[0035] Further, in some implementations of this embodiment, Figures 3 to 6 As shown, a sliding hole 32 is formed on the eccentric wheel 31 , and the mounting seat 11 is inserted into the sliding hole 32 .

[0036] In this embodiment, if Figure 4 As shown, the sliding hole 32 is an arc-shaped hole, which is opened on the circumferential side of the rotation center axis of the eccentric wheel 31.

[0037] Further, in some implementations of this embodiment, Figure 3 and Figure 4 As shown, it also includes: a support ring 12 and a rod 33. The support ring 12 is mounted on the base plate 10, and the cover is arranged outside the mounting seat 11 and the eccentric wheel 31, and the side wall of the support ring 12 is provided with an annular hole 13, and the annular hole 13 is distributed along the circumference of the support ring 12, and the locking member 30 is provided with a sliding groove 34, and the support ring 12 is slidably mounted in the sliding groove 34; the rod 33 is mounted on the side wall of the eccentric wheel 31, and the rod 33 is slidably penetrated in the annular hole 13.

The locking member 30 is rotated, the annular hole 13 and the support ring 12 are threadedly fastened, and the annular hole 13 is driven to move along the central axis of the annular hole 13 toward the direction close to the base plate to abut against one end of the fixing member 21 close to the locking member 30, thereby driving multiple fixing members 21 to rotate relative to the bracket 24, and the other end abuts against the peripheral side of the wheel hub, and the eccentric wheel 31 is rotated to abut against the inner wall of the locking member 30 to further fix the relative position between the locking member 30 and the base plate 10, thereby improving the stability of the fixation. After loosening the eccentric wheel 31, it is convenient to adjust the position of the wheel hub, the repair position, and the operation.

[0039] Furthermore, in some implementations of this embodiment, it further includes: a plurality of elastic elements. The plurality of elastic elements are correspondingly installed between the plurality of fixing members 21 and the mounting plate 23 .

[0040] In this embodiment, the elastic element may be a retaining spring or a spring, which is installed between the fixing member 21 and the mounting plate 23 to provide a pulling force for the fixing member 21, driving the fixing member 21 to rotate in a direction away from the center axis of the wheel hub when not abutted by the locking member 30, thereby preventing interference with the wheel hub during installation.

[0041] In summary, when using an electric vehicle wheel hub repair tool to fix the wheel hub, the wheel hub is abutted against the mounting platform 20, the locking piece 30 is rotated, and the locking piece 30 is driven to press against the end of multiple fixing pieces 21 installed between the mounting plate 23 and the base plate 10. Through the threaded connection, the locking piece 30 moves along the central axis of the mounting column 22 toward the direction close to the base plate 10, and the multiple fixing pieces 21 abut against the side wall of the wheel hub together to position the central axis of the wheel hub. Multiple elastic elements are installed to increase the resilience of the fixing piece 21 to prevent collision between the spokes of the wheel hub and the multiple fixing pieces 21. The central axis of the wheel hub and the mounting platform 20 is locked, which is convenient for rotating the wheel hub to adjust the position to be repaired in real time. The rod 33 is rotated to drive the eccentric wheel 31 to rotate, so that the eccentric wheel 31 abuts against the inner wall of the locking piece 30 to fix the positional relationship between the locking piece 30 and the support ring 12, thereby improving the stability of the installation, reducing the cumbersome steps of the installation, and improving the installation efficiency.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
