[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figure 1 The present invention provides a sample preparation device, comprising: a sample preparation device body 1, an installation structure 3, and a replacement structure 4.

An anti-slip sleeve 8 is installed on the arc surface of the moving handle 7 via the replacement structure 4. A moving column 5 is fixedly connected to the lower surface of the moving device 2. A cutting plate 6 is installed on the lower surface of the moving column 5 via the installation structure 3. The installation structure 3 is provided inside the moving column 5. The replacement structure 4 is provided on the inner wall of the moving handle 7.

[0028] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The installation structure 3 includes a fixed frame 301, a connecting groove 311, two mounting grooves 307, and a connecting column 312. The fixed frame 301 is fixedly connected to the movable column 5. The connecting groove 311 is formed on the movable column 5. Both mounting grooves 307 are formed on the movable column 5 and are interconnected with the connecting groove 311. The connecting column 312 is fixedly connected to the cutting plate 6 and is slidably connected to the connecting groove 311. The inner wall of the connecting column 312 has a positioning groove 309. Two arc surfaces of the connecting column 312 are fixedly connected to the connecting groove 311. A limiting plate 308 is slidably connected to the mounting groove 307. A moving rod 304 is slidably connected to the inner wall of the fixing frame 301. A locking plate 313 is fixedly connected to one end of the moving rod 304 near the moving column 5. The locking plate 313 is slidably connected to the moving column 5 and to the positioning groove 309. A spring 305 is sleeved on the arc surface of the moving rod 304. The two ends of the spring 305 are fixedly connected to the fixing frame 301 and the locking plate 313 respectively. A connecting plate 303 is fixedly connected to one end of the moving rod 304 away from the moving column 5. When personnel need to install the cutting plate 6 on the moving column 5, they can move the cutting plate 6 until the connecting column 312 slides into the inner wall of the connecting groove 311 and the clamping plate 313 slides into the inner wall of the positioning groove 309. This allows personnel to quickly and easily install the cutting plate 6 on the moving column 5, improving installation efficiency. A handle 306 is fixedly connected to the side of the connecting plate 303 away from the moving rod 304. The handle 306 is U-shaped. The handle 306 facilitates the movement of the connecting plate 303, improving ease of operation. Two limiting rods 302 are slidably connected to the inner wall of the fixing frame 301, and the two limiting rods 302 are fixedly connected to the clamping plate 313. The limiting rods 302 can limit the clamping plate 313, improving its stability during movement. A guide block 310 is fixedly connected to the upper end of the limiting plate 308, and the guide block 310 is slidably connected to the mounting groove 307. The guide block 310 can guide the limiting plate 308, making it easier for personnel to slide the limiting plate 308 into the inner wall of the mounting groove 307; In the embodiments of this utility model, please refer to Figure 4 and Figure 5The replacement structure 4 includes two connecting grooves 42, a fixing ring 41, and an auxiliary rod 47. Both connecting grooves 42 are opened on the moving handle 7. The fixing ring 41 is fixedly connected to the moving handle 7, and the auxiliary rod 47 is fixedly connected to the moving handle 7. The fixing ring 41 abuts against the anti-slip sleeve 8. The inner wall of the connecting groove 42 is slidably connected to the mounting plate 43. The two mounting plates 43 are fixedly connected to the anti-slip sleeve 8. The arc surface of the auxiliary rod 47 is rotatably connected to the baffle 49. The arc surface of the auxiliary rod 47 is fitted with a coil spring 48. The two ends of the coil spring 48 are fixedly connected to the baffle 49 and the auxiliary rod 47, respectively. The inner wall of the baffle 49 is opened with two auxiliary grooves 44. The auxiliary grooves 44 are adapted to the size of the mounting plate 43. Two auxiliary blocks 45 are fixedly connected to the side of the baffle 49 away from the moving handle 7. When the anti-slip sleeve 8 needs to be replaced after prolonged use, personnel can rotate the auxiliary block 45 until the auxiliary groove 44 aligns with the connecting groove 42. Then, personnel can move the anti-slip sleeve 8 until the mounting plate 43 slides out of the inner wall of the connecting groove 42 and the auxiliary groove 44, thus facilitating the replacement of the anti-slip sleeve 8 and improving replacement efficiency. The inner wall of the auxiliary block 45 has several anti-slip grooves 46 evenly distributed on it. The anti-slip grooves 46 increase the friction between the personnel's hands and the auxiliary block 45, preventing slippage during movement. The baffle 49 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the baffle 49 during short-term use. The working principle of the sample preparation device provided by this utility model is as follows: When a person needs to install the cutting plate 6 on the moving column 5 for use, the person can first move the cutting plate 6. The cutting plate 6 drives the connecting column 312 to move closer to the moving column 5. The connecting column 312 drives the two limiting plates 308 to move closer to the moving column 5. The limiting plates 308 drive the guide block 310 to move closer to the moving column 5. The guide block 310 can guide the limiting plate 308, making it convenient for the person to slide the limiting plate 308 into the inner wall of the mounting groove 307, until the connecting column 312 slides into the inner wall of the connecting groove 311, the guide block 310 and the limiting plate 308 slide into the inner wall of the mounting groove 307. During the process of the connecting column 312 sliding in the inner wall of the connecting groove 311, the connecting column 312 will abut against the inclined surface of the clamping plate 313. Then the connecting column 312 will drive the clamping plate 313 away from the connecting groove 311. When the column 312 moves, the clamping plate 313 will drive the moving rod 304 and the two limiting rods 302 to move away from the connecting column 312. The clamping plate 313 will also drive the spring 305 to retract. The limiting rods 302 can limit the clamping plate 313, which can improve the stability of the clamping plate 313 during movement. Then the moving rod 304 will drive the connecting plate 303 to move away from the connecting column 312. The connecting plate 303 will drive the handle 306 to move away from the connecting column 312. The handle 306 can facilitate the movement of the connecting plate 303 by the personnel, which can improve the convenience of operation. Until the upper end of the connecting column 312 abuts against the top wall of the connecting groove 311, and at this time the positioning groove 309 corresponds to the clamping plate 313, the spring 305 will rebound, causing the clamping plate 313 to move closer to the positioning groove 309 until the clamping plate 313 slides into the inner wall of the positioning groove 309.

[0029] In addition, when personnel need to replace the anti-slip sleeve 8, they can first rotate it using two auxiliary blocks 45. The anti-slip grooves 46 on the inner wall of the auxiliary blocks 45 can increase the friction between the personnel's hands and the auxiliary blocks 45, preventing slippage during movement. Then, the two auxiliary blocks 45 drive the baffle 49 to rotate. The baffle 49 is made of stainless steel, which has high strength and good wear resistance, preventing deformation during short-term use. The baffle 49 then drives the coil spring 48 to retract until the auxiliary groove 44 corresponds to the connecting groove 42. Then, the personnel move the anti-slip sleeve 8 away from the fixing ring 41. The anti-slip sleeve 8 drives the two mounting plates 43 away from the fixing ring 41 until the mounting plates 43 completely slide out of the inner wall of the connecting groove 42 and the auxiliary groove 44.

[0030] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
