[0008] In an embodiment of the present utility model, the step adjustment part includes a connecting upper lifting plate. Both sides of the connecting upper lifting plate are rotatably connected inside the housing through rotating shafts. One end of the connecting upper lifting plate is fixed with a pressing plate, and the end of the connecting upper lifting plate is located below one end of the step clamping plate.

[0009] In an embodiment of the present utility model, a notch groove matching the connecting upper lifting plate is formed on the housing. The connecting upper lifting plate penetrates through the notch groove and extends to the outside, and the pressing plate is located outside the housing.

[0010] In an embodiment of the present utility model, an upper lead screw sliding sleeve is fixedly penetrated through the upper part of the housing, and a lower lead screw sliding sleeve is fixedly penetrated through the lower part of the housing.

[0023] Please refer to Figures 1-4 , the pressing structure 200 includes a housing 210, a support member 220, a stepping adjustment part 230, a stepping clamping plate 260, and a quick-release adjustment part 290. The housing 210 is slidably and telescopically sleeved on the smooth rod 100. One side inside the housing 210 is fixed with a limit plate 213. The support member 220 is fixed inside the housing 210. The stepping adjustment part 230 is rotatably connected inside the housing 210. The stepping clamping plate 260 is sleeved on the smooth rod 100. One end of the stepping clamping plate 260 is located above the stepping adjustment part 230. The stepping clamping plate 260 is clamped on the limit plate 213. A stepping spring 270 and a quick-release spring 280 are also sleeved on the smooth rod 100. The stepping spring 270 is located above the stepping clamping plate 260. The quick-release adjustment part 290 is installed at the bottom of the housing 210 and acts on the quick-release spring 280.

[0024] The support member 220 includes a vertical plate 221 and an intermediate lead plate 222. The vertical plate 221 is fixed to the inner top surface of the housing 210. The intermediate lead plate 222 is fixed to the vertical plate 221. The intermediate lead plate 222 is sleeved on the smooth rod 100. The quick-release spring 280 is located below the intermediate lead plate 222. The stepping clamping plate 260 is located above the intermediate lead plate 222. Here, the intermediate lead plate 222 can support the stepping clamping plate 260. The stepping adjustment part 230 includes a connecting and lifting plate 231. Both sides of the connecting and lifting plate 231 are rotatably connected inside the housing 210 through a rotating shaft 233. One end of the connecting and lifting plate 231 is fixed with a pressing plate 232. The end of the connecting and lifting plate 231 is located below one end of the stepping clamping plate 260. Here, by pressing down the pressing plate 232, the end of the connecting and lifting plate 231 is lifted upward with the rotating shaft 233 as the center, so that the stepping clamping plate 260 moves upward and is limited by the limit plate 213 while squeezing the stepping spring 270, thereby increasing the downward pressure and the friction between the quick-release plate 293 and the smooth rod 100 for pressing. A notch groove 211 matching the connecting and lifting plate 231 is opened on the housing 210. The connecting and lifting plate 231 extends through the notch groove 211 to the outside. The pressing plate 232 is located outside the housing 210. The notch groove 211 can facilitate the external installation of the connecting and lifting plate 231.

[0025] An upper lead sleeve 240 is fixedly penetrated through the upper part of the housing 210, and a lower lead sleeve 250 is fixedly penetrated through the lower part of the housing 210. The upper lead sleeve 240 and the lower lead sleeve 250 are slidably sleeved on the smooth rod 100. Here, the upper lead sleeve 240 and the lower lead sleeve 250 can improve the stability of the up and down movement.

[0026] The quick-release adjusting part 290 includes a quick-release sliding sleeve 291 and a quick-release plate 293. The quick-release sliding sleeve 291 is fixedly penetrated at the bottom of the housing 210. A connecting column 292 is slidably connected inside the quick-release sliding sleeve 291.

The quick-release plate 293 is sleeved on the optical rod 100. Here, the quick-release spring 280 is located above the quick-release plate 293. By pressing the connecting column 292 upward through the quick-release button 294, one end of the quick-release plate 293 will move upward, thereby squeezing the quick-release spring 280, reducing the friction between the quick-release plate 293 and the optical rod 100, and enabling the pressing structure 200 to move up and down.

[0027] A lifting block 212 is fixed inside the housing 210. One end of the quick-release plate 293 is located on the lifting block 212. The setting of the lifting block 212 can lift one end of the quick-release plate 293 upward, so that the quick-release plate 293 is in an inclined state, and the friction with the optical rod 100 is increased under the action of the quick-release spring 280. Through holes matching the optical rod 100 are opened inside the stepping clamping plate 260, the intermediate lead screw plate 222 and the quick-release plate 293. The setting of the through holes is used for connection and installation.

[0028] Specifically, the working principle of the stepping pressing and quick-release device: When in use, the connecting upper picking plate 231 is pressed downward by the pressing plate 232, and one end of the connecting upper picking plate 231 is lifted upward with the rotation axis 233 as the center, so that the stepping clamping plate 260 moves upward to compress the stepping spring 270, and is clamped and limited by the limiting plate 213. The stepping clamping plate 260 realizes stepping pressing due to the frictional clamping force with the optical rod 100. In this process, the quick-release spring 280 locks the optical rod 100 through the quick-release plate 293 to achieve double insurance. When the stepping adjusting part 230 is pressed down, its stepping spring 270 is compressed, and the elasticity of the stepping spring 270 is utilized to increase the friction between the quick-release plate 293 and the optical rod 100 to realize the stepping pressing process; when quick release or quick disassembly is required, by pressing the quick-release button 294, the quick-release plate 293 is lifted. When the quick-release plate 293 is horizontal and concentric with the optical rod 100, the friction is reduced, and the quick-release process is realized. In this way, during the use process, the double-spring alternately acts on the double cards to realize stepping pressing and the function of quick movement, and through reasonable structural design in a small space, the product is made small and mass-produced. It not only realizes the functions of stepping pressing and quick disassembly, but also greatly reduces the labor intensity of scientific research personnel and saves the time for replacing the sieve frame, making it more user-friendly.
