[0026] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:

[0027] As Figures 1-3 shown, the utility model provides a connecting fitting for electric power engineering, including a base 1. A lower fixing plate 15 is fixedly connected to the upper surface of the base 1. A lower clamping plate 14 is fixedly connected to the upper surface of the lower fixing plate 15. A plurality of screws 13 are arranged on the upper surface of the lower fixing plate 15, and the outer wall of the screw 13 is threadedly connected to the base 1. The outer wall of a guide post 19 is slidably connected to a push block 21. A wire 7 is movably connected to the upper surface of the lower clamping plate 14. An upper clamping plate 6 is movably connected to the upper side of the wire 7. An upper fixing plate 12 is fixedly connected to the upper surface of the upper clamping plate 6. A connecting sleeve 22 is fixedly connected to the right side of the base 1. A rotating seat 2 is movably connected to the upper surface of the connecting sleeve 22. A fixing sleeve 9 is fixedly connected to the upper side of the inner wall of the rotating seat 2, and the upper end of the fixing sleeve 9 is fixedly connected to the rotating seat 2. The rear side of a knob 3 is rotatably connected to the rotating seat 2. A worm gear 11 is rotatably connected to the lower end of the fixing sleeve 9. Threaded columns 10 penetrate and are threadedly connected to the upper and lower sides of the worm gear 11, and the outer wall of the threaded column 10 is threadedly connected to the fixing sleeve 9. A worm 8 is meshed with the outer wall of the worm gear 11, and the front end of the worm 8 is fixedly connected to the knob 3. By rotating the knob 3, the knob 3 drives the worm 8 to rotate, the worm 8 drives the worm gear 11 to rotate, and the worm gear 11 cooperates with the threaded columns 10. When the worm gear 11 rotates, the internal threads drive the threaded columns 10 to rotate. However, since the fixing sleeve 9 limits the threaded columns 10, the threaded columns 10 can be driven to rise or fall, thereby driving the upper clamping plate 6 to move downward to fix wires 7 of different sizes.

[0028] As Figures 4-6As shown in the figure, the utility model provides a technical solution: Preferably, a fixed block 4 is fixedly connected to the left side of the base 1, a connecting block 5 is fixedly connected to the left side of the rotating seat 2, a support plate 16 is fixedly connected to the lower side of the connecting block 5, a clamping block 17 is fixedly connected to the lower end of the support plate 16, a push plate 18 is slidably connected to the left side of the fixed block 4, a push block 21 is fixedly connected to the right side of the push plate 18, the right side of the push block 21 is movably connected to the support plate 16, the outer wall of the worm gear 11 is rotatably connected to the rotating seat 2, a guide post 19 is fixedly connected to the right side of the inner wall of the fixed block 4, a first spring 20 is sleeved on the outer wall of the guide post 19, the left end of the first spring 20 is fixedly connected to the fixed block 4, and the right end of the first spring 20 is fixedly connected to the push block 21. A rotating block 26 is fixedly connected to the right side of the rotating seat 2, the outer wall of the rotating block 26 is slidably connected to the connecting sleeve 22, the lower surface of the push block 21 is movably connected to the clamping block 17, a limiting plate 25 is fixedly connected to the lower end of the rotating block 26, the left and right sides of the limiting plate 25 are slidably connected to the connecting sleeve 22, the left and right sides of the baffle plate 23 are fixedly connected to the connecting sleeve 22, a second spring 24 is fixedly connected to the lower surface of the limiting plate 25, the outer wall of the second spring 24 is movably connected to the connecting sleeve 22, and the lower end of the second spring 24 is fixedly connected to the baffle plate 23. By pulling the push plate 18, the support plate 16 is closed. When the push plate 18 is released, the first spring 20 inside the fixed block 4 will push the push block 21 forward. The push block 21 and the clamping block 17 cooperate with each other to limit the support plate 16, thereby fixing the rotating seat 2. If the push plate 18 is pulled open, the second spring 24 will pull the limiting plate 25 to move, thereby driving the rotating seat 2 to rotate and quickly opening the device.

[0029] Next, the working principle of the connecting fitting for the power engineering will be specifically described.

[0030] As Figures 1-6 shown in the figure, when the push plate 18 is pulled open, the push block 21 will move on the guide post 19, and the second spring 24 will pull the limiting plate 25 to move, thereby driving the rotating seat 2 to rotate and quickly opening the device. Place the wire 7 on the lower clamping plate 14, then close the rotating seat 2, pull the push plate 18 to close the support plate 16. When the push plate 18 is released, the first spring 20 inside the fixed block 4 will push the push block 21 forward. The push block 21 and the clamping block 17 cooperate with each other to limit the support plate 16, thereby fixing the rotating seat 2. Then, by rotating the knob 3, the knob 3 drives the worm 8 to rotate, the worm 8 drives the worm gear 11 to rotate. The worm gear 11 and the threaded column 10 cooperate with each other. When the worm gear 11 rotates, the internal thread will drive the threaded column 10 to rotate. However, since the fixed sleeve 9 limits the threaded column 10, the threaded column 10 can be driven to rise or fall, thereby driving the upper clamping plate 6 to move downward to fix wires 7 of different sizes.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
