[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] A type of cut-resistant table saw, such as Figures 1-3 As shown, the machine includes a frame 1, guide rails 2, a movable carrier plate 3, and a cutting assembly 4. The cutting assembly 4 is fixed to the frame 1. Two guide rails 2 are provided, arranged parallel to each other on the frame 1. The movable carrier plate 3 is slidably mounted on the guide rails 2, guiding the movable carrier plate 4 to move horizontally. In use, the wood is fixed to the movable carrier plate 3, and the operator only needs to push the movable carrier plate 3 to push the wood towards the cutting assembly 4. During this process, hands should be kept away from the cutting assembly 4, thus effectively preventing accidents.

[0022] The movable carrier plate 3 includes a plate body 31, an adjusting plate 32, a top plate 33, a guide rod 34, a first spring 35, and a locking mechanism 36. A reference portion 311 protrudes from the upper surface of the plate body 31. The adjusting plate 32 is slidably mounted on the plate body 31. The top plate is parallel to the reference portion 311. The top plate 33 is slidably mounted on the adjusting plate 32 via the guide rod and the first spring 35. The locking mechanism 36 is mounted on the adjusting plate 32 and fixes the adjusting plate 32 to the plate body 31. By horizontally moving the adjusting plate 32, the distance between the adjusting plate 32 and the reference portion 311 can be adjusted, thus adapting to plates of different sizes. Furthermore, the floating top plate 33 presses the plate firmly against the reference plate, thus fixing the plate horizontally.

[0023] In one embodiment, such as Figures 1-3 As shown, the adjusting plate 32 is provided with at least two guide holes, the guide rod 34 is slidably connected to the guide holes, one end of the guide rod 34 is connected to the top plate 33, the first spring 35 is provided on the guide rod 34, and the two ends of the first spring 35 act on the adjusting plate 32 and the top plate 33.

[0024] In the above embodiments, such as Figures 1-3 As shown, a radial and through hole is provided on the guide rod 34, and a limiting pin is inserted into the through hole. The limiting pin restricts the ejection position of the top plate 33, which facilitates the installation of the guide rod 34 and prevents the guide rod 34 from separating from the adjusting plate 32.

[0025] In one embodiment, such as Figures 1-3 As shown, a groove 312 is recessed on the plate body 31, and the adjusting plate 32 is slidably connected to the groove 312. Preferably, the groove 312 is a dovetail groove.

[0026] In one embodiment, such as Figures 1-3As shown, the locking mechanism 36 includes a locking seat 361, a locking plate 362, a second spring 363, and a limiting pin 364. The locking seat 361 has a guide groove, and the locking plate 362 is slidably connected to the guide groove. The second spring 363 connects the locking plate 362 and the locking seat 361. The limiting pin 364 is disposed on the locking plate 362, limiting the locking position of the locking plate 362. Locking grooves 313 that cooperate with the locking plate 362 are provided at intervals on the plate body 31. Preferably, two second springs 363 are provided, respectively disposed on both sides of the locking plate 362, to ensure uniform force distribution on both sides of the locking plate 362.

[0027] In one embodiment, such as Figures 1-3 As shown, the side of the top plate 33 closest to the reference part is a slope.

[0028] In one embodiment, such as Figures 1-3 As shown, at least one clamping component 5 is provided at intervals above the board body 31. The clamping component 5 applies downward pressure to the board to ensure that the board is stably fixed on the board body 31 and to prevent the board from shaking during cutting.

[0029] In one embodiment, such as Figures 1-3 As shown, the clamping assembly 5 includes a lever cylinder 51, a pressure rod 52, a pressure pad 53, and a nut 54. The lever cylinder 51 has a through-hole threaded hole. The pressure rod 52 is threaded into the screw hole. The nut 54 is mounted on the pressure rod 52, and the pressure pad 53 is located at the lower end of the pressure rod 52. The pressure rod 52 engages with the screw hole to adjust the axial position of the pressure pad 53 to accommodate plates of different thicknesses. The nut 54 is used to lock the pressure rod 52, preventing loosening during use.

[0030] In the above embodiments, such as Figures 1-3 As shown, two nuts 54 are provided.

[0031] In one embodiment, a protective cover 6 is also provided on the frame 1, and the protective cover 6 is located above the cutting assembly 4. Because the size of the protective cover 6 covers the cutting blade of the cutting assembly 4, it will have a certain obstruction and warning effect on the workers, further preventing accidents from occurring.

[0032] When using this utility model, such as Figures 1-3As shown, the locking plate 362 of the locking mechanism 36 is pulled up to separate it from the locking groove 313. The adjusting plate 32 is moved to adjust the distance between the adjusting plate 32 and the reference part 311 to adapt to different sizes of plates. The plate loading step is as follows: one side of the plate is pressed against the top plate 33, and the top plate 33 is pushed to move. The first spring 35 is compressed, and the gap between the top plate 33 and the reference part 311 is greater than the width of the plate. Then the plate is placed on the moving carrier plate 3. After release, the top plate 33 is pressed against the reference part 311 by the restoring force of the first spring 35. In addition, the horizontal position of the plate needs to be adjusted, and its length protruding from the moving carrier plate 3 needs to be adjusted. After the adjustment is completed, the pressing component 5 is controlled to press the plate onto the moving carrier plate 3. The worker pushes the moving carrier plate 3 to move the plate toward the cutting component 4, thereby realizing the cutting of the plate. The cutting component 4 is a conventional structure and will not be described in detail here.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
