Since the ball body is round, it is necessary to fix the ball body when drawing lines on the pasted rubber outer sheet, so that the upper hemisphere can stably draw lines on the rubber outer sheet. Using an ordinary fixture to fix the ball body will not allow it to rotate. Since the ball body needs to be drawn lines on all sides, we need to design a fixture device for drawing lines on the surface of a rubber ball, which adopts a four-jaw clamping ball and a bottom supporting ball structure to fix the rubber ball outer sheet when drawing lines, and can rotate the ball body arbitrarily in all directions, making the staff more stable when drawing lines, the ball body will not fall off from the fixture, saving time, and thus improving the production quality and efficiency during processing.

Through the combined use of the track 3, the L-shaped sliding plate 4 and the sliding block 12, the fixed round block 14 slides towards each other. Subsequently, the second ball 18 clamps and fixes the lower half of the sphere. Thus, the structure of using four claws to clamp the ball and supporting the ball at the bottom can be achieved to fix the rubber ball outer piece during scribing. The sphere can rotate arbitrarily in all directions, making the staff more stable during scribing, and the sphere will not fall off the fixture, saving time. Therefore, the purpose of improving the production quality and efficiency during processing is achieved.
