The spring slides through the sliding rod, with its upper end fixedly connected to the pressing cutter head and its lower end fixedly connected to the sliding seat. A blade outlet groove is formed at the bottom of the front groove of the sliding seat. Buckle protrusions are fixedly connected to both sides of the sliding seat that slide in contact with the ruler rail, and a telescopic groove is formed in the middle of one side. The buckle protrusions slide and engage in the groove. A locking element is installed in the telescopic groove, located on one side of the sliding seat. The sliding seat moves on the ruler rail. By checking the scale line at the corresponding groove, the position of the sliding seat can be determined. The locking device locks the sliding seat in place at the corresponding position on the ruler rail.

[0005] In a preferred embodiment of this invention, an indicator light module is provided at the end of the ruler rail. The indicator light in the module is located on the upper surface of the ruler rail. The indicator light module includes a first press switch and a second press switch, which are respectively located at the two ends of the top inner side of the hook. The first and second press switches are connected in series, and the indicator light will only illuminate when both are pressed simultaneously. When the top inner surface of the hook is completely in contact with the edge of the board, the first and second press switches are pressed simultaneously, and the indicator light illuminates. At this time, the ruler rail is perpendicular to the edge of the board. When the ruler rail is tilted relative to the edge of the board or detached from the edge, one end of the top inner surface of the hook will tilt up and not contact the edge of the board, or neither end will contact the edge of the board. In this case, at least one of the first and second press switches will not be pressed and the indicator light will not illuminate. Therefore, by observing whether the indicator light is illuminated, it can be determined whether the hook is in contact with the edge of the board, thereby ensuring that the distance from the cutting position to the edge of the board remains unchanged during the cutting process by the moving ruler rail pressing the cutting head, ensuring the accuracy of the cutting dimensions.

[0006] In a preferred embodiment of this utility model, the pressing and cutting head is equipped with a secondary start switch at its top and sliding insertion holes at both ends of its lower part. These sliding insertion holes correspond one-to-one with the sliding rods. A motor is installed in the lower center of the pressing and cutting head, and a drive gear is fixedly connected to the motor's shaft. A cutting blade assembly is meshed with the drive gear and rotatably mounted on the pressing and cutting head. The battery, main start switch, secondary start switch, and motor are electrically connected. The motor can only be started when both the main start switch and the secondary start switch are turned on simultaneously; the motor will not start if only one switch is turned on, thus ensuring safety during use.

[0007] As a preferred embodiment of this utility model, the cutting blade assembly includes a driven gear, and a blade is coaxially fixedly connected to the driven gear. The driven gear is meshed with the driving gear. The blade is located at the blade outlet and is flush with the side wall of the corresponding groove. The zero mark of the scale line is flush with the inner top surface of the hook. When the hook is hooked on the edge of the board, the inner top surface of the hook is in contact with the edge of the board. The sliding seat is moved, and the scale corresponding to the side wall of the corresponding groove is the distance from the blade to the edge of the board, that is, the width of the cut board.

[0008] In a preferred embodiment of this invention, the locking component includes a screw rod that is rotatably latched onto the sliding seat. A handwheel is fixedly connected to the outer end of the screw rod, and a pressing block is threadedly connected to the inner end. The pressing block is slidably fitted into the telescopic groove. Rotating the screw rod with the handwheel causes the pressing block to move within the telescopic groove. The pressing block extends out of the groove and presses against the ruler rail, locking the sliding seat. When the pressing block retracts into the groove, it disengages from the ruler rail, allowing the sliding seat to slide freely on the rail.

[0009] The beneficial effects of this utility model are as follows: This utility model designs a ruler rail with graduated lines, on which a sliding seat and a pressing cutter head are slidably mounted. The cutting position of the pressing cutter head can be adjusted by sliding the sliding seat on the ruler rail. In the non-working state, the pressing cutter head retracts into the sliding seat, thus avoiding the danger of the blade being exposed. When cutting is needed, pressing the pressing cutter head downwards allows the blade to extend from the bottom of the sliding seat for cutting. The cutting is driven by a motor, resulting in better cutting effect and higher efficiency, effectively improving work efficiency. The hook design on the ruler rail, combined with two indicator lights with push-button switches, allows the ruler rail to move along the edge of the material during cutting. The indicator lights indicate the contact status between the hook and the material, ensuring the stability of the ruler rail movement and ensuring accurate cutting dimensions.

[0016] Example 1

[0017] like Figures 1 to 5As shown, this utility model discloses a board cutting device. A handle 2 is fixedly connected to one end of a ruler rail 1, and a hook 101 is fixedly connected to the lower end of the handle. An indicator light module is provided at the end of the ruler rail 1. The indicator light 107 in the indicator light module is located on the upper surface of the ruler rail 1. The indicator light module is provided with a first press switch 105 and a second press switch 106. The first press switch 105 and the second press switch 106 are respectively located at the two ends of the top inner side of the hook 101. The first press switch 105 and the second press switch 106 are connected in series. The indicator light 107 will only light up when they are pressed simultaneously. When the top inner side of the hook 101 is completely in contact with the edge of the board, the first press switch 105 and the second press switch 106 are pressed simultaneously, and the indicator light 107 lights up. At this time, the ruler rail 1 is perpendicular to the edge of the board. When the ruler rail 1 is tilted relative to the edge of the board or detached from the edge of the board, one end of the inner top surface of the hook 101 will tilt up and not contact the edge of the board, or neither end will contact the edge of the board. At this time, at least one of the first press switch 105 and the second press switch 106 will not be pressed and turned on, and the indicator light 107 will not light up. Therefore, by observing whether the indicator light 107 is lit, it can be determined whether the hook 101 is in contact with the edge of the board. The ruler rail 1 has sliding grooves 102 on both sides, scale lines 103 on the upper surface, and rollers 104 are rotatably embedded at equal intervals on the lower surface. By gripping and pushing the ruler rail 1 with the handle 2, the rollers 104 roll on the surface of the board, thereby facilitating the movement of the ruler rail 1 on the surface of the board.

[0018] A sliding seat 3 is mounted on the ruler rail 1 via a sliding buckle. A battery 309 is housed inside the sliding seat 3. A main start switch 301 and a charging port 302 are located on the side. The charging port 302 is electrically connected to the battery 309 for charging. A scale-corresponding groove 303 is formed on the upper front edge of the sliding seat 3, corresponding to the scale line 103. A sliding rod 304 is fixedly connected to the bottom of the front groove of the sliding seat 3. A pressing and cutting head 4 is slidably mounted on the sliding rod 304. A spring 305 is pressed between the lower part of the pressing cutting head 4 and the bottom of the front groove of the sliding seat 3. The spring 305 is slidably connected to the slide rod 304, and its upper end is fixedly connected to the pressing cutting head 4, and its lower end is fixedly connected to the sliding seat 3. The bottom of the front groove of the sliding seat 3 is provided with a blade outlet groove 306. The two sides of the sliding seat 3 that slide in contact with the ruler rail 1 are fixedly connected with a buckling boss 307, and a telescopic groove 308 is provided in the middle of one side. The buckling boss 307 is slidably buckled in the slide groove 102.

[0019] A locking element 5 is installed in the telescopic slot 308. The locking element 5 includes a screw 501 that is rotated and latched onto the sliding seat 3. A handwheel 502 is fixedly connected to the outer end of the screw 501, and a pressing block 503 is threadedly connected to the inner end. The pressing block 503 is slidably installed in the telescopic slot 308. By rotating the screw 501 with the handwheel 502, the screw 501 drives the pressing block 503 to move in the telescopic slot 308. The pressing block 503 extends out of the telescopic slot 308 and presses against the ruler rail 1, thereby locking the sliding seat 3. The pressing block 503 retracts into the telescopic slot 308, disengaging from the ruler rail 1, allowing the sliding seat 3 to slide freely on the ruler rail 1. As the sliding seat 3 moves on the ruler rail 1, the position of the sliding seat 3 is determined by observing the scale line 103 at the corresponding slot 303. The locking element 5 then locks and fixes the sliding seat 3 to the corresponding position on the ruler rail 1.

[0020] The pressing and cutting head 4 has a secondary start switch 401 at its top and sliding insertion holes 402 at both ends of its lower part. These sliding insertion holes 402 are inserted into the sliding rods 304 one-to-one. A motor 403 is installed in the lower center of the pressing and cutting head 4. A drive gear 404 is fixedly connected to the shaft of the motor 403. A cutting blade assembly 405 is meshed with the drive gear 404 and rotatably mounted on the pressing and cutting head 4. The cutting blade assembly 405 includes a driven gear 4051, which is coaxially fixed. A blade 4052 is fixedly connected. The driven gear 4051 meshes with the driving gear 404. The blade 4052 is located at the blade slot 306 and is flush with the side wall of the scale corresponding slot 303. The zero mark of the scale line 103 is flush with the inner top surface of the hook 101. When the hook 101 is hooked on the edge of the board, so that the inner top surface of the hook 101 is in contact with the edge of the board, the sliding seat 3 is moved. The scale corresponding to the side wall of the scale corresponding slot 303 is the distance from the blade 4052 to the edge of the board, that is, the width of the cut board. The battery 309, the main start switch 301, the auxiliary start switch 401 and the motor 403 are electrically connected. The motor 403 can only be started when both the main start switch 301 and the auxiliary start switch 401 are turned on. The motor 403 will not start when only one switch is turned on, thus ensuring safety during use.

[0021] When cutting the board, adjust the position of the sliding seat 3 according to the required width of the board to be cut, so that the scale groove 303 corresponds to the corresponding scale on the scale line 103. Lock the sliding seat 3 with the locking piece 5, then hook the hook 101 onto the edge of the board. Hold the handle 2 with one hand and the pressing cutter head 4 with the other hand. Turn on the main start switch 301. When the indicator light 107 is lit, press the pressing cutter head 4 down to push the blade 4052 out from the blade slot 306 so that it contacts the board. At the same time, press the auxiliary start switch 401 to start the motor 403. The motor 403 drives the blade 4052 to rotate through the drive gear 404 and the driven gear 4051 to cut the board. Simultaneously, push the ruler 1 to make the entire device move in a straight line along the edge of the board to complete the cutting of the entire board. During the process, constantly observe the indicator light 107. If it goes out, stop moving the ruler rail 1 and adjust the hook 101 to be in close contact with the edge of the board, keeping the indicator light 107 lit. This ensures that the distance from the cutting position to the edge of the board remains unchanged during the cutting process by moving the ruler rail 1 and pressing the cutting head 4, thus ensuring the accuracy of the cutting dimensions.
