Embodiment 1
[0020] Such as figure 1 The shown wheel includes a roller 1, a shaft 2 and a bracket 3, and also includes a fixed rod 4 and a clamping groove 7; the roller 1 is connected to the movable axis of the shaft 2, and the two ends of the shaft 2 are respectively fixedly connected to a bracket 3 and a clamping groove. There is a connecting hole through the clamping groove on the side, the fixing rod 4 passes through the connecting hole, and the inner wall of the connecting hole has a thread that matches the outer wall of the fixing rod 4; two brackets 3 are fixedly connected to the bottom cloth of the clamping groove 7, and the opening of the clamping groove 7 is upward , suitable for gripping vertically placed objects.
[0021] On this basis, there is a handle 5 that can be twisted by hand on the outside of the fixed rod 4, and a gasket 6 is provided on the side of the fixed rod 4 and the clamp groove 7; when there is no object in the clamp groove, the fixed rod 4 is twisted The pad...
Embodiment 2
[0024] Such as figure 2 The difference between the shown wheel and Embodiment 1 is that the bracket is placed on the side of the clamping groove 7, and the clamping groove faces the horizontal direction, which is suitable for clamping horizontally placed objects.
Embodiment 3
[0026] Such as image 3 The difference between the shown wheel and Embodiment 1 is that the outside of the clamping groove 7 is semicircular, the clamping groove 7 and the bracket 3 are movably connected through the sliding track 8 arranged at the bottom of the clamping groove 7, and the track fixing device 9 is arranged on The clip groove 7 corresponds to one side of the sliding track 8 . Wherein, the rail fixing device 9 is a fixing device composed of screws and nuts. Loosening the nut allows the clip groove 7 to slide along the slide groove 8, and after the clip groove 7 turns to a suitable angle, tighten the nut so that the slide rail 8 can be fixed.
