Coaxial clamp

Technical Field

The present invention relates to a coaxial clamp, and more particularly to a clamp, which can be rotated and adjusted by using a guide rod as an axis, so that the clamp can be adjusted to a best clamping point when clamping irregular workpieces.

Background

Generally, when a plurality of boards, such as wood boards, metal boards or plastic boards, are required to be clamped and fixed or processed simultaneously, a fixed fixture (such as a vise) cannot move in accordance with the position of the board, so that a large-sized hand-held fixture is generally used as a clamping tool.

Please refer to taiwan patent document No. M284485 as "improved structure of clamp", which is a gun-type clamp, and the clamp mainly comprises a movable clamp body and a fixed clamp body, wherein the movable clamp body is fixed at an end of a guide rod, the guide rod is slidably disposed on the fixed clamp body, two ends of a bottom edge of the fixed clamp body are respectively protruded with a handle having a release plate and a pressing handle, the actuating plate and the pressing handle can respectively actuate a clamping braking set and a limiting braking set in the fixed clamp body, and the pressing handle is repeatedly pressed to gradually pull the guide rod, so that the movable clamp body and the fixed clamp body are clamped.

As can be seen from the above-mentioned utility model, the conventional gun-shaped clamp is designed to clamp the movable clamp body and the fixed clamp body relatively by pulling the guide rod; however, the conventional gun-shaped clamp has the disadvantages that the angle between the movable clamp body and the fixed clamp body in the clamping direction is fixed, and the clamping point is not good easily when an irregular workpiece is clamped, so that the workpiece is clamped unstably; in addition, the movable clamp body and the fixed clamp body of the conventional gun-shaped clamp are fixed in a non-angle-adjustable manner except for the clamping direction, and the use is easily limited due to the fixed body.

In view of the above, the present invention provides a coaxial clamp, which not only has a conventional gun-type progressive clamping function, but also has an effect of adjusting the clamping angle of the clamp, through long-term research and development, by means of the development experience of many years in the related industries, and through further research and discussion of the problems faced by the conventional gun-type clamp, and through active solution.
