[0034] Further, the length adjusting mechanism comprises a first circular groove respectively formed on the two arc-shaped housings 1 in any one of the fixing rings, a first long hole formed on the two arc-shaped housings 1 in any one of the fixing rings, the two first long holes being in communication with the two first circular grooves, a first threaded rod 16 being rotationally installed in the first long hole, an end of the first threaded rod 16 close to the first circular groove being transversely provided with a second circular groove, a first limiting rod 15 being slidingly installed in the second circular groove, the first threaded rod 16 being circumferentially provided with a plurality of first grooves along the second circular groove, the first grooves being in communication with the second circular groove, a plurality of insertion slots being circumferentially formed on the first limiting rod 15, the plurality of insertion slots being correspondingly arranged with the plurality of first grooves, a first limiting block 21 being rotationally installed in the first groove, an end of the first limiting block 21 being matched with the insertion slot, an end of the first limiting block 21 away from the first limiting rod 15 being fixedly connected with a third spring 32, an end of the third spring 32 being fixedly connected with an inner wall of the first groove, an end of the first limiting rod 15 away from the first circular groove being fixedly connected with a first tension spring 33, an end of the first tension spring 33 being fixedly connected with an inner wall of the second circular groove, the insertion slot being located between the first tension spring 33 and the first limiting block 21, an end of the first limiting block 21 being slidingly matched with the first limiting rod 15 away from the first tension spring 33, an end of the first threaded rod 16 away from the first circular groove extending into the arc-shaped housing 1 in the other fixing ring and being threadedly matched with the arc-shaped housing 1 in the other fixing ring, an end of the first limiting rod 15 close to the first circular groove being fixedly installed with a third knob 14, the third knob 14 being abutted with the first circular groove.

[0035] In use, the third knob 14 in the first circular groove is pulled outward, the first limiting rod 15 slides outward in the second circular groove of the first threaded rod 16, when the insertion slot slides to the position of the first limiting block 21, the first limiting rod 15 is clamped into the insertion slot under the pressure of the third spring 32, at this time, the first limiting block 21 prevents the first limiting rod 15 from being pulled outward, thereby reminding the medical staff that the first limiting rod 15 has been clamped with the first threaded rod 16, then the third knob 14 is rotated to drive the first threaded rod 16 to rotate, thereby the relative position between the two fixing rings can be adjusted; after adjustment, the third knob 14 is loosened, the first limiting rod 15 makes the third knob 14 automatically return to the state of abutting with the inner wall of the first circular groove under the tension of the first tension spring 33, thereby the adjustment of the relative position of the fixing rings is completed.

[0036] In addition, the third knob 14 is automatically retracted into the first circular groove under the pulling force of the first tension spring 33 when not in use, so that the third knob 14 does not protrude on the arc-shaped shell 1 when not in use, which can effectively avoid the collision between the third knob 14 and external objects when the patient carries the arc-shaped shell 1 to move, thereby effectively avoiding damage to the third knob 14 due to collision, and also avoiding the situation that the patient is secondarily injured due to collision.

[0037] Further, the pressure adjusting mechanism comprises a second groove opened on the arc-shaped outer wall of the arc-shaped shell 1, a second shell 11 fixedly installed in the second groove, a second threaded rod 22 installed in the second shell 11, one end of the second threaded rod 22 penetrating through the second shell 11 and in limited rotary cooperation with the second shell 11, a second knob 12 fixedly installed on the end of the second threaded rod 22 located outside the second shell 11, the other end of the second threaded rod 22 in rotary cooperation with the inner wall of the second shell 11, a first sliding block 23 threadedly cooperating with the second threaded rod 22, the side wall of the first sliding block 23 in limited sliding cooperation with the inner wall of the second shell 11, a second connecting hole 25 and a first connecting hole 24 respectively opened on the end of the second shell 11 away from the second knob 12, the ends of the second connecting hole 25 and the first connecting hole 24 both communicating with the first shell 10, hydraulic oil being arranged in the second shell 11, the first shell 10 and the arc-shaped bag 31, the end of the second connecting hole 25 being located between the second knob 12 and the end of the first connecting hole 24, and the end of the second connecting hole 25 being located in the middle of the first shell 10, a second sliding block 27 slidingly cooperating with the first shell 10, the first shell 10 being divided into a first chamber and a second chamber by the second sliding block 27 along the horizontal direction, the end of the first connecting hole 24 communicating with the second chamber, second springs 26 fixedly installed on both ends of the second sliding block 27, the ends of the two second springs 26 being fixedly connected with the inner wall of the first chamber and the inner wall of the second chamber respectively, a third connecting hole 28 opened in the second sliding block 27, one end of the third connecting hole 28 corresponding to the end of the second connecting hole 25, the other end of the third connecting hole 28 communicating with the first chamber, a first connecting pipe 29 penetrating through the first shell 10 and fixedly connected with the first shell 10, the first connecting pipe 29 communicating with the first chamber, and the end of the first connecting pipe 29 communicating with the arc-shaped bag 31.

[0038] In use, the second knob 12 is rotated, which drives the second threaded rod 22 to rotate, and the first sliding block 23 moves in the second shell 11, thereby extruding the hydraulic oil in the second shell 11, increasing the pressure of the hydraulic oil in the second shell 11, and making the pressure of the hydraulic oil in the second shell 11 equal to the pressure of the hydraulic oil in the arc-shaped bladder 31; at this time, the hydraulic oil in the arc-shaped bladder 31 can give pressure to the local muscle tissue of the patient; when the local muscle tissue pressure of the patient decreases, the pressure in the first chamber will decrease accordingly, since the pressure in the second shell 11 does not change, and the pressure of the hydraulic oil in the second shell 11 is connected through the first connecting hole 24 and the second chamber, at this time, the pressure of the second chamber is greater than the pressure in the first chamber, and the hydraulic oil in the second chamber will push the second sliding block 27 to move leftwards, when the second sliding block 27 moves leftward to the third connecting hole 28 and the second connecting hole 25 are communicated, the hydraulic oil in the second shell 11 will flow into the first chamber through the third connecting hole 28 and the second connecting hole 25, thereby the pressure in the first chamber and the second chamber is leveled again, and the arc-shaped bladder 31 can be automatically pressure compensated; when the pressure in the first chamber gradually increases, the second sliding block 27 will be pushed to move rightward again, at this time, the second sliding block 27 will return to the initial position under the joint action of the second spring 26 and the hydraulic oil pressure, and the third connecting hole 28 and the second connecting hole 25 will be disconnected, thereby the automatic adjustment of the pressure of the local muscle tissue of the patient is completed.
