[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0025] Example:

[0026] A reinforcing bar bending device, reference Figure 1, comprising a handle 1, a sleeve 2 and an angle measuring assembly 3; the sleeve 2 is fixedly arranged at one end of the handle 1, and is used to be sleeved on the to-be-bent portion 5.1 of the reinforcing bar 5; the angle measuring assembly 3 is arranged at the other end of the handle 1, and is used to measure the bending angle of the reinforcing bar 5. Through the angle measuring assembly, the device can measure the bending angle of the reinforcing bar while the reinforcing bar is bent, so as to ensure that the reinforcing bar is bent in place and improve the construction quality.

[0027] The central axis of the sleeve 2 is parallel to the central axis of the handle 1, and is used to keep the handle 1 parallel to the portion 5.1 to be bent of the reinforcing bar 5. The angle measuring assembly 3 includes a protractor 3.1 and a support plate 3.2; one end of the support plate 3.2 is connected to the end of the handle 1 by a hinge, and is used to keep the support plate 3.2 and the handle 1 closed, or open at an angle; the protractor 3.1 is fixedly arranged on the handle 1, and its center point coincides with the position of the hinge, and is used to measure the opening angle of the handle 1 and the support plate 3.2.

[0028] The central axis of the sleeve is parallel to the handle, which can ensure that when the sleeve is placed on the reinforcing bar, the handle and the part to be bent of the reinforcing bar remain parallel. At the same time, the backing plate is stopped on the non-bending part of the reinforcing bar, so that the backing plate and the non-bending part remain parallel, so that the angle between the handle and the backing plate is the angle between the part to be bent and the bending part of the reinforcing bar. By measuring the angle, the reinforcing bar is guaranteed to be bent in place, thereby improving the construction quality.

[0029] A reset spring 3.3 is also provided between the handle 1 and the backing plate 3.2. The reset spring facilitates closing the angle measuring assembly when it is not in use, or resets it after use, so as to avoid damaging the device and taking up space to affect the operation of workers.

[0030] The backing plate 3.2 is an arc-shaped backing plate 3.2, which is used to wrap the handle 1 when closed, or to wrap the non-bending part 5.2 of the tie rod 5 when opened. The arc-shaped backing plate makes it more convenient and stable when the backing plate is closed or resting on the tie rod.

[0031] The protractor 3.1 is a transparent protractor, which is convenient for measuring angles and makes the measurement more accurate.

[0032] The handle 1 is also provided with a handle 4. The handle allows the operator to perform bending operations at multiple angles and is also convenient to carry.

[0033] The handle 1 is a threaded steel bar. The sleeve 2 is a nut. The threaded steel bar has a diameter of 25mm or 28mm and a length of 30cm to 50cm. The nut size is M10, M12 or M14. The protractor has a protractor diameter of 10cm to 15cm. The handle is made of steel bars with a diameter of 6mm to 12mm bent into a curved shape, wherein the threaded steel bar is welded to the nut, and the steel bar handle is welded to the threaded steel bar. Through the above arrangement, the material is easy to obtain and the production is simple, which can greatly reduce the construction period and reduce the loss of manpower and material resources.

[0034] When the reinforcing bar bending device of this embodiment is used, refer to Figure 2 (a), first put the sleeve on the part of the reinforcing bar to be bent in the opposite direction, and close the arc-shaped support plate on the handle. The user holds the far end of the handle and performs the first large-scale bend. Then, the direction is changed and the support plate is opened to perform a second small-scale bend on the reinforcing bar. Figure 2 (b) and further observe the angle between the backrest and the handle using a protractor, such as Figure 2 As shown in (c), in this embodiment, the bending angle needs to be greater than 135°, and finally the reinforcement is obtained after being bent at a certain angle.

[0035] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
