Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The clamping mechanism includes a third support column 11 movably mounted on the side end of the second telescopic column 8 away from the second support column 6, the third support column 11 is fixedly connected to the fixed column 16, the fixed column 16 is fixedly connected to the fixed box 13, the top end of the fixed box 13 is fixedly mounted with a motor 17, the end of the motor 17 away from the fixed box 13 is rotatably mounted with a gear 23, the gear 23 is engaged with a first rack 19 and a second rack 31, the bottom of the first rack 19 is fixedly mounted with a second splint 15, the inner wall surface of the second splint 15 is fixedly mounted with a first airbag 21, the bottom of the second rack 31 is fixedly mounted with a first splint 14, the inner wall surface of the first splint 14 is fixedly mounted with a second airbag 22, the bottom of the fixed box 13 is fixedly mounted with a rotating shaft 30, the inside of the fixed box 13 is fixedly mounted with a blower 18, the bottom of the fixed box 13 is fixedly connected to an air chamber 20, and the bottom of the air chamber 20 is connected to the first airbag 21 and the second airbag 22.
[0025] See Figure 4 A wire 12 is passed through the inside of the third support column 11, one end of the wire 12 is fixedly connected to the motor 17, and the end of the wire 12 away from the motor 17 is connected to the distribution box 2. The wire 12 is protected inside the third support column 11, reducing damage to the wire 12 due to external environmental factors and extending the service life of the wire 12.
[0026] See Figure 3 A connecting tube 28 is fixedly installed on the top of the first telescopic column 4, and a second thread 27 is provided on the outer wall of the connecting tube 28. A first ball head 25 is fixedly installed on the bottom of the first support column 5, and a third threaded cap 24 is installed on the outer wall of the first support column 5. A first thread 26 is provided on the inner wall of the third threaded cap 24. The first ball head 25 is movably installed inside the connecting tube 28. The first ball head 25 can rotate freely inside the connecting tube 28, thereby allowing the first support column 5 to be adjusted at multiple angles, thereby improving its adaptability and versatility.
[0027] See Figure 6 The side of the second support column 6 away from the first support column 5 is fixedly mounted with a third thread 32. The side of the second telescopic column 8 closer to the second support column 6 is fixedly mounted with a second ball head 33. The second ball head 33 is movably mounted within the third thread 32. A first threaded cap 7 is movably mounted on the outer wall of the second telescopic column 8. The first threaded cap 7 is threadedly connected to the third thread 32. When the angle of the second telescopic column 8 is adjusted to the desired position, the first threaded cap 7 is rotated to tightly connect it with the third thread 32, thereby securing the second telescopic column 8. This threaded connection ensures that the second telescopic column 8 remains stably in place after being adjusted to the desired angle, preventing accidental displacement or shaking during operation.
[0028] See Figure 6A fourth thread 34 is fixedly installed on the side of the second telescopic column 8 away from the second support column 6, a third ball head 35 is fixedly installed on the top of the third support column 11, and the third ball head 35 is movably installed inside the fourth thread 34. A second threaded cap 9 is movably installed on the outer wall of the third support column 11. The second threaded cap 9 is threadedly connected to the fourth thread 34. The adjustment and fixing process can be completed only by rotating the second threaded cap 9. No complicated tools or equipment are required. The entire connection structure is compact, occupies little space, is suitable for various working environments, and improves work efficiency.
[0029] See Figure 1 A second fixing hole 36 is opened on the outer wall of the first telescopic column 4, and a first fixing hole 29 is opened on the outer wall of the second telescopic column 8. The lengths of the first telescopic column 4 and the second telescopic column 8 can be quickly adjusted to further expand the moving range of the clamping mechanism to ensure stability and precision.
[0030] See Figure 1 A rotating shaft 30 is rotatably mounted at the bottom of the base 1, and a rotating wheel 10 is fixedly mounted on the rotating shaft 30. When the rotating wheel 10 contacts the ground, the entire device can be moved by rotating the rotating wheel 10, which is particularly useful when the device needs to be frequently moved or transferred from one place to another.
[0031] See Figure 1-Figure 2 The first airbag 21 and the second airbag 22 are made of rubber. The first airbag 21, the second airbag 22 and the outer wall of the rotating wheel 10 are all provided with an integrally formed anti-slip pattern. The rubber material itself has a certain friction coefficient, and the integrally formed anti-slip pattern further increases the surface roughness, thereby increasing the friction between the contact surface and effectively preventing sliding or accidental movement.
[0032] Working principle: When it is necessary to clamp mechanical parts, start the motor 17 to drive the gear 23 to rotate, and the gear 23 engages with the first rack 19 and the second rack 31, so that the first rack 19 and the second rack 31 respectively drive the second clamping plate 15 and the first clamping plate 14 to move in phase, thereby clamping the mechanical parts. At the same time, start the blower 18, and the blower 18 sends gas into the air chamber 20. The gas is then sent into the first air bag 21 and the second air bag 22 by the air chamber 20 for inflation, further increasing the clamping force of the clamping mechanism on the mechanical parts. If it is necessary to move the clamped mechanical parts, the first threaded cap 7, the second threaded cap 9 and the third threaded cap 24 can be easily adjusted to the desired position. If the adjustment position length is limited, press the card ball in the first fixing hole 29 and the second fixing hole 36 to adjust the length of the first telescopic column 4 and the second telescopic column 8, thereby expanding the moving range of the entire clamping device and improving the working range.
