[0059] Combination Figures 3 to 7 As shown, in some embodiments of the present application, the locking assembly 30 includes a locking member 31, which is rotatably connected to the shell assembly 10, and the locking member 31 includes a first protruding end 311 and a second protruding end 312. The locking member 31 is configured such that when the first magnetic member 13 and the second magnetic member 23 are magnetically attracted to each other, the first protruding end 311 is clamped between the shell assembly 10 and the massage head assembly 20, and the second protruding end 312 is clamped with the massage head assembly 20.

[0060] In some embodiments of the present application, the locking member 31 is provided with a mounting hole 314, the rotating shaft 32 is passed through the mounting hole 314, and the two ends of the rotating shaft 32 are respectively connected to the first housing portion 11, so as to support the rotation of the locking member 31. The first housing portion 11 forms a receiving groove 111 on the side facing the massage head assembly 20, and part of the massage head assembly 20 is inserted into the receiving groove 111. Among them, the locking member 31 is provided with a first protruding end 311 and a second protruding end 312, and the side wall of the first housing portion 11 is provided with an opening, and the first protruding end 311 and the second protruding end 312 can extend into the receiving groove 111 through the opening on the side wall of the first housing portion 11. When the massage head assembly 20 is inserted into the receiving groove 111, the first magnetic attraction member 13 and the second magnetic attraction member 23 are attracted. The first extension end 311 is sandwiched between the bottom of the base 211 and the inner bottom surface of the receiving groove 111, and the second extension end 312 is engaged with the recessed portion of the outer peripheral surface of the base 211, thereby locking and connecting the base 211 and the first housing portion 11, that is, locking and connecting the massage head assembly 20 and the housing assembly 10. When the massage head assembly 20 needs to be removed from the housing assembly 10, the massage head assembly 20 can be removed from the housing assembly 10 by sliding the massage head assembly 20 along the outer peripheral surface of the base 211. Figure 3 The locking piece is rotated counterclockwise at the position shown in the figure to separate the second extension end 312 from the recessed portion of the outer peripheral surface of the base 211, thereby releasing the clamping connection between the second extension end 312 and the base 211. At the same time, the first extension end 311 lifts up the base 211 during the counterclockwise rotation, thereby releasing the magnetic connection between the first magnetic element 13 and the second magnetic element 23, thereby facilitating the disassembly of the massage head assembly 20.

[0061] Combination Figures 3 to 7 As shown, in some embodiments of the present application, the locking assembly 30 also includes a spring 33, and the locking member 31 also includes a third protruding end 313. The first protruding end 311, the second protruding end 312 and the third protruding end 313 are respectively arranged at angles along the rotation direction of the locking member 31. The spring 33 is clamped between the third protruding end 313 and the supporting structure in the shell assembly 10. The spring 33 is configured to drive the second protruding end 312 to engage with the massage head assembly 20.

[0062] In some embodiments of the present application, a support structure is provided inside the second housing portion 12, and the support structure may include a support plate 121. The support plate 121 divides the inside of the second housing portion 12 into two parts, one of which is used to accommodate the battery 14 and the first circuit board 15, and the other part is used to accommodate the locking member 31 and the spring 33. The spring 33 is sandwiched between the support plate 121 and the third extension end 313. To facilitate the fixing of the spring 33, a support column 315 is provided on the surface of the third extension end 313 facing the support plate 121, one end of the spring 33 is sleeved on the support column 315, and the other end of the spring 33 abuts against the support plate 121.

[0063] When the massage head assembly 20 needs to be disassembled, the third extension end 313 is pressed in the direction of the spring 33, and the locking member 31 rotates counterclockwise, so that the second extension end 312 is separated from the recessed portion of the outer peripheral surface of the base 211, so that the first extension end 311 lifts the base 211, and the massage head assembly 20 can be disassembled. At the same time, in the process of pressing the third extension end 313, the spring 33 is compressed and deformed and has elastic force, thereby improving the user's touch when pressing. When the massage head assembly 20 needs to be assembled to the housing assembly 10, the third extension end 313 is pressed in the direction of the spring 33, and the locking member 31 rotates counterclockwise, so that the base 211 is plugged into the receiving groove 111. When the first magnetic attraction member 13 and the second magnetic attraction member 23 are attracted, and the PIN pin connector 41 is plugged into the socket 151, the third extension end 313 is no longer pressed. Since the spring 33 is compressed and deformed and has elastic force during the process of pressing the third extending end 313, the third extending end 313 moves in a direction away from the spring 33 under the action of the elastic force of the spring 33, and at the same time, the first extending end 311 and the second extending end 312 rotate clockwise, so that the second extending end 312 is engaged with the recessed portion of the outer peripheral surface of the base 211, and the first extending end 311 is clamped between the bottom of the base 211 and the inner bottom surface of the accommodating groove 111.

[0064] Combination Figures 1 to 4 As shown, in some embodiments of the present application, in order to facilitate pressing the third protruding end 313, a pressing piece 50 is provided on the side of the second shell portion 12, and part of the pressing piece 50 is inserted into the interior of the second shell portion 12 and abuts against the third protruding end 313. By squeezing the pressing piece 50, the third protruding end 313 can be pressed.

[0065] Combination Figures 1 to 4 As shown, in some embodiments of the present application, the scraping instrument 1 further includes a mounting cap 70, which can be covered on the outside of the massage head assembly 20, so that when the scraping instrument 1 is in a non-massage state, the massage head 22 assembly can be protected by the mounting cap 70 to reduce pollution. The mounting cap 70 can be snapped with the outer side surface of the mounting seat 212.

[0066] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
