The section of the clamping column 24 is arranged in a fish shape, the clamping column is wide at the upper part and narrow at the lower part, and the maximum width of the clamping column 24 is smaller than the width of the first through groove 21; during operation, the cross-section of the clamping column 24 that sets up is the fish shape, and the setting of fish shape can let the rubber bag 37 inflation that clamping column 24 is located the maximum width position and constant head tank 26 both sides lateral wall in contact with each other, can release unnecessary gas and get into rubber bag 37 both sides department, also can guarantee the stability of roof 11 on the horizontal direction when guaranteeing to adsorb between first magnetic path 33 and the magnetic ball 35 to clamping column 24 fixed stable.

An oil bag 41 is fixedly connected to the side wall of the second cavity 34 close to the rotating shaft 23; an oil outlet cavity 42 is formed in the end part of the clamping column 24; a group of oil outlet holes 43 are formed in the top end of the clamping column 24, and the oil outlet holes 43 are communicated with the oil outlet cavity 42; the side wall of the push plate 31 is fixedly connected with a magnetic layer 4; the magnetic layer 4 and the magnetic balls 35 repel each other; a first spring 44 is fixedly connected in the oil bag 41; the during operation, when axis of rotation 23 rotates and promotes push plate 31 through screens post 24, this moment because of the magnetic layer 4 and the magnetic ball 35 mutual repulsion of push plate 31, the magnetic ball 35 can be to the direction removal of keeping away from push plate 31, and then extrude oil pocket 41, inside lubrication can get into out in the oil pocket 42 when oil pocket 41 receives the extrusion, then spout through oil outlet 43, lubricate screens post 24 top, can reduce screens post 24 and promote the frictional force of push plate 31, reduce the energy consumption.

Example two:

as shown in fig. 9, in a first comparative example, as another embodiment of the present invention, a sponge layer 45 is fixed on the inner wall of the opening of the oil outlet 43; the during operation, in order to prevent that lubricating oil from directly spouting from oil outlet 43, the extravagant condition appears, the rigid coupling has sponge layer 45 on oil outlet 43 opening inner wall, and sponge layer 45 can slowly ooze after absorbing lubricating oil to on the lubricated screens post 24 top, can practice thrift the use of lubricating oil at the lubricated effect of make full use of lubricating oil.

The working principle is as follows: when the control device needs to be placed into the power box 1, a lead can be connected to the control device outside the power box 1, when the connection of the lead does not need to be released, the control device is placed into the power box 1 from the top end of the power box 1, then the fixing rod 14 of the fixing plate 12 extends into the L-shaped groove 13 of the fixing plate 12, then the fixing rod 14 extends into the L-shaped groove 13 through the mutual parallel of the inclined surfaces of the clamping block 15 and the sliding block 16, the clamping block 15 firstly pushes the sliding block 16 to slide in the L-shaped groove 13, then the clamping block 15 is clamped into the clamping groove 17 under the action of the spring of the sliding block 16, so that the top plate 11 is combined, and when the top plate 11 is combined, the lead is clamped through the half L-shaped pipe of the fixing plate 12; when the top plate 11 is fixed at the top end of the power box 1, the rotary table 22 is rotated to enable the clamping column 24 to be in a vertical state, then the first through groove 21 at the bottom end of the fixing plate 12 is aligned with the rotary shaft 23 and the clamping column 24, the clamping column 24 enters the first cavity 27, the L-shaped plate 28 is aligned with the first groove, then the L-shaped plate 28 extends into the first groove, the top plate 11 is pushed towards the fixing block 2, the end part of the L-shaped plate 28 is clamped into the second groove, then the clamping column 24 is clamped into the positioning groove 26 in the reverse rotation of the rotary shaft 23, and then the vertical direction and the horizontal direction of the top plate 11 are doubly fixed, so that the fixing state of the top plate 11 is ensured, the top plate is prevented from being influenced by the external environment, and the working state of the power box 1 is ensured; when the top plate 11 is damaged, because the top plate 11 is combined, in order to save raw materials, the damaged fixed plate 12 is selected, the rotating shaft 23 is rotated forwardly firstly, the clamping column 24 is separated from the positioning groove 26, the clamping column 24 is contacted with the push plate 31, then the push plate 31 is pushed by the clamping column 24, the push plate 31 moves to move the slider 16 through the connecting column 32, the clamping block 15 is separated from the clamping groove 17, the fixation between the fixed plates 12 is released, then the fixed plate 12 behind the damaged fixed plate 12 is pushed firstly and moves in the direction far away from the fixed block 2, then the fixed plate 12 is taken down, then the damaged fixed plate 12 is pushed to move in the direction far away from the fixed block 2, and then the damaged fixed plate 12 is taken down, at the moment, a new fixed plate 12 is installed at the damaged position through the clamping assembly, so that the waste of resources can be further prevented while the replacement is convenient; because the clamping column 24 is located in the positioning groove 26 through the rotation of the rotating shaft 23, and then the top plate 11 can be horizontally fixed, but in order to prevent the loosening condition, the clamping column 24 is located in the positioning groove 26, at the moment, because the first magnetic block 33 and the magnetic ball 35 attract each other, the magnetic ball 35 can move in the second cavity 34 and further extrude the air bag 36, the gas of the air bag 36 can enter the rubber bag 37, and then the rubber bag 37 is expanded, gaps between the clamping column 24 and the side walls of the two sides of the positioning groove 26 can be filled, and then the stability of the top plate 11 in the horizontal direction can be ensured, and the shaking condition can not occur; when the axis of rotation 23 rotates and promotes push plate 31 through screens post 24, this moment because of the magnetic layer 4 and the mutual repulsion of magnetic ball 35 of push plate 31, magnetic ball 35 can remove to the direction of keeping away from push plate 31, and then extrude oil pocket 41, inside lubrication can get into out the oil pocket 42 when oil pocket 41 receives the extrusion, then spout through oil outlet 43, lubricate screens post 24 top, can reduce screens post 24 and promote the frictional force of push plate 31, reduce the energy consumption.
