[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a wire harness protective case on a steering column includes a movable shell 1. A sliding groove 2 is provided inside the movable shell 1. A first extension plate 3 is slidably connected inside the movable shell 1. When the movable shell 1 is closed, the two sides of the movable shell 1 will be clamped together. The user can open the movable shell 1. The inner side wall of the sliding groove 2 is relatively smooth, and the friction force received by other objects when moving on the inner side wall of the sliding groove 2 is small. The movable shell 1 will control the moving direction of the first extension plate 3, thereby avoiding deviation in the moving position of the first extension plate 3.

[0024] A limit block 4 is connected to the outer surface of the first extension plate 3. A second extension plate 5 is slidably connected inside the movable shell 1. The first extension plate 3 will fix the position of the limit block 4. When the first extension plate 3 moves, it will drive the limit block 4 to move. The movable shell 1 will limit the moving direction of the second extension plate 5, so as to avoid deviation in the moving position of the second extension plate 5.

[0025] A blocking block 6 is connected to the outer surface of the second extension plate 5. A limit hole 7 is provided inside the first extension plate 3. A limiting mechanism 8 is provided inside the movable shell 1. The second extension plate 5 will fix the position of the blocking block 6. When the second extension plate 5 moves, it will drive the blocking block 6 to move. The inner side wall of the limit hole 7 is relatively smooth, and the friction force received by other objects when moving on the inner side wall of the limit hole 7 is small.

[0026] A support block 9 is connected to the outer surface of the movable shell 1. An adjusting rod 10 is connected inside the support block 9. The outer surface of the adjusting rod 10 is rotatably connected to a mounting plate 11. The movable shell 1 will fix the position of the support block 9, making the support block 9 unable to move. The position of the adjusting rod 10 is fixed through the support block 9. The mounting plate 11 can rotate around the adjusting rod 10. By rotating the mounting plate 11, it can better contact the surface of the steering column. Subsequently, the user can fix the mounting plate 11 on the surface of the steering column.

[0027] The limiting mechanism 8 includes an insertion plate 801. The outer surface of the insertion plate 801 is slidably connected to the inner wall of the limiting hole 7, and the outer surface of the insertion plate 801 is slidably connected to the inside of the movable housing 1. The insertion plate 801 can be inserted into the limiting hole 7. By inserting the insertion plate 801 into the inside of the limiting hole 7, the position of the first extension plate 3 is restricted, so that the first extension plate 3 cannot move up and down. The movable housing 1 will provide support for the insertion plate 801, so that the insertion plate 801 cannot move up and down. At the same time, the movable housing 1 will limit the direction in which the insertion plate 801 can move, thus preventing the position of the insertion plate 801 from deviating.

[0028] A transmission plate 802 is connected to the outer surface of the insertion plate 801. The outer surface of the transmission plate 802 is slidably connected to the inside of the movable housing 1. The insertion plate 801 will fix the position of the transmission plate 802. When the transmission plate 802 moves, it will drive the insertion plate 801 to move. The movable housing 1 will limit the direction in which the transmission plate 802 can move, thus preventing the position of the transmission plate 802 from deviating.

[0029] An insertion rod 803 is connected to the outer surface of the transmission plate 802. The outer surface of the insertion rod 803 is slidably connected to the inside of the movable housing 1. A connecting plate 804 is connected to the outer surface of the insertion rod 803. The transmission plate 802 will fix the position of the insertion rod 803. When the insertion rod 803 moves, it will drive the transmission plate 802 to move. The movable housing 1 will limit the direction of movement of the insertion rod 803 to prevent the position of the insertion rod 803 from deviating. The insertion rod 803 will fix the position of the connecting plate 804. When the connecting plate 804 moves, it will drive the insertion rod 803 to move. By moving the connecting plate 804, the two insertion rods 803 are driven to move simultaneously.

[0030] A spring 805 is connected to the outer surface of the transmission plate 802. The end of the spring 805 away from the transmission plate 802 is connected to the inside of the movable housing 1. The spring 805 is sleeved on the outer surface of the insertion rod 803. The spring 805 will provide a thrust for the transmission plate 802. When the first extension plate 3 moves to a suitable position and the user does not pull the insertion rod 803, the spring 805 will push the transmission plate 802 so that the insertion plate 801 is inserted into the limiting hole 7. The movable housing 1 will limit the position of the spring 805, and the insertion rod 803 will limit the position where the spring 805 can move, thus preventing the spring 805 from bulging too much to one side when compressed.

[0031] The outer surface of the limiting block 4 is slidably connected to the inner wall of the sliding groove 2. The outer surface of the limiting block 4 is connected to the outer surface of the second extension plate 5. The outer surface of the blocking block 6 is slidably connected to the inside of the first extension plate 3. The sliding groove 2 will limit the position where the limiting block 4 can move, so as to limit the positions where the first extension plate 3 and the second extension plate 5 can move. By closing the movable housing 1, the blocking block 6 is inserted into the inside of the first extension plate 3, so that when the position of the first extension plate 3 is restricted, the position of the second extension plate 5 will also be restricted.

[0032] An upper limit plate 12 is internally connected to the second extension plate 5. The outer surface of the upper limit plate 12 is in contact with the outer surface of the second extension plate 5. A lower limit plate 13 is installed inside the movable shell 1. The second extension plate 5 fixes the position of the upper limit plate 12, and separates the wire harness through the gap of the upper limit plate 12, so as to facilitate the user to observe the situation of the wire harness. The gap of the lower limit plate 13 can also separate the wire harness.
