The end surface is distributed vertically, and the connecting plate 4 is distributed vertically to the bottom surface of the test bench 2, which makes the test bench more stable. Arc holes are provided on the front and rear sides of the bottom plate 1, and the top edges of the bottom plate 1 are smooth curved surfaces, and an anti-slip groove is provided on the bottom surface of the bottom plate 1, which reduces the material used and reduces the investment cost. The second limit plate 9 is located on the side of the pulling handle 12 just above the first limit plate 8, and the second limit plate 9 is distributed vertically to the bottom surface of the test bench 2. When the connecting rope 10 is moved under force, it will not rub the side of the first limit plate 8; when the test bench 2 needs to be raised, the personnel first hold the middle of both sides of the test bench 2 with both hands, and then pull the pulling handle 12 to one side with their fingers, and the pulling handle 12 slides along the inner side of the slide groove 11, and at the same time When the pull handle 12 is pulled under the limiting action of the second limiting plate 9 and the first limiting plate 8, the T-shaped block 6 is driven to move horizontally through the connecting rope 10. At this time, the limiting spring 7 is forced to open. When the T-shaped block 6 moves, it drives the latch 15 to leave the inner side of the groove 13, so that the latch 15 and the rack 14 are no longer engaged with each other. Then, the personnel lifts the test bench 2 with force, so that the connecting plate 4 moves along the vertical plate 3. When the test bench 2 reaches a suitable height, the personnel releases the pulling handle 12. At this time, the limiting spring 7 is not forced to shrink and drives the T-shaped block 6 back to its original position, so that the T-shaped block 6 drives the latch 15 to be inside the groove 13 and engage with the rack 14, so that the vertical plate 3 and the connecting plate 4 are fixed, thereby completing the adjustment of the height of the test bench 2;The height of the existing laboratory test bench is fixed and cannot be adjusted. When workers of different heights use the test bench, they bend to different degrees, which causes waist pain. It is not suitable for people of different heights and has poor practicality. By designing the base plate 1, the test bench 2, and the lifting assembly, when workers of different heights use the laboratory test bench, they can adjust the height of the test bench according to their own height, so that the waist bending degree is small, avoiding the waist pain caused by long-term bending, making the workers more comfortable when using the test bench, and the overall structure is simple and practical. ;
