Detailed Implementation
[0037] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0038] like Figure 1 and Figure 2 As shown in the figure, an embodiment of this utility model discloses a stirrup bending tool, comprising: a main handle 1, a guide rod 2, a hook structure 4, and a stirrup stop 3; the main handle 1 is used to operate the hook structure 4 and the stirrup stop 3 via the guide rod 2. The guide rod 2 is a straight rod structure; the guide rod 2 is a cylindrical rod, which facilitates the sliding of the hook structure 4 and the stirrup stop 3 on the guide rod 2. One end of the guide rod 2 is fixedly mounted on the main handle 1, preferably by welding, for a firm and reliable installation. There are two guide rods 2; the two guide rods 2 are arranged parallel to each other at intervals; the guide rod 2 has multiple pin holes; the multiple pin holes are distributed at intervals along the guide rod 2. The pin holes on the two guide rods 2 are coaxially distributed in a one-to-one correspondence.
[0039] The hook structure 4 includes: a support structure 4-1, a hook 4-2, a hook 4-3, and a limiting pin 4-4. Two guide holes are parallel to each other at both ends of the support structure 4-1. These two guide holes are fitted onto two guide rods 2, allowing them to slide along the guide rods 2. The hook 4-2 is fixedly positioned on one side of the support structure 4-1. The hook 4-2 and the support structure 4-1 are constructed into a "U"-shaped hook structure. There are two hooks 4-2. The two hooks 4-2 are distributed parallel to each other at intervals. The opening directions of the two hooks 4-2 are the same. During operation, the two hooks 4-2 can simultaneously hook the main reinforcing bar. The unbent reinforcing bar rests in the groove 3-3 of the stirrup stop 3. Then, by rotating the stirrup stop 3 with the handle, the bending tool can only rotate around the main reinforcing bar due to the limitation of the hook 4-2. The bending operation of the stirrup is achieved through the stirrup stop 3. After the stirrup is bent, the tool is rotated in the opposite direction to disengage from the stirrup.
[0040] Hook 4-3 is fixedly mounted on the other side of support structure 4-1; hook 4-3 and support structure 4-1 are constructed into a "U"-shaped hook structure; there are two hooks 4-3; the two hooks 4-2 are distributed parallel to each other; the opening directions of the two hooks 4-3 are opposite; during operation, the two hooks 4-3 can simultaneously hook the rebar to be bent, and then by rotating the handle, one hook 4-3 pulls back while the other pushes forward, thus achieving the bending operation of the stirrup. Preferably, hooks 4-2 and 4-3 have the same structure, which makes the bending of the rebar easier to standardize and simplifies processing.
[0041] The support structure 4-1 has a limiting hole; the limiting pin 4-4 passes through the limiting hole and the pin hole, restricting the hook structure 4 to the predetermined position of the guide rod 2. As needed, the limiting hole can be aligned with different pin holes to set the hook structure 4 at a suitable position on the guide rod 2.
[0042] The stirrup stop 3 includes: a second support structure 3-1 and a second limiting pin 3-2; two guide holes 2 are provided parallel to each other at both ends of the second support structure 3-1; the two guide holes 2 are fitted onto two guide rods 2 and can slide along the guide rods 2; the middle part of the second support structure 3-1 is a plate-like structure; a sliding groove 3-3 is provided on the plate-like structure; the sliding groove 3-3 faces the hook structure 4 to cooperate with the hook structure 4 to bend the stirrup. Preferably, the sliding groove 3-3 is a "U"-shaped groove with an arc-shaped bottom to match the reinforcing bar. There can be multiple sliding grooves 3-3; multiple sliding grooves 3-3 are distributed in parallel at intervals; the size of multiple sliding grooves 3-3 can be set as needed to improve its adaptability.
[0043] The support structure 3-1 has a limiting hole 2; the limiting pin 3-2 passes through the limiting hole 2 and the pin hole, restricting the stirrup stop 3 to the predetermined position 2 of the guide rod 2; as needed, the limiting hole 2 can be aligned with different pin holes, and the stirrup stop 3 can be set at a suitable position on the guide rod 2. The distance between the stirrup stop 3 and the hook structure 4 can be adjusted by setting it at different pin holes to accommodate the bending requirements of steel bars with different spacings. Operators can adjust it on-site as needed.
[0044] One embodiment of this utility model provides a stirrup bending tool that can bend stirrups in various states, improving the tool's applicability and ease of operation.
[0045] An embodiment of this utility model provides a stirrup bending tool, which further includes: an auxiliary handle 5; the auxiliary handle 5 includes: a support structure 5-1, a sleeve 5-2, and a limiting pin 5-3; two guide holes 3 are provided parallel to each other at both ends of the support structure 5-1; the two guide holes 3 are sleeved on two guide rods 2; the support structure 5-1 has a limiting hole 3; the limiting pin 3-3 passes through the limiting hole 3 and the pin hole, restricting the auxiliary handle 5 to a predetermined position 3 of the guide rod 2. The auxiliary handle 5 allows the operator to apply force with both hands simultaneously to bend the rebar in certain situations. Further preferably, the outer wall of the sleeve 5-2 is provided with an anti-slip structure to facilitate the operator's grip and reduce slippage.
