[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1:

[0040] like Figures 1 to 8 As shown, Embodiment 1 of this utility model provides a magnetic suction structure for storing the receiver 2 of a laser page turner. The magnetic suction structure designed in this utility model comprises two main parts: an insert block 1 and a storage section 5. The storage section 5 is an injection-molded shell with a rectangular storage cavity 6 inside, the width of which is fitted with a clearance between the insert block 1 and the receiver 2. The insert block 1 is a rectangular structure with a wedge-shaped guide surface at its front end, facilitating automatic position correction when inserted into the storage cavity 6, and is fixedly connected to the receiver 2 of the laser page turner at its front end. A transverse through hole is formed in the center of the insert block 1, and a magnetic sheet 3 is fixedly installed inside the through hole, dividing the through hole into symmetrical left and right limiting grooves 4. This design allows the user to insert the receiver 2 into the storage cavity 6 without needing to distinguish between the front and back sides.

[0041] The storage cavity 6 has a transverse sliding groove in its wall, and a sliding locking piece 7 is provided on the sliding groove. The end of the locking piece 7 matches the shape of the limiting groove 4. When the insert 1 is fully inserted into the storage cavity 6, the magnetic piece 3 and the locking piece 7 are in the same position. Under the magnetic attraction of the magnetic piece 3, one end of the locking piece 7 is embedded in the limiting groove 4, forming a mechanical limit, so that the insert 1 cannot fall out of the storage cavity 6.

[0042] This invention combines the magnetic attraction function with the mechanical limiting groove 4 to form a dual fixing mechanism of "magnetic attraction + mechanical locking". The magnetic attraction force achieves automatic locking, and the mechanical limiting prevents lateral displacement, thus solving the problem that traditional pure magnetic attraction structures are easily detached by external forces.

[0043] Example 2:

[0044] On the basis of solving the storage problem in the embodiment one, the utility model also designs the related structure of taking out the receiver 2 from the storage cavity 6. Figures 3 to 7 As shown in the utility model, the linear slide 8 is designed outside the storage part 5, the push button 9 is slidably installed in the slide 8, the inside of the push button 9 is fixed with the protruding ring 19, the diameter of the protruding ring 19 is greater than the width of the slide 8, and the push button 9 is prevented from coming out.

[0045] The push block 10 is slidably installed in the storage cavity 6, and one end of the push block 10 extends from the side wall of the storage cavity 6. The slidable push block 11 is also installed in the storage part 5, and the through slot 12 is formed in the lock piece 7 for the push block 11 to insert. The sliding direction of the push block 11 is perpendicular to the sliding direction of the lock piece 7. Meanwhile, the limiting sleeve 14 is fixed in the storage part 5, the rod body 13 is slidably installed in the limiting sleeve 14, the top of the rod body 13 is connected with the push button 9, and the bottom of the rod body 13 is fixed with the first driving strip 15 and the second driving strip 17.

[0046] As shown in the utility model, Figure 4 and Figure 8 the end, away from the rod body 13, of the first driving strip 15 and the second driving strip 17 is respectively provided with the inclined first driving part 16 and the inclined second driving part 18. Meanwhile, the first driving strip 15 is also designed with the first reset part 25. The first reset part 25 is also inclined.

[0047] When the push button 9 slides downward along the slide 8, the second driving part 18 on the second driving strip 17 first contacts the push block 11, the second driving part 18 pushes the push block 11 in the direction away from the storage cavity 6, thereby pulling the lock piece 7 out of the limiting slot 4, so that the plug 1 loses mechanical limiting. When the push button 9 continues to slide downward, the first driving part 16 on the first driving strip 15 collides with the part of the push block 10 extending out of the storage cavity 6, thereby driving the push block 10 to slide in the storage cavity 6, so that the receiver 2 is partially pushed out of the storage cavity 6, and the user can directly pull the push block 10 by hand, thereby completely taking out the receiver 2 and the push block 10 from the storage part 5.

[0048] In order to make the first driving strip 15 and the second driving strip 17 move more stably, the utility model also designs the guide rail 24 in the storage part 5, the guide rail 24 is slidably matched with the first driving strip 15 and the second driving strip 17, thereby providing guidance for them.

[0049] As shown in the utility model, Figure 6 in order to make the push block 10 be able to reset, the first spring 21 is sleeved on the rod body 13 between the limiting sleeve 14 and the push button 9, when the user no longer pushes the push button 9, the push button 9 can reset along the slide 8 under the action of the first spring 21, at this time, the first reset part 25 will rise and push the push block 10 to reset.

[0050] With the above settings, users can easily move the push button 9 along the slide 8 to release the locking piece 7 from the insertion block 1 and push the receiver 2 part out of the storage cavity 6 for easy removal of the receiver 2.

[0051] Example 3:

[0052] like Figure 6 As shown, based on Embodiment 2, to prevent accidental sliding of the push button 9, this invention also designs a slot 20 at the top of the slide 8 and a recessed groove 23 on the push button 9. The diameter of the slot 20 is larger than the width of the slide 8 but smaller than the diameter of the push button 9, so that the push button 9 cannot move along the slide 8 when it is stuck in the slot 20. A pin is fixed on the push button 9 and inserted into the rod 13. A second spring 22 is sleeved on the pin between the convex ring 19 and the rod 13. The diameter of the convex ring 19 is larger than the width of the slide 8 and also larger than the diameter of the slot 20. Only the position of the recessed groove 23 of the push button 9 matches the width of the slide 8.

[0053] With the above configuration, when the push button 9 slides to the slot 20 at the top of the slide rail 8, the push button 9 is locked in the slot 20 under the action of the second spring 22, and the recess 23 is misaligned with the slide rail 8, preventing the push button 9 from moving along the slide rail 8. Only when the user presses the push button 9, causing it to compress the second spring 22 and align the recess 23 with the slide rail 8, can the push button 9 be moved along the slide rail 8. This greatly reduces the risk of accidental sliding and avoids accidental contact that could release the limit on the insert block 1.

[0054] Example 4:

[0055] This invention proposes a laser page turner pen, which includes the magnetic structure described in the above embodiments, and can better preserve the receiver 2 and prevent the receiver 2 from being lost.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
