DETAILED DESCRIPTION

[0020] For the convenience of understanding the present application, the present application will be described more fully below with reference to the accompanying drawings. The drawings show several embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present application is more thorough and complete.

[0021] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] A walking stick for Parkinson's patients, comprising Figure 1 and Figure 3As shown, the cane includes a support pole 1, multiple legs 2 arranged circumferentially at the lower part of the support pole 1, a handle 3 arranged at the upper part of the support pole 1, the patient's hand gripping the handle 3 to use the cane, two side limiting mechanisms 4 arranged at the upper part of the support pole 1, and an upper limiting mechanism 5 arranged on the two side limiting mechanisms 4; wherein, the two side limiting mechanisms 4 include a slide rail 41 arranged on the support pole 1, two sliding plates 42 respectively slidably connected on both sides of the slide rail 41, and a first drive assembly 44 for driving the two sliding plates 42 to move synchronously, the two sliding plates 42 moving towards each other to limit the lateral position of the patient's hand; the upper limiting mechanism 5 can slide vertically to limit the upper position of the patient's hand.

[0024] Among them, such as Figure 2 As shown, the upright 1 includes a sleeve 11 and a first sliding rod 12. The sleeve 11 has an inner cavity 13 and an exhaust hole 14 communicating with the inner cavity 13. A portion of the first sliding rod 12 is sleeved in the inner cavity 13 and slidably connected to the inner cavity 13. A spring 6 is connected between the first sliding rod 12 and the sleeve 11. The spring 6 is located in the inner cavity 13. Three support legs 2 are provided along the circumference of the lower part of the sleeve 11. The three support legs 2 are evenly spaced. A handle 3 is provided on the upper part of the first sliding rod 12. The three support legs 2 at the lower part of the sleeve 11 help to maintain the balance of the cane and increase the contact area between the cane and the ground. The spring 6 is connected between the first sliding rod 12 and the sleeve 11. When the upper part of the cane shakes, the spring 6 will contract. During the contraction process, it can play a shock absorption role and effectively prevent the cane from shaking due to the patient's hand tremors, so that the cane always maintains balance. The exhaust hole 14 is used for the first sliding rod 12 to slide well in the inner cavity 13.

[0025] Understandably, when using this cane, the patient first grasps the handle 3, then the operator operates the first drive assembly 44. The first drive assembly 44 drives the two sliding plates 42 to move towards each other, bringing them closer to the patient's hand. The operator can either allow the two sliding plates 42 to directly contact the patient's hand, or leave a small gap between them to increase patient comfort. When the patient's hand trembles, the two sliding plates 42 restrict the hand's position between them, preventing the hand from slipping off one side of the plates, thus ensuring a stable grip on the cane. After adjusting the distance between the two sliding plates 42 and the patient's hand, the operator can operate the upper limiting mechanism 5. The upper limiting mechanism 5 moves downward, thereby limiting the upper part of the patient's hand and preventing slippage due to hand tremors, further ensuring a stable grip on the cane.

[0026] like Figure 4As shown, the first drive assembly 44 includes a rotating shaft 441 rotatably connected on the slide rail 41, two external threads 442 symmetrically arranged on both sides of the rotating shaft 441 respectively, and a knob 443 arranged on one end of the rotating shaft 441; the rotating shaft 441 is threadedly connected with the two slide plates 42 through the two external threads 442 respectively.

[0027] It can be understood that the operator can rotate the knob 443 in the forward direction, the knob 443 rotates to drive the rotating shaft 441 to rotate, the rotating shaft 441 rotates to drive the external threads 442 thereon to rotate, the two slide plates 42 are provided with internal threads, and the internal threads of the slide plates 42 cooperate with the external threads 442, so that the two slide plates 42 move towards each other, and conversely when the knob 443 is rotated in the reverse direction, the two slide plates 42 move away from each other.

[0028] The two side limiting mechanisms 4 further include a plurality of first flexible members arranged on one side of the two slide plates 42.

[0029] It can be understood that the first flexible member is a first air bag 43, a silica gel pad, a rubber pad, etc., and one or more first flexible members can be arranged on the slide plate 42. When the two slide plates 42 move close to each other, the patient's hand is located between the two slide plates 42, and when the patient's hand shakes, the first flexible member can protect the patient's hand and prevent the patient's hand from being rigidly collided with the slide plate 42 to cause discomfort.

[0030] As shown in Figure 5 The upper side limiting mechanism 5 includes two sliding blocks 51 slidably connected on the two slide plates 42 respectively, a second slide rod 52 penetrating through the two sliding blocks 51 and slidably connected with the sliding blocks 51, and a second drive assembly 55 for driving the sliding blocks 51 to move.

[0031] Among them, the two upper slide plates 42 are provided with slide holes 54, and the sliding blocks 51 are slidably connected with the slide plates 42 through the slide holes 54. It can be understood that when it is necessary to limit the upper side of the patient's hand, the operator can operate the second drive assembly 55, the second drive assembly 55 drives the sliding blocks 51 to move downward, the sliding blocks 51 move downward to drive the second slide rod 52 to move downward, so that the second slide rod 52 is close to the patient's hand. Of course, the second slide rod 52 can be in direct contact with the patient's hand, or there can be a small gap between the second slide rod 52 and the patient's hand. By moving the second slide rod 52 close to the patient's hand, the patient's hand is prevented from sliding from the upper side of the crutch, and further, the second slide rod 52 is slidably connected with the sliding blocks 51 to enable the slide plates 42 to slide well on the slide rail 41.

[0032] The middle part of the second slide rod 52 is provided with a second flexible member, and the second flexible member is arranged on the outer wall of the second slide rod 52.

[0033] It can be understood that the second flexible member is a second air bag 53, a silica gel pad, a rubber pad or the like, and one or more second flexible members can be arranged on the second sliding rod 52, and the second flexible member has the same effect as the first flexible member, and thus no more description is made.

[0034] In the embodiment, the second driving assembly 55 includes a screw rod 551 threadedly connected to one of the sliding plates 42, and the end of the screw rod 551 is rotationally connected to the adjacent sliding block 51, and rotating the screw rod 551 drives the sliding block 51 to move vertically.

[0035] It can be understood that the operator rotates the screw rod 551 in the forward direction to drive the sliding block 51 to move downward, so that the second sliding rod 52 is close to the patient's hand, and the operator rotates the screw rod 551 in the reverse direction to make the second sliding rod 52 away from the patient's hand; as shown in FIG. 5, in other embodiments, the rotation of the screw rod 551 can be replaced by electricity to make the crutch more convenient to use. Specifically, the second driving assembly 55 further includes a third sliding rod 552 arranged on the sliding plate 42 connected with the screw rod 551, a sliding frame 553 slidably connected to the third sliding rod 552, a motor 554 arranged on the sliding frame 553, and a switch 555 arranged on the handle 3, the output shaft of the motor 554 is fixedly connected with the screw rod 551, the motor 554 is started by pressing the switch 555, and the motor 554 drives the screw rod 551 to rotate; Figure 6

[0036] The switch 555 can be a press or touch switch 555, and in the embodiment, it is a press switch 555. The operator can press the switch 555, and at this time, the controller controls the motor 554 to start, and drives the screw rod 551 to rotate in the forward direction, so that the second sliding rod 52 is close to the hand. When the operator releases the switch 555, the controller controls the motor 554 to stop working, and the screw rod 551 is in a stationary state. When the operator quickly presses and then releases the switch 555, the controller controls the motor 554 to drive the screw rod 551 to rotate in the reverse direction, so that the second sliding rod 52 moves upward to the limit position, and then the motor 554 automatically stops working. The electrical control principle is prior art, and thus no more description is made.

[0037] ​In summary, by driving the two sliding plates 42 to move towards each other by the first driving assembly 44, the two sliding plates 42 are moved close to the patient's hand, when the patient's hand shakes, the patient's hand is limited between the two sliding plates 42 by the two sliding plates 42, avoiding the patient's hand from sliding from one side of the sliding plate 42, so that the patient can hold the crutch stably, avoiding sliding, when the distance between the two sliding plates 42 and the patient's hand is adjusted, the operator can operate the upper limiting mechanism 5, the upper limiting mechanism 5 moves downward, thereby limiting the upper part of the patient's hand by the upper limiting mechanism 5, preventing the patient's hand from shaking and causing sliding from the upper part of the crutch, further making the patient hold the crutch stably.
