[0043] Furthermore, the second support member includes a second support rod 3; the handlebar rod 34 is rotatably connected to the first support rod 2 and the second support rod 3, respectively, and the handlebar rod 34 is locked on the second support rod 3 by a locking member 33; after the locking assembly is unlocked, the handlebar rod 34 can be rotated relative to the second support rod 3 to unlock the first locking mechanism and the second locking mechanism; the device can lock the handlebar rod 34 with the second support rod 3 through the provided locking assembly, that is, when in use, it can ensure that the handlebar rod 34 is fixed to the first support rod 2, that is, it can facilitate the fixation of the device, the locking member 33 includes a rotating block 331 rotatably arranged on the second support rod 3, and a locking rod 332 is rotatably arranged on the rotating block 331, and a torque spring is arranged on the hinge shaft between the rotating rod and the rotating block 331, and its elastic force can make the locking rod 332 inserted into the locking groove 3401 opened on the handlebar rod 34.

[0044] Furthermore, the first locking mechanism includes a connecting sleeve 21 fixedly arranged at one end of the first support rod 2 and a locking sleeve 211 sliding along the axial direction of the connecting sleeve 21, and the connecting sleeve 21 and the locking sleeve 211 can rotate synchronously; it also includes a fixed shaft 4 fixedly arranged on the support frame 1, and a locking block 41 adapted to the locking sleeve 211 is fixedly arranged on the fixed shaft 4, so that when the locking block 41 and the locking sleeve 211 are in contact, the rotation of the first support rod 2 is restricted.

[0045] Furthermore, it also includes a rotating shaft 2111 rotatably arranged on the connecting sleeve 21, and a pull rope 2112 wound around the rotating shaft 2111, one end of the pull rope 2112 is fixedly connected to the locking sleeve 211, and the other end is connected to the handlebar rod 34; when the handlebar rod 34 rotates, the pull rope 2112 is pulled to drive the locking sleeve 211 to disengage from the locking block 41.

[0046] Furthermore, an elastic member is arranged between the locking sleeve 211 and the connecting sleeve 21, and its elastic force causes the locking sleeve 211 to contact the locking block 41. The second support member also includes a telescopic rod 31 slidably arranged on the second support rod 3 and a supporting connecting rod fixedly arranged on the telescopic rod 31. The supporting connecting rod 32 is rotatably arranged on the round rod under the support frame 1, and the second locking mechanism is arranged in the second support rod 3 to limit the relative sliding of the second support rod 3 and the telescopic rod 31.

[0047] Furthermore, the second locking mechanism includes a slider 311 fixedly arranged on the telescopic rod 31 and a friction block 3111 sliding in the radial direction of the slider 311. A pressing component for pressing against the friction block 3111 is also arranged inside the second support rod 3. The pressing component is inserted into the slider 311 to form a locking groove 3112 to press against the friction block 3111, so that the friction block 3111 presses against the inner wall of the second support rod 3 to lock it. The device has a function of improving the stability between the second support rod 3 and the telescopic rod 31, that is, when the handrail rod 34 is pressed downward, After the force is applied, the transmission gear 36 will drive the transmission rack 361 to move, that is, the transmission rack 361 moves downward, so that the vertical insertion rod 362 has a downward movement drive, that is, it can drive the inclined block 51 to more closely contact the friction block 3111, so that the friction block 3111 contacts the inside of the second support rod 3, thereby further improving the friction force between the friction block 3111 and the inner wall of the second support rod 3, and can utilize the downward pressure of the handrail rod 34 to convert it into the friction force of the friction block 3111 on the inner wall of the second support rod 3, thereby improving the overall stability between the second support rod 3 and the telescopic rod 31.

[0048] Furthermore, the clamping assembly includes a first sliding block 5 sleeved inside the second support rod 3, the first sliding block 5 is provided with an oblique block 51 sliding in the radial direction, a first elastic member 511 is provided between the oblique block 51 and the first sliding block 5, and also includes a vertical plug rod 362 provided inside the second support rod 3, and the first sliding block 5 and the sliding block 311 are respectively sleeved on the periphery of the vertical plug rod 362; and a first locking tooth 3621 is provided on the vertical plug rod 362, and a second locking tooth 512 adapted to the first locking tooth 3621 is also provided on the oblique block 51; when the oblique block 51 is inserted into the locking groove 3112, the first locking tooth 3621 and the second locking tooth 512 are engaged, so that the oblique block 51 and the vertical plug rod 362 are relatively fixed.

[0049] Furthermore, a transmission rack 361 is fixedly provided on the top of the vertical insertion rod 362, and a transmission gear 36 meshing with the transmission rack 361 is also provided on the handrail rod 34; when the handrail rod 34 rotates downward, the transmission rack 361 and the transmission gear 36 act to make the vertical insertion rod 362 have a downward pressing force. Specifically, a barrier assembly is also provided on the periphery of the vertical insertion rod 362, and the barrier assembly includes a second sliding block 6 and a one-way latch tooth 61 slidably provided in the second sliding block 6, and a second elastic member 611 is provided between the one-way latch tooth 61 and the second sliding block 6 , under the elastic force of the second elastic member 611, the one-way latch 61 can be engaged with the first locking latch 3621 set on the vertical plug rod 362, and during the engagement process, the one-way latch 61 has an engaging force along the vertical plug rod 362 toward the supporting connecting rod 32. Therefore, the second sliding block 6 can move upward along the vertical plug rod 362, but cannot move downward along the vertical plug rod 362, so that when the vertical plug rod 362 moves downward, it can synchronously drive the vertical plug rod 362 to move downward, so as to facilitate pressing the first sliding block 5 downward and moving it into the locking groove 3112.

[0050] When the present invention needs to adjust the first support rod 2 and the second support member, Fig.12 As shown, first, the locking rod 332 is rotated away along the rotation axis of the rotating block 331, so that the locking rod 332 is separated from the locking groove 3401, and then the handlebar rod 34 can be rotated along the second support rod 3, and then as shown in FIG. Figure 1 As shown, the handlebar rod 34 is rotated upward, and then the handlebar rod 34 is rotated along the axis rotating with the second support rod 3 and the first support rod 2, while rotating:

[0051] 1. The rotating shaft wound on the handrail rod 34 starts to rotate, thereby pulling the pull rope 2112 set on the rotating shaft to start rotating. The locking sleeve 211 connected to the other end of the pull rope 2112 is separated from the locking block 41 under the pulling force of the pull rope 2112, and then the first support rod 2 and the connected connecting sleeve 21 are no longer locked by the locking block 41, that is, the first support rod 2 can slide relative to the fixed shaft 4;

[0052] 2. The transmission gear 36 rotates synchronously to drive the transmission rack 361 to move upward, that is, to drive the connected vertical plug rod 362 to move upward. At this time, since the first locking tooth 3621 set on the vertical plug rod 362 is engaged with the second locking tooth 512, when the vertical plug rod 362 moves upward, it can synchronously drive the second locking tooth 512 and the oblique block 51 to disengage from the locking groove 3112. Then, when disengaging, the oblique block 51 pops open under the elastic force of the first elastic member 511, so that the first locking tooth 3621 and the second locking tooth 512 are separated, and at this time, the friction block 3111 is no longer affected by the resistance of the oblique block 51, thereby losing the friction force against the inside of the second support rod 3; so that the oblique block 51 and the telescopic rod 31 can slide relative to the second support rod 3.

[0053] In summary, the first locking mechanism and the second locking mechanism on the first support rod 2 and the second support rod 3 are unlocked respectively, so that the first support rod 2 and the second support rod 3 can rotate along the support frame 1, and then the user can adjust the appropriate angle downward according to his actual situation or the actual geological situation. During the adjustment process, the second support rod 3 and the telescopic rod 31 can slide relative to each other, and the first support rod 2 rotates along the fixed axis 4. After the adjustment is completed, the handrail rod 34 is rotated in the opposite direction along the axis rotating with the first support rod 2 and the second support rod 3, and then the connected transmission rack 361 can be driven to move, and the transmission rack 361 can be driven to move downward, so that the vertical insertion rod 362 synchronously drives the engaged one-way locking tooth 61 to move downward, and the second sliding block 6 is fixedly set on the first sliding block 5, that is, when the vertical insertion rod 362 moves downward, it drives the first sliding block 5 to be inserted into the locking groove 3112, and then the inclined block 51 is abutted against the friction block 3111, so that it can abut against the friction block 311 1, so that the friction block 3111 abuts against the inner wall of the second support rod 3, and a friction plate adapted to the friction block 3111 is also provided on the inner wall of the second support rod 3 to increase the friction between the module, so that the friction block 3111 can be fixed to the inner wall of the second support rod 3, that is, it is used to support the handlebar rod 34, and the device has a function to improve the stability between the second support rod 3 and the telescopic rod 31, that is, after the handlebar rod 34 is subjected to downward pressure, the transmission gear 36 will drive the transmission rack 361 to move The movement of the transmission rack 361 causes the transmission rack 361 to move downward, so that the vertical insertion rod 362 has a downward movement drive, that is, it can drive the inclined block 51 to more closely contact the friction block 3111, so that the friction block 3111 contacts the inside of the second support rod 3, thereby further improving the friction between the friction block 3111 and the inner wall of the second support rod 3, and can utilize the downward pressure of the handrail rod 34 to convert the friction force of the friction block 3111 on the inner wall of the second support rod 3, thereby improving the overall stability between the second support rod 3 and the telescopic rod 31.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
