[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] Please refer to the attached Figure 1-Figure 4 A transmission shaft assembly that is easy to maintain includes a transmission shaft body 1, a universal end head 2 is provided on the transmission shaft body 1, a connecting rod 3 is provided on the universal end head 2, a plug-in rod 4 is plugged into the inside of the connecting rod 3, a clamping component for fixing the plug-in rod 4 is provided on the connecting rod 3, and a fixing component for locking the clamping component is provided on the connecting rod 3.

[0025] The specific operation process of the utility model is as follows: connect the connecting rod 3 on the universal end head 2 at both ends of the transmission shaft body 1 to the plug-in rod 4, insert the plug-in rod 4 into the connecting rod 3, fix the inserted plug-in rod 4 by the clamping assembly, and then fix the clamping assembly by the fixing assembly, so as to realize the installation of the transmission shaft body 1, and the reverse operation can be realized when disassembling, so that the transmission shaft body 1 can be conveniently disassembled and installed.

[0026] Please refer to Figure 2-Figure 4 Guide grooves 14 are provided on both sides of the connecting rod 3 , and guide blocks 13 are fixedly installed on both sides of the plug-in rod 4 , and the guide blocks 13 are plugged into the guide grooves 14 .

[0027] When the plug-in rod 4 is inserted into the connecting rod 3, the guide block 13 is aligned with the guide groove 14 and then the plug-in rod 4 is pushed, which can limit the linear movement of the plug-in rod 4 and prevent the subsequent clamping rod 8 from being unable to align with the clamping groove 7. At the same time, the guide block 13 and the guide groove 14 also limit the insertion depth of the plug-in rod 4 to prevent the plug-in rod 4 from being inserted too deep and causing the clamping rod 8 to be unable to be inserted into the clamping groove 7.

[0028] Please refer to Figure 2-Figure 4 The clamping assembly includes a plurality of limiting blocks 6, which are staggered on the connecting rod 3 and fixedly mounted on the connecting rod 3. A clamping rod 8 is slidably connected inside the limiting block 6, and a pulling block 9 is fixedly mounted on the upper end of the clamping rod 8. A spring 10 is sleeved on the clamping rod 8, and the spring 10 is arranged inside the limiting block 6. A plurality of clamping grooves 7 are provided on the plug-in rod 4, and a plurality of clamping grooves 7 are staggered on the plug-in rod 4, and a clamping rod 8 is inserted into the clamping groove 7.

[0029] The limiting blocks 6 are staggered on the connecting rod 3, and each limiting block 6 is in a different position. When the plug-in rod 4 is inserted into the inside of the connecting rod 3, the plug-in rod 4 will press on each clamping rod 8 in turn. When it presses on which clamping rod 8, the pulling block 9 will be pulled upward, and the pulling block 9 will drive the clamping rod 8 to rise. A clamping block will be set at the lower end of the clamping rod 8 to pull the limiting block 6 to compress the spring 10, and then push the plug-in rod 4 forward. After the plug-in rod 4 passes over the clamping rod 8, the pulling block 9 is released. After the spring 10 has no upward pulling force, the spring 10 will drive the clamping rod 8 to rebound and reset and descend, and the clamping rod 8 will press on the plug-in rod 4. On the surface, the spring 10 has not fully recovered yet and is still in a compressed state. When the plug-in rod 4 passes over the multiple clamping rods 8 in turn and is pushed to the bottom of the connecting rod 3, the multiple clamping rods 8 will be above the multiple clamping grooves 7 opened on the plug-in rod 4. At this time, the clamping rod 8 will be inserted into the clamping groove 7 under the thrust of the spring 10. At this time, the spring 10 is fully recovered, and the multiple clamping rods 8 are inserted into the clamping groove 7 at the same time to fix the plug-in rod 4. The advantage of staggered arrangement of the clamping rods 8 and the clamping grooves 7 is that the staff can pull up the clamping rods 8 in turn, instead of pulling up multiple clamping rods 8 at the same time, which is convenient for the staff to operate.

[0030] The fixing assembly includes a rotating block 5, which is rotatably connected to the outside of the connecting rod 3. A fixing block 11 is fixedly installed on the rotating block 5. A fixing groove 12 is opened on one side of the clamping rod 8. The fixing block 11 passes through the hole on the limiting block 6 and is inserted into the fixing groove 12.

[0031] By rotating the rotating block 5, the rotating block 5 drives the multiple fixed blocks 11 to rotate. The multiple fixed blocks 11 will pass through the multiple limiting blocks 6 and be inserted into the fixing grooves 12 opened on the multiple clamping rods 8. Due to the downward thrust of the spring 10, the clamping rod 8 will also press down and fix the fixed blocks 11. The clamping rod 8 is fixed by inserting the fixed blocks 11 into the fixing grooves 12, and the clamping rod 8 cannot move up and down.

[0032] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
