[0002] Automobiles are important means of transportation that are indispensable in people's lives, and their driving performance is closely related to people's life safety. To ensure the driving performance of automobiles, the components on the automobiles need to be calibrated regularly or as required after leaving the factory.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0064] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0065] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0066] Such as Figure 1-2As shown in the figure, a wheel hub clamping device 900 provided by one embodiment of the present invention includes a main body 100, a synchronization component 200, a locking module 300, and two jaw components 400. The synchronization component 200 is installed on the main body 100, the locking module 300 is fixedly installed on the main body 100, the two jaw components 400 are installed on the synchronization component 200, and the two jaw components 400 are located on both sides of the locking module 300. The clamping module 500 is installed on the main body 100. Among them, the locking module 300 can lock or release the synchronization component 200, and the jaw component 400 is used to be clamped to the wheel hub so that the wheel hub clamping device 900 adheres to the wheel hub.

[0067] When the locking module 300 is in the released state, move one of the jaw components 400 close to the locking module 300, and the synchronization component 200 drives the other jaw component 400 to synchronously approach the locking module 300 so that the locking module 300 is always located between the two jaw components 400; when the locking module 300 is in the locked state, the two jaw components 400 are fixed relative to the locking module 300, and the central axis of the locking module 300 coincides with the central axis of the wheel hub. Thus, when the wheel hub clamping device 900 is applied to four-wheel alignment of the wheels, it can be installed on the wheel hub through the two jaw components 400. During installation, the two jaw components 400 can be driven by the synchronization component 200 to move the same distance, ensuring that the locking module 300 is always located between the two jaw components 400, thereby ensuring that the central axis of the locking module 300 can coincide or approximately coincide with the central axis of the wheel hub.

[0068] It can be understood that the coincidence of the above two central axes described in this application does not require strict coincidence, and a certain error is allowed to exist, that is, the central axes can deviate by a certain angle, as long as it does not affect the calculation and calibration accuracy of the vehicle calibration equipment. Or, the two central axes can deviate by a certain angle, and this angle can be compensated by other means, such as the algorithm of calibration calculation. Here, the coincidence of the central axes described in this application includes the above various situations.

[0069] As Figure 3 As shown in the figure, for the main body 100, it includes a first substrate 110, a second substrate 120, and a connecting column 130. The first substrate 110 and the second substrate 120 are arranged at a preset distance apart, and the connecting column 130 connects the first substrate 110 and the second substrate 120. Among them, the first substrate 110 is provided with two first convex portions 111, and the two first convex portions 111 have a certain distance. The second substrate is provided with two second convex portions 121, and the two second convex portions 121 also have a certain distance.

[0070] It can be understood that the connecting column 130 can be connected to the first substrate 110 and the second substrate 120 through connecting parts such as screws, or can be connected by welding. Preferably, the connecting column 130 is connected to the first substrate 110 and the second substrate 120 through connecting parts such as screws, which is convenient for replacing connecting columns 130 of different lengths to adapt to wheels of different sizes. It can be understood that the length of the connecting column 130 can be adjusted according to user needs, and only needs to ensure that the two claw assemblies 400 can be connected to the wheel. It should be understood that the connecting column 130 is only for connecting the first substrate 110 and the second substrate 120, and its shape is not limited to a columnar shape. For example, it can be a cuboid shape or a cube shape.

[0071] For the synchronization assembly 200, it includes a first runner 210, a second runner 220 and a timing belt 230. The first runner 210 and the second runner 220 are respectively installed on both sides of the main body 100, and the first runner 210 and the second runner 220 can rotate relative to the main body 100. The timing belt 230 is sleeved on the first runner 210 and the second runner 220.

[0072] In this embodiment, the first runner 210 is installed between the two first convex portions 111 of the first substrate 110 through a rotating shaft. At this time, both ends of the rotating shaft are respectively connected to the two first convex portions 111, and the first runner 210 can rotate around the central axis of the rotating shaft. Similarly, the second runner 220 is installed between the two second convex portions 121 of the second substrate 120 through another rotating shaft, and the second runner 220 rotates around the other rotating shaft. Thus, when the timing belt 230 rotates, the first runner 210 and / or the second runner 220 rotate synchronously.

[0073] Of course, in some embodiments, the rotating shaft can be omitted. At this time, two opposite convex blocks (not shown in the figure) extend outward from the opposite sides of the two first convex portions 111. The first runner 210 is installed between the two opposite convex blocks, and the first runner 210 rotates around the central connection line of the two convex blocks. Similarly, the two second convex portions 121 can also be set in the same way.

[0074] Further, the outer sidewalls of the first runner 210 and the second runner 220 are provided with outwardly protruding teeth 211, the synchronous belt 230 is provided with inwardly protruding teeth 231, and the outwardly protruding teeth 211 mesh with the inwardly protruding teeth 231. Thus, the synchronous belt 230 can be in close contact with the first runner 210 and the second runner 220. When the synchronous belt 230 rotates, the first runner 210 and the second runner 220 also rotate synchronously. At this time, the outwardly protruding teeth 211 and the inwardly protruding teeth 231 mesh alternately, thereby effectively preventing the synchronous belt 230 from slipping and further improving the stability of the hub clamping device 900.

[0075] During installation, with the connection line between the centers of the first runner 210 and the second runner 220 as the central connection line, one claw assembly 400 is installed on the synchronous belt 230 on one side of the central connection line, and the other claw assembly 400 is installed on the synchronous belt 230 on the other side of the central connection line. Thus, when the synchronous belt 230 rotates, since the parts of the synchronous belt 230 on both sides of the central connection line move the same belt length and in opposite directions, it is ensured that the two claw assemblies 400 can approach or move away from the locking module 300 synchronously, and the two claw assemblies 400 move the same distance, making the locking module 300 located at the center of the two claw assemblies 400.

[0076] Please refer to Figure 2 、 Figures 4-6 For the locking module 300, it includes a mounting base 310, a bracket 320, a locking assembly 330, and an abutting block 340. The mounting base 310 is installed on the main body 100, the bracket 320 is installed on the abutting block 340, and the bracket 320 can move relative to the abutting block 340. The locking assembly 330 is installed on the mounting base 310, and the abutting block 340 is installed on the mounting base 310. Among them, the abutting block 340 includes a first abutting portion 341 and a second abutting portion 342, and the first abutting portion 341 is connected to the second abutting portion 342. Among them, the mounting base 310 is provided with a positioning hole 311, and the central axis of the positioning hole 311 is the central axis of the locking module 300.

[0077] When the locking assembly 330 is in the locked state, the abutting block 340 and the bracket 320 jointly clamp the synchronous belt 230, and the synchronous belt 230 is fixed; when the locking assembly 330 is in the loose state, the abutting block 340 does not abut against the synchronous belt 230, and the synchronous belt 230 can drive the two claw assemblies 400 to move.

[0078] Please refer to Figure 5, the bracket 320 includes a bottom plate 321, a top plate 322, and a guide post 323. The abutting block 340 is provided with a mounting hole 343. One end of the guide post 323 passes through the mounting hole 343 and is connected to the bottom plate 321, and the other end of the guide post 323 is connected to the top plate 322. Wherein, part of the synchronous belt 230 is located between the bottom plate 321 and the abutting block 340, and the guide post 323 can move relative to the abutting block 340.

[0079] The locking assembly 330 includes a main cam 331, a wrench 332, and a mounting shaft 333. The main cam 331 and the wrench 332 are both movably mounted on the mounting shaft 333. The main cam 331 is connected to the wrench 332. The mounting shaft 333 is mounted on the mounting seat 310, and the wrench 332 can rotate around the central axis of the mounting shaft 333.

[0080] Please combine Figure 6 with Figure 7 , during use, when the wrench 332 is gradually rotated in a preset direction, the main cam 331 pushes against the top plate 322 and moves away from the main body 100, so that the bottom plate 321 gradually approaches the first abutting portion 341 of the abutting block 340, thereby the bottom plate 321 and the abutting block 340 jointly clamp the synchronous belt 230.

[0081] It should be understood that the main cam 331 is an eccentric cam, which includes a top surface portion, a bottom surface portion, and a connecting portion. The connecting portion connects the bottom surface portion and the top surface portion. Wherein, the top surface portion is the part of the main cam 331 farthest from the center, the bottom surface portion is the part of the main cam 331 closest to the center, and during the process from the bottom surface portion along the connecting portion to the top surface portion, the distance between the outer wall of the main cam and the center of the main cam gradually increases.

[0082] During actual use, when the top plate 322 abuts against the bottom surface portion of the main cam 331, the wrench 332 is in the initial position. When the wrench 332 is gradually rotated in the preset direction, the top plate 322 abuts against different positions of the connecting portion of the main cam 331, and the top plate 322 is gradually pushed away from the main body 100, that is, the top plate 322 is gradually lifted, and drives the guide post 323 and the bottom plate 321 to move along the central axis of the mounting hole 343, so that the bottom plate 321 gradually approaches the abutting block 340. After the main cam 331 rotates a certain angle in the preset direction, the first abutting portion 341 of the bottom plate 321 and the abutting block 340 jointly clamp the synchronous belt 230. At this time, the locking assembly 330 is in the locked state, and the synchronous belt 230 is fixed and cannot move. When it is necessary to adjust the positions of the two jaw assemblies 400, the wrench 332 is rotated in the direction opposite to the preset direction, the top plate 322 gradually abuts against the bottom surface portion of the main cam 331, and the distance between the bottom plate 321 and the abutting block 340 gradually increases, so that the synchronous belt 230 is not clamped by the bottom plate 321 and the first abutting portion 341. At this time, the locking assembly 330 is in the loose state. Driving the synchronous belt 230 to rotate can drive the two jaw assemblies 400 to move to realize the adjustment of the positions of the two jaw assemblies 400. Among them, the preset direction is the counterclockwise direction with reference to the direction shown in the figure.

[0083] To better lock the synchronous belt 230, further, a convex tooth (not labeled) is provided on one end face of the bottom plate 321. When the first abutting portion 341 and the bottom plate 321 jointly clamp the synchronous belt 230, the convex tooth meshes with the inner convex tooth 231 of the synchronous belt 230, further enhancing the locking of the synchronous belt 230 by the locking assembly 330.

[0084] Please refer to again Figure 4 And Figure 5, in some embodiments, the locking assembly 330 further includes a secondary cam 334 rotatably mounted on the mounting shaft 333, and the secondary cam 334 is fixedly connected to the primary cam 331. When the wrench 332 is gradually rotated, the secondary cam 334 abuts against the second abutting portion 342 of the abutting block 340 and gradually drives the synchronous belt 230 to rotate. The synchronous belt 230 drives the two jaw assemblies 400 to move towards the locking module 330 so that the two jaw assemblies 400 clamp the wheel hub. It should be understood that in this embodiment, the structure of the secondary cam 334 is approximately the same as that of the primary cam 331, that is, the secondary cam 334 also includes a top surface portion, a bottom surface portion, and a connecting portion connecting the two. Among them, during the process of the wrench 332 rotating from the initial position to the position where the bottom plate 321 and the first abutting portion 341 jointly clamp the synchronous belt 230, the top surface portion of the secondary cam 334 does not abut against the second abutting portion 342. When the wrench 332 continues to rotate in the preset direction, the top surface portion of the secondary cam 334 abuts against the second abutting portion 342, and the abutting block 340 slightly moves in a direction away from the central axis of the mounting shaft 333 to drive the synchronous belt 230 to rotate, so that the two jaw assemblies 400 synchronously move slightly closer to the locking module 300 to provide a pre-tightening force to further clamp the wheel hub.

[0085] It can be understood that the slight movement of the abutting block 340 in a direction away from the central axis of the mounting shaft 333 can be that the connecting hole between the mounting seat 310 and the abutting block 340 is set as an oval hole, and the abutting block 340 can move slightly relative to the mounting seat 310. At this time, the abutting block 340 is directly connected to the mounting seat 310. Of course, the abutting block 340 and the mounting seat 310 can also be indirectly connected. The specific installation method is as follows:

[0086] Furthermore, the locking module 300 further includes a fixed block 350 and a sliding block 360. The fixed block 350 is fixedly mounted on the mounting seat 310. The sliding block 360 is mounted on the fixed block 350 and can slide along the fixed block 350. The abutting block is connected to the sliding block 360. Among them, the fixed block is provided with a slide rail (not labeled), and the sliding block 360 moves along the slide rail so that the abutting block 340 can move slightly in a direction away from the central axis of the mounting shaft 333.

[0087] In some embodiments, in addition to the above-described embodiments, the locking assembly 330 may also be a combination of a positioning bar (not shown in the figure) and a plug pin (not shown in the figure). The positioning bar is provided with a plurality of jacks. The positioning bar is installed on the mounting seat 310. When the bottom plate 321 is moved to clamp the synchronous belt 230 together with the abutting plate 340, at this time, the plug pin is inserted into the jack, and the plug pin abuts against the bottom plate 321, so as to lock the synchronous belt. Of course, in order to further strengthen the connection relationship between the plug pin and the positioning bar, the end of the plug pin is provided with a thread, and the jack is also correspondingly provided with a thread matching the plug pin, so that the plug pin is screwed into the jack.

[0088] It can be understood that the auxiliary calibration tool can be installed in the positioning hole 311. To strengthen the installation between the auxiliary calibration device and the wheel hub clamping device 900, the wheel hub clamping device 900 can be provided with a reinforcement structure for strengthening the installation of the auxiliary calibration device. For example, a protrusion that encloses the positioning hole 120 extends from the main body in a direction away from the locking module 300, and a fastening structure perpendicular to the central axis of the positioning hole 120 is provided on the protrusion. When the auxiliary calibration device is installed in the positioning hole 120, the auxiliary calibration device can be tightly abutted against the positioning hole 120 through the fastening device. Of course, the reinforcement structure can be other implementation manners; or the reinforcement structure is provided at the end of the auxiliary calibration device, or the installation between the wheel hub clamping device 900 and the auxiliary calibration device can be reinforced through an independent accessory. The specific implementation of the reinforcement structure is not limited in this application. Among them, the auxiliary calibration device can be a target with a calibration image, a laser for positioning the vehicle calibration equipment or cooperating with the vehicle calibration equipment, a reflective device, etc., which is not limited here.

[0089] Please refer to Figure 8 , for the jaw assembly 400, it includes a support seat 410, at least one extension arm 420 and a jaw 430. The support seat 410 is installed on the synchronous assembly 200. The extension arm 420 is connected to the support seat 410, and at least one jaw 430 is installed on one extension arm 420. The jaw 430 is used for clamping the wheel hub. In this embodiment, the support seat 410 is fixedly connected to the synchronous belt 230, which can be directly connected through a connecting member such as a screw, or can be realized by the combination of a connecting plate (not marked) and a connecting member to connect the support seat 410 and the synchronous belt 230. At this time, the connecting plate and the support seat 410 jointly clamp the synchronous belt 230 and are fixedly connected through a connecting member such as a screw.

[0090] The support base 410 includes a base 411, a first extension block 412, and a second extension block 413. The two ends of the base 411 are respectively connected to the first extension block 412 and the second extension block 413, and the first extension block 412 and the second extension block 413 are respectively connected to one of the outer extension arms 420. Among them, the first extension block 412 is connected to the synchronization component 200, and the base 411 is provided with a through hole 4111.

[0091] Please refer to Figure 5 , further, the wheel hub clamping device 900 further includes a clamping module 500. The clamping module 500 is installed on the main body 100, and the clamping module 500 is used for clamping the auxiliary calibration device. It should be understood that the auxiliary calibration device can be a target with a calibration image, a laser for positioning a vehicle calibration device or cooperating with a vehicle calibration device, a reflective device, etc., which are not limited herein. When the wheel hub clamping device 900 is attached to the wheel, the central axis of the clamping module 500 is aligned with the central axis of the wheel hub to ensure that the auxiliary calibration device is installed at the center of the wheel hub and ensure the accuracy of the calibration calculation of the calibration device for the vehicle.

[0092] The clamping module 500 includes a fixed seat 510 and a locking rod assembly 520. The fixed seat 510 is provided with a first through hole 511 and a second through hole 512. The first through hole 511 and the second through hole 512 are arranged in a cross manner, and the central axes of the first through hole 511 and the second through hole 512 are separated by a preset height. The first through hole 511 and the second through hole 512 are communicated. Among them, the first through hole 511 is used for installing the auxiliary calibration device, and the locking rod assembly 520 is installed in the second through hole 512, and the locking rod assembly 520 is used for locking the auxiliary calibration device. It should be noted here that the central axis of the first through hole 511 coincides with the central axis of the positioning hole 311 of the mounting seat 310.

[0093] It can be understood that the clamping module 500 is installed on the main body 100, which can be directly installed on the main body 100 or indirectly installed on the main body 100. When the clamping module 500 is indirectly installed on the main body 100, the fixed seat 510 is installed on the mounting seat 310, and the central axis of the positioning hole 311 coincides with the central axis of the first through hole 511.

[0094] The lock rod assembly 520 includes a screw rod 521, a first top block 522 and a second top block 523. The first top block 522 and the second top block 523 are both sleeved on the screw rod 521. The screw rod 521 is provided with a first external thread (not marked) and a second external thread (not marked). The helix directions of the first external thread and the second external thread are opposite. The first top block 522 is provided with a first internal thread (not marked) adapted to the first external thread, and the inner wall of the second top block 523 is provided with a second internal thread adapted to the second external thread. Wherein, the outer diameters of the first top block 522 and the second top block 523 respectively match the inner diameter of the second through hole 512. By rotating the screw rod 521, the first top block 522 and the second top block 523 approach each other, so that part of the first top block 522 and the second top block 523 are exposed from the first through hole 511 and abut against the auxiliary calibration device. In this embodiment, in order to prevent the first top block 522 from interfering with the second top block 523, the screw rod 521 partially protrudes to form a neck block 5211. The first top block 522 is located on one side of the neck block 5211, and the second top block 523 is located on the other side of the neck block 5211. The first external thread and the second external thread are also distributed with the neck block 5211 as the boundary. It should be understood that the diameter of the neck block 5211 needs to be smaller than the diameter of the second through hole 512 to facilitate the installation of the screw rod 521 in the second through hole 512. When the screw rod 521 is installed in the second through hole 512, the neck block 5211 is located at the intersection of the first through hole 511 and the second through hole 512.

[0095] With the above structure, the hub clamping device 900 can adjust the positions of the two jaw assemblies 400 through the synchronization assembly 200 so that the two jaw assemblies 400 adapt to the diameter of the hub. The hub clamping device 900 adheres to the hub, and then by rotating the wrench 332, the synchronous belt 230 is locked and the two jaw assemblies 400 clamp the hub. Since the central axis of the clamping module 500 coincides with the central axis of the locking module 300, at this time the central axis of the clamping module 500 is at the center of the two jaw assemblies 400. When the two jaw assemblies 400 are clamped to the hub, the central axis of the clamping module 500 coincides with the central axis of the hub.

[0096] Please refer to again Figure 1 And Figure 2, Further, the hub clamping device 900 further includes a guiding component 600. The guiding component 600 is installed on the main body 100, and two claw components 400 are installed on the guiding component 600, and the two claw components 400 are movable relative to the guiding component 600. In this embodiment, the guiding component 600 includes a first guide post 610 and a second guide post 620. The first guide post 610 and the second guide post 620 are arranged in parallel, and both ends of the first guide post 610 and the second guide post 620 are fixedly installed on the main body 100. The two claw components 400 are connected to the first guide post 610 and the second guide post 620.

[0097] Specifically, one end of the first guide post 610 is connected to the first substrate 110, and the other end of the first guide post 610 sequentially passes through the through holes 4111 of the two claw components 400 and then is connected to the second substrate 120. One end of the second guide post 620 is connected to the first substrate 110, and the other end of the second guide post 620 sequentially passes through the other through holes 4111 of the two claw components 400 and then is connected to the second substrate 120. Thus, when the synchronous belt 230 drives the two claw components 400 to move, the two claw components 400 approach or move away from the locking module 300 synchronously along the first guide post 610 and the second guide post 620. In this embodiment, the locking module 300 and the clamping module 500 are installed on the guiding component 600, that is, the locking module 300 and the clamping module 500 are installed on the first guide post 610 and the second guide post 620, and the mounting seat 310 and the fixed seat 510 jointly clamp the guiding component 600.

[0098] In some embodiments, in addition to the combination of the first guide post 610 and the second guide post 620 described above for the guiding component 600, the guiding component 600 can also be a combination of a guide rail and two sliders. At this time, both ends of the guide rail are respectively connected to the first substrate 110 and the second substrate 120, and one slider is installed at each end of the guide rail. One claw component 400 is connected to one slider.

[0099] It should be understood that the above-mentioned locking module 300 and the clamping module 500 are installed on the main body 100, which should be understood as the locking module 300 and the clamping module 500 are directly or indirectly installed on the main body. On the one hand, when the locking module 300 and the clamping module 500 are directly installed on the main body 100, the mounting seat 310 and the fixing seat 510 are both directly installed on the connecting column 130. On the other hand, when the locking module 300 and the clamping module 500 are indirectly installed on the main body 100, the mounting seat 310 and the fixing seat 510 are both installed on the guiding assembly 600, that is, installed on the first guide post 610 and the second guide post 620.

[0100] As Figure 1 shown, in some embodiments, the wheel hub clamping device 900 further includes a handle 700, and the handle 700 is installed on the claw assembly 400. When the handle 700 is pulled to drive one of the claw assemblies 400 to approach or move away from the locking module 300, the synchronization assembly 200 drives the other claw assembly 400 to synchronously approach or move away from the locking module 300. In this embodiment, the handle 700 is connected to the extension arm 420, which can be connected by a connecting member such as a screw or by welding.

[0101] During installation and use, the user can first pull the handles 700 on the two claw assemblies 400, and the synchronization assembly 200 drives the two claw assemblies 400 to move the same distance to ensure that the locking module 300 and the clamping module 500 are in the middle of the two claw assemblies 400. At the same time, by directly pulling the handle 700, the position of the claw assembly 400 can be quickly adjusted so that the opening amplitude of the two claw assemblies 400 relative to the locking module 300 is adapted to the outer dimension of the wheel hub, so that the claws 430 of the two claw assemblies 400 can be quickly clamped into the gap between the tire and the wheel hub of the wheel. For the specific installation effect, please refer to Figure 10As shown. When the jaw assembly 400 is clamped to the hub, rotate the wrench 332 so that the main cam 331 presses against the bracket 320 to move, so that the bottom plate 321 of the bracket 320 and the abutting block 340 jointly clamp the synchronous belt 230, thereby locking the synchronous assembly 200 to prevent the two jaw assemblies 400 from moving randomly. When the wrench 332 is rotated continuously, the secondary cam 334 abuts against the second abutting portion 342 of the abutting block 340, and the abutting block 340 drives the synchronous belt 230 to move slightly to provide a pre-tightening force for the two jaw assemblies 400 to clamp the hub. After the installation is completed, since the jaws 430 of the two jaw assemblies 400 are closely attached to the hub, the central position of the two jaw assemblies 400 at this time is the central position of the hub. Also, because the locking module 300 and the clamping module 500 are at the center of the two jaw assemblies 400, the central axes of the locking module 300 and the clamping module 500 coincide with the central axis of the hub at this time. When installing the auxiliary calibration tool, the central axis of the auxiliary calibration tool coincides with the central axis of the hub, improving the accuracy of four-wheel alignment.

[0102] The hub clamping device 900 provided by the embodiment of the present invention includes: a main body 100; a synchronous assembly 200 installed on the main body 100; a locking module 300 fixedly installed on the main body 100, and the locking module 300 can lock or release the synchronous assembly 200; two jaw assemblies 400 installed on the synchronous assembly 200, and the two jaw assemblies 40 are located on both sides of the locking module 300, and the jaw assembly 400 is used to be clamped to the hub; when the locking module 300 is in the released state, move one jaw assembly 400 close to the locking module 300, and the synchronous assembly 200 drives the other jaw assembly 400 to synchronously approach the locking module 300 so that the locking module 300 is always in the middle of the two jaw assemblies 400; when the locking module 300 is in the locked state, the two jaw assemblies 400 are fixed relative to the locking module 300, and the central axis of the locking module 300 coincides with the central axis of the hub. With the above structure, the hub clamping device 900 only needs to pull one jaw assembly 400 to move, and the synchronous assembly 200 will drive the other jaw assembly to move synchronously, without repeatedly turning the screw to adjust the position of the jaw assembly, which is more convenient and time-saving to use.

[0103] The above is only the embodiment of the present invention, and it does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
