DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-Figure 7 The present embodiment is a pen with adjustable center of gravity, comprising a pen body 1, a counterweight 2 and an adjusting ring 3. The counterweight 2 is slidably arranged on the pen body 1 along the axis of the pen body 1, and the adjusting ring 3 is rotatably arranged on the pen body 1. A transmission mechanism 4 is arranged between the adjusting ring 3 and the counterweight 2. When the adjusting ring 3 is rotated, the counterweight 2 is driven to slide on the pen body 1 through the transmission mechanism 4.

[0025] When the utility model is used, the counterweight block 2 is driven to slide along the axis of the pen shaft 1 by rotating the adjustment ring 3, so as to adjust the upper and lower positions of the counterweight block 2 when the utility model is held vertically, thereby adjusting the center of gravity of the utility model. Therefore, the utility model can conveniently adjust the center of gravity of the pen through the adjustment ring 3, so that the user can adjust the center of gravity position of the pen according to personal preference or demand, thereby improving the writing experience and use efficiency.

[0026] See also Figure 1 , Figure 3 , Figure 5The transmission mechanism 4 includes a rotating rod 41 and a gear joint mechanism 42. The rotating rod 41 is rotatably arranged in the pen shaft 1. The adjusting ring 3 drives the rotating rod 41 to rotate through the gear joint mechanism 42. A threaded section 43 is arranged on the rotating rod 41. The threaded section 43 is connected to the counterweight block 2 through a threaded structure. The counterweight block 2 moves along the linear guide rail 11 on the pen shaft 1 and cannot rotate.

[0027] When the user rotates the adjustment ring 3, the adjustment ring 3 drives the rotating rod 41 to rotate in the pen barrel 1 through the gear joint mechanism 42. Since the rotating rod 41 and the counterweight 2 are connected by a threaded structure, and the counterweight 2 cannot rotate relative to the pen barrel 1 under the action of the linear guide 11, the rotating rod 41 can drive the counterweight 2 to move left and right in the pen barrel 1 when rotating clockwise or counterclockwise, so as to adjust the position of the counterweight 2, that is, to adjust the center of gravity of the utility model. The transmission mechanism 4 is arranged in the pen barrel 1, and has a relatively simple structure and is easy to assemble.

[0028] See also Figure 4 , Figure 7 The gear combination mechanism 42 includes four gears 44 arranged on the pen body 1 in a circular shape and at equal intervals. The gears 44 are rotatably arranged on the pen body 1. The inner side surface of the adjusting ring 3 is provided with gear teeth. The adjusting ring 3 is sleeved on the outer sides of the four gears 44. The rotating rod 41 is provided with a gear segment 45 with gear teeth. The gear segment 45 is located in the middle of the four gears 44. The inner side surface of the adjusting ring 3 and the gear segment 45 are both engaged with the gear 44.

[0029] When the adjusting ring 3 rotates, the meshing action of the gear teeth drives the four gears 44 to rotate in the same direction at the same time. The rotation of the gear 44 drives the rotating rod 41 to rotate through the meshing action of the gear teeth, so that the counterweight 2 is driven to move when the rotating rod 41 rotates. Through the gear joint mechanism 42, while ensuring that the pen barrel 1 in the position of the adjusting ring 3 remains connected, the adjusting ring 3 can be set on the outside of the pen barrel 1 to drive the rotation of the rotating rod 41 located in the pen barrel 1. The adjusting ring 3 is set on the outside of the pen barrel 1 to facilitate the user's operation. At the same time, the user's rotation of the adjusting ring 3 also has a certain decompression effect, thereby improving the functionality of the utility model.

[0030] See also Figure 3 , Figure 4 , Figure 6 The pen shaft 1 includes an upper pen shaft 12 and a lower pen shaft 13 which are plugged and fixed with each other. The gear 44 and the adjusting ring 3 are arranged on the upper pen shaft 12. The upper pen shaft 12 is provided with four mounting openings 14 for the gear 44 to be inserted and rotated. Two linear guide rails 11 are symmetrically arranged relative to the pen shaft 1 and penetrate through the lower pen shaft 13. The counterweight block 2 is arranged in the lower pen shaft 13, and the counterweight block 2 is provided with two protrusions 21 inserted into the linear guide rail 11.

[0031] By splitting the pen holder 1 into the upper pen holder 12 and the lower pen holder 13, and inserting the gear 44 into the installation opening 14 to achieve installation, it is convenient to subsequently sleeve the adjustment ring 3 on the gear 44 and insert the gear segment 45 of the rotating rod 41 between the four gears 44, thereby facilitating the assembly of the utility model. The two bosses 21 on the counterweight 2 cooperate with the linear guide 11 to limit the counterweight 2 from linear movement while preventing it from rotating. At the same time, the through-type linear guide 11 facilitates the user to judge the position of the counterweight 2 by observing the position of the boss 21, so that the user can quickly adjust the counterweight 2 to the desired position, thereby improving the convenience of the utility model when used.

[0032] See also Figure 3 A refill 5 is arranged in the pen barrel 1, and a spring 51 is sleeved on the refill 5 to drive the refill 5 to move into the pen barrel 1. A top component 6 is inserted at the right end of the upper pen barrel 12, and a pressing rod 61 is slidably arranged in the top component 6. A plug-in component 62 is slidably arranged in the upper pen barrel 12, and the plug-in component 62 is abutted against the upper pen barrel 12. The right end of the plug-in component 62 is inserted and fixed into the left end of the pressing rod 61. The plug-in component 62 drives the refill 5 to extend and retract into the pen barrel 1 through a telescopic locking mechanism.

[0033] The telescopic locking mechanism in the present invention adopts a conventional telescopic locking mechanism. When the present invention is not in use, the telescopic locking structure can be driven to work by pressing the pressing rod 61. The pressing rod 61 and the plug connector 62 as a whole can retract the refill 5 into the pen holder 1 under the action of the spring 51, thereby protecting the tip of the refill 5. The top member 6 is provided to facilitate the installation of the pressing rod 61 on the pen holder 1. At the same time, the pressing rod 61 is fixed on the plug connector 62 to prevent the pressing rod 61 from being pushed out of the pen holder 1 by the refill 5, thereby ensuring the normal function of the present invention.

[0034] See also Figure 3 , Figure 5 , Figure 7 A circular protrusion 46 is provided between the threaded section 43 and the gear section 45 of the rotating rod 41, and the protrusion 46 abuts against the gear 44. The left end of the rotating rod 41 abuts against the lower pen rod 13. The rotating rod 41 is a hollow structure with openings at both ends. The pen core 5 is inserted into the rotating rod 41, and the telescopic locking mechanism is provided in the rotating rod 41.

[0035] The rotating rod 41 is fixed in the pen shaft 1 by the protrusion 46 resting on the gear 44 and the left end resting on the lower pen shaft 13, so that the telescopic locking mechanism can be set in the rotating rod 41. When the user presses the pressing rod 61 to drive the telescopic locking mechanism to move, the rotating rod 41 in a fixed state will not affect the normal function of the telescopic locking mechanism.

[0036] See also Figure 1-Figure 3 The connector 62 is provided with two insertion holes 63 , and a pen clip 64 is provided on the connector 62 . The two insertion ends of the pen clip 64 are respectively inserted into two openings on different sides of the two insertion holes 63 .

[0037] In the present invention, the pen clip 64 is made of an elastic material (such as stainless steel). When the pen clip 64 is installed on the plug-in connector 62, the two plug-in ends of the pen clip 64 are separated and inserted into two openings on different sides of the two plug holes 63. The pen clip 64 is clamped and fixed on the plug-in connector 62 under the elastic action of the pen clip 64 itself, and the assembly is convenient.

[0038] See also Figure 1 The outer surface of the adjusting ring 3 is provided with anti-slip grooves to reduce the slippage between the fingers and the adjusting ring 3 when the user uses the fingers to clamp and rotate the adjusting ring 3, thereby improving the user experience of the utility model.
