According to the present invention, preferably, the first and second supporting members 23 and 33 may be preferably supporting nylon cloth, opposite sides of the supporting nylon cloth are curled to form the guide channels 5, and the two first adjusting rods 21 and the two second adjusting rods 32 can respectively penetrate into the guide channels 5 corresponding thereto to fix the supporting nylon cloth between the two first adjusting rods 21 or the two second adjusting rods 32, wherein a width between the two first adjusting rods 21 and a width between the two second adjusting rods 32 may be smaller than a width between the two guide channels 5. The arrangement of the guide channel 5 facilitates rapid fixing of the first support element 23 between the two first adjustment levers 21 and the second support element 33 between the two second adjustment levers 32; and the width between the two first adjusting rods 21 and the width between the two second adjusting rods 32 are set to be smaller than the width between the two guide channels 5, so that the first supporting piece 23 and the second supporting piece 32 are bent towards the supporting base 1 when not supporting legs, so as to better support and match the appearance of the legs of the human body, thereby not only providing good support for the patient, but also enabling the patient to feel more comfortable. First bearing piece 23 and second bearing piece 33 except can use the bearing nylon cloth can also select the bearing cotton, and wherein the bearing nylon cloth has better bearing capacity and the bearing cotton has better ventilative and travelling comfort.
In addition, as shown in fig. 1, a pedal 311 may be further disposed on the support rod 31, and the pedal 311 may be configured to be rotatably connected to the support rod 31 and to be capable of being positioned with respect to the support rod 31. With this arrangement, the pedal 311 supports the foot of the patient, while the angle between the pedal 311 and the support bar 31 can be adjusted to obtain an angle that makes the patient more comfortable.
In the embodiment shown in fig. 4 and 5, the outer wall of the linear bearing 4 may be formed with a positioning through hole 41, the first support member 2 and the second support member 3 may further include a positioning member 6 engaged with the positioning through hole 41, and the positioning member 6 may be configured to pass through the positioning through hole 41 and press-fixed against the outer circumferential wall of the pipe segment slidably connected in the linear bearing 4. The linear bearing 4 and the positioning member 6 are used in combination to adjust the lengths of the first adjustment lever 21 and the second adjustment lever 32 and to perform positioning at the same time.
Specifically, taking the example that the second tube section 212 is fixedly connected to one end of the linear bearing 4, and the first tube section 211 is slidably connected to the inner wall of the linear bearing 4, when an external force acts on the first tube section 211 slidably connected to the inner wall of the linear bearing 4, and the first tube section 211 is drawn out or retracted from the linear bearing 4 to a certain position, the length of the first support member 2 and the third support member 3 matching the individual condition of the patient can be obtained, then the positioning member 6 is inserted through the positioning through hole 41, so that the pressing end of the positioning member 6 is abutted to the outer peripheral wall of the first tube section 211 in the linear bearing 4, the axial movement of the first tube section 211 is limited by the pressing force, so that the first tube section 211 in the linear bearing 4 cannot slide any more, and the length of the first adjusting rod 21 and/or the second adjusting rod 32 is determined.
Preferably, the positioning through hole 41 may be a threaded hole, and the positioning member 6 is a bolt threadedly engaged with the threaded hole.
Returning to the embodiment shown in fig. 1 to 3, in a state where the bottom end C of the second support member 3 is positioned in the adjustment groove 111, one end of the second pipe section 212 hinged to the support base 11 and one end of the fourth pipe section 322 near the adjustment groove 111 may be respectively configured with arc-shaped sections 213 bent away from each other. This arc section 213's setting makes the bottom C of second supporting component 3 can form the basis of stable location with the constant head tank, still can be when first regulation pole 21, second regulation pole 32 bear pressure, provide certain cushioning effect to first regulation pole 21, second regulation pole 32, can avoid first regulation pole 21, second regulation pole 32 to take place to damage under thigh or shank exert instantaneous pressure to first regulation pole 21, second regulation pole 32 promptly, help prolonging its life.
