Compared with the prior art, the applicator wearing device 1 can be worn by a patient, and the applicator 6 is fixedly installed through the applicator wearing device 1. Wherein, the arc slide rail 3a on the applicator wearing device 1 can adjust the positioning tube 6b of the applicator 6, thereby adjusting the state of the applicator part 6a and leading the applicator 6 to be fixedly installed in a way of being more attached to the affected part of the patient. In addition, the portion of wearing 2 both the patient of being convenient for removes, and the patient of being convenient for carries and executes source ware 6 and remove, can shield patient's privacy position (affected part) again better, is favorable to promoting patient's treatment and experiences.

Second embodiment

According to the first embodiment, the positioning and fixing member 3b can slide along the house-type arc-shaped sliding rail 3a to adjust the applicator 6, but if the positioning and fixing member 3b moves during the treatment process, the applicator 6a may be displaced relative to the affected part, which is not favorable for the treatment.

In order to solve the above problem, in the second embodiment of the present application, referring to fig. 5 to 9, at least one side of the positioning and fixing member 3b is provided with a sliding groove 3b1, and the sliding groove 3b1 is slidably sleeved on the arc-shaped sliding rail 3a, and the sliding groove 3b1 is provided with a sliding locking member 3b 2.

Specifically, the groove width of the ring groove of the positioning and fixing member 3b is larger than the thickness of the arc-shaped slide rail 3a, so that the positioning and fixing member 3b can smoothly and continuously slide along the arc-shaped slide rail 3 a. Moreover, the surfaces of the arc-shaped slide rails 3a, which are in contact with the slide grooves 3b1, are smooth surfaces (e.g., metal surfaces) to reduce the sliding friction between the positioning fixing pieces 3 b.

In the preferred embodiment of the present application, the groove wall of the sliding groove 3b1 is provided with a mounting position (not shown) for a ball (not shown) to mount the ball between the groove wall and the sliding groove 3b1, so that the sliding friction is converted into rolling friction when the positioning fixing member 3b slides, and the resistance of the positioning fixing member 3b during sliding is further reduced.

In other embodiments of the present application, the sliding groove 3b1 may be disposed on the arc-shaped sliding rail 3a, and a part of the positioning fastener 3b is embedded in the sliding groove 3b1, so as to realize the sliding fit between the positioning fastener 3b and the arc-shaped sliding rail 3 a.

After the positioning fixing piece 3b is slid to the target position, the position of the positioning fixing piece 3b on the arc-shaped slide rail 3a can be fixed by sliding the locking piece 3b 2. In this embodiment, the slide lock 3b2 can fix the positioning fixture 3b to the slide groove 3b1 through the groove wall.

Specifically, in one embodiment of the present application, referring to fig. 5, the sliding lock 3b2 is a locking bolt 3b21, a screw hole 3b4 is provided on the groove wall, and the locking bolt 3b21 passes through the screw hole 3b4 to contact the arc-shaped sliding rail 3 a. When the positioning fastener 3b slides, the locking bolt 3b21 is in an unlocked state, that is, the front end (the end penetrating through the screw hole 3b 4) of the locking bolt 3b21 does not abut against or press against the arc-shaped slide rail 3a, that is, no force acts between the front end of the locking bolt 3b21 and the arc-shaped slide rail 3a, and the arc-shaped slide rail 3a and the positioning fastener 3b can slide relatively. When the positioning fixing piece 3b reaches the target position, the locking bolt 3b21 is tightened to be in a fastening state, and the front end of the locking bolt 3b21 abuts against or presses the arc-shaped slide rail 3a, so that the movement or the movement tendency between the positioning fixing piece 3b and the arc-shaped slide rail 3a is prevented.

Specifically, the stopper 3b3 is used to increase the locking effect of the slide lock 3b2, and may generally increase the positive pressure between the slide lock 3b2 and the curved slide rail 3a or the friction between the slide lock 3b2 and the curved slide rail 3 a. For example, the stopper 3b3 is a rubber pad, and when the slide lock piece 3b2 is locked, the front end of the slide lock piece 3b2 presses the rubber pad, thereby increasing the friction force between the rubber pad and the both. Preferably, the area of the stopper 3b3 may be larger than the end area of the front end of the lock bolt 3b21 or the spring pin 3b22, thereby further enhancing the locking effect of the slide lock 3b 2.
