[0025] 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.

[0026] Reference Figure 1 , Figure 4 and Figure 5An embodiment of this utility model provides an indoor decorative material cutting device, comprising an outer casing 1, a motor 2 installed inside the outer casing 1, a first pulley fixedly connected to the output end of the motor 2, a second pulley rotatably connected to the first pulley via a belt, a cutting blade 3 fixedly connected to the shaft of the second pulley, a protective inner shell 4 covering the cutting blade 3, the protective inner shell 4 being fixedly connected to the outer casing 1, a protective outer shell 5 slidably connected to the outer wall of the protective inner shell 4, a handle 17 fixedly connected to the top of the outer casing 1, a connecting rod 6 fixedly connected to the top of the protective inner shell 4, an L-shaped limiting rod 7 rotatably connected to the bottom end of the arm of the connecting rod 6, a first spring 18 fixedly connected to the outer wall of the connecting rod 6, the other end of the first spring 18 being fixedly connected to the L-shaped limiting rod 7, and the shape of the end of the arm of the L-shaped limiting rod 7 facing the protective inner shell 4 fitting the outer wall of the protective inner shell 4.

[0027] Specifically, the inner protective shell 4 is fixedly connected to the outer casing 1 via a connecting block. The outer protective shell 5 has a slot at the location of the connecting block, so that the connecting block does not restrict the outer protective shell 5 from sliding to cover the cutting blade 3. The top of the slot of the outer protective shell 5 is not open. When the outer protective shell 5 slides down to cover the cutting blade 3, the connecting block will prevent the outer protective shell 5 from continuing to slide down, preventing the outer protective shell 5 from detaching from the inner protective shell 4. The outer protective shell 5 has a slot at the shaft of the pulley, so that the outer protective shell 5 will not be blocked by the shaft when sliding. The L-shaped limiting rod 7 is used to limit the position of the outer protective shell 5 when it slides. The length of the L-shaped limiting rod is greater than the length of the outer protective shell 5. When the outer protective shell 5 slides to cover the cutting blade 3, the outer protective shell 5 will be stuck between the support arm at the bottom of the L-shaped limiting rod 7 and the connecting block.

[0028] Reference Figure 2 , Figure 3 and Figure 6 A locking rod 8 is fixedly connected to the outer wall of the outer casing 1. The locking rod 8 has a locking hole. A sliding plate 10 is slidably connected to the inner wall of the guide rail 14. A slider 9 is slidably connected to the inner wall of the sliding plate 10. A locking block 11 is slidably connected to the inner wall of the slider 9. A pull rod 12 is fixedly connected to the outer wall of the locking block 11. A second spring 13 is fixedly connected to the inner wall of the slider 9. The other end of the second spring 13 is fixedly connected to the locking block 11. The other end of the locking block 11 is a slope so that the locking rod 8 can abut against the locking block 11 and slide. A threaded rod 16 is threadedly connected to the inner wall of the guide rail 14. A clamping plate 15 is rotatably connected to the outer wall of the threaded rod 16. A limit plate is fixedly connected to the lower end of the guide rail 14. The clamping plate 15 is slidably connected to the limit plate.

[0029] Specifically, the material to be cut is clamped between the clamping plate 15 and the guide rail 14. Then, by holding the handle 17, the outer cover 1 is pulled up and down on the inner wall of the slide plate 10 via the slider 11. When the outer cover 1 slides to the top, the cutting blade 3 does not contact the material to be cut. The cross-sectional area of ​​the clamping block 11 is the same as the size of the clamping hole on the clamping rod 8. The slide plate 10 slides laterally on the inner wall of the guide rail 14, while the slider 9 slides vertically in the inner wall of the slide plate 10. The slider 9 has a groove on the side facing the clamping rod 8 that allows the clamping rod 8 to slide. The contact surface between the clamping block 11 and the clamping rod 8 is only inclined, so that the clamping rod 8 is fixed on the slider 9, thereby allowing the outer cover 1 to slide up and down on the slide plate 10. Since the slide plate 10 is slidably connected to the inner wall of the guide rail 14, the outer cover 1 can also slide on the guide rail 14.

[0030] Working principle: First, when the cutting equipment is not in use, the L-shaped limiting rod 7 can be pulled to rotate it. During rotation, the first spring 18 is pulled, causing it to deform. The support arm at the bottom of the L-shaped limiting rod 7 disengages from the inner protective shell 4 and releases its restriction on the outer protective shell 5. Then, the outer protective shell 5 is slid to cover the cutting blade 3, with its top end positioned below the support arm of the L-shaped limiting rod. Then, the L-shaped limiting rod 7 is released, allowing it to reset under the elastic force of the first spring 18. The support arm at the bottom of the L-shaped limiting rod 7 re-engages with the outer wall of the inner protective shell 4, and the support arm at the bottom of the L-shaped limiting rod 7 restricts the movement of the outer protective shell 5. When the cutting equipment is needed, the L-shaped limiting rod 7 can be pulled to rotate it. During rotation, the first spring 18 will be pulled and deformed. The support arm at the bottom of the L-shaped limiting rod 7 will disengage from the inner protective shell 4 and release the restriction on the outer protective shell 5. Then, the outer protective shell 5 will be slid upward until the cutting blade 3 is exposed and the bottom of the outer protective shell 5 is above the support arm of the L-shaped limiting rod 7. Then, the L-shaped limiting rod 7 will be released and reset under the elastic force of the first spring 18. The support arm at the bottom of the L-shaped limiting rod 7 will re-contact the outer wall of the inner protective shell 4, and the support arm at the bottom of the L-shaped limiting rod 7 will restrict the outer protective shell 5 from sliding downward.

[0031] When cutting wider materials or when precise cutting is required, the handle 17 can be pushed, which in turn drives the outer casing 1 to push the locking rod 8. The locking rod 8 then abuts against the locking block 11, pushing the locking block 11 back into the inner wall of the slider 9. As the locking block 11 retracts, it compresses the second spring 13, causing it to deform. When the locking rod 8 continues forward until its locking hole is parallel to the locking block 11, the locking block 11, no longer abutted, will spring back into the locking hole of the locking rod 8 under the elastic force of the second spring 13, thus fixing the locking rod 8 onto the slider 9. This allows the outer casing 1 to... The slide plate 10 slides up and down. Since the slide plate 10 is slidably connected to the inner wall of the guide rail 14, the outer cover 1 of the machine can also slide on the guide rail 14. Then, the material to be cut is placed between the guide rail 14 and the clamping plate 15. Then, the threaded rod 16 is rotated to shorten the distance between the clamping plate 15 and the guide rail 14, clamping the material between the clamping plate 15 and the guide rail 14. Then, the motor 2 is started. The motor 2 drives the cutting blade 3 to rotate through the pulley and belt, thereby cutting the material. Since the outer cover 1 of the machine can slide in a straight line on the guide rail 14, it can prevent positional displacement during cutting.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
