They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figures 1-9 This utility model provides a technical solution: a handheld ultrasonic rehabilitation instrument shell structure, the handheld ultrasonic rehabilitation instrument shell structure includes: a body 1, the body 1 includes an outer shell 2 and an inner shell 3, the inner shell 3 is provided with a first abutting cylinder 5 and a second abutting cylinder 7, the outer surface of the inner shell 3 is provided with an insert plate 4, the inner surface of the inner shell 3 is provided with an inner plate 8, the cross section of the inner plate 8 is trapezoidal, and the inclined surface of the inner plate 8 faces the inside of the inner shell 3;

[0029] The outer shell 2 has slots 10 on its outer periphery and a base frame 12 inside. A first insert rod 14 is fixed on the base frame 12. A moving ring 18 is slidably disposed on the surface of the first insert rod 14. A spring 19 is disposed between the moving ring 18 and the base frame 12. A connecting plate 16 is disposed on the inner side surface of the outer shell 2 and a through groove 17 is disposed on the surface of the connecting plate 16.

[0030] In use, the outer shell 2 and the inner shell 3 are connected by the connection plate 16 and the inner plate 8. The connection between the first abutting cylinder and the first insert 14, and the connection between the second abutting cylinder and the second insert 15, provide guidance and support for the connection between the outer shell 2 and the inner shell 3. The spring 19 and the moving ring 18 can provide buffer for the connection between the outer shell 2 and the inner shell 3, improve the stability of the connection between the outer shell 2 and the inner shell 3, and make the surface of the machine body 1 flat and regular, which is convenient for gripping and operation.

[0031] Example 2: Based on Example 1, the insert plate 4 can be inserted into the slot 10. There are several insert plates 8, which are evenly distributed inside the inner shell 3. There are several connecting plates 16, which are evenly distributed inside the outer shell 2. Side plates 9 are provided on both sides of the insert plate 8. The abutment plate can extend into the inner side of the two sets of side plates 9. Both the insert plate 8 and the abutment plate are made of deformable plastic. The abutment plate is square. The end face of the abutment plate can contact and slide with the inclined surface of the insert plate 8. The insert plate 8 can be inserted into the through slot 17.

[0032] The second abutting cylinder 7 is provided in two sets, and the two sets of second abutting cylinder 7 are symmetrically distributed about the central axis of the inner shell 3. The second insertion rod 15 is provided in two sets, and the two sets of second insertion rod 15 are symmetrically distributed about the central axis of the outer shell 2. The second insertion rod 15 can be inserted into the second abutting cylinder 7. The base frame 12 is provided in three sets, and the line connecting the top centers of the three sets of base frames 12 forms an isosceles triangle. The three sets of base frames 12 are located at the three vertices of the isosceles triangle. The arrangement of the first abutting cylinder 5 in the inner shell 3 is the same as the arrangement of the base frame 12 in the outer shell 2.

[0033] In use, when installing the outer shell 2 and the inner shell 3, the first insertion rod 14 and the first abutment cylinder must be aligned, and the second insertion rod 15 and the second abutment cylinder must also be aligned. This defines the connection position between the outer shell 2 and the inner shell 3. As the insertion rods are continuously inserted into the abutment cylinders, the insertion plate 4 will be inserted into the slot 10, and at the same time, the connecting plate 16 will extend into the inner shell 3. The connecting plate 16 will contact and abut against the inner insert plate 8, and the connecting plate 16 will continue to advance along the inclined edge of the inner insert plate 8 until the inner insert plate 8 is fully inserted. In slot 17, the housing is assembled. After the second insert 15 is inserted into the second abutment cylinder 7, the second abutment cylinder 7 will contact the moving ring 18 and push it continuously, causing the spring 19 to be compressed. The spring 19 will give the second abutment cylinder 7 a thrust, thereby giving the outer shell 2 a thrust. When the inner plate 8 is inserted into the through slot 17, the thrust is at its maximum and continues to exist, thereby allowing the inner plate 8 to abut against the connecting plate 16, preventing the inner plate 8 from shaking in the through slot 17 and improving the stability of the body 1.

[0034] Example 3: Based on Example 2, the lower half of the body 1 is configured as a gripping part 6, the first abutting tube 5 is located above the gripping part 6, the second abutting tube 7 is located inside the gripping part 6, and a rubber pad 11 is laid inside the slot 10;

[0035] During use, the operator manually holds the grip part 6 and presses the grip part 6 continuously to stabilize it, thus reducing the pressure on the parts above the grip part 6. The spring 19 and the moving ring 18 are provided to improve the stability of the body 1. After the insert plate 4 is inserted into the slot 10, the insert plate 4 will press against the rubber pad 11 to improve the sealing of the body 1 after assembly.

[0036] The base frame 12 is fixed inside the outer shell 2. A wing plate 13 is fixed on the outer side of the base frame 12. Several wing plates 13 are provided and evenly distributed on the outer side of the base frame 12. The bottom of the wing plate 13 is fixedly connected to the outer shell 2. The cross section of the wing plate 13 is trapezoidal.

[0037] In use, the several evenly distributed wing plates 13 can provide lateral support for the base frame 12, improve the stability of the base frame 12 structure, and ensure the stable docking of the first insertion rod 14 and the first abutting cylinder 5.

[0038] In actual use, the outer shell 2 and the inner shell 3 are connected by the connection plate 16 and the inner plate 8. The connection between the first abutting cylinder and the first insert 14, and the connection between the second abutting cylinder and the second insert 15, provides guidance and support for the connection between the outer shell 2 and the inner shell 3. The spring 19 and the moving ring 18 provide buffering for the connection between the outer shell 2 and the inner shell 3, improving the stability of the connection between the outer shell 2 and the inner shell 3. This makes the surface of the body 1 flat and regular, which is convenient for gripping. This avoids the problem that in the prior art, the outer shell of the ultrasonic rehabilitation instrument is usually connected by bolts, which requires the shell to extend outside the shell to facilitate bolt installation, increases the overall area of ​​the shell, and causes the shell surface to be irregular. In addition, for the grip-type ultrasonic rehabilitation instrument, the irregular shell surface makes it inconvenient to hold.

[0039] 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.
