[0017] 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.

[0018] The utility model provides Figure 1 to Figure 3 The shown spliced ​​down-going saw for wood processing includes a connecting rod 1, both ends of which are rotatably provided with vertical rods 2, the connecting rod 1 and the two vertical rods 2 are distributed in an H shape, a saw blade 3 is provided between the bottoms of the two vertical rods 2, the saw blade 3 is assembled according to the existing common technology and will not be elaborated here, and the saw blade 3 is located at the lower end to form a down-going saw structure; a tensioning rope 4 is provided between the tops of the two vertical rods 2, and the tensioning rope 4 is provided, and its tightness is adjustable, and it is tensioned after the saw blade 3 is installed.

[0019] Considering that the lower saw needs to be pulled back and forth during use, if a lateral offset occurs, uneven cuts are likely to occur, and the saw blade 3 may break, especially when segmenting some thicker trees. In order to improve the stability of the lower saw, a J-frame 5 is slidably arranged on the connecting rod 1, and a square plate 6 is arranged above the J-frame 5. A square groove is provided on the square plate 6, and a square column 7 is slidably arranged inside the square groove. The square column 7 is fixedly connected to the top of the J-frame 5, and a circular plate 9 is fixedly connected to the top of the square column 7. A spring 8 is sleeved on the outside of the square column 7, one end of the spring 8 is fixedly connected to the circular plate 9, and the other end of the spring 8 is fixedly connected to the square plate 6. The spring 8 uses a light force spring and does not affect the use of the lower saw. In specific use, when the lower saw is pulled back and forth, the connecting rod 1 slides on the J-frame 5. Due to the limiting effect of the J-frame 5, the connecting rod 1 will not be offset, thereby improving the accuracy of cutting and preventing the saw blade 3 from breaking. As the cut becomes deeper, the connecting rod 1 drives the J-frame 5 to move downward.

[0020] In addition, a ball bearing may be arranged in the J-shaped frame 5 to reduce the friction between the J-shaped frame 5 and the connecting rod 1 and improve the smoothness of the use of the downward saw.

[0021] The square plate 6 is provided with a supporting assembly, which is arranged in multiple groups to realize stable support of the square plate 6. The supporting assembly includes a square tube 10 and a slide plate 11, the square tube 10 is rotatably connected to the square plate 6, and the slide plate 11 is slidably connected to one end of the square tube 10 away from the square plate 6.

[0022] The support assembly further includes a support block 13, a positioning plate 14 and a screw 15. The support block 13 is rotatably connected to the end of the slide plate 11 away from the square tube 10, the positioning plate 14 is fixedly connected to the support block 13, and the screw 15 is threadedly connected to the positioning plate 14. The screw 15 is rotated and inserted into the wood to fix the position of the positioning plate 14. When in use, other fixing methods can be used to fix the position of the positioning plate 14, thereby supporting and positioning the square plate 6.

[0023] The J-shaped frame 5 and the connecting rod 1 are in a spliced ​​structure and can be used selectively.

[0024] The square tube 10 is threadedly connected with a bolt 12, which is located at one end of the square tube 10 away from the square plate 6. The slide plate 11 can slide on the square tube 10 to adjust the support length. After the adjustment is completed, the bolt 12 is rotated to fix the position of the slide plate 11.

[0025] During operation, the slide plate 11 is pulled to slide on the square tube 10 to adjust the support length. After the adjustment is completed, the bolt 12 is turned to fix the position of the slide plate 11, and then the screw rod 15 is turned. The screw rod 15 is inserted into the wood to fix the position of the positioning plate 14, and the square tube 10 and the slide plate 11 complete the support of the square plate 6. During the back and forth pulling of the saw, the connecting rod 1 slides on the J-frame 5. Due to the limiting effect of the J-frame 5, the connecting rod 1 will not be offset, which improves the cutting accuracy and prevents the saw blade 3 from breaking. As the incision becomes deeper, the connecting rod 1 drives the J-frame 5 to move downward, so that the square column 7 and the circular plate 9 move downward synchronously, and the spring 8 is squeezed to contract.
