If desired, the second clamping bar 300 may be provided with a set screw stop to assist in fixing the position of the second clamping bar 300. Of course, when the first clamping bar 200 and the floating clamp 500 clamp the workpiece, the second clamping bar 300 is stressed and the position on the supporting bar 100 is not changed. The other end of the second clamping bar 300 is provided with a fixing hole 310, and the hole diameter of the fixing hole 310 is matched with the hole diameter of the middle section 610 of the rotating shaft 600, namely, interference fit or transition fit is carried out, so that the fixed or rotatable connection between the second clamping bar 300 and the rotating shaft 600 is realized.

In this embodiment, the involute transitions between the relaxation face 420 and the clamping face 430; other circular arc transitions may of course be used. In this embodiment, the loosening surface 420 and the clamping surface 430 are switched by rotating the handle 400 about the rotation axis 600 by 90 degrees, but other angles may be used.
In this embodiment, the handle 400 is composed of a left handle casing 401 and a right handle casing 402, and the left handle casing 401 and the right handle casing 402 may be fixed together by a fastener, an interference fit, or a snap fit. The handle 400 is formed by a left shell and a right shell, so that the loose return spring 700 is placed in the middle, and the assembly is convenient. As shown in fig. 4, the handle right housing 402 has a torsion spring slot 440 therein, and the handle left housing 401 also has a corresponding torsion spring slot 440 therein. The torsion spring is arranged between the handle left shell 401 and the handle right shell 402, and two ends of the torsion spring are embedded in the torsion spring groove 440.
As shown in fig. 3, 5 and 6, the floating clip 500 has a floating hole 510; the floating hole 510 is a long circular hole. Of course, the floating hole 510 may have other shapes as long as the width of the floating hole 510 matches the diameter of the end 620 of the rotation shaft 600 and the length is longer than the diameter of the end 620 of the rotation shaft 600; i.e., the floating hole 510 and the rotation shaft 600 are relatively movable. Specifically, in the present embodiment, the rotation shaft 600 is relatively fixed as a reference, and the floating hole 510 of the floating clip 500 moves up and down on the end 620 of the rotation shaft 600.
In this embodiment, the floating clip 500 is comprised of two risers 520 and one cross plate 530. Two ends of the horizontal plate 530 are respectively perpendicular to the two vertical plates 520; the floating holes 510 penetrate the two risers 520. It should be noted that the two vertical plates 520 and the one horizontal plate 530 are integral, and the division into three parts is only for convenience of describing the shape of the floating clip 500. The handle 400 and the second clamping bar 300 are disposed between two risers 520. The width of the floating hole 510 is matched to the size of the end 620 of the rotation shaft 600; the floating holes 510 on the two vertical plates 520 are respectively sleeved on the end parts 620; and the riser 520 has the same width as the end 620 of the rotation shaft 600.
The floating clamp 500 has a floating clamping plane on the upper surface of the cross plate 530, i.e., the side opposite to the first clamping bar. The first clamping plane 210 is parallel to the floating clamping plane; and the first clamping plane 210 and the floating clamping plane are perpendicular to the support bar 100.
In this embodiment, the floating clamp 500 is provided as two parts of a floating clamp left case 501 and a floating clamp right case 502 for convenience of assembly. The floating clamp left shell 501 and the floating clamp right shell 502 are symmetrical L-shaped. The left and right shells 501 and 502 of the floating clamp are sleeved on the two sides of the second clamping bar 300 and the handle 400 from two sides, and the loose surface 420 or the clamping surface 430 of the handle 400 is pressed against the lower surface of the transverse plate 530 of the floating clamp 500. While the end 620 of the rotation shaft 600 is inserted into the floating hole 510. The floating clamp left shell 501 and the floating clamp right shell 502 are fixed together in a tight fit or clamping manner.
In fact, the rotation shaft 600 may be a cylinder with the same front and rear diameters, and the width of the floating hole 510 may be the same as the fixed hole 310 and the rotation hole 410. In this way, it is only necessary to provide two blocking plates in the floating clip 500 to prevent the rotation shaft 600 from moving left and right. Of course, the width of the vertical plate 520 of the floating clip 500 may be increased so that the floating hole 510 does not penetrate the vertical plate 520, and the rotation axis is also prevented from moving left and right.
The working process of the quick F clamp is as follows:
when the quick F-clamp is required to clamp a workpiece, the workpiece is placed between the first clamping plane 210 of the first clamping bar 200 and the floating clamping plane 520 of the floating clamp 500. As shown in fig. 1 and 5, the slack side 420 of the handle now rests on the floating clip 500. Rotating the handle 400 clockwise, the loosening face 420 rotates to the clamping face 430 against the floating clamp 500, in the process, the distance from the rotating shaft 600 to the floating clamp increases, the rotating shaft 600 is relatively fixed, and therefore, the floating clamp 500 is lifted up to move close to the first clamping bar 200, clamping the workpiece between the first clamping bar 200 and the floating clamp 400, as shown in fig. 2 and 6.
When the quick F-clamp is required to release a workpiece, as shown in fig. 2 and 6, the clamping surface 430 of the handle abuts against the floating clamp 500, the handle 400 is rotated counterclockwise, the clamping surface 430 rotates until the loosening surface 420 abuts against the floating clamp 500, the distance from the rotating shaft 600 to the floating clamp is reduced in the process, the force driving the floating clamp 500 to approach the first clamp rod 200 is removed, and the workpiece can be easily removed.
The slack return spring 700 is provided to prevent the handle 400 from generating a driving force to the floating clip 500 in an inoperative state by gravity. When the clamping surface 430 rotates to the loosening surface 420 to abut against the floating clamp 500, the loosening return spring 700 drives the handle 400 to return, and the state shown in fig. 1 is always maintained.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Any creation of the utility model without exceeding the scope of the essential spirit of the present invention, including but not limited to the change of the number of the components, the structure of the self-locking buckle, and other insubstantial replacements, variations or modifications, all fall within the protection scope of the present invention.
