Description

Technical Field

[0001] This utility model relates to the field of cable conveying equipment technology, and in particular to a track assembly and a cable conveyor. Background Technology

[0002] Underground cable systems have become an important part of modern urban power grid structures due to their advantages such as not occupying ground resources, stable power transmission, and strong anti-interference capabilities.

[0003] Currently, cable laying mainly relies on cable conveyors for transportation. Typically, cable conveyors use two track assemblies to hold and transport the cable. However, as cable conveyors are used, the tracks on the track assemblies gradually loosen, affecting the transportation efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a track assembly that can improve the problem of track loosening in cable conveyors.

[0005] This utility model also proposes a cable conveyor having the above-mentioned track assembly.

[0006] A track assembly according to a first aspect of the present invention includes: a bracket; a drive shaft mechanism disposed on the bracket; a driven shaft mechanism disposed on the bracket and spaced apart from the drive shaft mechanism along a preset direction, the driven shaft mechanism being configured to move along the preset direction; a track, both ends of which are respectively sleeved on the drive shaft mechanism and the driven shaft mechanism; and a tension adjustment mechanism disposed on the bracket, the tension adjustment mechanism including an adjustment unit and an abutment block driven by the adjustment unit, the abutment block abutting against the side of the driven shaft mechanism near the drive shaft mechanism, the adjustment unit being used to drive the abutment block closer to or away from the drive shaft mechanism.

[0007] The track assembly according to the embodiments of the present utility model has at least the following beneficial effects:

[0008] In the track assembly of this invention, by adjusting the distance between the drive shaft mechanism and the driven shaft mechanism, the distance between them can be increased, making the track tighter and thus improving the stability of the transmission cable. Specifically, the adjustment unit can controllably drive the abutment block to move closer to or away from the drive shaft mechanism. When the abutment block moves away from the drive shaft mechanism, it pushes the driven shaft mechanism away from the drive shaft mechanism, thereby tightening the track. When the abutment block moves towards the drive shaft mechanism, the track loosens.

[0009] According to some embodiments of the present invention, the driven shaft mechanism includes a driven shaft movably disposed on the bracket along the preset direction, and a driven gear rotatably sleeved on the driven shaft, the track sleeved on the driven gear; wherein, the abutment block abuts against the side of the driven shaft near the drive shaft mechanism.

[0010] According to some embodiments of the present invention, the bracket includes an upper support plate, a lower support plate arranged at intervals and side by side below the upper support plate, and a connecting plate connecting the upper support plate and the lower support plate.

[0011] The upper and lower ends of the drive shaft mechanism are rotatably mounted on the upper support plate and the lower support plate, respectively; the upper and lower ends of the driven shaft mechanism are movably mounted on the upper support plate and the lower support plate, respectively; the track, the upper support plate, and the lower support plate together define the accommodating space;

[0012] The adjustment unit includes an adjustment rod and a transmission device that is pulsatorically connected to the adjustment rod. The transmission device is disposed within the accommodating space and connected to the abutting block. One end of the adjustment rod extends into the accommodating space and is pulsatorically connected to the transmission device, while the other end protrudes outside the accommodating space.

[0013] According to some embodiments of the present invention, the transmission device includes a third bevel gear, a fourth bevel gear, a threaded sleeve, and an adjusting screw;

[0014] The adjusting screw is parallel to the preset direction. The adjusting screw is located on the side of the abutment block away from the driven shaft mechanism, and the end of the adjusting screw is connected to the abutment block. The threaded sleeve is sleeved on the adjusting screw and is rotatably connected to the connecting plate. The fourth bevel gear is connected to the threaded sleeve and is coaxially arranged with the threaded sleeve. The third bevel gear meshes with the fourth bevel gear, and the axis of the third bevel gear is perpendicular to the axis of the fourth bevel gear. One end of the adjusting rod extends into the receiving space and passes through the third bevel gear.

[0015] According to some embodiments of the present invention, the driven shaft mechanism includes a driven shaft movably disposed on the bracket along the preset direction, and a driven gear rotatably sleeved on the driven shaft, the track being sleeved on the driven gear; wherein, the abutment block abuts against the side of the driven shaft near the drive shaft mechanism;

[0016] The side of the abutment block closest to the driven shaft is a concave positioning arc surface, which is adapted to the outer side wall of the driven shaft.

[0017] According to some embodiments of the present invention, the bracket is provided with a guide groove extending along the preset direction, and at least a portion of the driven shaft mechanism is slidably inserted into the guide groove.

[0018] According to some embodiments of the present invention, there are two guide grooves, which are arranged side by side and spaced apart along the axial direction of the driven shaft mechanism, and the two ends of the driven shaft mechanism are respectively inserted into the two guide grooves.

[0019] A cable conveyor according to a second aspect of the present invention includes: a base frame assembly; a support assembly disposed on the base frame assembly; and two track assemblies disposed side-by-side and spaced apart on the support assembly, wherein the spacing direction of the two track assemblies is perpendicular to the preset direction.

[0020] The cable conveyor according to the embodiments of the present utility model has at least the following beneficial effects:

[0021] In this cable conveyor, by adjusting the distance between the drive shaft mechanism and the driven shaft mechanism, the distance between them can be increased, making the track tighter and thus improving the stability of the transmitted cable. Specifically, the adjusting unit can controllably drive the abutment block to move closer to or further away from the drive shaft mechanism. When the abutment block moves away from the drive shaft mechanism, it pushes the driven shaft mechanism away from the drive shaft mechanism, thereby tightening the track. When the abutment block moves towards the drive shaft mechanism, the track loosens.

[0022] According to some embodiments of the present invention, the support assembly includes a support leg disposed on the base frame assembly and a bearing device disposed on the support leg. The bearing device includes two bearing mechanisms, which are arranged side by side and spaced apart, one on the left and one on the right.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] like Figure 1 , Figure 2 As shown, a cable conveyor provided in one embodiment of the present invention is used for conveying cables, and includes a base frame assembly 100, a support assembly 200 and two track assemblies 300.

[0048] like Figure 3 As shown, the chassis assembly 100 is configured to be pre-assembled into an independent module. It is understood that the chassis assembly 100 is assembled from various parts, and the chassis assembly 100 can be pre-assembled into an independent module.

[0049] The support assembly 200 is configured to be pre-assembled as an independent module. It is understood that the support assembly 200 is assembled from various parts and can be pre-assembled as an independent module.

[0050] Each track assembly 300 is configured to be pre-assembled as an independent module. Understandably, the track assembly 300 is assembled from a variety of parts and can be pre-assembled as an independent module.

[0051] like Figures 1 to 3 As shown, the support assembly 200 is detachably mounted on the base frame assembly 100, and two track assemblies 300 are detachably connected to the support assembly 200. The two track assemblies 300 are arranged side by side and spaced apart, and the cable can be clamped between the two track assemblies 300 and transported by the cable conveyor in operation.

[0052] In this cable conveyor, the base frame assembly 100, support assembly 200, and track assembly 300 are modularly designed. During transportation, these pre-assembled components can be transported separately and then reassembled on-site. In narrow areas such as tunnels and shafts, where the entire cable conveyor may be impassable, transporting the base frame assembly 100, support assembly 200, and track assembly 300 separately achieves the desired transport capability, improving the equipment's adaptability and flexibility in complex terrain and confined spaces. Furthermore, the track assembly 300, support assembly 200, and base frame assembly 100 are detachable, simplifying equipment maintenance and upgrades.

[0053] Combination Figure 1 and Figure 4 It is understood that a cable passage is defined between the two track assemblies 300, and the cable is placed in the cable passage and held by the two track assemblies 300; the underframe assembly 100 includes an underframe 110 and two cable limiting devices 120 disposed on the underframe 110. The two cable limiting devices 120 are spaced apart in the front-rear direction, and the two cable limiting devices 120 are respectively located on the front and rear sides of the cable passage. The cable limiting devices 120 are used to vertically limit the cable.

[0054] Understandably, the cable is held in the cable passage between the two track assemblies 300. The two tracks 340 can limit the cable in the lateral direction, while the cable limiting device 120 can limit the cable in the vertical direction, thereby reducing the risk of the cable moving vertically and coming off between the two track assemblies 300.

[0055] like Figure 4 As shown, specifically, the cable limiting device 120 includes a column 121 mounted on the base frame 110, a lower roller 122 mounted on the column 121, and an upper roller 123 mounted on the column 121. The upper roller 123 and the lower roller 122 are arranged side by side and spaced apart. One end of the upper roller 123 and the lower roller 122 are both facing left, and the other end is both facing right. The cable can be passed between the upper roller 123 and the lower roller 122. The upper roller 123 is used to limit the upper limit position of the cable, and the lower roller 122 is used to limit the lower limit position of the cable.

[0056] It should be noted that both the upper roller 123 and the lower roller 122 are rotatably mounted on the column 121, and both can rotate around their own central axis. Thus, when the cable is transported between the upper roller 123 and the lower roller 122, the cable, upon contact with the upper roller 123 and / or the lower roller 122, will cause the upper roller 123 and / or the lower roller 122 to rotate together, thereby reducing the friction experienced by the cable during transport.

[0057] Furthermore, the cable limiting device 120 also includes a first height adjustment mechanism 124 for adjusting the height of the lower roller 122 and a second height adjustment mechanism 125 for adjusting the height of the upper roller 123. Under the action of the first height adjustment mechanism 124 and the second height adjustment mechanism 125, the positions of the upper roller 123 and the lower roller 122 can be adjusted, thereby changing the upper limit position and the lower limit position of the cable.

[0058] like Figure 4 As shown, in some embodiments, the base frame 110 is provided with lifting rings 126, which also facilitates the operator to transport the entire base frame assembly 100.

[0059] Specifically, there are four lifting rings 126, which are respectively set at the four corners of the base frame 110.

[0060] like Figure 5 As shown, in some embodiments, the support assembly 200 includes a support leg 210 and a load-bearing device 220 disposed on the support leg 210, in combination with... Figure 1 and Figure 5 The support feet 210 are detachably mounted on the underframe assembly 100, and the bearing device 220 is used to support the two track assemblies 300.

[0061] Specifically, the base frame assembly 100 (base frame 110) is provided with a first mounting hole 111, and the bottom of the support leg 210 is provided with a second mounting hole 211 corresponding to the first mounting hole 111. The support leg 210 can be fixed to the base frame assembly 100 by means of bolts and nuts. At the same time, the bolts and nuts can be removed, thereby allowing the entire support assembly 200 to be detached from the base frame assembly 100.

[0062] Combination Figure 1 and, Figure 7 and Figure 8 The support device 220 includes two support mechanisms 221, which are arranged side by side and spaced apart. The two support mechanisms 221 respectively support two track assemblies 300. The two track assemblies 300 are respectively installed behind the two support mechanisms 221, and the two track assemblies 300 are also arranged side by side and on the left and right.

[0063] It should be noted that the track assembly 300 and the load-bearing mechanism 221 are detachably connected and can be separated, which facilitates the individual maintenance of the track assembly 300 and the load-bearing mechanism 221.

[0064] Combination Figure 7 and Figure 8 In some embodiments, the distance between the two support mechanisms 221 is adjustable, thereby adjusting the distance between the two track assemblies 300 to accommodate the transport of cables of different diameters, and also changing the clamping force of the track assembly 300 on the cable to ensure the reliability of cable transport.

[0065] Combination Figure 5 and Figure 8 Specifically, the support assembly 200 also includes a guide shaft 223 connected to the support foot 210. The guide shaft 223 extends in the left-right direction. Two support mechanisms 221 are sleeved on the guide shaft 223. One support mechanism 221 is fixed relative to the guide shaft 223, and the other support mechanism 221 can move relative to the guide shaft 223 along the axial direction (left-right direction) of the guide shaft 223.

[0066] Furthermore, one of the support mechanisms 221 is defined as a fixed support mechanism 221a, and the other support mechanism 221 is defined as a movable support mechanism 221b. The fixed support mechanism 221a is fixedly arranged relative to the guide shaft 223, and the movable support mechanism 221b is able to move relative to the guide shaft 223 along the axial direction of the guide shaft 223.

[0067] The support assembly 200 further includes an adaptive adjustment mechanism 222. The adaptive adjustment mechanism 222 includes a screw 2221 connected to the support foot 210 and arranged parallel to the guide shaft 223, a first nut 2222 sleeved on the screw 2221, a second nut 2223 sleeved on the screw 2221, and an elastic element 2224 with one end connected to the first nut 2222. The second nut 2223 and the first nut 2222 are spaced apart along the axial direction of the screw 2221. The fixed bearing mechanism 221a is fixedly connected to the second nut 2223. The elastic element 2224 is located on the side of the first nut 2222 closer to the second nut 2223. The movable bearing mechanism 221b is connected to the side of the elastic element 2224 away from the first nut 2222. The elastic element 2224 can apply a force to the movable bearing mechanism 221b toward the fixed bearing mechanism 221a.

[0068] Understandably, the two track assemblies 300 are respectively mounted on two support mechanisms 221. When no cable passes between the two track assemblies 300, the distance between the two support mechanisms 221 can be changed by adjusting the relative positions of the first nut 2222 and the second nut 2223, thereby adjusting the distance between the two track assemblies 300. When the cable is clamped between the two track assemblies 300 and transported, if the cable passing between the two track assemblies 300 bends in the left-right direction, the force exerted by the cable on the track assembly 300 will be transmitted to the elastic element 2224, causing the elastic element 2224 to contract. This causes the movable support mechanism 221b to move away from the fixed support mechanism 221a, thereby providing cushioning and preventing excessive pressure between the cable and the track assembly 300, which could damage the track assembly 300 and / or the cable.

[0069] Among them, the elastic element 2224 can be a spring, a sheet, or other elastic component.

[0070] Combination Figure 8 and Figure 9 Furthermore, the supporting mechanism 221 includes a support plate 2211 and a support block 2213 disposed below the support plate 2211. The support block 2213 is provided with a guide hole 22132 and a through hole 22133. The guide hole 22132 and the through hole 22133 are arranged in parallel, and the axis of the guide hole 22132 and the axis of the through hole 22133 both extend in the left and right direction. The guide hole 22132 is used for the guide shaft 223 to pass through, and the through hole 22133 is used for the screw 2221 to pass through. The support block 2213 has a hollow structure. For the fixed bearing mechanism 221a221, the second nut 2223 is located inside the support block 2213 and is fixedly connected to it. For the movable bearing mechanism 221b, the support block 2213 has two limiting walls 22131 spaced apart in the left-right direction. The first nut 2222 is located inside the support block 2213 and between the two limiting walls 22131. The first nut 2222 abuts against the limiting wall 22131 away from the fixed bearing mechanism 221a. One end of the elastic element 2224 abuts against the first nut 2222, and the other end abuts against the limiting wall 22131 close to the fixed bearing mechanism 221a. The elastic element 2224 is a spring, which is sleeved on the screw 2221. The screw 2221 can position the spring.

[0071] Combination Figure 5 and Figure 9 Each support mechanism 221 is also provided with a drive unit 2212 at the bottom of the support plate 2211, and the support plate 2211 is provided with mounting holes 22111 that pass through its upper and lower sides.

[0072] Specifically, the drive unit 2212 includes a drive motor 22121 and a transmission system 22122 that is connected to the drive motor 22121. The transmission system 22122 is provided with an insertion hole that is opposite to the assembly hole 22111.

[0073] More specifically, the transmission system 22122 includes a transmission rod 221221 that is connected to the motor at one end and a reduction gearbox 221222 that is connected to the other end of the transmission rod 221221. The reduction gearbox 221222 is provided with a socket.

[0074] Combination Figure 5 and Figure 6 The transmission components inside the gearbox 221222 include a first bevel gear 2212221 that is connected to the other end of the transmission rod 221221, and a second bevel gear 2212222 that meshes with the first bevel gear 2212221. The first bevel gear 2212221 is coaxially arranged with the transmission rod 221221, and the axis of the second bevel gear 2212222 is perpendicular to the axis of the first bevel gear 2212221. The second bevel gear 2212222 is coaxially arranged with and opposite to the insertion hole of the gearbox 221222, and the second bevel gear 2212222 is provided with a connecting hole 22122221 that is opposite to the insertion hole.

[0075] Combination Figure 10 and Figure 11 Each track assembly 300 includes a bracket 310, a drive shaft mechanism 320 disposed on the bracket 310, a driven shaft mechanism 330 disposed on the bracket 310 and spaced apart from the drive shaft mechanism 320 in the front-rear direction, and a track 340 wrapped around the drive shaft mechanism 320 and the driven shaft mechanism 330.

[0076] Specifically, the drive shaft mechanism 320 and the driven shaft mechanism 330 are arranged in parallel and side by side, and the axial directions of the drive shaft mechanism 320 and the driven shaft mechanism 330 are parallel to the vertical direction. The two ends of the track 340 are respectively wrapped around the drive shaft mechanism 320 and the driven shaft mechanism 330. When the drive shaft mechanism 320 rotates, it can drive the track 340 to run and rotate.

[0077] It should be noted that for the two track assemblies 300, the tracks 340 on the two track assemblies 300 are arranged side by side and spaced apart in the left and right direction, and the cable can be passed between the tracks 340 of the two track assemblies 300.

[0078] like Figure 11 and 12As shown, the drive shaft mechanism 320 includes a drive shaft 321 rotatably connected to the bracket 310 and a drive gear 322 fixedly sleeved outside the drive shaft 321. The driven shaft mechanism 330 includes a driven shaft 331 connected to the bracket 310 and a driven gear 332 rotatably sleeved outside the driven shaft 331. The two ends of the track 340 are respectively sleeved outside the drive gear 322 and the driven gear 332.

[0079] For each pair of corresponding support mechanisms 221 and track assemblies 300, the drive shaft mechanism 320 on the track assembly 300 passes through the mounting hole 22111 of the support mechanism 221 and is connected to the drive unit 2212 of the support mechanism 221 in a transmission manner.

[0080] Specifically, the drive shaft 321 passes through the mounting hole 22111 of the support plate 2211 into the insertion hole of the gearbox 221222, and then into the connecting hole 22122221 of the second bevel gear 2212222. The wall of the connecting hole 22122221 and the drive shaft 321 can be connected by a key. Specifically, a key can be provided on the wall of the connecting hole 22122221, and a keyway is provided on the outer wall of the drive shaft 321 for the key to pass through. After the drive shaft 321 passes through the connecting hole 22122221, the key can be inserted into the keyway, thereby enabling transmission between the drive shaft 321 and the second bevel gear 2212222.

[0081] It is understandable that when the drive motor 22121 is working, it can drive the first bevel gear 2212221 and the second bevel gear 2212222 to rotate through the transmission rod 221221, thereby driving the drive shaft mechanism 320 to rotate, thus making the track 340 work.

[0082] It is also understandable that during the process of installing the track assembly 300 to the load-bearing mechanism 221, the kinetic energy transfer between the drive unit 2212 and the drive shaft mechanism 320 can be realized after the drive shaft mechanism 320 is inserted into the mounting hole 22111. The installation is very convenient. In addition, the track assembly 300 and the load-bearing mechanism 221 can be fixed by bolting.

[0083] like Figure 11 and Figure 12 As shown, in some embodiments, the track assembly 300 further includes a tension adjustment mechanism 350 disposed on the bracket 310 and used to adjust the distance between the drive shaft mechanism 320 and the driven shaft mechanism 330.

[0084] Understandably, as the cable conveyor operates, the track 340 may become loose. By adjusting the distance between the drive shaft mechanism 320 and the driven shaft mechanism 330, the distance between them can be increased, making the track 340 tighter and thus improving the stability of the transmission cable.

[0085] In some embodiments, the driven shaft mechanism 330 is configured to move in a preset direction (front-back direction);

[0086] The tension adjustment mechanism 350 includes an adjustment unit 351 and an abutment block 352 driven by the adjustment unit 351. The abutment block 352 abuts against the side of the driven shaft mechanism 330 near the drive shaft mechanism 320. The adjustment unit 351 is used to drive the abutment block 352 to move closer to or away from the drive shaft mechanism 320.

[0087] Understandably, the adjustment unit 351 can controllably drive the abutment block 352 to move closer to or further away from the drive shaft mechanism 320. When the abutment block 352 moves away from the drive shaft mechanism 320, the abutment block 352 pushes the driven shaft mechanism 330 away from the drive shaft mechanism 320, thereby tightening the track 340. When the abutment block 352 moves toward the drive shaft mechanism 320, the track 340 will loosen.

[0088] Specifically, the abutment block 352 abuts against the side of the driven shaft 331 near the drive shaft mechanism 320.

[0089] like Figure 12 , Figure 13 As shown, in some embodiments, the bracket 310 includes an upper support plate 311, a lower support plate 312 disposed at intervals and side by side below the upper support plate 311, and a connecting plate 313 connecting the upper support plate 311 and the lower support plate 312.

[0090] The upper and lower ends of the drive shaft mechanism 320 are rotatably mounted on the upper support plate 311 and the lower support plate 312, respectively; the upper and lower ends of the driven shaft mechanism 330 are movable along a preset direction and are mounted on the upper support plate 311 and the lower support plate 312, respectively; the track 340, the upper support plate 311 and the lower support plate 312 together define the accommodating space.

[0091] The adjustment unit 351 includes an adjustment rod 3511 and a transmission device that is pulverically connected to the adjustment rod 3511. The transmission device is disposed within the receiving space and connected to the abutment block 352. One end of the adjustment rod 3511 extends into the receiving space and is pulverically connected to the transmission device, while the other end protrudes outside the receiving space. Thus, the operator can operate the adjustment rod 3511 to drive the abutment block 352 to move in a preset direction.

[0092] Specifically, the transmission device includes a third bevel gear 35121, a fourth bevel gear 35122, a threaded sleeve 35123, and an adjusting screw 35124. The axial direction of the adjusting screw 35124 is parallel to a preset direction (front-back direction). The adjusting screw 35124 is located on the side of the abutment block 352 away from the driven shaft mechanism 330, and the end of the adjusting screw 35124 is connected to the abutment block 352. The threaded sleeve 35123 is sleeved on the adjusting screw 35124 and is rotatably connected to the connecting plate 313. The fourth bevel gear 35122 is connected to the threaded sleeve 35123 and is coaxially arranged with the threaded sleeve 35123. The third bevel gear 35121 meshes with the fourth bevel gear 35122, and the axis of the third bevel gear 35121 is perpendicular to the axis of the fourth bevel gear 35122. One end of the adjusting rod 3511 extends into the receiving space and passes through the third bevel gear 35121.

[0093] Specifically, the threaded sleeve 35123 is fitted over the adjusting screw 35124 and supported by the connecting plate 313. The threaded sleeve 35123 is rotatably mounted on the connecting plate 313 via bearings. The threaded sleeve 35123 can rotate about its axis relative to the bracket 310. The fourth bevel gear 35122 is fitted over the threaded sleeve 35123, and the fourth bevel gear 35122 is connected to the threaded sleeve 35123 via a key. The fourth bevel gear 35122 and the threaded sleeve 35123 can rotate synchronously. The third bevel gear 35121 meshes with the fourth bevel gear 35122. The axis of 1 is perpendicular to the axis of the fourth bevel gear 35122. The adjusting rod 3511 is fixedly connected to the fourth bevel gear 35122 and is coaxial with the fourth bevel gear 35122. The adjusting rod 3511 is rotatably mounted on the bracket 310 through a bearing. The adjusting rod 3511 can be rotated, thereby driving the third bevel gear 35121 and the fourth bevel gear 35122 to rotate, thereby causing the threaded sleeve 35123 to rotate, which in turn drives the adjusting screw 35124 to move along the interval direction between the drive shaft mechanism 320 and the driven shaft mechanism 330, thereby adjusting the position of the abutment block 352.

[0094] Furthermore, the side of the abutment block 352 closest to the driven shaft 331 has a concave positioning arc surface, which is adapted to the outer wall of the driven shaft 331. This increases the contact area between the abutment block 352 and the driven shaft 331, improving the stability between them and reducing the risk of misalignment. Additionally, because the positioning arc surface is adapted to the outer wall of the driven shaft 331, the driven shaft 331 can only move in a preset direction (front-back direction) without rotating. Therefore, the abutment block 352 can restrict the adjustment screw 35124 from rotating with the threaded sleeve 35123. Thus, when the threaded sleeve 35123 rotates, the adjustment screw 35124 can only move axially in the preset direction.

[0095] Furthermore, the bracket 310 is provided with a guide groove 314 extending in a preset direction, and at least part of the driven shaft mechanism 330 is slidably inserted in the guide groove 314.

[0096] Specifically, there are two guide grooves 314. The two guide grooves 314 are arranged side by side and spaced apart along the axial direction of the driven shaft mechanism 330. The two ends of the driven shaft mechanism 330 are respectively inserted into the two guide grooves 314.

[0097] More specifically, one guide groove 314 is provided on the upper support plate 311, and the other guide groove 314 is provided on the lower support plate 312. The guide grooves 314 guide the movement of the driven shaft mechanism 330.
