Traditional anchor clamps, for example the F that has the handle presss from both sides, and its handle generally sets up in the both sides that deviate from each other with the clamping face, produces position interference with treating centre gripping structure or workstation easily in the use, has influenced the applicable scene of anchor clamps. If a woodworking operation is expected on the workbench, only other tools with clamping structures can be selected, or the edge of the workbench is grooved to give way to the handle of the F-shaped clamp, or the first clamping surface is raised to enable the handle of the F-shaped clamp to be placed on the table top of the workbench for use.

However, the use method of the F clamp in cooperation with the workbench cannot be adapted to the existing workbench or cannot ensure the stability of the F clamp in use.

Based on this, please refer to fig. 2 and fig. 4 together, fig. 2 is a schematic diagram of a partial structure of the clamp 100 shown in fig. 1 (a cover plate on the movable clamp body 30 is omitted to show an internal structure); fig. 4 is a cross-sectional view of the fixture 100 shown in fig. 1. In the clamp 100 provided by the present invention, the movable clamp 30 further includes an operation portion 302, and the movable clamp 30 can be adjusted on the rod 10 by the operation portion 302; the operating portion 302 and the second clamping surface 301 are located on the same side of the rod body 10.

Specifically, the operating portion 302 includes a moving portion 31 and a clamping portion 32, the movable clamp 30 further includes a second support portion 33, both the moving portion 31 and the clamping portion 32 are mounted on the second support portion 33, and the movable clamp 30 can move along the rod 10 through the moving portion 31; the movable clamp 30 can move along the rod 10 by the clamping portion 32 in a direction to approach the fixed clamp 20 and apply a pressing force to the clamped structure.

The moving portion 31 includes a locking piece 311 and a first elastic member 312, the locking piece 311 and the first elastic member 312 are both mounted on the second supporting portion 33, a second hole (not shown) is formed in the locking piece 311, the locking piece 311 is sleeved on the rod body 10 through the second hole, and the locking piece 311 can rotate relative to the rod body 10. The two ends of the first elastic element 312 are respectively abutted against the locking piece 311 and the second supporting portion 33, and the first elastic element 312 can enable the locking piece 311 to be reset to the state that the inner wall of the first hole 11 clamps the rod body 10.

When the user presses the locking piece 311, the locking piece 311 rotates and is gradually perpendicular to the rod body 10, and the inner wall of the second hole gradually leaves the rod body 10, at this time, if the user applies a force along the direction of the rod body 10, the moving portion 31 can move along the rod body 10 in a direction relatively close to or relatively far away from the fixing clip body 20. When the user releases the locking piece 311, the locking piece 311 is reset under the action of the first elastic piece 312, and the locking piece is restored to the state that the inner wall of the second hole clamps the rod body 10, so that the positioning of the moving part 31 is realized.

It should be noted that, in the state that the inner wall of the second hole is located at the clamping rod 10, when the movable clamp 30 tends to move away from the fixed clamp 20, under the action of inertia, the inner wall of the second hole tends to further clamp the rod 10, so as to ensure that the movable frame cannot move in a direction relatively away from the fixed clamp 20. On the contrary, when the movable clamp 30 has a tendency to move close to the fixed clamp 20, the inner wall of the second hole has a tendency to release the rod 10 under the action of inertia, so as to ensure that the clamping portion 32 can drive the movable clamp 30 to move close to the fixed clamp 20.

Preferably, the number of the locking pieces 311 is at least two, the toggle member can drive one of the locking pieces 311 to rotate, and the other locking pieces 311 are driven by the locking piece 311 to rotate along with the rotation.
