[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Example 1

[0037] Reference Figure 1The embodiment of the present application discloses a steel bar bending tool, which includes a fixed cylinder 1 and a handle 2 provided on the fixed cylinder 1. In the present embodiment, the connection between the fixed cylinder 1 and the handle 2 includes but is not limited to being connected by welding to form an integral structure. The fixed cylinder 1 is a cylindrical cylinder, and the inner cavity diameter of the fixed cylinder 1 includes but is not limited to 30 mm. The handle 2 is a cylindrical structure, and the diameter of the handle 2 includes but is not limited to 20 mm. The fixed cylinder 1 and the handle 2 are made of high-strength and wear-resistant metal materials, and the metal materials include but are not limited to alloy steel and stainless steel materials, so as to ensure that the steel bar bending tool has sufficient strength and durability during use;

[0038] The fixed tube 1 is provided with an opening 11. In the present embodiment, the diameter of the opening 11 includes but is not limited to 28 mm, and the opening 11 is arranged along the barrel direction of the fixed tube 1; the steel bar includes a main bar and a stirrup, and the main bar is inserted into the inner cavity of the fixed tube 1 through the opening 11; a bayonet 12 is provided on the fixed tube 1. In the present embodiment, the diameter of the bayonet 12 includes but is not limited to 30 mm, and the bayonet 12 is arranged at the middle position in the barrel direction of the fixed tube 1, and the stirrup passes through the bayonet 12 and is inserted into the bayonet 12; the handle 2 is rotated with the main bar as a fulcrum, and the fixed tube 1 and the stirrup are driven to rotate, so as to realize the bending of the stirrup;

[0039] The inner walls of the fixing tube 1 and the bayonet 12 are both designed as smooth surfaces. The design of the smooth inner surface can effectively reduce the wear and scratches on the surface of the steel bar, protect the surface quality of the main bar and the stirrup, and extend the service life of the steel bar; and the design of the smooth inner surface can reduce the friction resistance of the main bar and the stirrup when the fixing tube 1 and the bayonet 12 are in contact, making the rotation smoother, reducing the force required for operation, and reducing the labor intensity of the user;

[0040] During operation, the main reinforcement is inserted into the inner cavity of the fixed tube 1 through the opening 11 of the fixed tube 1, and the stirrups are passed through the bayonet 12 and are stuck in the bayonet 12, and then the handle 2 is rotated with the main reinforcement as the fulcrum, and the handle 2 is pressed down using the lever principle. The handle 2 will drive the fixed tube 1 to rotate together with the stirrups, and during the rotation, the stirrups will bend with the rotation of the fixed tube 1 to achieve the bending processing of the stirrups. In this process, the main reinforcement is used as a fulcrum to provide stable support, avoiding shaking and deformation during the bending process, and the fixed tube 1 and the bayonet 12 are designed so that the stirrups are fixed in position during the bending process, thereby ensuring the accuracy of the bending angle.

[0041] The fixed tube 1 is provided with an angle mark 3, which is used to indicate the rotation angle of the stirrups. In the present embodiment, the rotation angle scale of the angle mark 3 is arranged along the circumference of the fixed tube 1, and the angle mark 3 includes but is not limited to being arranged on one side of the fixed tube 1 body close to the end; when using the steel bar bending tool, the handle 2 is rotated with the main reinforcement as the fulcrum, and the handle 2 is pressed down by using the lever principle, and the handle 2 will drive the fixed tube 1 and the stirrups to rotate. During this process, the operator observes the rotation angle scale on the angle mark 3 to bend the steel bar to the required angle, which is a working cycle; the angle mark 3 can help the operator grasp the rotation angle of the stirrups, realize the control of the bending angle, ensure the processing of steel bar components that meet the requirements, and can also reduce the technical requirements for the operator, reduce the difficulty of operation, and improve the convenience of operation.

[0042] In this embodiment, the sizes of the fixing tube 1 , the handle 2 , the bayonet 12 on the fixing tube 1 , and the opening 11 are customized according to the specific conditions on site.

[0043] The implementation principle of Example 1 is: the steel bar bending tool of the present application can complete the bending process of steel bars through simple operation, and has the advantages of high efficiency, convenience, accuracy, stability, good durability and convenient operation during the working process;

[0044] During operation, the main reinforcement is inserted into the inner cavity of the fixed cylinder 1 through the opening 11 of the fixed cylinder 1, and the stirrup is passed through the bayonet 12 and is clamped in the bayonet 12. The handle 2 is rotated with the main reinforcement as the fulcrum, and the handle 2 is pressed down by the lever principle. The handle 2 drives the fixed cylinder 1 and the stirrup to rotate together. During the rotation, the stirrup will bend with the rotation of the fixed cylinder 1. In this process, the operator observes the rotation angle scale line on the angle mark 3 to bend the steel bar to the required angle. This is a working cycle, and the bending process of the stirrup is realized.

[0045] The steel bar bending tool of the present application utilizes the lever principle and uses the main reinforcement as a fulcrum to provide stable support, thereby avoiding shaking and deformation during the bending process. The fixed tube 1 and the bayonet 12 design ensure that the stirrups are fixed in position during the bending process, thereby ensuring the accuracy of the bending angle. The angle mark 3 can help the operator grasp the rotation angle of the stirrups, achieve control of the bending angle, and ensure that a steel bar component that meets the requirements is processed.

[0046] Example 2

[0047] Reference Figure 2 The difference between this embodiment and embodiment 1 is that the fixed cylinder 1 and the handle 2 are detachably connected; thus, the steel bar bending tool can be applied to steel bars of different diameters by replacing the fixed cylinder 1, thereby enhancing the flexibility of the tool;

[0048] A connecting sleeve 4 is provided on the fixing cylinder 1. In the present embodiment, the connecting sleeve 4 and the fixing cylinder 1 are made of, but not limited to, one-piece molding or welding connection. A threaded portion is provided on the handle 2. In the present embodiment, a threaded groove corresponding to the threaded portion is provided in the connecting sleeve 4. The threaded portion is inserted into the connecting sleeve 4 and threadedly connected with the connecting sleeve 4. The design of a threaded sleeve and a threaded portion is adopted between the fixing cylinder 1 and the handle 2 to realize a detachable connection. Moreover, since the threaded connection has good firmness and stability, the connecting sleeve 4 on the fixing cylinder 1 and the threaded portion on the handle 2 can be more firmly fixed together through the threaded connection during use, thereby avoiding the risk of loosening or breakage, making the steel bar bending tool more stable and reliable during operation, and improving work efficiency and safety.

[0049] The implementation principle of Example 2 is as follows: the steel bar bending tool of this embodiment is designed with a detachable connection between the fixed cylinder 1 and the handle 2, that is, the steel bar bending tool can be suitable for steel bars of different diameters by only replacing the fixed cylinder 1, thereby enhancing the flexibility of the tool; and by replacing the fixed cylinder 1 instead of purchasing multiple steel bar bending tools of different sizes, costs can be saved; the detachable connection can also facilitate the later maintenance and replacement of the fixed cylinder 1 or the handle 2, thereby improving the operational convenience and making the steel bar bending tool more practical.

[0050] Example 3

[0051] Reference Figure 3 The difference between this embodiment and embodiment 1 is that an adjusting member 5 is provided on the fixing tube 1, and one side of the stirrup passing through the bayonet 12 is clamped and limited by the adjusting member 5;

[0052] The adjusting member 5 includes two fixing blocks 51 arranged on the fixing cylinder 1. The two fixing blocks 51 are arranged opposite to each other along the bayonet 12. An adjusting screw 52 is arranged on the fixing block 51. The adjusting screw 52 passes through the fixing block 51. An adjusting plate 53 is arranged on the side of the adjusting screw 52 close to the bayonet 12. The two adjusting plates 53 clamp the stirrup together. A nut 54 is threadedly connected on the side of the adjusting screw 52 away from the adjusting plate 53. The nut 54 abuts against the fixing block 51.

[0053] The thickness of the adjustment plate 53 is smaller than the wall thickness of the fixed tube 1; thus, the adjustment plate 53 has sufficient space and flexibility when clamping the stirrups, and the clamping effect will not be affected by space restrictions. In addition, this design can also reduce the friction and resistance caused to the stirrups during the clamping process, thereby increasing the applicability and practicality of the adjustment member 5.

[0054] The adjusting plate 53 is arranged to fit the outer wall of the fixing tube 1 , thereby reducing the swing and shaking of the adjusting member 5 during operation and improving the stability of the clamping operation of the adjusting member 5 .

[0055] The implementation principle of Example 3 is as follows: when the steel bar bending tool of this embodiment is working, the stirrups are passed through one side of the bayonet 12, and then the adjusting screws 52 on the two fixed blocks 51 are adjusted so that the stirrups are clamped by the two adjusting plates 53, and then the nut 54 is screwed on. The nut 54 is threadedly connected to the adjusting screw 52 and abuts against the fixed block 51, ensuring the stability and reliability of the adjusting member 5 to complete the adjustment and clamping work of the adjusting member 5; the stirrups are fixed and limited by clamping the stirrups together with the two adjusting plates 53, thereby improving the accuracy and stability of the stirrups during bending, thereby improving the processing quality.

[0056] Example 4

[0057] Reference Figure 4 The difference between this embodiment and the first embodiment is that the handle 2 is provided with an anti-slip portion 6. In this embodiment, the anti-slip portion 6 is an anti-slip cover. The material of the anti-slip cover includes but is not limited to rubber material and silicone material. The design of the anti-slip cover adjusts the hardness and surface texture according to the use requirements to provide a good anti-slip effect.

[0058] In this embodiment, two anti-slip covers are provided on the handle 2 for the operator to grasp the handle 2 with both hands. The design distance between the two anti-slip covers conforms to the ergonomic design to ensure the comfort and operation stability when the operator holds the handle 2 with both hands.

[0059] The implementation principle of Example 4 is: the steel bar bending tool of this embodiment can increase the holding stability and comfort of the handle 2 when the tool is operated through the design of the anti-slip portion 6, and can increase the friction between the user's hand and the handle 2, preventing the handle 2 from sliding due to hand sweating or other reasons during operation, thereby ensuring safety and stability during operation.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
