All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.
[0020] The utility model provides an anti-fall fountain pen, comprising a fountain pen body 1, a pen cap 2 is arranged on the circumferential surface of the fountain pen body 1, a first slide groove 3 is provided on the circumferential surface of the pen cap 2, a pressure block 4 is slidably connected in the first slide groove 3, a clamping block 5 is fixedly connected at the lower end of the pressure block 4, the clamping block 5 and the pen cap 2 are slidably connected, a clamping groove 6 is provided on the circumferential surface of the fountain pen body 1, the clamping block 5 is located in the clamping groove 6, a first spring 7 is fixedly connected between the pressure block 4 and the clamping groove 6, a connecting block 8 is fixedly connected on the circumferential surface of the pen cap 2, a clamping rod 9 is fixedly connected on the surface of the connecting block 8, and the lower end of the clamping rod 9 is in contact with the surface of the clamping block 4. When working, when the pen cap 2 needs to be closed on the fountain pen body 1, the clamping rod 9 is extracted forward at this time, and the first spring 7 pushes the pressure block 4 upward under the action of the first spring 7. When the pen cap 2 is removed, the first spring 7 can be used to pull the clamping rod 9 upwards, and the first spring 7 can be used to pull the clamping rod 9 upwards, and the clamping rod 9 can be used to loosen the clamping rod 9. When the pen cap 2 is completely pushed to the bottom, the clamping block 5 will coincide with the clamping slot 6, and then the clamping block 4 will be pressed downwards by the clamping rod 9, and the clamping block 4 will drive the clamping block 5 to move downwards, so that the clamping block 5 is inserted into the clamping slot 6, thereby achieving the effect of stably fixing the pen cap 2 on the pen body 1. When the pen falls, the pen cap 2 will not be separated from the pen body 1, thereby avoiding damage to the pen tip. At the same time, when the pen cap 2 needs to be removed, it is only necessary to extract the clamping rod 9 upwards. At this time, the first spring 7 will drive the pressing block 4 to move upwards, and the pressing block 4 will drive the clamping block 5 to separate from the clamping slot 6, and then the pen cap 2 can be removed.
[0021] Furthermore, a limiting groove 10 is opened in the first slide groove 3, and the circumferential surface of the block 5 is fixedly connected to the limiting rod 11, and the limiting rod 11 is slidably connected to the limiting groove 10. During operation, the moving position of the block 5 can be limited by the action of the limiting groove 10 and the limiting rod 11 to prevent the block 5 from escaping from the first slide groove 3.
[0022] Furthermore, a first correction line 12 is provided on the circumferential surface of the pen body 1, and a second correction line 13 is provided on the circumferential surface of the pen cap 2. The first correction line 12 is aligned with the second correction line 13. During operation, the position of the pen cap 2 can be corrected by the action of the first correction line 12 and the second correction line 13. When the pen cap 2 is pushed to the bottom on the pen body 1, it is only necessary to rotate the pen cap 2 or the pen body 1 to align the first correction line 12 with the second correction line 13, and then the card block 5 will be inserted into the card slot 6 to fix the pen cap 2.
[0023] Furthermore, a second slide groove 14 is opened on the surface of the pen cap 2, a first slide rod 15 is fixedly connected in the second slide groove 14, a first anti-collision block 16 is fixedly connected to the surface of the first slide rod 15, and a second spring 17 is fixedly connected between the first anti-collision block 16 and the pen cap 2. During operation, when the pen body 1 falls, one end of the pen cap 2 can be buffered and protected by the action of the first anti-collision block 16, the first slide rod 15 and the second spring 17 to avoid damage to the pen body 1.
[0024] Furthermore, a third slide groove 18 is provided on the surface of the pen body 1, and a second slide rod 19 is slidably connected in the third slide groove 18. A second anti-collision block 20 and a support block 21 are fixedly connected to the surface of the second slide rod 19, and a third spring 22 is fixedly connected between the support block 21 and the pen body 1. During operation, when the pen body 1 falls, the end away from the pen cap 2 can be buffered and protected by the second anti-collision block 20, the second slide rod 19, the third spring 22 and the support block 21 to avoid damage to the pen body 1.
[0025] Furthermore, the tail end of the pen body 1 is tapered, and the pen cap 2 is slidably connected to the pen body 1. During operation, the pen body 1 has a tapered tail end, so that when the pen cap 2 is removed, it can be put on the tail end of the pen to be fixed, thereby preventing the pen cap 2 from being lost.
[0026] The working principle of the utility model is as follows: when the pen cap 2 needs to be put on the pen body 1, the clamping rod 9 is extracted forward. At this time, under the action of the first spring 7, the first spring 7 will push the pressing block 4 upward, and the pressing block 4 will drive the card block 5 to move upward, and the pen cap 2 can be put on the pen body 1. At this time, the clamping rod 9 can be loosened. When the pen cap 2 is completely pushed to the bottom, the first correction line 12 is aligned with the second correction line 13, and the card block 5 will coincide with the card slot 6. Then, the clamping rod 9 squeezes the pressing block 4 downward, and the pressing block 4 will drive the card block 5 to move downward, so that the card block 5 is inserted into the card slot 6, thereby achieving the effect of stably fixing the pen cap 2 on the pen body 1. When the pen falls, the pen cap 2 will not be separated from the pen body 1, avoiding In order to avoid damage to the pen tip, when the pen cap 2 needs to be removed, it is only necessary to extract the clamping rod 9 upwards, at this time, the first spring 7 will drive the pressure block 4 to move upwards, and the pressure block 4 will drive the card block 5 to disengage from the card slot 6, and then the pen cap 2 can be removed. At the same time, when the pen body 1 falls, one end of the pen cap 2 can be buffered and protected under the action of the first anti-collision block 16, the first slide bar 15 and the second spring 17, and then the end away from the pen cap 2 can be buffered and protected under the action of the second anti-collision block 20, the second slide bar 19, the third spring 22 and the support block 21, so as to avoid damage to the pen body 1. Finally, the tail end of the pen body 1 is tapered, so when the pen cap 2 is removed, it can be fixed on the tail end of the pen to avoid loss of the pen cap 2.
