[0027] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0028] In conjunction with Figure 1 ,Figure 2 , Figure 3 , Figure 4 and Figure 5 , including a speed reducer 1; a mounting assembly, the mounting assembly includes a connecting groove 2, a mounting block 201, a limiting chute 202 and a coupling 203. The connecting groove 2 is opened in the middle of one side of the speed reducer 1. A mounting block 201 is fixedly connected to one side of the connecting groove 2. Couplings 203 are arranged on the left and right parts of the middle of one side of the connecting groove 2. A connecting rod one 204 is fixedly connected to the side of the coupling 203 away from the connecting groove 2. A spline sleeve 205 is fixedly connected to the side of the connecting rod one 204 away from the coupling 203. A connecting ring one 206 is fixedly connected to the outer wall of the spline sleeve 205. Annular inclined grooves 207 are opened on the left and right parts of the side of the connecting ring one 206 away from the connecting groove 2. A slot 208 is penetrated and opened on one side of the two annular inclined grooves 207. When the extruder 209 is pushed forward so that the guide rod 214 abuts against the annular inclined groove 207, and by the force of pushing the extruder 209 forward, the guide rod 214 slides in the annular inclined groove 207. When the guide rod 214 slides in the annular inclined groove 207, it will drive the spline shaft 212 to rotate. An extruder 209 is arranged on one side of the speed reducer 1. Two conical screws 210 are penetrated and arranged inside the side of the extruder 209 close to the speed reducer 1, and the two conical screws 210 cooperate with each other. A connecting rod two 211 is fixedly connected to the side of the conical screw 210 away from the extruder 209. A spline shaft 212 is fixedly connected to the side of the connecting rod two 211 away from the conical screw 210, and the spline shaft 212 is meshed and connected with the spline sleeve 205. A connecting ring two 213 is fixedly connected to the outer wall of the connecting rod two 211. Guide rods 214 are fixedly connected to the upper and lower parts of the side of the connecting ring two 213 away from the extruder 209, and the guide rods 214 cooperate with the annular inclined groove 207 and the slot 208. When the guide rod 214 rotates into the slot 208, the spline shaft 212 will accurately align with the spline sleeve 205. When the extruder 209 is pushed forward, the spline shaft 212 is completely inserted into the spline sleeve 205.

[0029] Combined with Figure 3 , Figure 6 , Figure 7 and Figure 8, on both the left and right sides of one side of the connecting groove 2, there are rotatably connected double-headed threaded rods 3. On the top side of the connecting groove 2, there is fixedly connected a fixing plate 4, and the top of the double-headed threaded rod 3 penetrates through the fixing plate 4 and is rotatably connected. The tops of the two double-headed threaded rods 3 penetrate through the fixing plate 4 and are fixedly connected with synchronous pulleys 5. The outer wall of the synchronous pulley 5 is meshed with a synchronous belt 6, and the synchronous belt 6 is meshed with the synchronous pulley 5 at the other end. On the upper and lower parts of the outer wall of the double-headed threaded rod 3, there are threadedly connected pressing plates 7. By the meshing connection of the synchronous pulley 5 and the synchronous belt 6, the synchronous pulley 5 and the double-headed threaded rod 3 on the other side are also driven to rotate simultaneously. When the double-headed threaded rod 3 rotates, the two pressing plates 7 will approach each other, and then the coupling 203 is clamped by fitting the annular rubber groove 8 to the outer wall of the coupling 203. In the middle of the left side of the reducer 1, there is fixedly connected an output box 9, and the left double-headed threaded rod 3 penetrates through the output box 9 and is rotatably connected. In the middle of the outer wall of the double-headed threaded rod 3, there is fixedly connected a bevel gear one 10. In the middle of one side of the output box 9, there is penetrated and rotatably connected a rotating shaft 12. On one side of the rotating shaft 12, there is fixedly connected a bevel gear two 11, and the bevel gear two 11 is meshed with the bevel gear one 10. On the side of the rotating shaft 12 away from the bevel gear two 11, there is fixedly connected a turning handle 13. Rotating the turning handle 13 clockwise makes the rotating shaft 12 and the bevel gear two 11 rotate, making the bevel gear two 11 meshed with the bevel gear one 10 to make the double-headed threaded rod 3 rotate. When the double-headed threaded rod 3 rotates, it will drive the synchronous pulley 5 to rotate.

[0030] Combined with Figure 6 , in the middle of the opposite sides of the pressing plates 7, there are respectively provided annular rubber grooves 8, and the annular rubber grooves 8 cooperate with the coupling 203. By fitting the annular rubber grooves 8 to the outer wall of the coupling 203, the coupling 203 is clamped to prevent the coupling 203 from rotating during installation.

[0031] Combined with Figure 1 , on the upper and lower parts of one side of the reducer 1 close to the connecting groove 2, there are respectively fixedly connected connecting plates two 15. On both ends of the outer wall of the extruder 209, there are respectively fixedly connected connecting plates one 14, and one of the connecting plates one 14 is threadedly connected with the connecting plate two 15. When the extruder 209 is pushed forward so that the spline shaft 212 is completely inserted into the spline sleeve 205, the connecting plate one 14 and the connecting plate two 15 are installed by threaded connection.

[0032] Combined with Figure 5 , on the lower part of the outer wall of the extruder 209, there is fixedly connected a support seat 16. At the four corners of the bottom of the support seat 16, there are respectively installed pulleys 17, which are used to support the extruder 209. At the same time, the extruder 209 can be moved through the pulleys 17.

[0033] Combined with Figure 1 , on one side of the lower part of the reducer 1, there is provided an input end 18, and the input end 18 can be connected to a motor.

[0034] Working principle: During installation, first move the support base 16 and the extruder 209 closer to the speed reducer 1 through the pulley 17. At the same time, rotate the handle 13 clockwise to make the rotating shaft 12 and the second bevel gear 11 rotate, so that the second bevel gear 11 meshes with the first bevel gear 10 to make the bidirectional threaded rod 3 rotate. When the bidirectional threaded rod 3 rotates, it will drive the synchronous wheel 5 to rotate. Through the meshing connection of the synchronous wheel 5 and the synchronous belt 6, the synchronous wheel 5 and the bidirectional threaded rod 3 on the other side will also rotate simultaneously. When the bidirectional threaded rod 3 rotates, the two extrusion plates 7 will move closer to each other, and then fit the annular rubber groove 8 to the outer wall of the coupling 203 to clamp the coupling 203 to prevent the coupling 203 from rotating during installation;

[0035] Then, push the extruder 209 forward so that the guide rod 214 abuts against the annular inclined groove 207. With the force of pushing the extruder 209 forward, the guide rod 214 slides in the annular inclined groove 207. When the guide rod 214 slides in the annular inclined groove 207, it will drive the spline shaft 212 to rotate. When the guide rod 214 rotates into the slot 208, the spline shaft 212 will accurately align with the spline sleeve 205. Then push the extruder 209 forward to insert the spline shaft 212 completely into the spline sleeve 205. At the same time, install the first connecting plate 14 and the second connecting plate 15 through threaded connection, which can avoid the problem that the meshing of the conical twin screws and the speed reducer may not be ideal, resulting in reduced efficiency or increased noise, and may also cause excessive wear or failure;

[0036] After the connection between the spline shaft 212 and the spline sleeve 205 is completed, rotate the handle 13 counterclockwise to make the rotating shaft 12 and the second bevel gear 11 rotate, so that the second bevel gear 11 meshes with the first bevel gear 10 to make the bidirectional threaded rod 3 rotate. When the bidirectional threaded rod 3 rotates, the two extrusion plates 7 will move away from each other to release the clamping of the coupling 203.
