A top plate is fixedly connected to the top of the base cylinder. A rotating hole is opened at the center of the top of the top plate.
[0008] By adopting the above technical solution, when the electric push rod is activated, the moving plate can be pushed up, so that small steel balls are distributed around the rotating ball, thereby fixing the rotating ball.
[0009] Preferably, the rotating assembly includes a rotating ball, a bottom rod, an upper rod, a clamping groove, an outer retaining groove, and a through hole. The rotating ball is located inside the rotating hole and is rotatably connected to the top plate. The bottom rod is fixedly connected to the bottom of the rotating ball, and the upper rod is fixedly connected to the top of the rotating ball on the same vertical line as the bottom rod. The clamping groove is formed through the front and rear ends of the upper rod. An outer retaining groove is formed on the left side of the upper rod, and a through hole is formed on the right side of the upper rod. The through hole and the outer retaining groove are on the same horizontal line.
[0010] By adopting the above technical solution, the rotating ball can rotate in multiple angles and directions within the rotating hole, with a high degree of adjustment freedom.
[0011] Preferably, the clamp assembly includes a clamping rod, an inner slot, a light hole, a chuck, a lead screw, and a fastening ring. The clamping rod has an inner slot on its left side wall and a light hole on its right side wall. A lead screw is fixedly connected to the right side wall of the chuck, and a fastening ring is threaded onto the lead screw.

[0016] Preferably, the light hole and the through hole are arranged correspondingly, the lead screw passes through the through hole and the light hole, and the fastening ring is located on the right side of the upper rod.
[0017] By adopting the above technical solution, the lead screw passes through the through hole and the light hole. When the fastening ring is loosened, the lead screw can slide horizontally left and right, thereby releasing the limit on the clamping rod and facilitating the adjustment of the clamping rod.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1) By setting a base, a fixed component and a rotating component, the rotating ball in the rotating component can rotate on the top plate and face different directions. After the direction is determined, the electric push rod can be activated to push the moving plate to move up, thereby spreading the small steel balls above the moving plate around the rotating ball, thus limiting the bottom of the rotating ball and fixing the rotating ball, thereby fixing the rotating ball and improving the rotational freedom of the fixture.
[0020] 2) By setting up a rotating component and a clamping component, the rear end of the clamping rod in the clamping component is engaged with the upper rod of the rotating component through a chuck, so that the clamping rod can be fixed during use. When adjustment is required, the fastening ring can be loosened, and then the lead screw can be moved horizontally to release the restriction of the clamping rod by the chuck. Then the clamping rod can be rotated on the vertical plane to adjust the clamping opening and closing degree of the clamping rod. With the help of the rotating ball, a larger angle of clamping can be achieved. Attached Figure Description

The top of the bottom cylinder 201 is fixedly connected to the top plate 205. A rotating hole 206 is opened at the center of the top of the top plate 205.
[0029] When the electric push rod 202 is activated, it can push the moving plate 203 upward, so that the small steel balls 204 are distributed around the rotating ball 301, thereby fixing the rotating ball 301.
[0030] The rotating assembly 3 includes a rotating ball 301, a bottom rod 302, an upper rod 303, a clamping groove 304, an outer retaining groove 305, and a through hole 306. The rotating ball 301 is located inside the rotating hole 206 and is rotatably connected to the top plate 205. The bottom rod 302 is fixedly connected to the bottom of the rotating ball 301. The top of the rotating ball 301 and the bottom rod 302 are fixedly connected to the upper rod 303 on the same vertical line.
