[0040] Specifically, the placement box 17 is placed through the placement groove 22, and the size of the placement groove 22 is adapted to that of the placement box 17 to improve the stability of the placement box 17. A plurality of holes 21 are formed at the bottom of the placement plate 3. When the motor shaft is heat-treated through the holes 21, the heat is more evenly distributed. At this time, connection columns 6 are provided at the four corners of the bottom of the placement plate 3, and insertion grooves 7 are formed at the bottoms of the connection columns 6. Correspondingly, insertion rods 15 are fixed at the four corners of the top of the moving bottom plate 1.

By rotating the fixing plate 10, the clamping groove 11 at the top is engaged with the clamping column 9 to achieve the connection strength between the placement plates 3. At the same time, when a single placement plate 3 is carried and stored, a storage groove 12 is formed in the middle of the fixing plate 10, and the storage groove 12 is engaged with the clamping column 9 of the placement plate 3 itself.

[0041] Refer to Figure 1 , Figure 2 and Figure 4, the fixing mechanism 2 includes a slideway 201. The bottom of the slideway 201 is fixedly connected to the top of the moving bottom plate 1. Electric push rods 202 are fixedly connected to both the front and rear sides of the slideway 201. One end of each of the two electric push rods 202 penetrates through the front and rear sides of the slideway 201 and is fixedly connected to a two-way connecting member 203.

Extrusion inclined plates 207 are slidably connected to the far sides of the multiple sliding members 204. Mounting seats 208 are fixedly connected to both the left and right sides of the top of the moving bottom plate 1. Sliding grooves 209 are formed in the front and rear sides of the tops of the two mounting seats 208. Extrusion blocks 210 are slidably connected to the inner walls of the multiple sliding grooves 209. Springs 211 are fixedly connected to the bottoms of the multiple extrusion blocks 210. The bottom ends of the multiple springs 211 are fixedly connected to the top of the moving bottom plate 1.

[0042] Specifically, a slideway 201 is fixedly installed on the top of the moving bottom plate 1. A sliding groove 215 is formed in the top of the slideway 201. The limiting rod 214 is slidably installed through the sliding groove 215. The bottom end of the limiting rod 214 is fixedly connected to the two-way connecting member 203. The electric push rods 202 on the front and rear sides of the slideway 201 are started to be squeezed inward, so that the two-way connecting member 203 contracts inward; at the same time, the two-way connecting member 203 and the sliding member 204 are rotatably installed through the crossed rotating plates 205. When the two-way connecting member 203 slides inward, the rotating plates 205 drive the sliding member 204 to move synchronously; at this time, the mutual rotation of the rotating plates 205 enables the sliding member 204 to drive the extrusion inclined plates 207 on both sides to expand outwards. The extrusion inclined plates 207 are inserted into the sliding grooves 209 on the mounting seats 208, so that the extrusion inclined plates 207 press the extrusion blocks 210 downward.

[0043] Refer to Figure 1 , Figure 3 and Figure 4Universal wheels 16 are installed at the four corners of the bottom of the mobile base plate 1, a control box 23 is fixedly connected to the right side of the top of the mobile base plate 1, and the front and rear sides of the placement box 17 are fixedly connected to the gusset plates 19, and the two gusset plates 19 are fixedly connected to the far sides thereof. A protrusion 20;

[0044] Specifically, the setting of the spring 211 provides a reverse restoring force. When the extrusion inclined plate 207 is separated from the extrusion block 210, the extrusion block 210 can automatically rebound, shrink the support column 212, and move with the universal wheel 16. Through the control box 23, the operating equipment on the entire bracket can be easily controlled.

[0045] Working principle: First, the motor shaft is accurately placed through the multiple positioning grooves 18 on the placement box 17. The positioning grooves 18 can avoid mutual collision and friction between the motor shafts, thereby improving the protection of the motor shaft; when stacking multiple placement plates 3, align the plug-in groove 7 at the bottom of the connecting column 6 with the top of the plug rod 4 and quickly insert it. A cross plate 5 is fixed on the outer wall of the plug rod 4 to enhance the overall structural strength of the bracket. The connection column 6 is combined with the plug rod 15 to effectively disperse the load and prevent the bracket from deforming under heavy pressure; the position and angle of the fixed plate 10 are adjusted, and the top card slot 11 is engaged with the card column 9 by rotating the fixed plate 10 to achieve the connection strength between the placement plates 3. When a single placement plate 3 is carried and stored, the fixed plate 10 is rotated to be level with the placement plate 3, and the storage slot 12 and the placement plate 3 are basically aligned. The clamping columns 9 of the body are engaged with each other to avoid the situation that the fixed plate 10 cannot be stored and affects the transportation process. After the motor shaft has completed the heat treatment, the bottom connecting column 6 of the placement plate 3 is inserted into the plug-in rod 15. After multiple placement plates 3 are stacked on the movable bottom plate 1, the electric push rod 202 is started to drive the two-way connecting member 203 to retract inward; at the same time, the sliding member 204 is driven to move synchronously through the rotating plate 205, so that the sliding member 204 drives the extrusion inclined plates 207 on both sides to expand to both sides, and the extrusion inclined plates 207 are inserted into the sliding grooves 209 on the mounting seat 208, so that the extrusion inclined plates 207 press the extrusion block 210 downward, and the spring 211 is contracted and extruded under the action of the extrusion block 210. At this time, the extrusion block 210 drives the supporting column 212 to support and fix the entire bracket, thereby improving the stability of the bracket.
