As shown in fig. 1 and 6, the connection member may optionally include a fixing rod 5, a moving shaft 310, a connection shaft 320, a support rod 330, a rotation shaft 340, and a handle 350.

The lower extreme fixed setting of dead lever 5 is on lower fixed block 4, and the upper end of dead lever 5 passes fixed block 3, and the position cover that dead lever 5 is located fixed block 3 top is equipped with spring 510, and dead lever 5 is provided with two with respect to lower fixed block 4 front and back symmetry.

One end of the moving shaft 310 is connected with the supporting rod 330 through the connecting shaft 320, the other end is movably connected with the upper fixing block 3, the supporting rod 330 is fixedly connected with the handle 350, the handle 350 is rotatably connected with the rotating shaft 340, and the connecting shaft 320 is horizontally arranged with the rotating shaft 340.

Specifically, the fixing rod 5 is used for positioning the upper fixing block 3 and the lower fixing block 4, so that the fixing block 3 and the lower fixing block 4 do not deviate in the vertical direction, the filter membrane mesh 610 and the lower outlet of the funnel 2 are aligned in the vertical direction, and milk is further ensured not to be missed. The elastic deformation of the spring 510 can apply force to the upper fixed block 3, so that the upper fixed block 3 is favorably pressed with the lower fixed block 4 when falling, the loosening is difficult, and the leakage of milk is avoided.

The bracing piece 330 is fixedly connected with the handle 350, and the junction of bracing piece 330 and handle 350 is right angle, and handle 350 rotates with the one end of pivot 340 to be connected, and the other end and the lower fixed block 4 fixed connection of pivot 340, bracing piece 330 and connecting axle 320 fixed connection, connecting axle 320 and motion axle 310 fixed connection, one kind of realizable connected mode of motion axle 310 and last fixed block: the moving shaft 310 is slidably connected with the bottom of the upper fixed block 3 through a horizontal linear chute 360, the length direction of the linear chute 360 is perpendicular to the length direction of the filter membrane slide 6, and the upper end of the moving shaft 310 extends into the linear chute, so that when the moving shaft 310 slides backwards under the driving of the connecting shaft 320, the upper end of the moving shaft 310 moves in the linear chute 360, and the upper fixed block 3 is driven to move upwards/downwards. Since the motion track of the connecting shaft 320 is an arc moving backward, the motion track of the driving motion shaft 310 is also an arc, so that the horizontal straight chute 360 can be jacked up when the motion shaft 310 moves, and then the upper fixing block 3 is jacked up.

When the handle 350 is lifted upwards, the handle 350 rotates around the rotating shaft 340, at this time, the supporting rod 330 rotates along with the handle 350, the upper end of the supporting rod 330 is inclined backwards, so that the direction of the supporting rod 330 is changed from the vertical direction to the inclined direction, at this time, under the driving of the supporting rod 330, the connecting shaft 320 moves downwards in an arc track backwards, the connecting shaft 320 drives the lower end of the moving shaft 310 to move, so that the upper end of the moving shaft 310 moves in the linear chute 360, and the upper fixing block 3 is driven to move downwards. The arrangement is such that when the handle 350 is lifted upward, the support bar 330 rotates and tilts with the handle 350 so that the interval between the upper and lower fixing blocks 3 and 4 becomes smaller, and thus the upper fixing block 3 falls down and is compacted with the lower fixing block 4.
