[0008] A drive shaft is installed inside the mounting ring, and the rear end of the drive shaft is connected to the output end of the starter motor.

[0009] A turntable is mounted at the front end of the drive shaft, and a grinding arc-shaped plate is provided around the edge of the turntable.

[0010] Furthermore, the mounting ring is provided with a connecting portion.

[0011] Furthermore, the connecting part is provided with a threaded head, and the handle is provided with a threaded groove corresponding to the threaded head.

[0012] Furthermore, the mounting ring is equipped with a bearing that mates with the drive shaft.

[0013] Furthermore, the mounting ring is provided with an auxiliary ring.

[0014] Furthermore, the auxiliary ring is equipped with a second drive shaft bearing.

[0015] Furthermore, the mounting ring is connected to the auxiliary ring by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] It adopts a convenient handheld polishing method, which is simple, effective and convenient for polishing the braces;

[0018] The design employs automation, utilizing a motor to drive the drive shaft to rotate, and using a grinding arc blade to grind the mold. Attached Figure Description

[0020] Figure 2 This is a schematic diagram of the mounting ring structure of this utility model;

[0021] Figure 3 This is a schematic diagram of the threaded head structure of this utility model. Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figure 1-2 This utility model provides a technical solution:

[0025] A grinding device for printing 3D rehabilitation braces includes a handle 7 and a starter motor 6. The starter motor 6 serves as a power source. To facilitate maintenance and disassembly of the device, a detachable mounting ring 5 is installed at the top of the handle 7. A drive shaft 4 is installed inside the mounting ring 5. The rear end of the drive shaft 4 is connected to the output end of the starter motor 6. The starter motor 6 drives the drive shaft 4 to rotate. A turntable 1 is installed at the front end of the drive shaft 4. A grinding arc-shaped blade 2 is provided around the edge of the turntable 1. The high-speed rotating grinding arc-shaped blade 2 is used to remove burrs from the brace and shape it.

[0026] like Figure 1 , 3 As shown:

[0027] The mounting ring 5 is provided with a connecting part 8. In order to achieve a detachable connection, a threaded head 81 is installed on the connecting part 8, and a threaded groove corresponding to the threaded head 81 is opened on the handle 7 to connect the two by thread. The parts can be removed by screwing.

[0028] like Figure 2 As shown:

[0029] To enable the installation and rotation of the drive shaft 4, a bearing 51 is provided inside the mounting ring 5 to cooperate with the drive shaft 4, so that the two are interference-fitted. The drive shaft 4 can rotate within the bearing 51. The mounting ring 5 is also provided with an auxiliary ring 3, and a second bearing 31 for the drive shaft 4 is installed in the auxiliary ring 3, so that the two are interference-fitted. The drive shaft 4 rotates in the second bearing 31, so that the rotation of the drive shaft 4 is smooth and does not affect the use. To enhance stability, the mounting ring 5 is connected to the auxiliary ring 3 by bolts.

[0030] Working principle:

[0031] When grinding is required, start motor 6 is turned on, and the output end drives drive shaft 4 to rotate in mounting ring 5 and auxiliary ring 3. Turntable 1 at one end of drive shaft 4 drives grinding arc plate 2 to rotate at high speed to grind the support.

[0032] At the same time, the mounting ring 5 can be removed from the handle 7 by twisting, making it easy to replace and repair.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
