation, and it can prolong writing time as much as possible after once supplying with lead for retractable pencil, and frangibility not, uses convenient.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of propelling pencil, comprise penholder and the nib that links to each other with described penholder, described penholder top is provided with active button, be provided with core storage tube in the described penholder, be provided with retaining core pipe in the described nib, be provided with damping piece in the described retaining core pipe, the head of described nib is provided with opening, lead for retractable pencil passes described damping piece and described retaining core pipe stretches out described opening, it is characterized in that being provided with in the described nib retaining core pipe seat, described retaining core pipe is the movable retaining core pipes of plastics, described retaining core pipe is sent out and is equipped with positioning boss, be provided with the retaining core pipe stage clip between described retaining core pipe seat and the described positioning boss, the front portion of described core storage tube is provided with dop, described dop is coaxially arranged with outward to push away and pulls out cover, the afterbody of described dop is provided with dome, described dome and described pushing away are provided with the movement stage clip between the end face that pulls out cover, described dop and described pushing away between the sagittal plane that pulls out cover are provided with steel ball, the described front portion of pulling out cover that pushes away is provided with pre-large post-small tapered opening, and the rearward end of described retaining core pipe and the described front portion of pulling out cover that pushes away are provided with the gap.
The outside of the head of described retaining core pipe is tapered.
Described clearance distance is less than the length of the described retaining core pipe part of exposing described nib.
Compared with prior art, advantage of the present utility model is to enter after the retaining core pipe when a lead for retractable pencil, push away and pull out cover and clamp dop by steel ball lead for retractable pencil is fixed, and along with the carrying out of writing, movable retaining core pipe progressively moves backward, when socket is pulled out after touch with pushing away in the rear end of retaining core pipe, will drive when continuing to write to push away and pull out cover and move backward, when steel ball enters tapered opening, dop will loosen the fixed clamp to lead for retractable pencil, the retaining core pipe of activity this moment will drive lead for retractable pencil and move forward under the effect of retaining core pipe stage clip, so constantly repeat, we just can write always when therefore using, till a lead for retractable pencil is used up, press cap and need only pressing after lead for retractable pencil is used up, new lead for retractable pencil will enter retaining core pipe automatically; The positioning boss that is provided with on the retaining core pipe is the retaining core pipe length of stretching out nib fixedly; The outside of the head of retaining core pipe is tapered and can adopt special plastic material to make retaining core pipe, will compare in writing process along sliding and can not scratch paper; And since lead for retractable pencil always in retaining core pipe, so just effectively the protection lead for retractable pencil is normally being write continuous core under the situation, can protect lead for retractable pencil effectively; Owing to have continuous core when normally writing, can also adopt 2B lead for retractable pencil (owing to be afraid of disconnected core, generally adopting the HB lead for retractable pencil in the prior art) in the use, make write more smooth and easy, cunning.
