[0025] Specifically, the cooperation between the hand wheel 10, the worm 8 and the worm gear 9 makes the adjustment of the length of the connecting rod 2 self-locking, that is, the worm 8 can be rotated by rotating the hand wheel 10, and then the worm gear 9 is rotated, and the two-way threaded rod 5 is rotated by the rotation of the worm gear 9, so that the internal thread block 4 can drive the connecting rod 2 to move outward, and the worm 8 cannot be driven to rotate by the worm gear 9, which can improve the safety of the power rod. The limit block 6 is used to limit the connecting rod 2. When the internal thread block 4 slides to fit with the end of the limit block 6 close to the two-way threaded rod 5, the connecting rod 2 moves to the maximum limit, that is, the maximum length that the thrust rod can be adjusted. The limit circle block 22 can provide limiting and support for the two-way threaded rod 5.
[0026] Reference Figure 3 and Figure 4 , the outer wall of the main rod 1 is provided with a rectangular groove 21, and the inner wall of the main rod 1 is provided with an inner groove 11;
[0027] Specifically, the rectangular groove 21 is used to provide a sliding space for the handle 16 , and the inner groove 11 is used to provide a sliding space for the moving block 14 .
[0028] Reference Figure 1 、 Figure 3 and Figure 4 The inner wall of the main rod 1 is slidably connected with a sliding column 12, the top of the sliding column 12 is fixedly connected to a limited block 2 15, the bottom end of the sliding column 12 is fixedly connected to a moving block 14, the outer wall of the sliding column 12 is slidably connected with a spring 13, one end of the spring 13 is fixedly connected to the upper surface of the moving block 14, and the other end of the spring 13 is fixedly connected to the inner wall of the inner groove 11; the outer wall of the moving block 14 is slidably connected to the inner wall of the inner groove 11, and the upper surface of the moving block 14 is fixedly connected with a handle 16; the outer wall of the handle 16 is provided with a through groove 17, and the outer wall of the handle 16 is slidably connected to the inner wall of the rectangular groove 21; the outer wall of the main rod 1 is fixedly connected to a rectangular frame 18; the outer wall of the sliding column 12 is fixedly connected to a tension band 20, the outer wall of the tension band 20 is slidably connected to the inner wall of the rectangular frame 18, and the outer wall of the tension band 20 is fixedly connected to a limited block 3 19;
[0029] Specifically, in the process of lifting the thrust rod upward, the handle 16 will drive the moving block 14 to move upward and slide on the inner wall of the inner groove 11, so that the moving block 14 drives the sliding column 12 to slide inside the main rod 1 and move upward, driving the limit block 2 15 to move upward, and at the same time prompting the spring 13 to slide on the outer wall of the sliding column 12 and contract under force, so that the sliding column 12 pulls the tension band 20 to slide on the inner wall of the rectangular frame 18, driving the limit block 3 19 to move to the limit, and then part of the lifting force can be dispersed to the tension band 20 and the rectangular frame 18.
[0030] Working principle: when it is necessary to adjust the use length of the thrust rod, it is only necessary to turn the hand wheel 10. When the hand wheel 10 rotates, it will drive the worm 8 to rotate on the inner wall of the main rod 1 and drive the worm gear 9 to rotate. When the worm gear 9 rotates, it will drive the bidirectional threaded rod 5 to rotate. When the bidirectional threaded rod 5 rotates, it will rotate on the inner wall of the internal thread block 4 and cause the internal thread block 4 to move outward, thereby causing the internal thread block 4 to drive the connecting rod 2 to slide on the inner wall of the main rod 1 and move outward, thereby causing the connecting rod 2 to drive the joint 3 and the protrusion 7 to move outward, thereby achieving the effect of adjusting the use length, and then the length can be adjusted according to the actual installation environment, thereby improving the versatility of the thrust rod in different equipment. When the thrust rod is carried, Hold the handle 16 through the through slot 17, and then lift the thrust rod upward. During the upward lifting process, the handle 16 will drive the moving block 14 to move upward, and then the moving block 14 will drive the sliding column 12 to slide upward inside the main rod 1 and drive the limit block 2 15 to move upward, while causing the spring 13 to be forced to contract. When the sliding column 12 moves upward, it will pull the tension belt 20 to slide on the inner wall of the rectangular frame 18, and then the tension belt 20 will drive the limit block 3 19 to move to the limit, and then part of the lifting force can be dispersed to the tension belt 20 and the rectangular frame 18, so that the thrust rod can be subjected to more uniform force during the lifting process, reducing tilting and shaking, helping to maintain the stability of the thrust rod and reducing the risk of accidents.
