If the terms "first" or "second" are described, they are only used for descriptive purposes and cannot be understood to indicate or imply relative importance.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figures 1 to 4 A steel bar auxiliary bending tool includes: an installation rod 100, the installation rod 100 is slidably connected to a push block 110 along its length direction, the push block 110 is rotatably connected to a connecting rod 120, one end of the connecting rod 120 is rotatably connected to a bending rod 130, the bending rod 130 is rotatably connected to the installation rod 100, one end of the bending rod 130 is provided with a cross plate 131, the cross plate 131 is provided with a positioning piece 140, the positioning piece 140 is used to clamp the radial steel bar 210 of the steel cage 200, when the push block 110 reciprocates along the installation rod 100, the bending rod 130 rotates, so that the cross plate 131 rotates with the positioning piece 140 as the fulcrum.

[0028] When the steel bar auxiliary bending tool of the above structure is used, the positioning member 140 is clamped to the radial steel bars 210 of the steel bar cage 200, so that the cross plate 131 can abut against the plurality of radial steel bars 210, and then people hold the installation rod 100 with one hand and push the push block 110 to move toward one end of the cross plate 131 with the other hand, so that the connecting rod 120 drives the bending rod 130 to rotate, and then the cross plate 131 rotates with the positioning member 140 as a fulcrum, and finally drives the plurality of radial steel bars 210 to bend to the axial steel bars 220. Among them, the linear movement of the push block 110 is converted into the rotation of the bending rod 130, which is conducive to reducing the range of forward leaning of people's bodies, so that only the hand movement can be performed and the range of body movement can be reduced, and the plurality of radial steel bars 210 can be bent, which is conducive to reducing the amount of manual labor, thereby improving the efficiency of steel bar bending.

[0029] It is understandable that in order to prevent the push block 110 from rotating during the movement, thereby preventing the push block 110 from being offset and affecting the movement of the mechanism, the push block 110 can be connected to the mounting rod 100 through a key. In addition, the mounting rod 100 can also have a rectangular portion, and the push block 110 is provided with a mounting hole that matches the shape of the rectangular portion, so that the rectangular portion is inserted into the mounting hole to limit the movement and rotation of the push block 110. In some embodiments, one end of the connecting rod 120 can be slidably arranged along the length direction of the bending rod 130, the push block 110 is fixedly connected to the connecting rod 120, and the connecting rod 120 is tiltedly arranged on the mounting rod 100, so that the push block 110 also pushes the bending rod 130 to rotate during the movement.

[0030] See also Figures 1 to 4 Furthermore, the transverse plate 131 is provided with two arc-shaped rods 132, and the arc-shaped rods 132 are used to be clamped to the axial reinforcement 220 of the reinforcement cage 200, and the positioning member 140 is located between the two arc-shaped rods 132. Specifically, during the rotation of the transverse plate 131, the two arc-shaped rods 132 form arc surface contact with the axial reinforcement 220, so that the two arc-shaped rods 132 can play the role of guiding the two ends of the rotation of the transverse plate 131, which is conducive to improving the effect of the transverse plate 131 bending the radial reinforcement 210.

[0031] See also Figures 1 to 4 Furthermore, the transverse plate 131, the arc rod 132 and the positioning member 140 are an integrated structure. Specifically, the transverse plate 131, the arc rod 132 and the positioning member 140 can be fixed as a whole by welding, thereby improving the connection strength between the transverse plate 131, the arc rod 132 and the positioning member 140, which is conducive to ensuring that the transverse plate 131 can bend the radial steel bar 210.

[0032] See also Figures 1 to 4 Furthermore, the positioning member 140 includes two insertion rods 141 arranged parallel to each other, one end of the insertion rod 141 is connected to the cross plate 131, and a gap for accommodating the radial reinforcement 210 is formed between the two insertion rods 141. Specifically, when in use, one of the radial reinforcements 210 of the reinforcement cage 200 is inserted between the two insertion rods 141, so that the cross plate 131 can rotate with the two insertion rods 141 as positioning points, which is conducive to regulating the rotation of the cross plate 131.

[0033] See also Figures 1 to 4 Furthermore, a stopper 150 is provided at one end of the mounting rod 100 away from the bending rod 130, and an elastic member 160 is connected between the stopper 150 and the push block 110. Specifically, during the rotation of the bending rod 130, the push block 110 drives one end of the elastic member 160 to move, so that the elastic member 160 is in a stretched state. After the transverse plate 131 bends the radial steel bars 210, people release the push block 110, and the elastic member 160 recovers its deformation to drive the push block 110 to move toward the end away from the transverse plate 131, thereby facilitating the subsequent restoration of the bending rod 130 to the initial position, which is conducive to improving people's use experience.

[0034] See also Figures 1 to 4 Furthermore, the stopper 150 is a nut threadedly connected to the mounting rod 100, and the elastic member 160 is a spring sleeved on the mounting rod 100, so that the elastic force of the spring is used to drive the push block 110 to reset. Two nuts can be provided, and a gasket is provided between the two nuts to increase the contact area with the spring, which is conducive to better extension or retraction of the spring.

[0035] See also Figures 1 to 3Furthermore, the outer wall of the push block 110 is provided with a side extension rod 111 for assisting pushing and pulling, so that people can push the push block 110 to move by holding the side extension rod 111, which is conducive to improving people's use experience.

[0036] See also Figures 1 to 3 Further, a sleeve 170 is provided at one end of the mounting rod 100 away from the bending rod 130, and a sponge layer is provided on the outer peripheral wall of the sleeve 170, so that the sleeve 170 can be held by a human hand, which is beneficial to people's use experience. In some embodiments, the sleeve 170 can be provided with grooves for people's fingers, which is beneficial to better grip.

[0037] See also Figures 1 to 3 Furthermore, the mounting rod 100 and the bending rod 130, the push block 110 and the connecting rod 120, and the connecting rod 120 and the bending rod 130 are connected by a pivot, so that the push block 110, the connecting rod 120 and the bending rod 130 form a connecting rod 120 mechanism, which has a simple structure and compact movement, and is conducive to driving the bending rod 130 to rotate. In order to facilitate the connection between the connecting rod 120 and the push block 110, the push block 110 is provided with a mounting groove 112, and the two opposite side walls of the mounting groove 112 are provided with a first through hole, one end of the connecting rod 120 is built into the mounting groove 112, and one end of the connecting rod 120 is provided with a second through hole, so that the pivot passes through the first through hole and the second through hole, and finally one end of the connecting rod 120 is connected to the push block 110.
