Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 6, which is the first embodiment of the present invention, provides a cartilage sliding wear modeling device, which includes a moving component 200, an adjusting component 300 and a main component 100, which can simulate different degrees of cartilage damage in combination.

[0030] The moving assembly 200 includes a moving part 201, including a friction head 201a, a moving rod 201b, a moving block 201c and a push rod 201d.

[0031] When it is necessary to simulate cartilage damage, the movement of the push rod 201d will drive the movement of the moving block 201c, and the movement of the moving block 201c will drive the movement of the moving rod 201b. The movement of the moving rod 201b can drive the friction head 201a to move. At this time, the reciprocating movement of the friction head 201a can simulate different degrees of cartilage damage.

[0032] The adjustment assembly 300 is arranged on the push rod 201d, and includes an adjustment block 301a, a threaded rod 301b, a knob 301c and a driving block 301d.

The driving block 301d drives the knob 301c to rotate, and the rotation of the knob 301c drives the threaded rod 301b to rotate. The rotation of the threaded rod 301b can drive the adjustment block 301a to move, and the adjustment block 301a drives the push rod 201d to move. The moving distance of the push rod 201d can be adjusted by moving the push rod 201d to different positions.

[0036] Specifically, the moving assembly 200 further includes a support member 202, which is disposed on the moving block 201c. A positioning plate 202a is sleeved on the outer side of the moving rod 201b, and the moving rod 201b and the positioning plate 202a are movably connected.

[0037] The positioning plate 202a is fixed to one end of the handle 101. The positioning plate 202a can support the moving rod 201b to prevent the moving rod 201b from deviating when moving.

[0038] Specifically, a moving sleeve 202b is fixed to one side of the moving block 201c, a supporting rod 202c is inserted into one side of the moving sleeve 202b, and the moving sleeve 202b and the supporting rod 202c are movably connected.

[0039] There are two moving sleeves 202b, which are fixed on both sides of the moving block 201c respectively. There are two support rods 202c, which are both inserted into the moving sleeves 202b. When the moving block 201c moves, the moving sleeves 202b will be driven to move on the support rods 202c, so as to support the moving block 201c and prevent the moving block 201c from shifting during movement.

[0040] Specifically, a connecting plate 202d is fixed to one side of the support rod 202c, and a bottom plate 202e is fixed to the bottom of the connecting plate 202d.

[0041] There are four connecting plates 202d, all of which are fixed at one end of the support rod 202c. The connecting plate 202d can be used to support the support rod 202c to prevent the support rod 202c from shifting. The bottom plate 202e is fixed to the inner wall of the handle 101. The bottom plate 202e can be used to support the connecting plate 202d to prevent the connecting plate 202d from shifting.

[0042] Specifically, the adjustment assembly 300 further includes a movable member 302, which is disposed on the threaded rod 301b. A positioning block 302a is fixed to one side of the threaded rod 301b, and the positioning block 302a is rotatably connected to the threaded rod 301b via a rotating shaft.

[0043] There are two positioning blocks 302a, which are respectively arranged at both ends of the threaded rod 301b. The threaded rod 301b can be supported by the positioning blocks 302a to prevent the threaded rod 301b from deflecting.

[0044] Specifically, a rotating disk 302b is fixed to one side of the positioning block 302a, and a sliding block 302c is fixed to one side of the adjusting block 301a.

[0045] A motor is fixed on one side of the turntable 302b, and the motor is fixed to the inner wall of the handle 101. The turntable 302b can be driven to rotate by starting the motor, and the rotation of the turntable 302b can drive the adjusting block 301a to move. The movement of the adjusting block 301a can drive the push rod 201d to move. A sliding groove corresponding to the slider 302c is opened on one side of the turntable 302b. When the adjusting block 301a is moved, the slider 302c can be driven to slide in the sliding groove. At this time, the adjusting block 301a can be supported to prevent the adjusting block 301a from offsetting when moving.

[0046] Example 3

[0047] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0048] Specifically, a movable column 302d is fixed on one side of the driving block 301d, a driving sleeve 302e is sleeved on the outer side of the movable column 302d, and the movable column 302d is movably connected to the driving sleeve 302e. A positioning plate 302f is sleeved on the outer side of the movable column 302d, and the positioning plate 302f is rotatably connected to the driving sleeve 302e through a rotating shaft.

[0049] When the driving block 301d needs to be engaged with the knob 301c, the positioning plate 302f is moved by moving the driving sleeve 302e. The positioning plate 302f can drive the movable column 302d to move when it moves. The movement of the movable column 302d can drive the driving block 301d to engage with the knob 301c. Then, the movable column 302d is rotated. The rotation of the movable column 302d drives the driving block 301d to rotate. The rotation of the driving block 301d can drive the knob 301c to rotate.

[0050] Specifically, a hinged rod 302g is provided at one end of the driving sleeve 302e, and the hinged rod 302g is hinged to one end of the driving sleeve 302e. A positioning frame 302h is sleeved on the outer side of the hinged rod 302g. The hinged rod 302g and the positioning frame 302h are rotatably connected through a rotating shaft.

[0051] A shift plate is fixed at one end of the hinged rod 302g. The hinged rod 302g can be driven to move by shifting the shift plate. The movement of the hinged rod 302g can drive the drive sleeve 302e to move. The positioning frame 302h is fixed to one side of the handle 101. The positioning frame 302h can support the hinged rod 302g to prevent the hinged rod 302g from deviating.

[0052] Specifically, a rotating plate 302i is fixed to one side of the hinge rod 302g, a torsion spring 302j is fixed to one side of the rotating plate 302i, and the torsion spring 302j is fixed to the inner wall of the positioning frame 302h.

[0053] When the hinged rod 302g is moved, the rotating plate 302i will be driven to rotate. The rotation of the rotating plate 302i can apply a torsional force to the torsion spring 302j. At this time, the driving block 301d will engage with the knob 301c. When the two need to be separated, the hinged rod 302g is released. At this time, the rotation force of the torsion spring 302j can drive the driving block 301d to separate from the knob 301c.

[0054] Specifically, it also includes a main body component 100, which is arranged on the connecting plate 202d, including a handle 101 and a bracket 102. The handle 101 is sleeved on the outside of the connecting plate 202d, and the bracket 102 is located at the bottom of the handle 101.

[0055] A trigger is provided on one side of the handle 101. When the user presses the trigger, the motor can be started to drive the turntable 302b to rotate. When the trigger is released, the motor can stop rotating. The motor belongs to the existing technology, so it is not elaborated in detail. The friction head 201a can be supported by the setting of the handle 101 to prevent the friction head 201a from shifting. The handle 101 can be supported by the setting of the bracket 102. The bracket 102 is connected to the handle 101 through a ball joint, and the angle and height of the handle 101 can be adjusted.

[0056] When in use, first adjust the bracket 102 to a suitable height, then hold the handle 101 and press the trigger to drive the motor to rotate. When the motor rotates, it will drive the turntable 302b to rotate. The rotation of the turntable 302b will drive the adjustment block 301a to move. The movement of the adjustment block 301a can drive the push rod 201d to move. At this time, the push rod 201d will drive the moving block 201c to move. The movement of the moving block 201c will drive the moving rod 201b to move. The moving rod 201b can drive the friction head 201a to move. At this time, the reciprocating movement of the friction head 201a can simulate different degrees of cartilage damage.

[0057] When it is necessary to simulate different degrees of cartilage damage, the moving distance of the push rod 201d needs to be adjusted. First, the dial plate is toggled to drive the hinged rod 302g to move, and the movement of the hinged rod 302g drives the drive sleeve 302e to move. When the hinged rod 302g is moved, the rotating plate 302i is driven to rotate. The rotation of the rotating plate 302i can apply a torsional force to the torsion spring 302j. The movement of the drive sleeve 302e drives the positioning plate 302f to move. When the positioning plate 302f moves, it can drive the movable column 302d to move. The movement of the movable column 302d can drive the drive block 301d to engage with the knob 301c, and then the movable column 302d is rotated. The rotation of the movable column 302d drives the drive block 301d to rotate. The rotation of the driving block 301d can drive the knob 301c to rotate, and the rotation of the knob 301c can drive the threaded rod 301b to rotate. The rotation of the threaded rod 301b can drive the adjusting block 301a to move. When the adjusting block 301a is moved, the slider 302c can be driven to slide in the slide groove. At this time, the adjusting block 301a can be supported to prevent the adjusting block 301a from deviating during movement. The adjusting block 301a drives the push rod 201d to move. By moving the push rod 201d to different positions, the moving distance of the push rod 201d can be adjusted, and then the hinged rod 302g is released. At this time, the driving block 301d can be driven to separate from the knob 301c by the rotating force of the torsion spring 302j.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
