Referring to fig. 1 to 3, a rolling pin 100 of the present application includes a hand-supporting portion 10, a pin body 20, and a rotating portion 30. Wherein the hand rest portion 10 is used for pressing by an operator. The shaft 20 includes an axially symmetric extruded section 21, and the extruded section 21 is used to extrude the dough into a flat shape, commonly referred to as "rolling skin". The axially symmetric extrusion section 21 is generally cylindrical and may be tapered at both ends to provide an overall shape similar to conventional pin-type rolling pins. And the pole body 20 can be formed by the extruded section 21, in other embodiments, only one section of the pole body 20 can be provided as the extruded section 21, and the extruded section 21 can be extruded to the dough without escaping the scope of the present invention. The rotating part 30 is connected between the hand-holding part 10 and the pole body 20, so that the hand-holding part 10 and the pole body 20 are connected in a rotating manner. It will be appreciated that the shaft body 20 is connected to the grip portion 10 for rotation about an axis 211 of the axially symmetric crush section 21.

Please refer to fig. 4. When the operator presses the hand rest 10 with force F, the force F generates a vertical component F1 and a horizontal component F2. The vertical component F1 may act on the dough to flatten the dough. The horizontal component F2 is due to the axially symmetrical configuration of the pinched portion 21 of the shaft 20, so that the F2 acting on the pinched portion 21 can rotate relative to the table top or any platform. That is, the palm of the operator can drive the stick body 20 to rotate back and forth under the action of the rotating portion 30 by pushing the hand supporting portion 10 to translate back and forth under the premise of keeping the palm in static contact with the hand supporting portion 10, so that the dough is extruded into a flat shape by the extruding section 21. Conventional rolling pins are generally cylindrical in shape, and the palm of the operator's hand needs to be repeatedly rubbed against the rolling pin. And this application clamp plate formula rolling pin 100 can provide the operation that the operator realized the rolling surface under the condition of static contact, and operator's palm has obtained effectual protection, can not produce discomfort or pain because of long-term repeated rolling friction, has improved operator's use and has experienced.

Referring to the embodiment of fig. 5, the rotating portion 30 includes a bearing 31, and an outer ring 311 and an inner ring 312 of the bearing 31 are fixedly connected to the hand-holding portion 10 and the pole body 20, respectively. It can be understood that the outer ring 311 and the inner ring 312 of the bearing 31 can rotate freely relative to each other, and the friction force is small. In the embodiment of fig. 5, the outer ring 311 of the bearing 31 is embedded in the shaft body 20, the grip portion 10 and the support 32 are fixedly connected with the inner ring 312 of the bearing 31 through a connector such as a screw or a rivet, the support 32 is also a part of the rotating portion 30, one end of the support 32 is fixedly connected with the grip portion 10, and the other end of the support 32 is fixedly connected with the inner ring 312, so that the effect that the rotating portion 30 is connected between the grip portion 10 and the shaft body 20, and the grip portion 10 is rotatably connected with the shaft body 20 is achieved.

Further, the pole body 20 comprises a first end 201 and a second end 202 opposite to each other along the axis 211 of the extruded section 21. The two bearings 31 and the two brackets 32 are provided, one bearing 31 and one bracket 32 are connected between the holding hand part 10 and the first end 201 in a matching manner, and the other bearing 31 and the other bracket 32 are connected between the holding hand part 10 and the second end 202 in a matching manner. Namely, the hand-supporting part 10 is bridged over the first end 201 and the second end 202 of the stick body 20 through the brackets 32 and the bearings 31 on both sides. Such an arrangement may maintain the integrity of the shaft 20 between the first end 201 and the second end 202 such that the extruded section 21 may be disposed between the first end 201 and the second end 202 throughout, maximizing the length and area of the extruded section 21.

Referring to the embodiment of fig. 6, a further improvement compared to fig. 5 is that there are two supporting portions 10 in fig. 6. The two hand supporting portions 10 are respectively connected with the bearing 31 and the bracket 32 near the first end 201, and connected with the bearing 31 and the bracket 32 near the second end 202. And a connecting part 11 fixedly connected is also arranged between the two supporting hand parts 10. The two retainer portions 10 are respectively disposed near the first end 201 and the second end 202, which facilitates the simultaneous contact of the two hands of the operator with the retainer portions 10 and the driving of the rolling motion of the rolling plate-type rolling pin 100 of the present application. The two hand-supporting portions 10 exert a greater force, and the two hand-supporting portions 10 spaced apart from each other allow the force exerted by the operator to act more evenly on the pole body 20. Connecting portion 11 is connected with two support hand portions 10 simultaneously, can guarantee to hold in the palm the atress of hand portion 10 more balanced, avoids holding in the palm hand portion 10 because the atress is uneven and produces the deformation.

Referring to the embodiment of fig. 7, the shaft body 20 is divided into a first section 221 and a second section 222 along the axis 211 of the pressing section 21. The shaft 20 further comprises a shaft 223 which extends into the first section 221 and/or the second section 222 and is adapted to fixedly connect the first section 221 to the second section 222. The mandrel 223 also passes through the inner race 312 of the bearing 31 and is fixedly connected to the inner race 312. The bearing 31 is located between the first section 221 and the second section 222. And after the mandrel 223 passes through the inner ring 312, it simultaneously passes through the inner parts of the first section 221 and the second section 222 in the embodiment of fig. 7, so that the fixed connection between the first section 221 and the second section 222 is realized. It will be appreciated that in order to prevent slippage between the core 223 and the first section 221 or the second section 222 and ensure that the pole body 20 rotates integrally and synchronously with the grip portion 10, the fit between the core 223 and the first section 221 and the second section 222 may be an interference fit, or a fixed pin may be driven into the core 223 between the first section 221 and the second section 222 as shown in fig. 7.

Referring to the embodiment of fig. 8, in fig. 8, the mandrel 223 is integrally formed with the first segment 221, and the end of the mandrel 223 far from the first segment 221 needs to first pass through the inner ring 312 and then pass through the inside of the second segment 222. The integrally formed mandrel 223 and the first segment 221 do not need to be provided with a connecting structure, so that the internal structure of the pressing plate type rolling pin 100 can be simplified.

It can be understood that in the embodiments of fig. 7 and 8, the pole body 20 is divided into the first section 221 and the second section 222, and the bearing 31 is arranged between the first section 221 and the second section 222, so that the hand supporting part 10 can be directly arranged in the middle of the pole body 20, and meanwhile, the force-bearing structure of the rotating part 30 is better, a longer cantilever-like structure in the embodiments of fig. 5 and 6 does not appear, and the palm strength of an operator can be directly converted into the rotating motion of the pole body 20. However, in the case of the plate rolling pin 100, the eccentric arrangement of the pressing segment 21 on the first segment 221 or the second segment 222 is not conducive to the exertion of force by the operator. For this reason, the pressing sections 21 are also disposed on the first section 221 and the second section 222, respectively, to achieve the skin rolling operation better. On the other hand, in the case that the engagement distance between the mandrel 223 and the hand-supporting portion 10 is long (fig. 7), two or more bearings 31 may be provided to stabilize the structure of the hand-supporting portion 10 and the pole 20. In the embodiment of fig. 7 and 8, the hand support part 10 is closer to the bracket 32, so that the hand support part 10 and the bracket 32 can be integrally arranged, and the structure is simplified.

With continued reference to the embodiment of fig. 8, the extruding sections 21 are respectively disposed on the first section 221 and the second section 222 such that the extruding sections 21 are divided into two sections by the bearing 31. During the rolling process, the operator inevitably places the dough at the position of the bearing 31 at the same time. In this case, the holder 32 is preferably formed in a cylindrical shape, and an inner hole (not shown) of the holder 32 surrounds the outer ring 311 of the bearing 31, and an outer diameter 322 of the holder 32 is equal to an outer diameter of the extruding section 21. That is, the bracket 32 surrounds the bearing 31 such that the outer surface of the bracket 32 is flush with the outer surface of the extruded section 31. When the dough is placed in the position of the bearing 31, the dough is in contact with the support 32 because of the wrapping of the support 32 around the bearing 31. And because the outer surface of the bracket 32 is flush with the outer surface of the extrusion section 21, the defects that the thickness of the dough sheet is uneven or step-shaped folds and the like are generated on the dough sheet because the bearing 31 is arranged in the middle in the process of extruding the dough sheet into the dough sheet can be avoided.

Referring back to fig. 1 to 3, in order to make the hand-supporting portion 10 fit more closely to the palm of the operator, the surface 12 of the hand-supporting portion 10 facing away from the pole body 20 is curved. Surface 12 can set up recess or arch, and recess or arch are the curved surface of smooth transition, and the palm of operator can be more laminating with surface 12 contact, the operator of being convenient for send forth effort, bigger area of contact also can improve operator's comfort level simultaneously.

On the other hand, it can be seen from fig. 5 to 8 that in order to reduce the friction between the bearing 31 and the pole body 20 or between the bearing 31 and the support 32, it is also necessary to provide a washer 40 between the bearing 31 and the support 32 and/or the pole body 20 in the direction in which the axis 211 of the grip segment 21 extends. The washer 40 on the one hand improves the finish between the bearing 31 and the shaft body 20 and/or the support 32 in the dynamic contact, and thus reduces friction. On the other hand, because the pole body 20 is mostly wooden, the support 32 also can adopt wooden, therefore the packing ring 40 can also adopt softer material preparation, avoids the wooden pole body 20 andor produces wearing and tearing because of the repeated friction between support 32 and the metallic bearing 31, increases the life of this application clamp plate formula rolling pin 100.

Example referring to fig. 9 and 6, the carriage 32 is also provided with two auxiliary wheels 321 at both ends along the axis 211. The rolling direction of the auxiliary wheel 321 is the same as that of the extrusion section 21, so that the support 32 can be supported in the rotational freedom degree along the axis 211, and the motion track of the hand supporting part 10 in the skin rolling process is stabilized. Meanwhile, the auxiliary wheel 321 can be used as a fulcrum, and the hand supporting part 10 forms a lever structure under the action of the fulcrum of the auxiliary wheel 321, so that the pressing force of the pressing section 21 can be smaller.

The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
