[0038] As Figures 1 to 2 、 Figure 7 shown, in one embodiment, a paralytic crutch 1 with an adjustable arm rod includes a rod body 10 and a gripping member 20. The gripping member 20 includes an arm rod 21, a socket 22, a grip 23 and a clamping post 24. The socket 22 is arranged on the rod body 10, and a plurality of adjustment holes 221 are formed in the socket 22. The clamping post 24 is arranged on the arm rod 21, and the arm rod 21 is inserted into the socket 22 so that the clamping post 24 is clamped with any one of the adjustment holes 221, making the relative height of the arm rod 21 and the socket 22 adjustable. The grip 23 is arranged on the socket 22.

[0039] It should be noted that the arm rod 21, socket 22, grip 23 and clamping post 24 included in the holding member 20 are all made of hard plastic. One end of the socket 22 is sleeved with the rod body 10, and the other end of the socket 22 is sleeved with the arm rod 21, so that the arm rod 21 and the rod body 10 are in a straight line. Each adjustment hole 221 is arranged at equal intervals on one end of the socket 22 close to the arm rod 21. When the arm rod 21 is inserted into the socket 22, the arm rod 21 will drive the clamping post 24 to insert into the socket 22. Since the clamping post 24 is located on the contact area of the insertion and connection between the arm rod 21 and the socket 22, the clamping post 24 is stuck at the opening of the socket 22, so that the arm rod 21 cannot be completely inserted into the socket 22. It should be noted that a U-shaped clearance groove is provided on the arm rod 21, and the clamping post 24 is located on the annular end of the U-shaped. Due to the elastic return characteristic of the hard plastic material, the U-shaped structure on the arm rod 21 also has the elastic return characteristic, so that the U-shaped structure can drive the clamping post 24 to perform elastic return. When the clamping post 24 is located at the opening of the socket 22, by pressing the clamping post 24, the clamping post 24 is contracted towards the inside of the arm rod 21. In this way, the arm rod 21 can be completely inserted into the socket 22. When the arm rod 21 drives the clamping post 24 to slide to the adjustment hole 221 on the socket 22, the clamping post 24 will pop out from the adjustment hole 221 due to its own elastic return characteristic. In this way, the arm rod 21 cannot be pulled out of the socket 22, so that the arm rod 21 is fixed at the required height.

[0040] As Figures 1 to 2 、 Figure 7 shown, in one embodiment, the grip 23 and the socket 22 are of an integrally formed structure.

[0041] It should be noted that the grip 23 is arranged at the middle position of the socket 22, so that the socket 22 tends to be a tee structure to increase the firmness of the socket 22. Further, a soft rubber sleeve 231 is provided on the grip 23, and the soft rubber sleeve 231 and the grip 23 are also of an integrally formed structure to prevent the soft rubber sleeve 231 from falling off the grip 23 after becoming loose during long-term use. A number of anti-slip lines 2311 are provided on the soft rubber sleeve 231 to increase the holding stability and the holding hand feeling experience of the patient.

[0042] As Figures 1 to 2 、 Figure 7 shown, in one embodiment, the holding member 20 further includes an arm ring 25, and the arm ring 25 is rotatably arranged on the arm rod 21.

[0043] It should be noted that the arm ring 25 is rotatably arranged at one end of the arm rod 21 away from the socket 22. When the patient holds the grip 23 with the hand, the arm ring 25 can be sleeved on the patient's arm so that the holding member 20 is fixed on the patient's arm. Further, when the patient's arm is too long, by pressing the clamping post 24, the arm rod 21 can slide out of the socket 22 outward. When the arm rod 21 drives the clamping post 24 to slide to the adjustment hole 221 on the socket 22, the clamping post 24 is clamped into the adjustment hole 221 again. In this way, the arm rod 21 drives the arm ring 25 to rise to a height suitable for the patient's arm. Further, the arm ring 25 is provided with a notch at one end away from the arm rod 21. In this way, the patient can, according to his own usage situation, first put the hand through the arm rod 21 and then hold the grip 23, or first hold the grip 23 and then the arm is clamped into the arm ring 25 from the notch.

[0044] As Figures 1 to 2 、 Figures 6 to 7 shown, in one embodiment, the rod body 10 includes a sleeve 11 and a support tube 12. The sleeve 11 is sleeved on the support tube 12, and the socket 22 is arranged on the sleeve 11.

[0045] It should be noted that both the sleeve 11 and the support tube 12 are hollow structures. One end of the sleeve 11 is sleeved with the end of the socket 22 away from the arm rod 21, and the other end of the sleeve 11 is sleeved with the support tube 12, so that the support tube 12 can slide in the sleeve 11. A plurality of through holes 111 are formed in the sleeve 11, and the through holes 111 are arranged on the sleeve 11 at equal intervals.

[0046] As Figures 1 to 2 、 Figures 6 to 7 shown, in one embodiment, the rod body 10 further includes a spring post 13. The spring post 13 is arranged in the support tube 12 and is used for clamping any one of the through holes 111.

[0047] It should be noted that the rod body 10 further includes a spring piece 14. The spring piece 14 is in a U-shaped structure. The spring piece 14 is located in the support tube 12 so that both ends of the spring piece 14 simultaneously push against the inner side wall of the support tube 12. The spring post 13 is arranged on one end of the spring piece 14. A round hole is formed in the support tube 12. The spring piece 14 pushes the spring post 13 to sequentially pass through the round hole and the through hole 111 so that the support tube 12 clamps the sleeve 11. Further, the rod body 10 further includes a shock-absorbing foot pad 15. The shock-absorbing foot pad 15 is arranged on the end of the support tube 12 away from the sleeve 11.

[0048] As Figures 2 to 3 、 Figures 7 to 10As shown, in one embodiment, the paralysis crutch 1 with an adjustable arm further includes an auxiliary component 30, which includes a swivel seat 31, a sleeve 32, a secondary rod 33, a locking ring 34 and a connecting block 35. The swivel seat 31 is arranged on the sleeve 22, the sleeve 32 is rotatably arranged on the swivel seat 31, the secondary rod 33 is inserted into the sleeve 32, the locking ring 34 is sleeved on the sleeve 11, and the connecting block 35 is rotatably connected to the locking ring 34 and the sleeve 32 respectively.

[0049] It should be noted that the swivel base 31 has a T-shaped structure and is disposed on the side of the sleeve 22 away from the handle 23. For example, the swivel base 31 and the sleeve 22 are integrally formed. One vertical end of the swivel base 31 is rotatably connected to one end of the sleeve head 32. The other end of the sleeve head 32 is sleeved onto the secondary rod 33, so that the sleeve head 32 drives the secondary rod 33 to rotate. Furthermore, a locking ring 34 is sleeved on the sleeve 11, and the locking ring 34 is located close to one end of the sleeve 22. The ends of the connecting block 35 are rotatably connected to the locking ring 34 and the sleeve head 32, respectively. For example, the connecting block 35 is rotatably connected to the locking ring 34 and the sleeve head 32 via a latch. The sleeve 11 also has a locking hole, which is located immediately below the locking ring 34. Furthermore, the rod body 10 also includes a top plate 112 and a boss 113. The top plate 112 is located in the sleeve 11. The top plate 112 pushes the boss 113 out of the lock hole. When the lock ring 34 slides through the lock hole and approaches the sleeve 22, the top plate 112 pushes the boss 113 to clamp the lock ring 34, so that the lock ring 34 is fixed to the end of the sleeve 11 near the sleeve 22. Because both ends of the connecting block 35 are rotatably connected to the lock ring 34 and the sleeve head 32, the lock ring 34 keeps pushing the sleeve head 32 away from the sleeve 22. In this way, the paralysis crook 1 of the adjustable arm will open the secondary rod 33, so that the secondary rod 33 maintains to form a triangular support frame with the rod body 10. Furthermore, a top angle is provided at one end of the sleeve head 32 near the swivel seat 31. When the paralysis crook 1 of the adjustable arm opens the secondary rod 33, the top angle abuts the swivel seat 31 to ensure that the secondary rod 33 is opened to a fixed angle.

[0050] For ease of description, the pivot point of the locking ring 34 and the connecting block 35 is defined as the A-axis point, the pivot point of the socket head 32 and the connecting block 35 is defined as the B-axis point, and the pivot point of the socket head 32 and the turntable 31 is defined as the C-axis point. Since the turntable 31 and the socket head 32 are connected at the C-axis point, when the turntable 31 is fixed to the socket 22, the socket head 32 can rotate around the C-axis point, and further, the socket head 32 drives the B-axis point to rotate around the C-axis point. Further, when the B-axis point rotates around the C-axis point, the B-axis point slides close to or away from the socket 22 along an arc. When the B-axis point slides from one end of the arc away from the socket 22 to the middle position of the arc, at this time, the A-axis point, the B-axis point and the C-axis point are all on a straight line, and the locking ring 34 slides down to the maximum lower limit, and further, the auxiliary rod 33 approaches the rod body 10, and the locking ring 34 stays above the lock hole, so that the convex column 113 cannot be ejected, and further, the locking ring 34 can continue to slide. When the B-axis point continues to slide from the middle position of the arc towards the socket 22, the socket head 32 pulls the locking ring 34 to slide up close to the socket 22, and the locking ring 34 slides over the lock hole, so that the convex column 113 extends out of the lock hole to top the locking ring 34, and further, the locking ring 34 cannot slide, and the locking ring 34 is fixed at one end of the sleeve 11 close to the socket 22. Since both ends of the connecting block 35 are rotationally connected to the locking ring 34 and the socket head 32, the locking ring 34 keeps pulling the socket head 32 close to the socket 22. Thus, the paralysis crutch 1 of the adjustable arm rod will retract the auxiliary rod 33 and keep the auxiliary rod 33 parallel to the rod body 10. Thus, for a patient with a single paralyzed leg, a triangular support point can be formed, enabling the patient to be more stable during movement and avoiding the risk of the patient falling forward or backward.

[0051] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
