The use is divided into two forms, the first bearing seat or the motor base is shown in fig. 8, two fixing holes B are arranged in parallel, taking the bearing seat as an example, when the form is used, a fixing plate at the bottom of the bearing seat is placed on the bottom plate 2, and then the main lock and the auxiliary lock of the first form are selected, as shown in fig. 1-3, the main lock end: the nut 8-1 of the adjusting pull rod 8 reserves enough margin for the moving block 5 to move, the position of the moving block 5 is adjusted according to the distance between the two fixing holes B, then the moving inserting barrel 6 and the locking screw 7 are inserted into the fixing holes B together, at the moment, the distance of 1-2 cm can be reserved between the nut 8-1 and the screw cap 7-1 to ensure that the adjusting pull rod 8 pulls the locking screw 7 to rotate for reserving margin, and certainly, the nut 8-1 can be directly attached to the screw cap without reserving margin, so that only the rotation amplitude of the locking screw 7 is small, the locking effect is slightly poor relative to the slightly larger form of the rotation amplitude, and the locking is not influenced basically; then the front hook 13 falls down to hook the connecting disc 9;

the auxiliary locking end is used for adjusting the auxiliary moving block 11-2 to enable the auxiliary moving block to correspond to the fixing hole B on the other side, then the fixing column 11-3 with a proper size is inserted into the auxiliary moving block 11-2 to enable the auxiliary square cap 11-3-1 to be just clamped into the square groove, then the auxiliary locking turntable 12-1 is rotated to enable the auxiliary locking rod 12 to rotate and keep a primary tensile force on the auxiliary adjusting base plate 11 (the mode that the auxiliary locking rod 12 rotates and pulls the auxiliary adjusting base plate 11 belongs to the prior art, and the locking rod 10 can be referred to);

then, the locking turntable 10-1 is rotated, so that the locking rod 10 pulls the adjusting pull rod 8, the adjusting pull rod 8 pulls the locking screw 7 to rotate, the locking screw 7 rotates, meanwhile, the movable insertion cylinder 6 cannot rotate because the square cap 6-1 is clamped in the square groove 5-1, the locking screw 7 is in threaded fit with the movable insertion cylinder 6, the locking screw 7 moves downwards and pushes the V-shaped elastic sheet 6-2, and the V-shaped elastic sheet 6-2 pushes the inner side wall of the fixed hole B, so that the probability that the movable insertion cylinder 6 is separated from the fixed hole B is reduced; and (4) finishing temporary locking and positioning until the locking rod 10 tightens the adjusting pull rod 8.

The second bearing seat or motor base is shown in fig. 9, and has a connecting rib C or other separating member in the middle, or takes the bearing seat as an example, when this form is used, the fixing plate at the bottom of the bearing seat is placed on the bottom plate 2, and then the main lock and the auxiliary lock of the second form (shown in fig. 6 and 7) are selected, and the main lock end: the nut 8-1 of the adjusting pull rod 8 reserves enough margin for the vertical plate 5-2 to move, the position of the moving block 5 is adjusted according to the distance between the two fixing holes B, then the moving inserting barrel 6 and the locking screw 7 are inserted into the fixing holes B together, at the moment, the distance of 1-2 cm can be reserved between the nut 8-1 and the screw cap 7-1 to reserve margin for the adjusting pull rod 8 to pull the locking screw 7 to rotate, and certainly, the nut can be directly attached without reserving margin, so that only the rotation amplitude of the locking screw 7 is small, the locking effect is slightly poor compared with the slightly larger form of the rotation amplitude, but the locking is not influenced basically; then the front hook 13 falls down to hook the connecting disc 9; in the form, the two adjusting pull rods 8 are in a V shape, and the middle connecting rib plate C is avoided, so that the adjustment is carried out adaptively according to the field condition.

The auxiliary locking end adjusts the auxiliary vertical plate 11-2-1 to enable the auxiliary vertical plate to correspond to the fixing hole B on the other side, then the fixing column 11-3 with the proper size is inserted into the auxiliary vertical plate 11-2-1 to enable the auxiliary square cap 11-3-1 to be just clamped into the square groove, and then the auxiliary locking turntable 12-1 is rotated to enable the auxiliary locking rod 12 to rotate and keep a primary tensile force on the auxiliary adjusting base plate 11;

then, the locking turntable 10-1 is rotated, so that the locking rod 10 pulls the adjusting pull rod 8, the adjusting pull rod 8 pulls the locking screw 7 to rotate, the locking screw 7 rotates, meanwhile, the movable insertion cylinder 6 cannot rotate because the square cap 6-1 is clamped in the square groove 5-1, the locking screw 7 is in threaded fit with the movable insertion cylinder 6, the locking screw 7 moves downwards and pushes the V-shaped elastic sheet 6-2, and the V-shaped elastic sheet 6-2 pushes the inner side wall of the fixed hole B, so that the probability that the movable insertion cylinder 6 is separated from the fixed hole B is reduced; and (4) finishing temporary locking and positioning until the locking rod 10 tightens the adjusting pull rod 8.

After all equipment locking is accomplished, can be pressed close to a plurality of feeder branchs and put, when needing to move, can move the position of feeder branchs at any time. The invention has convenient and fast use, high safety and stability and is beneficial to popularization and application.
