In this embodiment, if the number of movable columns 2 needs to be increased according to the actual situation, a worker removes the baffle 43 from the inner side of the clamping block 44, releases the limitation on the movable columns 2, after fixing the fixed column 3, another worker supports the rest of the parts, then removes the movable columns 2 from the inner sides of the connecting rod 6 and the movable rod one 37, sequentially splices the movable columns 2 according to the actual working situation, then the fixing plate two at one end is clamped with the clamping plate one 38, and the clamping plate two at the other end is clamped with the connecting rod 6, thereby achieving the purpose of expanding the rail length.
Work of principle of: referring to fig. 1-13 in the initial state, a worker holds the pull rod 121 with hand to pull the box-type electric power safety stretching fence net to a designated working place, locks the universal wheel 5 at the bottom of the bottom plate 11, places the palm at the top of the support plate 132, pulls the holding rod 133 with four fingers to drive the two round rods 134 to move out from the inner sides of the two door plates 16, continues to drive the top plate 13 to rotate until the top plate 13 is positioned at the back of the back plate 12, then pulls the left side plate 15 to move to the side far from the bottom plate 11, the left side plate 15 drives the left side door plate 16 and the movable rod two 27 on the front left side of the back plate 12 to move to the side far from the bottom plate 11 through the two connecting rods 6 and the two clamping plates two 28, The movable rod II 27 positioned on the left side of the front surface of the back plate 12 drives the two cross rods II 26 to respectively rotate forward by taking the two fixed posts II 22 as the circle centers through the two sliding posts II 24, meanwhile, the two cross rods II 26 drive the movable rod I37 positioned on the left side of the front surface of the back plate 12 to move to one side far away from the fixed rod I31 through the two fixed posts II 22 and the fixed rod II 21, the movable rod I37 positioned on the left side of the front surface of the back plate 12 drives the two cross rods I36 to respectively rotate forward by taking the two fixed posts I32 as the circle centers through the two sliding posts I34, when the two cross rods positioned on the left side of the back plate 12 and close to the bottom plate 11 are contacted with the tops of the support posts 78, the left side plate 15 is stopped from being pulled, Then, the first cross bar 36 close to the bottom plate 11 is pressed by hand to press the strut 78 to move in the direction close to the ground, the strut 78 pushes the link block 72 and the four support bars 73 to move to the side close to the ground, when the bottom of the link block 72 is aligned with the top wall of the side groove 77, the four connection blocks 76 drive the four support bars 73 away from each other under the action of elastic force, when the bottom of the link block 72 is aligned with the bottom wall of the movable bar 37, the four support bars 73 are contacted with the ground, then the second cross bar 26 close to the bottom plate 11 is pressed by hand to press the strut 78 to move in the direction close to the ground, the strut 78 pushes the link block 72 and the four support bars 73 to move to the side close to the ground, When the bottom of the link block 72 is aligned with the top wall of the side groove 77, the four connection blocks 76 drive the four support rods 73 away from each other under the action of elastic force, when the bottom of the link block 72 is aligned with the bottom wall of the movable rod two 27, the four support rods 73 are in contact with the ground, the movable rail 2 is stably supported on the ground, then the universal wheels 5 at the backs of the left side plate 15 and the right side plate 14 are locked, because all the fixed rail 3 and the movable rail 2 have the same structure, the worker pulls the right side plate 14 to move to the side far from the bottom plate 11, the fixed rail 3 and the movable rail 2 positioned at the front of the back plate 12 are unfolded and stably supported on the ground, then the four lock rods 122 are sequentially rotated ninety degrees by hand so that the four lock rods 122 are completely moved into the inner sides of the locking grooves 123, Then the four lock bars 122 are pulled to the back of the backboard 12 to release the restriction on the left side plate 15 and the right side plate 14, then the left side plate 15 and the right side plate 14 are sequentially driven by hands to move to the side far away from the backboard 12, the movable rail 2 and the fixed rail 3 which are positioned on the right side of the left side plate 15 and close to the backboard 12 and the movable rail 2 and the fixed rail 3 which are positioned on the left side of the right side plate 14 and close to the backboard 12 are unfolded and stably supported on the ground, then the two universal wheels 5 on the opposite sides of the two door plates 16 are locked, then the two door plates 16 are driven by hands to move to the side close to each other until the two door plates 16 are attached, the movable rail 2 and
