[0043] The multifunctional portable clamp is mainly used for processing board wood. In other embodiments, the multifunctional portable clamp can also be used for processing other materials such as profiles.

[0044] The invention comprises: a main body 100 , a moving block 200 , a clamping driving structure 300 and a rotating clamp 400 .

[0045] Specifically, in this embodiment, the main body 100 is composed of a base 110 and a lower support 120, and the base 110 and the lower support 120 are fixedly connected by welding. In other embodiments, the main body 100 can also be set as an integrated structure, or the base 110 and the lower support 120 can be fixed by screws. Those skilled in the art can select the composition of the main body 100 according to actual needs.

[0046] The lower support body 120 has a rotating shaft protruding upward.

[0047] The rotating clamp 400 is installed above the lower support body 120, and the rotating clamp 400 is sleeved on the rotating shaft. The rotating clamp 400 is rotatably connected to the rotating shaft. The rotating clamp 400 can rotate around the first axis relative to the main body 100.

[0048] The rotating clamp 400 is provided with a plurality of second clamping surfaces 401 . Specifically, the plurality of second clamping surfaces 401 are arranged equidistantly around the first axis. The second clamping surfaces 401 are the circumferential surfaces of the rotating clamp 400 .

[0049] Specifically, in this embodiment, the number of the second clamping surfaces 401 is set to four. In other embodiments, the number of the second clamping surfaces 401 can also be set to three, five, six, etc. The specific number of the second clamping surfaces 401 can be adjusted by technical personnel in this field according to actual conditions.

[0050] The plurality of second clamping surfaces 401 are respectively provided with a plurality of clamping patterns.

[0051] Specifically, in this embodiment, one of the clamping patterns includes a first clamping groove 410. Specifically, in this embodiment, the number of the first clamping groove 410 is set to one. In other embodiments, the number of the first clamping groove 410 can also be set to two, three, etc. The technicians in this field can adjust the number of the first clamping groove 410 according to actual needs. The first clamping groove 410 can be used to vertically clamp the rod-shaped material.

[0052] Specifically, in this embodiment, another clamping pattern includes a second clamping groove 420. The second clamping surface 401 with the second clamping groove 420 is set as the middle surface, and the two second clamping surfaces 401 adjacent to the middle surface are set as the side surfaces. The notch of the second clamping groove 420 is set at the middle surface, and the two ends of the second clamping groove 420 respectively penetrate the two side surfaces.

[0053] Specifically, in this embodiment, another clamping pattern includes a plurality of crisscross third clamping grooves 430, and the two ends of the third clamping grooves 430 respectively penetrate the two opposite end surfaces of the rotating clamp 400. The clamping pattern is arranged in a pattern of a plurality of crisscross third clamping grooves 430, which can be used to clamp plate-like materials. The third clamping grooves 430 can increase the friction between the clamp and the material to better clamp the material.

[0054] A plurality of clamping lines are provided on the second clamping surface 401 to increase friction force, and can be used to clamp some non-standard boards and woods, and can also be used to clamp regular boards and woods, and has high applicability.

[0055] A rotation positioning assembly is disposed between the main body 100 and the rotation clamp 400 .

[0056] Specifically, the rotation positioning assembly includes: a first slot 440 , a second slot 121 and an insert 500 .

[0057] The first slot 440 is disposed on the rotating clamp 400 . Specifically, the first slot 440 is a circular through slot penetrating the rotating clamp 400 in the up-down direction, and the inner wall of the first slot 440 is a cylindrical surface.

[0058] The second slots 121 are arranged in the main body 100. Specifically, in this embodiment, the number of the second clamping surfaces 401 is consistent with the number of the second slots 121, and the second slots 121 are arranged equidistantly around the first axis. Specifically, the distance from the second slot 121 to the first axis is equal to the distance from the first slot 440 to the first axis.

[0059] Specifically, in this embodiment, the insert 500 is a screw-shaped structure. The insert 500 passes through the first slot 440 and is inserted into the second slot 121 , and the lower end of the insert 500 is threadedly connected to the second slot 121 .

[0060] Specifically, in this embodiment, nuts are fixed to the four corners of the lower end of the lower support body 120. The second slot 121 is set as a threaded hole for the nut. In other embodiments, if the main body 100 is an integrated structure, four threaded holes need to be opened in the main body 100 as the second slot 121.

[0061] The second slot 121 is threadedly connected to the insert 500, which can ensure that the lower end of the insert 500 is threadedly connected to the main body 100, so that the insert 500 is not easily separated from the main body 100 due to accident, thereby ensuring that the rotating clamp 400 is not easily rotated relative to the main body 100 due to accident after being positioned.

[0062] The moving block 200 is slidably connected to the main body 100 , and the moving block 200 can slide relative to the main body 100 along a first direction.

[0063] The moving block 200 is connected to the main body 100 via the clamping driving structure 300 , and the clamping driving structure 300 can drive the moving block 200 to move along the first direction.

[0064] Specifically, in this embodiment, the clamping drive structure 300 is configured as a screw-shaped structure extending in the first direction, and the clamping drive structure 300 is threadedly connected to the main body 100.

In other embodiments, a rotating head for rotation may also be fixed at the end of the clamping drive structure 300.

[0065] The handle may be designed to be detachable from the clamping drive structure 300 so that the handle may be replaced.

[0066] Since the clamping drive structure 300 is threadedly connected to the main body 100, when the staff rotates the clamping drive structure 300, the clamping drive structure 300 will move along the first direction relative to the main body 100, and one end of the clamping drive structure 300 will drive the moving block 200 to move along the first direction relative to the main body 100, so that the moving block 200 is close to or away from the rotating clamp 400, thereby achieving clamping and loosening of the workpiece.

[0067] In other embodiments, the clamping drive structure 300 may also be configured as other drive structures such as a linear motor, and those skilled in the art may select the clamping drive structure 300 according to actual needs.

[0068] The end surface of the moving block 200 away from the clamping driving structure 300 is set as a first clamping surface 201. The first clamping surface 201 is arranged opposite to one of the second clamping surfaces 401, and the first clamping surface 201 and the second clamping surface 401 work together to clamp the material.

[0069] Specifically, in this embodiment, a guide assembly is provided between the main body 100 and the guide block.

[0070] Specifically, the guide assembly includes a guide groove 111 and a guide bar 210 .

[0071] The guide groove 111 is opened in the main body 100. Specifically, the guide groove 111 is set at the lower end of the main body 100. In other embodiments, the guide groove 111 can also be set on one side of the main body 100. Those skilled in the art can adjust the actual position of the guide groove 111 according to actual needs.

[0072] The guide bar 210 is fixed to the moving block 200 . The guide bar 210 is disposed in the guide groove 111 and is slidably connected to the guide groove 111 . The guide bar 210 can slide relatively to the guide groove 111 along a first direction.

[0073] The guide groove 111 and the guide bar 210 may be used to guide the moving block 200 to prevent the moving block 200 from being offset during movement.

[0074] Specifically, in this embodiment, a limiting assembly is provided between the main body 100 and the guide block, and the limiting assembly includes a limiting bar 112 and a limiting groove 220 .

[0075] The limiting strip 112 is disposed on the main body 100, and the limiting groove 220 is disposed on the moving block 200, and the limiting groove 220 extends along the first direction. The limiting strip 112 and the limiting groove 220 are slidably connected along the first direction.

[0076] By providing the limiting strip 112 and the limiting groove 220 , the moving block 200 can be limited to prevent the moving block 200 from accidentally separating from the main body 100 during the movement along the first direction.
