[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-Figure 9As shown, a side-pressing ballpoint pen comprises a refill 1, a return spring 2, an upper shell 3 and a lower shell 4. A pen clip 17 is also provided on the upper shell 3. A hollow portion 5 is provided on the side of the upper shell 3. A first guide 6 is provided on the inner wall of the hollow portion 5. A press 7 is provided on the upper part of the refill 1. A clamping portion 8 for fixing the press 7 is provided on the first guide 6. The clamping portion 8 is used to fix the downward-moving press 7 at the lower end of the first guide 6 to achieve the fixation of the refill. A second guide 9 is provided on the press 7. The first guide 6 and the second guide 9 form a guide assembly. The first guide 6 and the second guide 9 cooperate with each other to achieve the back-and-forth sliding between the press 7 and the upper shell 3. When the refill 1 is retracted, the press 7 is fixed in the hollow portion 5 by the return spring 2. When the refill 1 is taken out, the press 7 is pressed in an oblique downward direction, and the press 7 moves along the guide assembly and is finally fixed in the clamping portion 8.

[0031] like Figure 3-Figure 9 As shown, the first guide member 6 is a vertically arranged guide bar 6, and the second guide member 9 is a vertically arranged guide groove 9. The guide bar 6 is inserted into the wire groove 9 and moves up and down under the action of external force. There are two guide bars 6, which are respectively arranged on both sides of the inner wall of the hollow part 5; there are two guide grooves 9, which are respectively arranged on both sides of the pressing member 7. The two guide bars 6 correspond to the two guide grooves 9 respectively, and the wire action of the wire groove 9 and the wire bar 6 is more stable and smoother when sliding. The lower end of the guide bar 6 is provided with an inclined arc surface 8, which is the aforementioned clamping part 8. The upper end of the pressing member 7 is semicircular. After the pressing member 7 moves out of the first guide member 6, it deviates to one side under the action of external force and enters the lower part of the inclined arc surface 8. The upper end of the pressing member 7 is clamped by the inclined arc surface 8 and fixed under the action of the reset spring 2. The upper end surface of the pressing member 7 is provided with an inclined abutting surface 10, the height of which gradually decreases from the middle to both sides, and the abutting surface 10 is used to prevent the pressing member 7 from scratching out of the locking portion 8. After the upper end of the pressing member 7 is fixed by the locking portion 8, in order to prevent it from sliding out of the locking portion, the abutting surface is arranged to be inclined, and when it is necessary to move out of the locking portion 8, the pressing member 7 needs to be pressed at another position.

[0032] 1. If Fig. 9As shown, a limit block 11 is provided on the inner wall of the upper shell 3, and a concave limit notch 12 is provided on the outer side of the second guide member 9 of the pressing piece 7. When the pressing piece 7 is inserted into the upper shell 3, the limit notch 12 is aligned with the limit block 11. The pressing piece 7 can only be inserted into the upper shell 7 from a specific angle. The limit block is located on the delay line of the first guide member, that is, when the pressing piece 7 is inserted into the upper shell 7, the first guide member 6 must be aligned with the second guide member 9, eliminating the step of aligning the first guide member 6 and the second guide member 9. A raised pressing portion 13 is provided on the side wall of the pressing piece 7. The pressing portion 13 enters the hollow portion 5 and is exposed from the hollow portion 5. The pressing portion 13 can be set to one or two. The two pressing portions 13 are respectively arranged on both sides of the pressing piece 7. At this time, the pressing piece 7 can be pressed in two directions, which is convenient for the use of the ballpoint pen. As shown Fig.10 , Fig.11 As shown, the lower end of the pressing piece 7 is a refill fixing assembly, which includes a base 18, a fixing column 14 and a fixing wall 15. The fixing column 14 is arranged at the top of the base 18, and the fixing wall 15 surrounds the outside of the fixing column 14. The side wall 16 of the pen tube at the top of the refill is accommodated between the fixing column 14 and the fixing wall 15. The base 18 is in the shape of a rectangular parallelepiped, and the fixing column 14 is in the shape of a square column and is arranged in the middle of the base 18. Thus, both common butterfly refills and Parker refills can be adapted. The butterfly refill is mainly fixed by the raised part at the root of the butterfly refill and the lower shell, and the upper position fixation requirement of the butterfly refill is relatively low; the Parker refill adopts an integral fixing method, and the fixing requirement for the upper part of the Parker refill is relatively high. The fixing column is inserted into the refill cavity of the butterfly refill to prevent the butterfly refill from shaking, and the butterfly refill can be further fixed. The fixing column supports the upper end of the Parker refill, and the fixing wall surrounds the upper end of the fixed refill to achieve the purpose of firmly fixing the Parker refill. The pressing member 7 is provided with a hollow hole 16, which is arranged below the second guide member. The hollow hole is used to reduce the volume and variety of the pressing member 7 and reduce the production cost of the pressing member 7.

[0033] The above is a detailed introduction to a side-press ballpoint pen provided by the present invention. The principle and implementation method of the present invention are described in detail using specific examples. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
