A bending mechanism is provided on the other end of the connecting rod 20, which means that when in use, the first connecting rod 9 and the second connecting rod 20 act on an anchor rod 2, and the two bending mechanisms are distributed up and down and are mirror-imaged. The bending mechanism includes a C-shaped tube 10, and the notch portion 11 of the C-shaped tube 10 is arranged outward, and a baffle 12 is arranged in the notch portion 11 of the C-shaped tube 10, and end plates 14 are arranged at both ends of the baffle 12. Grooves 13 for placing the end plates 14 are provided on the C-shaped tube 10 at both ends of the notch portion 11, and limiting through holes 15 are provided on the ends of the grooves 13 and the end plates 14, and limiting rods 16 are provided inside the limiting through holes 15, and a limiting plate 17 is provided on one end of the limiting rod 16, and the end of the limiting rod 16 is fixedly connected to the limiting plate 17, and the limiting plate 17 arranged at the end of the first connecting rod 9 is arranged upward, and the C-shaped tube 10 is rotatably connected to the first connecting rod 9.

[0028] The working principle of the above technical solution is:

[0029] When in use, firstly, according to the number of anchor rods 2 at the anchoring position 1, the same number of first connecting rods 9 are installed on the ring nut 4, and then the second connecting rod 20 is also adaptively installed. After the installation is completed, the baffle 12 on the C-shaped tube 10 is removed, and the two C-shaped tubes 10 distributed up and down are sleeved on the anchor rod 2, and then the baffle 12 is locked and installed on the notch part 11 through the limit rod 16. At this time, the anchor rod 2 is located in the two C-shaped tubes 10, and then the drive motor 26 is started to rotate the drive motor 26. The rotation of the ring nut 4 is restricted by the anchor rod 2, so the ring nut 4 will move downward, and when moving downward, the first connecting rod 9 will squeeze the anchor rod 2 to rotate outward. At the same time, since the C-shaped tube 10 arranged on the end of the second connecting rod 20 will not move, the rotation of the anchor rod 2 below the first connecting rod 9 will be restricted, that is, the anchor rod 2 will be bent outward with the position above the C-shaped tube 10 of the second connecting rod 20 as the bending point, and then bend outward under the action of the first connecting rod 9. After the bending is completed, it is only necessary to disassemble the baffle 12 to remove the C-shaped tube 10. Therefore, the device can realize the simultaneous bending operation of multiple anchor rods 2, and the heights of the multiple anchor rods 2 after bending are consistent, and there will be no unevenness.

[0030] It should be noted that the baffle 12 is provided to block the anchor rod 2 to prevent the anchor rod 2 from coming out of the notch 11 during bending, and the C-tube 10 is provided to be sleeved on the anchor rod 2. At the same time, the mirror-image arrangement of the upper and lower bending mechanisms is intended to set the limit plate 17 provided on the lower C-tube 10 downward to prevent it from being blocked by the bent anchor rod 2, which would cause the limit rod 16 to be unable to be pulled out. The rotating seat 18 adopts a rotating bearing arrangement to prevent the rotation of the screw rod 3 from driving the sleeve 19 to rotate, that is, the movements of the two do not interfere with each other. When used simultaneously, the housing of the drive motor 26 can be prevented from rotating by the operator holding the housing of the drive motor 26 by hand, or a fixed frame can be provided. No further elaboration is given here.

[0031] In one practicable manner, the C-shaped tube 10 disposed on the end of the first connecting rod 9 and the C-shaped tube 10 disposed on the end of the second connecting rod 20 are rotatably connected at one end thereof, and the rotation direction of the rotatable connection is consistent with the bending direction of the anchor rod 2 .

[0032] The rotational connection can be achieved through a rotating shaft and a connecting block, which will not be elaborated on here. The advantage of the rotational connection is that the C-tube 10 on the lower second connecting rod 20 can pull and limit the C-tube 10 set on the upper first connecting rod 9, thereby preventing it from sliding on the anchor rod 2 under the action of the first connecting rod 9, resulting in a poor bending effect.

[0033] In one practicable manner, a first slip ring 6 is provided on the lower surface of the annular nut 4, and a plurality of first fixing plates 5, preferably four first fixing plates 5, are provided on the first slip ring 6. The first fixing plates 5 fix the first slip ring 6 to the annular nut 4. A plurality of sliders 7 are provided on the first slip ring 6. The slider 7 is sleeved on the first slip ring 6. The sleeved setting here means that a through hole is provided on the slider 7, and the through hole is sleeved on the first slip ring 6, that is, the slider 7 can rotate and move on the first slip ring 6. The slip rings at both ends of the slider 7 are provided with a first limiting clamp 8, and the clamp can limit the end position of the slider 7 on the first slip ring 6 by clamping on the first interchangeable, and one end of the first connecting rod 9 is rotatably connected to the slider 7.

[0034] The setting of the above-mentioned scheme can adjust the position of the slider 7 on the first slip ring 6, and then adjust the position of the first connecting rod 9 and the C-shaped tube 10 arranged thereon, and then match the situation where multiple anchor rods 2 are arranged in a non-circular manner. It can be understood that the spacing and angles between adjacent anchor rods 2 are different, and this setting method can set the distribution of such anchor rods 2.

[0035] In one practicable manner, a second slip ring 22 is provided on the outer side surface of the upper end of the sleeve 19, and a plurality of second fixing blocks are provided on the sleeve 19. The second fixing blocks fix the second slip ring 22 on the sleeve 19. One end of the second connecting rod 20 is sleeved on the second slip ring 22, and second limiting clamps 24 are provided on both sides of the end of the second connecting rod 20. The second limiting clamps 24 are used to limit the end position of the second connecting rod 20 on the second slip ring 22.

[0036] In one practicable manner, a third slip ring 23 is provided on the outer side surface of the lower end of the sleeve 19, and a third fixing block is provided on the outer side surface of the sleeve 19, and the third fixing block fixes the third slip ring 23 to the sleeve 19, and a plurality of third connecting rods 21 are provided on the third slip ring 23, one end of the third connecting rod 21 is sleeved on the third slip ring 23, and the other end of the third connecting rod 21 is rotatably connected to the second connecting rod 20, and a third limiting hoop 25 is provided on one end of the third connecting rod 21 sleeved on the third slip ring 23, and the third limiting hoop 25 is used to limit the end position of the third connecting rod 21 on the third slip ring 23.

[0037] This arrangement of the second link 20 and the third link 21 can adapt to the angle and position changes of the first link 9, and thus match the situation of the unevenly distributed anchor rod 2. At the same time, the arrangement of the third link 21 can limit the angle deflection of the second link 20, thereby ensuring that the position of the bending part of the anchor rod 2 is more accurately controllable, thereby avoiding the lower C-shaped tube 10 being pulled by the upper C-shaped tube 10, causing its position to change, resulting in the problem of a change in the bending position.

[0038] In one practicable manner, the second link 20 and the second link 20 are both retractable to adapt to the different bending heights of the anchor rod 2. The retractable setting can facilitate adjustment of the position installed on the anchor rod 2, and the height of the bending position of the anchor rod 2 can be accurately adjusted. It should be noted that the retractable method and structure are existing technologies and will not be elaborated on here.

[0039] In one feasible manner, a plurality of locking bolts 27 are provided in the middle portion of the baffle plate 12 provided on the second connecting rod 20. The locking bolts 27 are threadedly connected to the baffle plate 12 to tighten the anchor rod 2 in the C-shaped tube 10. The setting of the locking bolts 27 fixes the C-shaped tube 10 provided at the lower portion to the anchor rod 2. The advantage of this is that the position of the lower C-shaped tube 10 can be further controlled, thereby further improving the accuracy of the bending portion of the anchor rod 2. At the same time, it can also prevent the C-shaped tube 10 from sliding on the anchor rod 2, resulting in a poor bending effect.

[0040] In an practicable manner, the inner diameter of the C-shaped tube 10 is larger than the diameter of the anchor rod 2, and the width of the notch portion 11 of the C-shaped tube 10 is larger than the diameter of the anchor rod 2. This facilitates adapting to various bending operations of the anchor rod 2 without notification.

[0041] In one feasible manner, the locking bolt 27 is provided with a plurality of protruding teeth at the abutment position of the anchor rod 2, which can be understood as a rack-type setting, and the spacing of the protruding teeth matches the spacing of the threads on the anchor rod 2. The advantage of this is that the protruding teeth will be tightly clamped between the adjacent threads of the anchor rod 2, thereby preventing the locking bolt 27 from sliding on the anchor rod 2, causing the bending position to change.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
