A pressure plate 42 is rotatably connected to the top surface of the screw rod 41 through a bearing, and a first knob 43 is fixedly connected to the top of the screw rod 41 .

[0024] When the screw rod 41 is driven to move up and down along the thread groove 31 by rotating the first knob 43, the screw rod 41 will drive the pressing plate 42 to move up and down, so that the pressing plate 42 can be pressed on the flange surface at the bottom of the lamp pole to fix the lamp pole.

[0025] A guide rod 44 is fixedly connected to the lower surface of the pressing plate 42 , a guide groove 32 is opened on the upper surface of the moving block 3 , and the bottom end of the guide rod 44 is located inside the guide groove 32 and is slidably connected to the guide groove 32 .

[0026] The guide rod 44 moves along the guide groove 32 to limit the upward and downward movement of the pressure plate 42 .

[0027] The transverse movement assembly 5 includes a support plate 51 fixed to the inner top wall of the support seat 1, a screw rod 52 passes through the middle of the support plate 51 and is rotatably connected via a bearing, the screw rod 52 passes through the moving block 3 and is threadedly connected to the moving block 3, and a driven bevel gear 53 is fixedly connected to one end of the screw rod 52 away from the inner wall of the support seat 1.

[0028] After the screw rod 52 of the transverse moving assembly 5 rotates, the screw rod 52 drives the moving block 3 to move along the direction of the strip-shaped opening 2 , so that the clamping assembly 4 can move along with the moving block 3 .

[0029] The transmission assembly 6 includes a vertical shaft 61 rotatably connected to the inner bottom wall of the support seat 1 , a driving bevel gear 62 is fixedly connected to the top of the vertical shaft 61 , and the driving bevel gear 62 is meshed with the driven bevel gear 53 of each transverse movement assembly 5 , and a worm gear 63 is fixedly connected to the middle of the vertical shaft 61 .

Each screw 52 drives the corresponding moving block 3 to move along the corresponding strip opening 2 toward the flange at the bottom of the lamp pole. When the pressure plate 42 of the clamping assembly 4 moves to the top of the flange, turn the screw 41 of each clamping assembly 4 in turn to drive the pressure plate 42 to descend and press on the flange surface to fix the bottom flange of the lamp pole. When disassembling, you only need to reverse each screw 41 first, and then reverse the driving shaft 71 to realize the disassembly of the lamp pole.
