[0026] Example:

[0027] like Figs. 1 to 6 As shown, a multi-head F clamp includes an F-structured slide bar 1 and a movable clamping foot 2. The slide bar 1 is equipped with a slidable and adjustable movable clamping foot 2 on its transverse structural portion. A first screw 6 is threaded through the lower end of the movable clamping foot 2. A first pressure foot 5 is mounted on the left end of the first screw 6. A first cross arm 7 is passed through the right end of the first screw 6. A multi-head mechanism 3 is provided on the slide bar 1 to the right of the movable clamping foot 2.

[0028] The multi-head mechanism 3 includes a movable seat 31, a movable arm 33, a second pressure foot 34, a second screw 35 and a second cross arm 36. The movable seat 31 is sleeved on the slide rod 1. Two groups of movable arms 33 are hinged on the lower side of the movable seat 31. The lower end of each group of movable arms 33 is threaded with a second screw 35. The left end of the second screw 35 is installed with a second pressure foot 34 of the same specification as the first pressure foot 5, and the right end of the second screw 35 is penetrated by a second cross arm 36. This design solves the problem that the existing F clamp can usually only clamp a single workpiece during operation. When two or more workpieces need to be clamped at the same time, multiple F clamps must be used to clamp them separately, which not only increases the complexity of the operation, but also makes it extremely inconvenient to carry and use.

[0029] In the embodiment, the utility model can clamp multiple different workpieces at the same time through the additional multi-head mechanism 3, and the clamping range is wide, which greatly improves the work efficiency and convenience of use, and the movable clamping foot 2 and the movable arm 33 in the multi-head mechanism 3 can be flexibly adjusted to adapt to workpieces of different sizes and shapes.

[0030] In the embodiment, the movable seat 31 is internally provided with a jaw 32 matched with the slide rod 1, and the movable seat 31 is sleeved on the slide rod 1 and is in sliding connection with the slide rod 1 through the jaw 32. The jaw 32 is arranged to enable the movable seat 31 to be matched and connected with the slide rod 1, thereby ensuring the stable installation of the movable seat 31 on the slide rod 1 and preventing loosening or deviation of the movable seat 31 due to vibration or external force during use. Meanwhile, the cooperation between the jaw 32 and the slide rod 1 allows the movable seat 31 to smoothly slide on the slide rod 1, and such a sliding connection enables the user to easily adjust the position of the movable seat 31 as needed to adapt to workpieces of different sizes or shapes.

[0031] In the embodiment, the movable seat 31 is internally provided with a jaw 32 matched with the slide rod 1, and the movable seat 31 is sleeved on the slide rod 1 and is in sliding connection with the slide rod 1 through the jaw 32. The jaw 32 is arranged to enable the movable seat 31 to be matched and connected with the slide rod 1, thereby ensuring the stable installation of the movable seat 31 on the slide rod 1 and preventing loosening or deviation of the movable seat 31 due to vibration or external force during use. Meanwhile, the cooperation between the jaw 32 and the slide rod 1 allows the movable seat 31 to smoothly slide on the slide rod 1, and such a sliding connection enables the user to easily adjust the position of the movable seat 31 as needed to adapt to workpieces of different sizes or shapes.

[0032] In the embodiment, the movable seat 31 is internally provided with a jaw 32 matched with the slide rod 1, and the movable seat 31 is sleeved on the slide rod 1 and is in sliding connection with the slide rod 1 through the jaw 32. The jaw 32 is arranged to enable the movable seat 31 to be matched and connected with the slide rod 1, thereby ensuring the stable installation of the movable seat 31 on the slide rod 1 and preventing loosening or deviation of the movable seat 31 due to vibration or external force during use. Meanwhile, the cooperation between the jaw 32 and the slide rod 1 allows the movable seat 31 to smoothly slide on the slide rod 1, and such a sliding connection enables the user to easily adjust the position of the movable seat 31 as needed to adapt to workpieces of different sizes or shapes.

[0033] In the embodiment, the length of the second lead screw 35 is greater than that of the first lead screw 6. This design enables the second pressing foot 34 on the second lead screw 35 to move to a farther position, thereby expanding the clamping range of the F clamp. Meanwhile, the longer second lead screw 35 provides the user with a larger adjustment space, so that the user can make more flexible clamping adjustments according to the size and shape of the workpiece, which helps to improve the accuracy and stability of clamping.

[0034] In the embodiment, the slide rod 1 is fixedly provided with a stop pin 4 near the right end. The stop pin 4 is arranged to limit the movement or falling of the components. When the movable arm 33 moves to the rightmost end of the slide rod 1, the stop pin 4 prevents it from continuing to move, thereby preventing the movable arm 33 from falling off the slide rod 1 due to excessive movement.

[0035] The working principle of the multi-head F clamp is as follows:

[0036] The multi-head mechanism 3 can be used on the ratchet F clamp or the ordinary F clamp.

[0037] If the assembled in ratchet F clamp, in use, push the movable clamp foot 2 to reach the appropriate opening amount, then hold the handle on the ratchet F clamp, clamp the workpiece, adjust the movable seat 31, make the movable arm 33 reach the appropriate opening amount, screw the second cross arm 36 on the movable arm 33 to adjust the position of the second lead screw 35, clamp other workpieces that need to be connected through the second pressure foot 34 on it, realize the effect of clamping multiple workpieces at the same time with one tool.

[0038] If the assembled in ordinary F clamp, in use, push the movable clamp foot 2 to reach the appropriate opening amount, then screw the first cross arm 7 on the movable clamp foot 2 to adjust the position of the first lead screw 6, clamp the workpiece, adjust the movable seat 31, make the movable arm 33 reach the appropriate opening amount, screw the second cross arm 36 on the movable arm 33 to adjust the position of the second lead screw 35, clamp other workpieces that need to be connected through the second pressure foot 34 on it, realize the effect of clamping multiple workpieces at the same time with one tool.
