Still including adjusting shell 11, adjust shell 11 and be cylindric structure, and adjust shell 11's outer wall along circumference equidistant array and seted up a plurality of anti-skidding lines. The inner wall of the adjusting shell 11 close to the bottom is provided with a limiting piece 12 in an integral mode along the circumferential direction, and the outline of the inner wall of the limiting piece 12 is round and smaller than the diameter of the sphere 8. The top of the adjusting shell 11 is provided with a threaded hole 13, and the threaded hole 13 penetrates through the inside of the adjusting shell 11.

As shown in fig. 1 and fig. 4, a clamping mechanism is arranged above the sphere 8, the clamping mechanism comprises a first clamp body 14 and a second clamp body 15, the first clamp body 14 is of a block structure with an L-shaped longitudinal section, and the second clamp body 15 is of a cuboid structure. The second jaw body 15 slides horizontally on top of the first jaw body 14. The top surfaces of the first clamp body 14 and the second clamp body 15 are positioned at the same height. Five blind holes 16 are respectively formed in the tops of the first clamp body 14 and the second clamp body 15, and the positions of the five blind holes 16 of the first clamp body 14 and the positions of the five blind holes 16 of the second clamp body 15 are mutually symmetrical. The clamping rod 6 can be inserted into the blind hole 16, and the height of the clamping rod 6 in the blind hole 16 is higher than the height of the top surface of the clamp body.

A threaded rod 17 is vertically fixed at the bottom of the first clamp body 14, and the threaded rod 17 is in threaded connection with the threaded hole 13 of the adjusting shell 11. The second clamp body 15 is horizontally and slidably connected to the top surface of the platform of the first clamp body 14.

Another clamping method is that a user uses fingers to draw the first clamp body 14 and the second clamp body 15 close to each other to clamp the workpiece. Since the movable rod 22 slides with the first clamp body 14 and the movable rod 22 is in threaded connection with the second clamp body 15, the movable rod 22 can slide synchronously with the second clamp body 15, and the compression spring 19 is also compressed and shortened in the process. When the clamping is completed, the user releases the fingers, and the first clamp body 14 and the second clamp body 15 are separated and reset again under the action of the compression spring 19. Finally, the bench clamp is fast clamped and separated.

As shown in fig. 6, when the ball workpiece is required to be clamped, a user stretches fingers from the extracting groove 5 into the accommodating groove 3 to pick up the four clamping rods 6. Then, the four clamping rods 6 are symmetrically placed on the top of the first clamp body 14 and the second clamp body 15 in a one-side two-way mode, wherein the distance between the two clamping rods 6 on the same side is smaller than the outer diameter of the ball workpiece. The user then places the ball work piece between the four gripping bars 6. Finally, the first clamp body 14 and the second clamp body 15 are mutually close to realize clamping of the ball workpiece under the close action of the four clamping rods 6.

When the clamping mechanism needs to be disassembled, a user only needs to rotate the adjusting shell 11 to separate the adjusting shell 11 from the threaded rod 17, and then the operator only needs to hold the first clamp body 14 and the second clamp body 15.
