[0057] A seventh bevel gear 488 is keyed to the auxiliary rod of the second telescopic shaft 487 in the second cavity 461 , and an eighth bevel gear 489 meshing with the seventh bevel gear 488 is keyed to the adjustment shaft 47 in the second cavity 461 .

[0058] Start the sixth motor 481, and the output shaft of the sixth motor 481 drives the first screw rod 482 to rotate. Because the first threaded hole on the second connecting block 42 is threadedly connected to the first screw rod 482, when the first screw rod 482 rotates, the second connecting block 42 will be displaced relative to the first connecting block 41, and the second connecting block 42 drives the third connecting block 43 to move, and the secondary shaft on the first telescopic shaft 483 will move relative to the main shaft. The secondary shaft on the first telescopic shaft 483 drives the fifth bevel gear 484 to rotate, the fifth bevel gear 484 drives the sixth bevel gear 486 to rotate, and the sixth bevel gear 486 drives the second screw rod 485 to rotate; because the second threaded hole on the fifth connecting block 45 is threadedly connected with the second screw rod 485, when the second screw rod 485 rotates, the fifth connecting block 45 will move relative to the third connecting block 43, and the secondary shaft on the second telescopic shaft 487 drives the seventh bevel gear 488 to rotate, the seventh bevel gear 488 drives the eighth bevel gear 489 to rotate, the eighth bevel gear 489 drives the adjusting shaft 47 to rotate, and the adjusting shaft 47 drives the adjusting rod 49 to rotate.

[0059] refer to Figure 2 and Figure 8 The end of the adjustment rod 49 away from the adjustment shaft 47 is fixedly connected to the second fixed block 34, and the second clamping block 35 is slidably connected to the second fixed block 34. The second adjustment assembly 38 is arranged on the second fixed block 34, and the second adjustment assembly 38 has the same structure as the third adjustment assembly 53. The fifth motor 531 in the second adjustment assembly 38 is arranged on the second fixed block 34, and the sixth rack 533 in the second adjustment assembly 38 is arranged on the second clamping block 35.

[0060] The second clamping block 35 is located above the first clamping block 32 , and the second clamping block 35 and the first clamping block 32 form a clamping space for clamping the mother tube 11 .

[0061] The implementation principle of a clamping device in an embodiment of the present application is: first select a suitable number of second support blocks 21, then clamp the first reinforcement block 71 with the first reinforcement groove 212 on the second support block 21, clamp the second reinforcement block 72 with the second reinforcement groove, and clamp the reinforcement block 68 with the reinforcement groove.

[0062] Then, the first motor 231 is started, so that the lifting block 22 drives the first adjusting block 51 to move, the first adjusting block 51 drives the second adjusting block 52 to drive the first fixing block 31 to move, and the first fixing block 31 drives the first clamping block 32 to move, so that the first clamping block 32 moves to a suitable position. Then, the mother tube 11 is placed on the first clamping block 32.

[0063] Then the fourth motor 361 is started to rotate the second clamping block 35 to the top of the first clamping block 32; then the hydraulic cylinder 368 is started, the first support block 33 on the piston rod of the hydraulic cylinder 368 drives the first connection block 41 to move, the second connection block 42 on the first connection block 41 drives the third connection block 43 to move, the fourth connection block 44 on the third connection block 43 drives the fifth connection block 45 to move, the sixth connection block 46 on the fifth connection block 45 drives the adjustment shaft 47 to move, the adjustment rod 49 on the adjustment shaft 47 drives the second fixed block 34, the second clamping block 35 on the second fixed block 34 moves toward the direction close to the first clamping block 32 and presses against the mother tube 11 located on the first clamping block 32. Then the mother tube 11 is drawn to form the drawn tube 12.

[0064] When the drawing equipment is at different positions in the length direction of the mother tube 11, the fourth motor 361 and the hydraulic cylinder 368 on the partial lifting block 22 can be started first to make the second clamping block 35 no longer conflict with the mother tube 11; then the first motor 231 can be started to make the first clamping block 32 on the lifting block 22 no longer conflict with the mother tube 11; and then the second motor 691 can be started to move the second support block 21 corresponding to this part of the lifting block 22 to avoid the position where the mother tube 11 needs to be pulled.

[0065] When the angle difference between adjacent drawing positions on the mother tube 11 is not very large, and when there is only one or very few drawing devices for drawing the same mother tube 11, after drawing one drawing tube 12, the fifth motor 531 in the first adjusting assembly 37 and the fifth motor 531 in the second adjusting assembly 38 are started, so that the first clamping block 32 and the second clamping block 35 drive the mother tube 11 to rotate.

[0066] When the mother tube 11 is located on the lifting block 22, the side of the mother tube 11 away from the second support block 21 is the upper end, and when the pulling position is located at the upper end of the mother tube 11, the fifth motor 531 in the first adjustment component 37, the fifth motor 531 in the second adjustment component 38, the fifth motor 531 in the third adjustment component 53, and the sixth motor 481 can be started. Under the action of the fifth motor 531 in the first adjustment component 37 and the fifth motor 531 in the second adjustment component 38, the position of the first clamping block 32 can be adjusted; under the action of the fifth motor 531 in the third adjustment component 53 and the sixth motor 481, the position of the second clamping block 35 can be adjusted. Thus, the first clamping block 32 and the second clamping block 35 can clamp the side walls on both sides of the mother tube 11.

[0067] Moreover, when the mother tube 11 is located on the first clamping block 32, the second clamping block 35 cannot contact the upper end of the mother tube 11. The sixth motor 481 can be started first, so that the position of the sixth connecting block 46 not only changes relative to the position of the lifting block 22, but also the adjusting shaft 47 drives the adjusting rod 49 to rotate, and the adjusting rod 49 drives the position of the second fixed block 34 to change. In this way, when the hydraulic cylinder 368 drives the first supporting block 33 to move toward the lifting block 22, the second clamping block 35 can press against the side wall of the mother tube 11.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
