[0027] Need to explain: by erecting close focus telescope 2 outside experiment box 1, during use, the staff can hold close focus telescope 2, when the staff exerts vertical force, can drive vertical sliding sleeve 311 to slide on support vertical pole 31, when the staff exerts lateral force, can drive lateral sliding sleeve 321 to slide on support lateral pole 32, so that the position of close focus telescope 2 vertical plane can be adjusted;

[0028] Then the driving force of rotation can be applied to the support tube 33, at this time the support tube 33 can drive the spherical inner sleeve 34 to rotate in the spherical outer sleeve 323, so that the inclination angle of the close focus telescope 2 can be adjusted, so that the close focus telescope 2 can be moved to the desired position and adjusted to the desired angle, so that the staff can watch the state of the article during the experiment more conveniently;

[0029] It should be noted that: since the close focus telescope 2 is clamped and installed in the support assembly 3, during the subsequent use, the close focus telescope 2 can be removed, a camera can be installed in the support assembly 3, and the camera can be electrically connected with the controller in the experiment box 1, at this time the staff can watch the picture inside the test box through the display in the controller in real time, so that the flexibility of the staff can be further improved.

[0030] In the embodiment of the present application, please refer to Figures 1 to 4 , a plurality of annularly distributed support pieces 331 are fixedly installed in the inside of the support tube 33, the positions of the support pieces 331 correspond to the positions of the clamping pieces 334, the corresponding support pieces 331 and clamping pieces 334 are erected with fixedly connected springs 332 and telescopic rods 333, and the two ends of the springs 332 and telescopic rods 333 are fixedly connected with the corresponding support pieces 331 and clamping pieces 334, the outer wall of the clamping piece 334 is beveled, a threaded driving cylinder 35 is sleeved on the outer wall of the support tube 33, and the end of the driving cylinder 35 abuts against and is slidingly connected with the outer wall of the clamping piece 334.

[0031] It should be noted that: by the setting of the driving cylinder 35, during use, when the staff holds the support cylinder and controls the rotation of the driving cylinder 35, the driving cylinder 35 can move on the outer wall of the support cylinder, and when the end of the driving cylinder 35 abuts against the outer wall of the clamping piece 334, the beveled structure of the side wall of the clamping piece 334 can convert the moving force of the driving cylinder 35 into the driving force of the clamping piece 334, so that the plurality of clamping pieces 334 can smoothly move to the center, so that the plurality of clamping pieces 334 can smoothly clamp and fix the close focus telescope 2 or the camera placed inside, so that the close focus telescope 2 or the camera can be stably located outside the experiment box 1;

[0032] And through the setting of the spring 332, when the near-focus telescope 2 or the camera needs to be disassembled in the later period, when the control driving cylinder 35 is reversely rotated to release the extrusion on the clamping plate, the spring 332 drives the clamping pieces 334 through the action force of the spring 332, so that the plurality of clamping pieces 334 can move outward, and therefore the near-focus telescope 2 or the camera can be conveniently taken out by the staff.

[0033] In the embodiment of the utility model, please refer to Figures 1 to 4 The side wall of the experiment box body 1 is provided with a hinged box door 11, the inside of the box door 11 is inlaid with a fixed transparent glass 111, and the outer wall of the box door 11 is fixedly connected with the end of the supporting vertical rod 31.

[0034] It should be noted that: through the setting of the transparent glass 111, the fixed near-focus telescope 2 or camera in the supporting assembly 3 can be smoothly observed through the transparent glass 111 to watch the state of the items inside the experiment box body 1.

[0036] It should be noted that: through the setting of the rubber sleeve to increase the friction, the phenomenon that the vertical sliding sleeve 311 randomly slides on the supporting vertical rod 31, the horizontal sliding sleeve 321 randomly slides on the supporting horizontal rod 32, and the spherical inner sleeve 34 randomly rotates in the spherical outer sleeve 323 can be reduced, and therefore the stability of the supporting assembly 3 in supporting the external near-focus telescope 2 can be improved.

[0038] When using the device, the required experimental items can be placed in the experiment box body 1 for experimental operation, and when the staff wants to watch the state of the experimental items during the experiment, the near-focus telescope 2 can be held, and then the vertical sliding sleeve 311 and the horizontal sliding sleeve 321 can be adjusted according to the needs, so that the position of the external near-focus telescope 2 on the vertical plane can be adjusted.

[0039] After the adjustment of the position is completed, the near-focus telescope 2 can be held and rotated, so that the spherical inner sleeve 34 drives the near-focus telescope 2 to rotate inside the spherical outer sleeve 323, so that the inclination angle of the near-focus telescope 2 can be adjusted, and therefore the worker can watch the state of the experimental articles in the experimental box 1 through the near-focus telescope 2 at a required angle, without stopping the machine to take out the articles to watch, and the portability of the worker watching can be improved;

[0040] In the use process, the near-focus telescope 2 can also be taken out, the camera is clamped and fixed between the plurality of clamping pieces 334, after the clamping and fixing of the camera are completed, the camera can be electrically connected with the controller in the experimental box 1, and therefore in the subsequent use process, the worker can watch the state of the experimental articles in the experimental box 1 through the display on the controller in real time, and the flexibility of the worker watching the experimental articles can be further improved.
