[0029] The surface of the mounting disc 1 is provided with a plurality of adjusting ring grooves 2 along the center-to-edge direction, adjusting straight grooves 3 are provided between adjacent adjusting ring grooves 2, and adjusting blocks 4 are slidably arranged in the adjusting ring grooves 2. The adjusting ring grooves 2 provide movable tracks for the adjusting blocks 4. By changing the position of the adjusting blocks 4 in different adjusting ring grooves 2, the diameter of the circular clamping space formed by the clamping tool 9 can be changed to adapt to screw bodies 6 of different diameters. The adjusting blocks 4 can slide along the circumferential direction in the adjusting ring grooves 2. When the adjusting blocks 4 are moved to different ring groove positions, the connected clamping tool 9 changes position to adapt to the diameter of the screw, according to the diameter measurement value of the screw body 6, manually move the adjusting block 4 to the appropriate adjusting ring groove 2 position in the path composed of the adjusting straight groove 3 and the adjusting ring groove 2, and then fix the adjusting block 4 to make the clamping tool 9 in a position that can accurately clamp the screw. The adjusting straight groove 3 serves as a transition channel for the adjusting block 4 to move between different adjusting ring grooves 2, facilitating the switching and adjustment of the adjusting block 4 between adjacent ring grooves. When the diameter adjustment range of the clamping tool 9 needs to be changed, the adjusting block 4 is first moved in the adjusting straight groove 3 and then enters the target adjusting ring groove 2. This process makes the adjustment of the tool to the screw diameter more convenient and accurate. In cooperation with the adjusting ring groove 2, the adjustment process of the tool when adapting to different screw diameters is more smooth and flexible, improving the adjustment accuracy and efficiency of the tool. The adjusting block 4 connects the mounting disc 1 and the L-shaped support shaft seat, and transmits the position change in the adjusting ring groove 2 and the adjusting straight groove 3 to the clamping tool 9, thereby adjusting the clamping space. After being fixed, the clamping tool 9 is stably supported.

[0030] The top surface of the adjusting block 4 is connected with an L-shaped support shaft seat 7, and the top end of the L-shaped support shaft seat 7 is connected with a clamping tool 9 through a shaft. The L-shaped support shaft seat serves as a bridge connecting the adjusting block 4 and the clamping tool 9, and provides a certain support height and angle for the clamping tool 9, so that the clamping tool 9 can clamp the screw body 6 at a suitable position and limit the movement of the clamping tool 9 in the horizontal and vertical directions.

[0031] A limiting assembly 8 is arranged between the side of the clamping tool 9 and the side of the L-shaped support shaft seat 7, the clamping tool 9 comprises an arc-shaped guide sleeve 901 and an arc-shaped adjusting shaft sleeve 902, the inner wall of the arc-shaped guide sleeve 901 abuts against the outer wall of the screw body 6, the inner wall of the arc-shaped guide sleeve 901 is provided with a positioning strip 10, the outer wall of the screw body 6 is provided with a positioning groove 11, the positioning strip 10 and the positioning groove 11 are in clearance fit, the clamping tool 9 directly contacts and clamps the screw body 6, the arc-shaped guide sleeve 901 and the arc-shaped adjusting shaft sleeve 902 are included, the accurate fixing of the screw body 6 and the screw body 6 of different heights are realized through the cooperation of the two, at the same time, the positioning strip 10 is used for limiting the screw body 6 in the horizontal direction, preventing the screw body 6 from shaking during tapping, the inner wall of the arc-shaped guide sleeve 901 abuts against the outer wall of the screw body 6, the positioning strip 10 in the arc-shaped guide sleeve 901 cooperates with the positioning groove 11 of the outer wall of the screw body 6 to realize the limiting in the horizontal direction, the arc-shaped adjusting shaft sleeve 902 is connected in the arc-shaped guide sleeve 901 through a damping spring 903, can be stretched and contracted in the vertical direction to adapt to the screw body 6 of different heights, and the downward pressure is applied to the screw body 6 through a pressing plate 904, further enhancing the stability of clamping, after the screw body 6 is placed in place, the arc-shaped guide sleeve 901 first contacts the screw body 6 and is preliminarily positioned through the positioning strip 10, then the arc-shaped adjusting shaft sleeve 902 is automatically adjusted in position under the action of the damping spring 903 according to the height of the screw body 6, finally, the pressure is applied through the pressing plate 904, so that the clamping tool 9 forms a stable clamping force on the screw body 6, the stability of the screw body 6 is maintained during tapping, through the unique structure design, the accurate limiting and stable clamping of the screw body 6 in the horizontal and vertical directions are realized, the screw body 6 of different diameters and heights can be adapted, the universality of the tool and the reliability of the clamping are improved, and the accuracy of tapping is effectively ensured.

The bottom surface of the arc-shaped guide sleeve 901 is provided with a bearing bottom plate 12. The damping spring 903 connects the arc-shaped guide sleeve 901 and the arc-shaped adjusting shaft sleeve 902, provides elastic buffering and self-adaptive adjustment capability for the up and down movement of the arc-shaped adjusting shaft sleeve 902 inside the arc-shaped guide sleeve 901, enables the clamping tool 9 to adapt to screw main bodies 6 of different heights, and to a certain extent, reduces the problem of excessive change of clamping force caused by height difference of the screw main body 6. When the height of the screw main body 6 is higher or lower than the standard height, the arc-shaped adjusting shaft sleeve 902 will move upward or downward correspondingly under the action of the damping spring 903. The damping spring 903 absorbs or releases energy through its elastic deformation, so that the arc-shaped adjusting shaft sleeve 902 can stably adjust the position. At the same time, in the adjustment process, the damping characteristic of the damping spring 903 can slow down the movement speed to avoid impact caused by rapid movement. The bearing bottom plate 12 is located at the bottom surface of the arc-shaped guide sleeve 901, used for bearing the weight of the screw main body 6 and uniformly dispersing the weight to the mounting disc 1, and to a certain extent, plays a supporting role in the vertical direction to the screw main body 6, enhances the overall stability of the clamping tool 9. When the screw main body 6 is placed in the clamping tool 9, its weight is transmitted to the bearing bottom plate 12 through the arc-shaped guide sleeve 901. The bearing bottom plate 12 is in close contact with the mounting disc 1, uniformly distributes the weight on the surface of the mounting disc 1, prevents the tool from deforming or the screw main body 6 from being displaced due to excessive local stress, and in the whole tapping process, the bearing bottom plate 12 always bears the weight of the screw main body 6 and stably transmits it to the mounting disc 1, jointly acts with other parts of the clamping tool 9, maintains the stable clamping state of the screw main body 6, ensures the position stability of the screw main body 6 in static or dynamic stress conditions in the tapping process, enhances the overall stability of the clamping tool 9, effectively disperses the weight of the screw main body 6, reduces the possibility of tool deformation or screw main body 6 displacement caused by gravity, and improves the accuracy and reliability of tapping.

The limiting shaft seat 801 of the limiting assembly 8 is welded to the outer wall of the arc-shaped adjusting shaft sleeve 902, and the limiting groove 804 is arranged outside the end of the shaft connection of the pressing plate 904 and the arc-shaped adjusting shaft sleeve 902. The pressing plate 904 is connected to the top end of the arc-shaped adjusting shaft sleeve 902, and is used for applying downward pressure to the screw body 6, thereby enhancing the clamping force of the clamping tool 9 on the screw body 6, and making the screw body 6 more stable during the tapping process, and less likely to displace or shake. Through the shaft connection structure, the pressing plate 904 can rotate within a certain angle range, so as to better contact the top of the screw body 6. When an external force is applied, such as through bolt fastening or the like, the pressing plate 904 transmits the pressure to the screw body 6, and cooperates with the clamping force of the arc-shaped guide sleeve 901 and the arc-shaped adjusting shaft sleeve 902 to firmly fix the screw body 6 in the clamping tool 9. After the screw body 6 is placed in the clamping tool 9 and the position of the arc-shaped adjusting shaft sleeve 902 is adjusted, downward pressure is applied to the pressing plate 904, so that the pressing plate 904 is in close contact with the top of the screw body 6 and generates sufficient clamping force. During the tapping process, the pressure state is continuously maintained to prevent the screw body 6 from displacing due to the action force of the tapping tool, thereby significantly enhancing the clamping force of the clamping tool 9 on the screw body 6, improving the stability of the screw body 6 during the tapping process, effectively reducing the tapping error caused by insufficient clamping force, and ensuring the tapping accuracy and quality.

The connecting shaft seat 13 is movably connected to the top end of the L-shaped support shaft seat 7, so that the arc-shaped guide sleeve 901 can be rotated and adjusted within a certain angle range about the shaft, so as to better adapt to the shape and position of the screw body 6, improve the flexibility and accuracy of clamping, and through the shaft connection structure, the arc-shaped guide sleeve 901 can rotate within a certain range relative to the L-shaped support shaft seat. When the shape or position of the screw body 6 deviates, the arc-shaped guide sleeve 901 can automatically adjust the angle, so that the inner wall is better matched with the outer wall of the screw body 6, and more accurate clamping is realized. When the screw body 6 is placed in the clamping tool 9, the arc-shaped guide sleeve 901 is connected to the L-shaped support shaft seat through the connecting shaft seat 13, and can automatically adjust the angle according to the actual situation of the screw body 6, so that the positioning strip 10 and the positioning groove 11 can be smoothly matched. During the tapping process, the arc-shaped guide sleeve 901 can also be automatically adjusted according to the possible slight angle change of the screw body 6, so as to maintain the stability of clamping, improve the adaptability of the clamping tool 9 to the shape and position deviation of the screw body 6, enhance the flexibility and accuracy of clamping, and help to further improve the tapping accuracy and quality, and reduce the tapping problems caused by the non-ideal installation position of the screw body 6.

[0035] The limiting assembly 8 comprises a limiting shaft seat 801 and an L-shaped limiting support arm 802. The limiting shaft seat 801 is welded to the outer wall of the arc-shaped guide sleeve 901. The limiting shaft seat 801 is connected with the end of the L-shaped limiting support arm 802 through a shaft. The end of the L-shaped limiting support arm 802 is connected with a T-shaped limiting buckle 803. A limiting groove 804 is formed in the outer side of the L-shaped support shaft seat 7. The T-shaped limiting buckle 803 is clamped with the limiting groove 804. The limiting assembly 8 limits the movement of the clamping tool 9. The relative position between the clamping tool 9 and the L-shaped support shaft seat is prevented from changing due to external force during the tapping process, so as to affect the clamping stability and tapping precision of the screw main body 6. When the clamping tool 9 is subjected to external force, the limiting assembly 8 limits the relative movement direction to keep the stability of the clamping tool 9. After the installation and adjustment of the clamping tool 9 are completed, the T-shaped limiting buckle is clamped into the corresponding limiting groove 804. During the tapping process, no matter from which direction the external force is received, the limiting assembly 8 can prevent the excessive displacement of the clamping tool 9 relative to the L-shaped support shaft seat, so as to ensure that the screw main body 6 is always in a stable clamping state. The stability of the clamping tool 9 during the tapping process is effectively improved. The tapping error caused by unstable clamping is reduced. The tapping precision and quality are ensured. The reliability and durability of the tool are improved.
