The other end of the tension spring 404 is connected to the sliding portion; the elastic portion is located in the connection hole; when the sliding portion moves to the bottom of the plug-in portion, the tension spring 404 is stretched, and the elastic portion is deformed and extends out from the inside of the connection hole; the inflation unit is connected to the control strip 401 and is used to inflate the first airway 4011.

[0023] The opening directions of the first receiving groove and the second receiving groove may be the same and parallel to the horizontal direction.

[0024] Installation and replacement process of bakelite 200: Stack a plurality of bakelite boards 200 together and make the stacking direction intersect perpendicularly with the axial direction of the mounting hole 201, then put the bakelite boards 200 into the second receiving groove from the opening of the second receiving groove, press the bakelite boards 200 along the stacking direction of the bakelite boards 200, so that the bakelite boards 200 close to the moving knife mechanism fit with the moving knife mechanism; press the control strip 401 along the direction of the mounting hole 201, so that the fixing rod 402 is inserted into the mounting hole 201, the compression spring 403 is compressed, and finally the fixing rod 402 passes through the mounting hole 201 and the plug-in portion is inserted into the locking groove 1022, at this time continue to press the control strip 401, and use the inflation unit to inflate the first air passage 4011. Gas, the gas enters the mounting hole 201 through the first gas channel 4011, the second gas channel 4021 and the air outlet 4022. At this time, both ends of the mounting hole 201 are sealed by the fixed rod 402; the gas in the second gas channel 4021 compresses the sliding part to move toward the plug-in part, the tension spring 404 is stretched, and the sliding part drives the elastic part to deform and extend out of the connecting hole. The size of the elastic part in the radial direction of the mounting hole 201 is larger than the size of the slot of the locking groove 1022, so that the card-connecting unit is carded in the locking groove 1022. At this time, the control strip 401 can be loosened, but the control strip 401 will continue to compress the compression spring 403, and the fixed rod 402 will not detach from the mounting hole 201. When the bakelite board 200 near the moving knife mechanism is worn to the point that the side wall of the mounting hole 201 is cracked, the gas is released. At this time, the air pressure in the first air channel 4011 and the second air channel 4021 decreases, the air pressure on the sliding part disappears, the tension spring 404 returns to its original state and drives the sliding part to move away from the plug-in part, the elastic part returns to its original state and is retracted into the connecting hole, the plug-in part can be detached from the locking groove 1022, the compression spring 403 returns to its original state and drives the control strip 401 to move to the side away from the locking groove 1022, so that the fixing rod 402 is detached from the mounting hole 201, and the operator observes that the control strip 401 is bounced away From the side away from the bakelite board 200, it can be known that the bakelite board 200 is worn. At this time, the worn bakelite board 200 can be taken out from the opening of the second accommodating groove, and then the unused bakelite board 200 can be pushed toward the moving knife mechanism, and the control strip 401 is pressed again to move toward the locking groove 1022, so that the fixing rod 402 is inserted into the mounting hole 201 of the new bakelite board 200 and the plug-in part is inserted into the locking groove 1022. At this time, the inflation unit is used to inflate the first air duct 4011 and the second air duct 4021, and the snap-on unit can be re-snaked into the locking groove 1022, thereby completing the fixation of the new bakelite board 200.

[0025] When pressing the control strip 401, the control strip 401 can be manually or with a tool moved from the opening of the first receiving groove; or a through hole connected to the first receiving groove can be provided on the fuselage assembly 100, and a tool can be passed through the through hole and abutted against the control strip 401 to move toward the mounting hole 201. Similarly, when pushing the bakelite board 200, the bakelite board 200 can be manually or with a tool moved from the opening of the second receiving groove; or a through hole connected to the second receiving groove can be provided on the fuselage assembly 100, and a tool can be passed through the through hole and abutted against the bakelite board 200 to move toward the movable knife mechanism.

[0026] In one embodiment, the number of the mounting holes 201 on the bakelite board 200 may be two, and the number of the fixing rods 402 may also be two.

[0027] In one embodiment, the sliding portion includes a top block 405 and a limit member 406 that are connected to each other; the cross-sectional area of ​​the limit member 406 is larger than the cross-sectional area of ​​the top block 405; the fixed rod 402 is provided with a limit groove that cooperates with the limit member 406; one end of the tension spring 404 is connected to the bottom of the limit groove, and the other end of the tension spring 404 is connected to the limit member 406; the top block 405 is sealed and cooperated with the second air duct 4021, and the end of the top block 405 away from the tension spring 404 is transmission-connected to the elastic portion.

[0028] Both the top block 405 and the stopper 406 can be cylindrical, wherein the stopper 406 can be plate-shaped. The distance between the end surface of the top block 405 close to the control strip 401 and the stopper 406 is a, and the maximum distance between the stopper 406 and the bottom of the stopper groove is b, a>b, so that the top block 405 has a sealing effect on the second air channel 4021, preventing gas from entering the stopper groove, causing the tension spring 404 to rust after long-term use.

[0029] In one embodiment, the elastic part includes an elastic member (not shown in the figure) and two locking blocks 407; the number of connecting holes is two and they are respectively located on both sides of the extension direction of the second air channel 4021; the two locking blocks 407 are respectively matched with one connecting hole; the two ends of the elastic member are respectively connected to one locking block 407; the end of the top block 405 away from the tension spring 404 is conical or V-shaped. The elastic member can be, but is not limited to, a rubber body, a spring and other structures.

[0030] When the second air channel 4021 is not filled with gas, the tension spring 404 is not deformed, and the end of the top block 405 close to the locking block 407 does not move to the position corresponding to the connection hole; as the gas enters the second air channel 4021, the air pressure in the second air channel 4021 gradually increases, and the air pressure presses the top block 405 to move toward the locking groove 1022, and the tension spring 404 is gradually stretched. The end of the top block 405 away from the tension spring 404 is inserted into the gap between the two locking blocks 407, and the locking block 407 slides along the connection hole and finally extends out of the connection hole, and the elastic member between the two locking blocks 407 is stretched. At this time, the maximum distance between the outer diameters of the two locking blocks 407 is greater than the aperture of the notch of the locking groove 1022, so that the locking block 407 can be clamped in the locking groove 1022.

[0031] When the gas in the second air channel 4021 gradually disappears, the tension spring 404 drives the top block 405 away from the locking groove 1022, and the end of the top block 405 close to the locking block 407 is away from the position of the connecting hole corresponding to the second air channel 4021. At this time, the elastic member between the two locking blocks 407 returns to its original state, and the two ends of the elastic member move toward the middle, so that the locking block 407 moves along the connecting hole toward the center of the second air channel 4021. When the two locking blocks 407 all enter the connecting hole, the plug-in part disengages from the locking groove 1022, and the compression spring 403 begins to return to its original state. The compression spring 403 drives the control strip 401 to move away from the locking groove 1022, and finally the fixing rod 402 disengages from the mounting hole 201. At this time, the worn bakelite board 200 can be replaced.

[0032] One end of the top block 405 away from the tension spring 404 is conical or V-shaped, so that the top block 405 can be inserted between the two locking blocks 407 relatively smoothly.

[0033] In one embodiment, the locking block 407 is provided with an inclined surface for matching the top block 405. When the end of the top block 405 away from the tension spring 404 is conical, the inclined surface of the locking block 407 is semi-conical, and after the two locking blocks 407 are brought together, the two semi-cones are combined into a cone to match the top block 405. When the end of the top block 405 away from the tension spring 404 is a V-shaped block, the inclined surface of the locking block 407 is an inclined surface, and after the two locking blocks 407 are brought together, the two inclined surfaces are combined into a V-shaped groove. The locking block 407 is provided to match the inclined surface of the top block 405, so that the top block 405 can slide along the inclined surface to between the two top blocks 405.

[0034] In one embodiment, the inflation unit includes an inflation pump 408 and an inflation hose 409; the inflation pump 408 is disposed on the fuselage assembly 100 and is located outside the first receiving groove; one end of the inflation hose 409 is connected to the inflation pump 408, and the other end is connected to the first air duct 4011.

[0035] The air pump 408 is fixed on the fuselage assembly 100, and a certain length of the air hose 409 needs to be reserved to prevent the air hose 409 from being straightened when the control strip 401 moves to the side wall of the first accommodating groove away from the mounting hole 201, causing the fixing rod 402 to be partially located in the mounting hole 201, affecting the removal of the worn bakelite board 200.

[0036] In one embodiment, the control strip 401 is provided with a block 4012 , and the side wall of the first receiving groove is provided with a sliding groove 1021 that cooperates with the block 4012 .

[0037] The cooperation between the block 4012 and the slide groove 1021 has a positioning effect on the control strip 401 and the fixing rod 402, so that when the bakelite board 200 abuts against the movable knife mechanism and the bottom of the second receiving groove, the fixing rod 402 can be aligned with the mounting hole 201 of the bakelite board 200. In addition, the cooperation between the block 4012 and the slide groove 1021 can prevent the control strip 401 from tilting when sliding along the side wall of the first receiving groove.

[0038] When installing the bakelite board 200, multiple bakelite boards 200 can be placed into the slot of the second receiving slot so that the bakelite board 200 abuts against the bottom of the second receiving slot and the moving knife mechanism to achieve the positioning of the bakelite board 200, so that the installation hole 201 of the bakelite board 200 can be aligned with the fixing rod 402 more smoothly.

[0040] When the fixing rod 402 is inserted into the mounting hole 201 of the bakelite board 200, the knob 410 is rotated forward, and the knob 410 presses the control strip 401 to prevent the control strip 401 from jumping under the action of the compression spring 403. After the clamping unit is clamped with the locking groove 1022, the knob 410 is rotated in the reverse direction to make the knob 410 disengage from the first receiving groove, so as to prevent the bakelite board 200 from being worn to the side wall of the mounting hole 201 being cracked, and the compression spring 403 drives the control strip 401 to jump to the side away from the locking groove 1022 and be interfered by the knob 410.

[0041] In one embodiment, the locking assembly 400 further includes a rotating wheel 411, a screw rod 413 and a push plate 412; the body assembly 100 is provided with a threaded hole matched with the screw rod 413; the extension direction of the screw rod 413 is perpendicular to the extension direction of the mounting hole 201; one end of the screw rod 413 is connected to the rotating wheel 411, and the other end of the screw rod 413 passes through the body assembly 100 and is rotatably connected to the push plate 412; the push plate 412 abuts against the bakelite board 200. When the worn bakelite board 200 is taken out of the second receiving groove, the rotating wheel 411 is rotated, and the screw rod 413 moves axially to drive the push plate 412 to squeeze the bakelite board 200 to abut against the moving knife mechanism, and the operation is simple and quick.

[0042] In one embodiment, the body assembly 100 includes a body 101 and a cover body 102; the movable knife mechanism is slidably disposed on the body 101; and the cover body 102 is provided with a first receiving groove and a second receiving groove.

[0043] When replacing the wood plywood, the cover body 102 may not be detached from the machine body 101 , thereby increasing the convenience of replacing the plywood board 200 .

[0047] The raw material to be processed is placed in the processing groove, and the movable blade body 302 moves toward the fixed blade body 301. The movable blade body 302 and the fixed blade body 301 clamp and cut the raw material to complete the cutting operation.

[0048] refer to Figure 3When the movable knife body 302 cuts harder raw materials for production, the deflection force on the slider 303 is more serious. Let the deflection force be F1. At this time, the friction between the slider 303 and the bakelite board 200 is relatively large, and the bakelite board 200 will generate heat. At this time, the gas in the mounting hole 201 expands due to the heat, and the bakelite board 200 will generate pressure F2 on the slider 303. The torques generated by F1 and F2 at point O can offset each other to some extent, thereby alleviating the unbalanced force on the slider 303.

[0049] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
