[0022] Now, with reference to the accompanying drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0023] Referring to Figure 1 - Figure 5 As shown, the present utility model provides a technical solution: a telescopic anti-loss recording pen, including a housing 1, characterized in that: a recording pen body 2 is slidably connected inside the housing 1, a lock block 4 is fixed at the bottom of the recording pen body 2, a receiving groove 5 is opened at the bottom inside the housing 1, a slider 6 is slidably connected inside the receiving groove 5, elastic pieces 7 are fixed on both sides of the top of the slider 6, a thrust spring 8 is fixed at the bottom of the receiving groove 5, the top of the thrust spring 8 is fixedly connected to the bottom of the slider 6, a rotating rod 9 is rotatably connected inside the slider 6, a guiding block 10 is fixedly connected to the top of the rotating rod 9, a first guiding plate 11 is fixed inside the receiving groove 5, a second guiding plate 12 is fixed inside the receiving groove 5, a placing groove 13 is opened inside the slider 6, one end of a return spring 14 is fixed on one side of the placing groove 13, and the other end of the return spring 14 is fixedly connected to one end of the rotating rod 9. When the user presses the recording pen body 2 to move the lock block 4 fixed at the bottom downward, the slider 6 will be pushed downward, the elastic pieces 7 on both sides of the receiving groove 5 will be squeezed, causing the elastic pieces 7 to move toward the middle to fasten the lock block 4. At the same time, when the receiving groove 5 moves downward, it will drive the guiding block 10 to move downward. Being squeezed by the first guiding plate 11, it will rotate. When it moves to the middle position between the first guiding plate 11 and the second guiding plate 12, the extrusion is released. Under the action of the return spring 14, the rotating rod 9 rotates, driving the guiding block 10 to enter the inside of the first guiding plate 11 and the second guiding plate 12 to limit the slider 6, and the recording pen body 2 is fixed inside the housing 1. If the user needs to use it, just give the recording pen body 2 a downward force, which will push the guiding block 10 to continue moving downward along the other side of the first guiding plate 11 and the second guiding plate 12 under the restoring force of the return spring 14. The thrust spring 8 pushes the slider 6 upward, and the lock block 4 and the elastic piece 7 will be released from the fastening, so that the recording pen body 2 can be pulled out for use.

[0024] Referring to Figure 3 As shown, in this implementation: the length of the lock block 4 is greater than the length of the elastic piece 7, so that the lock block 4 can push the slider 6 to a certain distance downward to enable the elastic piece 7 to fasten it. When moving upward, if the length of the lock block 4 is not greater than that of the elastic piece 7, it will get stuck here and cannot play the upward role.

[0025] Referring to Figure 4 As shown, in this implementation: the distance between the bottom of the first guiding plate 11 and the top of the second guiding plate 12 is adapted to the diameter of the guiding block 10. The distance between the first guiding plate 11 and the second guiding plate 12 is set to be adapted to the size of the guiding block 10, so that the guiding block 10 cannot slide in other directions in the middle of the first guiding plate 11 and the second guiding plate 12.

[0026] Referring to Figure 6 And Figure 7As shown, in this embodiment: a through hole 22 is formed on one side of the housing 1, and a plug rod 15 is slidably connected inside the through hole 22. A slot 21 is formed on one side of the voice recorder body 2. When the user moves upward to the use position, in order to prevent the housing 1 from sliding down automatically, the plug rod 15 can be inserted into the slot 21 for limiting to prevent it from falling.

[0027] Referring to Figure 6 As shown, in this embodiment: limiting grooves 16 are formed at the top and bottom inside the through hole 22. Limit blocks 17 are fixed at the top and bottom of the plug rod 15. A tension spring 18 is fixed on one side of the limit block 17, and one end of the tension spring 18 is fixedly connected to one side inside the limiting groove 16. In order to enable the user not to press the plug rod 15 for a long time, the position of the voice recorder body 2 can be continuously kept unchanged by the tension between the tension spring 18 fixed to the housing 1 and the elastic piece 7.

[0028] Referring to Figure 1 As shown, in this embodiment: a limiting chute 3 is formed on one side of the voice recorder body 2, and a stop block 20 is fixed inside the housing 1. When the user pulls the voice recorder body 2 upward, in order to prevent the voice recorder body 2 from detaching from the inside of the housing 1 due to excessive pulling, the upward movement will stop by the limit of the stop block 20.

[0029] Working principle: When the user presses the voice recorder body 2 and the locking block 4 fixed at the bottom moves downward, it will push the slider 6 downward. The two sides of the storage groove 5 squeeze the elastic pieces 7, causing the elastic pieces 7 to move towards the middle and buckle the locking block 4. At the same time, when the storage groove 5 moves downward, it will drive the guiding block 10 to move downward. Under the extrusion of the first guiding plate 11, it will rotate. When it moves to the middle position between the first guiding plate 11 and the second guiding plate 12, the extrusion is released. Under the action of the return spring 14, the rotating rod 9 rotates, driving the guiding block 10 to enter the interior of the first guiding plate 11 and the second guiding plate 12 to limit the slider 6. The voice recorder body 2 is fixed inside the housing 1. If the user needs to use it, just applying a downward force to the voice recorder body 2 will push the guiding block 10 to continue moving downward along the other side of the first guiding plate 11 and the second guiding plate 12 under the return force of the return spring 14. The thrust spring 8 pushes the slider 6 upward, and the locking block 4 and the elastic piece 7 will be released from the buckling, so that the voice recorder body 2 can be pulled out for use. In order to make the locking block 4 push the slider 6 to a certain distance downward before the elastic piece 7 can buckle, and when moving upward, if the length of the locking block 4 is not greater than that of the elastic piece 7, it will get stuck here and cannot play the upward role. The distance between the first guiding plate 11 and the second guiding plate 12 is set to be adapted to the size of the guiding block 10, so that the guiding block 10 cannot slide in other directions in the middle of the first guiding plate 11 and the second guiding plate 12. When the user moves it upward to the use position, in order to prevent the housing 1 from sliding down automatically, the insertion rod 15 can be inserted into the slot 21 for limiting to prevent it from falling. In order to allow the user not to press the insertion rod 15 for a long time, the position of the voice recorder body 2 can be continuously maintained by the tension between the tension spring 18 fixed between the housing 1 and the elastic piece 7. When the user pulls the voice recorder body 2 upward, in order to prevent the voice recorder body 2 from detaching from the interior of the housing 1 due to excessive pulling, the upward movement will stop by the limit of the stop block 20.
