[0029] Please see Figures 1-5A lifting terminal block to prevent loose wiring includes a terminal block body 1, a housing 2, a movable groove 3 and a wire-passing groove 4, a movable block 5 slidingly disposed inside the movable groove 3, a connecting groove 6 inside the movable block 5, a connecting plate 7 disposed inside the connecting groove 6, a fixing block 8 at one end of the connecting plate 7 and a connecting block 9 at the other end, a snap-fit ​​block 10 on the connecting block 9, a snap-fit ​​groove 11 on the housing 2, and a pin 12 connected to the bottom of the connecting block 9. The wire-passing groove 4... A limiting sleeve 13 is provided on one side, and an adjustment groove 14 is provided around the limiting sleeve 13. A clamping rod 15 is slidably provided around the limiting sleeve 13. A clamping plate 16 is provided at one end of the clamping rod 15, and a clamping block 17 is provided at the other end extending into the adjustment groove 14. A countersunk hole 18 is provided on the housing 2. A moving bolt 19 is rotatably provided in the countersunk hole 18. One end of the moving bolt 19 is rotatably connected to the moving block 5. A moving spring 20 is provided between the moving bolt 19 and the countersunk hole 18. An anti-slip mark 21 is provided on the connecting plate 7.

[0030] In this embodiment, the downward movement of the connecting plate 7 and the connecting block 9 is restricted by the cooperation of the snap-fit ​​block 10 and the snap-fit ​​groove 11, and the upward movement of the connecting plate 7 and the connecting block 9 is restricted by the fixing block 8. Therefore, the connecting plate 7 and the connecting block 9 are fixed in the position within the moving groove 3. The external wiring is passed through the limiting sleeve 13 and extended into the connecting groove 6. The moving bolt 19 is rotated, and the moving bolt 19 drives the moving block 5 to move upward within the moving groove 3. The bottom of the connecting groove 6 of the moving block 5 is supported upward. The external wiring and the connecting plate 7 are connected and fixed by the anti-slip mark 21, which improves the connection stability. The moving spring 20 is in a compressed state, which improves the thread engagement force between the housing 2 and the moving bolt 19, thereby making the connection between the wiring terminals stable.

[0031] Please see Figures 4-5 As one embodiment of the limiting sleeve 13: an adjusting block 22 is slidably provided in the adjusting groove 14, the contact surface between the adjusting block 22 and the clamping block 17 is an inclined surface, an adjusting spring 23 is provided between the adjusting groove 14 and the clamping block 17, an adjusting rod 24 is provided at one end of the adjusting block 22, an adjusting plate 25 is connected between the adjusting rods 24, an adjusting sleeve 26 is threadedly connected to the outside of the limiting sleeve 13, and the adjusting plate 25 is rotatably disposed in the adjusting sleeve 26.

[0032] More specifically, after the external wiring is connected, rotate the adjusting sleeve 26. The adjusting sleeve 26 drives the limiting sleeve 13 to rotate, causing the adjusting plate 25, adjusting rod 24, and adjusting block 22 to move towards the clamping block 17 on the limiting sleeve 13. The adjusting block 22 presses the clamping block 17, causing the clamping block 17 to drive the clamping rod 15 and clamping plate 16 to press the external wiring and compress the adjusting spring 23, thereby preventing the external wiring from loosening. When disassembling the external wiring, rotate the adjusting sleeve 26 in the opposite direction. The clamping block 17 resets under the elastic force of the adjusting spring 23, causing the adjusting rod 24 and adjusting plate 25 to move outward and reset. Rotate the moving bolt 19 in the opposite direction to disassemble the external wiring.

[0033] In summary, during use or operation of the overall equipment: the downward movement of the connecting plate 7 and the connecting block 9 is restricted by the cooperation of the snap-fit ​​block 10 and the snap-fit ​​groove 11, and the upward movement of the connecting plate 7 and the connecting block 9 is restricted by the fixing block 8. Therefore, the connecting plate 7 and the connecting block 9 are fixed in the position within the moving groove 3. The external wiring is passed through the limiting sleeve 13 and extended into the connecting groove 6. The moving bolt 19 is rotated, and the moving bolt 19 drives the moving block 5 to move upward within the moving groove 3. The bottom of the connecting groove 6 of the moving block 5 is supported upward. The external wiring and the connecting plate 7 are connected and fixed by the anti-slip mark 21, which improves the connection stability. The moving spring 20 is in a compressed state, which improves the thread engagement force between the housing 2 and the moving bolt 19, thereby making the connection between the wiring terminals stable.

[0034] After the external wiring is connected, rotate the adjusting sleeve 26. The adjusting sleeve 26 drives the limiting sleeve 13 to rotate, causing the adjusting plate 25, adjusting rod 24 and adjusting block 22 to move towards the clamping block 17 on the limiting sleeve 13. The adjusting block 22 presses the clamping block 17, causing the clamping block 17 to drive the clamping rod 15 and clamping plate 16 to press the external wiring and compress the adjusting spring 23, thereby preventing the external wiring from loosening. When disassembling the external wiring, rotate the adjusting sleeve 26 in the opposite direction. The clamping block 17 resets under the elastic force of the adjusting spring 23, causing the adjusting rod 24 and adjusting plate 25 to move outward and reset. Rotate the moving bolt 19 in the opposite direction to disassemble the external wiring.
