A pull block 8 is installed on the surface of the slider 7. After the operating rod 3 is moved upward to a certain height, the slider 7 is driven to move outward by the pull block 8, so that the slider 7 extends out of the side groove 6. After the operating rod 3 is released, the spring 5 drives the clamping plate 4 to move downward, drives the operating rod 3 to move downward, and the slider 7 is stuck on the top of the fixing frame 2 to prevent the clamping plate 4 from continuing to move downward, so that the cutting piece can be placed at the bottom of the clamping plate 4.

[0020] As a preferred solution, further, two inner sliding rods 9 are installed at the opposite ends of the two sliders 7, and the four inner sliding rods 9 are arranged opposite to each other in pairs.

A limiting block 11 is installed on the surface of the inner sliding rod 9, and the limiting block 11 is slidably installed in the limiting groove. The limiting block 11 is slidably installed in the limiting groove to prevent the slider 7 from moving too much out of the side groove 6, causing the slider 7 to completely extend out of the side groove 6.

[0021] As a preferred solution, further, a top block 12 is installed at the top of the operating rod 3, a handle 13 is installed at the top of the top block 12, and handles 2 14 are installed at the opposite ends of the two fixing frames 2. By using handles 2 14, the work surface 1 can be easily driven to rotate.

[0022] As a preferred solution, further, a rotating shaft 15 is installed on the middle side of the bottom of the work table 1, and a base 16 is installed on the bottom of the rotating shaft 15. The rotating shaft 15 and the base 16 are rotatably connected through a bearing. The rotating shaft 15 is used to rotate the work table 1 on the top of the base 16 to facilitate changing the cutting direction of the cutting piece; support plates 17 are installed on both sides of the top of the base 16, and a top plate 18 is installed on the top of the two support plates 17.

[0023] As a preferred solution, further, an electric slide rail 19 is installed at the bottom of the top plate 18, a hydraulic cylinder 20 is installed at the bottom of the electric slide rail 19, a connecting block 21 is installed at the bottom of the output shaft of the hydraulic cylinder 20, a cutting motor 22 is installed on one side of the connecting block 21, and a cutting disk 23 is installed on the other side of the connecting block 21. The cutting disk 23 is connected to the output shaft of the cutting motor 22.

[0024] As a preferred solution, further, the side of the work surface 1 is provided with equidistantly arranged fixing grooves 24, and the opposite ends of the two support plates 17 are slidably installed with plug blocks 25, which cooperate with the fixing grooves 24. The plug blocks 25 are inserted into the fixing grooves 24 by sliding the plug blocks 25 to prevent the work surface 1 from rotating; anti-collision stickers 28 are installed on the opposite end sides of the two plug blocks 25, and the anti-collision stickers 28 protect the contact surface between the plug blocks 25 and the fixing grooves 24; a cutting groove 29 is provided on the top of the work surface 1, and the direction of the cutting groove 29 is the same as that of the fixing groove 24.

[0025] As a preferred solution, further, the opposite ends of the two support plates 17 are provided with sliding grooves, and the opposite ends of the two plug blocks 25 slide and extend into the sliding grooves and are threadedly installed with one end of a screw rod 26, and the other end of the screw rod 26 extends out of the support plate 17 and is installed with a knob 27. Turning the knob 27 drives the screw rod 26 to rotate, and the screw 26 drives the plug block 25 to move.

[0026] The work table, clamping plate, rotating shaft, electric slide rail, hydraulic cylinder, cutting motor, cutting disc and cutting groove in this case are existing technologies. The work table, clamping plate, rotating shaft, hydraulic cylinder, cutting motor, cutting disc and cutting groove all have the same structure and connection method as in the comparative documents. As long as the work table, clamping plate, rotating shaft, electric slide rail, hydraulic cylinder, cutting motor, cutting disc and cutting groove meet the requirements of this case, they are all acceptable.

[0027] Working principle: the electrical components appearing in the present application are all externally connected to the power supply and the control switch when in use. After the utility model is installed, first check the installation fixation and safety protection of the utility model, and then it can be used; when in use, pull the handle 13, so that the handle 13 drives the top block 12 and the operating rod 3 to move upward, and the height of the clamping plate 4 is raised. When the side groove 6 completely leaks out of the top of the fixing frame 2, the slider 7 is driven to move by pulling the pull block 8, so that the slider 7 moves out of the surface of the operating rod 3; after the sliders 7 on both sides are completely slid out of the surface of the operating rod 3, release the handle 13, and under the drive of the spring 5, the operating rod 3 moves downward, and the bottom of the slider 7 is stuck on the top surface of the fixing frame 2, so that the clamping plate 4 still stops at a certain height; the user puts the cutting piece on the top of the workbench 1, adjusts the position of the cutting piece, and pulls the handle upward again. Hand one 13, after lifting the operating rod 3 a certain distance, slides the pull block 8 and the slide block 7 into the side groove 6, so that the pull block 8 is completely pushed into the side groove 6, and then releases the handle one 13, the spring 5 drives the operating rod 3 to move downward, so that the clamping plate 4 clamps the cutting piece; then the user controls the electric slide rail 19, the hydraulic cylinder 20 and the cutting motor 22 to make the cutting disc 23 cut the cutting piece; when it is necessary to change the cutting position, the user turns the knob 27 to make the knob 27 drive the screw rod 26 to rotate, and the screw 26 drives the plug block 25 to move, so that the plug block 25 is separated from the fixed groove 24; then the user drives the work surface 1 to rotate through the handle two 14, and after rotating to the appropriate position, the user turns the knob 27 again to make the screw rod 26 drive the plug block 25 to move, and the plug block 25 enters the fixed groove 24 to fix the work surface 1, which is more practical.
