When the new drill bit is replaced, the slider 4 is slidably connected with the slide groove 3. When the slider 4 slides in the slide groove 3, the position of the housing 7 can be adjusted through the connecting block 5 and the bracket 6, so that the position of the top screw 13 is adjusted, so that one end of the top screw 13 is pressed against the screw mouth of the installation tube 1, and the pull ring 14 is loosened, so that the spring spring 11 generates a retraction force, so that the top screw 13 is screwed back into the installation tube 1 to replace the new drill bit. The drill bit is fixed so that when the drill bit is loaded and unloaded, the loading and unloading of the drill bit can be made more convenient and quick by operating the convenient pull ring loading and unloading mechanism; the clockwork spring 11 is also called a (winding) spring, which refers to a spring whose spiral line is in one plane. The spring is a spring in which the material is wound into a plane spiral shape. One end of the spring is fixed, and after the other end is subjected to a torque, the material is subjected to a bending moment, resulting in bending elastic deformation, so that the spring is twisted in its own plane; the torsional force of the clockwork spring 11 is relatively strong, so that the top screw 13 can be screwed into the mounting tube 1, and the top screw 13 is used for fixing, and most of them are shaft holes, and the shaft is supported by the top screw 13 to prevent it from moving back and forth.

[0021] In one aspect of this embodiment, the card slot 17 fits with the outer shell 7, enabling the card holder 6 to better hold and fix the outer shell 7. When pulling the pull ring 14, due to the setting of the finger groove 15, the operator's hand can fit better with the pull ring 14, so that the pull ring 14 can be pulled more easily. When it is necessary to screw out the setscrew 13 from the installation cylinder 1, pulling the pull ring 14 can make the connecting line 12 pass through the extension slot 16 and be pulled out to the outside of the outer shell 7, thus causing the clockwork spring 11 to generate a torsional force. Then, a new drill bit can be inserted into the installation slot 18 for drill bit replacement.

[0022] In one aspect of this embodiment, through the setting of the protective frame 19, the convenient pull ring loading and unloading mechanism can be covered and protected. Through the setting of the rubber pad 20, when one side of the protective frame 19 is collided, the rubber pad 20 can absorb the vibration, so that the protective frame 19 can better protect the convenient pull ring loading and unloading mechanism.

[0023] The working principle of the present utility model: When this pull ring device for loading and unloading the lithium - battery rail drilling bit is in use, when it is necessary to replace the drill bit, the pull ring 14 can be pulled. When pulling the pull ring 14, due to the setting of the finger groove 15, the operator's hand can fit better with the pull ring 14. Pulling the pull ring 14 can make the connecting line 12 pass through the extension slot 16 and be pulled out to the outside of the outer shell 7, thus causing the clockwork spring 11 to generate a torsional force. Due to the clockwork spring 11 being arranged in the wire groove 10 and fixedly connected to the wire reel 9, the wire reel 9 being fixedly connected to the rotating shaft 8, the rotating shaft 8 being rotatably connected to the outer shell 7, and the wire reel 9 being fixedly connected to the setscrew 13, when pulling the clockwork spring 11, the wire reel 9 can be rotated, driving the setscrew 13 to be screwed out from the installation cylinder 1, so that the drill bit can be taken out from the installation slot 18 in the installation cylinder 1. Then, a new drill bit is inserted into the installation slot 18 to replace the new drill bit. When the new drill bit is replaced, due to the slider 4 being slidably connected to the chute 3, when the slider 4 slides in the chute 3, the position of the outer shell 7 can be adjusted through the connecting block 5 and the card holder 6, thereby adjusting the position of the setscrew 13, so that one end of the setscrew 13 abuts against the screw port of the installation cylinder 1. Loosen the pull ring 14, causing the clockwork spring 11 to generate a retraction force, so as to screw the setscrew 13 back into the installation cylinder 1 to fix the replaced new drill bit. Through the setting of the protective frame 19, the convenient pull ring loading and unloading mechanism can be covered and protected. Through the setting of the rubber pad 20, when one side of the protective frame 19 is collided, the rubber pad 20 can absorb the vibration.
