In the embodiment of the invention, the following steps are included: as shown in fig. 1, the longitudinal direction of the front case 1 is defined as the front-rear direction; as shown in fig. 6, the up-down direction of the paper surface is defined as the up-down direction, and the left-right direction of the paper surface is defined as the left-right direction.

As shown in fig. 1 to 10, the present invention provides a pen, comprising a front housing 1, a main skeleton 2 penetrating the front housing 1, and a rear housing 3, wherein a skeleton stopper 21 is provided at the front end of the main skeleton 2, and the skeleton stopper 21 abuts against the front end of the front housing 1; the rear end of the main framework 2 is fixedly connected with the rear shell 3, the rear shell 3 is provided with a rear shell stop part 31, and the rear shell stop part 31 abuts against the rear end of the front shell 1. The present invention realizes the assembly of the front case 1, the main frame 2, and the rear case 3 by the abutting action between the frame stopper 21 and the front end of the front case 1, the abutting action between the rear end of the front case 1 and the rear case stopper 31, and the connecting action between the main frame 2 and the rear case 3. The pen is simple in assembly form, convenient to implement and convenient to assemble; and no other connecting structures are required to be designed between the main framework 2 and the front shell 1 and between the front shell 1 and the rear shell 3, so that the integral structure of the pen is simplified, the pen is convenient to process and manufacture, and the processing cost of the pen is reduced.

Meanwhile, as shown in fig. 4 and 5, the present invention also provides an assembling method for assembling the pen, comprising the following steps in order:

s1, inserting the main framework 2 into the front shell 1 backwards until a framework stop part 21 at the front end of the main framework 2 abuts against the front end of the front shell 1;

s2, fixing the rear shell 3 and the rear end of the main framework 2, and enabling the rear shell stop part 31 on the rear shell 3 to abut against the rear end of the front shell 1.

The assembling method of the invention realizes the assembling of the pen by utilizing the abutting action between the framework stop part 21 and the front end of the front shell 1, the abutting action between the rear end of the front shell 1 and the rear shell stop part 31 and the connecting action between the main framework 2 and the rear shell 3; the assembling method is simple and convenient to implement, and the assembling cost of the pen is reduced.

In this embodiment, the cross-sectional dimension of the main frame 2 is smaller than the cross-sectional dimension of the inner wall of the front housing 1, that is, a gap is formed between the main frame 2 and the inner wall of the front housing 1, so as to ensure that the main frame 2 can be smoothly inserted into the front housing 1 in the step S1.

The invention is based on the above-mentioned assembled structure, so that the structure of the front housing 1 in the invention is simpler. For this reason, in the present embodiment, the front housing 1 is made of an aluminum alloy, and the front housing 1 can be obtained by extrusion molding of the aluminum alloy material, so as to reduce the processing cost of the front housing 1 and ensure that the strength of the front housing 1 is high. Meanwhile, in this embodiment, the rear housing 3 is made of plastic.

As shown in fig. 1 to 5 and 7, the front housing 1 has a rear end provided at a lower portion thereof with a rear housing extension 11 extending rearward, and the rear housing 3 has a rear housing extension 32 extending forward at an upper portion thereof, the rear housing extension 32 being located above the front housing extension 11. The structural design ensures that the pen has better aesthetic property, and increases the contact area between the front shell extension 11 and the rear shell extension 32, so that the front shell extension 11 and the rear shell extension 32 have better matching relationship.

As shown in fig. 1 to 5, 7 and 8, the rear case stopper 31 in the present embodiment includes a rear case upper stopper 311 abutting against the upper portion of the rear end of the front case 1 and a rear case lower stopper 312 abutting against the rear end of the front case extension 11; and the rear case upper stopper 311 is located at the front end of the rear case extension 32. The invention utilizes the abutting action of the rear shell upper stop part 311 and the rear shell lower stop part 312 and the front shell 1 to effectively prevent the front shell 1 from moving backwards relative to the rear shell 3; while also preventing the rear housing 3 from moving forward relative to the front housing 1.

As shown in fig. 1 to 5, 7 and 8, the rear case upper stopper 311, the rear case lower stopper 312 and the frame stopper 21 are all in a convex structure in the present embodiment.

As shown in fig. 2, 3 and 5, the rear end of the main frame 2 is fixed to the rear case 3 by a screw 5. The connecting structure is not only convenient for assembling the pen, but also convenient for disassembling the pen. The connection tightness of the main framework 2 and the rear shell 3 is conveniently adjusted by the bolts 5, so that the main framework 2, the front shell 1 and the rear shell 3 are tightly and reliably matched; and ensures that the front case 1 is clamped between the frame stopper 21 of the main frame 2 and the rear case stopper 31 of the rear case 3. At the same time, the degrees of freedom of the main frame 2, the front case 1, and the rear case 3 are also limited.

Meanwhile, as shown in fig. 5, the step S2 of the present embodiment includes the following steps in order:

s21, embedding the front end of the guide part 321 on the rear shell 3 in the front shell extension part 11 and pushing the rear shell 3 forwards, wherein the rear shell 3 is ensured to slide forwards smoothly according to a set path by utilizing the abutting action of the guide part 321 and the inner wall of the front shell extension part 11 in the process; until the rear shell upper stop part 311 abuts against the upper part of the rear end of the front shell 1, the rear shell lower stop part 312 abuts against the rear end of the front shell extension part 11, and at the moment, the two limit ribs 12 are respectively embedded in the two anti-rotation clamping grooves 34, the rear shell upper limit part 331 is embedded in the upper part of the rear end of the front shell 1, and the rear shell lower limit part 332 is embedded in the rear end of the front shell extension part 11;

s22, the screw 5 penetrates through a screw hole 35 at the rear end of the rear shell 3 and is connected with a screw hole 23 at the rear end of the main framework 2, so that the rear end of the main framework 2 is fixedly connected with the rear shell 3, and the pen is assembled.

After the pen is assembled, the limiting structure and the guiding structure of the pen are positioned in the front shell 1, namely the mounting structure is not exposed on the appearance surface; the invention not only ensures firm and reliable connection strength and precision; meanwhile, the pen has no influence on the product and no flaws, and has a better appearance surface. In addition, the assembly structure is adopted, so that the pen is convenient to assemble, disassemble and maintain in the later period.

In summary, the present invention effectively overcomes the disadvantages of the prior art and has high industrial utility value.
