[0024] A block 11 is provided at the lower side of the hydraulic cylinder 13, and the block 11 is fixedly connected to the square tube 1. Both ends of the hydraulic cylinder 13 are connected to a hydraulic pump through a hydraulic pipe. A handrail 25 is fixedly installed on one side of the square tube 1. The handrail 25 can facilitate users to use the device.

[0025] A first shear block 9 is fixedly installed on one end of the upper side of the first movable rod 5, and a second shear block 10 is fixedly installed on one end of the lower side of the second movable plate 6. The first shear block 9 and the second shear block 10 can be easily cut off to facilitate the collection and transportation of the construction steel bars.

[0026] One side of the two cylinders 15 is threadedly connected with a first fixing screw 22, and one end of the two first fixing screws 22 can be respectively inserted into the inside of the two circular grooves 16, and one end of the push rod 14 can be inserted into the inside of the two circular grooves 16. The circular grooves 16 are provided to facilitate fixing the push rod 14 and prevent the push rod 14 from being offset during pushing, thereby causing damage to the device.

[0027] Two bolts 17 are movably inserted on the square tube 1, and one end of the two bolts 17 is threadedly connected with a nut 18, and the other end of the two bolts 17 is fixedly connected with a connecting plate 19. A plurality of circular through holes 20 are opened on the telescopic rod 2, and the plurality of circular through holes 20 are arranged in an array. The two bolts 17 are movably inserted through two adjacent circular through holes 20 respectively. The relative positions of the square tube 1 and the telescopic rod 2 can be fixed by the plurality of circular through holes 20 and the two bolts 17.

[0028] like Figure 5 As shown, a second fixing screw 23 is inserted into one side of the second movable round block 4 , and the second movable round block 4 is threadedly connected to the second fixing screw 23 .

[0029] Support frames 24 are fixedly installed on both sides of the telescopic rod 2, and one ends of the two support frames 24 are movably abutted against the two ends of the second movable plate 6 respectively. Two fixing plates 21 are fixedly installed on the upper sides of the two ends of the second movable plate 6 respectively. The two fixing plates 21 at the two ends of the second movable plate 6 are respectively arranged on both sides of the two support frames 24. By setting the support frames 24, the second movable plate 6 of the device can be reinforced to prevent the device from being damaged during operation. By setting the fixing plates 21, the second movable plate 6 of the device can be prevented from being displaced during operation.

[0030] It should be noted that the utility model is a construction steel bar recovery device. When in use, first, the user needs to confirm the size of the cement block adhered to the construction steel bar, then pull the telescopic rod 2 out of the inside of the square tube 1, and wait until the telescopic rod 2 is moved to a suitable position. The user can hold the connecting plate 19, insert the two bolts 17 on one side of the connecting plate 19 through the square tube 1 and two adjacent circular through holes 20 in the plurality of circular through holes 20, and then screw the two nuts 18 onto the two bolts 17 respectively. Then, the user needs to rotate the first movable rod 5 and the second movable plate 6 respectively, so that the end of the first movable rod 5 equipped with the first cone 7 is rotated to the position corresponding to the push rod 14, and then The first movable rod 5 moves toward the position where the push rod 14 is located, so that the push rod 14 is inserted into the corresponding circular groove 16, and then the corresponding first fixing screw 22 is turned so that one end of the first fixing screw 22 abuts against the push rod 14, and then the second movable plate 6 is rotated so that one end of the second movable plate 6 on which the second cone 8 is installed is rotated to the position corresponding to the first cone 7 on the first movable rod 5, and then the second movable plate 6 is moved to the position where the two support frames 24 are located, so that one end of the two support frames 24 is between the two fixing plates 21 at the two ends of the second movable plate 6, and the second fixing screw 23 is turned so that one end of the second fixing screw 23 abuts against one side of the telescopic rod 2;

[0031] Then the user can hold the device with both hands and move the device so that the cement block to be crushed is placed between the first cone 7 and the second cone 8. Then the user needs to control the hydraulic pump so that the hydraulic oil is pumped into the interior of the hydraulic cylinder 13 from one end of the hydraulic cylinder 13, so that the push rod 14 extends out of the hydraulic cylinder 13, and then the push rod 14 drives the cylinder 15, the first movable rod 5 and the first cone 7 to move toward the location of the cement block. When the first cone 7 and the second cone 8 respectively abut against the cement block, as the push rod 14 continuously pushes the first cone 7, cracks begin to appear on the cement block from the contact position between the first cone 7 and the second cone 8, and thus the cement block begins to be crushed. Then the user controls the hydraulic pump to pump the hydraulic oil from the other end of the hydraulic cylinder 13 into the interior of the hydraulic cylinder 13, so that the push rod 14 contracts toward the interior of the hydraulic cylinder 13, and drives the bolt 17 to move toward the location of the hydraulic cylinder 13, and wait until the device is detached from the cement block, and then the next round of cement block crushing operation can be carried out.

[0032] If the user wants to cut off a long building steel bar, the user needs to confirm the thickness of the building steel bar, and then pull the telescopic rod 2 out of the inside of the square tube 1. When the telescopic rod 2 is moved to a suitable position, the user can hold the connecting plate 19, insert the two bolts 17 on one side of the connecting plate 19 through the square tube 1 and two adjacent circular through holes 20 in the plurality of circular through holes 20, and then screw the two nuts 18 onto the two bolts 17 respectively. The user then needs to rotate the first movable rod 5 and the second movable plate 6 respectively, so that the end of the first movable rod 5 on which the first shear block 9 is installed rotates to the position corresponding to the push rod 14, and the first movable rod 5 is moved toward the push rod 1 4 is moved to the position where the push rod 14 is located, so that the push rod 14 is inserted into the corresponding circular groove 16, and then the corresponding first fixing screw 22 is turned so that one end of the first fixing screw 22 abuts against the push rod 14, and then the second movable plate 6 is rotated so that one end of the second movable plate 6 on which the second shear block 10 is installed is rotated to the position corresponding to the first shear block 9 on the first movable rod 5, and then the second movable plate 6 is moved to the position where the two support frames 24 are located, so that one end of the two support frames 24 is located between the two fixing plates 21 at the two ends of the second movable plate 6, and the second fixing screw 23 is turned so that one end of the second fixing screw 23 abuts against one side of the telescopic rod 2;

[0033] Then the user can hold the device with both hands and move the device so that the construction steel bar to be cut is placed between the first shear block 9 and the second shear block 10. Then the user needs to control the hydraulic pump so that the hydraulic oil is pumped into the interior of the hydraulic cylinder 13 from one end of the hydraulic cylinder 13, so that the push rod 14 extends out of the hydraulic cylinder 13, and then the push rod 14 drives the cylinder 15, the first movable rod 5 and the first shear block 9 to move toward the position of the construction steel bar. When the first shear block 9 and the second shear block 10 respectively abut against the construction steel bar, as the push rod 14 continuously pushes the first shear block 9, the construction steel bar will be cut off at the contact position between the first shear block 9 and the second shear block 10. After the construction steel bar is cut off, the user then controls the hydraulic pump to pump the hydraulic oil into the interior of the hydraulic cylinder 13 from the other end of the hydraulic cylinder 13, so that the push rod 14 contracts toward the interior of the hydraulic cylinder 13 and drives the bolt 17 to move to its original position.
