[0032] Referring to Figures 7-12 In the embodiment, the first corridor groove 4 is arranged on the front and rear ends of the upper slide rail frame 2, the two-section support arm 19 is rotatably connected to the front and rear ends of the pad arm lower sliding block 26, the upper rotating seat 18 is rotatably connected to the upper end of one side of the two-section support arm 19, the negative pressure cavity 16 is fixedly connected to one side of the upper rotating seat 18, the dust suction pipe 17 is connected to the dust collector, the dust collector is started when the cover plate 14 is closed, the external air enters the space between the sliding chuck 6 and the cover plate 14 due to the negative pressure from the gap between the sliding chuck 6 and the cover plate 14 and the gap between the exposed groove 12 and the cover plate 14, so that the dust attached to the copper plate 8 enters the dust suction port 15 and the negative pressure cavity 16 along with the airflow, and enters the dust collector through the dust suction pipe 17, so as to complete the cleaning of the copper plate 8 and ensure the normal operation of the copper plate 8. The cover plate 14 is fixedly connected to one side of the negative pressure cavity 16, the dust suction pipe 17 is installed at the front end of the negative pressure cavity 16, a plurality of dust suction ports 15 are arranged on the cover plate 14, the lower end of the cover plate 14 is rotatably connected to the sliding chuck 6, and the first corridor groove 4 is slidably connected to the two-section support arm 19.

[0033] Preferably, the lower end of the dust suction pipe 17 is provided with a second corridor groove 28, the second corridor groove 28 is arranged on the cutting table 1, the dust suction pipe 17 is slidably connected to the second corridor groove 28, the front and rear ends of one side of the lower slide rail frame 20 are provided with a sliding groove 29, the sliding groove 29 is arranged on the cutting table 1, and the lower slide rail frame 20 is slidably connected to the sliding groove 29. The electric sliding rail 30 is installed on the side end surface of the cutting table 1, the electric saw 31 is slidably connected to one side of the electric sliding rail 30 through the electric sliding block, and the lower end surface of the electric saw 31 is slidably connected to the cutting table 1. After the wood is clamped and positioned by the sliding chuck 6, the electric saw 31 is started, and the electric sliding rail 30 is started to displace the electric saw 31 left and right, so as to cut the front end of the wood at the same time when the electric saw 31 is displaced.

[0034] In use, first, the wood is placed on the upper end surface of the cutting table 1, and then the upper lead screw 3 is indirectly rotated by the slide rail motor 25 to move the sliding chuck 6 leftward on the upper lead screw 3, so that the sliding chuck 6 is close to the wood and clamps the wood together with the cutting table 1. During this process, if the hand contacts the clamp, the exposed slot 12 will increase the probability of the hand first contacting the copper plate 8. The copper plate 8 serves as an electrode of the capacitance sensor 11, so that the capacitance sensor 11 can detect the capacitance change of the copper plate 8 when the hand contacts the copper plate 8. Subsequently, the slide rail motor 25 and the upper lead screw 3 are stopped by the capacitance sensor 11 to avoid the sliding chuck 6 continuing to displace and pressing the hand, causing the hand to be injured. When the sliding chuck 6 and the abutment column 13 contact and clamp the wood, the sliding plate 7 and the roller 9 will retract into the sliding chuck 6 due to being pushed, so as to avoid the copper plate 8 and the wood from being rubbed. The spring guide rod 10 is used to automatically reset the sliding plate 7. After the wood is clamped by the sliding chuck 6 to complete positioning, the electric saw 31 is started, and the electric slide rail 30 is started to displace the electric saw 31 left and right, so as to cut the front end of the wood while the electric saw 31 is displaced;

[0035] After the slide rail motor 25 is started, the slide rail motor 25 drives the double-end smooth lead screw 21 and the toothed groove shaft 23 to rotate in the positive direction through the second bevel gear 24 and the first bevel gear 22. The toothed groove shaft 23 drives the upper lead screw 3 to rotate in the reverse direction through the gear shaft 5, so as to move the sliding chuck 6 leftward on the upper lead screw 3 while moving the pad arm lower block 26 rightward on the double-end smooth lead screw 21, so as to lower the two-section support arm 19 through the upper rotating seat 18 and open the cover plate 14. The above steps are reversed to close the cover plate 14. When the sliding chuck 6 is displaced, the lower slide rail frame 20 fixedly connected with the sliding chuck 6 will displace in the same direction as the sliding chuck 6 with the pad arm lower block 26. In addition, because the gear diameter of the gear shaft 5 is greater than the diameter of the toothed groove shaft 23, the rotating speed of the toothed groove shaft 23 is greater than the rotating speed of the upper lead screw 3, the sliding speed of the pad arm lower block 26 is greater than the sliding speed of the sliding chuck 6, and the opening and closing speed of the cover plate 14 is greater than the sliding speed of the sliding chuck 6;

[0036] When the cover plate 14 is fully opened, one side of the pad arm lower sliding block 26 will be against the inner wall of one side of the lower sliding rail frame 20, so as to increase the stability of the two-stage support arm 19 supporting the cover plate 14 while keeping the cover plate 14 vertical to the sliding clamp 6, so that one side of the wood can be placed on the upper end of the opened cover plate 14, and when the cover plate 14 is closed, the other side of the pad arm lower sliding block 26 will be against the inner wall of the other side of the lower sliding rail frame 20, when the pad arm lower sliding block 26 is against the inner wall of the lower sliding rail frame 20, because the pad arm lower sliding block 26 has been transferred from the thread of the double-end smooth lead screw 21 to the smooth part, so the pad arm lower sliding block 26 will not continue to move on the double-end smooth lead screw 21 due to the rotation of the double-end smooth lead screw 21, but only synchronously displace with the sliding clamp 6 and the lower sliding rail frame 20 as a whole, until the double-end smooth lead screw 21 is reversed by the sliding rail motor 25, the pad arm lower sliding block 26 will be pushed back to the thread of the double-end smooth lead screw 21 by the second spring 27, and move reversely on the double-end smooth lead screw 21;

[0037] The dust suction pipe 17 is connected with the dust collector, when the cover plate 14 is closed, the dust collector can be started, the external air enters between the sliding clamp 6 and the cover plate 14 due to the negative pressure from the gap between the sliding clamp 6 and the cover plate 14, and the gap between the exposed groove 12 and the cover plate 14, so that the dust attached to the copper plate 8 enters the dust suction port 15 and the negative pressure cavity 16 with the airflow, and enters the dust collector through the dust suction pipe 17, so as to complete the cleaning of the copper plate 8 and ensure the normal operation of the copper plate 8.

[0038] Through the above steps, by setting the sliding clamp 6, the sliding plate 7, the copper plate 8, the roller 9 and the capacitive sensor 11, after the wood is placed on the upper end surface of the cutting table 1, the sliding rail motor 25 is indirectly rotated to rotate the upper lead screw 3, so that the sliding clamp 6 approaches the wood, and the sliding clamp 6 clamps the wood together with the cutting table 1, if the hand contacts the clamp during the process, the exposed groove 12 will increase the probability of the hand contacting the copper plate 8 first, the copper plate 8 as the electrode of the capacitive sensor 11, so that the capacitive sensor 11 can detect the capacitance change of the copper plate 8 when the hand contacts the copper plate 8, then the sliding rail motor 25 and the upper lead screw 3 are stopped by the capacitive sensor 11, so as to avoid the sliding clamp 6 continuing to displace and pressing the hand, which can cause hand injury, when the sliding clamp 6 and the abutting column 13 contact and clamp the wood, the sliding plate 7 and the roller 9 will be pushed into the sliding clamp 6 to avoid the copper plate 8 rubbing with the wood, and the spring guide rod 10 is used for automatically resetting the sliding plate 7, so that the clamp can automatically sense the contact between the hand and the clamp, and stop moving in time, so as to reduce the probability of the hand being squeezed by the clamp and being injured.
