[0032] A locking device is arranged between the movable pushing rod 11 and the U-shaped slot 12, which can connect the U-shaped slot 12 with the movable pushing rod 11. The locking device includes a first locking block 16 and a second locking block 20. The front and rear side walls of the movable pushing rod 11 are provided with clamping devices that can limit the U-shaped slot 12 to make the connection more stable. The clamping device includes a clamping plate 23.

[0033] It is worth noting that the working platform 10, the reducer 29, the movable push rod 11 and the U-shaped slot 12 have all been disclosed in the steel bar bending machine (201620523177.4), and will not be described in detail here.

[0034] During specific use, the locking device can connect the movable push rod 11 with the U-shaped slot 12, so that the staff can easily replace the U-shaped slots 12 of different specifications. The clamping device can limit the U-shaped slot 12 and make the connection between the movable push rod 11 and the U-shaped slot 12 more stable.

[0035] To sum up, by setting up the locking device and the clamping device, the locking device can connect the movable pushing rod 11 with the U-shaped slot 12, so that the staff can conveniently replace the U-shaped slots 12 of different specifications, and the clamping device can limit the U-shaped slot 12, and can also make the connection between the movable pushing rod 11 and the U-shaped slot 12 more stable, which can save a lot of working time for the staff, and has the characteristics of easy use and simple structure.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, a first fixed block 13 is fixedly installed on the upper and lower side walls of the right end of the movable pushing rod 11, a second limiting groove 19 is opened on the right side wall of the two first fixed blocks 13, and a first limiting groove 18 is opened on the side wall away from each other of the two first fixed blocks 13.

[0037] There are two first locking blocks 16, and the two first locking blocks 16 are respectively fixedly installed in the cavity of the first limiting groove 18. The first locking block 16 passes through the first limiting groove 18. A first return spring 17 is fixedly installed on the two side walls of the first locking block 16 close to the first fixed block 13, and the other ends of the two first return springs 17 are respectively fixedly connected to the side wall of the first fixed block 13 away from the movable push rod 11.

[0038] There are two second engaging blocks 20, and the two second engaging blocks 20 are respectively fixedly mounted on the upper and lower side walls of the U-shaped slot 12. A engaging groove 21 is provided on the side wall away from each other of the two second engaging blocks 20. The ends of the first engaging block 16 and the engaging groove 21 that are close to each other are both arc-shaped. The second engaging block 20 is inserted into the cavity of the second limiting slot 19, and the first engaging block 16 can also be inserted into the cavity of the engaging groove 21.

[0039] During specific use, when installing the U-shaped slots 12 of different specifications, the staff can align the two second locking blocks 20 with the cavity of the second limiting groove 19 and then insert them. The arcuate surfaces of the first locking block 16 and the second locking block 20 can move the first locking block 16 upward when the second locking block 20 contacts the first locking block 16. When the first locking block 16 corresponds to the position of the locking groove 21, the first locking block 16 can be inserted into the cavity of the locking groove 21 through the force of the first return spring 17. It is worth mentioning that: the first return spring 17 has the force to move the first locking block 16 closer to the first fixed block 13, and the first limiting groove 18 can limit the first locking block 16, so that the U-shaped slot 12 can be connected to the movable push rod 11.

[0040] To sum up, by setting the second locking block 20, the locking groove 21, the first locking block 16, the first return spring 17, the first limiting groove 18, the first fixing block 13, the second limiting groove 19, the U-shaped locking groove 12 and the movable pushing rod 11, the first locking block 16 can be inserted into the cavity of the locking groove 21, so as to connect the movable pushing rod 11 with the U-shaped locking groove 12, which has the advantages of easy locking and quick installation.

[0041] like Figure 2 , Figure 5 and Figure 6 As shown, a second fixing block 15 is fixedly installed on the front and rear side walls of the movable pushing rod 11, and a third fixing block 22 is fixedly installed on the upper and lower side walls of the second fixing block 15. The side walls of the two third fixing blocks 22 that are away from each other are both hollow.

[0042] A moving block 26 is movably installed in the cavity of the two third fixed blocks 22, and a second return spring 27 is fixedly installed on the side wall of the two moving blocks 26 close to each other. The end of the second return spring 27 away from the moving block 26 is fixedly connected to the inner wall of the cavity of the third fixed block 22.

[0043] The side walls of the two moving blocks 26 that are away from each other are both hollowed out, a rotating plate 28 is rotatably installed in the cavity of the moving block 26, and a pressing plate 24 is fixedly installed on the side walls of the two rotating plates 28 that are away from each other.

[0044] A limiting rod 25 is provided at the right end of the pressing plate 24, and the limiting rod 25 passes through and is movably connected to the pressing plate 24. One end of the pressing plate 24 close to the movable pushing rod 11 is rotatably connected to the movable pushing rod 11. A clamping plate 23 is fixedly installed on the right end wall surface of the two pressing plates 24 away from each other. The two clamping plates 23 can be located at the upper and lower side wall positions of the U-shaped slot 12.

[0045] When the U-shaped slot 12 is connected to the movable pushing rod 11, the staff needs to press the two corresponding pressing plates 24 to move closer to each other, and the pressing plates 24 can be rotated according to the limiting rod 25. The rotation of the pressing plates 24 can drive the clamping plates 23 to rotate. After the movable pushing rod 11 is connected to the U-shaped slot 12, the pressing plates 24 can be released so that the two clamping plates 23 clamp and limit the U-shaped slot 12. The rotating plate 28 can drive the moving block 26 to move up and down during the rotation of the pressing plate 24. The second return spring 27 has a force that pushes the two moving blocks 26 away from the third fixed block 22. In this way, when the staff releases the pressing plate 24, the pressing plate 24 can be automatically reset, and the clamping force is applied to the U-shaped slot 12 by the clamping plate 23. The third fixed block 22 can limit the moving block 26, and the second fixed block 15 can limit the third fixed block 22.

[0046] To sum up, by setting the clamping plate 23, the limiting rod 25, the pressing plate 24, the second fixed block 15, the third fixed block 22, the moving block 26, the second return spring 27 and the rotating plate 28, the second return spring 27 and the clamping plate 23 can apply a clamping force to the U-shaped slot 12, and the U-shaped slot 12 can be limited and fixed, which can make the U-shaped slot 12 more stable and have a double insurance effect.
