[0029] Please refer to Figures 1 to 6 The present invention proposes a therapeutic device 100, comprising: a therapeutic head 10, wherein the therapeutic head 10 is provided with a connecting shaft 11, and a groove 111 is provided on the outer wall of the connecting shaft 11; a handle 20, wherein the therapeutic head 10 and the handle 20 are detachably connected, the handle 20 is provided with a connecting hole 21, and the handle 20 is provided with a mounting groove 22, wherein the mounting groove 22 is located on the inner circumference of the connecting hole 21, and the mounting groove 22 is communicated with the connecting hole 21; an elastic member 30, wherein the elastic member 30 is installed in the mounting groove 22; wherein, when the connecting shaft 11 is inserted into the connecting hole 21, the elastic member 30 is deformed and stuck in the groove 111; when the connecting shaft 11 is pulled out of the connecting hole 21, the elastic member 30 is deformed, and the groove 111 is disengaged from the elastic member 30.

[0030] Specifically, the therapeutic device 100 includes a treatment head 10 and a handle 20. The treatment head 10 is inserted into the handle 20 for use and removed after use. A groove 111 is defined on the connecting shaft 11 of the treatment head 10, and an elastic member 30 is mounted on the handle 20. When the treatment head 10 and the handle 20 are plugged in, the treatment head 10 deforms the elastic member 30 and snaps it into the groove 111, completing the connection. To remove the treatment head 10, simply pull it out in the opposite direction, deforming the elastic member 30 and disengaging the groove 111 from the elastic member 30, enabling quick removal.

[0031] The treatment head 10 is inserted into the connecting hole 21 of the handle 20 through the connecting shaft 11 to achieve plug-in, and a mounting groove 22 is provided in the connecting hole 21, and the mounting groove 22 is used to install the elastic member 30. When the treatment head 10 is inserted, the elastic member 30 is deformed by the extrusion between the connecting shaft 11 at the end of the treatment head 10 and the connecting hole 21 of the handle 20, and the elastic member 30 is stuck in the groove 111, thereby achieving the fixation of the treatment head 10 and the handle 20.

[0032] The shape of the groove 111 can be set as an annular groove or a key groove, and the specific shape can be selected according to the specific structure of the elastic member 30 and actual needs.

[0033] The shape of the mounting groove 22 can be set as an annular groove or a simple notch. The specific shape can be selected according to the specific structure of the elastic member 30 and actual needs.

[0034] The elastic member 30 deforms to lock the treatment head 10 and handle 20, making connection quick and easy. Disassembly requires only a moderate amount of force, minimizing time and increasing convenience. Furthermore, thanks to the elastic locking mechanism, the treatment head 10 is less likely to become loose or fall off due to vibration or external forces during use, ensuring safety.

[0035] The technical solution of the present invention is to provide a groove 111 on the connecting shaft 11 of the treatment head 10, provide a mounting groove 22 at the position of the connecting hole 21 of the handle 20, and install the elastic member 30 in the mounting groove 22. When the treatment head 10 is inserted into the handle 20, the elastic member 30 is deformed by the squeezing between the connecting shaft 11 and the handle 20. The elastic member 30 provides an axial locking force, thereby achieving the fixation of the treatment head 10 and the handle 20. When disassembly is required, a certain external force is provided to pull it out in the opposite direction, so that quick disassembly can be achieved, and the operation is extremely convenient.

[0036] In an embodiment of the present invention, an outer wall of the end of the connecting shaft 11 is provided with an introduction slope 112 , and the circumferential dimension of the introduction slope 112 gradually increases from the end of the connecting shaft 11 toward the treatment surface of the treatment head 10 .

[0037] Detailed, such as Figure 5 A guide bevel 112 is provided on the side wall of the connecting shaft 11. When the connecting shaft 11 is inserted into the connecting hole 21, the design of the guide bevel 112 can help to more easily align the connecting shaft 11 with the connecting hole 21 of the handle 20, facilitating positioning and insertion. Due to the presence of the guide bevel 112, even if the connecting shaft 11 is not completely aligned during insertion, the guide bevel 112 will still serve as a guide. The provision of the guide bevel 112 helps to reduce resistance during insertion, making the operation easier and the connection process smoother. This design makes the device easier to operate, avoids damage to the internal structure of the connecting shaft 11 or the handle 20 due to forced insertion, and improves the overall user experience.

[0038] In an embodiment of the present invention, the groove 111 includes a first side wall 1111 , and the circumferential dimension of the first side wall 1111 gradually decreases from the end of the connecting shaft 11 toward the treatment surface of the treatment head 10 .

[0039] It is worth noting that Figure 6The first sidewall 1111 of the recess 111 also serves as an inclined guide surface. This helps reduce resistance when removing the treatment head 10. When the treatment head 10 needs to be pulled out of the handle 20, the first sidewall 1111 helps overcome the locking force of the elastic member 30, making the removal process smoother and less difficult. Furthermore, the inclined guide surface acts as a buffer during the removal process, preventing damage to the connecting shaft 11 or other components within the handle 20 due to improper force.

[0040] Therefore, the connecting shaft 11 is fixed on the treatment head 10. The connecting shaft 11 is designed with an introduction slope 112 and a first side surface, that is, it has an insertion guide and a removal guide, making insertion and removal easier and more convenient to operate.

[0041] In an embodiment of the present invention, the angle formed by the first side wall 1111 and the central axis of the connecting shaft 11 is a first angle, and the angle formed by the introduction slope 112 and the central axis of the connecting shaft 11 is a second angle, and the first angle is greater than the second angle.

[0042] Specifically, when the treatment head 10 is inserted into the handle 20, the connecting shaft 11 can easily deform the elastic member 30 under the action of the introduction bevel 112, and can be inserted into the groove 111 of the connecting shaft 11. Since the first angle is greater than the second angle, the connecting shaft 11 relies on the first angle to provide a circumferential locking force toward the handle 20 under the action of the elastic member 30, so that the treatment head 10 remains on the handle 20.

[0043] like Figure 6 The smaller second angle makes the introduction slope 112 smoother, helping the treatment head 10 to align more easily and enter the connection hole 21 of the handle 20 during insertion, reducing insertion resistance. The larger first angle allows the first side wall 1111 to more quickly escape the range of action of the elastic member 30 during removal, thereby reducing the force required for removal and making disassembly easier. Furthermore, the larger first angle allows for a better fit between the first side wall 1111 and the elastic member 30 after insertion, increasing the stability of the connection and reducing the risk of accidental detachment of the treatment head 10 during use.

[0044] Reasonable angle design can reduce the wear on the connection parts during long-term use, extend the service life of the equipment, reduce the difficulty of operation, and improve the convenience and comfort of equipment use.

[0045] In an embodiment of the present invention, the groove 111 includes a second side wall 1112 . The first side wall 1111 is located between the introduction slope 112 and the second side wall 1112 . The second side wall 1112 is perpendicular to the central axis of the connecting shaft 11 .

[0046] Specifically, recess 111 is provided with a second sidewall 1112. This vertical second sidewall 1112 provides a stable support surface for the elastic member 30, ensuring that the elastic member 30 abuts against the second sidewall 1112 during operation, thereby ensuring a stable and reliable connection between the treatment head 10 and the handle 20. Because second sidewall 1112 is perpendicular to the central axis of connecting shaft 11, it ensures that the elastic member 30 evenly distributes force when compressed, preventing deflection or deformation, and maintaining its normal operating state. This also makes it easier to position the elastic member 30 during assembly. This design ensures a more reliable connection, reduces the risk of accidental loosening of the treatment head 10 during use, and improves the user experience.

[0047] In an embodiment of the present invention, the elastic member 30 includes a finger contact spring 31 . The mounting groove 22 is formed around the inner circumference of the connecting hole 21 , and the finger contact spring 31 is disposed around the mounting groove 22 .

[0048] Specifically, the specific structure of the elastic member 30 can be selected according to actual needs, and can be set as a compression spring or an annular spring. Figure 2 In this embodiment, the elastic member 30 is configured as a finger spring 31. Accordingly, the mounting groove 22 is also configured as an annular groove, with the finger spring 31 encircling the mounting groove 22. This simplifies the assembly process, requiring only the finger spring 31 to be placed within the mounting groove 22, eliminating the need for complex positioning or securing steps. During use, the finger spring 31 provides elastic force by radially deforming. The annular groove provides sufficient space for the finger spring 31 to deform and limit its position, ensuring that the locking force is evenly distributed around the connecting shaft 11 of the treatment head 10, avoiding localized excessive pressure and thus improving the stability of the connection. The encircling finger spring 31 better accommodates the insertion and removal of the connecting shaft 11, ensuring that the treatment head 10 will not loosen or fall off due to vibration or external impact during use.

[0049] A specific embodiment is provided: when the treatment head 10 is inserted into the handle 20 under the action of external force, the connecting shaft 11 can easily cause the contact spring 31 to deform radially under the action of the introduction inclined surface 112, and can be inserted into the groove 111 of the connecting shaft 11. Because the first angle is greater than the second angle, the connecting shaft 11, under the action of the clamping force of the contact spring 31, relies on the first angle to provide a circumferential locking force toward the handle 20, so that the treatment head 10 remains on the handle 20; when the treatment head 10 is pulled out, a certain external force is applied to pull it out, and the contact spring 31 is radially deformed under the action of the first side wall 1111, and the treatment head 10 is smoothly pulled out.

[0050] The design of the finger spring 31 makes the insertion and removal of the treatment head 10 smoother, reduces the difficulty of operation, and improves the convenience of user use. The uniform locking force can ensure sufficient locking force, the connection is stable and easy to operate, and the plug-in and pull-out life is long.

[0051] In an embodiment of the present invention, a plurality of the mounting grooves 22 are provided. The plurality of mounting grooves 22 are spaced apart on the inner circumference of the connecting hole 21 , and an elastic member 30 is disposed in each of the mounting grooves 22 .

[0052] In detail, multiple mounting grooves 22 can be set. Multiple mounting grooves 22 can be set along the circumferential intervals of the connecting hole 21, or multiple mounting grooves 22 can be set along the axial intervals of the connecting hole 21. The mounting grooves 22 can also be designed into irregular shapes to meet specific space requirements. The specific layout method can be selected according to actual needs.

[0053] Correspondingly, each mounting groove 22 is provided with an elastic member 30, that is, multiple elastic members 30 are distributed at different positions of the connecting hole 21, which can ensure that the treatment head 10 is subjected to uniform locking force in all directions, thereby improving the stability of the connection.

[0054] The distributed elastic member 30 can provide a more reliable locking effect, can better adapt to the insertion and removal of the connecting shaft 11 of the treatment head 10, and the evenly distributed locking force can effectively prevent the treatment head 10 from accidentally falling off during use, thereby improving the safety of the device.

[0055] In an embodiment of the present invention, the elastic member 30 includes a ball (not shown) and a first spring (not shown), the ball is arranged in the mounting groove 22, and the first spring is arranged between the ball and the mounting groove 22.

[0056] It is worth noting that the first spring is connected to the ball and the mounting groove 22. When in use, the ball can provide a continuous outward thrust under the action of the first spring, and multiple balls can be inserted into the groove 111 to make the connection between the treatment head 10 and the handle 20 more secure and less likely to loosen.

[0057] The combination of the ball and the first spring can ensure uniform pressure distribution when the treatment head 10 is inserted or removed. The assembly process is relatively simple. When the treatment head 10 is inserted, the ball can temporarily retreat as the first spring is compressed. When the treatment head 10 is fully inserted, the ball returns to its original position under the action of the spring, providing locking force. This design makes the insertion and removal process smoother.

[0058] In an embodiment of the present invention, the elastic member 30 includes a second spring (not shown), which is disposed in the mounting groove 22 , and the axial direction of the second spring and the length direction of the mounting groove 22 both extend along the first direction.

[0059] Specifically, by extending the second spring in the axial direction and the length direction of the mounting groove 22 along the first direction, the mounting groove 22 here can be an arc groove or a rectangular groove, and the spring can be directly installed in the mounting groove 22. The assembly process is simple and quick, reducing the assembly difficulty and time required.

[0060] Multiple springs operate axially, providing stable elastic force and ensuring that the treatment tip 10 is securely fixed to the handle 20 after insertion. During insertion, the springs compress axially. Once the treatment tip 10 is fully inserted, the springs return to their original positions, providing a locking force. This axial spring operation reduces wear caused by lateral movement and extends the spring's service life.

[0061] In addition, if Figure 2 The handle 20 includes a front shell 25 and a rear shell 26. A first hole (not shown) is defined in the front shell 25, and a second hole (not shown) is defined in the rear shell 26. The front shell 25 and the rear shell 26 are connected so that the first hole and the second hole communicate with each other to form a connecting hole 21. A first notch (not shown) is defined along the circumference of the connecting wall of the rear shell 26, and a second notch (not shown) is defined along the circumference of the connecting wall of the front shell 25. The first notch and the second notch together form a mounting slot 22, which facilitates the installation of the elastic member 30. The front shell 25 and the rear shell 26 are fixedly connected by bolts for easy assembly and disassembly.

[0062] In an embodiment of the present utility model, the handle 20 is further provided with a plug-in column 23 located in the connecting hole 21, and a first conveying channel 24 is provided on the plug-in column 23. A plug-in hole 113 is provided on the connecting shaft 11, and a second conveying channel 114 is provided on the bottom wall of the plug-in hole 113. The connecting shaft 11 is inserted into the connecting hole 21, and the plug-in column 23 is inserted into the plug-in hole 113, so that the first conveying channel 24 is connected to the second conveying channel 114.

[0063] In detail, the design of the plug-in column 23 and the plug-in hole 113 makes the insertion process faster and more accurate, improves the connection efficiency, simplifies the connection between the treatment head 10 and the handle 20, and allows the two to automatically align with the delivery channel through the cooperation of the plug-in column 23 and the plug-in hole 113, reducing the need for manual alignment.

[0064] During use, the user can quickly complete the installation and disassembly of the treatment head 10, which reduces the difficulty of operation, improves the user experience, and ensures the correct alignment of the first delivery channel 24 and the second delivery channel 114: the first delivery channel 24 and the second delivery channel 114 are connected so that the refrigerant can be smoothly transmitted from the handle 20 to the treatment head 10, ensuring the continuity and effectiveness of the treatment process.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
