[0009] Preferably, a first limiting ring and a second limiting ring are fixedly mounted on the outer surface of the pen body, and the second limiting ring abuts against the side surface of the sliding telescopic sleeve.

[0010] Preferably, a second cavity is provided on the inner surface of the connecting seat, and two mounting grooves are provided on the inner wall of the second cavity.

[0011] Preferably, the inner surface of the connecting seat is provided with a tip of the reading pen, and two sliding grooves are provided on both sides of the tip of the reading pen.

[0012] Preferably, the inner surface of the slide is fixedly connected to an elastic component, and the elastic component includes: a second return spring, one end of the second return spring is connected to the inner wall of the slide, and the end of the second return spring away from the inner wall of the slide is fixedly connected to a sliding block, and the sliding block is slidably connected to the slide.

[0013] Preferably, a volume button and a display screen are provided on the outer surface of the pen body.

[0014] Preferably, the outer surface of the sliding telescopic sleeve is provided with anti-slip convex strips, and the inner wall of the first cavity abuts against the first limiting ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model proposes a head-changing structure for a point-reading pen;

[0017] By setting up a quick replacement component, when replacing the pen tip of the reading pen, the inner wall of the sliding telescopic sleeve is pushed to contact the first limit ring, so that the first return spring arranged on the outer surface of the pen body is compressed in the first cavity. In the process of pushing the sliding telescopic sleeve, the inner wall of the sliding telescopic sleeve is separated from the card bead, and then the card bead retracts under the action of pressure and separates from the slot on the connecting seat, so that the pen tip of the reading pen can be replaced.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 4 , the utility model provides a technical solution: a head-changing structure for a reading pen;

[0025] Example 1:

[0026] In order to quickly replace the worn tip 13 of the reading pen, a sliding telescopic sleeve 2 is provided on the outer surface of the pen body 1, and a first cavity 3 is provided on the inner surface of the sliding telescopic sleeve 2. A quick-changing component is provided on the inner surface of the first cavity 3. The quick-changing component includes: a first return spring 5, which is sleeved on the outer surface of the pen body 1 and contacts the inner wall of the first cavity 3. A card bead 9 is provided on the outer surface of the pen body 1, and a connecting seat 7 is provided on the inner wall of the pen body 1. A card groove 8 is provided on the outer surface of the connecting seat 7, and the card groove 8 is engaged with the card bead 9. A first limiting ring 4 and a second limiting ring 6 are fixedly installed on the outer surface of the pen body 1, and the second limiting ring 6 abuts against the side surface of the sliding telescopic sleeve 2. The outer surface of the sliding telescopic sleeve 2 is provided with anti-slip ridges 12, and the inner wall of the first cavity 3 is in contact with the first limiting ring 4. By pushing the inner wall of the sliding telescopic sleeve 2 to contact the first limiting ring 4, the first return spring 5 arranged on the outer surface of the pen body 1 is compressed in the first cavity 3. In the process of pushing the sliding telescopic sleeve 2, the inner wall of the sliding telescopic sleeve 2 is separated from the card bead 9, and then the card bead 9 retracts under the action of pressure and separates from the card slot 8 on the connecting seat 7, so that the pen tip 13 of the reading pen can be replaced. When the pen tip is worn or damaged, only the pen tip part needs to be replaced, instead of the entire reading pen, which reduces the cost of use and facilitates the quick disassembly and assembly of the pen tip 13 of the reading pen, thereby enhancing operational flexibility.

[0027] Example 2:

[0028] On the basis of the first embodiment, in order to fix the tip 13 of the reading pen to the connecting seat 7, a second cavity 10 is provided on the inner surface of the connecting seat 7, and two mounting grooves 11 are provided on the inner wall of the second cavity 10. The inner surface of the connecting seat 7 is sleeved with the tip 13 of the reading pen, and two slide grooves 14 are provided on both sides of the tip 13 of the reading pen. The inner surface of the slide groove 14 is fixedly connected to an elastic component, which includes: a second return spring 15, one end of the second return spring 15 is connected to the inner wall of the slide groove 14, and the end of the second return spring 15 away from the inner wall of the slide groove 14 is fixedly connected There is a sliding block 16, which is slidably connected to the sliding groove 14. By inserting the pen tip 13 into the connecting seat 7, the sliding block 16 is slidably connected through the sliding grooves 14 on both sides of the pen tip 13. During the insertion process, the outer surface of the sliding block 16 contacts the inner wall of the connecting seat 7, and the sliding block 16 is retracted into the sliding groove 14 through the rebound energy of the second return spring 15. When the sliding block 16 slides into the installation grooves 11 on both sides of the pen tip 13, a click sound is heard, indicating that the sliding block 16 is engaged with the installation groove 11, and the installation process of the pen tip 13 is completed.

[0029] Working principle: When using this device, first, in order to quickly replace the worn point reading pen tip 13, the inner wall of the sliding telescopic sleeve 2 is pushed to contact the first limiting ring 4, so that the first return spring 5 set on the outer surface of the pen body 1 is compressed in the first cavity 3. In the process of pushing the sliding telescopic sleeve 2, the inner wall of the sliding telescopic sleeve 2 is separated from the card bead 9, and then the card bead 9 retracts under the action of pressure and disengages from the card slot 8 on the connecting seat 7, thereby replacing the point reading pen tip 13. When the pen tip is worn or damaged, only the pen tip part needs to be replaced, rather than the entire point reading pen, which reduces the cost of use and is convenient for point reading. The reading pen tip 13 can be quickly disassembled and assembled to enhance operational flexibility. Secondly, in order to fix the reading pen tip 13 to the connecting seat 7, the reading pen tip 13 is inserted into the connecting seat 7, and a sliding block 16 is slidably connected through the slide grooves 14 on both sides of the reading pen tip 13. During the insertion process, the outer surface of the sliding block 16 contacts the inner wall of the connecting seat 7, and the sliding block 16 is retracted into the slide groove 14 through the rebound performance of the second return spring 15. When the sliding block 16 slides into the installation grooves 11 on both sides of the reading pen tip 13, a click sound is heard, indicating that the sliding block 16 is engaged with the installation groove 11, and the installation process of the reading pen tip 13 is completed.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
