The universal joint fork to be processed is clamped and fixed. During the processing, the movable tube seat 2 can be rotated flexibly and conveniently, and then the universal joint fork can be flexibly and conveniently rotated horizontally. Since the clamping block 12 is rotationally connected to the clamping seat 10, the clamping seat 10 can be loosened to rotate the clamping block 12 and the clamped universal joint fork in the longitudinal plane. Since the support screw 7 is slidingly connected to the inside of the movable tube seat 2, the support screw 7 can be conveniently raised and lowered to adjust the height of the universal joint fork, so that the clamp can flexibly rotate the universal joint fork in multiple directions and adjust the height. The high adjustment flexibility can effectively improve the processing flexibility and convenience of the universal joint fork, thereby improving the processing efficiency of the universal joint fork.

[0025] Reference Figure 1, two ends of the track seat 9 are respectively fixedly connected to a fixing block, and a clamping screw 11 is rotatably installed between the two fixing blocks, the clamping screw 11 passes through the threaded holes on the outer surfaces of the two clamping seats 10, and one end of the clamping screw 11 is fixedly connected to a crank, and two threads with opposite spiral directions are arranged on the outer surface of the clamping screw 11, and the two threads are symmetrically distributed with the middle position of the clamping screw 11 as the dividing point, wherein when clamping the universal joint fork, the crank at one end of the clamping screw 11 can be shaken to make the clamping screw 11 rotate, thereby making the clamping seat 10 move along the axial direction of the clamping screw 11, since the clamping screw 11 is provided with two threads with opposite spiral directions, the two clamping seats 10 move toward each other, which can conveniently realize the clamping and loosening operations of the universal joint fork.

[0026] Reference Figure 1 A limiting convex strip is provided on the inner wall of the movable tube seat 2, a limiting groove 8 is provided on the side surface of the support screw 7, and the limiting convex strip is engaged with the inside of the limiting groove 8. The upper end of the movable tube seat 2 is rotatably connected with an adjusting end head 6, and the adjusting end head 6 is threadedly sleeved on the outside of the support screw 7, wherein the adjusting end head 6 can be rotated. Since the adjusting end head 6 is threadedly sleeved on the outer surface of the support screw 7, the support screw 7 is limitedly slidably connected in the sliding part of the movable tube seat 2, so the rotation of the adjusting end head 6 can effectively drive the support screw 7 to move the axial position, thereby flexibly and conveniently adjusting the height of the universal joint fork.

[0027] Reference Figure 1 Two mounting seats 4 are fixedly connected to the upper surface of the supporting base plate 1, a worm 5 is rotatably installed between the two mounting seats 4, a worm wheel 3 is fixed to the outer sleeve of the movable tube seat 2, the worm 5 is meshingly connected with the worm wheel 3, and a handle is fixedly connected to one end of the worm 5, and the handle can be turned to rotate the worm 5. Under the linkage of the worm wheel 3, the movable tube seat 2 rotates, which can effectively improve the orientation of the universal joint fork and improve the convenience of universal joint fork processing.

[0028] Working principle: When in use, first install the clamp at the specified position, then place the universal joint fork to be processed between the two clamping blocks 12, and then rotate the clamping screw 11. Since two threads with opposite spiral directions are arranged on the outer surface of the clamping screw 11, and the two threads are symmetrically distributed with the middle position of the clamping screw 11 as the dividing point, the rotation of the clamping screw 11 can make the two clamping seats 10 move toward each other along the axial direction of the clamping screw 11, so as to clamp and fix the universal joint fork. Before clamping the universal joint fork, the adjusting rod 14 can be moved inside the positioning slot 13 according to the processing needs, and then the universal joint fork can be adjusted to the specified position. The clamping angle of the universal joint fork can be adjusted according to the needs. When adjusting, the adjusting end head 6 can be rotated. Since the adjusting end head 6 is threadedly sleeved on the outer surface of the supporting screw rod 7, and the supporting screw rod 7 is limitedly slidably connected in the sliding of the movable tube seat 2, the rotation of the adjusting end head 6 can effectively drive the supporting screw rod 7 to move the axial position, and then the height of the universal joint fork can be flexibly and conveniently adjusted. After the adjustment is completed, the universal joint fork can be processed. During the processing, the worm 5 can be rotated. Under the linkage of the worm gear 3, the movable tube seat 2 is rotated. At this time, the direction of the universal joint fork can be effectively improved, and the convenience of processing the universal joint fork is improved.
