DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0024] A wave resistor that is easy to load and unload, such as Figure 1-Figure 7 As shown, it includes a bottom plate 1, a square plate 2, a first rack 5, a connecting cylinder 6, a circular gear 7, a second rack 8, a double round head plate 14, a plug rod 1401, an elastic member 1402, a long nail rod 15 and a resistor body 16. The front and rear sides of the bottom plate 1 are slidably connected with the square plate 2, and the square plate 2 is used to fix the resistor body 16 front and back. The front square plate 2 is connected to the first rack 5, and the rear square plate 2 is connected to the second rack 8. A connecting cylinder 6 is provided inside the bottom plate 1, and a circular gear 7 is rotatably sleeved on the connecting cylinder 6. The first rack 5 and the second rack 8 are both meshed with the circular gear 7. When any one of the first rack 5 and the second rack 8 moves, the circular gear 7 can drive the other to move. Rounded corner holes 13 are provided on the front and rear sides of the bottom of the bottom plate 1. The front and rear sides of the bottom of the bottom plate 1 are slidably connected with the double round head plate 14, and the front double round head plate 14 is in contact with the first rack 5. The double round head plate 14 at the rear side is in close contact with the second rack 8, and the double round head plate 14 slides in the rounded hole 13 of the bottom plate 1. A plug rod 1401 is slidably connected to the double round head plate 14. A plurality of round holes are provided at the bottom of the bottom plate 1. The plug rod 1401 fits with the round holes of the bottom plate 1. The plug rod 1401 is inserted into different round holes on the bottom plate 1 to fix the double round head plate 14 at different positions. An elastic member 1402 is sleeved on the plug rod 1401. The two ends of the elastic member 1402 are respectively connected to the insertion rod 1401 and the double round head plate 14. The elastic member 1402 is used to push the insertion rod 1401 into the bottom plate 1 and is also used to reset the insertion rod 1401. Long nail rods 15 are connected to both sides of the bottom of the double round head plate 14. A resistor body 16 is placed on the bottom plate 1. The square plate 2, the first rack 5, the second rack 8, the double round head plate 14 and the long nail rod 15 are all made of metal materials with good conductive properties.

[0025] When installing the resistor, the long nail rod 15 can act as the pin of the resistor, and then the distance between the welding holes on the circuit board is not fixed. When the distance between the long nail rods 15 needs to be adjusted, the insertion rod 1401 is pulled, and the elastic member 1402 is stretched, so that the insertion rod 1401 is separated from the round hole of the bottom plate 1, and then the double round head plate 14 can slide in the rounded hole 13 of the bottom plate 1. When adjusted to a suitable position, the insertion rod 1401 is released, and the elastic member 1402 is reset from the stretched state, so that the insertion rod 1401 is inserted into the corresponding round hole on the bottom plate 1, thereby fixing the double round head plate 14. Before inserting the resistor body 16, pull the front side square plate 2 in the direction away from the bottom plate 1. At this time, the first rack 5 can move the circular gear 7. The rotation of the circular gear 7 can simultaneously drive the second rack 8 to move, so that the rear side square plate 2 moves in the direction away from the bottom plate 1 at the same time. At this time, the resistor body 16 can be inserted, and then the square plate 2 is pushed to reset. The square plate 2 can initially clamp the resistor body 16. The two levels of the resistor body 16 are respectively in contact with the square plates 2 on the front and rear sides, so the two levels of the resistor body 16 can be connected to the long nail rod 15.

[0026] On the basis of Example 1, Figure 3 and Figure 4 As shown, it also includes a plug-in frame 3, a long board 4, a limit frame 9, a first connecting block 10, a reset spring 11 and a second connecting block 12. The long boards 4 are slidably connected to both sides of the bottom plate 1. The long boards 4 are used to fix the resistor body 16 to the left and right. A plurality of limit frames 9 are arranged on both sides of the bottom plate 1. A plurality of first connecting blocks 10 are connected to the bottom of the long board 4. The first connecting block 10 slides on the limit frame 9. A reset spring 11 is sleeved on the limit frame 9. The two ends of the reset spring 11 are respectively connected to the limit frame 9 and the first connecting block 10. The reset spring 11 can enable the long board 4 to clamp the resistor body The body 16 is also used for resetting the long board 4. The front and rear sides of the long board 4 are fixedly connected with the second connecting block 12. The second connecting block 12 is located inside the square board 2. A plug-in rack 3 is slidably placed on the top of the square board 2. The square board 2 and the second connecting block 12 are both provided with circular grooves. When the square board 2 and the long board 4 fix the resistor body 16, the circular groove of the square board 2 is connected with the circular groove of the second connecting block 12. The plug-in rack 3 can be inserted into the circular grooves of the square board 2 and the second connecting block 12 at the same time. The middle part of the plug-in rack 3 is arc-shaped, and there is a gap with the square board 2. This design can facilitate the lifting of the plug-in rack 3.

[0027] In order to make the capacitor body be fixed on the bottom plate 1 more stably, the device is also provided with a long board 4. Before inserting the resistor body 16, the two long boards 4 are pulled to both sides respectively, and the first connecting block 10 at the bottom of the long board 4 slides along the limit frame 9. The reset spring 11 is squeezed by the first connecting block 10. After inserting the resistor body 16, the long board 4 is released, and the reset spring 11 is reset from the compressed state, thereby pushing the first connecting block 10 to reset the long board 4. The two long boards 4 can clamp the resistor body 16 on the bottom plate 1. In this way, under the action of the square plate 2 and the long board 4, the resistor body 16 can be fixed on the bottom plate 1. In order to prevent the square plate 2 and the long board 4 from being easily moved, the rack 3 can be inserted into the square plate 2. Since the second connecting block 12 is located in the square plate 2, the rack 3 can clamp the square plate 2 and the long board 4 at the same time.

[0028] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
