[0014] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-6A portable core marking device is characterized by comprising a marking device body 1, a guide component 2, a protective sleeve 3, and a connector 4. The guide component 2 is located on one side of the middle portion of the marking device body 1, and the protective sleeve 3 is located on one side of the guide component 2. The connector 4 is located at the side end of the marking device body 1, and the protective sleeve 3 is fitted onto one side of the marking device body 1. A connecting groove 101 is provided on the outer side of the marking device body 1, and guide grooves 102 are respectively provided on both sides of the connecting groove 101, with the guide grooves 102 on both sides being symmetrically mirrored.

[0015] Guide component 2 includes guide block 201, connecting rod 202, slide rod 203, positioning block 204, and first spring 205. The inner ends of both guide blocks 201 are fixedly connected to the connecting rod 202. The slide rod 203 is provided in the middle of the connecting rod 202. The positioning block 204 is provided on the side of the connecting rod 202 away from the guide block 201. One end of the positioning block 204 is fixedly connected to one end of the first spring 205, and the other end of the first spring 205 is fixedly connected to the connecting rod 202. By pulling the protective sleeve 3, the protective sleeve 3 can drive the slide rod 203 to move. Sliding along the groove of the connecting rod 202, during this process, because the end of the positioning block 204 away from the first spring 205 is spherical, the arc surface of the first positioning hole 2031 will squeeze the positioning block 204 and cause the first spring 205 to compress during the movement of the sliding rod 203, so that the positioning block 204 will separate from the first positioning hole 2031. When the sliding rod 203 moves to the third positioning hole 2033 and matches the positioning 204, the elastic force of the first spring 205 will cause the positioning block 204 to match the third positioning hole 2033, so that the protective sleeve 3 separates from the marking device body 1.

[0016] The outer wall of the guide block 201 can match the guide groove 102. A sliding groove 2021 is provided on the side of the connecting rod 202 adjacent to the slide rod 203. The inner wall of the sliding groove 2021 can match the slide rod 203. A positioning sliding hole 2022 is provided on the side of the connecting rod 202 away from the guide block 201. The positioning block 204 and the first spring 205 are both located inside the positioning sliding hole 2022. The outer wall of the positioning block 204 matches the positioning sliding hole 2022. A first positioning hole 2 is provided in the middle of the slide rod 203. 031, a second positioning hole 2032 is provided on one side of the slide rod 203, and a third positioning hole 2033 is provided on the other side of the slide rod 203. The end of the slide rod 203 adjacent to the third positioning hole 2033 is fixedly connected to the protective sleeve 3. The first positioning hole 2031, the second positioning hole 2032 and the third positioning hole 2033 have the same shape. The shape of the end of the positioning block 204 away from the first spring 205 is the same as the shape of the first positioning hole 2031, the second positioning hole 2032 and the third positioning hole 2033.

[0017] The connecting component 4 includes a fixed rod 401, a round rod 402, a round block 403, a limiting block 404, and a second spring 405. The end of the round block 403 is fixedly connected to the main body 1 of the marking device. The inner wall of the round block 403 is rotatably connected to one end of the fixed rod 401. A limiting block 404 is rotatably connected to the fixed rod 401 on one side adjacent to the round block 403. The end of the round rod 402 is fixedly connected to the main body 1 of the marking device. A limiting block 404 is provided on one side of the fixed rod 401 adjacent to the round rod 402. A second spring 405 is provided on one side of the limiting block 404. Rotating the protective sleeve 3 drives the sliding rod 203 to move circumferentially, which in turn drives the connecting rod 202 to move circumferentially. The connecting rod 202 then drives the guide... Block 201 moves circumferentially along guide groove 102. Guide block 201 drives fixed rod 401 to rotate along circular block 403 and circular rod 402. Fixed rod 401 can drive limiting block 404 and second spring 405 to move circumferentially. Since the end of limiting block 404 away from second spring 405 is spherical, during the circumferential movement of limiting block 404, after the arc surface of limiting hole 4031 contacts the spherical surface of limiting block 404, limiting block 404 drives second spring 405 to compress. When corresponding to the limiting hole 4031 at the corresponding position, limiting block 404 is affected by the elastic force of second spring 405 and matches the limiting hole 4031 at the corresponding position, thereby fixing the position of fixed rod 401.

[0018] The end of the fixed rod 401 away from the round rod 402 is fixedly connected to the guide block 201. The inner ring surface of the round block 403 is provided with multiple limiting holes 4031, which are distributed in an equal-angle ring. The side of the fixed rod 401 adjacent to the limiting block 404 is provided with a limiting sliding hole 4011. The limiting sliding hole 4011 is provided with a limiting block 404 and a second spring 405. The two ends of the second spring 405 are fixedly connected to the limiting block 404 and the fixed rod 401, respectively. The limiting block 404 can slide and connect with the inner wall of the limiting sliding hole 4011. The shape of the end of the limiting block 404 away from the second spring 405 is the same as the shape of the limiting hole 4031. The end of the limiting block 404 away from the second spring 405 matches the limiting hole 4031.

[0019] Specifically, when marking the rock core, pulling the protective sleeve 3 causes the sliding rod 203 to move. The sliding rod 203 slides along the groove of the connecting rod 202. During this process, because the end of the positioning block 204 away from the first spring 205 is spherical, the arc surface of the first positioning hole 2031 will squeeze the positioning block 204 during the movement of the sliding rod 203, causing the first spring 205 to compress, thus separating the positioning block 204 from the first positioning hole 2031. When the sliding rod 203 moves to the third positioning hole 2033 and matches the positioning 204, the elastic force of the first spring 205 causes the positioning block 204 to match the third positioning hole 2033, thus separating the protective sleeve 3 from the main body 1 of the marking device. Rotating the protective sleeve 3 causes the sliding rod 203 to move clockwise circumferentially, which in turn causes the connecting rod 202 to move circumferentially. The connecting rod 202 then causes the guide block 201 to move circumferentially along the guide groove 102. The block 201 drives the fixing rod 401 to rotate along the circular block 403 and the circular rod 402. The fixing rod 401 can drive the limiting block 404 and the second spring 405 to move circumferentially. Since the end of the limiting block 404 away from the second spring 405 is spherical, during the circumferential movement of the limiting block 404, after the arc surface of the limiting hole 4031 contacts the spherical surface of the limiting block 404, the limiting block 404 drives the second spring 405 to compress. When it corresponds to the limiting hole 4031 at the corresponding position, the limiting block 404 is affected by the elastic force of the second spring 405 and matches the limiting hole 4031 at the corresponding position, thereby fixing the position of the fixing rod 401. This allows the protective sleeve 3 to be placed at the rear end of the marking device body 1 at the marking end. Then, the rock core is marked through the marking end of the marking device. After that, the protective sleeve 3 is reset. The positioning block 204 matches the first positioning hole 2031, thereby fixing the protective sleeve 3.
