[0007] Preferably, a guide block is provided on one side of the protective sleeve, and a guide groove is embedded in the inner wall of the protective shell, with the guide block and the guide groove being slidably connected.

[0008] Preferably, one end of the protective sleeve is provided with a traction rope, and one side of the red light pen body is provided with a switch.

[0009] Preferably, one end of the red light pen body is provided with a handle, and the surface of the handle is provided with anti-slip texture.

[0010] Preferably, one end of the handle is provided with a hanging rope, and the hanging rope is fixedly connected to the handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The protective shell, protective sleeve, interface, card slot, storage slot, spring and buckle are designed to protect the interface of the red light pen. The protective sleeve is inserted into the protective shell and the buckle is inserted into the card slot to fix the protective sleeve in place, thereby protecting the interface.

[0013] 2. The sealing groove and sealing gasket ensure a tight seal between the protective sleeve and the protective shell. When the protective sleeve is inserted into the protective shell, the sealing gasket will be inserted into the sealing groove, improving the sealing performance of the structure, preventing dust from entering, and making it safer to use.

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: an easy-to-use fiber optic red light pen, including a red light pen body 1 and a protective shell 2. One end of the red light pen body 1 is provided with the protective shell 2, and the inside of the protective shell 2 is provided with a protective sleeve 3. The protective sleeve 3 and the protective shell 2 are fixed by interlocking. One end of the red light pen body 1 is provided with an interface 4. One side of the protective shell 2 is provided with a slot 5. One side of the protective sleeve 3 is provided with a storage groove 6. The inside of the storage groove 6 is provided with a spring 7. The spring 7 and the storage groove 6 are fixedly connected. The inside of the storage groove 6 is provided with a buckle 8. The buckle 8 and the storage groove 6 are slidably connected. The buckle 8 and the slot 5 are fixed by engaging.

[0020] In this embodiment, after using the easy-to-use fiber optic red light pen, the protective sleeve 3 is inserted into the protective shell 2. The buckle 8 is squeezed into the storage groove 6 by the inner wall of the protective shell 2, and at the same time, the spring 7 is compressed. When the buckle 8 moves to the position of the slot 5, the buckle 8 will be locked into the slot 5 under the reaction force of the spring 7, thus completing the fixation. When it is needed, simply press the buckle 8 to pull the protective sleeve 3 out from the inside of the protective shell 2, exposing the interface 4, and it can be used normally. This achieves the protection of the interface 4 and improves the service life of the red light pen.

[0021] Specifically, one end of the protective sleeve 3 is provided with a sealing groove 9, the inside of the protective shell 2 is provided with a sealing gasket 10, the sealing gasket 10 and the sealing groove 9 are fixed by interlocking, one side of the protective sleeve 3 is provided with a guide block 11, the inner wall of the protective shell 2 is provided with a guide groove 12, the guide block 11 and the guide groove 12 are slidably connected, one end of the protective sleeve 3 is provided with a traction rope 13, one side of the red light pen body 1 is provided with a switch 14, one end of the red light pen body 1 is provided with a handle 15, the surface of the handle 15 is provided with anti-slip texture 16, one end of the handle 15 is provided with a hanging rope 17, the hanging rope 17 and the handle 15 are fixedly connected.

[0022] In this embodiment, the sealing groove 9 and sealing gasket 10 achieve a seal between the protective sleeve 3 and the protective shell 2. When the protective sleeve 3 is inserted into the interior of the protective shell 2, the sealing gasket 10 will be inserted into the sealing groove 9, improving the sealing performance of the structure, preventing dust from entering, and making it safer to use. The guide block 11 and guide groove 12 can guide the protective sleeve 3, so that when it is inserted into the interior of the protective shell 2, the buckle 8 can be accurately engaged into the slot 5, making it more convenient to use. The traction rope 13 is used to fix the protective sleeve 3 and prevent it from falling. The switch 14 is used to turn the device on and off. The hanging rope 17 provides convenience for placing the device.
