[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please refer to the following: Figures 1-4This utility model provides a technical solution: an easily assembled ultrasonic handpiece, including a rear end 1 and a front end. The outer surface of the front end is provided with a front housing 2, and the rear end 1 is provided with a rear housing 3. Receiving grooves 4 are formed at the ends of the front housing 2 and the rear housing 3 that are close to each other. A button 5 is provided inside the receiving groove 4. An adjusting rod 6 is fixedly connected to the bottom outer surface of the button 5. A connecting plate 7 is fixedly connected to the bottom outer surface of the adjusting rod 6. A connecting rod 8 is fixedly connected to the top outer surface of the connecting plate 7. A limiting block 9 is fixedly connected to the top outer surface of the connecting rod 8. A limiting groove 10 is formed on the inner surface of the rear housing 3. Specifically, this ultrasonic handpiece is... During assembly, insert the rear end 1 of the handle into the front end of the handle, so that the front shell 2 corresponds to the rear shell 3. When the rear shell 3 contacts the limiting block 9, the spring 11 deforms as the rear shell 3 is pushed in. When the limiting block 9 contacts the limiting groove 10, the limiting block 9 is inserted into the limiting groove 10 under the elastic force of the spring 11. The limiting block 9 limits the front shell 2 and the rear shell 3. During disassembly, press down the button 5. The button 5 drives the adjusting rod 6 to move the connecting plate 7 downward, thereby causing the connecting rod 8 to move the limiting block 9 downward, so that the limiting block 9 disengages from the inside of the limiting groove 10, thereby disassembling the front end and the rear end 1 of the handle.

[0021] In this embodiment, a sensor pin 12 is provided at the front end of the handle, and a sensor slot 13 corresponding to the sensor pin 12 is provided at the rear end of the handle. Specifically, when the front end of the handle and the rear end of the handle are spliced ​​together, the sensor pin 12 is inserted into the sensor slot 13, so that the front end of the handle and the rear end of the handle form a whole.

[0022] In this embodiment, a horizontal plate is fixedly connected inside the rear housing 3, and an adjusting rod 6 moves through the horizontal plate. A spring 11 is fixedly connected to the top outer surface of the connecting plate 7. The top outer surface of the spring 11 is fixedly connected to the bottom outer surface of the horizontal plate. The spring 11 is sleeved around the connecting rod 8. Specifically, the elastic force of the spring 11 causes the limiting block 9 to be inserted into the limiting groove 10, and the connecting rod 8 limits the spring 11 to prevent the spring 11 from tilting.

[0023] In this embodiment, slide bars 14 are fixedly connected to both the left and right sides of the rear end 1 of the handle, and limiting grooves 10 adapted to slide bars 14 are opened on the inner walls of both the left and right sides of the front end shell 2. The slide bars 14 are slidably connected to the inside of the limiting grooves 10. Specifically, when the front end shell 2 and the rear end shell 3 are assembled, the slide bars 14 slide inside the limiting grooves 10. The rear end 1 and the front end of the handle are positioned by the connection between the slide bars 14 and the limiting grooves 10.

[0024] In this embodiment, the side of the limiting block 9 near the rear end 1 of the handle has a smooth and inclined outer surface. Specifically, by setting a smooth and inclined outer surface, the limiting block 9 can be squeezed when the rear end 1 of the handle is assembled with the front end of the handle, so that the spring 11 is deformed.

[0025] In this embodiment, a sliding groove is provided inside the rear housing 3 on one side of the limiting groove 10. The depth of the limiting groove 10 is greater than the depth of the sliding groove. Specifically, when the rear housing 3 is assembled with the front housing 2, the limiting block 9 moves along the sliding groove, and the spring 11 deforms. When the limiting block 9 contacts the limiting groove 10, the spring 11 drives the limiting block 9 to insert into the interior of the limiting groove 10.

[0026] Working principle: When using this utility model, during the assembly of the ultrasonic handpiece, the rear end 1 of the handpiece is inserted into the front end of the handpiece, so that the front shell 2 corresponds to the rear shell 3. When the rear shell 3 contacts the limiting block 9, the spring 11 deforms as the rear shell 3 is pushed in. When the limiting block 9 contacts the limiting groove 10, the limiting block 9 is inserted into the limiting groove 10 under the elastic force of the spring 11. The limiting block 9 limits the front shell 2 and the rear shell 3. When disassembling, press the button 5 down. The button 5 drives the adjusting rod 6 to move the connecting plate 7 down, thereby causing the connecting rod 8 to move the limiting block 9 down, so that the limiting block 9 disengages from the inside of the limiting groove 10, thereby disassembling the front end and the rear end 1 of the handpiece.

[0027] 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.
