[0029] Reference Figure 1-4 As shown, this embodiment discloses a support device 2 including a placement plate 21, with a plurality of first support plates 22 fixedly connected to one side of the placement plate 21, a second bolt 23 threadedly connected to one side of the placement plate 21, a connecting plate 24 rotatably connected to one side of the second bolt 23, a second support plate 25 fixedly connected to one side of the connecting plate 24, and the second support plate 25 abutting against the first support plate 22 and the wire 5. When the wire 5 needs to be connected, it is inserted into the hole of the housing 1, and then the first bolt 4 is rotated to tighten the wire 5 inside the housing 1, and then the wire 5 is firmly fixed to the terminal block. When removing the wire 5, the first bolt 4 is moved away from the wire 5, and then the wire 5 is pulled out. After the wire 5 is inserted into the shell 1 and fixed, the second bolt 23 inside the placement plate 21 can be rotated to make the second bolt 23 drive the connecting plate 24 to move, and then the connecting plate 24 drives the second support plate 25 close to the wire 5, and then the second support plate 25 squeezes the wire 5 to the first support plate 22, and then abuts and fixes the wire 5, and then completes the fixed support of the wire 5 close to the shell 1. By using the supporting device 2, the wire 5 fixed to the inside of the shell 1 can be supported and fixed, so that the connection between the wire 5 and the shell 1 cannot be bent, and the connection between the wire 5 and the shell 1 is prevented from being easily bent by force. Then, after multiple bendings, the protective cover at the connection between the wire 5 and the shell 1 is damaged, thereby improving the use effect of the terminal block.
[0030] Reference Figure 1-4As shown, this embodiment discloses that one side of the second bolt 23 is fixedly connected to a plurality of anti-slide blocks 26, and the plurality of anti-slide blocks 26 are equidistantly arranged on one side of the second bolt 23. By using the anti-slide blocks 26, the friction between the second bolt 23 and the operator is increased, making it easier for the operator to rotate the second bolt 23. A limiting frame 27 is fixedly connected to one side of the placement block, and the limiting frame 27 is slidably connected to the connecting plate 24. By using the limiting frame 27, the movement trajectory of the connecting plate 24 is restricted, so that the connecting plate 24 can more stably drive the second support plate 25 to move. A rubber pad 28 is fixedly connected to the side of the second support plate 25 close to the first support plate 22, and the size of the rubber pad 28 is adapted to the size of the second support plate 25. By using the rubber pad 28, the friction between the second support plate 25 and the wire 5 is increased, so that the second support plate 25 can be better abutted and fixed to the wire 5.
[0031] Reference Figure 1-4 As shown, this embodiment discloses that the fixing assembly 3 includes a square tube 31, one side of which is fixedly connected to the housing 1, a third bolt 32 is threadedly inserted into one side of the square tube 31, and a fixing block 33 is threadedly connected to one side of the third bolt 32, and the fixing block 33 is fixedly connected to the placement plate 21. When using the support device 2, the placement plate 21 can be moved so that the fixing blocks 33 on both sides of the placement plate 21 are inserted into the square tube 31, and then the third bolt 32 is rotated so that the third bolt 32 passes through the square tube 31 and is fixed to the fixing block 33, thereby completing the fixation of the placement plate 21. By using the fixing assembly 3, the support device 2 can be quickly fixed to the housing 1, making it more convenient for the operator to use the support device 2.
[0032] Reference Figure 1-4 As shown, this embodiment discloses that one side of the fixing block 33 is fixedly connected to a trapezoidal block 34, and the size of the trapezoidal block 34 on the side away from the fixing block 33 is smaller than the size on the other side. By using the trapezoidal block 34, the size of one side of the fixing block 33 is reduced, so that the fixing block 33 can be more easily inserted into the square tube 31. One side of the fixing block 33 is fixedly connected to a reinforcing plate 35, and one side of the reinforcing plate 35 is fixedly connected to the placement plate 21.

One side of the third bolt 32 is abutted with a gasket 36, and one side of the gasket 36 is abutted with the third bolt 32. By using the gasket 36, the contact area between the third bolt 32 and the square tube 31 is increased, so that the third bolt 32 can fix the fixing block 33 more firmly.
[0033] Working principle: When the wire 5 needs to be connected, insert it into the hole of the housing 1, and then tighten the wire 5 inside the housing 1 by turning the first bolt 4, and then firmly fix the wire 5 on the terminal block. When removing the wire 5, keep the first bolt 4 away from the wire 5, and then pull the wire 5 out. After the wire 5 is inserted into the shell 1 and fixed, the second bolt 23 inside the placement plate 21 can be rotated to make the second bolt 23 drive the connecting plate 24 to move. At this time, the movement trajectory of the connecting plate 24 is limited by using the limit frame 27, and then the connecting plate 24 drives the second support plate 25 to approach the wire 5. Then, the second support plate 25 squeezes the wire 5 to the first support plate 22 and abuts and fixes it with the wire 5, and then completes the fixed support of the wire 5 close to the shell 1. By using the support device 2, the wire 5 fixed to the inside of the shell 1 can be supported and fixed, so that the connection between the wire 5 and the shell 1 cannot be bent, and the connection between the wire 5 and the shell 1 is prevented from being easily bent by force. Then, after multiple bendings, the protective cover at the connection between the wire 5 and the shell 1 is damaged, thereby improving the use effect of the terminal block.
