In the present embodiment, the structure of 1 Upper shaft sleeve 11 of arm blaster is worth as shown in figure 4, be the cylinder of semi-circular shape for section
Illustrating, it can also be other structures that the concrete shape structure of this axle sleeve 11 is in the present embodiment in other embodiments,
As long as axle sleeve 11 can be matched with pivot 21.
As shown in Figures 2 and 3, the top surface of slide 2 is equipped with the mounting groove 22 for being in the periphery of pivot 21, mounting groove 22 around
Pivot 21, the purpose of setting mounting groove 22 are for placing the first bolster 6 and the second bolster 7.
Wherein the first block piece 23 is arranged in the inner wall of mounting groove 22, when arm blaster 1 and slide 2 are rotatablely installed, axle sleeve 11
A part protrudes into and is used as the second block piece in mounting groove 22, and the first bolster 6 is located in mounting groove 23 and in circumferential direction respectively with the
One block piece 23 and the second block piece offset;The groove bottom part of mounting groove 22 is arranged in second bolster 7, in the second bolster 7
Top is provided with float plate 24, and the second bolster 7 is placed between float plate 24 and the slot bottom of mounting groove 22, the first bolster 6 peace
It sets in the float plate 24, the end face of the axle sleeve 11 as the second block piece circumferentially offsets with the first bolster 6 along mounting groove.
Specifically, in the present embodiment, the first block piece 23 is demarcation plate, and demarcation plate is connected with float plate 24,
Demarcation plate is arranged in mounting groove 22 by the locating slot 25 on 22 inner wall of mounting groove, and float plate 24 is arranged on the pivot shaft 21,
Middle demarcation plate can be axially moved in locating slot 25 along pivot 21, wherein the Arc Spring as the first bolster 6 is
Two, be both placed in float plate 24, and two Arc Springs with as the first block piece 23 demarcation plate and conduct
The axle sleeve 11 of second block piece offsets, and the linear helical spring as the second bolster 7 is placed in 22 slot bottom of mounting groove and floats
Between plate 24.
Further, when arm blaster 1 is connect with slide 2, and the axle sleeve 11 on arm blaster 1 is as the second block piece,
Two Arc Springs of the axle sleeve 11 respectively with float plate 24 and as the first bolster 6 offset, when arm blaster 1 and slide 2
When relative rotation, two Arc Springs can play circumferential buffer function, when between arm blaster 1 and slide 2 along 21 axis of pivot
Axial buffer can be played to linear helical spring when relative motion, being placed between 22 slot bottom of float plate 24 and mounting groove to make
With, thus guarantee that patient's training is gone on smoothly, the comfort of increase Rehabilitation training.
It is worth noting that in other embodiments, the first block piece 23 can also be other barrier structures, demarcation plate is
Selection in the present embodiment, in other embodiments, the first block piece 23 is also structure as a whole with the inner wall in mounting groove 22 or it
His connection type, the first block piece 23 can also need not be connected with float plate 24, need to only meet the first block piece 23 and stop first
Bolster 6, float plate 24 separate the first bolster 6 and the second bolster 7.
As shown in figure 4, the inner wall of axle sleeve 11 is equipped with limited step 111, pivot 21 is equipped with gag lever post 211, the gag lever post
211 one end is extended in axle sleeve 11 above limited step 111, and the end of gag lever post 211 is equipped with and 111 phase of limited step
The anti-drop head 212 supported.
In the present embodiment, gag lever post 211 is caging bolt, and anti-drop head 212 is anti-flake, when arm blaster 1 passes through pivot
21 with slide 2 when being connected, and the caging bolt on pivot 21 interacts with the anti-flake being located on limited step 111,
Caging bolt is connected with pivot 21 again, to guarantee the rotational installation between arm blaster 1 and slide 2.
