[0024] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0025] Example 1
[0026] Please refer to Figure 1This embodiment provides a novel support device comprising: a telescopic rod, a first positioning and locking mechanism 4, and a second positioning and locking mechanism 5. The telescopic rod, from the outside to the inside, consists of a sleeve 1, a first telescopic rod 2, and a second telescopic rod 3. The first telescopic rod 2 cannot be fully pulled out of the sleeve 1 from above, and the second telescopic rod 3 cannot be fully pulled out of the first telescopic rod 2 from above. The first telescopic rod 2 and the sleeve 1 are locked and limited by the first positioning and locking mechanism 4, and the first telescopic rod 2 and the second telescopic rod 3 are locked and limited by the second positioning and locking mechanism 5. The tightening mechanism 5 is used for locking, and the lower support plate is fixed at the lower end of the sleeve 1 and the upper support plate is fixed at the upper end of the second telescopic rod 3. The lower support plate and the upper support plate have the same structure, both being support plates 24. As a preferred structure, two opposing bolt plates 14 are fixed at the upper end of the lower support plate and the lower end of the upper support plate. The lower end of the sleeve 1 and the upper end of the second telescopic rod 3 are respectively inserted between the two bolt plates 14 and fixed by bolts and nuts. In this way, the angle between the lower support plate and the upper support plate can be varied.
[0027] Please refer to Figure 2 The first positioning and locking mechanism 4 includes a sleeve 21 and a clamp 22 integral with the sleeve 21. The sleeve 21 is fixed to the sleeve 1. The clamp 22 has a notch that cuts through one side of the clamp 22, and clamping plates 23 perpendicular to the notch are fixed at both ends of the notch. The two clamping plates 23 are fixed together by bolts and nuts, so that the diameter of the clamp 22 can be adjusted. In order to increase the clamping effect, a spring is also provided between the two clamping plates 23, and the spring is sleeved on the bolt.
[0028] Please refer to Figure 3The aforementioned second positioning and locking mechanism 5 includes a locking seat 6, which is divided into an upper seat 8 and a lower seat 9 by a partition 7. The lower seat 9 is fixed to the first telescopic rod 2, and a first spring 10 is sleeved on the second telescopic rod 3 inside the lower seat 9. The lower end of the first spring 10 is a first limiting plate 11 sleeved on the second telescopic rod 3. The first limiting plate 11 is tilted and locked to the second telescopic rod 3 by the elastic force of the first spring 10. One end of the first limiting plate 11 is inserted into the lower seat 9, and the other end extends out of the lower seat 9. At the same time, the lower seat 9 at the insertion end of the first limiting plate 11 is also provided with a moving groove 12 with a height greater than the height of the first limiting plate 11. The upper seat 8 is provided with a grip-type short-distance adjustment device 13, which is controlled by a second spring 16. The device consists of a second limiting plate 17 and a handle 18. A second spring 16 is sleeved on the second telescopic rod 3 inside the upper seat 8. The second limiting plate 17 is located below the second spring 16 and is sleeved on the second telescopic rod 3 inside the upper seat 8. The handle 18 is hinged to the upper seat 8. A top rod 25 is fixed on the handle 18. The top rod 25 abuts against the lower end of the second limiting plate 17. The second limiting plate 17 is initially in a horizontal state and does not limit the second telescopic rod 3. When in use, the first limiting plate 11 needs to be pushed up first to make the first limiting plate 11 horizontal. Then, by pressing the handle 18 and the reset ability of the second spring 16, the second limiting plate 17 will switch back and forth between the tilted and horizontal states, which will drive the second telescopic rod 3 to move up a small distance.
[0029] Continuing the explanation, the above structure is still quite cumbersome to use. Therefore, as a preferred structure, the first limiting plate 11 is set horizontally, the locking seat 6 has a pressing groove that is opposite to the moving groove 12 and is higher than the moving groove 12, and the partition plate 7 is screwed with a screw 15. By rotating the screw 15, the screw 15 moves down to hold the first limiting plate 11 firmly. Finally, the two ends of the first limiting plate 11 are tilted in the pressing groove and the moving groove 12 to securely limit the second telescopic rod 3. The advantage of this design is that the locking force can be controlled by the screw 15 during use. When the locking force is appropriate, the second telescopic rod 3 will not move down even in a vertical state, and the grip-type short-distance adjustment device 13 can drive the second telescopic rod 3 to move up, so it can be operated with one hand.
[0030] As a preferred structure, the grip-type short-distance adjustment device 13 also includes a high positioning block 19 and a low positioning block 20. The high positioning block 19 and the low positioning block 20 are arranged opposite to each other on the upper end of the partition 7. The high positioning block 19 is blocked by one side of the second limiting plate 17, and the low positioning block 20 is blocked by the top rod 25 at the lower end of the other side of the second limiting plate 17. The height of the low positioning block 20 plus the height of the top rod 25 is equal to the height of the high positioning block 19.
