Referring to fig. 2 and 3, the mating section 41 of the screw in this embodiment at least includes a positioning hole section 411 and a transmission hole section 412, the mating shaft section at least includes a positioning shaft section 511 and a transmission shaft section 512, the positioning shaft section 511 is adapted to the positioning hole section 411, and the transmission shaft section 512 is adapted to the transmission hole section 412. The positioning shaft section 511 is matched with the positioning hole section 411 to prevent the screw rod 4 from shaking left and right in the working process; the transmission shaft section 512 is matched with the transmission hole section 412, so that the rotation of the motor output shaft 51 drives the screw rod 4 to rotate coaxially, namely, the transmission effect is realized.

Further, the transmission shaft section 512 is a regular polygon section with at least four sides, and the transmission hole section 412 adapted to the transmission shaft section 512 is a regular polygon section with at least four sides. In the present embodiment, the transmission shaft section 512 is a hexagonal shaft section, and the transmission hole section 412 adapted to the transmission shaft section 512 is a hexagonal shaft section. This ensures that the driveshaft section 512 and the bore section 412 can be mated together, i.e., the hexagonal shaft section can be inserted into the hexagonal bore section. Meanwhile, in this embodiment, the positioning shaft section 511 is further provided as a circular positioning shaft section, and the positioning hole section 411 adapted to the circular positioning shaft section is a circular positioning shaft section, so that the screw rod 4 is inserted into the motor output shaft 51 without considering the rotation angle, and the convenience of assembling the screw rod 4 is improved.

Because the screw rod 4 is matched with the motor output shaft 51 to realize positioning and fixing, a long matching section 41 of the screw rod 4 is required. Therefore, in this embodiment, referring to fig. 2, the mating section 41 of the screw is divided into three sections, wherein the positioning hole section 411 includes an upper positioning hole section 4112 and a lower positioning hole section 4111, and the mating section 41 of the screw is sequentially provided with the upper positioning hole section 4112, the transmission hole section 412, and the lower positioning hole section 4111 from the top end to the bottom end of the screw 4. That is to say, the middle of the fitting section 41 is a hexagonal shaft hole section, and the upper positioning hole section 4112 and the lower positioning hole section 4111 at both ends are both circular positioning shaft hole sections. Referring to fig. 3, the matching shaft segment of the motor output shaft 51 includes an upper positioning shaft segment 5112, a transmission shaft segment 512, and a lower positioning shaft segment 5111 from top to bottom, that is, the middle portion is a hexagonal shaft segment, and the upper positioning shaft segment 5112 and the lower positioning shaft segment 5111 at both ends are circular positioning shaft segments. Therefore, the transmission shaft section 512 can realize transmission of the screw rod 4 and limit the up-and-down movement of the screw rod 4, and the positioning shaft section 511 can realize positioning of the screw rod 4 and prevent the screw rod 4 from shaking left and right in the working process. Meanwhile, the arrangement is also beneficial to the balance of the upper side and the lower side of the screw rod 4, so that when the motor output shaft 51 drives the screw rod 4 to rotate, the transmission central point is at the central position of the screw rod matching section 41, and the load of the motor 5 is reduced.

In this embodiment, the length of the matching section 41 is set to be L1, the length of the screw rod 4 is set to be L, and by setting 1/3 to be L1/L to be 2/3, it is ensured that the screw rod 4 has a longer matching section 41, and the motor output shaft 51 can be inserted into the matching section 41 of the screw rod more, so that the positioning between the screw rod 4 and the motor output shaft 51 is more stable.

In this embodiment, the equivalent outer diameter of the screw rod 4 in the standing state is gradually reduced from top to bottom, and the equivalent outer diameter is a dotted line shown in fig. 2. That is, the equivalent shape of the screw 4 is a cone with a small upper end and a large lower end, which is beneficial to increasing the space between the upper end of the screw 4 and the side wall of the extrusion container 3 when the material falls into the screw 4. Meanwhile, the screw 421 is arranged outside the screw body 42, and the screw 421 at the upper end of the screw body 42 can push the material downwards, so that the material pushing efficiency is improved. It will be appreciated that the equivalent shape of the screw 4 may be a regular figure eight with a small upper end and a large lower end.

Referring to fig. 1, in the present embodiment, the container 3 is in the shape of a cone having an outer diameter gradually increasing from top to bottom. Therefore, the material is pushed to the screw rod 4 with the equivalent outer diameter size gradually reduced from top to bottom by the conical extrusion cylinder 3, and the material is pushed downwards by the spiral 421 at the upper end of the screw rod body 42, so that the screw rod 4 is always only subjected to vertical downward component force and cannot move upwards in the working process.

In addition, in this embodiment, still be equipped with spacing muscle 4121 on the inner wall of transmission hole section 412, spacing muscle 4121 is interference fit with transmission shaft section 512, is of value to realizing motor output shaft 51 to the high-efficient transmission of screw 4 like this, also can restrict reciprocating of screw 4 in the course of the work to a certain extent simultaneously, avoids screw 4 to reciprocate the displacement and lead to the instrument unstability to rock seriously and influence the effect of squeezing the juice in the course of the work greatly. The positioning shaft section 511 and the positioning hole section 411 are in clearance fit, so that the radial positioning of the motor output shaft 51 on the screw rod 4 is facilitated, and the screw rod 4 is prevented from shaking left and right in the working process. When the user is in dismouting screw rod 4, also need not to consider the location angle of screw rod cooperation section 41 and motor output shaft 51, make things convenient for screw rod 4 dismouting.

Because the axial positioning is realized only by matching the motor output shaft 51 with the screw rod 4, the problem that the screw rod 4 does not move up and down or shake left and right cannot be ensured. Therefore, in this embodiment, the screw rod 4 includes the matching section 41 and the screw rod body 42 from inside to outside, the top end surface of the screw rod body 42 has no matching portion for pivot matching, the screw rod 4 further includes a protruding edge for positioning the screw rod 4, the protruding edge is disposed in the lower region of the screw rod body 42, and the protruding edge is formed by extending the lower region of the screw rod body 42 to the outer edge, so that the extrusion cylinder 3 can be sleeved into the screw rod 4 and positioned in vertical matching with the protruding edge, and axial stability of the screw rod 4 is further ensured.

Referring to fig. 2 and 4, since the bottom end of the screw body 42 is circular in radial shape, the protruding edge is an annular boss 43, and the annular boss 43 and the screw body 42 are integrally formed, so as to improve the integrity of the annular boss 43 and the screw body 42, and facilitate the processing of the screw 4. The diameter of the annular boss 43 is the maximum diameter of the screw 4 so that the annular boss 43 can abut against the abutment portion 31. The top surface of the annular boss 43 is horizontally arranged, and the joint of the top surface of the annular boss 43 and the bottom end of the screw body 42 is of a bevel structure. Accordingly, the end surface of the container 3, which is abutted by the abutting portion 31 and the top surface of the annular boss 43, is also flat, so that when the abutting portion 31 is abutted by the top surface of the annular boss 43, the contact area is larger, and the abutment is more stable. The bevel structure is that the annular boss 43 and the screw body 42 are directly integrally formed because the equivalent shape of the screw 4 is a cone shape with a small upper part and a big lower part or a regular splayed shape, so that the process steps are simpler.

It can be understood that the joint between the top surface of the annular boss 43 and the bottom end of the screw body 42 is a circular arc surface. This makes the transition between the screw body 42 and the annular boss 43 more aesthetically pleasing, requiring only a single process step of rounding off after the integral molding step.

For the embodiment, the diameter of the outer edge of the annular boss 43 is D1, and the maximum diameter of the screw body 42 is D, 2mm ≦ (D1-D) ≦ 5 mm. That is, the wall thickness of the abutting portion of the annular boss 43 and the abutting portion 31 is d, which is equal to or greater than 2mm and less than 5mm, and the wall thickness of the abutting portion 31. This is so that the abutment 31 of the container 3 has a wall thickness which is strong enough to abut the upper surface of the annular ledge 43 but which is not so thick as to increase material costs and affect the aesthetics of the container 3. Meanwhile, the wall thickness of the abutting portion 31 can prevent the screw body 42 from shaking excessively in the working process, and can prevent the abutting portion 31 from deforming due to shaking and impact of the screw body 42 on the other hand. Preferably, in the present embodiment, the thickness d of the abutment 31 is 3 mm.

Furthermore, the diameter of the outer edge of the annular boss 43 is D1, the height of the annular boss 43 is h, h/D1 is more than or equal to 1/17 and less than or equal to 1/9mm, and h is more than or equal to 1mm and less than or equal to 5 mm. In this embodiment, the diameter D1 of the outer edge of the annular protrusion 43 is preferably 52mm, and the cover degree h of the annular protrusion 43 is preferably 4mm, i.e., h/D1 is 1/13. Therefore, the annular boss 43 is a relatively short annular boss 43 relative to the total length of the whole screw body 42, the center of gravity of the whole screw 4 is lowered, and the center of gravity of the screw 4 is more stable in the working process.

Furthermore, the extrusion container 3 is sleeved between the screw 4 and the annular boss 43 for abutting fixation, and the lower region of the extrusion container 3 is provided with an abutting part 31 abutting against the annular boss 43. When the abutting portion 31 and the screw rod 4 are assembled in place, the abutting portion 31 and the protruding edge are aligned up and down, and the abutting portion 31 in this embodiment is the bottom end surface of the extrusion container 3, that is, the bottom end surface of the extrusion container 3 is pressed against the upper surface of the annular boss 43, so as to axially position the screw rod 4, and the screw rod 4 cannot move up and down during the working process. In this embodiment, the abutting portion 31 is made of metal, and the rest of the container 3 is made of plastic.

It will be appreciated that the abutment 31 and the container 3 may both be of plastics material.

In this embodiment, the bottom is equipped with in the juice collecting cavity 2 with cyclic annular boss 43 complex recess 21, recess 21 is the ring shape, and the lower surface of cyclic annular boss 43 and the bottom surface butt of recess 21 to realize recess 21 to the radial positioning of cyclic annular boss 43, prevent promptly that screw rod 4 from rocking about. The outer edge of the annular boss 43 is in clearance fit with the annular groove 21, so that the annular boss 43 abrades the side wall of the annular groove 21 due to friction in the rotation process of the screw rod 4.

It can be seen from above that, when assembling the screw rod 4 to the motor output shaft 51, the annular boss 43 of the lower side of the screw rod body 42 is just installed in the annular groove 21 at the bottom of the juice collecting cavity 2, and then the extrusion cylinder 3 is sleeved into the screw rod 42, so that the butt part 31 and the annular boss 43 of the butt joint of the lower side of the extrusion cylinder 3 and the screw rod 4 are butted, the upper end of the extrusion cylinder 3 is buckled with the machine base 1, thereby tightly fixing the screw rod 4 between the lower surface of the butt part 31 of the extrusion cylinder 3 and the upper surface of the juice collecting cavity 2, and realizing the secondary axial positioning. The distance between the abutting part 31 and the upper surface of the annular boss 43 in the abutting state is less than 0.1mm, so that the screw rod 4 can rotate at a low speed, the screw rod 4 can only rock between 0.1mm up and down in the working process, and the juicing effect is ensured. Meanwhile, after the screw rod 4 is clamped, the screw rod 4 can be further prevented from shaking left and right in the working process.

In the present embodiment, the wall thickness of the abutting portion 31 in the horizontal direction is equal to the wall thickness of the annular projection 43 in the horizontal direction, and the outer diameter of the abutting portion 31 is equal to the outer diameter of the annular projection 43. When the abutting portion 31 abuts against the annular boss 43, the abutting portion 31 and the annular boss 43 are integrated better, and the cost is saved to a certain extent.

In addition, for the convenience of a user can easily dismantle the screw rod 4 upwards and clean the screw rod 4 after use, in the embodiment, referring to fig. 1, the sealing rubber ring 8 is arranged at the bottom of the juice collecting cavity 2, and the motor output shaft 51 penetrates out of the sealing rubber ring 8 and is directly inserted into the screw rod matching section 41. The motor output shaft 51 is in interference fit with the sealing rubber ring 8, a gap is reserved between the screw rod 4 and the sealing rubber ring 8, and the screw rod 4 is arranged above the sealing rubber ring 8. Therefore, the trouble that the user is difficult to upwards disassemble the screw rod 4 due to the fact that the matching section 41 of the screw rod needs to penetrate through the sealing rubber ring 8 to be matched with the motor output shaft 51 and the large friction force exists between the matching section 41 of the screw rod and the sealing rubber ring 8 is avoided.

It should be noted that the above-described structural changes to the present embodiment can be applied to other embodiments of the present invention.

Example two:

fig. 5 is a schematic structural diagram of a second embodiment of the present invention. In the embodiment, the length of the matching section is L1, the length of the screw 4 is L, and the screw 4 is ensured to have a longer matching section by setting 1/3 to be equal to or greater than L1/L to be equal to or less than 2/3. Referring to fig. 5, in the present embodiment, the matching section 41 of the screw is divided into two sections, which are a positioning hole section 411 and a transmission hole section 412 from the top end to the bottom end of the screw 4. That is, the positioning hole section 411 is provided at an upper side position of the screw inner fitting section 41. The positioning hole section 411 is a circular positioning shaft hole section, and the transmission hole section 412 is a hexagonal shaft hole section. The positioning shaft section 511 adapted to the positioning hole section 411 is a circular positioning shaft section, and the transmission shaft section 512 adapted to the transmission hole section 412 is a hexagonal shaft section. Therefore, the transmission shaft section 512 can realize transmission of the screw rod 4 and limit the up-and-down movement of the screw rod 4, and the positioning shaft section 511 can realize positioning of the screw rod 4 and prevent the screw rod 4 from shaking left and right in the working process. Meanwhile, the two-section screw rod matching section 41 and the two-section matching shaft section of the motor output shaft 51 simplify the matching section 41 and the matching shaft section, and the screw rod 4 is more convenient to mount on the motor output shaft 51.

It is understood that the bore section 412 may also be a square bore section, and the shaft section 512 adapted to the square bore section is a square shaft section.

It is understood that the hole section 412 may be a flower-shaped hole section, and the shaft section 512 adapted to the flower-shaped hole section is a flower-shaped shaft section.

The rest schemes and effects of the vertical juicer described in this embodiment are consistent with those of the embodiment, and are not described herein again.

Example three:

fig. 6 is a schematic structural diagram of a third embodiment of the present invention. In the embodiment, the length of the matching section is L1, the length of the screw 4 is L, and the screw 4 is ensured to have a longer matching section by setting 1/3 to be equal to or greater than L1/L to be equal to or less than 2/3. Referring to fig. 6, in the present embodiment, the mating section 41 of the screw is divided into two sections, which are a transmission hole section 412 and a positioning hole section 411 in sequence from the top end to the bottom end of the screw 4. That is, the transmission hole section 412 is provided at an upper position of the screw inner fitting section 41. The positioning hole section 411 is a circular positioning shaft hole section, and the transmission hole section 412 is a hexagonal shaft hole section. The positioning shaft section 511 adapted to the positioning hole section 411 is a circular positioning shaft section, and the transmission shaft section 512 adapted to the transmission hole section 412 is a hexagonal shaft section. Therefore, the transmission shaft section 512 can realize transmission of the screw rod 4 and limit the up-and-down movement of the screw rod 4, and the positioning shaft section 511 can realize positioning of the screw rod 4 and prevent the screw rod 4 from shaking left and right in the working process. Meanwhile, the two-section screw rod matching section 41 and the two-section matching shaft section of the motor output shaft 51 simplify the matching section 41 and the matching shaft section, and the screw rod 4 is more convenient to mount on the motor output shaft 51.

Example four:

fig. 7 to 8 are schematic structural views of a fourth embodiment of the present invention. In the embodiment, the length of the matching section is L1, the length of the screw 4 is L, and the screw 4 is ensured to have a longer matching section by setting 1/3 to be equal to or greater than L1/L to be equal to or less than 2/3. Preferably, L1 is more than or equal to 30mm, and L is more than or equal to 45mm and less than or equal to 90 mm.

Referring to fig. 7, in the present embodiment, the matching shaft segment of the motor output shaft 51 is divided into a plurality of segments, and the number of the segments is greater than three. Fig. 7 shows only the case of the mating shaft segments when the number of segments is 4. In this case, the total length of the mating shaft segment is a, and the lengths of the 4 mating shaft segments are a1, a2, A3 and a4, respectively, and a1+ a2+ A3+ a4 is a. It is understood that when the number of segments of the mating shaft segment is n, the total length of the mating shaft segment remains a, and the lengths of the n mating shaft segments are a1, a2, A3, and a4.... ann, and a1+ a2+ A3+ a4+.. + An ═ a, respectively.

Referring to fig. 8, in the present embodiment, the matching section 41 of the screw 4 is divided into a plurality of rudder sections, and the number of the sections is greater than 3. Similarly, the total length of the mating segment is L1, and the lengths of the 4-segment mating segment 41 are L1 ', L2', L3 ', L4', L1 '+ L2' + L3 '+ L4' ═ L1, respectively. It can be understood that when the number of the mating segment 41 is n, the total length of the mating segment 41 remains L1, and the lengths of the n mating segments 41 are L1 ', L2', L3 ', L4' · Ln ', L1' + L2 '+ L3' + L4 '+ · Ln' ═ L1, respectively.

It follows that it is necessary to ensure that the number of segments of the mating shaft segment must be identical to the number of segments of the mating segment 41, and that the mating shaft segment must also be adaptable to the mating segment 41. The positions of the transmission hole section 412 and the positioning hole section 411 in the matching section in the axial direction of the screw rod 4 can be freely arranged, but the positions of the transmission shaft section 512 and the positioning shaft section 511 in the matching shaft section in the axial direction of the motor output shaft 51 should be correspondingly adapted according to the specific positions of the transmission hole section 412 and the positioning hole section 411 in the matching section 41. In addition, the ratio of the total length of all the sections of the transmission hole sections 412 contained in the matching section 41 to the total length L1 of the matching section 41 is u, 1/3 is less than or equal to u is less than or equal to 2/3. Then, the ratio of the total length of the transmission shaft section 512 contained in the mating shaft section to the total length A of the mating shaft section is v, 1/3 ≦ v ≦ 2/3. Like this a plurality of transmission shaft sections 512 can realize the transmission to screw rod 4 and the up-and-down movement of restriction screw rod 4, and a plurality of location shaft section 511 can realize the location to screw rod 4 and prevent that screw rod 4 from rocking about in the course of the work.

The other schemes and effects of the vertical juicer described in this embodiment are the same as those of the first, second and third embodiments, and are not described herein again.

Example five:

fig. 9 is a schematic structural diagram of a fifth embodiment of the present invention. Referring to fig. 9, in this embodiment, the screw rod 4 includes, from inside to outside, a matching section 41 for driving the screw rod 4 and a screw rod body 42 for pressing the material, a top end surface of the screw rod body 42 does not have a matching portion for pivot matching, the screw rod 4 further includes a protruding edge for positioning the screw rod 4, the protruding edge is disposed on a lower region of the screw rod body 42, the protruding edge is formed by extending the lower region of the screw rod body 42 to an outer edge, and the protruding edge is an annular boss 43.

The bottom in the juice collecting cavity 2 is provided with a groove 21 matched with the annular boss 43 and the wrapping part 32, and the wrapping part 32 is arranged at the lower end of the extrusion cylinder 3. The groove 21 is circular, and the lower surface of the annular boss 43 is abutted to the bottom surface of the groove 21, so that the radial positioning of the groove 21 on the annular boss 43 is realized, and the screw rod 4 is prevented from shaking left and right. The outer edge of the annular boss 43 is in clearance fit with the annular groove 21, so that the annular boss 43 abrades the side wall of the annular groove 21 due to friction in the rotation process of the screw rod 4. The lower side of the extrusion cylinder 3 is provided with a contact part 31 which is pressed on the upper surface of the annular boss 43 of the screw rod 4.

In the present embodiment, referring to fig. 9, the abutting portion 31 is provided as an annular flange formed by inwardly protruding an inner wall of the lower side of the container 3. When the annular flange and the screw rod 4 are assembled in place, the screw rod 4 is assembled on the motor output shaft 51, the annular boss 43 on the lower side of the screw rod body 42 is just arranged at the bottom of the juice collecting cavity 2, and the extrusion cylinder 3 is sleeved into the screw rod 42, so that the annular flange and the annular boss 43 of the extrusion cylinder 3 are vertically abutted in the extrusion cylinder 3. At this time, the annular flange is pressed against the upper surface of the annular boss 43 of the screw 4, and the lower end of the container 3 is provided with a wrapping portion 32 for wrapping the side wall of the annular boss 43. The wrapping portion 32 belongs to the container 3, and the annular boss 43 can be positioned radially to prevent the screw 4 from shaking left and right. The annular groove 21 in this embodiment is used for simultaneously engaging the annular boss 43 and the wrapping portion 32, and to a certain extent, the annular groove 21 plays a role in simultaneously radially positioning the annular boss 43 and the wrapping portion 32.

It can be understood that the bottom of the juice collecting cavity 2 can be directly positioned radially on the annular boss 43 through the wrapping part 32 without arranging the circular groove 21, so that the screw rod 4 can not swing left and right.

Further, referring to fig. 10, the upper portion of the extrusion cylinder 3 is further provided with an upper cover 6 connected to the extrusion cylinder 3, the upper end of the upper cover 6 is provided with a feed inlet 7, the edge of the upper cover 6 is provided with an installation portion 61 for installing the extrusion cylinder 3, when the extrusion cylinder 3 is installed in place through the installation portion 61, the annular boss 43 of the screw rod 4 is tightly fixed between the lower surface of the abutting portion 31 of the extrusion cylinder 3 and the annular groove 21, so that the abutting portion 31 of the extrusion cylinder 3 is pressed against the annular boss 43, that is, the abutting portion 31 of the extrusion cylinder 3 axially positions the annular boss 43, and further, the axial positioning of the screw rod 4 is realized. In this embodiment, among the upper cover 6, the feed port 7, and the container 3, the upper cover 6 and the feed port 7 are integrated.

Referring to fig. 10, in the present embodiment, the mounting portion 61 includes a first mounting portion 611 and a second mounting portion 612, and fitted thereto are fitting members including the first fitting member 22 and the second fitting member 11. The first fitting portion 611 is engaged with a first engaging member 22 provided on the upper inner wall of the juice collecting chamber 2, and the second fitting portion 612 is engaged with a second engaging member 11 provided on the upper portion of the housing 1. The first mounting portion 611 is a slot structure at the edge of the upper cover 6, and the first fitting member 22 is a protrusion structure at the upper inner wall of the juice collecting cavity 2. The second mounting portion 612 is a protruding structure at the edge of the upper cover 6, and the second mating member is a slot structure at the upper part of the machine base 1. When the first mounting portion 611 and the first fitting member 22 are matched in place, and the second mounting portion 612 and the second fitting member 11 are also matched in place, the machine base 1 further compresses the upper cover 6, the upper cover 6 compresses the extrusion container 3 downwards, and the abutting portion of the extrusion container 3 axially compresses the annular boss 43, so that the boss cannot axially move, and the axial positioning of the screw rod 4 is further realized.

It can be understood that the upper cover 6, the feed inlet 7 and the extrusion cylinder 3 can also be formed integrally. Thus, when the first mounting portion 611 and the first fitting member 22 are matched in place, and the second mounting portion 612 and the second fitting member 11 are also matched in place, the machine base 1 further compresses the upper cover 6, and the abutting portions of the upper cover 6, the feed inlet 7 and the extrusion cylinder 3 are directly integrated to compress the annular boss 43 downwards, so that the boss cannot move axially, and the axial positioning of the screw rod 4 is further realized.

It can be understood that, among the upper cover 6, the feed port 7 and the extrusion cylinder 3, the upper cover 6 and the feed port 7 are integrated, but there is no second fitting member 11 on the machine base 1, and when there is no second mounting portion 612 on the edge of the upper cover 6, only depending on the first mounting portion 611 to fit with the first fitting member 22 in place, the upper cover 6 is fixed at the mounting position, so that the upper cover 6 presses the extrusion cylinder 3 downwards, and the abutting portion of the extrusion cylinder 3 axially compresses the annular boss 43, so that the boss cannot axially move, and further, the axial positioning of the screw rod 4 is realized.

It can be understood that the upper cover 6, the feed inlet 7 and the extrusion cylinder 3 can also be formed integrally, but the engine base 1 does not have the second fitting piece 11, and when the edge of the upper cover 6 does not have the second mounting portion 612, the abutting portions of the upper cover 6, the feed inlet 7 and the extrusion cylinder 3 directly and integrally press the annular boss 43 downwards, so that the boss cannot axially move, and the axial positioning of the screw rod 4 is further realized.

It will be appreciated that the first mounting portion 611 may be a raised formation on the edge of the upper cover 6, and the first fitting member 22 is a bayonet formation on the upper inner wall of the juice collecting chamber 2.

Therefore, when the screw rod 4 is installed in place by the installation part 61 and the corresponding fitting piece in addition to the unilateral positioning of the motor output shaft 51, the axial positioning of the screw rod 4 by the abutting part of the extrusion container 3 and the radial positioning of the screw rod 4 by the wrapping part 32 are realized, so that the stable operation state of the screw rod 4 in the working process is realized.
