When the cut wood has a certain curvature, the cut wood will be pressed downward against the saw blade under the action of the clamping mechanism, causing the saw blade of the sawing mechanism to get stuck and malfunction.

When the threaded shafts on both sides rotate synchronously, the threaded shafts on both sides are respectively meshed with the connecting frames on both sides. The connecting frames on both sides drive the supporting square tubes to move under the guidance of the guide columns, and the supporting square tubes drive the connecting frames to move. During the movement of the connecting frame, the supporting position of the jacking cylinder is changed, so that the supporting point of the jacking cylinder moves forward, thereby improving the stability of the bearing assembly. By setting up auxiliary components, the supporting point of the bearing assembly can be adjusted according to the specifications of the wood, and the supporting effect of the supporting assembly on the wood is further improved.

[0022] The specific configuration and functions of the bearing component 5 and the auxiliary component 6 are described in detail below.

[0023] In this embodiment: the bearing assembly 5 includes a supporting frame 51, the supporting frame 51 is rotatably connected to the inner wall of the bracket 1, a supporting square tube 52 is installed on the inner wall of the supporting frame 51, a reinforcing rib 53 is fixedly connected to the inner wall of the supporting frame 51, a positioning frame 54 is fixedly connected to the surface of the bracket 1, a lifting cylinder 55 is installed on the inner wall of the positioning frame 54, a connecting frame 56 is fixedly connected to the surface of the supporting square tube 52, and the driving end of the lifting cylinder 55 is rotatably connected to the inner wall of the connecting frame 56.

[0024] Specifically, a square hole is opened on the side surface of the support frame 51, and the supporting square tube 52 is connected to the inner wall of the square hole.

[0025] In this embodiment, the support frame 51 can cooperate with the clamping arm 4 to achieve a clamping effect on the wood, so as to ensure the stability of the wood during processing.

[0026] Specifically, there are multiple reinforcing ribs 53, which are arranged in a circular array about the support frame 51. The reinforcing ribs 53 are triangular in shape. The reinforcing ribs 53 increase the applicability of the support frame 51, so that the support frame 51 can be adapted to wood of different specifications.

[0027] In this embodiment: the auxiliary component 6 includes a limit frame 61, the limit frame 61 is fixedly connected to the side surface of the supporting frame 51, the side surface of the limit frame 61 is fixedly connected with a guide column 62, the surface of the guide column 62 is slidably connected with a connecting frame 63, the connecting frame 63 is fixedly connected to the inner wall of the supporting square tube 52, the inner wall of the limit frame 61 is threadedly connected with a threaded shaft 64, the arc surface of the threaded shaft 64 is fixedly connected with a transmission sprocket 65, the surface of the transmission sprocket 65 is installed with a chain 66, and the side surface of the threaded shaft 64 is fixedly connected with a control handle 67.

[0028] In this embodiment: through the cooperation of the transmission sprocket 65 and the chain 66, when the staff rotates the control handle 67 on one side, the threaded shaft 64 on the other side can be driven to rotate, so that the threaded shafts 64 on both sides can rotate synchronously, which is convenient for the staff's adjustment operation.

[0029] Specifically, there are two limit frames 61, which are mirror-symmetrically arranged with respect to the guide column 62. There are four guide columns 62, which are diagonally arranged with respect to the limit frames 61. Through the cooperation between the limit frames 61 and the guide columns 62, the position of the connecting frame 63 can be supported, and the moving direction of the connecting frame 63 can be guided to ensure the stability of the connecting frame 63 during the movement.

When the clamping arm 4 is frictionally clamped, the lifting cylinder 55 is powered on to work, and cooperates with the connecting frame 56 to push the supporting square tube 52 upward. The supporting square tube 52 pushes the supporting frame 51 to rotate under the action of the lifting cylinder 55 and the connecting frame 56, and the supporting frame 51 gradually approaches the wood. When the supporting frame 51 rotates to a horizontal state, it can support the processed wood under the action of the supporting square tube 52 and the lifting cylinder 55. By setting the bearing component 5, the supporting effect of the clamping mechanism on the wood is increased, thereby reducing the lack of the clamping mechanism. The support for the suspended part of the wood solves the problem that some wood will be stuck in the saw blade when cutting, and further improves the practicality of the clamping mechanism and the stability of the sawing mechanism. In addition, when the wood to be processed is large in size, the operating handle is rotated, and the control handle 67 rotates the transmission sprocket 65 with the cooperation of the threaded shaft 64. The transmission sprocket 65 engages with the chain 66 and drives the other transmission sprocket 65 to rotate. Under the action of the chain 66, the other transmission sprocket 65 drives the other threaded shaft 64 to rotate. When the threaded shafts 64 on both sides rotate synchronously, the threaded shafts 64 on both sides are respectively engaged with the connecting frames 63 on both sides. Under the guidance of the guide column 62, the connecting frames 63 on both sides drive the supporting square tube 52 to move, and the supporting square tube 52 drives the connecting frame 56 to move. When the connecting frame 56 moves, the supporting position of the lifting cylinder 55 will be changed, so that the supporting point of the lifting cylinder 55 moves forward, thereby improving the stability of the bearing component 5. By setting the auxiliary component 6, the supporting point of the bearing component 5 can be adjusted according to the specifications of the wood, and the supporting effect of the supporting component on the wood is further improved.
