[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the portable wire and cable bending machine of this embodiment includes a mounting plate 1, a force-bearing rod 2 and a handle 3. An arc-shaped hole 12 is opened at one end of the mounting plate 1; a force-bearing rod 2 is arranged at the center position of the arc-shaped hole 12, and the bottom of the force-bearing rod 2 is fixed to the mounting plate 1; the handle 3 is arranged on the back side of the mounting plate 1, one end of the handle 3 is fixed to one end of a connecting bolt 31, and the other end of the connecting bolt 31 is fixed to a sliding nut 32 after passing through the arc-shaped hole 12, and the sliding nut 32 is slidably connected to the mounting plate 1 at the periphery of the arc-shaped hole 12.

[0025] The utility model uses a mounting plate 1 with an arc-shaped hole 12 at one end, a force-bearing rod 2 and a handle 3 to bend wires and cables. The overall volume of the device is small and easy to carry.

[0026] Furthermore, a strip-shaped hole 11 is opened in the middle of the mounting plate 1 , and a plurality of movable bolts 13 are arranged inside the strip-shaped hole 11 .

[0027] The movable bolt 13 can provide support for the wires and cables, making it easier for workers to perform bending operations.

[0028] Furthermore, a scale is marked on the surface of the mounting plate 1 above the strip-shaped hole 11 .

[0029] The scale can measure while bending the wires and cables to reduce the subsequent measurement work.

[0030] Furthermore, the strip-shaped hole 11 is coplanar with the stress-bearing rod 2 .

[0031] Furthermore, the diameter of the movable bolt 13 is the same as the diameter of the force bearing rod 2 .

[0032] Furthermore, it also includes a limit plate 4, which is arranged on the upper part of the force-bearing rod 2, and is L-shaped. The limit plate 4 is slidably connected to the mounting plate 1, and a movable groove 41 is opened on the surface of the limit plate 4. One end of the limit bolt 42 passes through the movable groove 41 and is fixed to the mounting plate 1, and the other end of the limit bolt 42 is fixed to the limit plate 4 through a nut.

[0033] The utility model can adjust the position of the limiting plate 4 through the limiting bolt 42, and then adjust the distance between the limiting plate 4 and the force-bearing rod 2 to adapt to wires and cables of different thicknesses.

[0034] Furthermore, one side of the handle 3 is fixed to one end of the arc spring 33 , and the other end of the arc spring 33 is fixed to the mounting plate 1 .

[0035] The arc spring 33 enables the handle 3 to automatically rebound each time it is bent.

[0036] Furthermore, fixing bolts are fixed on the back side of the mounting plate 1 .

[0037] The fixing bolts can be used to fix the device to the desktop, and can also be used to disassemble and carry the device.

[0038] The method of using this embodiment is:

[0039] The device is fixed to the desktop by fixing bolts. After fixing, the positions of the movable bolts 13 and the limit plate 4 are adjusted according to the thickness of the wires and cables. The bent end of the wires and cables is placed under the sliding nut 32. Then the handle 3 can be pulled down to allow the sliding nut 32 to press down on the wires and cables and bend them.

[0040] After the bending of the wire and cable is completed, the arc spring 33 pulls the handle 3 to reset, and then the next bending operation of the wire and cable can be carried out.

[0041] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
