For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] refer to Figure 1-4, shows a multi-axis adjustable connection device, comprising a first mounting seat 1, a second mounting seat 2 and a third mounting seat 3 arranged in sequence; the first mounting seat 1 can be connected to a bracket, and the optical instrument can be fixed on the third mounting seat 3;

[0025] The second mounting seat 2 is hinged to the first mounting seat 1 through a horizontally arranged first rotating shaft 11. A first tension spring 12 is arranged between the first mounting seat 1 and the second mounting seat 2. The first tension spring 12 applies an elastic force to the second mounting seat 2 to rotate around the first rotating shaft 11. The first mounting seat 1 is provided with a first push member 4 whose position can be adjusted. The first push member 4 is used to push the second mounting seat 2 to resist the elastic force of the first tension spring 12.

[0026] The third mounting seat 3 is hinged on the second mounting seat 2 through a second rotating shaft 21, and the axis of the second rotating shaft 21 is perpendicular to the axis of the first rotating shaft 11; a second tension spring 22 is provided between the second mounting seat 2 and the third mounting seat 3, and the second tension spring 22 applies an elastic force to the third mounting seat 3 to rotate around the second rotating shaft 21; a second pushing member 5 with adjustable position is provided on the third mounting seat 3, and the second pushing member 5 is used to push the second mounting seat 2 to resist the elastic force of the second tension spring 22.

[0027] In other words, when the optical instrument is fixed on the third mounting seat 3, by adjusting the position of the first pushing member 4 on the first mounting seat 1, the first pushing member 4 pushes the second mounting seat 2, so that the second mounting seat 2 rotates around the first rotating shaft 11. At this time, the first tension spring 12 makes the second mounting seat 2 always abut against the first pushing member 4, so that the second mounting seat 2 can be stably swung around the first rotating shaft 11, that is, the optical instrument can be swung forward and backward; similarly, by adjusting the position of the second pushing member 5 on the third mounting seat 3, since the second mounting seat 2 is fixed in the circumferential direction of the second rotating shaft 21, the third mounting seat 3 rotates around the second rotating shaft 21 under the thrust of the second pushing member 5, so that the optical instrument can be swung left and right. In this way, the spatial position adjustment of the optical instrument can be easily realized.

[0028] In some specific embodiments, to further facilitate operation, refer to Figure 2 and Figure 3The first push member 4 is threadedly connected to the first mounting seat 1, and one end of the first push member 4 abuts against the second mounting seat 2; the second push member 5 is threadedly connected to the third mounting seat 3, and one end of the second push member 5 abuts against the second mounting seat 2. In this way, by rotating the first push member 4 and the second push member 5, the optical instrument can be adjusted to swing forward and backward or left and right.

[0029] Specifically, in order to facilitate the arrangement of the second push member 5, refer to Figure 3 A protrusion 31 is protruded from the third mounting seat 3 in the direction of the second mounting seat 2, and the protrusion 31 is located on the side of the second mounting seat 2.

In this embodiment, after adjusting the position of the second mounting seat 2, the first locking member 6 can be rotated so that the first locking member 6 tightens the second mounting seat 2 in the direction of the first mounting seat 1 to ensure that the second mounting seat 2 abuts against the first push member 4; even if affected by external vibration factors, the second mounting seat 2 will not shake.

[0031] In some specific embodiments, reference Figure 1-3 , the third mounting seat 3 is provided with two protrusions 31, and the two protrusions 31 are respectively located on both sides of the second mounting seat 2; it also includes a second locking member 7, the second locking member 7 is threadedly connected to the protrusion 31, and the end of the second locking member 7 abuts against the side wall of the second mounting seat 2; the second locking member 7 and the second pushing member 5 are respectively located on both sides of the second mounting seat 2. In this embodiment, after adjusting the position of the third mounting seat 3, the second locking member 7 can be rotated, and the second locking member 7 can be used to tighten the second mounting seat 2 against the second pushing member 5 to ensure that the second mounting seat 2 does not shake.

[0032] In some specific embodiments, reference Figure 1-3, the first mounting seat 1 is fixedly connected with a fourth mounting seat 8, and the fourth mounting seat 8 is provided with a vertically opened connection hole 81.
