The rotating wheel 420 includes an inner cylinder 421, an outer cylinder 422, and a connecting plate 423, and both ends of the connecting plate 423 are connected to an outer wall of the inner cylinder 421 and an inner wall of the outer cylinder 422, respectively. The inner cylinder 421 is sleeved on the mounting shaft 4112, so that the rotating wheel 420 can rotate around the mounting shaft 4112. Wherein, both ends of the inner cylinder 421 extend outward to form a protruding portion 4211. One side surface of the wheel 420 abuts against the boss 4114 to support the wheel 420, and at the same time, the contact area between the wheel 420 and the box 411 is reduced to reduce the friction between the box 411 and the wheel 420. The central through hole of the rotating wheel 420 is a central through hole 4212 of the inner cylinder 421.
It will be appreciated that the shape of the wheel 420 may be other than cylindrical, such as elliptical cylindrical. Preferably, the runner 420 has a cylindrical shape.

It will be appreciated that when a force is applied to the pawl assembly 300 and moves it away from the wheel 420, the wheel 420 rotates about the mounting shaft 4112 to release the traction member 430 while compressing the reset member 440. When the jaw assembly 300 is not subjected to an external force, the reset member 440 is deformed again, the rotating wheel 420 rotates in a reverse direction, and the rotating wheel 420 winds the pulling member 430 to pull the jaw assembly 300 to move towards the direction of the pulling module 400.

When the rotating wheel 420 rotates in a first direction, the rotating wheel 420 synchronously winds the first pulling member and the second pulling member, so that the pulling module 400 synchronously draws the two jaw assemblies 300 toward the pulling module 400, and when the rotating wheel 420 rotates in a second direction, which is opposite to the first direction, for example: the first direction is clockwise, the second direction is counterclockwise, or the first direction is counterclockwise and the second direction is clockwise, the traction module 400 releases the first traction member and the second traction member synchronously, the two jaw assemblies 300 can move away from the traction module 400 synchronously, and the movement of the two jaw assemblies 300 relative to the traction module 400 is synchronous. Further, the shape of the rotating wheel 420 is circular, so that when the rotating wheel 420 rotates, the lengths of the first pulling member and the second pulling member which are wound or released by the rotating wheel 420 are the same, and the symmetry and the balance of the positions of the two jaw assemblies 300 relative to the pulling module 400 are improved.
The tension wheel 450 is sleeved on the positioning protrusion 4113 and can rotate around the positioning protrusion 4113. The tension wheel 450 is used for applying a force to the traction member 430 to straighten the traction member 430, so as to prevent the other end of the traction member 430 from directly leading out from the tangential direction of the rotating wheel 420 and being connected to the fixed block 340.
In some embodiments, when the restoring element 440 is a spring (not shown), the box body 411 or the box cover 412 partially extends to form an abutting plate (not shown) extending between the inner cylinder 421 and the outer cylinder 422. One end of the spring is fixedly tied to the connecting plate 423, and the other end of the spring faces the abutting plate, and the abutting plate is used for abutting and compressing the spring.
It can be understood that the traction module 400 is provided with two traction members 430 at the same time to connect with one set of the jaw assemblies 300, the two traction members 430 are folded on the rotating wheel 420, and the two sets of the jaw assemblies 300 are symmetrically arranged at two ends of the traction module 400, so that when the rotating wheel 420 rotates to compress the reset member 440, the jaw assemblies at two sides of the traction module 400 can move by the same distance. When the two jaw assemblies are clamped on the hub, the external force is removed, the reset piece 430 recovers deformation, the rotating wheel rotates reversely, so that the two traction pieces are straightened automatically, the position between the two jaw assemblies 300 is adjusted adaptively, and the traction module 400 is always positioned at the center of the two jaw assemblies.
In some embodiments, the accommodating box 410 may be omitted, and a positioning shaft (not shown) identical to the mounting shaft 4112 is required to extend from the main body 100, and the rotating wheel 420 may be directly sleeved on the positioning shaft, so that the rotating wheel 420 can rotate relative to the main body 100. When the reset member 440 is a torsion spring, one end of the torsion spring is fixed to the main body, and the other end of the torsion spring abuts against the rotating wheel 420, so that the torsion spring is compressed when the rotating wheel 420 rotates; when the reset member 440 is a spring, the main body extends to form the abutting plate, one end of the spring is fixed to the connecting plate 423, the other end of the spring faces the abutting plate, and the abutting plate is used for abutting and compressing the spring.

Through the structure of the traction module 400, the first traction piece and the second traction piece stretch the same length synchronously relative to the traction module, so that the jaw assemblies 300 on both sides of the traction module 400 move the same distance after the first traction piece and the second traction piece are straightened, the traction module 400 is located at the centers of the jaw assemblies 300 on both sides at each moment, the moving distance of the jaw assemblies 300 on both sides does not need to be controlled deliberately, and when the traction module is installed and used, the jaws 330 of the jaw assemblies 300 on both sides of the traction module 400 only need to be stretched to be matched with the diameter of the hub, so that the jaw assemblies can be directly clamped to the hub.
As shown in fig. 9, in some embodiments, the hub gripping apparatus 900 further includes a handle 500, the handle 500 being connected to the jaw assembly 300.

One end of the tension spring 630 is sleeved on the first connecting shaft 640, and the other end of the tension spring 630 is sleeved on the second connecting shaft 650.
In some embodiments, in order to prevent the tension spring 630 from deviating, the effect of hooking the tire by the hook 620 is affected, the mounting block 4116 is in a U shape, the other end of the connecting rod 610 is hollow, two spacing blocks 660 arranged at intervals are sleeved on the first connecting shaft 640 and the second connecting shaft 650, and the end of the tension spring 630 is sleeved on a gap between the two spacing blocks 660, so as to limit the position of the tension spring 630.
Understandably, when the other end of the connecting rod 610 swings towards a direction away from the main body 100, the tension spring 630 will be stretched, after the hook claw 620 hooks the tire, the tension spring 630 recovers deformation and will pull the connecting rod 610 to swing towards a direction close to the main body 100, and the hook claw 620 correspondingly moves towards the main body 100 and enables the hook head at the other end to bite the tire, so that the hub clamping device 900 is tightly installed between the hub and the tire.
It should be understood that, in order to achieve the tight installation of the clamping jaw assembly 300 between the wheel hub and the tire and the uniform stress on the wheel hub clamping device 900, at least one set of the clamping jaw assemblies 600 is respectively disposed on two opposite sides of the main body 100, that is, at least two sets of the clamping jaw assemblies 600 are respectively disposed on two opposite sides of the main body 100, in this case, the mounting seat 4121 needs to be correspondingly provided with a plurality of structures for the connecting rod 610 to hinge, and the box body 411 also needs to be correspondingly provided with a plurality of the mounting blocks 4116. In this embodiment, there are two sets of the clamping jaw assemblies 600, and the two sets of the clamping jaw assemblies 600 are installed on two sides of the traction module 400 oppositely, and each set of the clamping jaw assemblies 600 is substantially perpendicular to the clamping jaw assembly 300.

Further, in order to make the hooking claw 620 engage with the tire more tightly, the number of the tension springs 630 may be increased appropriately, that is, the tension springs 630 may be one, two, three or more. Similarly, one end of each of the tension springs 630 is sleeved on the first connecting shaft 640, and the other end thereof is sleeved on the second connecting shaft 650.
In some embodiments, if the connecting rod 610 is made of an elastic material (e.g., rubber band), one end of the connecting rod 610 is directly hinged to the mounting block 4116, and the other end is directly hinged to the hook claw 620. Similarly, after the hook 620 hooks the tire, the link 610 is stretched, and at this time, the link 610 returns to elastic deformation and pulls the hook 620 to move toward the main body 100, so as to generate a pulling force to make the hook 620 hook the tire.
In some embodiments, the jaw assembly 600 further comprises a holding block 670, the holding block 670 is fixedly mounted on the hook 620, and the holding block 670 is used for holding the hook 620 by a user.

Further, since the two connecting rods 610 are symmetrically arranged relative to the main body 100, that is, symmetrical to the central axis P of the main body 100, and are simultaneously matched with the centers of the jaw assemblies 300 of which the traction modules 400 are located at two sides, the hub clamping device 900 can keep the positioning holes 120 and the central axis of the hub coinciding from two directions, so that the accuracy and stability of the mutual coincidence between the central axis of the hub clamping device 900 and the central axis of the hub are improved, and the accuracy of the positioning of the automobile wheel is improved.
When the wheel hub traction device is installed and used, a user pulls the handles 500 positioned on two sides of the traction module 400 at the same time, so that the jaw assemblies 300 slide in the sliding groove 211 to a required position through the sliding block 220, at the moment, the fixing block 340 pulls the traction piece 430 to drive the rotating wheel 420 to rotate and compress the reset piece 440, then the jaws 330 are inserted into a gap between the wheel hub and a tire, the positions of the two sets of jaw assemblies 300 are adjusted according to the diameter of the wheel hub, after the jaws 330 are inserted into the gap, the handles 500 are loosened, and the elastic deformation of the reset piece 440 provides a tensile force to pull the traction piece tightly, so that the jaws 330 clamp the wheel hub together. After the device is installed, the positions of the claws at the two sides relative to the traction module are the same, so that the central axis of the traction module 400 can be coincided with the central axis of the hub, and the subsequent detection is convenient.

Further, the link 610 is then swung, the tension spring 630 is stretched, referring to fig. 13, after the hook 620 hooks the tire, the link 610 is released, the tension spring 630 recovers elastic deformation to pull the link 610 to swing in a direction close to the body 100, and the hook head of the hook 620 swings in a direction toward the center of the tire, so that the hook 620 bites the tire, thereby preventing the claw assembly 300 from being disengaged from the tire and the hub.
It will be appreciated that in the process, the length of the rotating wheel 420 for releasing and retracting the pulling member 430 is the same, and the jaw assemblies 300 on both sides of the pulling module 400 will move the same distance to ensure that the centers of the two sets of jaw assemblies 300 are at the center of the pulling module 400.
