[0019] Furthermore, a rotating handle 31 is fixedly connected to one end of the reciprocating screw rod 3 , and the reciprocating screw rod 3 can be driven to rotate by rotating the rotating handle 31 .

[0020] Furthermore, the two sliders 202 are both stuck in the slide groove 101 , and the sliders 202 can slide back and forth along the slide groove 101 .

[0021] Furthermore, a storage cavity 201 is provided inside one of the clamping blocks 2 , and the storage cavity 201 can enable the first bevel gear 23 to mesh with the second bevel gear 41 .

[0022] Furthermore, the other sides of the outer surfaces of the two clamping blocks 2 are rotatably connected with auxiliary rollers 5, and the auxiliary rollers 5 are rotatably connected to the clamping blocks 2 through bearings. The auxiliary rollers 5 can support the camouflage net.

[0023] Specifically, when using the utility model, first, by rotating the rotating handle 31, the reciprocating screw rod 3 can be driven to rotate. When the reciprocating screw rod 3 can drive the slider 202 to slide back and forth along the slide groove 101, the slider 202 will drive the clamping block 2 to slide inward, thereby clamping the camouflage net. When in use, it can be quickly disassembled to camouflage the vehicle. When the camouflage is completed and the camouflage net needs to be rolled up, the motor 21 is first started to drive the transmission shaft 22 to rotate. The transmission shaft 22 rotates to drive the first bevel gear 23 to rotate. The first bevel gear 23 drives the second bevel gear 41 to rotate through meshing. The second bevel gear 41 rotates and drives the first winding roller 4 to rotate, thereby the camouflage net can be rolled up, thereby improving the winding efficiency. When the camouflage net contacts the camouflage net through the squeezing roller 8 during rotation, the squeezing roller 8 will compress the spring 63 through the connecting block 7, so that the connecting block 7 can slide along the limiting block 62 through the limiting groove 701, thereby preventing the camouflage net from being too loose during the rolling process, resulting in the camouflage net being squeezed and wrinkled.
