Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1-3, the utility model provides a swing clamping device includes first arm lock 1, second arm lock 2, swing screw 3, first interlinking axle 4, second interlinking axle 5, handle knob 6, torsional spring 7. The upper part of the first clamping arm 1 is provided with an upper through hole and a lower through hole. The upper through hole corresponds to the second link shaft 5, and the lower through hole corresponds to the first link shaft 4. The left side of the movable joint screw 3 is provided with a circular ring, and the right side is provided with a stud. One side of the handle knob 6 is provided with internal threads, and the internal threads correspond to the stud on the right side of the movable joint screw 3. The two sides of the extension of the torsion spring 7 are at a certain angle, which can be one of an acute angle, an obtuse angle and a right angle, and in the embodiment, the two sides of the torsion spring 7 are at right angles. The movable joint screw 3, the first linking shaft 4, the second linking shaft 5 and the handle knob 6 connect the first clamping arm 1 and the second clamping arm 2 together, in this embodiment, the first linking shaft 4 simultaneously passes through the lower through hole of the first clamping arm 1 and the ring on the left side of the movable joint screw 3, after the stud on the right side of the movable joint screw 3 passes through the second clamping arm 2, the internal thread of the handle knob 6 is matched with the stud on the right side of the movable joint screw 3, the torsion spring 7 is installed on the first clamping arm 1 by the second linking shaft 5, specifically, the second linking shaft 5 passes through the through hole on the second clamping arm 2, the upper through hole of the first clamping arm 1 and the middle circular hole of the torsion spring 7, so that the first clamping arm 1 and the second clamping arm 2 form a movable whole. Two sides of the torsion spring 7 are respectively contacted with the inner side of the upper right corner of the first clamping arm 1 and the inner side of the upper left corner of the second clamping arm 2. The handle knob 6 is provided with an anti-slip groove 10. The top of the second clamping arm 2 is provided with a round linking ball 8. The inner sides of the lower arcs of the first clamping arm 1 and the second clamping arm 2 are provided with a damping rubber pad 9, and the damping rubber pad 9 plays a role in anti-skidding and damping.

As shown in fig. 2, the handle knob 6 is rotated clockwise to rapidly lock the first and

second clamp arms

1 and 2. Specifically, the handle knob 6 rotates clockwise to lock the movable joint screw 3, so as to press the torsion spring 7, and the included angle between two sides of the torsion spring 7 is reduced by taking the second linking shaft 5 as a fulcrum, so that the first clamping arm 1 and the second clamping arm 2 form a clamping and locking state.

As shown in fig. 3, the handle knob 6 is rotated counterclockwise to rapidly release the first and

second clamp arms

1 and 2. Specifically, the handle knob 6 rotates anticlockwise to loosen the swing screw 3, the torsion spring 7 is released, and the included angle between two sides of the torsion spring 7 is increased by taking the second link shaft 5 as a fulcrum, so that the first clamping arm 1 and the second clamping arm 2 form a release opening state.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
