Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification.

As shown in fig. 1-2, the F-shaped clamp includes a fixed clamp 10, a movable clamp 20 and a guide rod 30, the guide rod 30 is inserted into the fixed clamp 10 and the movable clamp 20, the fixed clamp is fixed on the guide rod during operation, the movable clamp can move relative to the guide rod by holding the

handles

21 and 22 on the movable clamp, and the distance between the movable clamp and the fixed clamp is changed to make the movable clamp and the fixed clamp approach each other as in the fixed clamp shown in fig. 3 to clamp an object or to make the movable clamp and the fixed clamp move away from each other as in the fixed clamp shown in fig. 6 to support an object.

To switch the state between fig. 3 and 6, the stationary clamp body 10 is detachable from one end of the guide bar 30 and is mounted at the other end thereof.

Specifically, the edge of the guide bar 30 is provided with a fixing groove 31, the fixing clip body 10 is provided with an accommodating part 11, one side of the fixing clip body is provided with a cover plate 12, and the accommodating part 11 is covered by the cover plate 12.

In either of the assembled states shown in fig. 3 and 6, the fixing groove 31 of the guide bar 30 is located in the accommodating portion 11, the movable control member 13 is disposed in the accommodating portion 11, and the accommodating portion 11 guides the control member 13, and for this purpose, the accommodating portion extends in the moving direction of the control member, and the accommodating portion conforms to the shape of the control member so that the control member can be moved by the accommodating portion.

The control element 13 is provided with a securing member 14, which securing member 14 is preferably a bayonet catch, preferably a metal pin, made in one piece with the control element.

The control element 13 is acted on by an elastic element 15, the elastic element 15 is a helical compression spring, two ends of the helical compression spring are respectively supported on the control element and the fixed clamp body, and the control element elastically moves in the moving direction of the control element by the aid of the elastic force of the elastic element.

The control element 13 is connected with a control slide button 16 positioned on one side of the fixed clamp body, the fixed clamp body 10 is provided with a through hole 17 communicated with the accommodating part, the control slide button 16 penetrates through the through hole 17 to be connected with the control element 13, and the control element is driven to move through the control slide button.

When the control element is driven to move by the control slide button, the fixing piece moves along with the control slide button, so that the fixing piece 14 is jointed with the fixed groove 31 as shown in fig. 4 and 7 or is separated from the fixed groove as shown in fig. 5 and 8, the fixed clamp body is fixedly positioned with the guide rod when the fixing piece 14 is jointed with the fixed groove 31 and is used for being matched with the movable clamp body to clamp an object or support the object, and the fixed clamp body can be disassembled from the guide rod when the fixing piece is separated from the fixed groove.

When the guide rod is inserted into the fixing clip body to be in the state shown in fig. 3-5, the end of the guide rod overcomes the elastic force of the elastic element 15 to force the control element 13 to carry the fixing element 14 to move out of position, and when the fixing element 14 corresponds to the fixing groove 31, the elastic force of the elastic element forces the fixing element 14 to be clamped into the fixing groove 31 to realize assembly and automatic locking.

As shown in FIG. 5, the moving direction of the control element 13 is kept at an angle α of 0-180 degrees with the length direction of the guide rod 30, and particularly, the angle is 45 degrees and 45 degrees, which is particularly suitable for automatically installing the fixing clip body on the guide rod.

When the fixing clip body needs to be disassembled, the control element 13 is driven to move by the control slide button 16, the fixing piece 14 moves along with the control slide button and is separated from the fixing groove 31 as shown in fig. 5 and 8, and the fixing clip body 10 can be detached from the guide rod 30. When the fixed clamp body is required to be installed at the other end of the guide rod, the control element can be driven to move by the control slide button, the fixing piece moves along with the control slide button and gives the position, the guide rod can be arranged on the fixed clamp body in a penetrating mode, when the fixing groove corresponds to the fixing piece, the control slide button is released, and the control element is clamped into the fixing groove under the elastic action of the elastic element to achieve assembly of the fixed clamp body and the guide rod. In addition, when the guide bar is assembled to the state shown in fig. 3-5, the guide bar corresponding to the accommodating portion is inserted into the fixing clip body, so that the fixing clip body and the guide bar can be automatically assembled and locked as described above.
