All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027]

First Embodiment

[0028] Refer to Figure 1 , which is a schematic structural diagram of an angle adjustment device 100 provided in the first embodiment of the present invention. The angle adjustment device 100 includes, for example: a mounting portion 10, a fixing portion 20, an adjustment shaft 30, and a linkage shaft 40. Among them, refer to Figure 2 , the mounting portion 10 is provided with a mounting panel and a first side plate 11 connected to one side of the mounting panel; the first side plate 11 is provided with a first adjustment hole 12; the fixing portion 20 is provided with a second side plate 21, and the second side plate 21 is provided with a second adjustment hole 22; when the second side plate 21 and the first side plate 11 are staggered and matched, the first adjustment hole 12 and the second adjustment hole 22 form an intersection position; the linkage shaft 40 is inserted through the intersection position and is provided with a first threaded connection member 41; the adjustment shaft 30 is provided with a second threaded connection member 31 that cooperates with the first threaded connection member 41; when the adjustment shaft 30 rotates, the second threaded connection member 31 and the first threaded connection member 41 cooperate, and the linkage shaft 40 moves along the second adjustment hole 31 to change the intersection position.

[0029] For example, the first side plate 11 and the second side plate 21 can be respectively a thick steel plate to meet the strength requirements for the movement of the linkage shaft 40 along the adjustment hole 31; the first side plate 11 and the second side plate 21 can be arranged in a fitting manner or at an interval. When the first side plate 11 and the second side plate 21 can be arranged in a fitting manner, the adjustment shaft 30 is located on both sides of the first side plate 11 and the second side plate 21; when the first side plate 11 and the second side plate 21 are arranged at an interval, the adjustment shaft 30 can also be located between the first side plate 11 and the second side plate 21.

[0030] Preferably, refer to Figure 3, wherein, one of the first side plates 11 is transparently displayed, so as to display that the first adjustment hole 12 and the second adjustment hole 22 are in a cross structure; on the side of the fixing part 20 close to the mounting part 10, there is an inclined surface 50 inclined to the fixing part 20, so as to increase the adjustable range of the angle of the angle adjusting device 100. For example, when the mounting part 10 inclines towards the fixing part 20, the fixing part 20 has a first end close to the mounting part 10 and a second end far from the mounting part 10. When the mounting part 10 contacts the first end, the included angle between the mounting part 10 and the fixing part 20 is the largest. That is, adding the inclined surface 50 can increase the maximum included angle between the mounting part 10 and the fixing part 20, so as to increase the adjustable range of the angle of the angle adjusting device 100.

[0031] Further, referring to Figure 4 , the first threaded connector 41 is a threaded hole, and the second threaded connector 31 is a screw rod matching with it; the adjusting shaft 30 is also provided with an adjusting opening 32 at one end of the screw rod. For example, the adjusting shaft 30 is fixed and can only rotate around its own axis.

[0032] Furthermore, the mounting part 10 is provided with two opposite first side plates 11. Correspondingly, the fixing part 20 is provided with two opposite second side plates 21; wherein, the two second side plates 21 are located between the two first side plates 11. For example, a receiving space is formed between the two first side plates 11 and the mounting panel, and the receiving space is used to receive the fixing part 20.

[0033] Preferably, both ends of the linkage shaft 40 respectively extend out of the two first side plates 11; wherein, one end of the linkage shaft 40 is connected with a baffle 42, and the other end is provided with a groove 43; the angle adjusting device 100 further includes: a retaining ring 60, which is clamped in the groove 43; wherein, the baffle 42 and the retaining ring 60 limit the linkage shaft 40 at the crossed position. For example, the baffle 42 can be welded on the linkage shaft 40 or integrally formed with the linkage shaft 40; the retaining ring 60 can be an annular sheet made of an elastic member such as rubber, or an annular sheet made of aluminum alloy, stainless steel or plastic.

[0034] Preferably, the linkage shaft 40 and the adjusting shaft 30 are cooperatively arranged between the two second side plates 21. For example, the linkage shaft 40 and the adjusting shaft 30 can be made of carbon steel, stainless steel or copper.

[0035] Preferably, referring to Figure 5, the angle adjustment device 100 further includes, for example: a limit block 70. The limit block 70 is disposed between the fixed portion 20 and the mounting portion 10, and is detachably connected to the first side plate 11 and the second side plate 21. For example, the limit block 70 fixes the adjustment shaft 30, such that the adjustment shaft 30 can only rotate about its own axis. An adjustment through hole 71 is provided at a position corresponding to the adjustment shaft 30 on the limit block 70. The adjustment shaft 30 can be adjusted through the adjustment through hole 71 to rotate about its own axis, so that the linkage shaft 40 moves up and down along the adjustment shaft 30.
