Abstract

The utility model discloses a pushing type automatic pencil which comprises a nib 1 and a holder 8, wherein a lead piercing hole 2 is arranged in the nib 1. A lead sending propeller 5 is arranged in the pen holder 8, a lead clamping mouth 11 is arranged in the head of the lead sending propeller 5, and a clamp ring 12 is arranged outside the lead sending propeller 5. The outside the body of the lead sending propeller 5 is provided with a spring 6 and sheathed with a lead holding propeller 7 which is connected with the spring 6, the lead holding propeller 7 is sheathed with a main propeller 9 extending out of the holder 8, and positioning devices 3 are arranged outside the clamp ring 12, on the inner wall of the holder and on the inner wall of the lead piercing hole 2 on the nib, and are connected to the spring 6. The front ends of the positioning devices 3 and the lead piercing hole 2 of the nib are provided with vibration preventing erasers 4, and steps 10 are arranged on the positioning device 3 and on the inner wall of the holder near the nib. The utility model effectively solves the problem that the prime lead can not be easily pushed out, and has the advantages of free entrance and shrinkage of the lead, clamping prevention, vibration prevention and convenient use.

Description

The push type automatic pencil

One, technical field

The utility model relates to the pencil that a kind of daily life is used, and particularly relates to a kind of propelling pencil.

Two, background technology

Existing propelling pencil is to utilize push rod that the pen core in the extruded tube is extruded nib, can occur old-fashioned snap ring in the former penholder unavoidably by the phenomenon that the penholder inwall blocks in progradation, causes pen core not to be pushed out, and this uses comparatively inconvenience.

Three, utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, can make that pen core is released smoothly, push type automatic pencil easy to use and provide a kind of.

The purpose of this utility model realizes by following technical solution: a kind of push type automatic pencil, comprise nib, penholder, be provided with lead-filling hole in the nib, in described penholder, be equipped with and send the pen core propeller, send and be provided with pen clip core mouth in the angle of rake head of pen core, it outer is equipped with collar, send and outside the angle of rake body of the pen core portion spring is housed and is with dress pen core propeller, dress pen core propeller links with spring again, dress pen core propeller is with main thruster outward again, and main thruster stretches out outside the penholder again; Outside described collar, the lead-filling hole inwall of penholder inwall and described nib is provided with locator, locator links with spring again, at the front end of locator, the lead-filling hole place of nib vibration-stopper gum is housed, and on locator, the penholder inwall is provided with step near the nib place.

After adopting the utility model structure, only need firmly advance main thruster, and promotion dress pen core propeller, impel and send the pen core propeller to advance, when collar blocks pen clip core mouth clamping pen core and delivers to the step place of locator, collar is blocked by step and halts, and send the pen core propeller to move on and pen core is delivered to the lead-filling hole of nib this moment.Because the front end of locator and vibration-stopper gum be to the location and the clamping action of pen core, and send the angle of rake pen clip core of the pen core temporary transient releasing orientation that mouth has, pen core can be released smoothly.Therefore, the utility model compared with prior art has pen core advance to contract freedom, anti-sticking advantage shockproof, easy to use.

Four, description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model push type automatic pencil.

Five, the specific embodiment

With reference to Fig. 1 as can be known, the utility model push type automatic pencil, comprise nib 1, penholder 8, be provided with lead-filling hole 2 in the nib 1, in described penholder 8, be equipped with and send pen core propeller 5, send and be provided with pen clip core mouth 11, its outer collar 12 that is equipped with in the head of pen core propeller 5, send and outside the body portion of pen core propeller 5 spring 6 (this spring does not contact with sending the pen core propeller) is housed and is with dress pen core propeller 7, dress pen core propeller 7 links with spring 6 again, be with main thruster 9 again outside the dress pen core propeller 7, main thruster 9 stretches out again outside the penholder 8; Outside described collar 12, lead-filling hole 2 inwalls of penholder inwall and described nib are provided with locator 3, locator 3 again and spring 6 link (being that locator is located at the position between the penholder inwall from the lead-filling hole inwall to the spring front end), at the front end of locator 3, lead-filling hole 2 places of nib vibration-stopper gum 4 is housed, and on locator 3, the penholder inwall is provided with step 10 near the nib place.Can be between the locator that wherein is located at lead-filling hole inwall place and the nib for being threaded, screwing off nib can separate nib with locator; Vibration-stopper gum 4 has clamping pen core and shockproof double action; The front portion of penholder can be with rubber 14, and its afterbody can be with pen clip 15.In order to make the utility model use the rubber scrape along to prevent coming off of erasing rubber more easily, described dress pen core propeller 7 can be with main thruster 9 and is threaded, and in the main thruster 9 erasing rubber 13 is housed.When using erasing rubber, inwardly the precession main thruster exposes erasing rubber; When not using erasing rubber, outwards screw out main thruster and cover erasing rubber.

Operation principle of the present utility model is: the pen core propeller and be pushed into and send the angle of rake pen clip core of pen core mouth place of earlier pen core being packed into, firmly advance main thruster then, and promotion dress pen core propeller, impel and send the pen core propeller to advance, when collar blocks pen clip core mouth clamping pen core and delivers to the step place of locator, collar is blocked by step and halts, send the pen core propeller to move on and pen core is delivered to the lead-filling hole of nib this moment, because the front end of locator and vibration-stopper gum are to the location and the clamping action of pen core, pen core stretches out nib by lead-filling hole, and send the angle of rake pen clip core of pen core mouth this moment is releasing orientation.Decontrol main thruster again, because the return action of spring, when sending the pen core propeller to be retracted into the step place, collar blocks pen clip core mouth again again and returns original position and pen core is clamped.When needs are removed this propelling pencil, screw off nib earlier, firmly main thruster is outwards pulled out again, thus dress pen core propeller, send pen core propeller and spring, locator also can be along with pulling out outside the penholder.The utility model all can use for cuboid, cylinder pen core.
