[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0030] A telescopic lever includes a sleeve 1 and a telescopic rod 2 inserted into and slidably connected to the sleeve 1. The sleeve 1 is also covered by an outer sleeve 3, which covers the sleeve 1 to prevent dirt from entering the sleeve 1.

[0031] Both sides of the outer wall of the card sleeve 1 are provided with through grooves 11, the two through grooves 11 are mirrored, and a number of card slots 12 are arranged in an orderly manner on the through grooves 11, and the positions of each card slot 12 on the two through grooves 11 are corresponding.

[0032] The telescopic rod 2 is provided with a locking rod 3 that engages with the locking slot 12. The telescopic rod 2 is provided with an "L"-shaped stop groove 21, which includes an unlocking stop groove 22 and a locking stop groove 23. The locking rod 3 can switch between the unlocking stop groove 22 and the locking stop groove 23.

[0033] A tension spring 4 is provided between the locking lever 3 and the telescopic lever 2. The tension spring 4 always applies a force to the locking lever 3 to engage with the unlocking stop groove 22 or the locking stop groove 23.

[0034] Furthermore, a locking rod mounting seat 5 is provided at the bottom of the telescopic rod 2. The locking rod mounting seat 5 has a sliding groove 51. After the locking rod mounting seat 5 is inserted from the bottom of the telescopic rod 2, the position of the sliding groove 51 corresponds to the position of the "L"-shaped stop groove 21.

[0035] The clamp rod mounting base 5 is provided with a connecting rod 52 and a connecting sleeve 53. The connecting sleeve 53 is located in the slide groove 51 and moves within the slide groove 51. The connecting sleeve 53 is fitted onto the clamp rod 3. The two ends of the tension spring 4 are respectively connected to the connecting sleeve 53 and the connecting rod 52.

[0036] The connecting sleeve 53 has a groove 54, and the end of the tension spring 4 is fitted into the groove 54. The tension spring 4 is more stably connected to the connecting sleeve 53, preventing it from falling off.

[0037] Both sides of the telescopic rod 2 are provided with "L"-shaped stop grooves 21, and the "L"-shaped stop grooves 21 on both sides are mirrored. Both sides of the clamp rod mounting base 5 are provided with sliding grooves 51 corresponding to the "L"-shaped stop grooves 21.

[0038] When the mounting base 5 is inserted from the bottom of the telescopic rod 2, the telescopic rod 2 is inserted into the sleeve 1. The rod 3 passes through the through groove 11, the "L"-shaped stop groove 21 and the slide groove 51 in sequence, and then passes through the connecting sleeve 53. It extends out from the slide groove 51, the "L"-shaped stop groove 21 and the through groove 11 on the other side. That is, the two ends of the rod 3 are located in the through grooves 11 on both sides, making the telescopic rod 2 more stable when it is extended or retracted.

[0039] The two ends of the through groove 11 are respectively provided with a first pushing surface 13 and a second pushing surface 14 for pushing the locking rod 3. The first pushing surface 13 is located at the top of the through groove 11 and is used to push the locking rod 3 from the unlocking position groove 22 into the locking position groove 23. The second pushing surface 14 is located at the bottom of the through groove 11 and is used to push the locking rod 3 from the locking position groove 23 into the unlocking position groove 22.

[0040] When the locking lever 3 is in the locking position slot 23, push the telescopic rod 2 to make the locking lever 3 lock into each slot 12 step by step.

[0041] like Figure 6 As shown, the telescopic rod is in its longest position, and the locking lever 3 is in the locking stop groove 23. When the telescopic rod 2 is pushed, the entire telescopic rod will gradually shorten. During this process, the locking lever 3 will progressively engage with each of the corresponding slots 12. When the position is adjusted to the appropriate level, pushing the telescopic rod 2 stops, and the locking lever 3 is locked in the corresponding slot 12 (e.g., ...). Figure 2 As shown), continue pushing the telescopic rod 2. The telescopic rod 2 is pushed to its shortest state, and the locking rod 3 contacts the second pushing surface 14. The second pushing surface 14 pushes the locking rod 3 from the locking position groove 23 into the unlocking position groove 22 (as shown). Figure 8 As shown), in this position, the locking lever 3 will not engage with the locking slot 12. Pulling the telescopic lever 2 will extend it to its longest position. After the telescopic lever 2 is extended to its longest position, the locking lever 3 will contact the first pushing surface 13 again. The first pushing surface 13 will push the locking lever 3 into the locking position slot 23, returning it to its original position. Figure 6 The state shown.

[0042] This telescopic rod is generally used on angle adjustment components, such as when two components are rotatably connected. The telescopic rod is connected at the included angle between the two components, and the two components are held together by the telescopic rod.
