DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a bracket for conveniently fixing a lens, comprising a bracket 1, a placement groove 2 is opened on the top of the bracket 1, a lens 3 is fitted on the inner wall of the placement groove 2, an extrusion block 5 is slidably installed on the inner side of the bracket 1, an extrusion spring 6 is fixed on the side of the extrusion block 5 away from the lens 3, and the side of the extrusion spring 6 away from the extrusion block 5 is fixed to the inner side of the bracket 1, two groups of extrusion blocks 5 are provided, and the two groups of extrusion blocks 5 are symmetrically arranged with the center line of the bracket 1 in the vertical direction as the symmetry axis, by placing the lens 3 into the placement groove 2, the two groups of extrusion blocks 5 can pre-press and position the lens 3, a clamping mechanism 4 for quickly installing the lens 3 is provided on the bracket 1, and an adjustment mechanism 7 is provided on the clamping mechanism 4.

[0024] Specifically, the clamping mechanism 4 includes a slide 41, a slider 42, a connecting rod 43, a handle 44, a clamping block 45, a hinge block 46, a movable rod 47, a return spring 48 and a limit block 49; the slide 41 is opened at the top of the bracket 1, the inner wall of the slide 41 is slidably mounted with a slider 42, the front of the slider 42 is fixed with a connecting rod 43, the end of the connecting rod 43 away from the slider 42 is fixed with a handle 44, the inner wall of the placement slot 2 is slidably mounted with a clamping block 45, the clamping block 45 Two groups of clamping blocks 45 are provided, and the two groups of clamping blocks 45 are symmetrically arranged with the center line of the bracket 1 in the vertical direction as the symmetry axis. By providing two groups of clamping blocks 45, the lens 3 can be clamped and fixed. A movable rod 47 is hinged on the slider 42. The end of the movable rod 47 away from the slider 42 is hinged on the hinge block 46. The hinge block 46 is fixed on the clamping block 45. When it is necessary to clamp and fix the lens 3, the handle 44 can be pushed close to the placement slot 2, and the connecting rod 43 can be used to make the lens 3 The slider 42 squeezes the movable rod 47 to rotate at the hinge, so that the movable rod 47 squeezes the two groups of clamping blocks 45 away from each other, and then the lens 3 can be inserted into the placement groove 2, so that the extrusion block 5 pre-positions the lens 3 in the placement groove 2, and the side wall of the clamping block 45 is fixed with a return spring 48, and the side of the return spring 48 away from the clamping block 45 is fixed to the inner wall of the placement groove 2, and when the two groups of clamping blocks 45 are away from each other, the return spring 48 will be compressed. When the lens 3 is placed in the placement groove 2, by loosening the handle 44, the two groups of clamping blocks 45 can be brought close to each other because the return spring 48 is in a compressed state, and the lens 3 can be clamped and fixed by the clamping block 45, which is convenient for installing and fixing the lens 3. A limit block 49 is slidably installed on the inner side of the clamping block 45, and the bottom of the limit block 49 is in contact with the top of the lens 3. By setting the limit block 49, the top of the lens 3 can be limited, so that the installation stability is better.

[0025] Specifically, the adjustment mechanism 7 includes a connecting groove 71, a threaded rod 72, a knob 73 and a threaded sleeve 74. The connecting groove 71 is opened on the clamping block 45. The threaded rod 72 is rotatably installed on the inner wall of the connecting groove 71. The knob 73 is fixed on the top of the threaded rod 72. The outer wall of the threaded rod 72 is threadedly connected with a threaded sleeve 74. The threaded sleeve 74 is slidably installed on the inner wall of the connecting groove 71. The side wall of the threaded sleeve 74 is fixedly connected to the side wall of the limit block 49. By rotating the knob 73, the threaded rod 72 can be rotated, and the threaded sleeve 74 can be moved on the threaded rod 72, so that the height of the limit block 49 on the clamping block 45 can be adjusted, and the lenses 3 of different heights can be limited.

[0026] Working principle: when it is necessary to clamp and fix the lens 3, the handle 44 can be pushed closer to the placement groove 2, and the slider 42 can be used to squeeze the movable rod 47 and rotate at the hinge through the connecting rod 43, so that the movable rod 47 squeezes the two groups of clamping blocks 45 away from each other, and then the lens 3 can be inserted into the placement groove 2, so that the squeezing block 5 pre-positions the lens 3 in the placement groove 2, and when the two groups of clamping blocks 45 are away from each other, the reset spring 48 will be compressed. When the lens 3 is placed in the placement groove 2, by loosening the handle 44, the reset spring 48 is in a compressed state, and the two groups of clamping blocks 45 can be brought closer to each other. The lens 3 can be clamped and fixed by the clamping block 45, which is convenient for installing and fixing the lens 3. When it is necessary to remove the lens 3 from the bracket 1, the handle 44 can be continued to be pushed, and the two groups of clamping blocks 45 can be moved away from each other through the slider 42, the movable rod 47 and the hinge block 46, thereby releasing the clamping fixation of the lens 3 and facilitating the removal of the lens 3.

[0027] By turning the knob 73, the threaded rod 72 can be rotated, and the threaded sleeve 74 can be moved on the threaded rod 72, so that the height of the limit block 49 on the clamping block 45 can be adjusted, and the lenses 3 of different heights can be limited.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
