All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1 to 3, this embodiment proposes a finger-attached pen cap, including:

the bottom sleeve 1 is used for being sleeved on a pen and provided with a limiting part 10;

the outer sleeve 2 is arranged on the bottom sleeve 1, and the outer sleeve 2 is close to or far away from the limiting part 10 after rotating;

the expansion sleeve 3 is slidably arranged on the bottom sleeve 1, the expansion sleeve 3 is connected between the limiting part 10 and the outer sleeve 2, and the outer sleeve 2 is rotated towards the direction close to or far away from the limiting part 10, so that the expansion sleeve 3 is extruded and expanded or stretched and contracted.

In this embodiment, in order to solve the problem that in the prior art, people use pens with unsuitable thickness, and after long-time use, the problem that hand fatigue can be caused, the design of this scheme has a pen cap that can adjust the thickness of holding the pen department, specifically include, cover the end cover 1 of establishing on the pen-holder, there is overcoat 2 through threaded connection on the end cover 1, still have one end and overcoat 2 butt simultaneously, the other end and the expansion sleeve 3 of the spacing portion 10 butt of end cover 1, specific adjustment method is through rotating overcoat 2, make end cover 1 and overcoat 2 move in opposite directions, extrude the expansion sleeve 3 in the centre, make expansion sleeve 3 have the bulge to expand, and then reach the effect of adjusting the thickness of holding the pen department, through this kind can adjust thickness form, make people find the most suitable thickness when writing, the practicality is greatly improved.

Further, the limiting portion 10 is a protruding block protruding outwards along the circumferential direction of the bottom sleeve 1, one end of the expansion sleeve 3 is abutted against the limiting portion 10, and the other end is abutted against the outer sleeve 2.

Further, the bottom sleeve 1 is provided with a threaded section 8 and a mounting section 9, the limiting part 10 is positioned on the mounting section 9, the expansion sleeve 3 is slidably arranged on the mounting section 9, and the outer sleeve 2 is in threaded arrangement on the threaded section 8.

Further, the thread section 8 is provided with a limiting protrusion 11, and the outer sleeve 2 is far away from or abuts against the limiting protrusion 11 after rotating.

In this embodiment, the end of the threaded section 8 far away from the limiting part 10 is provided with the limiting protrusion 11, when the thickness of the pen cap is adjusted, the pen cap is the thinnest state when the pen cap is rotated to the position where the limiting protrusion 11 is abutted against the outer sleeve 2, and in this way, the specific thickness state can be more conveniently known.

Further, the expansion sleeve 3 has an expansion opening 12, and after the outer sleeve 2 is rotated, the expansion sleeve 3 expands or contracts along the expansion opening 12.

In this embodiment, there is expansion port 12 in the middle of the expansion shell 3 of this scheme, and expansion shell 3 can be along expansion port 12's direction circumference expansion when the expansion shell 3 is pressurized, can not appear because of the too big condition that leads to expansion shell 3 to damage of pressure.

Further, the expansion shell 3 has an annular protrusion 13, the annular protrusion 13 abutting the outer jacket 2.

In this embodiment, in order to ensure the clamping state of the expansion sleeve 3 when the thickness is adjusted by rotation, the annular protrusion is arranged at one end of the expansion sleeve 3, which is abutted against the outer sleeve 2, and opposite to the limiting part 10 of the bottom sleeve 1, the protrusions for increasing the abutting area are arranged at both ends, so that the expansion sleeve 3 is ensured to be in a contact state when the thickness is adjusted, and the situation of falling out can not occur.

Further, the method further comprises the following steps:

the holding sleeve 4 is sleeved outside the expansion sleeve 3, and the holding sleeve 4 expands or contracts along with the expansion sleeve 3.

In this embodiment, in order to ensure the comfort of the finger when holding the pen for a long time, the holding sleeve 4 is sleeved on the expansion sleeve 3 in this scheme, the holding sleeve 4 is made of elastic material, such as rubber, flexible plastic, and other elastic deformable materials, and the holding sleeve 4 can expand or contract along with the expansion sleeve 3 in such a deformable manner.

Further, the grip cover 4 has at least one finger grip point portion 5.

In this embodiment, in order to further increase the comfort level when holding the pen, the finger holding point part 5 is provided in the circumferential direction of the hand grip sleeve 4, and when holding the pen, the finger is held at the finger holding point part 5, so as to increase the positioning guide of the finger, facilitate quick making of the correct holding gesture, such as setting the finger holding point part 5 for the index finger, the middle finger and the thumb, and in other embodiments, the number of the finger holding point parts 5 can be increased or decreased according to specific situations.

Further, at least one finger stall 6 is further included, the finger stall 6 is disposed on the hand-holding stall 4, and the finger stall 6 has a finger holding space 7.

In this embodiment, writing is performed by the wrong pen-holding posture, which is more laborious during writing, and the written fonts tend to be unsightly, so as to solve the problem, correct the pen-holding posture of people, when people hold a pen, the index finger stretches into the finger-holding space 7 of the fingerstall 6, the finger belly finger is held on the finger-holding point part 5, and at this time, the correct pen-holding posture is the correct pen-holding posture, and after the user is familiar with the pen-holding posture, the pen-holding posture of people can be corrected while the user's using habit can be adapted, so that the pen-holding posture of people can be corrected, and the pen-holding posture correction device has higher practical value.

Further, the outer sleeve 2 has a visible opening 14.

In this embodiment, the thickness of the outer sleeve 2 is adjusted, the number of rotation turns is too large, the situation that the outer sleeve 2 is separated from the threaded section 8 is unavoidable, and in order to avoid the occurrence of this situation, the visual opening 14 is provided on the outer sleeve 2, the opening position of the visual opening corresponds to the position of the threaded section 8, and when the outer sleeve rotates to the bottom end of the threaded section 8, the rotation is stopped, so that the separation situation is avoided.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
