The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIGS. 1 through 6, there is shown a preferred embodiment of the present invention. The bending device 1 of the present invention includes a body 10, a pressing mechanism 20 and two handle portions 30.

The body 10 defines a lateral direction L1 and a circumferential direction L2 around the lateral direction L1, and a first pivoting portion 11 extending from the side to the L1, a guiding surface 12 extending from the circumferential direction to the L2, and a The restraining mechanism 13 of the elongated object 2 is restrained. The pressing mechanism 20 is provided with a second pivoting portion 21 pivotally connected to the first pivoting portion 11. The pressing mechanism 20 can surround the lateral direction L1 at least one. In the embodiment, the at least one release position is, for example, FIG. 5, and the at least one release position is, for example, FIG. 6; in other embodiments, the at least one release position may also be plural. The at least one restricted position may also be plural. The two handle portions 30 are respectively connected to the body 10 and the pressing mechanism 20, and are swingable about the lateral direction L1. The second pivoting portion 21 is directly detachably engaged with the first pivoting portion 11 when the pressing mechanism 20 is in the releasing position. In the embodiment, the second pivoting portion is The second pivoting portion can also be detached from the lateral direction in the lateral direction L1; in the other embodiment, the second pivoting portion is detached from the lateral direction; when the pressing mechanism 20 is in each of the restricted positions, the second pivoting The limiting portion of the portion 21 is connected to the first pivoting portion 11 , whereby the pressing mechanism can be quickly disassembled at each of the released positions, and the elongated object 2 can be smoothly bent at other positions without being easily detached.

In detail, the body 10 is a quarter cylinder, the axial direction of the cylinder is a lateral direction L1, the guiding surface 12 is a circumferential surface of the cylinder, and the pressing mechanism 20 is the first pivoting portion. 11 is a process of center-circle bending the elongated object 2 along the guiding surface 12, and after the bending, the pressing mechanism 20 can be directly detached at each of the releasing positions, and the elongated object 2 is taken out.

One of the first pivoting portion 11 and the second pivoting portion 21 is a shaft bolt, and the other is pivoted to one of the shaft slots. Preferably, the shaft bolt is provided with a maximum radial outer portion. The diameter and an outer diameter are smaller than the narrow diameter of the maximum outer diameter, and the narrow diameter is smaller than the notch 211 of the slot for the card connection, and the maximum radial outer diameter is larger than the notch 211 of the slot for the card. In the embodiment, the first pivoting portion 11 is the axle pin, and the second pivoting portion 21 is the slot. The shaft bolt is detachably disposed on the body 10, thereby replacing the shaft bolt or adjusting the angle of the shaft bolt. In addition, the notch 211 is laterally open, so that the pressing mechanism 20 can be laterally detached or snapped to the body 10 directly at each of the released positions. Preferably, the radial dimension of the slot is larger than the diameter of the slot 211, and the first pivoting portion 11 can pivot smoothly in the slot.

More specifically, when the slot is pivoted relative to the pivot pin to each of the disengaged positions, the narrow diameter corresponds to the notch 211 in parallel, and the pivot pin can be directly laterally disengaged from the slot; When the slot is not pivoted to each of the released positions (for example, when pivoting to each of the restricted positions), each of the axle pins cannot be disengaged from each of the slots.

Preferably, the shaft pin is provided with a radially protruding retaining edge 14 , the outer diameter of the retaining edge 14 is larger than the diameter of the hole; in particular, when the pressing mechanism 20 is engaged with the retaining edge 14 When the body 10 is between the bodies 10, the pressing mechanism 20 cannot be detached from the body 10 toward the lateral direction L1.

The body 10 is provided with at least one first positioning portion 15 , and the pressing mechanism 20 is provided with at least one second positioning portion 22 detachably engaged with the first positioning portion 15; in this embodiment, each of the first One of the positioning portion 15 and each of the second positioning portions 22 is a groove, and the other is a positioning bead that can be detachably engaged with the groove (may also be a spring assembly steel ball). In this embodiment, each of the first positioning portions 15 is the groove, and each of the second positioning portions 22 is the positioning bead.

The number of the at least one first positioning portion 15 is plural, and the plurality of first positioning portions 15 are disposed around the lateral direction L1; the number of the at least second positioning portions 22 is corresponding to the plurality of first positioning portions 15 Preferably, at least two of the plurality of first positioning portions 15 are oppositely disposed.

The body 10 includes a detachable sheet 16 that is provided with the restraining opening 13. By replacing the detachable piece 16 , the elongated object can be applied to different lengths and cross-sectional shapes. In the embodiment, the elongated object is a round rod or a round tube, and the restraining opening 13 is a U-shaped hole.

Preferably, the body 10 is provided with an indicator 40 corresponding to the initial position of the pressing mechanism 20, such as the position of the pressing mechanism 20 before the bending. The indicator 40 can be an engraved, printed, embossed structure, etc., without restricting its structural form; thus, the user can visually judge whether the pressing mechanism 20 is properly mounted on the body 10, for example, When used against a wall. In detail, for example, when the pressing mechanism 20 completely covers the indicator 40, it is a proper position.

In summary, the pressing mechanism of the present invention can be quickly attached and detached to the body at each of the releasing positions, and the main body cannot be detached from the main body to provide stable operation and easy to remove the elongated object, so that the elongated object is not easy to be used. The damage remains intact.
