The anti-slip pad can increase the stability of the fixed seat 100 when it is placed on the tabletop. The first rubber plate 130c is used to increase the friction between the first clamping plate 130 and the copper-clad steel wire. By passing the wire through between the two first clamping plates 130, rotating the first knob 150 drives the first left-right threaded rod 150a to rotate, and using the screw rod structure to push the two first sliding plates 130a closer to each other. The two first sliding plates 130a drive the two first clamping plates 130 to approach each other and clamp the wire, and one end of the wire is clamped and fixed at the top of the fixed seat 100.

[0031] A rotating plate 210 is installed at the front end of the movable seat 200. The rotating plate 210 is rotatably connected inside the rotating groove 110. An activity groove 220 is formed at the bottom of the movable seat 200. The arc-shaped plate 120 is located inside the activity groove 220. A first rotating rod 210a is installed at the top of the movable seat 200. The top end of the first rotating rod 210a extends out of the top of the fixed seat 100 and is installed with a turntable 210a-1. Two fixing plates 210a-2 are symmetrically installed at the top of the turntable 210a-1. A second rotating rod 210b is installed at the bottom of the rotating plate 210. The bottom end of the second rotating rod 210b extends out of the bottom of the fixed seat 100 and is installed with a first gear 210b-1. Two second clamping plates 230 are symmetrically arranged at the top of the movable seat 200. A second sliding groove 240 is formed at the top of the movable seat 200. A second knob 250 is rotatably connected to the side wall of the movable seat 200. A second left-right threaded screw rod 250a is installed on the side wall of the second knob 250. The second left-right threaded screw rod 250a extends into the second sliding groove 240. A second sliding plate 230a is installed at the bottom of the second clamping plate 230. The second sliding plate 230a is located inside the second sliding groove 240. A second threaded hole 230b is formed in the side wall of the second sliding plate 230a.

The bottom of the second support column 260 has rollers. While the second support column 260 supports the movable seat 200, it does not affect the rotation of the movable seat 200. A fixing frame 270 is installed at the bottom of the movable seat 200 at a position below the activity groove 220. A through hole 270a is formed at the bottom of the fixing frame 270. A positioning hole 120b is formed at the corresponding position of the bottom of the arc-shaped plate 120 and the fixing frame 270. The positioning hole 120b is located at the middle position of the bottom of the arc-shaped plate 120. The second rubber plate 230c is used to increase the friction between the second clamping plate 230 and the copper-clad steel wire. By passing the wire through between the two second clamping plates 230 and through between the two turntables 210a-1, rotating the second knob 250 drives the second left-right threaded screw rod 250a to rotate. Using the screw rod structure to push the two second sliding plates 230a closer to each other, the two second sliding plates 230a drive the two second clamping plates 230 to move closer to each other and clamp the wire, and one end of the wire is clamped and fixed at the top of the movable seat 200.

[0032] The driving assembly 300 includes a handle 310 rotatably connected to the side wall of the fixed seat 100, a cross plate 320 installed at the front end of the fixed seat 100, and a second gear 330 rotatably connected to the bottom of the fixed seat 100 and meshed with the first gear 210b-1. A third rotating rod 310a is installed on the side wall of the handle 310, and a first bevel gear 310b is installed at the other end of the third rotating rod 310a. A second bevel gear 320a is rotatably connected to the top of the cross plate 320, and the second bevel gear 320a is meshed with the first bevel gear 310b. A pulley 320b is rotatably connected to the bottom of the cross plate 320, and the pulley 320b is coaxially and fixedly connected to the second bevel gear 320a. A belt is connected between the pulley 320b and the second gear 330. By rotating the handle 310, the third rotating rod 310a and the first bevel gear 310b are driven to rotate. When the first bevel gear 310b rotates, the teeth drive the second bevel gear 320a and the pulley 320b to rotate. When the pulley 320b rotates, the belt drives the second gear 330 to rotate. When the second gear 330 rotates, it drives the first gear 210b-1 to rotate, and then drives the rotating plate 210 to rotate inside the rotating groove 110. The movable seat 200 drives one end of the wire to rotate around the rotating plate 210, and at the same time, the wire bends with one of the fixing plates 210a-2 as a fulcrum.

[0033] The positioning assembly 400 includes a lifting plate 410 located inside the fixed frame 270, a positioning block 420 installed on the top of the lifting plate 410, a sliding rod 430 installed at the bottom of the lifting plate 410 corresponding to the through hole 270a, and a spring 440 installed at the bottom of the lifting plate 410. The positioning block 420 extends into the positioning hole 120b. The left and right ends of the positioning block 420 have arc-shaped surfaces 420a. In the initial state, the movable seat 200 is flush with the fixed seat 100, and the positioning block 420 is located inside the positioning hole 120b. When the movable seat 200 rotates, the side wall of the positioning hole 120b squeezes the positioning block 420 and the lifting plate 410 to move downward along the arc-shaped surface 420a. When the lifting plate 410 moves downward, it drives the sliding rod 430 to penetrate downward through the through hole 270a and squeezes the spring 440. As the movable seat 200 drives the lifting plate 410 to rotate, the top of the positioning block 420 always abuts against the bottom of the arc-shaped plate 120 until the movable seat 200 resets. When the movable seat 200 is flush with the fixed seat 100 again, the positioning block 420 is located directly below the positioning hole 120b. At this time, the spring 440 rebounds and pushes the lifting plate 410 and the positioning block 420 to move upward, and the positioning block 420 is inserted into the positioning hole 120b. The top of the positioning block 420 collides with the top of the positioning hole 120b, making a sound and a vibration sensation, reminding the staff that the wire has been returned to the correct position.

[0034] Combined Figure 1 - Figure 6, a copper-clad steel bending testing machine according to this embodiment, when in use, the wire is sequentially passed through two first clamping plates 130, two fixing plates 210a-2 and two second clamping plates 230. Rotate the first knob 150 to drive the first left-right threaded screw rod 150a to rotate, and use the screw rod structure to push the two first clamping plates 130 closer to each other and clamp one end of the wire. Rotate the second knob 250 to drive the second left-right threaded screw rod 250a to rotate, and use the screw rod structure to push the two second clamping plates 230 closer to each other and clamp the other end of the wire. At this time, rotate the handle 310 in the forward direction to drive the second gear 330 to rotate forward. The second gear 330 drives the first gear 210b-1 to rotate, driving the movable seat 200 to rotate around the rotating plate 210. The movable seat 200 drives one end of the wire to bend to the left with one of the fixing plates 210a-2 as the fulcrum. When the handle 310 is rotated in the reverse direction, the handle 310 drives the second gear 330 to rotate in the reverse direction, driving the movable seat 200 to rotate to the right around the rotating plate 210, and then driving one end of the wire to rotate to the right with the other fixing plate 210a-2 as the fulcrum. By observing the position of the movable seat 200 on the positioning hole 120b, the rotation angle of the movable seat 200, that is, the bending angle of the wire, can be judged, improving the accuracy during the wire bending test.

[0035] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present invention can be combined with each other in any way.
