The movable seat 34 drives the upper support sleeve 2 to move synchronously after moving, so that the center of gravity of the round steel needs to be found when the round steel is used, and the movable seat 34 can be moved to the lower part of the center of gravity of the round steel to support.
The use principle of the invention is as follows: when the clamping structure 4 of the present invention is used, the approximate position of the moving structure 3 is determined according to the length of the round steel, if necessary, the rotating part can be operated to rotate the lead screw 32, the lead screw 32 drives the moving seat 34 to move when rotating, the moving seat 34 drives the round steel to be processed to pass through the circular hole of the support sleeve 2 of the support structure, and then the end of the round steel is continuously moved, at this time, the corresponding tightening rod 421 needs to be operated, and after the length of the tightening rod 421 is changed, the end of the transmission rod 422 far away from the tightening rod 421 is driven to move, so as to act on the execution component 44. The installation shell 441 of the executing assembly 44 is limited by the first limiting plate 431 and the second limiting plate 432 to move in the horizontal plane, the adjusting degree of the tightening rod 421 is determined according to the end of the round steel, the round steel passes through the clamping hole 4411 after the position of the clamping hole 4411 is determined, the connecting plate 442 needs to be moved downwards by rotating the adjusting rod 445, the connecting plate 442 drives the two first wedge blocks 443 to move downwards, the two second wedge blocks 444 overcome the resistance of the first spring 446, therefore, the two second wedge blocks approach to each other to control the round steel in the middle of the clamping hole 4411, the adjusting rod 445 continues to rotate until the connecting plate 442 presses on the upper portion of the round steel, and clamping is completed.
The above is only a preferred embodiment of the present invention, and it should be noted that several modifications and improvements made by those skilled in the art without departing from the technical solution should also be considered as falling within the scope of the claims.
