Furthermore, the excessive repetition of the chain or link structure can lead to excessive wear, structural instability, and bulky shape. They are inconvenient to use in confined spaces, especially in underwater environments, where they are subject to significant external forces. Summary of the Invention

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 6 As shown, a bamboo-joint telescopic mechanism includes an outer frame 1, a feeding assembly 2, a propulsion assembly 3, and bamboo-joint telescopic rods 4. The outer frame 1 includes a feeding chamber 11 and a propulsion chamber 12. The feeding chamber 11 is a detachable structure. The side end of the propulsion chamber 12 has a rod outlet opening 13. An electric telescopic rod 14 is also installed on the other side end of the propulsion chamber 12. A locking rod 15 is installed at the end of the electric telescopic rod 14. The feeding assembly 2 is installed inside the feeding chamber 11, the propulsion assembly 3 is installed inside the propulsion chamber 12, and the bamboo-joint telescopic rods 4 are evenly distributed inside the feeding chamber 11.

[0021] In this embodiment, the feeding assembly 2 includes a rack 21 and a feeding block 22. A mounting frame 23 is provided inside the feeding bin 11. The rack 21 is fixedly mounted on the mounting frame 23. A guide rod 24 is also fixedly mounted on the mounting frame 23. The feeding block 22 is slidably mounted on the rack 21 and the guide rod 24. A motor 25 is installed inside the feeding block 22. A gear 26 that meshes with the rack 21 is installed at the output end of the motor 25. A telescopic push rod 27 that cooperates with the front end recess of the bamboo joint telescopic rod 4 is also installed on the side end of the feeding block 22.

[0022] In this embodiment, the propulsion assembly 3 includes a sliding propulsion seat 31 and a second motor 32. The second motor 32 is installed inside the propulsion chamber 12, and a lead screw 33 is also installed inside the propulsion chamber 12. A second gear 34 connected to the lead screw 33 via a synchronous belt is installed at the output end of the second motor 32. A propulsion guide rail 35 is also provided inside the propulsion chamber 12. The sliding propulsion seat 31 is threaded onto the lead screw 33 and is also slidably disposed on the propulsion guide rail 35. An electromagnetic coil 38 and a battery 39 are installed inside the propulsion chamber 12 via a first baffle 36 and a second baffle 37.

[0023] It should be noted that the battery 39 powers the entire mechanism, and the sliding propulsion seat 31 and the bamboo-joint telescopic rod... The sliding propulsion seat 31 penetrates the propulsion chamber 12 and cooperates with the nearest bamboo-joint telescopic rod 4. The first baffle 36 is made of non-ferrous material, while the second baffle 37 on the other five sides is made of iron material, in order to avoid electromagnetic damage to surrounding electrical appliances.

[0024] In this embodiment, an iron block 42 is installed in one opening of the bamboo joint telescopic rod 4 via a spring 41, and a connecting hole 44 is provided on the other side of the bamboo joint telescopic rod 4.

[0025] In this embodiment, the bamboo-joint telescopic rod 4 is a split hollow structure, with its front and rear ends working together to effectively reduce its average density in water when working in underwater environments.

[0026] In this embodiment, the locking hole 43 cooperates with the locking rod 15.

[0027] Working process and principle: The output end of motor 2 32 drives the lead screw 33 to rotate via gear 2 34, which in turn drives the sliding propulsion seat 31 to move, thereby driving the nearest bamboo joint telescopic rod 4 to move. The electromagnetic coil 38 works to generate magnetic force to move the iron block 42 inside the foremost bamboo joint telescopic rod 4, in preparation for connecting to the next bamboo joint telescopic rod 4. After the bamboo joint telescopic rod 4 contacts the previous bamboo joint telescopic rod 4, the electromagnetic coil 38 is turned off, and the iron block 42 is pushed into the connecting hole 44 of the connected bamboo joint telescopic rod 4 by the spring 41, so that the two are connected. Immediately, the end of the electric telescopic rod 14 drives the locking rod 15 to retract, and the output end of the motor 25, via gears... 1. 26 drives the feeding block 22 to move on the rack 21, and enters the front end concave hole of the bamboo joint telescopic rod 4 through the top pushing end of the telescopic push rod 27, driving the corresponding bamboo joint telescopic rod 4 to perform supplementary feeding, and then repeating the above pushing and locking movements to complete the extension action of all bamboo joint telescopic rods 4 in the rod opening 13, and the retraction action is the reverse operation of the extension action.

[0028] Based on the above, this invention, by setting a feeding component 2 and a propulsion component 3 inside the outer frame 1, and cooperating with the electric telescopic rod 14, allows the split bamboo-joint telescopic rod 4 to extend and retract sufficiently within the outer frame 1. It remains applicable in narrow environments, is easy to replace and maintain, has a simple and stable structure that is easy to fix and separate, and offers great flexibility in changing its maximum telescopic length. It has great potential for development in construction, industry, transportation, and other fields. Furthermore, the bamboo-joint telescopic rod 4 has a split hollow structure, which can effectively reduce its average density in water and increase buoyancy to reduce external interference in water when dealing with underwater working environments.

[0029] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
