A fixed block is fixedly connected to one side of the movable rod. A return spring is movably connected to one side of the movable rod.

[0004] The aforementioned device uses a return spring and a movable rod to position the cutting blade. During operation, once the movable rod is released, the cutting blade can move freely, allowing the user to adjust the cutting spacing. While this adjustment method is convenient, it has a drawback: when moving the cutting blade to adjust the spacing, it cannot be guaranteed that the interval between each cutting blade will be completely consistent. This inconsistency may negatively impact cutting accuracy, thereby affecting the quality of the final product. Utility Model Content

[0010] Preferably, the adjusting mechanism includes a positioning sleeve and an adjusting rod fixedly mounted on the movable slider, with the adjusting rod slidably mounted inside the positioning sleeve. The adjusting rod has a toothed groove, and a gear is rotatably mounted on one side of the toothed groove, meshing with the toothed groove. A square tube is provided above the gear, and a locking sleeve is slidably mounted on the square tube. A spring seat is fixedly mounted on the locking sleeve, and a tension spring is fitted on the locking sleeve.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a saw width adjustment mechanism for a sawing machine, including a drive shaft 1, an adjustment groove 2 on the top of the drive shaft 1, movable grooves 3 on both sides of the drive shaft 1, a cutting mechanism 4 installed on the drive shaft 1, and an adjustment mechanism 5 inside the drive shaft 1. By cooperating with the cutting mechanism 4 and the adjustment mechanism 5, the distance between the saw blades 405 can be precisely adjusted to ensure cutting accuracy.

[0024] like Figure 2 and Figure 3As shown, the cutting mechanism 4 includes a sliding sleeve 403 slidably mounted on the drive shaft 1, a fixed sleeve 404 fixedly mounted on the sliding sleeve 403, a saw blade 405 fixedly mounted on the fixed sleeve 404, a connecting hole 407 opened on the fixed sleeve 404, and a bolt 406 installed in the connecting hole 407. The cutting mechanism 4 also includes a movable slider 401 slidably mounted in the drive shaft 1, a connecting leg 402 fixedly mounted on the movable slider 401, and the end of the connecting leg 402 fixedly mounted on the sliding sleeve 403. A screw hole is opened on the sliding sleeve 403, and the bolt 406 is connected to the sliding sleeve 403 through the screw hole.

[0025] Specifically, during use, the fixing sleeve 404 is first fitted onto the sliding sleeve 403, and then the saw blade 405 is quickly fixed onto the sliding sleeve 403 by tightening the bolt 406. Once the saw blade 405 is fixed onto the sliding sleeve 403, the distance between the saw blades 405 can be adjusted by moving the sliding sleeve 403, thus facilitating the cutting of plates of different widths. Furthermore, when it is necessary to replace the saw blade 405, simply loosen the bolt 406 to quickly remove the damaged saw blade 405, making the replacement of the saw blade 405 convenient and quick.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the adjustment mechanism 5 includes a positioning sleeve 501 and an adjusting rod 502 fixedly mounted on the movable slider 401. The adjusting rod 502 is slidably mounted inside the positioning sleeve 501. A toothed groove 508 is provided on the adjusting rod 502. A gear 509 is rotatably mounted on one side of the toothed groove 508 and meshes with the toothed groove 508. A square tube 504 is provided above the gear 509. A locking sleeve 505 is slidably mounted on the square tube 504. A spring seat 506 is fixedly mounted on the locking sleeve 505. A tension spring 507 is sleeved on the locking sleeve 505. A knob 503 is fixedly mounted on the upper end of the square tube 504. A locking pin 510 is fixedly mounted on the lower end of the locking sleeve 505. A movable shaft is fixedly mounted on the gear 509. The gear 509 is rotatably mounted inside the positioning sleeve 501 through the movable shaft, and the lower end of the square tube 504 is fixedly mounted on the movable shaft of the gear 509.

[0027] Specifically, during the adjustment operation, the locking sleeve 505 must first be pulled upwards. This action releases the locking pin 510, allowing it to disengage from its original slot position. Once the locking pin 510 successfully disengages, the next step is to rotate the square tube 504. The rotation of the square tube 504 directly causes the gear 509 to rotate. Once the gear 509 begins to rotate, it will cause the adjusting rod 502 to extend and retract through mechanical linkage. The extension and retraction of the adjusting rod 502 will further drive the movable slider 401 to move back and forth. Through the back and forth movement of the movable slider 401, the saw blade 405 can be adjusted to the desired position, thereby changing the distance between the saw blades 405. Furthermore, by precisely controlling the number of rotations of the square tube 504, the displacement of the saw blade 405 can be precisely controlled. This precise adjustment mechanism ensures that the distance between the saw blades 405 can be accurately set, thus guaranteeing the accuracy and quality of the cutting operation.

[0028] Working principle: When in use, the fixing sleeve 404 can be placed on the sliding sleeve 403, and then the bolt 406 can be tightened to quickly fix the saw blade 405 on the sliding sleeve 403. After the saw blade 405 is fixed on the sliding sleeve 403, the sliding sleeve 403 can be moved to adjust the distance between the saw blades 405, which is convenient for cutting boards of different widths. After loosening the bolt 406, the damaged saw blade 405 can be quickly removed for easy replacement. During adjustment, first pull the locking sleeve 505 upwards to disengage the locking pin 510 from the slot. After the locking pin 510 disengages from the slot, the square tube 504 can be rotated. Rotating the square tube 504 will drive the gear 509 to rotate. After the gear 509 rotates, it will drive the adjusting rod 502 to extend and retract. When the adjusting rod 502 extends and retracts, it will drive the movable slider 401 to move back and forth. After the movable slider 401 moves back and forth, it will drive the saw blade 405 to move back and forth, thereby adjusting the distance between the saw blades 405. By controlling the number of rotations of the square tube 504, the displacement of the saw blade 405 can be precisely controlled, thereby accurately adjusting the distance between the saw blades 405 and ensuring cutting accuracy.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
