[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0032] like Figures 1 to 5 As shown, this application provides a rebar straightening mechanism, which includes a first fixed plate 1, a straightening drive 3, and a hand handle 5. Two straightening seats 2 are spaced apart along a first direction on the first fixed plate 1. Each straightening seat 2 has a straightening cavity 21 extending through the first direction. The two straightening cavities 21 are coaxially arranged, and part of the cavity wall of the straightening cavity 21 faces the first fixed plate 1. The straightening drive 3 is disposed on the first fixed plate 1, and a top head 4 is disposed at the output end of the straightening drive 3. The straightening drive 3 can drive the top head 4 to move along a second direction so as to abut or move away from the rebar extending through the straightening cavity 21. The hand handle 5 is disposed on the first fixed plate 1, and a control switch 6 is disposed on the hand handle 5. The control switch 6 controls the connection to the straightening drive 3, and the first direction is perpendicular to the second direction.
[0033] The rebar straightening mechanism can be held by the hand handle 5, and the rebar to be straightened can be placed into the straightening cavity 21. Then, the straightening drive 3 is controlled by the control switch 6 on the hand handle 5 to drive the top head 4 to abut against the rebar in the middle part of the two straightening seats 2 for straightening. The device is simple to operate and does not occupy a large space, which can improve the straightening efficiency and improve the space utilization.
[0034] It should be noted here that the first direction refers to Figure 3 In the X direction, the second direction refers to Figure 3 in the Y direction.
[0035] In some embodiments, the control switch 6 is a push-button switch for convenient control operation.
[0036] like Figure 3 and Figure 4 As shown, in some embodiments, the straightening seat 2 uses a hook, which is fixed to the first fixing plate 1. The two hooks face the same direction, and the hook groove of the hook is the straightening cavity 21 mentioned above, with part of the groove wall facing the first fixing plate 1. That is to say, when the reinforcing bar needs to be straightened at a certain point, it is not necessary to insert the end of the reinforcing bar into the straightening cavity 21; it can be directly hooked at the position to be straightened by the hook, thereby further improving the straightening efficiency.
[0037] Since the straightening operation employs two-point support (the contact point between the rebar and the straightening seat 2) and one-point abutment (the contact end between the rebar and the top head 4), the distance between the two support points determines the magnitude of the driving force required by the straightening drive 3. Based on the above principle, the positions of the two straightening seats 2 along the first direction are adjustable, thereby allowing adjustment based on factors such as different rebar sizes and different degrees of curvature. In some embodiments, the straightening seat 2 is provided with a first mounting hole, while the first fixing plate 1 is provided with a plurality of second mounting holes 11 along the first direction. Depending on different requirements, different second mounting holes 11 are selected, and the straightening seat 2 can be locked and fixed to the other by a locking member passing through one of the first mounting holes and the second mounting hole 11. Exemplarily, one of the first mounting hole and the second mounting hole 11 is a screw hole, and the other is a through hole; the locking member can be, but is not limited to, a bolt.
[0038] In some embodiments, to facilitate the installation of the hand handle 5 and ensure its stability, a second fixing plate 7 is provided on the first fixing plate 1. The first fixing plate 1 and the second fixing plate 7 are arranged perpendicularly, and the hand handle 5 is disposed on the second fixing plate 7. In the current embodiment, the opening of the hook faces away from the second fixing plate 7, thereby facilitating the entry of the reinforcing bar into the hook groove. In the current embodiment, the hand handle 5 is rod-shaped.
[0039] In some embodiments, in order to reduce unnecessary interference, the straightening drive 3 and the straightening seat 2 are disposed on opposite sides of the first fixed plate 1. The first fixed plate 1 is provided with a through hole 12, and the output end of the straightening drive 3 passes through the through hole 12, so that the top head 4 and the straightening seat 2 are located on the same side of the first fixed plate 1.
[0040] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the straightening drive 3 is a hydraulic cylinder, which provides sufficient power while miniaturizing the structure. Since the hydraulic cylinder requires a matching power supply component 9 for oil supply, the rebar straightening mechanism also includes a moving carriage 8 for easy movement. The power supply component 9 is mounted on the moving carriage 8, which has a hanging bracket 10. The first fixing plate 1 can be hung on the hanging bracket 10, so that it can be hung on the hanging bracket 10 when not in use, and when needed, it can be moved to the location of the rebar by the moving carriage 8, and the straightening operation can be performed by removing it from the hanging bracket 10 using the handle 5. It is understood that the power supply component 9 is a common component of hydraulic cylinders, and its specific structure will not be described in detail. In other embodiments, the straightening drive 3 can also be a small motor, in which case the power supply component can be a rechargeable battery; or the straightening drive 3 can also be a cylinder, in which case the power supply component 9 can be an air-supplying component, and its specific details will not be described in detail either.
[0041] Furthermore, the mobile vehicle 8 includes a vehicle body 81, which can be enclosed by wall panels. The power supply component 9 is disposed within the enclosed space. One of the side walls may be provided with a door (not shown) that can be opened or closed to control and maintain the power supply component 9. In the current embodiment, the bracket 10 includes at least two spaced support plates 101. One end of the two support plates 101 is fixed to the side wall of the vehicle body 81, and the other end extends away from the vehicle body 81. Thus, when the first fixing plate 1 is placed on the two support plates 101, the straightening drive 3 is located between the gaps formed by the two support plates 101. To avoid shaking during placement, a limiting plate 102 is also provided at the end of the support plate 101 away from the vehicle body 81. The limiting plate 102 is set at an angle with the support plate 101. The limiting plate 102 and the side wall of the vehicle body 81 form a clamping space to restrict the first fixing plate 1 within the clamping space. When needed, the first fixing plate 1 can be lifted by holding the handle 5. To facilitate the connection of the support plate 101 to the vehicle body 81, a connecting plate 103 is provided at the end of the support plate 101 away from the limiting plate 102. The support plate 101 is connected to the side wall of the vehicle body 81 through the connecting plate 103. For example, the support plate 101, the limiting plate 102 and the connecting plate 103 are integrally formed.
[0042] In some embodiments, for ease of movement and locking, a support leg 82 is provided on one side of the bottom wall of the vehicle body 81, and a wheel 83 is provided on the other side. The wheel 83 and the support leg 82 together support the vehicle body 81. When movement is required, the vehicle body 81 can be tilted to lift the support leg 82 off the ground for pushing. For easy pushing, a push handle 84 is also provided on the top of the vehicle body 81.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
