2. Description of the Related Art Conventionally, a block or a jack has been used as a supporting device for supporting a work on a worktable at a predetermined height.

As shown in FIG. 17, for example, a block 71 having a rectangular parallelepiped shape is used as the block, and the work W is set at three levels by setting up the block 71 using three surfaces having different sizes. To support.

As shown in FIG. 18, for example, a screw type jack 72 is used as a jack, and a screw 721 for adjusting the height of the jack 72 is turned to determine the position of a screw head 722 which is a support surface for the work W. By adjusting the height to an appropriate height, the work W is supported at a predetermined height.

Conventionally, a supporting device has been used in combination with a clamping device for clamping works of various heights on a worktable, and various types of blocks and jacks have been used for this supporting device.

As the block, for example, as shown in FIG. 19, a stepped block 81 is used. The block 81 is formed as a substantially triangular prism as a whole, and a plurality of steps 811 are formed in a step shape on the slope. The work W is clamped by placing one end of the clamp S of the clamp device on the work W on the worktable and supporting the other end of the step S 811 of the stepped block 81 at a predetermined height. The block also uses a clamping block 82, for example, as shown in FIG. In this block 82, a plurality of plates 821 are stacked, and these are connected through one shaft 822 so that each plate 821 can rotate. The work W is clamped by placing one end of the clamp S of the clamp device on the work W on the worktable and supporting the other end with a required number of plates 821.

As shown in FIG. 21, for example, a screw-type jack 83 is used as the jack. One end of the clamp S of the clamp device is placed on the work W on the worktable, and the other end is required. Screw head 831 adjusted to height
The workpiece W is clamped by being supported by the supporting surface of the workpiece W.

However, the above-mentioned conventional supporting device has the following problems. (1) In the case of the rectangular parallelepiped block shown in FIG. 17, the height adjustment is limited to three steps, so that it is impossible to cope with various work heights. (2) In the case of the screw type jack shown in FIG. 18, it is difficult to adjust the height adjusting screws of all jacks used for supporting the work to the same height. (3) In the case of the stepped block shown in FIG. 19 and the clamping block shown in FIG. 20, fine adjustment cannot be made according to the height of the work, so that a special strap or washer must be used for the clamping device. (4) In the case of the screw type jack shown in FIG. 21, since the screw for adjusting the height is turned according to the height of the work, the adjustment is not easy.
