A connecting rod 212 is installed on one side of the movable frame 204, and a sliding groove 213 is provided on one side of the fixed box 203. The connecting rod 212 is slidably connected inside the sliding groove 213, and an annular plate 214 is installed on the top side of the adjusting plate 103. A slot 215 is provided on the inner side of the annular plate 214, and the plug block 207 is plugged into the slot 215, so that the angle of the mechanical parts can be quickly adjusted and the angle limit effect can be achieved, which can effectively avoid the shaking and offset phenomenon when the staff repairs the mechanical parts, greatly improve the efficiency of the staff in repairing the mechanical parts, and bring convenience to the staff when using;

[0027] A pointer 216 is installed on one side of the fixed sleeve 202, and an annular scale 217 is installed on the outside of the annular plate 214. The pointer 216 is rotated by the rotation of the rotating rod 201. At this time, the staff observes the pointer 216 and the annular scale 217, so as to achieve the effect of precise adjustment of the angle of the mechanical parts, and the staff can quickly and accurately adjust the mechanical parts of the same specification, which brings practicality to the staff when using. The inner side of the workbench 1 is rotatably connected with a bidirectional screw 218, and the bottom end of the hollow plate 102 is located at the outer sides of the two ends of the bidirectional screw 218 and is threadedly connected, and a sliding sleeve 219 is installed at the bottom end of the hollow plate 102, and the inner space between the sliding sleeve 219 is large.

[0029] Working principle: Before using this multifunctional positioning fixture for machining, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, when the staff rotates the rotating rod 201 to drive the mechanical claw 104 to rotate, the mechanical claw 104 drives the mechanical parts to flip at multiple angles. At this time, the rotating rod 201 drives the fixed sleeve 202 to rotate, and the rotation of the fixed sleeve 202 drives the fixed box 203 to rotate. When the angle adjustment of the mechanical parts is completed, the staff pulls the connecting rod 212 to slide inside the slide groove 213. The movement of the connecting rod 212 drives the movement of the movable frame 204, and the movement of the movable frame 204 drives the movement of the connecting plate 205. At this time, the distance between the two sets of rotating seats 209 changes. At this time, the retraction rod 210 and the first telescopic spring 211 contract, and by loosening the connecting rod 212, and then through the reset of the first telescopic spring 211, the arc plate 206 can be fitted with the inner side of the annular plate 214. At this time, multiple sets of plug-in blocks 207 are plugged into the slots 215, so as to achieve the effect of quickly adjusting the angle of the mechanical parts and the angle limit, which can effectively avoid the staff from accidentally touching the mechanical parts. The staff can quickly and accurately adjust the mechanical parts of the same specification, which brings practicality to the staff when in use. The staff rotates the bidirectional screw 218 to drive the relative movement of the hollow plate 102. At this time, the movement of the hollow plate 102 drives the movement of the sliding sleeve 219. At this time, the sliding sleeve 219 is located on the outside of the support rod 220 and slides, so that the two sets of mechanical claws 104 can move stably and approach each other, thereby achieving the effect of clamping and limiting mechanical parts of various specifications, greatly improving the applicability of the device and bringing convenience to the staff when in use. The design of the handle 221 makes it easy for the staff to operate the bidirectional screw 218.

[0030] The staff slides the adjustment plate 103 inside the top of the hollow plate 102. When the mechanical claw 104 reaches the target height, the staff rotates the rotating block 303 to drive the rotation of the threaded rod 302. At this time, the threaded rod 302 is located inside the bracket 301 and the threaded rotation is caused. Since one end of the threaded rod 302 is rotatably connected to the slide plate 304, the rotation of the threaded rod 302 drives the slide plate 304 to slide on the outside of the bracket 301. The movement of the slide plate 304 drives the movement of the insertion rod 305. At this time, one end of the insertion rod 305 is plugged into the slot 306, so as to achieve the effect of quickly adjusting the height of the limit adjustment plate 103, and then the mechanical claw 104 can meet the effect of clamping mechanical parts of various specifications, and the limit of the adjustment plate 103 can improve the stability of the mechanical claw 104 during use, which brings convenience to the staff during use.
