[0005] To achieve the above object, the utility model provides a multifunctional F-type clamp, comprising:

[0006] A gear rod, one side of which is provided with a gear rack;

[0007] A fixed seat, fixedly mounted on one end of the gear rod, with a first abutment block mounted on the upper end thereof, and the first abutment block is rotatably mounted on the mounting end of the fixed seat;

[0008] A movable seat is slidably mounted on the gear rod, a connecting cavity for sliding connection to the gear rod is provided at the bottom of the movable seat, a locking wrench for clamping the rack on the gear rod is provided in the connecting cavity, a mounting block is installed at the upper end of the movable seat, an adjusting screw is installed with an internal thread of the mounting block, a second abutment block is rotatably mounted on one side of the adjusting screw close to the first abutment block, and a holding handle is fixed to the other end of the adjusting screw.

[0009] As a further solution of the utility model, the end of the gear rod is provided with a mounting hole for fixing and connecting to a fixing seat, and the mounting hole is used for installing a fixing bolt.

[0010] As a further solution of the utility model, the gripping handle is made of plastic and is provided with anti-slip patterns.

[0011] As a further solution of the utility model, the locking wrench extends out of the movable seat and is arranged on a side of the movable seat close to the gripping handle.

[0012] Compared with the prior art, the utility model designs a gear rod, a fixed seat and a movable seat, wherein the fixed seat is fixedly mounted on one end of the gear rod, the movable seat is slidably connected to the gear rod, and a locking wrench for clamping the rack on the gear rod is provided in the connecting cavity. By allowing the first abutment block and the second abutment block on the fixed seat and the movable seat to rotate 360°, the clamp can adapt to the clamping surface, thereby solving the problem that the abutment block of the currently used F-type clamp is often fixed when in use, and when the abutment surface changes, the contact area of ​​the abutment block cannot be guaranteed, affecting the clamping stability.

[0016] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0017] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, a multifunctional F-type clamp comprises a gear rod 1, one side of which is provided with a rack 101; a fixed seat 2, fixedly mounted on one end of the gear rod 1, an upper end of which is provided with a first abutment block 3, and the first abutment block 3 is rotatably mounted on the mounting end of the fixed seat 2; a movable seat 4, slidably mounted on the gear rod 1, a connecting cavity for slidingly connecting the gear rod 1 is provided at the bottom of the movable seat 4, a locking wrench 8 for clamping the rack 101 on the gear rod 1 is provided in the connecting cavity, a mounting block 401 is mounted on the upper end of the movable seat 4, an adjusting screw 5 is internally threadedly mounted on the mounting block 401, a second abutment block 6 is rotatably mounted on the side of the adjusting screw 5 close to the first abutment block 3, and a gripping handle 7 is fixed on the other end of the adjusting screw 5;

[0018] In the utility model, the locking wrench 8 can be pulled to drive the movable seat 4 to slide and adjust the position of the movable seat 4. At the same time, when locking, the adjusting screw 5 can be rotated, and the adjusting screw 5 is threadedly transmitted on the mounting block 401 to drive the second abutment block 6 to move close to the first abutment block 3. The second abutment block 6 and the first abutment block 3 are clamped on both sides of the component. At the same time, since the first abutment block 3 and the second abutment block 6 can both rotate 360°, the clamping surface can be adapted.

[0019] like Figure 1 As shown, in the embodiment of the utility model, the end of the gear rod 1 is provided with a mounting hole for fixing and connecting the fixing seat 2, and the mounting hole is used to install a fixing bolt. Of course, other fixing methods can also be used to fix the fixing seat 2.

[0020] like Figure 1 As shown, in the embodiment of the utility model, the gripping handle 7 is made of plastic and is provided with anti-skid patterns to prevent slipping when a person grips the gripping handle 7 and rotates it.

[0021] like Figure 2 As shown, in the embodiment of the utility model, the locking wrench 8 extends out of the movable seat 4 and is arranged on the side of the movable seat 4 close to the holding handle 7. When the operator moves the movable seat 4, the locking wrench 8 can be pressed, and the locking wrench 8 drives the locking frame 9 in the connecting cavity of the movable seat 4 to disengage from the rack 101 on the gear rod 1, thereby unlocking the movable seat 4.

[0022] In summary, the utility model designs a gear rod 1, a fixed seat 2 and a movable seat 4, wherein the fixed seat 2 is fixedly mounted on one end of the gear rod 1, and the movable seat 4 is slidably connected to the gear rod 1, and a locking wrench 8 for clamping the rack 101 on the gear rod 1 is provided in the connecting cavity, and the first abutment block 3 and the second abutment block 6 on the fixed seat 2 and the movable seat 4 can be rotated 360°, so that the clamp can adapt to the clamping surface, thereby solving the problem that the abutment block of the currently used F-type clamp is often fixed when in use, and when the abutment surface changes, the contact area of ​​the abutment block cannot be guaranteed, affecting the clamping stability.

[0023] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
