[0026] As shown, Figure 11 And Figure 12As shown, the auxiliary mechanism 4 includes an auxiliary bin 41; the auxiliary bin 41 is rotatably connected with an auxiliary lead screw 42; the auxiliary lead screw 42 is threadedly connected with an auxiliary block 43; the auxiliary block 43 is fixedly connected with a connecting block 44; the connecting block 44 is fixedly connected with a hinged shaft 45; the hinged shaft 45 is sleeved with a hinged plate 46; the end of the hinged plate 46 away from the hinged shaft 45 is sleeved with the hinged column 38; the hinged plate 46 is fixedly connected with a fixed box 461; the bottom of the fixed box 461 is slidably provided with a top rod 462; the end of the fixed arm 37 away from the fixed column 361 is fixedly connected with a fixed block 371; the fixed block 371 is provided with an expansion slot 372; the expansion slot 372 is fixedly connected with a fixed spring 373; the end of the fixed spring 373 away from the expansion slot 372 is fixedly connected with a clamping block 374; the clamping block 374 is movably clamped with the fixed box 461; the two sides of the adjusting plate 21 are fixedly connected with a tooth 211; the top of the auxiliary bin 41 is rotatably connected with a gear one 47 and a gear two 48; the side wall of the auxiliary bin 41 is rotatably connected with a gear three 49; the output end of the gear three 49 is fixedly connected with the input end of the auxiliary lead screw 42; the gear two 48 is meshingly connected with the tooth 211; the gear one 47 is meshingly connected with the gear three 49; the auxiliary bin 41 is provided with a plurality of groups; When working, since the clamping column 35 needs to be fixed after clamping the reinforcing steel bars to prevent the reinforcing steel bars from loosening, the clamping block 374 on the fixed arm 37 is clamped with the fixed box 461 after clamping is completed. When the adjusting plate 21 moves, the auxiliary lead screw 42 in the auxiliary bin 41 is driven to rotate through the tooth 211 on both sides. When rotating, the auxiliary block 43 and the connecting block 44 move. When the connecting block 44 moves, the hinged plate 46 sleeved with the connecting block 44 and the hinged column 38 moves. The purpose is to limit the movement of the adjusting plate 21 through the hinged plate 46 to avoid the adjusting plate 21 from shaking. The movement of the hinged plate 46 is completed before the reinforcing steel bars are fixed. After the hinged plate 46 moves, the fixed arm 37 moves to the fixed box 461. When moving, the clamping block 374 in the fixed block 371 contacts the fixed box 461 and is pressed into the fixed block 371 through the fixed box 461. After the fixed block 371 is perpendicular to the fixed box 461, the fixed spring 373 in the fixed block 371 presses the clamping block 374 into the fixed box 461 to achieve clamping. After the reinforcing steel bars are clamped by the hoop, they need to be taken out of the sleeve.

When pressing, the top rod 462 lifts the clamping block 374. Then the clamping block 374 is removed from the fixed box 461. Through the setting of the auxiliary bin 41, the limiting effect of the adjusting plate 21 can be achieved when the adjusting plate 21 moves to avoid the adjusting plate 21 from deviating to cause the construction size to be inconsistent. Through the setting of the fixed box 461, the fixed arm 37 can be fixed to avoid loosening after the reinforcing steel bars are fixed.

When the adjustment plate 21 moves, the reading can be made through the pointer 1 222.

When the rotating fixed arm 37 drives the clamping column 35 to fix the steel bar, the vertical plate 33 will pull the connecting spring 331. After the clamping block 374 is clamped with the fixing box 461, the connecting spring 331 is in a pulled state. When the clamping block 374 and the fixing box 461 are cancelled, the connecting spring 331 rebounds, which will drive the clamping column 35 away from the steel bar, thereby releasing the fixation of the steel bar.

[0029] like Figure 2 As shown, the side wall of the mobile bin 11 is rotatably connected to a turntable 14; the output end of the turntable 14 is fixedly connected to the input end of the bidirectional screw rod 12; During operation, the bidirectional screw rod 12 is driven to rotate by the turntable 14, thereby realizing the movement of the adjustment plate 21.

[0030] like Figure 1 As shown, the mobile bin 11 is located in the middle of the bottom plate 1; the auxiliary bins 41 are located on both sides of the mobile bin 11; During operation, when the adjustment plate 21 moves, the auxiliary bins 41 on both sides will be driven to work, wherein the driving gear 231, the driven gear 241, the gear 1 47 and the gear 3 49 are bevel gears.

[0031] The working principle of the present application is: after adjusting the size and position of the fixing base plate 31 in the fixing mechanism 3, the reinforcing steel bars are placed into the sleeve 36 on the fixing base plate 31, and then the fixing arm 37 is actuated to rotate the sleeve 36 and the connecting plate 34 on the fixing base plate 31, and in the process of rotation, the movement of the clamping column 35 is driven by the connection of the pin shaft one 351 and the connecting groove 362, and the center of the pin shaft one 351 is not consistent with the center of the clamping column 35, so that the clamping column 35 is moved to the center of the sleeve 36 while the pin shaft one 351 is driven, and in the process of movement, the pin shaft two 353 slides in the moving groove 3211, and the pin shaft two 353 is limited by the moving groove 3211, so that the connecting plate 352 does not deviate in the process of movement, and then the reinforcing steel bars are placed into the sleeve 36, and then the fixing arm 37 is rotated to rotate the sleeve 36, and the three groups of clamping columns 35 below are moved to the center of the sleeve 36 at the same time, so that the reinforcing steel bars are fixed by the clamping columns 35, and then the fixing arm 37 is fixed by the auxiliary mechanism 4 after being fixed, so as to avoid the movement of the clamping column 35 and the loosening of the reinforcing steel bars during operation, and the reinforcing steel bars can be quickly fixed by the fixing mechanism 3, and the installation size of the reinforcing steel bars can be quickly adjusted by cooperating with the adjustment mechanism 2, which is convenient for operation.
