[0002] A bit with a floating space means that during the working process, the bit can perform small floating or offset within a certain range to adapt to the unevenness or changes of the workpiece surface. The bit usually refers to a part of a tool or equipment for converting rotational kinetic energy into linear kinetic energy. In many industrial and manufacturing fields, bits are widely used in tasks such as thread cutting and hole machining.

[0003] After retrieval, the Chinese patent document with the publication number CN214081174U discloses a bit, including a bit body. Both ends of the bit body are provided with bit ends. One end of the bit end is fixedly connected with a connecting stud. One end of the connecting stud is fixedly connected with a clamping block. The outer surface of the connecting stud is provided with connecting teeth, and the connecting teeth are fixedly connected with the bit body. The upper surface and the lower surface of the clamping block are both provided with clamping bolts. One end of the clamping bolt is fixedly connected with a spring, and the spring is fixedly connected with the clamping block. The inside of the bit body is wrapped with a connecting column, and both ends of the connecting column are fixedly connected with connecting hooks; by designing the detachable bit ends installed at both ends of the bit body and the connecting stud, clamping block and clamping bolt at one end of the bit end, it is convenient to disassemble and replace the bit end and the connecting end, effectively avoiding the problem that it cannot be replaced after being worn during long-term use, resulting in inconvenience and cost waste.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1-2 , an embodiment provided by the present utility model: A bit with a floating space includes a placing ring 1. The left side inside the placing ring 1 is slidably connected with a mounting seat 2. First, the mounting seat 2 is installed in a suitable position. The outer part of the placing ring 1 is threadedly connected with an inner collar 7. A card slot 8 is opened at the top of the inner collar 7. The right end of the mounting seat 2 is fixedly connected with a clamping plate 3. The right end of the clamping plate 3 is fixedly connected with a bracing plate 4. The outer part of the clamping plate 3 is slidably connected to the inner wall of the card slot 8. At this time, the clamping plate 3 is in contact with the inner wall of the card slot 8.

[0028] A spring 5 is sleeved on the right side outside the placing ring 1. One end of the spring 5 is fixedly connected to the outside of the placing ring 1, and the other end of the spring 5 is fixedly connected to the outside of the inner collar 7. A square chute 6 is opened at the top of the placing ring 1. The outer part of the clamping plate 3 is slidably connected to the inner wall of the square chute 6. The clamping plate 3 is forced to slide downward on the inner wall of the square chute 6 and press the bracing plate 4. At the same time, the spring 5 is compressed by force. The right end of the placing ring 1 is fixedly connected with a head. When the spring 5 is compressed by force, it will absorb the external force, and the head is forced to move to the right;

[0029] Refer to Figures 3-4, a limiting component is arranged outside the inner sleeve ring 7. The limiting component includes a rotating sleeve ring 9. The inside of the rotating sleeve ring 9 is rotatably connected to the outside of the inner sleeve ring 7. Then, rotate the rotating sleeve ring 9 according to the floating requirement. A convex plate 10 is fixedly connected to the inner wall of the rotating sleeve ring 9. The convex plate 10 presses against the top of the clamping plate 3. At the same time, the convex plate 10 will separate from the top of the clamping plate 3 during rotation. At this time, the clamping plate 3 moves to the left under the reaction force of the spring 5. A limiting column 11 is fixedly connected to the right end of the rotating sleeve ring 9. When the rotating sleeve ring 9 rotates, it will drive the inner convex plate 10 and the right-side limiting column 11 to rotate.

[0030] A connecting ring 12 is fixedly connected to the right end of the inner sleeve ring 7. A limiting groove 13 is formed in the outer left side of the connecting ring 12. The bottom of the convex plate 10 is in contact with the top of the clamping plate 3. The outside of the limiting column 11 is slidably connected to the inner wall of the limiting groove 13. At this time, the limiting column 11 will rotate along the inner wall of the limiting groove 13. At this time, the connecting ring 12 will move to the left as the placing ring 1 moves. At this time, the floating position of the placing ring 1 can be changed to meet the requirements of the floating amount of the locking mechanism for the assembly of some electronic products. When the limiting column 11 is engaged with the bottom of the limiting groove 13, the rotating sleeve ring 9 can be fixed, and then it can be used normally.

[0031] Working principle: First, install the mounting seat 2 in a suitable position. At this time, the clamping plate 3 is in contact with the inner wall of the card slot 8. The convex plate 10 presses against the top of the clamping plate 3. The clamping plate 3 is forced to slide downward on the inner wall of the square chute 6 and presses against the abutting plate 4. At the same time, the spring 5 is compressed by force. While the spring 5 is compressed by force, it will absorb the external force, and the end head moves to the right under force. Then, rotate the rotating sleeve ring 9 according to the floating requirement. When the rotating sleeve ring 9 rotates, it will drive the inner convex plate 10 and the right-side limiting column 11 to rotate. At this time, the limiting column 11 will rotate along the inner wall of the limiting groove 13. At the same time, the convex plate 10 will separate from the top of the clamping plate 3 during rotation. At this time, the clamping plate 3 moves to the left under the reaction force of the spring 5. At this time, the connecting ring 12 will move to the left as the placing ring 1 moves. When the limiting column 11 is engaged with the bottom of the limiting groove 13, the rotating sleeve ring 9 can be fixed, and then it can be used normally.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
