DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0025] See also Figure 1-Figure 3 The present embodiment is a pen with a double-layer penholder, comprising a penholder 1 and a sleeve 2. The penholder 1 is provided with a refill 3. The sleeve 2 is a tubular structure with two ends open. The sleeve 2 is sleeved and detachably mounted on the upper part of the penholder 1. There is a gap 4 between the sleeve 2 and the penholder 1 for placing display paper, which ensures the accommodation effect of the display paper between the sleeve 2 and the penholder 1. The edge of the top end of the sleeve 2 is bent inward to form an extension 21, and the extension 21 covers the edge of the top end of the penholder 1, so that the display paper will not fall out of the top end of the sleeve 2.

[0026] In this embodiment, the display paper may be printed with text or patterns. The sleeve rod 2 may be made of a transparent material so that the content of the display paper can be displayed. The sleeve rod 2 may also be partially hollowed out so that the part of the display paper that needs to be displayed can be displayed through the hollowed-out part.

[0027] See also Figure 1A raised portion 5 is provided on the outer side surface of the top end of the sleeve rod 2, which can limit the rolling of the pen, thereby reducing the risk of the pen falling from a high place and being damaged due to rolling when placed. A through hole 51 is opened on the raised portion 5, which is convenient for hanging the pen and can also be used to hang pendants.

[0028] See also Figure 1-Figure 3 The pen body 1 comprises an upper rod body 11 and a lower rod body 12, both of which are tubular structures with openings at both ends, a sleeve rod 12 is sleeved outside the upper rod body 11 and the bottom end of the sleeve rod 12 is detachably mounted on the top end of the lower rod body 11, the bottom end of the upper rod body 11 is detachably mounted on the top end of the lower rod body 12, a tip sleeve 13 is inserted and detachably mounted on the bottom end of the lower rod body 12, and a rubber leather cover 6 is sleeved on the lower rod body 12. Through the assembled structure of the pen body 1, the difficulty of installing the internal parts of the pen body 1 is reduced, and the components of the pen body 1 can be manufactured separately, which can reduce the manufacturing difficulty and manufacturing loss at the same time.

[0029] In this embodiment, the tip sleeve 13, the lower rod body 12, the upper rod body 11 and the sleeve rod 2 are connected in sequence by a threaded structure. The specific connection method between the lower rod body 12, the upper rod body 11 and the sleeve rod 2 is as follows: the top end of the lower rod body 12 is provided with an internal thread and an external thread, the bottom end of the upper rod body 11 is provided with an external thread, and the external thread at the bottom end of the upper rod body 11 is threadedly connected with the internal thread at the top end of the lower rod body 12; the bottom end of the sleeve rod 2 is provided with an internal thread, and the internal thread at the bottom end of the sleeve rod 2 is threadedly connected with the external thread at the top end of the lower rod body 12.

[0030] Of course, the specific connection method between the lower rod body 12, the upper rod body 11 and the sleeve rod 2 is only a preferred method. In addition, interference fit, snap fit and other methods can also be used to achieve a detachable connection between the three.

[0031] In this embodiment, the rubber cover 6 has two configuration modes, as follows:

[0032] (1) The diameter of the rubber sheath 6 gradually decreases from top to bottom and then gradually increases. The diameter of the top of the rubber sheath 6 is larger than the diameter of the bottom, which is beneficial to improving the user's grip on the pen. The upper part of the lower rod body 12 is provided with a plurality of annular pieces 14 arranged at equal intervals along its axial direction. The diameter of each annular piece 14 decreases from top to bottom. The rubber sheath 6 is sleeved on the annular piece 14 (such as Figure 2 , Figure 3 As shown in ), while ensuring the stability of the shape of the rubber sheath 6, it can also reduce the amount of materials required for manufacturing the rubber sheath 6 and the lower rod body 12, thereby reducing the manufacturing cost.

[0033] (2) The rubber sheath 6 is provided with two finger pressing parts 61 (such as Figure 7 ), which can improve the user's holding stability of the pen and also play a role in correcting the pen holding posture to a certain extent.

[0034] See also Figure 2 The diameters of the upper rod body 11 and the sleeve rod 2 increase from top to bottom, which ensures the comfort of holding and facilitates the user to use the press cap 8 to push out the display paper retained in the sleeve rod 2 when replacing the display paper on the pen, thereby improving the convenience of replacement. At the same time, since the display paper clip is arranged between the upper rod body 11 and the sleeve rod 2, the display paper can be displayed at an angle, thereby facilitating the display effect of the content on the display paper.

[0035] See also Figure 2 , Figure 3 A decorative ring 7 is sleeved on the bottom end of the sleeve rod 2 to embellish the appearance, thereby improving the visual effect of the pen appearance.

[0036] See also Figure 3 A press cap 8 is slidably provided on the pen barrel 1, and the refill 3 is slidably provided in the cavity of the pen barrel 1. The press cap 8 drives the refill 3 in the pen barrel 1 to extend or retract through a telescopic locking mechanism 9, which improves the convenience of using the pen and enables the pen barrel 1 to protect the refill 3, thereby reducing the use of the pen cap and reducing the risk of the refill 3 being exposed and damaged due to the loss of the pen cap.

[0037] See also Figure 2 , Figure 3 as well as Figure 6 The telescopic locking mechanism 9 includes a guide rail member 91 and a locking member 92. The guide rail member 91 is inserted and fixed on the top end of the pen barrel 1. A spring 93 is provided between the bottom end of the pen core 3 and the pen barrel 1. The two ends of the spring 93 are respectively against the pen core 3 and the pen barrel 1. The locking member 92 is located between the top end of the pen core 3 and the guide rail member 91. The locking member 92 is slidably arranged in the pen barrel 1 and can rotate. A plurality of slide grooves 94 arranged in a circular ring at equal angles around the axis thereof are provided on the guide rail member 91. A card slot 95 is provided between adjacent slide grooves 94, and the depth of the card slot 95 is less than the depth of the slide groove 94. A slide bar 96 corresponding to the slide groove 94 is provided on the locking member 92. A pressure rod member 97 for driving the slide bar 96 to sequentially and alternately enter the slide groove 94 and the card slot 95 is slidably connected to the guide rail member 91. The press cap 8 is sleeved and fixed on the top end of the pressure rod member 97.

[0038] In this embodiment, the telescopic locking mechanism 9 adopts the conventional setting structure of the telescopic locking mechanism 9 in the press pen. In the process of extending the pen core 3 from the pen body 1, the mechanism pushes the pressure rod 97 so that the pressure rod 97 pushes the locking member 92 away from the guide rail member 91, and after the locking member 92 and the guide rail member 91 are completely separated (that is, the slide bar 96 is separated from the slide groove 94), the locking member 92 is guided to rotate a certain angle through the inclined surface structure, and then after the pressure rod 97 stops pushing, the locking member 92 is pressed against the guide rail member 91 under the action of the spring 93 to restore the original state (that is, the slide bar 96 is located in the card slot 95). Since the depth of the slide groove 94 is greater than the depth of the card slot 95, the extension and retraction effect of the pen core 3 is achieved.

[0039] In this embodiment, the guide rail member 91 and the pen barrel 1 as well as the push cap 8 and the pressure rod member 97 are connected by interference fit.

[0040] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
