[0040] The fixing device clamps the clamping member 100 to the outside of the fixed member via the connector 200, so as to transmit power to the fixed member.

[0041] However, during use, the connector 200 may fail or break. The broken connector 200 is difficult to remove because it is embedded in the clamping member 100, which makes maintenance inconvenient.

[0042] Specifically, when the hole used to insert the connector 200 is a blind hole, the part of the connector 200 that is broken and stuck in the blind hole is difficult to remove.

[0043] To address the technical problem of high maintenance difficulty in modifying the fixing device after the connector 200 breaks, the first embodiment of this application provides a fixing device. Please refer to... Figure 1 , Figure 2 and Figure 3 The fixing device has a clamping hole 110 and includes multiple clamping members 100 and connecting members 200. The multiple clamping members 100 are connected end to end to form the clamping hole 110. Each clamping member 100 has a through hole 120. Each clamping member 100 also has a groove 170, which surrounds the through hole 120 and communicates with it. In two adjacent clamping members 100, one has a groove 170 on the side facing away from the other. The connecting member 200 passes through the through holes 120 of two adjacent clamping members 100 and connects the two adjacent clamping members 100 respectively.

[0044] In some embodiments, the groove 170 is a countersunk groove of the through hole 120.

[0045] In some embodiments, the connector 200 is threadedly connected to at least one clamping member 100, that is, the through hole 120 of at least one clamping member 100 is a threaded hole 121.

[0046] In some embodiments, the connector 200 is a bolt; in some embodiments, in two adjacent clamping members 100, one has a through hole 120 that is a threaded hole 121, and the other has a through hole 120 that is not threaded, and the bolt head is connected to the clamping member 100 whose through hole 120 is not threaded.

[0047] It is understood that different parts of the connector 200 along the axial direction are respectively inserted into the through holes 120 of different clamping members 100 and respectively connected to the hole walls of the through holes 120 of different clamping members 100, so as to connect the different clamping members 100 together.

[0048] Firstly, in the above embodiment, since the connector 200 is inserted into the through hole 120, when the connector 200 breaks, the broken part of the connector 200 can be pushed out of the through hole 120 through the openings at both ends along the axial direction, reducing the maintenance difficulty of the fixing device after the connector 200 breaks.

[0049] Secondly, when the connector 200 is threadedly connected to the clamping member 100, after the broken connector 200 is pushed out of the threaded hole 121, the thread is damaged, and the connector 200 cannot connect with the hole wall of the through hole 120, thus limiting the clamping member 100 along the circumference of the connector 200. In the above embodiment, by providing a groove 170 facing away from the other in each of the two adjacent clamping members, a locking member 300 that can be threadedly connected to the connector 200 can be provided in the groove 170 after the thread is damaged. This allows at least two clamping members 100 to be clamped between the connector 200 and the locking member 300. Thus, even after the thread in the threaded hole 121 is damaged, the clamping member 100 can still be positioned by the connector 200 in the axial direction of the connector 200, and will not be scrapped due to damage to the internal thread, reducing the maintenance difficulty of the fixing device.

[0050] Thirdly, when all the holes 120 on the clamping members 100 for the connecting members 200 are through holes, the connecting member 200 can pass through either of two adjacent clamping members 100 before passing through the other when assembling the fixing device. This reduces the difficulty of using the fixing device and improves its ease of use.

[0051] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 The clamping member 100 has a clamping surface 130, an outer surface 140, and at least one first connecting surface 150. The clamping surface 130 is used to form a clamping hole 110. The outer surface 140 is disposed opposite to the clamping surface 130. The first connecting surface 150 is disposed between the clamping surface 130 and the outer surface 140, and is connected to the outer surface 140 and the first connecting surface 150 respectively. In two adjacent clamping members 100, at least one of the first connecting surfaces 150 faces at least one of the first connecting surfaces 150 of the other. The through hole 120 penetrates the first connecting surface 150 and the outer surface 140.

[0052] Specifically, the wall of the through hole 120 is spaced apart from the clamping surface 130 so that the connector 200 passing through the through hole 120 can be spaced apart from the fixed part in the clamping hole 110.

[0053] In the above embodiment, the through hole 120 penetrates the interconnected outer surface 140 and the first connecting surface 150, which can prevent the bolt from directly contacting the fixed part when the fixing device is working, reduce the possibility of the connector 200 breaking due to the relative displacement between the fixing device and the fixed part, thereby improving the reliability of the fixing device.

[0054] In some embodiments, please refer to Figure 4 and Figure 5The clamping member 100 has at least two first connecting surfaces 150, the clamping surface 130 is disposed between two adjacent first connecting surfaces 150 and connects the two first connecting surfaces 150 respectively, and the outer surface 140 is disposed between two adjacent first connecting surfaces 150 and connects the two first connecting surfaces 150 respectively.

[0055] In the above embodiments, since each first connecting surface 150 has a through hole 120, that is, each clamping member 100 has at least two connecting members 200 passing through and connected, and since the clamping surface 130 is located between the two first connecting surfaces 150, so that there are connecting members 200 on both sides of the fixed member, the fixed member can be clamped more evenly, the fixing effect of the fixing device is better, and the use effect of the fixing device is improved.

[0056] In some embodiments, at least two first connecting surfaces 150 connected to the clamping surface 130 are coplanar.

[0057] In the above embodiment, by setting the first connecting surfaces 150 on both sides of the clamping surface 130 to be coplanar, when two clamping members 100 are connected, the first connecting surfaces 150 of each of the two clamping members 100 can be arranged in parallel. This facilitates the connection of multiple clamping members 100 and also allows the first connecting surfaces 150 of the two clamping members 100 to fit tightly together when the fixing device is not in use, making it easy to store. In addition, the coplanarity of the two first connecting surfaces 150 of the same clamping member 100 also ensures that the clamping members 100 are symmetrical, provided that the first connecting surfaces 150 of adjacent clamping members 100 are parallel. When connecting adjacent clamping members 100, it is not necessary to distinguish the front and back of the clamping members 100, thereby reducing the difficulty of using the fixing device.

[0058] In some embodiments, please refer to Figure 4 The clamping surface 130 is recessed towards the outer surface 140 and forms a cylindrical part. The clamping surfaces 130 of the multiple clamping members 100 surround to form a clamping hole 110. The number of the multiple clamping members 100 is n. Along the axial direction of the clamping hole 110, the orthographic projection of the clamping surface 130 is an arc, and the central angle of the arc is α°, satisfying: α<360 / n.

[0059] It is understandable that since n is the number of items and there are multiple clamping parts (100), n ≥ 2, and n is an integer.

[0060] Specifically, the clamping member 100 further includes a second connecting surface 160, which is disposed between the clamping surface 130 and the outer surface 140, and connects the clamping surface 130 and the outer surface 140 respectively, and is connected to the first connecting surface 150. Along the axial direction of the clamping hole 110, the orthographic projection of the clamping surface 130 can be formed on the plane where the second connecting surface 160 is located.

[0061] In some embodiments, the fixing device includes only two clamping members 100, then α < 180°, that is, in this embodiment, the arc formed by the orthographic projection of the clamping surface 130 is not a complete semicircle.

[0062] In the above embodiment, by limiting the size of the central angle of the arc formed by the orthographic projection of the clamping surface 130, the orthographic projections of multiple clamping surfaces 130 cannot form a complete circle. This allows gaps to be formed between adjacent clamping members 100 when clamping the fixed member, thereby enabling the clamping member 100 to exert a greater clamping force on the fixed member for a longer period of time, thus improving the fixing effect of the fixing device on the fixed member.

[0063] In some embodiments, please refer to Figure 5 The outer surface 140 protrudes in the direction away from the clamping surface 130 and forms a cylindrical part. Along the axial direction of the clamping hole 110, the orthographic projection of the outer surface 140 is also an arc. The central angle of the arc formed by the orthographic projection of the outer surface 140 is β°, which satisfies: β < 360 / n.

[0064] Specifically, along the axial direction of the clamping hole 110, the orthographic projection of the outer surface 140 can be formed on the plane where the second connecting surface 160 is located.

[0065] In the above embodiment, by limiting the size of the central angle of the arc formed by the orthographic projection of the outer surface 140, the orthographic projections of the multiple clamping surfaces 130 cannot form a complete circle. This allows the multiple clamping members 100 to form gaps between adjacent clamping members 100 when clamping the fixed member, thereby enabling the clamping members 100 to exert a greater clamping force on the fixed member for a longer period of time, thus improving the fixing effect of the fixing device on the fixed member.

[0066] In some embodiments, please refer to Figure 1 , Figure 6 and Figure 7 In two adjacent clamping members 100, the first connecting surface 150 of one is spaced apart from the first connecting surface 150 of the other.

[0067] In the above embodiments, a gap can be formed between adjacent clamping members 100, thereby enabling the clamping member 100 to exert a greater clamping force on the fixed member for a longer period of time during clamping, thus improving the fixing effect of the fixing device on the fixed member.

[0068] In some embodiments, please refer to Figure 4 and Figure 7The clamping member 100 has a first groove wall 171 and a second groove wall 172. The first groove wall 171 is opposite to the first connecting surface 150, and the through hole 120 passes through the first groove wall 171. The second groove wall 172 is connected to the first groove wall 171 and forms a groove 170. The second groove wall 172 is connected to the outer surface 140. Among two adjacent clamping members 100, at least one of them has its first groove wall 171 connected to the outer surface 140.

[0069] In some embodiments, the first groove wall 171 of each of two adjacent clamping members 100 is connected to their respective outer surface 140; in some embodiments, only the first groove wall 171 of one of the two adjacent clamping members 100 is connected to the outer surface 140, while the first groove wall 171 of the other is spaced apart from the outer surface 140.

[0070] It is understandable that when the locking member 300 is placed in the groove 170, the locking member 300 fits against the first groove wall 171 to cooperate with the connector 200 and clamp at least two clamping members 100.

[0071] In the above embodiment, by connecting the first groove wall 171 to the outer surface 140, while the locking member 300 is in contact with the first groove wall 171, a portion of the locking member 300 can extend out of the groove 170. This arrangement allows for a wider range of choices for the specifications of the locking member 300, fewer restrictions, and reduces the difficulty of using the fixing device.

[0072] In some embodiments, please refer to Figure 4 In two adjacent clamping parts 100, at least one of them has a through hole 120 that is a threaded hole 121.

[0073] In some embodiments, among two adjacent clamping members 100, only one has a through hole 120 that is a threaded hole 121 (see Figure 6). The connecting member 200 is a bolt, which includes a head and a shank. The head can be connected to the first groove wall 171, and the shank has external threads to be threadedly connected to the internal threads in the threaded hole 121. Specifically, among two adjacent clamping members 100, the through hole 120 of the one connected to the head is a non-threaded hole 121, while the through hole 120 of the other is a bolt hole.

[0074] In some embodiments, in two adjacent clamping members 100, both have through holes 120 that are threaded holes 121.

[0075] In the above embodiment, by setting the threaded hole 121 so that when the thread in the threaded hole 121 can be used normally, the connection of two adjacent clamping parts 100 can be completed using only the connector 200, which can save the use of the locking part 300, reduce the number of parts of the fixing device, and reduce the difficulty of using the fixing device.

[0076] In some embodiments, please refer to Figure 7 The fixing device also includes a locking member 300, which is disposed in the groove 170. The connecting member 200 passes through the locking member 300, and two adjacent clamping members 100 are clamped between the portion of the connecting member 200 and the locking member 300.

[0077] In some embodiments, the connector 200 is a bolt and the locking member 300 is a nut.

[0078] In some embodiments, the size of the groove needs to be enlarged to facilitate the selection and installation of the locking element 300.

[0079] In the above embodiments, when the walls of the connector 200 and the through hole 120 cannot generate sufficient force to restrict the clamping member 100 from moving axially along the connector 200, for example when the internal thread inside the through hole 120 is damaged, the locking member 300 can connect with the connector 200 and clamp two adjacent clamping members 100 between the portion of the connector 200 and the locking member 300, thereby limiting the adjacent clamping members 100 along the axial direction of the connector 200 and improving the practical reliability of the fixing device.

[0080] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 5 The clamping member 100 has a relief groove 180, the relief groove 180 has a third groove wall 181, and the through hole 120 penetrates the third groove wall 181 to communicate with the relief groove 180; in two adjacent clamping members 100, the third groove wall 181 of one faces the third groove wall 181 of the other and surrounds and forms a relief hole 182.

[0081] In some embodiments, the clearance groove 180 is disposed on the first connecting surface 150; in some embodiments, the clearance hole 182 passes through two opposite second connecting surfaces 160 of the clamping member 100; in some embodiments, at least a portion of the connector 200 is exposed through the clearance hole 182, i.e., the connector 200 can be observed through the clearance hole 182.

[0082] In the above embodiment, by providing a clearance hole 182, at least a portion of the connector 200 can be exposed through the clearance hole 182, so that after the connector 200 fails, maintenance personnel can contact the connector 200 through the clearance hole 182 and process the connector 200 to facilitate the removal of the failed connector 200.

[0083] Specifically, in some embodiments, after the connector 200 breaks, the maintenance personnel can drill a hole in the side peripheral surface of the connector 200 through the through hole avoidance hole 182 and insert a tool into the connector 200 so that the connector 200 can rotate relative to the clamping member 100, thereby removing the connector 200.

[0084] In some embodiments, after the connector 200 breaks, the maintenance personnel can slot the cross-section of the connector 200 through the through-hole clearance hole 182 and use a tool to extend from the clearance hole 182 or the through hole 120 of another clamping member 100 into the slot of the cross-section to transmit torque so that the connector 200 can rotate relative to the clamping member 100, thereby removing the connector 200.

[0085] Accordingly, this application also provides a cutting device, including a fixing device as described in any of the above embodiments.

[0086] In some embodiments, the grooved wheel 400 passes through the clamping hole 110, and a plurality of clamping members 100 are arranged along the circumference of the grooved wheel 400 and clamp the grooved wheel 400.

[0087] The foregoing has provided a detailed description of a fixing device and a cutting device provided in the embodiments of this application. Specific examples have been used in this application to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application.
