Description

Technical Field

[0001] This utility model relates to the technical field of dehairing tools in slaughtering tools, and in particular to a handheld hair remover. Background Technology

[0002] Current handheld electric poultry plucking machines typically use two cones to rapidly rotate forward and backward, quickly removing fine feathers from poultry, which facilitates slaughtering and processing.

[0003] For example, Chinese utility model patent CN218790182U discloses a handheld electric poultry plucking machine and its steerable movable joint bearing seat, including a handle assembly, a motor assembly, a base, a bearing seat, a main cone rod, and a secondary cone rod. The handle assembly is mounted on the bearing seat via the base. The tail ends of the main cone rod and the secondary cone rod are rotatably connected to the bearing seat, and the cone ends of the main cone rod and the secondary cone rod can be brought close together. The motor assembly is located inside the handle assembly and is driven by the main cone rod and the secondary cone rod, and the motor assembly can drive the main cone rod and the secondary cone rod to rotate in opposite directions. The bearing seat includes a main bearing seat and a secondary bearing seat. The transverse I end of the main bearing seat is hinged to the transverse I end of the secondary bearing seat. This movable joint bearing seat structure allows the main bearing seat and the secondary bearing seat to be rotated by external force when the clamping force of the two cone rods weakens or is even lost, thereby clamping the cone ends of the two cone rods tightly together and ensuring the clamping force of the two cone rods.

[0004] However, the hair removal machine has a weak longitudinal limiting function. It is difficult to adjust the main cone rod and the auxiliary cone rod to the same plane during assembly. Moreover, after the hair roll spreads on the cone head, it is easy to cause misalignment, resulting in a reduction in hair removal effect. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a handheld hair removal tool that uses a plug-in structure to connect and limit the main cone rod and the secondary cone rod to be on the same plane.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A handheld hair removal device includes a motor assembly, a bearing housing, a main conical rod, and a secondary conical rod. The bearing housing is located at the front end of the motor assembly. The tail ends of the main conical rod and the secondary conical rod are rotatably connected to the bearing housing, and the conical ends of the main conical rod and the secondary conical rod can be brought into close contact. The motor assembly is driven by the main conical rod and the secondary conical rod, and the motor assembly can drive the main conical rod and the secondary conical rod to rotate in opposite directions. The bearing housing includes a main bearing housing and a secondary bearing housing. The main bearing housing plate is defined to have a transverse and a longitudinal direction, and the normal direction of the main bearing housing plate is the axial direction. The main bearing housing and the secondary bearing housing are respectively provided with clamping holes, and the clamping holes are... The hole extends axially, and a main tapered rod and a secondary tapered rod are connected to the hole via bearings. The main bearing seat and the secondary bearing seat are hinged together and can rotate around the hinge position in the transverse and axial planes so that the tapered ends of the main tapered rod and the secondary tapered rod arranged on them can approach and fit together or move away from each other. The main bearing seat and the secondary bearing seat are provided with at least one set of insert structures, which include a plug and a sleeve groove. The plug can be inserted into the sleeve groove when the main bearing seat and the secondary bearing seat rotate around the hinge position and approach each other, and the longitudinal width of the plug and the sleeve groove are matched.

[0008] The main bearing housing has external holes on both longitudinal end faces to allow for detachable bolt connection to the outer casing of the hair remover. The bearing housing is fixed to the outer casing using bolts or threads. The motor assembly is also fixed to the outer casing, and its drive shaft is connected to the main and auxiliary cone rods. The plug can be inserted into the sleeve groove when the main and auxiliary bearing housings rotate around the hinge position at a certain opening angle, which is 0°-20°, for example, 5° or 10°. The plug has a boss-like structure, and the sleeve groove has a rectangular or U-shaped groove structure.

[0009] Specifically, the insert structure includes insert structure I disposed in the middle of the main bearing housing and the secondary bearing housing, and / or, the insert structure includes insert structure II disposed at the front end of the main bearing housing and the secondary bearing housing. In one example, the insert structure includes insert structure I; in another example, the insert structure includes insert structure II; and in yet another example, the insert structure includes both insert structure I and insert structure II.

[0010] The socket structure I includes a plug I and a sleeve I; wherein the plug I is disposed on the transverse inner end face of the main bearing housing and the sleeve I is disposed on the transverse inner end face of the secondary bearing housing, or the plug I is disposed on the transverse inner end face of the secondary bearing housing and the sleeve I is disposed on the transverse inner end face of the main bearing housing; wherein the plug I has a boss-shaped structure and the sleeve I has a rectangular groove-shaped structure.

[0011] The socket structure II includes a plug II and a sleeve groove II; wherein, the sleeve groove II protrudes outward and is disposed on the transverse inner end face of the main bearing housing, and the plug II protrudes outward and is disposed on the front end face of the secondary bearing housing; wherein, the plug II has a boss-shaped structure, and the sleeve groove II has a U-shaped groove structure.

[0012] As described above, the main bearing housing and the secondary bearing housing are hinged together and can rotate around the hinge position in the lateral and axial planes, limiting their lateral and axial positions. Moreover, the main bearing housing and the secondary bearing housing are provided with at least one set of plug-in structures. When the main bearing housing and the secondary bearing housing rotate close to each other around the hinge position, the plug can be inserted into the sleeve groove, limiting their longitudinal position, so as to quickly assemble the main cone rod and the secondary cone rod in the same plane, thereby making their cone end faces parallel, so as to keep the main cone rod and the secondary cone rod in the same plane during operation and spacing adjustment, and improve the connection stability by using multi-directional limiting.

[0013] Based on the aforementioned solution, in an improved version, to address the issue of the two tapered rods' cone tips tightening and fitting together, the handheld hair remover also includes elastic elements. These elastic elements are mounted on the main bearing seat and the secondary bearing seat, and when assembled, they can compress the main bearing seat and the secondary bearing seat to rotate around the hinge position, bringing them closer together. For example, elastic elements are arranged on the longitudinal end faces of the main bearing seat and the secondary bearing seat, with their ends connected to the main bearing seat and the secondary bearing seat, respectively. Thus, the elastic force of springs and other elastic elements is used to tighten and fit the two tapered rods' cone tips together. As the cone tips thicken after being wrapped with hair, the spring force increases, ensuring the tightening effect of the two tapered rods. Furthermore, after removing the hair from the cone tips, the springs return to their initial clamping force, allowing the two tapered rods' cone tips to fit stably together.

[0014] Based on the aforementioned solution, in an improved version, to address the issue of adjusting the gap between the two tapered rods, the handheld hair remover further includes an adjusting component. This adjusting component comprises a bolt. The outer lateral end face of the main bearing seat or the secondary bearing seat has a through-hole for adjusting the distance. The bolt is threaded into the adjusting hole. When tightened, the bolt compresses the main bearing seat and the secondary bearing seat, causing them to rotate away from each other around the hinge position. Thus, by tightening the bolt on the main bearing seat or the secondary bearing seat to the corresponding locking position, it pushes outward from the opposite bearing seat laterally, adjusting the opening angle of the main bearing seat and the secondary bearing seat, so that the tapered surfaces of the two tapered rods are in contact or have a suitable gap.

[0015] Based on the aforementioned solution, in an improved version, to address the issue of the bolt intersecting with the tapered rod when centrally positioned, the adjusting component of the handheld hair remover further includes a through-tube. The inner lateral end face of the main bearing seat or secondary bearing seat has a concave groove, the position of which corresponds to the adjusting hole. The through-tube slides laterally connected to the groove. In the initial position, the lateral distance between the inner wall of the through-tube and the main or secondary tapered rod placed inside the through-tube is at its minimum value d1. When the bolt is tightened, it can compress the through-tube to move laterally relative to its initial position to its maximum value d2, forcing the main and secondary bearing seats to rotate away from each other around the hinge position, where d2 ≤ d1. The through-tube can be a cylinder, a regular polygonal cylinder, or a U-shaped groove. Thus, the bolt is pressed tightly against the through-tube, the through-tube extends laterally to the opposite bearing seat, and the tapered rod can be inserted into the through-tube and staggered, allowing for a centrally positioned adjusting structure to adjust the working position and avoid force imbalance.

[0016] Based on the aforementioned solution, in an improved version, to address the issue of rapid bearing assembly, the main bearing housing and the secondary bearing housing of the handheld hair remover are split into two parts along the longitudinal and axial planes passing through the center line of their clamping holes, respectively, and are connected by bolts for easy detachment. Thus, tapered bearings are placed on the left and right sides of the split structure, and then secured using bolt thread connections or bolted connections.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] This utility model discloses a handheld hair removal device, in which a main bearing seat and a secondary bearing seat are hinged together and can rotate around the hinge position in the lateral and axial planes, limiting their lateral and axial positions. Moreover, the main bearing seat and the secondary bearing seat are provided with at least one set of plug-in structures. When the main bearing seat and the secondary bearing seat rotate close to each other around the hinge position, the plug can be inserted into the sleeve groove, limiting its longitudinal position, so as to quickly assemble the main cone rod and the secondary cone rod in the same plane, which is conducive to adjusting so that the cone ends are parallel, so as to keep the main cone rod and the secondary cone rod in the same plane during operation and spacing adjustment. Multi-directional limiting improves the connection stability. Attached Figure Description

Detailed Implementation

[0022] Example 1

[0023] See Figure 9 Let a be the transverse direction, b be the longitudinal direction, and c be the axial direction. The length and width of the main bearing seat 4 plate are transverse (a) and longitudinal (b), respectively, and the normal thickness of the main bearing seat 4 plate is axial (c). It should be noted that this utility model is an improvement on the hinged bearing seat structure of an existing poultry plucking machine. For details regarding the outer shell, tapered rod, coupling 2, battery mechanism, motor, and control connections, please refer to existing poultry plucking machines, such as "A handheld electric poultry plucking machine and its steerable movable joint bearing seat, announcement number CN218790182U", and "A handheld poultry plucking machine, announcement number CN212035723U", etc.

[0024] See Figures 1-27 This embodiment 1 provides a handheld hair removal device, comprising a motor assembly 1, a bearing housing, a main cone rod 7, and a secondary cone rod 71. The bearing housing is located at the front end of the motor assembly 1. The tail ends of the main cone rod 7 and the secondary cone rod 71 are rotatably connected to the bearing housing, and the cone ends of the main cone rod 7 and the secondary cone rod 71 can be brought into close contact. The motor assembly 1 is driven by the main cone rod 7 and the secondary cone rod 71, and the motor assembly 1 can drive the main cone rod 7 and the secondary cone rod 71 to rotate in opposite directions. The bearing housing includes a main bearing housing 4 and a secondary bearing housing 41. The main bearing housing 4 is defined to have a transverse and a longitudinal direction, and the normal direction of the main bearing housing 4 is the axial direction. The main bearing housing 4 and the secondary bearing housing 41 are respectively provided with clamping holes 4. c and 41c, and the clamping holes are arranged to extend axially. The clamping holes 4c and 41c are respectively connected by bearings to the axially extending main cone rod 7 and secondary cone rod 71. The main bearing seat 4 and the secondary bearing seat 41 are hingedly connected and can rotate around the hinge position in the transverse and axial planes so that the cone ends of the main cone rod 7 and the secondary cone rod 71 arranged on them can approach and fit together or move away from each other. The main bearing seat 4 and the secondary bearing seat 41 are provided with at least one set of plug-in structures. The plug-in structure includes a plug and a sleeve groove. When the main bearing seat 4 and the secondary bearing seat 41 rotate around the hinge position and approach each other, the plug and the sleeve groove are matched in longitudinal width.

[0025] In order to fix the main bearing 8 and the motor assembly 1, in one example, a base connection such as that described in "A Handheld Electric Poultry Plucking Machine and Its Steering Movable Joint Bearing Seat, Publication No. CN218790182U" can be used. In another example, it can be directly connected through the outer shell, etc., which can be combined with other features to achieve the desired result. This application uses direct connection through the outer shell as an example. The longitudinal end faces of the main bearing seat 4 are respectively provided with external holes 4d so that it can be detachably connected to the outer shell of the plucking machine with bolts. The outer shell 100 includes a left part 100' and a right part 100', which are connected by existing bolts with threads or nuts. The main bearing seat 4 is fixed to the outer shell by bolt connection or thread connection. Similarly, the motor assembly 1 is fixed to the outer shell. The drive shaft of the motor assembly 1 is connected to the main cone rod 7 and the secondary cone rod 71.

[0026] The plug can be inserted into the sleeve groove when the main bearing housing 4 and the secondary bearing housing 41 rotate around the hinge position at a certain opening angle. This opening angle is 0°-20°, for example, 5° or 10°. This ensures that the main cone rod 7 and the secondary cone rod 71 have a limiting function when adjusting the gap within this opening angle range.

[0027] Furthermore, the plug may have a boss-like structure or a U-shaped protrusion structure with two bosses spaced apart, and the sleeve groove may have a rectangular groove or a U-shaped groove structure. The number of sleeve structures is illustrated using one or two as examples. Specifically, the sleeve structure includes sleeve structure I located in the middle of the main bearing housing 4 and the secondary bearing housing 41, and / or, sleeve structure II located at the front end of the main bearing housing 4 and the secondary bearing housing 41. Specifically, in one example, the sleeve structure includes sleeve structure I; in another example, it includes sleeve structure II; in yet another example, it includes both sleeve structure I and sleeve structure II, etc., all of which can be combined with other features. As shown in the figure, the simultaneous arrangement of sleeve structures I and II is used as an example for illustration.

[0028] The socket structure I includes a plug I and a sleeve I. In one example, the plug I is located on the inner lateral end face of the main bearing housing 4 and the sleeve I is located on the inner lateral end face of the secondary bearing housing 41; in another example, the plug I is located on the inner lateral end face of the secondary bearing housing 41 and the sleeve I is located on the inner lateral end face of the main bearing housing 4; etc., all of which can be combined with other features; as shown in the figure, one example is described here, and the plug I has a boss-like structure 4a and the sleeve I has a rectangular groove-like structure 41a.

[0029] The socket structure II includes a plug II and a sleeve groove II. Similarly, the socket structure I described above can be used; as shown in the figure, for better limiting effect, the sleeve groove II protrudes outward and is provided on the transverse inner end face of the main bearing seat 4, the plug II protrudes outward and is provided on the front end face of the secondary bearing seat 41, and the plug II has a boss 41b-shaped structure, and the sleeve groove II has a U-shaped groove 4b-shaped structure; etc., all of which can be combined with other features to achieve the desired effect.

[0030] The main bearing housing 44 and the auxiliary bearing housing 415 adopt a hinge structure, such as a hinge, or a hinge by setting left and right lifting lug slots or through holes and engaging a pin, or a hinge by using left and right lifting lug slots or through holes and engaging left and right pins, or a hinge by using left and right hanging shafts to wrap and clamp left and right blind holes, or an integrated pin hole and pin shaft hinge structure as described in "A handheld electric poultry plucking machine and its steerable movable joint bearing housing, announcement number CN218790182U", etc., which can all be combined with other features to achieve this. This application uses the left and right lifting lug through hole and pin shaft hinge structure as an example for explanation. Other existing hinge structures will not be described in detail here.

[0031] The main bearing housing 4 and the main tapered rod 7 are connected by at least one main bearing 8; this application uses two as an example. In one example, the diameter of the opening at both ends of the clamping hole can be increased to form bearing holes, and then the bearing can be embedded into the bearing hole axially. In another example, the main bearing housing 4 is a split structure consisting of a left part 4' and a right part 4" of the main bearing housing, which are divided along the longitudinal and axial plane passing through the center line of its clamping hole. It is connected by existing bolts with threaded holes or nuts, and has main assembly holes 4e and 4e" for bolting with main assembly bolts 4e', and is equipped with main fastening holes 4f and main fastening posts 4f' for fastening. Thus, in the split structure, two bearing holes are opened in the clamping hole to place the tapered rod bearing, and the bearing can be fixed by bolt thread connection or bolt connection. These can all be combined with other features to achieve the desired effect; this application uses a split structure as an example for explanation.

[0032] The secondary bearing housing 41 and the secondary tapered rod 71 are connected by at least one secondary bearing 81. This application uses two as an example for illustration. Similar to the structure of the main bearing housing 4 and the main tapered rod 7 described above, the secondary bearing housing 41 is a split structure divided into two parts along the longitudinal and axial planes passing through the center line of its clamping hole. It includes a left part 41' and a right part 41' of the secondary bearing housing, and it is detachably connected by bolts. It has secondary assembly holes 41e and 4e' for bolting with secondary assembly bolts, and is equipped with secondary snap-fit ​​holes 41f and secondary snap-fit ​​posts 41f' for fastening.

[0033] During assembly, the main bearing 8 and main gear 3 are installed on the main cone rod 7, and then the main bearing 8 is installed on the main bearing housing 4; then the auxiliary bearing 81 and auxiliary gear 31 are installed on the auxiliary cone rod 71, and then the auxiliary bearing 81 is installed on the auxiliary bearing housing 41; then the auxiliary bearing housing 41 is hinged to the main bearing housing 4 by aligning the hinge position of the pin shaft 441, and then the opening angle of the main bearing housing 4 and the auxiliary bearing housing 41 is tightened, and the connection limit is inserted through the plug sleeve structure; then the tail end of the main cone rod 7 is connected to the drive shaft of the motor set 1 through the coupling 2; then the motor set 1, the main bearing housing 4, and the auxiliary bearing housing 41 are installed on the left 100' or the right 100" of the outer casing, and the switch 101 and the power interface 102 are configured, and then the outer casing is assembled and bolted to fix the outer casing and the main bearing housing 4.

[0034] When in use, insert the power adapter (which is plugged into the AC220V mains socket) or battery mechanism 20, hold the tail end of the outer casing, turn on the switch 101 to make the motor run and drive the two cone rods (main cone rod and auxiliary cone rod) to rotate in opposite directions, so that the cone heads of the two cone rods are in contact and rotate. Then, put the conical suction end of the two cone heads in contact with the surface of the poultry. The hair is rolled in through the conical suction end of the two cone heads and then pulled out of the surface of the poultry, thus achieving hair removal. When stopping, first remove the handle away from the poultry, then turn off the switch to stop the motor, then put down the handle and unplug the adapter or battery mechanism.

[0035] As described above, the main bearing housing 4 and the secondary bearing housing 41 are hinged together and can rotate around the hinge position in the lateral and axial planes to form a movable joint bearing housing structure, which limits its lateral and axial positions. Moreover, the main bearing housing 4 and the secondary bearing housing 41 are provided with at least one set of plug-in structures. When the main bearing housing 4 and the secondary bearing housing 41 rotate around the hinge position and approach each other, the plug can be inserted into the sleeve groove to limit its longitudinal position, so as to quickly assemble the main cone rod 7 and the secondary cone rod 71 to be in the same plane, thereby making their cone end faces parallel, so as to keep the main cone rod 7 and the secondary cone rod 71 in the same plane during operation and adjustment of the spacing, and improve the connection stability by using multi-directional limiting.

[0036] Example 2

[0037] Based on Embodiment 1, Embodiment 2 has a tightening structure. In order to solve the problem of the clamping force of the two cone rods, a tension spring or a spring sheet can be used to provide a relatively stable clamping force. For details not covered, please refer to Embodiment 1 above.

[0038] See Figures 1-27 In order to solve the problem of the two cone heads of the hair removal device in this embodiment 2 being tightly fitted, the handheld hair removal device also includes an elastic element. The elastic element is installed on the main bearing seat 4 and the secondary bearing seat 41, and the elastic element can press the main bearing seat 4 and the secondary bearing seat 41 to rotate around the hinge position and tighten them when assembled.

[0039] In one example, an elastic element is used, with both ends connected to the main bearing housing 4 and its middle portion surrounding the outside of the secondary bearing housing 41; or, its two ends are connected to the secondary bearing housing 41 and its middle portion surrounds the outside of the main bearing housing 4; for example, the elastic element is a spring with spring segments at both ends, hooks at the ends, and an arc-shaped or rectangular extension connecting rod in the middle portion for surrounding arrangement. In another example, elastic elements are arranged on the longitudinal end faces of the main bearing housing 4 and the secondary bearing housing 41, with both ends of the elastic elements connected to the main bearing housing 4 and the secondary bearing housing 41, respectively. These can all be combined with other features, as shown in the figure. This application uses the arrangement of two springs 5 ​​as an example for illustration. The main bearing housing 44 and the secondary bearing housing 41 are respectively provided with spring holes 52 and 51 to hook the springs 5, and contraction holes are configured to accommodate the springs 5, utilizing the contraction force of the springs 5 ​​to achieve tightening.

[0040] In this way, the elastic force of the spring 5 and other elastic elements is used to tighten and fit the two cones together. After the cones are wrapped with hair, they become thicker and the elastic force of the spring 5 increases, which can ensure the tightening effect of the two cones. Moreover, after the hair is removed from the cones, the spring 5 will return to the initial clamping force, so that the two cones can fit together stably.

[0041] Example 3

[0042] Based on Examples 1 and 2, Example 3 has an adjustment structure. For details not covered, please refer to Examples 1 and 2 above.

[0043] See Figures 1-27 In this embodiment 3, to address the issue of adjusting the gap between the two tapered rods, the handheld hair remover also includes an adjusting component. This adjusting component includes a bolt 6. The outer lateral end face of the main bearing seat 4 or the secondary bearing seat 41 has a through-hole for adjusting the distance. The bolt 6 is threaded into the adjusting hole. When tightened, the bolt 6 can compress the main bearing seat 4 and the secondary bearing seat 41 to rotate away from each other around the hinge position. The bolt 6 can be directly connected using an adjusting bolt and a threaded hole; or, as shown in the figure, it can be connected using an adjusting bolt and a nut 61, with the nut 61 being defined by a positioning hole; etc., all of which can be combined with other features. To avoid misaligning the main or secondary tapered rods arranged on the same bearing seat, the adjusting hole and the clamping hole must be staggered to prevent them from connecting and causing the bolt to intersect and conflict with the main or secondary tapered rod.

[0044] In this way, the bolts 6 on the main bearing seat 4 or the secondary bearing seat 41 can be tightened to the corresponding locking and fixing position, so that they push out the opposite bearing seat in the lateral direction, and the opening angle of the main bearing seat 4 and the secondary bearing seat 41 can be adjusted so that the cone surfaces of the two cone rods are in contact or have a suitable gap.

[0045] Example 4

[0046] Based on Example 3, Example 4 adopts a centering adjustment structure. For details not covered, please refer to Example 3 above.

[0047] In order to solve the problem that the bolt 6, which is centrally located, will intersect and conflict with the cone rod, the adjustment component of the handheld hair remover in this embodiment 4 also includes a through-tube 62. The inner lateral end face of the main bearing seat 4 or the secondary bearing seat 41 is provided with a concave groove, and the position of the groove corresponds to the adjustment hole. The through-tube is slidably connected to the groove in the lateral direction. In the initial position, the lateral distance between the inner wall of the through-tube and the main cone rod 7 or the secondary cone rod 71 placed in the through-tube is the minimum value d1. When the bolt 6 is tightened, it can compress the through-tube to move laterally relative to the initial position to the maximum value d2, so as to force the main bearing seat 4 and the secondary bearing seat 41 to rotate away from each other around the hinge position, where d2≤d1, for example, d1 is 3cm and d2 is 2cm. The tube is a cylindrical tube, a regular polygonal tube, or a U-shaped groove, which is suitable for opening a sliding groove structure in the tube. As shown in the figure, taking a square tube as an example, a square sliding groove is opened. For example, the diameter of the main cone rod is 1cm, and the width of the inner wall of the square tube is 3cm. When the square tube is in the initial position, the main cone rod is inserted through its center. Then, when the square tube is in the initial position, d1 is 1cm. The maximum adjustable distance is d2≤1cm, which is 0.9cm, etc. When the adjusting bolt is tightened to d2=1cm, the inner wall of the square tube will contact the main cone rod.

[0048] In this way, the bolt 6 is pressed tightly against the through cylinder, the through cylinder is pushed out laterally to the bearing seat on the opposite side, and the tapered rod can be inserted into the through cylinder and staggered from each other. An adjustment structure can be set in the middle to adjust the position of action and avoid imbalance of force.

[0049] Example 5

[0050] This embodiment 5 provides a brief description of the bearing seat (clamp assembly cone head parallel device) of the hair removal device in embodiments 1-4 above. For detailed descriptions of its specific structural features and combination examples, please refer to the aforementioned embodiments.

[0051] See Figures 1-27This embodiment 5 provides a parallel device for the cone head of a handheld hair removal tool's chuck assembly, including a main bearing seat 4 and a secondary bearing seat 41. The main bearing seat 4 has a transverse and a longitudinal surface, with the normal direction of the main bearing seat 4 being axial. The main bearing seat 4 and the secondary bearing seat 41 are each provided with clamping holes, which extend axially to accommodate axially extending rotatable main cone rods 7 and 71. The main bearing seat 4 and the secondary bearing seat 41 are hinged together and can rotate around the hinge position in the transverse and axial planes, allowing the cone ends of the main cone rods 7 and 71 to approach or diverge. At least one set of insert structures is provided on the main bearing seat 4 and the secondary bearing seat 41, each including a plug and a groove.
