Description

Technical Field

[0001] This utility model relates to a mechanical pencil. Background Technology

[0002] The pencil is a basic writing tool, but traditional pencils require a sharpener, making them inconvenient to use. To solve this problem, the mechanical pencil was developed.

[0003] However, with traditional mechanical pencils, the tip of the lead is always used in one direction when writing, which causes the tip of the lead to wear in one direction. As a result, the tip of the lead still needs to be sharpened with a knife, which is still somewhat inconvenient to use. Utility Model Content

[0004] Therefore, it is necessary to provide a mechanical pencil that can solve the above problems.

[0005] A mechanical pencil includes a housing and a lead-extracting structure. The housing includes a main body sleeved outside the lead-extracting structure and a rotating component rotatably disposed on the main body. The lead-extracting structure is provided with a rotating mating component that matches the rotating component.

[0006] The rotating component rotates relative to the outer shell, thereby driving the rotating mating component to rotate, which in turn drives the core-exiting structure to rotate relative to the outer shell.

[0007] In one embodiment, the rotating element is a sleeve disposed at the end of the main body.

[0008] In one embodiment, the rotating member is provided with a rotating part, and the rotating mating member is provided with a rotating mating part that matches the rotating part. The rotating part and the rotating mating part are at least one of a groove and a protrusion, respectively.

[0009] In one embodiment, the rotating member and the rotating mating member are fitted together.

[0010] In one embodiment, the outer surface of the main body is provided with a plurality of finger pressing grooves, and the outer surface of the rotating component is provided with a plurality of strip-shaped protrusions.

[0011] In one embodiment, the rotating member is located at the tip of the mechanical pencil, and the rotating member is conical in shape.

[0012] In one embodiment, the mechanical pencil further includes a rotation direction limiting member rotatably disposed on the lead-out structure;

[0013] The outer side of the rotation direction limiting member is provided with a rotation limiting part, and the inner side of the main body is provided with a rotation limiting mating part that matches the rotation limiting part; the rotation direction limiting member is provided with a rotation direction limiting part, and the core output structure is provided with a rotation direction limiting mating part that matches the rotation direction limiting part.

[0014] When the core-ejecting structure rotates relative to the outer shell, the rotation limiting part and the rotation limiting mating part cooperate to allow the core-ejecting structure to rotate relative to the rotation limiting part. The rotation direction limiting part and the rotation direction limiting mating part allow the core-ejecting structure to rotate only in a clockwise or counterclockwise direction.

[0015] In one embodiment, both the rotation direction limiting part and the rotation direction limiting mating part are inclined teeth.

[0016] In one embodiment, the rotation direction limiting member is a sleeve fitted onto the core-exiting structure, and the rotation direction limiting part is an annular structure disposed at the end of the rotation direction limiting member.

[0017] In one embodiment, the rotation limiting part and the rotation limiting mating part are at least one of a groove and a protrusion, respectively.

[0018] When this type of mechanical pencil is in use, the lead is inserted into the lead-out mechanism. The tip of the lead is always used in one direction. After the tip of the lead wears down in one direction, the user can operate the rotating component to rotate relative to the outer shell, thereby driving the rotating mating component to rotate, which in turn drives the lead-out mechanism to rotate relative to the outer shell, and in turn drives the lead to rotate.

[0019] Compared to traditional mechanical pencils, this type of mechanical pencil allows the pencil lead to rotate, enabling the user to use the pencil lead tip in different directions while writing. This causes the pencil lead tip to wear in different directions, allowing it to remain writable for a longer period of time, making it more convenient to use. Attached Figure Description

[0025] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] Combination Figure 1 , Figure 2 and Figure 3 The present invention discloses an embodiment of a mechanical pencil, including a housing 10 and a lead-feeding structure 20. The housing 10 includes a main body 12 sleeved outside the lead-feeding structure 20 and a rotating member 14 rotatably disposed on the main body 12. The lead-feeding structure 20 is provided with a rotating fitting member 22 that matches the rotating member 14.

[0027] The rotating component 14 rotates relative to the outer shell 10, thereby driving the rotating mating component 22 to rotate, which in turn drives the core-exiting structure 20 to rotate relative to the outer shell 10.

[0028] When this mechanical pencil is in use, the pencil lead 200 is inserted into the lead-exiting structure 20. The tip of the pencil lead 200 is always used in one direction. After the tip of the pencil lead 200 wears down in one direction, the user can operate the rotating component 14 to rotate relative to the outer shell 10, thereby driving the rotating mating component 22 to rotate, which in turn drives the lead-exiting structure 20 to rotate relative to the outer shell 10, and thus drives the pencil lead 200 to rotate.

[0029] Compared to traditional mechanical pencils, this mechanical pencil allows the tip of the lead 200 to be used in different directions during writing by rotating the lead 200. This causes the tip of the lead 200 to wear in different directions, thus keeping the tip of the lead 200 in a writable state for a longer period of time, making it more convenient to use.

[0030] Preferably, in this embodiment, the rotating component 14 is a sleeve disposed at the end of the main body 12.

[0031] Combination Figure 4 In this embodiment, the rotating member 14 is provided with a rotating part 142, and the rotating mating member 22 is provided with a rotating mating part 222 that matches the rotating part 142. The rotating part 142 and the rotating mating part 222 are at least one of a groove and a protrusion, respectively.

[0032] In other embodiments, the rotating part 142 and the rotating mating part 222 can also be other structures, as long as they can cooperate with each other to drive the rotating mating part 22 to rotate when the rotating part 14 rotates.

[0033] Referring to the accompanying drawings, specifically in this embodiment, the rotating member 14 and the rotating mating member 22 are fitted together.

[0034] This structural design makes the connection between the rotating component 14 and the rotating mating component 22 more stable.

[0035] Referring to the accompanying drawings, specifically in this embodiment, the outer surface of the main body 12 is provided with a plurality of finger pressing grooves 122, and the outer surface of the rotating component 14 is provided with a plurality of strip-shaped protrusions 144.

[0036] The finger pressing groove 122 can help position the pen and correct the pen grip posture, while the strip-shaped protrusion 144 can increase friction, allowing the user to better operate the rotating part 14.

[0037] Specifically, in this embodiment, the rotating member 14 is located at the tip of the mechanical pencil, and the rotating member 14 is conical in shape.

[0038] At this point, the rotating part 14 is actually the pen tip part of the outer casing 10.

[0039] In other embodiments, the rotating member 14 may also be other parts of the housing 10.

[0040] Referring to the accompanying drawings, preferably, the mechanical pencil also includes a rotation direction limiting member 30 rotatably disposed on the lead-out structure 20.

[0041] Specifically, the outer side of the rotation direction limiting member 30 is provided with a rotation limiting part 32, and the inner side of the main body 12 is provided with a rotation limiting mating part 124 that matches the rotation limiting part 32. The rotation direction limiting member 30 is provided with a rotation direction limiting part 34, and the core-exiting structure 20 is provided with a rotation direction limiting mating part 24 that matches the rotation direction limiting part 34.

[0042] When the core-ejecting structure 20 rotates relative to the outer shell 10, the rotation limiting part 32 and the rotation limiting fitting part 124 cooperate to make the core-ejecting structure 20 rotate relative to the rotation limiting part 32. The rotation direction limiting part 34 and the rotation direction limiting fitting part 24 make the core-ejecting structure 20 rotate only in a clockwise or counterclockwise direction.

[0043] Combination Figure 5 Specifically, in this embodiment, both the rotation direction limiting part 34 and the rotation direction limiting mating part 24 are inclined teeth.

[0044] The two inclined teeth cooperate with each other, so that when the core-ejecting structure 20 rotates relative to the rotation limit part 32, the core-ejecting structure 20 can only rotate in a clockwise or counterclockwise direction.

[0045] In other embodiments, the rotation direction limiting part 34 and the rotation direction limiting mating part 24 can also be other structures, as long as they can achieve the above functions.

[0046] Combination Figure 5 Specifically, in this embodiment, the rotation direction limiting fitting part 24 is provided on the rotation fitting part 22.

[0047] In other embodiments, the rotation direction limiting fitting part 24 may also be provided on other components of the core-exiting structure 20.

[0048] Referring to the accompanying drawings, specifically in this embodiment, the rotation direction limiting member 30 is a sleeve fitted onto the core-exiting structure 20, and the rotation direction limiting part 34 is an annular structure disposed at the end of the rotation direction limiting member 30.

[0049] Referring to the accompanying drawings, specifically in this embodiment, the rotation direction limiting fitting part 24 is also a ring structure.

[0050] Referring to the accompanying drawings, specifically in this embodiment, the rotation limiting part 32 and the rotation limiting mating part 124 are at least one of a groove and a protrusion, respectively.

[0051] In other embodiments, the rotation limiting part 32 and the rotation limiting mating part 124 can also be other structures, as long as they can achieve the corresponding functions.
