detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 to 3, the new combined mechanical pencil described in the embodiment of the present invention adopts a modular design idea, and each independent module is a unit with complete functions, and the small holes of the pen head 5 parts of different unit modules The diameters are different, so as to install lead cores of different specifications (the diameters of lead cores of different specifications are different), and the unit modules can be combined end to end. The diameter of the pen body 2 of the latter unit module is the same as that of the front unit module. 4. The diameter of the tail hole is consistent, so the combination composed of different unit modules connected end to end can be compatible with various lead cores at the same time. If you need to switch to the rear unit module during use, just pull out the front unit module After going out, insert it into the tail hole of the unit module rotating head 4 at the end of the assembly.

Each unit module is composed of a pen body 2, a rotor 3, a rotating head 4 and a lead core 1. The inner hole of the pen body 2 and the outer cylindrical surface of the rotor 3 are both processed with threads of the same parameters, and the threads of the two match, so when the rotor 3 rotates around the axis inside the pen body 2, the rotation along the axis of the pen body 2 can be realized. Move back and forth, and force the lead 1 to move back and forth along the axis of the pen body 2 at the same time, so as to realize the extension and retraction of the lead 1. The swivel head 4 can be inserted into the rear portion of the pen body 2 inner hole, and the rear portion of the pen body 2 inner hole has no thread, so the swivel head 4 can perform pure rotary motion at the rear portion of the pen body 2 inner hole, and the front end structure of the swivel head 4 is Two parallel splints, the length of which extends to the frontmost position of the inner hole thread of the pen body 2, can always clamp both sides of the rotor 3 so that the rotor 3 rotates around the axis of the pen body 2 together with the rotating head 4, and at the same time realizes the rotor 3 and the lead core 1 move back and forth along the axis of the pen body 2 to complete the functions of stretching out the lead core 1 during use and retracting when not in use.

Use (extend) or carry (retract the lead). When using the new combined mechanical pencil, turn (clockwise, right-hand thread) the rotating head 4, and the two parallel splints at the front end of the rotating head 4 clamp the rotor 3 and rotate together. While the axis of the pen is rotating, it moves along the axis direction, and then the lead core 1 is pushed out from the small hole of the nib 5 . When not in use, reversely rotate (counterclockwise) the rotating head 4 to make the lead 1 withdraw into the inside of the pen body 2 to protect the lead 1 .

Switch cell modules. When it is necessary to use the following unit module for drawing, pull out the unit module before the target unit module to be used along the axis direction of the combination, and insert the front end of the drawn unit module pen body 2 into the rotating head of the unit module at the end of the combination 4 in the rear end hole, so far, the target unit module has been switched to the front end of the assembly.

Replace lead. After using for a period of time, the lead core 1 is about to be consumed, the length is greatly shortened, and the lead core can be replaced. Turn the rotating head 4 clockwise until the rotor 3 is pushed into the pen body 2 and close to the front end of the nib 5, pull out the old lead 1 from the small hole of the nib 5, and put the new lead 1 out of the nib 5 hole again. Put it in, turn the rotating head 4 counterclockwise until the lead 1 is completely received in the pen body 2, and the replacement of the lead is completed.

To sum up, the utility model discloses a novel combined mechanical pencil, the length of a unit module is 65mm (excluding the exposed part of the lead core 1), and the maximum diameter is 10mm. The total length of the combination (3 in 1) composed of 3 unit modules is only 155mm. The combination (4 in 1) composed of 4 unit modules has a total length of only 200mm, which is similar to the length of an ordinary pencil, and at this time (4 in 1) the new combined mechanical pencil can be compatible with 4 different types of lead Core, very convenient to carry and use.

Simultaneously, this novel combined mechanical pencil is not a one-time item, and it can be very convenient to replace the new lead core after the lead core 1 is used up and continue to use. In the entire life cycle of the new combined mechanical pencil, the consumables are always lead cores and will not consume any wood or paper, which is beneficial to the protection of scarce forest resources and conforms to the contemporary social concept of low-carbon and environmental protection.
