The movable control member 9 includes a collar 21, which is movably sleeved on the surface of the connecting rod 14. The collar 21 moves on the surface of the connecting function to drive the movement of the bite rod 22. The inner wall of the collar 21 is fixed with a bite rod 22. The bite rod 22 is a tooth rod, which is similar in shape to teeth and is convenient for engagement with the bite groove 23. The positions of the two main screws 13 near the bite rod 22 and the end of the auxiliary adjusting screw 18 near the bite rod 22 are both provided with a bite groove 23. When needed, the rotating rod 11 is pulled to make the rotating rod 11 move between the transfer bottom plate 1 and the control seat 10. The positioning seat 10 moves and drives the collar 21 to move through the transmission gear 25 and the limit plate 26. The movement of the collar 21 drives the bite rod 22 to be inserted into the bite groove 23 on the main screw 13. The surface of the collar 21 is provided with outer ring teeth 24, and the outer ring teeth 24 are meshed with the transmission gear 25. Limit plates 26 are provided on both sides of the transmission gear 25. The limit plates 26 are located at both sides of the outer ring teeth 24. The rotating rod 11 is fixed on the surface of the limit plate 26, and then the anti-slip knob is rotated to drive the transmission gear 25 to rotate through the rotating rod 11. The rotation of the transmission gear 25 will drive the main screw 13 at the position of the bite groove 23 to rotate in the placement groove 3 through the collar 21 and the bite rod 22;

[0025] refer to Figure 2 and Figure 4 The movable control part 9 is arranged on the surface of the main adjusting screw part 6, the control positioning seat 10 is fixed inside the placement groove 3 and close to the position of the main adjusting screw, the rotating rod 11 moves on the control positioning seat 10, and guides and limits the rotating rod 11. One end of the rotating rod 11 is arranged on the control component 8, and the other end of the rotating rod 11 passes through the placement groove 3 and the transfer bottom plate 1 and extends to the outside of the transfer bottom plate 1. An anti-slip knob is arranged on the end face, and the rotating rod 11 is driven to rotate by manually turning the anti-slip knob block.

[0026] Example 2

[0027] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The placement groove 3 is provided with an integrated clamping assembly 4, which includes a main clamping assembly 5, and the main clamping assembly 5 includes a main adjusting screw member 6.

The connecting rod 14 is a round rod with a diameter smaller than the diameter of the main screw 13. In this way, the surface of the connecting rod 14 is sleeved with a secondary adjusting screw tube 18, and the diameter is only equal to the diameter of the main screw 13. In order to avoid the effect of thick auxiliary adjusting screw 18 on the transportation, the length of the entire main adjusting screw 6 matches the length of the transportation base plate 1, and the transportation base plate 1 is divided into two equal areas. At this time, the main adjusting screw 6 is located on the middle symmetric axis of the transportation base plate 1. This arrangement can make the clamped box stably placed on the transportation base plate 1 and the force is balanced. The divergent ends of the two main screws 13 are rotatably connected in the placement groove 3, and the main clamping plate is movably sleeved on the surface of the two main screws 13. The adjusting screw member 6 is rotatably connected to the inside of the placement groove 3.

The main clamping plate member includes a main clamping block 15 and a main clamping plate 16. The main clamping plate 16 is a square plate, and the surface of the main clamping plate 16 is provided with an anti-skid layer, which has a good anti-skid effect and further improves the stability of the box clamping. The main clamping block 15 is movably sleeved on the surface of the main screw 13, and the main clamping plate 16 is vertically fixed on the main clamping block When the main screw 13 rotates, the two main screws 13 will rotate to drive the two groups of main clamping blocks 15 to approach each other. The main clamping blocks 15 approach each other and drive the main clamping plates 16 to approach each other to clamp the two sides of boxes of different specifications (not shown) placed on the top of the transfer base plate 1, so that the box can be placed stably.

[0028] Example 3

[0029] refer to Figure 1-5The integrated clamping assembly 4 also includes a secondary adjustment clamping assembly 17, and the secondary adjustment clamping assembly 17 includes a secondary adjustment screw 18.

The secondary positioning seat 19 is fixed inside the placement groove 3. The adjusting screw is not positioned by the connecting rod 14, but is positioned by the secondary positioning seat 19, so that the secondary adjustment screw 18 is stabilized inside the placement groove 3 and rotates on the secondary positioning seat 19 and cannot move. In this way, the range of movement of the secondary clamping assembly 20 can be guaranteed. The surface of the secondary adjustment screw 18 is threadedly sleeved with the secondary clamping assembly 20. The secondary clamping assembly 20 includes a secondary movable block 27 and a secondary clamping block 28.

Adjustment rods 29 are rotatably arranged on both sides of the two groups of auxiliary movable blocks 27, and the other end of the adjustment rod 29 is rotatably connected to the auxiliary clamping block 28. The auxiliary clamping block 28 is close to the side position of the inner wall of the placement groove 3, and an auxiliary clamping plate 30 is vertically arranged on the auxiliary clamping block 28. After the main clamping plate 16 is in a stable position, it is necessary to push the rotating rod 11 , so that it drives the control component 8 to move and makes the bite rod 22 stuck in the bite groove 23 on the auxiliary adjusting screw 18, and then rotates the rotating rod 11, so that it drives the auxiliary adjusting screw 18 to rotate through the control component 8, and the rotation of the auxiliary adjusting screw 18 drives the main movable blocks to move away from each other, and the main movable blocks move away from each other, which will drive the two groups of auxiliary clamping blocks 28 to move closer to each other through the adjusting rod 29, and the two groups of auxiliary clamping blocks 28 move closer to each other, which will drive the auxiliary clamping plates 30 to move closer to each other and clamp them in the box body, so that the box body can be stably clamped;

[0030] The box can be removed by loosening the integrated clamping assembly 4, and different powder metallurgy products can be transported by replacing different boxes. The range of the main clamping plate 16 and the auxiliary clamping plate 30 can be controlled to facilitate clamping and positioning of boxes of different specifications. The transfer base plate 1 can also be used alone for rotation. The operation is very simple, which greatly improves the practicability and adaptability of the transfer device.

[0031] refer to Figure 1 A placing table 12 is provided on the top of the transfer bottom plate 1, and a travel groove is opened on the placing table 12 at the position corresponding to the main clamping plate and the auxiliary clamping plate 30.
