A lead pulling mechanism and a lead clamping mechanism are arranged in the tip sleeve; a chuck unloosing mechanism and a pencil lead guiding mechanism are arranged in the pencil rod; the lead pulling mechanism is formed by assembling a lead pulling spring, a lead protecting pipe, a buffer and a retaining ring; the lead clamping mechanism is formed by assembling a clamping piece, a lock ring, a steel ball, a movement spring and a lock ring seat; the lead clamping mechanism has the function of controlling a pencil lead to move in a single direction; the chuck unloosing mechanism is formed by assembling a return spring, a side button and a press rod; when the side button is pushed, the clamping piece loosens, and then the pencil lead can move back and forth, so as to achieve the functions of feeding and withdrawing the lead; when the side button is unloosed, the press rod separates from the clamping piece, thereby having the function of clamping the lead and automatically compensating for lead extension; the pencil lead guiding mechanism is formed by assembling a guiding pipe and a guiding seat; and the lead protecting pipe, the buffer, the clamping piece, the press rod, the guiding pipe and the guiding seat are assembled in sequence and form the inner cavity in which the pencil lead is arranged.

Description

Full automatic pencil
Technical field
The utility model relates to full automatic pencil, relates in particular to press, and can compensate the full automatic pencil of the lead for retractable pencil that is worn in writing automatically.
Background technology
The general activity pencil that provides in the market, though thin lead for retractable pencil is non-sharpenning, many lead for retractable pencils of internal memory can be pressed knockout, want normal pressing when writing, and lead for retractable pencil is exposed, just can write, the too many easily broken core of knockout.Although have be improved to side by with the whipping knockout, just convenient, do not have basic solution.Propelling pencil bans the use of in primary school one, a lot of schools of second grade, because the pupil is very good moving, and propelling pencil is too movable, and pen is often dismounted badly, and influence study is so be main with Wood-bar pencil still.
Full-automatic propelling pencil, be called full automatic pencil again, when it can be write without pressing, can compensate lead for retractable pencil automatically, the internal memory core of general activity pencil being arranged again and press the knockout function, be propelling pencil of new generation, but it does not jump out general activity pencil notion, many people also are used as the general activity pencil and use, and press to press head and expose lead for retractable pencil and write.Add processed complex, the precision height can not can be produced greatly always, and is also few on the market.
Full automatic pencil also claims simple and easy full automatic pencil, and its outstanding automatic compensation function removes and presses knockout, internal memory core function, be different from the general activity pencil fully, similar Wood-bar pencil, it can only be write, and can not press, can not tear open, the lead for retractable pencil core that can not break in nib exempts from again to cut, and is easy to use.The simple and easy full automatic pencil product in Taiwan pin in the sixth of the twelve Earthly Branches about ten years, but simple and easy full automatic pencil in the past has certain deficiency, the ZL90210687.2 patent is the plain type full automatic pencil, and it has only the sandwich and the automatic function of compensation knockout, once uses up with the lead for retractable pencil of a long 120mm.But it is very inconvenient that this pen adds core, and can only knockout, can not return.Insufficiency is so market sales volume is little always.
Summary of the invention
The utility model transmission mechanism technical problem to be solved is the present situation at prior art, and a kind of full automatic pencil that has sandwich and compensate out cored structure automatically is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: full automatic pencil, comprise that equipped mutually point overlaps and have the penholder of inner chamber, wherein: be provided with core pulling mechanism and sandwich mechanism in the point cover, be provided with loose chuck mechanism and lead for retractable pencil guiding mechanism in the penholder; Core spring, retaining core pipe, damping and back-up ring are equipped to be formed core pulling mechanism by drawing; Sandwich mechanism forms by intermediate plate, retainer, steel ball, movement spring and retainer seat are equipped; Sandwich mechanism has control lead for retractable pencil one-way movement function, and when lead for retractable pencil retreated, intermediate plate was embraced lead for retractable pencil, because steel ball and retainer ramp effect do not make lead for retractable pencil retreat, when drawing core forward, steel ball can unclamp at once, makes intermediate plate unclamp lead for retractable pencil, and lead for retractable pencil can realize replenishing lead for retractable pencil forward; The pine chuck mechanism is by replying spring, side button and pressing that bar is equipped to be formed; Press the side button, intermediate plate is unclamped, lead for retractable pencil just can seesaw, and reaches to add core and move back the core function.Decontrol the side button, press bar and intermediate plate and break away from, have the function of sandwich and automatic compensation knockout; The lead for retractable pencil guiding mechanism is equipped with by guide pipe and guide holder to be formed; It is inclined to one side to guarantee that lead for retractable pencil heads into Shi Buhui; Retaining core pipe, damping, intermediate plate are pressed the inner chamber that bar, guide pipe and guide holder were equipped with and constituted built-in lead for retractable pencil in proper order.
