In addition, the number of clamping jaws 9 is at least 3, and the specific number can be set according to needs; the annular tooth groove structure can increase the friction resistance between the slide 10 and the first gear 8, so as to achieve the purpose of driving the rotation of multiple first gears 8 when the slide 10 slides; the second telescopic rod 5 plays the role of supporting the rotating part, which can ensure that the adjacent rotating parts of the device maintain relative positions when not working and will not rotate excessively due to the hinge; and when the rotating part rotates through the hinge, it will drive the telescopic end of the second telescopic rod 5 to telescope, thereby achieving the effect of bending the adjacent rotating parts; the telescopic end of the third telescopic rod 13 can drive the tooth plate 12 to slide, thereby achieving flexible angular rotation of the second gear 11, the rotating plate 3, the mechanical arm part 4 and the clamping assembly.

[0037] Furthermore, the robotic arm component 4 includes at least three rotating parts.

[0038] Working principle: when using the clamping jaw 9, by rotating the handle 17 at the corresponding position, the rotating rod 16 is driven to rotate. When the rotating rod 16 rotates, the sliding groove of the rotating rod 16 limits the telescopic sliding of the telescopic end of the fourth telescopic rod 14, and the gas in the first telescopic rod 401 enters the corresponding fourth telescopic rod 14. The telescopic end of the first telescopic rod 401 retracts into the first telescopic rod 401 part, driving the slide plate 10 to slide. The tooth groove on the outside of the slide plate 10 drives the first gear 8 to rotate, and the first gear 8 drives the clamping jaw 9 to rotate, thereby realizing the clamping action of the clamping jaw 9 and adjusting the mechanical arm. When the mechanical arm component 4 is rotated, the handle 17 at the corresponding position is rotated, and the above operation is repeated to realize the telescopic sliding of the telescopic end of the corresponding fourth telescopic rod 14. The gas in the second telescopic rod 5 enters the corresponding fourth telescopic rod 14, and the telescopic end of the second telescopic rod 5 is retracted into the second telescopic rod 5, thereby realizing the bending action of the mechanical arm component 4. When the mechanical arm component 4 and the clamping assembly are rotated, the handle 17 at the corresponding position is rotated, and the above operation is repeated to realize the telescopic sliding of the telescopic end of the corresponding fourth telescopic rod 14. The gas in the third telescopic rod 13 enters the corresponding fourth telescopic rod 14. In the telescopic rod 14, the telescopic end of the third telescopic rod 13 is retracted into the third telescopic rod 13 part, and the telescopic end of the third telescopic rod 13 drives the tooth plate 12 to slide, and the tooth plate 12 is engaged with the second gear 11 to drive the second gear 11 to rotate, and the second gear 11 drives the rotating plate 3 to rotate, thereby realizing the rotation action of the mechanical arm component 4 and the clamping assembly. When installing the clamping claw 9, the first gear 8 is placed between the fixed plates 7 at the corresponding position and pressed. One side of the limit block 19 is forced into the storage groove of the first gear 8. When the first gear 8 enters between the fixed plates 7, the limit The thrust of the positioning spring 18 drives the limit block 19 to slide in the opposite direction and is fixed in the limit groove between the fixed plates 7, thereby realizing the installation of a single clamping jaw 9. When encountering a building block that is difficult to clamp, the number of clamping jaws 9 is increased, thereby increasing the contact area with the building block and reducing the difficulty of operation. When removing a single clamping jaw 9, pull the clamping jaw 9 to be removed with force, and the limit block 19 is forced to slide toward the storage groove of the first gear 8, releasing the limit of the clamping jaw 9, thereby realizing the removal of a single clamping jaw 9. The removed clamping jaw 9 can be stored in the drawer of the base 1 to reduce the occupied space.
