[0014] Technical effects and advantages of the utility model:
[0015] 1. In the actual operation of the present invention, when the saw blade cuts the material, the two clamping blocks will drop vertically due to their own gravity and fit against the sides of the saw blade. At the same time, the protruding brushes in the two clamping blocks will press the two sides of the saw blade, thereby improving the stability of the saw blade during cutting and the safety of use, avoiding the bending of the saw blade and the problem of the saw blade cutting people. At the same time, when the saw blade is gradually embedded in the material, the upper surface of the material will push the two clamping blocks to move upward. Due to the vertical connection of the sliding rod, the clamping blocks will slide in the corresponding connecting plate through the sliding rod, thereby avoiding the clamping blocks affecting the cutting of the saw blade.
[0016] 2. When the cutting is completed, when the personnel take out the bow frame and the saw blade, the two clamping blocks will automatically drop by their own gravity, and the protruding brushes of the two clamping blocks will drop to the position of the saw teeth. Since the thickness of the saw teeth is less than the thickness of the saw blade, the protruding brushes will continue to extend and fit the side of the cut saw teeth to push out the debris between the saw teeth and play a cleaning role.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides Figure 1-Figure 4 The forward saw shown in the figure can prevent scratches on the human body, including a bow frame 1, fixed ends 3 are arranged on both sides of the bottom end of the bow frame 1, a saw blade 4 is arranged between the two fixed ends 3, saw teeth 11 are fixed to the bottom end of the saw blade 4, an auxiliary handle 2 is fixed on one side of the bow frame 1, and anti-slip grooves are arranged on the outer side of the auxiliary handle 2.
[0024] In actual operation of the utility model, the user can grab the bow frame 1 through the auxiliary handle 2, and saw the wood or other materials through the saw blade 4 and the saw teeth 11. The anti-slip pattern can prevent the user from slipping when grabbing the auxiliary handle 2.
[0025] Connecting plates 8 are fixed on both sides of the middle of the bow frame 1, and clamping blocks 5 are fitted on both sides of the saw blade 4 along the length direction. A fixing plate 6 is fixed in the middle of the two clamping blocks 5 away from each other on the side, and the two fixing plates 6 correspond to the positions of the connecting plates 8 respectively. Sliding rods 7 are fixed to the top of the two fixing plates 6, and the tops of the two sliding rods 7 extend out of the corresponding connecting plates 8, and blocking blocks 9 are fixed to the tops of the extended ends of the sliding rods 7. Grooves 12 are provided on the opposite sides of the two clamping blocks 5, and protruding brushes 10 are telescopically provided inside the two grooves 12. The two grooves 12 are opened along the length direction of the corresponding clamping blocks 5, and the two clamping blocks 5 are distributed along the length direction of the saw blade 4. Sliding holes for the corresponding sliding rods 7 to pass through are opened on the tops of the two connecting plates 8, and the lengths of the two sliding rods 7 are consistent.
[0026] In the actual operation of the utility model, when the saw blade 4 cuts the material, the two clamping blocks 5 will drop vertically due to their own gravity and fit against the sides of the saw blade 4. At the same time, the protruding brushes 10 in the two clamping blocks 5 will press the two sides of the saw blade 4 to improve the stability of the saw blade 4 when cutting. At the same time, when the saw blade 4 is gradually embedded in the material, the upper surface of the material will push the two clamping blocks 5 to move upward. Due to the vertical connection of the sliding rod 7, the clamping blocks 5 will slide in the corresponding connecting plate 8 through the sliding rod 7 to prevent the clamping blocks 5 from affecting the cutting of the saw blade 4.
[0027] When the cutting is completed, when the personnel take out the bow frame 1 and the saw blade 4, the two clamping blocks 5 will automatically descend due to their own gravity, and the protruding brushes 10 of the two clamping blocks 5 will descend to the position of the saw teeth 11. Since the thickness of the saw teeth 11 is less than the thickness of the saw blade 4, the protruding brushes 10 will continue to extend and fit the side of the cut saw teeth 11 to push out the debris between the saw teeth 11, thereby playing a cleaning role.
[0028] The insides of the two grooves 12 are connected with springs 13, and the ends of the two springs 13 are connected to one side of the corresponding protruding brush 10. The springs 13 can keep the protruding brush 10 with a certain degree of elasticity.
[0029] The two fixing ends 3 are provided with engaging grooves on opposite sides thereof, and the two ends of the saw blade 4 are connected to the corresponding engaging grooves respectively.
[0030] Working principle: In the actual operation of the utility model, the user can grab the bow frame 1 through the auxiliary handle 2, and saw the wood or other materials through the saw blade 4 and the saw teeth 11. The anti-slip pattern can prevent the user from slipping when grabbing the auxiliary handle 2.
[0031] In the actual operation of the utility model, when the saw blade 4 cuts the material, the two clamping blocks 5 will drop vertically due to their own gravity and fit against the sides of the saw blade 4. At the same time, the protruding brushes 10 in the two clamping blocks 5 will press the two sides of the saw blade 4 to improve the stability of the saw blade 4 when cutting. At the same time, when the saw blade 4 is gradually embedded in the material, the upper surface of the material will push the two clamping blocks 5 to move upward. Due to the vertical connection of the sliding rod 7, the clamping blocks 5 will slide in the corresponding connecting plate 8 through the sliding rod 7 to prevent the clamping blocks 5 from affecting the cutting of the saw blade 4.
[0032] When the cutting is completed, when the personnel take out the bow frame 1 and the saw blade 4, the two clamping blocks 5 will automatically descend due to their own gravity, and the protruding brushes 10 of the two clamping blocks 5 will descend to the position of the saw teeth 11. Since the thickness of the saw teeth 11 is less than the thickness of the saw blade 4, the protruding brushes 10 will continue to extend and fit the side of the cut saw teeth 11 to push out the debris between the saw teeth 11, thereby playing a cleaning role.
