[0007] Preferably, the top of the second mounting long block is fixedly connected to a wrapping plate.

[0008] Preferably, the wrapping plate is arranged in a semicircular arc shape.

[0009] Preferably, the end of the screw rod is fixedly connected to a knob.

[0010] Preferably, anti-slip protrusions are evenly fixed on the knob.

[0011] Preferably, it also includes support rods, which are fixed to the bottom wall of the main workbench and are evenly arranged in four groups.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0013] By combining the slide groove, the propulsion cylinder, the installation long block, the installation plate, the second installation long block, the limit block and the screw rod, the power cable can be stretched and tensioned while being wound, without reducing the power cable.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 As shown, a tensioning device for power cable installation comprises a main body workbench 1, a motor 2 is arranged on the side wall of the main body workbench 1, a rotating shaft 3 is extended from the output end of the motor 2, a plurality of slide grooves 4 are evenly arranged on the rotating shaft 3, a propulsion cylinder 5 is sleeved on the rotating shaft 3, a plurality of mounting long blocks 6 are arranged on the outer wall of the propulsion cylinder 5 corresponding to the slide groove 4, the side wall of the mounting long block 6 is movably connected to the mounting plate 7, the top of the mounting plate 7 is movably connected to the mounting long block 2 8, the mounting long block 2 8 extends through the slide groove 4, the end of the mounting long block 2 8 is fixedly connected to the limiting block 9, the propulsion cylinder 5 is threadedly penetrated by the screw 10, and the screw 10 is connected to the end bearing of the rotating shaft 3.

[0021] like Figure 1-4As shown, the top of the installation long block 2 8 is fixedly connected to a wrapping plate 11, the wrapping plate 11 is arranged in a semicircular arc shape, the end of the screw rod 10 is fixedly connected to a knob 12, and the knob 12 is evenly fixed with anti-slip protrusions 13, and also includes a support rod 14, the support rod 14 is fixedly connected to the bottom wall of the main workbench 1 and is evenly arranged in four groups.

[0022] During specific use, the power cable is wound around several groups of winding plates 11, and then the motor 2 is started to drive the rotating shaft 3 to rotate, thereby achieving a winding effect. When tensioning is required, the knob 12 is rotated, and the knob 12 drives the screw 10 to rotate to generate a force to push the propulsion tube 5 forward. At this time, the mounting plate 7 pushes the winding plate 11 to move upward along the slide groove 4 through the mounting long block 2 8 to achieve a tensioning effect. In summary, the device can achieve the effect of winding the power cable while stretching and tensioning the power cable through a combination of the slide groove 4, the propulsion tube 5, the mounting long block 6, the mounting plate 7, the mounting long block 2 8, the limit block 9 and the screw 10, without reducing the power cable.
