[0018] See also Figure 2 and Figure 3 In the figure, the transmission mechanism includes a square groove 12, which is opened in the inner wall of the machine table 4, and the front end of the square groove 12 is rotatably connected with a stud 13, the stud 13 movably passes through the rear end of the machine table 4, and the rear end of the stud 13 is fixedly connected with the turntable 3, and a block 15 is threadedly sleeved on the outer wall of the stud 13, the block 15 and the square groove 12 are slidably matched, and the upper end of the block 15 is fixedly connected with a slider 14, the slider 14 is slidably set in the upper inner wall of the machine table 4, and the upper end of the slider 14 is rotatably connected to the bottom end of the rotating rod 18.

[0019] See also Figure 1 and Figure 2 In the figure, a slide groove 6 is provided at the upper end of the machine table 4, the slide groove 6 is connected to the square groove 12, and the slider 14 slides in cooperation with the slide groove 6; by providing the slide groove 6, it is convenient for the slider 14 to slide in the inner wall of the upper end of the machine table 4.

[0020] See also Figure 2 In the figure, the rear end of the machine 4 is fixedly connected with a rubber sleeve 11, and the inner wall of the rubber sleeve 11 is tightly fitted with the outer wall of the stud 13; relying on the friction between the rubber sleeve 11 and the stud 13, the stud 13 can maintain a certain fixed state after rotation.

[0021] See also Figure 3 In the figure, the locking assembly includes a fixing block 20, which is fixedly connected to the upper edge of the rear end of the clamp plate 2, and a long bolt 19 is tightened through the inner wall of the fixing block 20, and the long bolt 19 is inserted into and tightened in the upper inner wall of the slider 14.

[0022] See also Figure 2In the figure, the moving mechanism includes a U-shaped seat 10, which is fixedly connected to the upper end of the machine table 4 and located in front of the clamping plate 5, and a screw 17 is screwed through the inner wall of the U-shaped seat 10, one end of the screw 17 is rotatably connected to the front end of the connecting block 8, and the other end of the screw 17 is fixedly connected to the rotating block 7.

[0023] Working principle: the workpiece can be placed between the second clamp plate 5 and the first clamp plate 2. When it is necessary to adjust the fixed angle of the workpiece to change the cross-sectional angle and achieve the required connection or assembly method, rotate the rotating block 7. The rotating block 7 can drive the screw 17 to rotate forward or backward in the inner wall of the U-shaped seat 10, and the screw 17 can drive the connecting block 8 to slide forward or backward on the upper end of the machine table 4. The connecting block 8 can drive the second clamp plate 5 to rotate clockwise or counterclockwise through the connecting plate 16 (the connecting plate 16 will rotate between the connecting block 8 and the second clamp plate 5). The second clamp plate 5 can drive the rotating column 9 to rotate clockwise or counterclockwise on the upper end of the machine table 4 until the second clamp plate 5 is adjusted to the required angle. At this time, the workpiece can fit along the wall surface of the second clamp plate 5.

[0024] Next, the long bolt 19 is rotated upward, and the long bolt 19 can be rotated upward in the inner wall of the fixed block 20 until the lower end of the long bolt 19 leaves the upper inner wall of the slider 14, and then the turntable 3 is rotated, and the turntable 3 can drive the stud 13 to rotate in the square groove 12, and the square groove 12 can drive the square block 15 threaded on its outer wall to slide in the square groove 12 toward the direction of the clamping plate 2 5, and the square block 15 can drive the slider 14 to slide in the direction of the clamping plate 2 5, and the slider 14 can drive the rotating rod 18 and the clamping plate 1 2 to move in the direction of the clamping plate 2 5. Since the clamping plate 2 5 can rotate on the outer wall of the rotating rod 18, the clamping plate 2 5 can adapt to the placement angle of the workpiece and be parallel to the placement angle of the workpiece, and then the workpiece can be fixed between the clamping plate 2 5 and the clamping plate 1 2, thereby improving the flexibility of workpiece processing and bringing convenience.

[0025] It should be noted that when there is no need to adjust the fixed angle of the workpiece, the rotating block 7 is rotated to make the clamp 2 5 rotate to restore to its original state, and then the clamp 1 2 is rotated to its original state, and the long bolt 19 is rotated to tighten the long bolt 19 in the upper end inner wall of the slider 14. At this time, other workpieces that do not need to adjust the fixed angle can be clamped and fixed normally.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
