[0025] Further, each inner clamping claw mechanism 4 includes an L-shaped block 14, an arc-shaped clamping claw 15, a C-shaped slider 16, a slider 2 161, a fixed block 17, a slide groove 2 18, and a spring 19;

[0026] Furthermore, one end of the L-shaped block 14 is rotatably installed in the positioning block 13 set on one side of the inner positioning disk 3, and the upper end of the L-shaped block 14 is limited by a fixed block 17 and a C-shaped slider 16 is installed, arc-shaped clamping claws 15 are installed on both sides of the C-shaped slider 16, and a spring 20 is installed at the bottom of the other end of the L-shaped block 14, and the other end of the spring 20 is connected to the bottom wall of the inner positioning disk 3.

[0027] Furthermore, a slide groove 9 is provided on one side of the upper part of the mounting column 2, and a slider 10 is installed in the slide groove 9 for limited sliding. One end of the slider 10 is rotatably connected to the double-head clamping claw 11, and the other end is provided with a screw hole, and an adjusting screw 8 is screwed into the screw hole. The adjustment function of the slider 10 is realized by the adjusting screw 8, thereby realizing the extrusion clamping of the outer wall of the receiver.

[0028] Furthermore, an adjusting block 7 is installed on one side of the upper part of the mounting column 2, a screw hole is opened in the middle of the adjusting block 7, an adjusting screw 8 is screwed into the screw hole, one end of the adjusting screw 8 is screwed to the slider 10, and the other end is fixedly connected to the handle 5.

[0029] Furthermore, a clamping groove 101 is provided in the middle of the slider 10 , and a double-headed clamping claw 11 is rotatably installed inside the clamping groove 101 via a rotating shaft 12 , and there is a gap between the double-headed clamping claw 11 and the inner wall of the clamping groove 101 .

[0030] Furthermore, a positioning block 13 is installed on one side of the upper portion of the inner positioning plate 3 , and an L-shaped block 14 is rotatably installed on the inner wall of the positioning block 13 .

[0031] Furthermore, two slide grooves 18 are provided on both sides of the fixed block 17 , and a C-shaped slider 16 is slidably installed in the slide groove 18 via a slider 161 , and the C-shaped slider 16 is connected to the fixed block 17 via a spring 19 .

[0032] In the present embodiment, the thin-walled receiver body 6 is placed on the base 1 through the inner positioning plate 3, and the inner clamping claw mechanism 4 on the inner positioning plate 3 effectively clamps the bottom inner wall of the thin-walled receiver body 6 through the arc-shaped clamping claw 15, and by rotating the handle 5, the adjusting screw 8 drives the slider 10 to move, so that the double-headed clamping claw 11 clamps the outer wall of the thin-walled receiver body 6, and then stably clamps the upper and lower walls of the thin-walled receiver body 6, thereby ensuring processing stability and avoiding damage to the workpiece.

[0033] Among them, in actual use, when the L-shaped block 14 in the inner clamping claw mechanism 4 is subjected to the downward pressure from the thin-walled receiver body 6, the L-shaped block 14 rotates through the rotating shaft connected to the positioning block 13, and the L-shaped block 14 flips to one side, so that the arc-shaped clamping claw 15 arranged on the upper part of the L-shaped block 14 presses the inner wall of the thin-walled receiver body 6. During the pressing process, the C-shaped slider 16 slides in the slide groove 2 18 opened on both sides of the fixed block 17 through the slider 2 161, and the spring 1 19 at the front end is compressed and applies a reverse force to the arc-shaped clamping claw 15, so that the arc-shaped clamping claw 15 stably clamps the inner wall of the thin-walled receiver body 6, and due to the weight of the thin-walled receiver body 6 itself, the arc-shaped clamping claw 15 can clamp its inner wall very stably; at the same time, the spring 20 arranged at the bottom can ensure its reset function.

[0034] Among them, in actual use, the handle 5 drives the adjusting screw 9 to rotate, and the adjusting screw 9 drives the slider 10 to move horizontally under the action of the rotation of the thread, and completes the clamping operation of the thin-walled receiver body 6. When the double-headed clamping claw 11 contacts the thin-walled receiver body 6, since the double-headed clamping claw 11 is connected to the slider 10 through the rotating shaft 12, and there is a certain gap between the double-headed clamping claw 11 and the clamping groove 101, it can effectively adapt to the shape of the thin-walled receiver body 6, and can perform adaptive fine-tuning rotation during clamping to complete a stable clamping operation.

[0035] In the utility model, by arranging the components such as the mounting column 2, the double-headed clamping claw 11, the inner positioning plate 3, the inner clamping claw mechanism 4, etc., when the thin-walled receiver body 6 is clamped, the upper and bottom parts of the thin-walled receiver body 6 can be effectively clamped stably and evenly, and the adjustment process is convenient and the force is evenly applied, which effectively improves the strength and stability of the clamping and fixing, reduces the processing difficulty, avoids damage to the receiver body, and ensures the processing accuracy and technical conditions.
