The setting of the scale line and the reading arrow ensures that the staff can control the position of the steel bar through the scale.

[0032] Reference Figure 2 - Figure 4 A plurality of control grooves 93 are provided on the control ring 92, and a plurality of long rods 91 are slidably arranged inside the plurality of control grooves 93 respectively. A pull ring 1 94 is fixedly connected to one end of each fixing ring 77 close to the screw rod 74, and a pull ring 2 95 is fixedly connected to one end of each positioning ring 73 close to the screw rod 74. A groove matching the long rod 91 is provided on the inner walls of the pull ring 1 94 and the pull ring 2 95. The plurality of long rods 91 respectively penetrate the inner walls of the plurality of pull rings 1 94 and the plurality of pull rings 2 95. A motor 10 is fixedly connected to the right side of the fixing plate 8, and the output shaft of the motor 10 penetrates the inner wall of the fixing plate 8 and is fixedly connected to the right end of the screw rod 74.

[0033] Preferably, a plurality of push rods 53 are provided, and the plurality of push rods respectively correspond to the positions of the plurality of positioning rings 73 .

[0034] Working principle: In the initial position, the positioning plate 2 75 is close to one side of the positioning plate 1 71. The staff first puts the steel bars into the feed trough 3, and through the left inner wall of the positioning shell 2, ensure that the left end of the steel bars contacts the inner wall of the positioning shell 2 when they are put in, thereby ensuring that the steel bars are in a flush position.

[0035] After the steel bars enter the feed trough 3, they move toward the inside of the positioning groove 4 under the action of gravity, and are arranged in a ring shape under the control of the shape of the positioning groove 4. When the arrangement is completed, the staff starts the cylinder 51, so that the cylinder 51 pushes the control plate 52, and drives multiple push rods 53 to move to the right through the control plate 52, so that the push rods 53 push the steel bars, causing the steel bars to move to the right.

[0036] When the steel bar moves to the right under the force, the steel bar first contacts the left end of the positioning ring 73. Since the left end of the positioning ring 73 is set as a hollow cone, and the end with a larger inner diameter of the hollow cone is located on the left, even if the right end of the steel bar tends to move downward due to gravity, it can move toward the position inside the positioning ring 73 under the control of the hollow cone at the left end of the positioning ring 73, and finally move to the right end to enter the fixed ring 77.

[0037] When the right end of the steel bar enters the interior of the fixing ring 77, the staff starts the motor 10, so that the motor 10 drives the screw 74 to rotate, thereby causing the positioning plate 2 75 to move to the right. At this time, the cylinder 51 and the motor 10 work simultaneously, driving the steel bar to move to the right along with the fixing ring 77.

[0038] When the positioning plate 2 75 moves to contact with the right end of the moving block 783, since the pressure plate 785 is subjected to the leftward elastic force of the elastic member 786, and the gas pressure inside the air pressure chamber 781 is less than the elastic force of the elastic member 786, the moving block 783 first moves to the left relative to the positioning plate 2 75 under the action of the pressure plate 785. Therefore, the air pressure inside the air pressure chamber 781 increases at this time, so the airbag 782 expands and squeezes the outside of the steel bar. Therefore, the right end of the steel bar is fixed, and the steel bar can continue to move to the right under the joint action of the fixing ring 77 and the positioning plate 2 75.

[0039] When the right end of the steel bar moves to a suitable position, the staff rotates the control ring 92 as needed, so that the multiple long rods 91 slide in the multiple control grooves 93 respectively, and then adjusts the distance from the multiple long rods 91 to the center point of the control ring 92. When the position of the long rod 91 changes, the long rod 91 drives the fixing ring 77 and the positioning ring 73 to move through the pull ring 1 94 and the pull ring 2 95 respectively, thereby changing the position of the steel bar. When the position of the steel bar is adjusted, the staff can weld the longitudinal steel bars to achieve the connection effect.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
