[0024] See also Figure 1-5 As shown, the thread rolling device of the rope head rod is used to support and fix the loading platform 2 on the bottom of the rope head base 1. A placement groove for placing the rope head base 1 is provided on the loading platform 2, so the rope head base 1 is directly placed on the placement groove, and then the position of the rope head base 1 is limited by the limiting column 5, that is, when in use, the limiting column 5 is rotated to the limiting groove 9 of the rope head base 1, and the limiting column 5 is moved downward to achieve the limiting column 5. Inserted into the inside of the limiting groove 9, the position of the rope head base 1 is further limited, and then the moving component 6 is used to drive the rope head base 1 to move, that is, the moving component 6 is used to contact the limiting groove 9 away from the end of the rope head rod body 10. The rope head base 1 is driven to move in the placement groove, so that the placement position of the rope head base 1 is accurately adjusted. Then, the fixing part installation base 8 is moved downward to clamp the clamping assembly on the upper part of the rope head base 1, thereby clamping and fixing the rope head base 1. In this process, the initial position of the rope head base 1 can also be corrected to ensure that the threaded area 11 at the end of the rope head rod body 10 is in a more accurate position during the thread rolling operation, thereby ensuring the accuracy of the thread rolling. At the same time, the rope head base 1 is limited by the limiting column 5 and the placement groove to avoid the position movement of the rope head rod body 10 during the thread rolling process, thereby further ensuring the accuracy of the rope head rod body 10 during the thread rolling operation.

[0025] That is, a bottom motor 3 is fixed on the feeding platform 2, wherein a mounting base plate 4 is installed at the output end of the bottom motor 3, wherein the mounting base plate 4 is fixedly installed at the output end of the clamping telescopic rod 7, a fixed part mounting base 8 is fixed at the fixed end of the clamping telescopic rod 7, a moving component 6 is fixed at the side of the fixed part mounting base 8, and a limiting column 5 and a clamping component are arranged at the output end of the moving component 6, that is, when in use, the bottom motor 3 is used to control the rotation of the mounting base plate 4, thereby controlling the position of the limiting column 5, and under the action of the clamping telescopic rod 7, the height adjustment of the fixed part mounting base 8 and the feeding platform 2 is controlled, thereby being able to control the distance between the clamping component and the feeding platform 2, so as to facilitate the clamping and fixing of the rope head base 1.

[0027] A pushing assembly is provided on the movable column 66, and the moving column 66 is controlled to move by the pushing assembly. A downward pressure limit frame 63 is fixed at the bottom of the support frame 61, and a clamping assembly is provided on the downward pressure limit frame 63. The clamping assembly includes two groups of limit plates 64, wherein the limit plates 64 are located on both sides of the limit column 5, that is, when the support frame 61 moves downward under the action of the clamping telescopic rod 7, the limit plates 64 move toward the rope head base 1, so that the rope head base 1 is pressed downward and limited by the limit plates 64.

[0028] As a further embodiment of the present application, the pushing component includes an adjusting motor 62, wherein the adjusting motor 62 is fixedly mounted on the downward pressure limit frame 63, a connecting rotating rod 68 is fixed at the output end of the adjusting motor 62, a sleeve rotating rod 67 is rotatably mounted at the end of the connecting rotating rod 68 away from the adjusting motor 62, wherein the sleeve rotating rod 67 is rotatably mounted on the moving column 66 at one end away from the connecting rotating rod 68. When in use, the starting of the adjusting motor 62 is used to drive the rotation of the connecting rotating rod 68, thereby driving the sleeve rotating rod 67 to move adaptively, and then driving the moving column 66 to move laterally under the action of the limiting slide groove 65, thereby controlling the position of the limiting column 5.

[0029] When the utility model is in use, the present invention first places the rope head base 1 in the placement groove, and then uses the bottom motor 3 to control the rotation of the mounting base plate 4, thereby controlling the position of the limit column 5, and under the action of the clamping telescopic rod 7, controls the height adjustment of the fixed part mounting base 8 and the loading platform 2, so as to be able to control the distance between the clamping assembly and the loading platform 2. At this time, the limit column 5 initially enters the interior of the limit groove 9, and uses the start of the adjustment motor 62 to drive the rotation of the connecting rotating rod 68, thereby driving the sleeve rotating rod 67 to move adaptively, and then drives the movable column 66 to move laterally under the action of the limiting slide groove 65, controls the position of the limit column 5, that is, the limit groove 9 is moved to the end of the placement groove under the action of the limit column 5, and at this time continues to start the clamping telescopic rod 7, so that the limit column 5 enters the interior of the placement base, and at the same time the limit plate 64 moves toward the rope head base 1, so that the rope head base 1 is pressed down and limited by the limit plate 64.
