[0063] In the embodiment, referring to Figure 7 , the fixing portion 20 is arranged with a plurality of grooves 23 in the length direction, when the locking portion 30 locks the fixing portion 20, the locking portion 30 abuts in the groove 23, so as to limit the continuous movement of the fixing portion 20. Specifically, the second mounting area of the fixing portion 20 is a circular column structure, and the second mounting area is arranged with a plurality of grooves 23 in the length direction, the groove 23 can be an arc-shaped groove or a rectangular groove, when the locking portion 30 abuts on the surface of the fixing portion 20 in the radial direction of the mounting hole 11, the locking portion 30 is inserted into the groove 23, so as to limit the continuous movement of the fixing portion 20. Compared with the flat surface, the nesting cooperation of the groove 23 and the locking portion 30 can improve the locking precision of the locking portion 30, thereby improving the user's experience.

[0064] In this embodiment, the groove 23 is a conical tooth groove. Figure 7 As shown, the groove 23 is a tapered tooth groove arranged downwardly along the height direction of the fixing portion 20. When the fixing portion 20 moves downward, it can provide downward pulling force on the tensioner 202, thereby keeping the tensioner 202 in a tensioned state and achieving scalp tension. In this embodiment, the locking portion 30 abuts and provides a force to prevent the fixing portion 20 from retracting, thereby maintaining the tensioner 202 in a continuously tensioned state, thereby ensuring that the scalp is always in a taut state.

[0065] In this embodiment, the locking portion 30 is disposed in the mounting portion 10 and away from the mounting plate 201. Figure 4 and Figure 5 Along the height direction of the mounting portion 10, the locking portion 30 is arranged inside the mounting portion 10 and close to the side of the mounting portion 10 away from the mounting plate 201. The mounting portion 10 and the mounting plate 201 are connected by a bolt assembly, and the locking portion 30 is arranged away from the mounting plate 201, so that when the operator operates the locking portion 30 to lock the fixing portion 20, interference between the operator's hand and the mounting plate 201 can be avoided.

[0066] In this embodiment, see Figure 4 and Figure 5 An accommodating groove 12 is provided in the mounting portion 10 along the radial direction of the mounting hole 11 , the locking portion 30 is movably connected in the accommodating groove 12 , and one end of the locking portion 30 extends out of the mounting portion 10 .

[0067] Specifically, the receiving groove 12 extends radially along the mounting hole 11 and communicates with the mounting hole 11. One end of the locking portion 30 extends into the receiving groove 12 and abuts against the surface of the fixing portion 20 located within the mounting hole 11 along the radial direction of the mounting hole 11, thereby locking the fixing portion 20. When the locking portion 30 is located within the receiving groove 12, one end of the locking portion 30 always extends out of the mounting portion 10, making it easier for an operator to operate the locking portion 30, thereby effectively locking or unlocking the fixing portion 20.

[0068] In addition, the accommodating groove 12 can also extend to the opposite sides of the mounting hole 11. For example, the mounting portion 10 has a first side wall and a second side wall relative to each other. The accommodating groove 12 can penetrate the mounting hole 11 from the first side wall of the mounting portion 10 along the radial direction of the mounting hole 11, and extend to the second side wall of the mounting portion 10, so that when the locking portion 30 is located in the accommodating groove 12, it can correspond to the opposite side walls of the fixing portion 20. In actual use, any opposite side wall or opposite side walls of the fixing portion 20 can be locked to suit different usage environments.

[0069] In this embodiment, see Figure 5The locking portion 30 comprises a locking piece 31, an elastic piece 32 and two push rods 33. The locking piece 31 is sleeved on the outer circumferential side of the fixing portion 20. The two push rods 33 are respectively located on the opposite sides of the locking piece 31 and are arranged along the extension direction of the accommodating groove 12. The elastic piece 32 is arranged on the groove bottom of the accommodating groove 12 and is connected with one of the push rods 33 close to the groove bottom of the accommodating groove 12. The elastic piece 32 is used to provide the action force for the movement of the locking piece 31 along the radial direction of the mounting hole 11.

[0070] Specifically, the locking piece 31 is a circular ring sleeved on the fixing portion 20. The locking piece 31 is arranged along the radial direction of the mounting hole 11 and can move relative to the radial direction of the mounting hole 11. The profile of the part of the accommodating groove 12 corresponding to the locking piece 31 is the same as the locking piece 31, that is, the accommodating groove 12 comprises a circular ring segment and two rod segments arranged on the opposite sides of the circular ring segment. It can be understood that the size of the circular ring segment is larger than the size of the locking piece 31, so that the locking piece 31 can move freely in the accommodating groove 12 and will not be interfered by the accommodating groove 12. The circular ring segment is annularly arranged on the outer circumferential side of the mounting hole 11. When the second fixing area of the fixing portion 20 extends into the mounting hole 11, the locking piece 31 is sleeved on the outer circumferential side of the fixing portion 20. It is worth mentioning that in this embodiment, during the process of sliding along the transverse direction of the accommodating groove 12, the locking piece 31 can abut against the two side walls of the fixing portion 20 perpendicular to the length direction of the accommodating groove 12. In this way, the two opposite side walls of the fixing portion 20 can provide guidance during the sliding process of the locking piece 31 along the accommodating groove 12, so as to ensure that the locking piece 31 has only one sliding posture, thereby improving the locking performance of the locking piece 31.

[0071] Further, the groove bottom of the accommodating groove 12 is provided with the elastic piece 32. The elastic piece 32 can be a spring, a tension spring or a torsion spring, which is not limited here. The purpose is to provide the action force for the movement of the locking piece 31 along the radial direction of the mounting hole 11. The push rod 33 can be automatically reset by the elastic piece 32, thereby reducing the operation steps and improving the convenience of operation.

[0072] When the elastic piece 32 is a spring, the working principle is as follows:

[0073] The spring is sleeved on the push rod 33 close to the groove bottom of the accommodating groove 12. One end of the spring abuts against the side wall of the locking piece 31 close to the groove bottom of the accommodating groove 12, and the other end of the spring abuts against the groove bottom of the accommodating groove 12. The locking piece 31 abuts against the surface of the fixing portion 20 located in the mounting hole 11 by the action force provided by the spring, so as to realize the locking of the fixing portion 20. When it is necessary to unlock, since the push rod 33 arranged on the other side of the locking piece 31 always extends out of the mounting portion 10, that is, out of the accommodating groove 12, the operator can drive the spring to be compressed by pressing the push rod 33 with the hand, so as to separate the locking piece 31 from the surface of the fixing portion 20, thereby realizing the unlocking function.

[0074] It can be understood that when the elastic member 32 is a tension spring, because the tension spring is pulled towards the groove bottom of the accommodating groove 12 to pull the locking member 31, the side of the locking member 31 is converted to the other side of the fixed part 20, and when the locking member 31 is unlocked, the push rod 33 is pulled to move the locking member 31, thereby achieving the unlocking function, which will not be described in detail here.

[0075] In the embodiment, referring to Figs. 1 to 3, Figure 4 and Figure 5 The mounting part 10 is further provided with a cover plate 13, the accommodating groove 12 is recessed from the end of the mounting part 10 away from the mounting plate 201, and the cover plate 13 is also provided with a circular ring segment and a rod segment corresponding to the accommodating groove 12, so as to close the top of the accommodating groove 12 after the cover plate 13 is arranged on the accommodating groove 12 and to accommodate the locking part 30 together with the accommodating groove 12. Preferably, the cover plate 13 is connected with the accommodating groove 12 through a bolt assembly, but is not limited thereto.

[0076] In other embodiments, the locking part 30 can be a screw, and only a threaded hole through which the mounting hole 11 is communicated needs to be formed in the side wall of the mounting part 10. When the locking part 30 is locked, the end of the screw is abutted against the surface of the fixed part 20 in the mounting hole 11 by screwing the screw, and when the locking part 30 is unlocked, the end of the screw is away from the fixed part 20 by unscrewing the screw.

[0077] In the embodiment, because the fixed part 20 is provided with a plurality of grooves 23 arranged at intervals, the grooves 23 are tapered tooth grooves, and a protrusion 311 can be preferably arranged on the side of the locking member 31 corresponding to the groove 23. The protrusion 311 is a tapered structure matched with the profile of the tapered tooth groove. When the locking member 31 is abutted against the groove 23 of the fixed part 20, the protrusion 311 and the groove 23 are nested to further improve the locking effect.
