[0023] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a clamping hand guide rod, including an outer rod body 1, an electric push rod 2 is fixedly connected inside the outer rod body 1, the output end of the electric push rod 2 is fixedly connected with a middle rod body 3, a fixed rod 4 is fixedly connected inside the middle rod body 3, a cam 5 is rotatably connected to the outer wall of the fixed rod 4, a transmission belt 6 is arranged on the outer wall of the cam 5, a first fixing block 7 is fixedly connected to one side of the outer wall of the transmission belt 6, the outer wall of the first fixing block 7 is fixedly connected to the inner wall of the middle rod body 3, a second fixing block 8 is fixedly connected to the other side of the outer wall of the transmission belt 6, the outer wall of the second fixing block 8 is fixedly connected with an inner rod body 9, the outer wall of the inner rod body 9 is slidably connected inside the outer rod body 1, one end of the inner rod body 9 is fixedly connected with a support 10, a positioning assembly is arranged on the outer wall of the support 10, and the positioning assembly is used for positioning the installation of the guide rod;

[0024] Specifically, first, the output end of the electric push rod 2 drives the middle rod body 3 to slide inside the outer rod body 1, ensuring the precise displacement of the middle rod body 3. As the middle rod body 3 slides, the transmission belt 6 is effectively driven. One side of the transmission belt 6 is firmly fixed to the inner wall of the outer rod body 1 by the first fixing block 7. The rotation of the transmission belt 6 not only drives its own movement but also further promotes the movement of the second fixing block 8. As the second fixing block 8 moves, the inner rod body 9 slides inside the inner wall of the middle rod body 3. Finally, through the movement of the inner rod body 9, the support 10 also moves accordingly, thereby driving the movement of the mounting seat 11 and realizing the adjustment of the length of the guide rod.

[0025] Refer to Figure 1 and Figure 3 , the positioning component includes the mounting seat 11. The outer wall of the mounting seat 11 is fixedly connected to the outer wall of the support 10, the outer wall of the mounting seat 11 is fixedly connected to the outer wall of the outer rod body 1, the outer wall of the mounting seat 11 is fixedly connected with a positioning sleeve 18, the inside of the mounting seat 11 is rotatably connected with a rotating rod 19, the outer wall of the rotating rod 19 is fixedly connected with a worm 12, the worm 12 is rotatably connected inside the mounting seat 11, the inside of the mounting seat 11 is rotatably connected with a worm gear 13, the worm 12 meshes with the worm gear 13, the inside of the worm gear 13 is fixedly connected with a screw 14, the screw 14 is rotatably connected inside the mounting seat 11 and the positioning sleeve 18, the outer wall of the screw 14 is threadedly connected with a sliding sleeve 15, the outer wall of the sliding sleeve 15 slides inside the mounting seat 11, the inside of the sliding sleeve 15 is rotatably connected with a connecting rod 16, one end of the connecting rod 16 is rotatably connected with a clamping block 17, the connecting rod 16 slides inside the mounting seat 11 and the positioning sleeve 18, and the outer wall of the clamping block 17 slides inside the positioning sleeve 18;

[0026] Specifically, first, drive the rotating rod 19 to drive the worm 12 to rotate inside the mounting seat 11. Due to the meshing effect of the worm gear 13 and the worm 12, the screw 14 can rotate with the rotation of the worm 12, thereby driving the sliding sleeve 15 to slide on the outer wall of the screw 14. Through the transmission of the connecting rod 16, finally, the clamping block 17 slides inside the positioning sleeve 18 to the outer wall of the clamp, so as to firmly limit the guide rod to the outer wall of the clamp and realize the guiding function of the clamp. When disassembling the guide rod, just rotate the rotating rod 19 in the reverse direction, and the clamping block 17 can slide back from the outer wall of the clamp to the inside of the positioning sleeve 18, so that the guide rod can be easily removed from the clamp, which not only simplifies the disassembly and assembly process of the guide rod but also improves the work efficiency, making the use of the entire mechanical structure more convenient and efficient.

[0027] Working principle: When the clamping hand guide rod needs to be used, first, the output end of the electric push rod 2 drives the middle rod body 3 to slide inside the outer rod body 1, driving the transmission belt 6 to move. One side of the transmission belt 6 is firmly fixed to the inner wall of the outer rod body 1 by the first fixing block 7, ensuring that the transmission belt 6 can rotate stably between the two cam wheels 5. As the transmission belt 6 rotates, it further drives the movement of the second fixing block 8. The movement of the second fixing block 8 drives the inner rod body 9 to slide inside the middle rod body 3. Finally, through the movement of the inner rod body 9, the support 10 also moves accordingly, driving the movement of the mounting seat 11, achieving effective adjustment of the guide rod and reaching the expected effect;

[0028] In addition, place the mounting seats 11 at both ends of the guide rod at the specified positions of the clamping hand, and then drive the rotating rod 19 to drive the worm 12 to rotate inside the mounting seat 11. Due to the meshing of the worm gear 13 and the worm 12, the worm gear 13 drives the screw 14 to rotate as the worm 12 rotates. Furthermore, the sliding sleeve 15 slides on the outer wall of the screw 14. Then, through the movement of the sliding sleeve 15, one end of the connecting rod 16 is driven to move. Thus, the other end of the connecting rod 16 drives the block 17 to slide inside the positioning sleeve 18. When the block 17 slides to the outer wall of the clamping hand, the guide rod can be restricted to the outer wall of the clamping hand to guide the clamping hand. When disassembling, only need to rotate the rotating rod 19 in the reverse direction, achieving the effect of disassembling and assembling the guide rod.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
