[0033] The utility model provides a treatment handle 1.

[0034] Combine Figure 1 、 Figure 2 、 Figure 9 as well as Figure 10As shown, in one embodiment of the present invention, the treatment handle 1 includes a shell 10, a bracket 40, an unlocking assembly 20 and a first elastic member 30; the bracket 40 is detachably connected to the shell 10; the unlocking assembly 20 is movably mounted on the shell 10, and the unlocking assembly 20 is suitable for moving toward or away from the bracket 40; the first elastic member 30 is respectively connected to the unlocking assembly 20 and the bracket 40, and the first elastic member 30 is used to reset the unlocking assembly 20 after moving relative to the bracket 40.

[0035] In this embodiment, the housing 10 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are detachably connected by means of snap-fitting, plug-in connection, etc., to facilitate installation and replacement of components within the treatment handle 1. The housing 10 can be made of materials such as plastic, metal, or ceramic to ensure its durability and stability.

[0036] The bracket 40 is disposed inside the housing 10 and is detachably connected to the inside of the housing 10 by means of a snap connection, a screw connection, or a magnetic attraction, so as to facilitate quick disassembly and assembly by the user.

[0037] The unlocking assembly 20 is movably mounted on the housing 10. It can be moved relative to the housing 10 using a slider, rotary knob, or other mechanism to accommodate different usage scenarios and user preferences. When the unlocking assembly 20 is driven toward or away from the bracket 40, the treatment handle 1 and the treatment head are locked and unlocked.

[0038] The first elastic member 30 can be an elastic structure such as a spring, a rubber pad, or a spring, and is elastically connected to the unlocking assembly 20 and the bracket 40 respectively, providing a reset force for the unlocking assembly 20 after movement, ensuring that the unlocking assembly 20 can quickly return to its initial position for the next operation.

[0039] Since the bracket 40 and the unlocking assembly 20 are both detachably connected to the housing 10, when assembling the treatment handle 1, the two ends of the first elastic member 30 can be first connected to the bracket 40 and the unlocking assembly 20 respectively, and then the module formed by assembling the unlocking assembly 20 and the bracket 40 can be installed in the housing 10 to ensure the assembly accuracy of the first elastic member 30, the bracket 40, and the unlocking assembly 20. Of course, the bracket 40 can also be installed in the housing 10 first, and then the first elastic member 30 and the unlocking assembly 20 can be assembled into the housing 10 in sequence to improve the convenience of assembling the bracket 40. Therefore, the above-mentioned structural design of the present application provides more flexibility and convenience for the assembly of the various components in the treatment handle 1. The user can choose the appropriate assembly order according to the requirements of the structural size, shape, processing accuracy, matching method and assembly accuracy during actual assembly.

[0040] In addition, through the above-mentioned structural design, the present application allows the user to compress the first elastic member 30 through a simple pressing action, thereby driving the unlocking component 20 to quickly unlock the treatment head and the treatment handle 1. This design simplifies the disassembly steps of the treatment handle 1, making the replacement of accessories and instrument maintenance faster and more convenient, thereby improving the user's operating experience.

[0041] Combine Figure 2 and Figure 8 As shown, in one embodiment of the present invention, the treatment handle 1 further includes a mounting bracket 50 , which is detachably connected to the housing 10 and presses the bracket 40 onto the surface of the housing 10 .

[0042] In this embodiment, the mounting bracket 50 serves to fix the bracket 40 and to support and install other components. Since the bracket 40 is used to cooperate with the unlocking component 20 and the first elastic member 30 to achieve the unlocking function, the unlocking component 20 and the bracket 40 are generally arranged near the side of the housing 10 to facilitate the user to press and unlock. Figure 8 As shown, the present application places a mounting bracket 50 in the center of the housing 10 to facilitate assembly of the various components. The bracket 40 is placed on one side of the mounting bracket 50. A pressing block 61 extends from the mounting bracket 50 toward the side of the bracket 40. The pressing block 61 presses against the surface of the bracket 40 to improve the stability of the bracket 40. Furthermore, the pressing portion of the mounting bracket 50 can be designed as a flexible or size-adjustable pressing mechanism to accommodate the pressing of brackets 40 of different sizes.

[0043] The mounting bracket 50 can be connected to the housing 10 using a snap-on, threaded, or magnetic connection, facilitating quick disassembly and assembly. Multiple mounting holes 121 are provided on the surface of the mounting bracket 50, through which the various components of the treatment handle 1 can be secured to the mounting bracket 50. Compared to solutions that directly attach the handle to the housing 10, this design allows the components to be assembled into a single unit with the mounting bracket 50 before the entire structure is secured within the housing 10, improving assembly convenience.

[0044] Combine Figures 2 to 6 As shown, in one embodiment of the present invention, the treatment handle 1 further includes a cover plate 70 , which is detachably connected to a side of the mounting frame 50 facing away from the bracket 40 , and a light strip 71 is provided on the surface of the cover plate 70 .

[0045] In this embodiment, the portion of the upper housing 11 corresponding to the cover 70 is made of a transparent or translucent material to ensure that light from the light strip 71 can be emitted through the upper housing 11. The light strip 71 can be used to display the operating status of the therapeutic device to facilitate user operation and also creates an ambient lighting effect, enhancing the aesthetics of the therapeutic handle 1.

[0046] The cover plate 70 can be connected to the mounting holes 121 provided on the mounting frame 50 via threaded fasteners, allowing for a removable connection between the cover plate 70 and the mounting frame 50. A driver is positioned between the cover plate 70 and the mounting frame 50, clamped and secured within the housing 10 by the cover plate 70 and the mounting frame 50, enhancing the driver's stability. This sequential arrangement of components along the axis of the treatment handle 1 reduces interference between different components in the radial and circumferential directions of the treatment handle 1, facilitating assembly.

[0047] Combine Figure 2 、 Figure 4 and Figure 9 As shown, in one embodiment of the present invention, the treatment handle 1 also includes a transmission shaft 80, and the shell 10 is provided with a mounting hole 121. The transmission shaft 80 is partially located in the shell 10, and one end passes through the mounting hole 121 for driving the connection treatment head. The transmission shaft 80 is movably arranged on the side of the mounting frame 50 facing the shell 10, and is limited between the mounting frame 50 and the shell 10.

[0048] In this embodiment, the driving member in the treatment handle 1 drives the transducer in the treatment head via the transmission shaft 80, thereby causing the transducer to move and adjust the focal length. The portion of the transmission shaft 80 located within the housing 10 is used to connect to the driving member, and the portion extending from the mounting hole 121 is used to drive the transducer connected to the treatment head. Therefore, the transmission shaft 80 is configured to be movable relative to the housing 10. Specifically, the transmission shaft 80 can be clearance-matched with the hole wall of the mounting hole 121, or bearings can be provided between the transmission shaft 80 and the mounting hole 121 to enable rotation of the transmission shaft 80. A limiting groove is provided on the side of the mounting bracket 50 facing the transmission shaft 80. When the mounting bracket 50 is installed on the inner wall of the housing 10, the limiting groove cover is provided on the outside of the transmission shaft 80 to limit the movement of the transmission shaft 80 in the horizontal and vertical directions, thereby improving the stability of the transmission shaft 80 during rotation.

[0049] Further, such as Figure 8 As shown, a driving hole 62 is opened on the surface of the mounting frame 50, and the driving member is installed on the mounting frame 50. The output shaft of the driving member passes through the driving hole 62 and is driven and connected to the transmission shaft 80. The mounting frame 50 not only fixes the driving member and the transmission shaft 80, but also improves the stability of the driving connection between the driving member and the transmission shaft 80.

[0050] Combine Figure 9 As shown, in one embodiment of the present invention, a transmission groove is provided on the end surface of the transmission shaft 80 facing the mounting bracket 50 , and a second elastic member 81 is provided in the transmission groove. The second elastic member 81 is used to achieve the reset of the transmission shaft 80 when it moves relative to the mounting bracket 50 .

[0051] In this embodiment, a transmission slot is defined on the end surface of the drive shaft 80 facing the mounting bracket 50, within which a second elastic member 81 is disposed. The second elastic member 81 is a spring, and the shape and size of the transmission slot are adapted to the spring. The spring is embedded within the transmission slot, which limits the deformation of the spring and improves the stability of the drive shaft 80 during reset relative to the mounting bracket 50. The output shaft of the driver is inserted into the transmission slot and abuts against the spring. In other embodiments, the spring may be partially embedded within the transmission slot, and the second elastic member 81 may alternatively be an elastic structure such as a spring sheet or rubber pad.

[0052] Combine Figure 9 As shown, in one embodiment of the present invention, the treatment handle 1 also includes a sliding sleeve 82, which is sleeved on the outside of the transmission shaft 80, and the transmission shaft 80 slides with the sliding sleeve 82 along its axial direction, and the mounting frame 50 is crimped to the sliding sleeve 82.

[0053] In this embodiment, the sliding sleeve 82 can be made of metal or plastic and is sleeved onto the outside of the transmission shaft 80, so that the transmission shaft 80 and the sliding sleeve 82 slide together and can slide axially and rotate circumferentially relative to the housing 10. The inner diameter of the sliding sleeve 82 closely matches the outer diameter of the transmission shaft 80 to ensure the stability of the sliding sleeve 82 as it slides on the transmission shaft 80. The outer surface of the sliding sleeve 82 can be designed with grooves or protrusions to increase friction with the mounting bracket 50. A sealing ring is sleeved around the outer circumference of the transmission shaft 80, which closely matches the inner wall of the housing 10 or the inner wall of the sliding sleeve 82 to enhance the waterproofing of the treatment handle 1. The mounting bracket 50 is pressed against the sliding sleeve 82 to secure the sliding sleeve 82 to the inner wall of the housing 10, thereby improving the stability of the transmission shaft 80 during rotation.

[0054] Combine Figures 2 to 4 、 Figure 7 as well as Figure 8 As shown, in one embodiment of the present invention, the treatment handle 1 further includes a motor 60 , which is mounted on the mounting frame 50 .

[0055] In this embodiment, connection holes are provided on the surface of the mounting frame 50 and the surface of the motor 60. Connectors are sequentially passed through the connection holes on the motor 60 and the mounting frame 50 to securely connect the motor 60 to the mounting frame 50. A plurality of positioning blocks 63 are provided on the surface of the mounting frame 50. The plurality of positioning blocks 63 are spaced apart along the circumference of the mounting frame 50. When the motor 60 is mounted on the mounting frame 50, the plurality of positioning blocks 63 are respectively attached to the circumference of the motor 60, thereby positioning the assembly of the motor 60, so that the connection holes on the motor 60 and the connection holes on the mounting frame 50 are precisely aligned. At the same time, the output shaft of the motor 60 is precisely aligned with the drive hole 62 on the mounting frame 50, thereby improving the efficiency and accuracy of the assembly of the motor 60 and the mounting frame 50.

[0056] Combine Figures 8 to 10 As shown, in one embodiment of the present invention, the housing 10 is provided with a positioning hole, and the bracket 40 is provided with a positioning post 41 . The positioning post 41 is inserted into the positioning hole so that the bracket 40 and the housing 10 are plugged and matched.

[0057] In this embodiment, the positioning posts 41 and the positioning holes can be designed in circular, square, or other shapes. The cooperation between the positioning posts 41 and the positioning holes improves the assembly efficiency and assembly precision of the bracket 40 and the housing 10, allowing the first elastic member 30 and the unlocking assembly 20 to be precisely assembled with the housing 10 and the bracket 40. Furthermore, at least two positioning posts 41 and two positioning holes are provided, each of which cooperates with a positioning hole to prevent rotation between the bracket 40 and the housing 10.

[0058] A latch 42 is also provided on one side of the bracket 40. When the first elastic member 30 is a spring, one end of the spring is sleeved on the latch 42 to ensure the stability of the spring during deformation, while also improving the convenience of assembling and positioning the spring and the bracket 40.

[0059] Combine Figure 2 、 Figure 9 and Figure 10 As shown, in one embodiment of the present invention, a button hole 122 is opened on the side wall of the shell 10, and the unlocking component 20 includes a detachably connected button 21 and a limit block 22. The button 21 is partially inserted into the button hole 122 and exposed on the surface of the shell 10. The limit block 22 is used to drive the connection to the treatment head. The first elastic member 30 is respectively connected to the button 21 and the bracket 40, and is used to reset the button 21 after movement.

[0060] In this embodiment, since the unlocking assembly 20 needs to cooperate with the first elastic member 30 and the bracket 40 to achieve unlocking and resetting, and also needs to align with the button hole 122 to facilitate pressing to unlock, and also needs to drive the treatment head to move to unlock, the unlocking assembly 20 is designed to be detachably connected to the button 21 and the limit block 22, so that the unlocking assembly 20 can cooperate with the button hole 122, the first elastic member 30 and the treatment head. The button hole 122 is provided on one side of the treatment handle 1 to facilitate the user to press the button 21. The button 21 and the limit block 22 can be connected by means of threaded connection, snap connection, plug-in connection, or by a connector. For example, threaded connection holes are provided on the surface of the button 21 and the limit block 22, and the button 21 and the limit block 22 are detachably connected in sequence by bolts to facilitate user replacement or maintenance.
