Elastic component 341a, 341b with arcuation contact surface of directional spreding, can different location according to human body or different people
Leg fineness, vertical direction can be located remotely from each other or closely slide to adjust it is the distance between opposite, it is such as opposite
In the people that leg is thick, when contact portion 34 comes into contact with the skin of its leg, top elastic component 341a and lower elastic part 341b
It gradually opens along the vertical direction, and makes the adaptive different leg type of fitting cambered surface 341c, can greatly improve relaxing for patient
Suitable sense.In this embodiment, it can be hauled by tension spring (not shown) between top elastic component 341a and lower elastic part 341b,
Also, the first elastic component 341 as a whole can also be hauled by tension spring, in order to the adaptive tune of the first elastic component 341
It is whole.
In addition, an alternate embodiment as the embodiment, the second mounting blocks 342 are in U shape, top elasticity
Part 341a and lower elastic part 341b are partially accommodated in respectively in the second mounting blocks 342, also, top elastic component 341a and second
Between the top of mounting blocks 342 and/or between lower elastic part 341b and the lower part of the second mounting blocks 342, it is provided with compression bullet
Spring 344.In this embodiment, preferably between top elastic component 341a and the top of the first mounting blocks 333 and lower elastic
Between part 341b and the lower part of the second mounting blocks 342, it is provided with compressed spring 344, to realize the lower part bullet under original state
Property part 341b and lower elastic part 341b mutually abut, lesser fitting cambered surface 341c is formed, when the contact human body of contact portion 34
After skin, with the further feeding of feed mechanism 32, top elastic component 341a and lower elastic part 341b squeeze compression respectively
Fitting cambered surface 341c is become larger, therefore is adapted to the different location of different leg types, leg by spring 344.
In the above description, although not doing detailed differentiation to technical characteristics such as such as threaded hole, compressed spring, screw rods,
But when these technical characteristics have different appended drawing references, it is meant that it is distributed in different components, belongs to different
Technical characteristic.
Each specific technical characteristic as described in the above specific embodiments in the case of no contradiction can be with
It is combined in any manner, for unnecessary repetition, the present invention is to various combinations of possible ways not otherwise stated.
The above examples are only used to illustrate the technical scheme of the present invention and is not intended to limit it, all without departing from the present invention
Any modification of range or equivalent replacement should all be included in technical solution of the present invention.
