[0030] Please refer to Figure 1 - Figure 7 , this embodiment provides a multifunctional walking aid, including:

[0031] The main body 1 of the walking aid bracket, and a support handle 2 is provided on the upper part of the main body 1 of the walking aid bracket;

[0032] The support seat 3, and the support seat 3 is connected to the middle and upper region of the main body 1 of the walking aid bracket;

[0033] The leg lifter 4 is provided below the support seat 3 and is used to support the user's legs to be straightened or bent to a certain extent after the user sits on the support seat 3.

[0034] The walking aid bracket main body 1 serves as an overall bracket, supporting the handle 2 for the user to hold when walking or pausing to walk, preventing falls, and lifting the walking aid bracket main body 1 when moving the walking aid bracket main body 1 forward.

[0035] The support seat 3 is for the user to sit on when they don't want to move and exercise but want to rest, playing a supporting role. After the user sits on the upper surface of the support seat 3, the leg lifter 4 supports the user's legs to be straightened or bent to a certain extent.

[0036] If the distance from the upper surface of the support seat 3 to the ground is approximately equal to the length of the user's calf, then after the user sits on the support seat 3, with the sole of the foot on the ground, the thigh and calf are bent and folded at approximately ninety degrees. When the distance from the upper surface of the support seat 3 to the ground is closer, after the user sits down, with the sole of the foot on the ground, the included angle between the bent and folded thigh and calf is smaller, and vice versa.

[0037] In this embodiment, the distance from the upper surface of the support seat 3 to the ground is preferably such that after the user sits down, with the sole of the foot on the ground, the included angle between the bent and folded thigh and calf is greater than or equal to ninety degrees, so that the user doesn't have to squat too low and feel tense. And after the user sits on the support seat 3, the legs are supported to be bent to a certain extent. Here, the certain extent of bending means that within the range where the included angle between the thigh and calf is greater than ninety degrees and less than one hundred and eighty degrees, the state where the user's legs can stretch and bend without feeling uncomfortable.

[0038] In this way, the leg lifter 4 can prevent the user from having to exert effort to keep the legs suspended and straightened or bent to a certain degree, which is strenuous and uncomfortable. Moreover, this multifunctional walking aid can be used in three ways. Firstly, it can help the user walk. Secondly, it can be used for the user to sit and rest. Thirdly, it can assist the user in lifting the legs to be straightened or bent to a certain extent, having multiple functional roles.

[0039] Please refer to Figure 2 - Figure 4 、 Figure 6 and Figure 7, the leg lifter 4 includes a lockable gas spring 410, a control switch 420, a cable (not shown), a trigger switch 430, and a leg lifting bracket 440; one end of the leg lifting bracket 440 is rotatably connected to the lower end surface of the support base 3; one end of the lockable gas spring 410 is hinged to the lower end surface of the support base 3; the control switch 420 includes a grip handle 421 and a handle base 422, and the grip handle 421 is hinged to the handle base 422; the handle base 422 is connected to the main body 1 of the walking aid bracket; one end of the hose of the cable is fixedly connected to the handle base 422, and one end of the cable of the cable is connected to the grip handle 421; the trigger switch 430 includes a lever 431, a lever base 432, and a torsion spring 433, the lever base 432 is fixed to the end of the piston rod of the lockable gas spring 410, the other end of the hose of the cable is fixed to the lever base 432, and the lever base 432 is slidably and rotatably connected to the leg lifting bracket 440; the first end of the lever 431 is hinged to the lever base 432, and the second end of the lever 431 is connected to the other end of the cable of the cable; grasping the grip handle 421, the middle part of the lever 431 abuts against the locking rod protruding from the end of the piston rod of the lockable gas spring 410; the torsion spring 433 is used to keep the middle part of the lever 431 away from the locking rod protruding from the end of the piston rod of the lockable gas spring 410.

[0040] The user operates the grip handle 421 to pull the cable in the cable to drive the lever 431. The lever 431 rotates relative to the lever base 432, and the middle part of the lever 431 abuts against the locking rod protruding from the end of the piston rod of the lockable gas spring 410. If no force is applied to the piston rod to retract it into the lockable gas spring 410, the piston rod extends, driving the lever base 432 to move. Since the lever base 432 is slidably and rotatably connected to the leg lifting bracket 440 and the leg lifting bracket 440 does not receive a downward pressure, the lockable gas spring 410 drives the leg lifting bracket 440 to rotate and lift, thereby supporting the user's leg and straightening it or bending it to a certain extent. When the user releases the grip handle 421, under the action of the torsion spring 433, the lever 431 resets and immediately cancels abutting against the locking rod, and the piston rod maintains its extended length, so that a fixed height support can be continuously provided.

[0041] When it is necessary to rotate and lower the leg lifting bracket 440 and retract it under the support base 3, the grip handle 421 is also grasped. The middle part of the lever 431 abuts against the locking rod protruding from the end of the piston rod of the lockable gas spring 410, and at the same time, a force for rotating and pressing down the leg lifting bracket 440 is applied to overcome the force of the piston rod extending, and the piston rod retracts into the lockable gas spring 410.

[0042] During the process of the leg lifting bracket 440 rotating and rising or the leg lifting bracket 440 rotating and descending, the lockable gas spring 410 also rotates relative to the support base 3 with a certain degree of freedom.

[0043] By adopting the lockable gas spring 410, the leg lifter 4 can drive the leg lifting bracket 440 to move without using electric power.
