[0025] The utility model provides Figure 1-Figure 4 The portable blind guide device shown in the figure includes: a handle head 1, one end of which is fixedly installed with a winding rope, and the handle head 1 is built with an ultrasonic ranging structure and a power supply and other structures, which are all existing mature technologies; a fixed part, the fixed part is fixedly installed at the other end of the handle head 1, and the fixed part is used to protect the handle head 1; a movable part, the movable part is connected to the fixed part, and the movable part is used to adjust the height of the stick body 2; the stick body 2, the stick body 2 is connected to the movable part, and the stick body 2 is specifically threadedly connected to the inner side of the connecting sleeve 8, which is convenient for disassembly and storage, thereby improving the portability of the device.

[0026] The fixed part includes a tube body 3 fixedly mounted on one end of the handle head 1, the tube body 3 is used to facilitate the movement of the connecting sleeve 8 therein, the plane 4 is used to cooperate with the guide block 13 to slide, and the groove 5 can facilitate the guiding and positioning of the slide rod 9. Planes 4 are arranged on opposite sides of the outer side of the tube body 3, a groove 5 is opened in the middle of one side of the plane 4, and concave holes 6 are opened at equal intervals on both sides symmetrically along the center line of the groove 5 on one side of the plane 4. The concave holes 6 are used to cooperate with the guide block 13 to control the damping feeling when adjusting the length of the stick body 2. A protective frame 7 is fixedly connected to the outer side of the tube body 3. The protective frame 7 has a larger profile and is used to avoid damage caused by the handle head 1 directly falling to the ground by colliding with the ground when the stick body 2 falls over, so as to improve the protection effect of the handle head 1 and the electronic components therein. The movable part includes A connecting sleeve 8 is slidably installed on the inner side of the tube body 3, and the connecting sleeve 8 can be conveniently threadedly connected to the stick body 2. A connecting hole is opened at one end of the connecting sleeve 8, and a thread is arranged inside the hole. Slide rods 9 are fixedly connected to the opposite sides of the outer side of the connecting sleeve 8, and the slide rods 9 are slidably installed between the inner sides of adjacent strip grooves 5. The outer sides of the two slide rods 9 are fixedly connected to the same outer ring 10, and the outer ring 10 is used to drive the connecting sleeve 8 to slide and adjust the specific height of the stick body 2. The locking ring 11 is used to fix the locking rod 12, and the locking rod 12 is used to lock the position of the outer ring 10 by squeezing when necessary, so as to facilitate the adjustment operation. The outer side of the outer ring 10 is fixedly connected to the locking ring 11, and the inner side of the locking ring 11 is threadedly connected to the locking rod 12, and the inner side of the outer ring 10 is respectively fixedly connected to guide blocks 13 on the opposite sides of the inner side.

[0027] A notch is provided on the protective frame 7, and clamping plates 14 are fixedly connected to both ends of the notch. The notch can facilitate the passage of a commonly used plastic bag or a dog leash, and the clamping plate 14 can facilitate the threading of the bag handle and the dog leash, so as to free the other hand of the blind person to the greatest extent, thereby improving the convenience of use.

[0028] An abutment portion 15 is provided on one side of the outer side of the protective frame 7. The abutment portion 15 is set as an inclined surface. A rubber pad is fixedly connected to the abutment portion 15. The inclined surface can facilitate the device to be placed against the wall.

[0031] When in use, the blind person first rotates the locking rod 12 according to his own height or with the help of others so that one end of it is no longer in contact with the tube body 3, pushes the outer ring 10 to make it slide in the groove 5 through the slide rod 9 to adjust the height of the stick body 2 to a suitable position, and at the same time makes the guide block 13 slide on the plane 4. When the guide block 13 enters the adjacent recessed hole 6, the friction force is significantly reduced, which is convenient for the user to feel. When the position is determined, the locking rod 12 is reselected to make one end of it contact the surface of the tube body 3 again to lock the current position of the stick body 2 and the connecting sleeve 8. In daily use, the user can place the device against the wall by tilting the stick body 2 so that one side of the abutting part 15 is against the wall to improve the stability of the device when placed. The user can also free one hand by passing the dog leash or plastic belt hole carried on a daily basis through the card plate 14 and sleeved on the outside of the card plate 14 to facilitate walking operation.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. 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.
