[0035] AsFigures 1-5 As shown in the drawings, the vise clamp comprises a fixed clamp body 1, a movable clamp body 2 arranged opposite to the fixed clamp body 1, and a driving mechanism 3 capable of driving the movable clamp body 2 to move close to or away from the fixed clamp body 1, a clamping space is formed between the fixed clamp body 1 and the movable clamp body 2, an object can be installed in the clamping space, and the object is clamped by driving the movable clamp body 2 to move close to the fixed clamp body 1 by the driving mechanism 3, thereby ensuring the stability of the clamping of the object.

[0036] It can be understood that the fixed clamp body 1 and the movable clamp body 2 are cuboid structures, which can increase the contact area with the object and ensure the stability of the clamping of the object.

[0037] The vise clamp further comprises a base 4, the fixed clamp body 1 is fixed on the base 4 to form an L-shaped structure, and the movable clamp body 2 is movable along the base 4.

[0038] In this embodiment of the present application, the base 4 and the fixed clamp body 1 are of an integrated structure, which are integrally formed by casting, and the integrated structure has higher strength and better stability, so the integrated structure is preferred.

[0039] In other embodiments of the present application, the base 4 and the fixed clamp body 1 are formed by separate casting and then fixed together by screwing or welding. It should be understood by those skilled in the art that the base 4 and the fixed clamp body 1 are integrally cast or separately cast and then fixed, which is not limited in the present application.

[0040] Further, the driving mechanism 3 comprises a driving rod 301, an external thread 302 arranged on the driving rod 301, and a threaded fitting 303 arranged in the movable clamp body 2 and capable of fitting with the external thread 302, one end of the driving rod 301 with the external thread 302 is rotatably arranged in the base 4 and protrudes from the base 4 to be connected with the threaded fitting 303.

[0041] The external thread 302 accounts for 1 / 3-2 / 3 of the total length of the driving rod 301, and specifically, the external thread 302 accounts for 1 / 2 of the total length of the driving rod 301.

[0042] In this embodiment of the present application, the threaded fitting 303 is a threaded hole formed in the movable clamp body 2 and capable of fitting with the external thread 302.

[0043] In other embodiments of the present application, the threaded fitting 303 can also be a nut fixed on the movable clamp body 2 and capable of fitting with the external thread 302. It should be understood by those skilled in the art that the threaded fitting 303 adopts a threaded hole or a nut, which is not limited in the present application.

[0044] It can be understood that in order to facilitate the rotation of the driving rod 301, a through hole with a diameter greater than or equal to that of the driving rod 301 needs to be formed in the base 4 for the installation of the driving rod 301.

[0045] Based on the above technical means: since the driving rod 301 can only make a rotating motion, the threaded fitting 303 is matched with the external thread 302, so when the driving rod 301 is rotated, the movable clamping body 2 can make a transverse motion, according to the rotating direction of the driving rod 301, the movable clamping body 2 is made to approach or move away from the fixed clamping body 1, and then the object is clamped, different sizes of objects can be matched, and the applicability is strong.

[0046] Further, the fixed clamping body 1, the movable clamping body 2 and the inner surface of the base 4 are all provided with the anti-skid mechanism 5.

[0047] In this embodiment of the application, the anti-skid mechanism 5 comprises anti-skid pads 501 arranged on the inner surfaces of the fixed clamping body 1, the movable clamping body 2 and the base 4 and a plurality of anti-skid protrusions 502 arranged on the anti-skid pads 501.

[0048] It is worth mentioning that the anti-skid pads 501 and the anti-skid protrusions 502 are made of soft rubber material, the anti-skid protrusions 502 improve the clamping force on the object, and at the same time can reduce the marks left on the surface of the object, and can effectively protect the object.

[0049] According to another embodiment of the application, the anti-skid mechanism 5 comprises concave-convex textures arranged on the inner surfaces of the fixed clamping body 1, the movable clamping body 2 and the base 4, and the concave-convex textures can make the inner surfaces of the fixed clamping body 1, the movable clamping body 2 and the base 4 become uneven, and then increase the friction force on the object.

[0050] It can be understood that the base 4 is provided with an open slot 401, the movable clamping body 2 is provided with a guide seat 6 with a width smaller than the open slot 401, the threaded fitting 303 is arranged on the guide seat 6, the guide seat 6 and the open slot 401 are matched to play a guiding role, and at the same time, since the width of the guide seat 6 is smaller than the open slot 401, when the movable clamping body 2 moves, the side wall of the open slot 401 will not interfere with the movable clamping body 2.

[0051] In this embodiment of the application, the guide seat 6 and the movable clamping body 2 are of an integrated structure, and are integrally cast into shape, so the integrated structure has higher strength and better stability, and therefore the integrated structure is preferred.

[0052] In other embodiments of the application, the guide seat 6 and the movable clamping body 2 are separately cast, and then are fixed together through a screwing or welding process. It should be understood by those skilled in the art that the guide seat 6 and the movable clamping body 2 are integrally cast or are separately cast and then fixed, which is not limited in the application.

[0053] Furthermore, a vise clamp also includes two guide rods 7, which are equally spaced on both sides of the drive rod 301. One end of the guide rod 7 is fixed to the guide seat 6, and the other end is located in the base 4. The guide rod 7 plays a guiding role, so that the guide seat 6 and the moving clamp 2 can move laterally when the drive rod 301 is rotated.

[0054] It is understandable that both the guide seat 6 and the base 4 are provided with through holes for connecting the guide rod 7, and the diameter of the through hole on the base 4 is greater than or equal to that of the guide rod 7, which facilitates the movement of the guide rod 7.

[0055] In this embodiment of the invention, the guide rod 7 is fixedly connected to the guide seat 6 by a threaded connection, that is, one end of the guide rod 7 is provided with a thread, and the through hole of the guide seat 6 is a threaded hole 402. The threaded connection has the advantages of simple connection and easy disassembly, so the threaded connection is preferred.

[0056] In other embodiments of the present invention, the guide rod 7 may be welded and fixedly connected to the guide seat 6. Those skilled in the art should understand that the use of a threaded or welded connection for the guide rod 7 is not a limitation of this application.

[0057] Furthermore, a vise clamp also includes two elastic elements 8, which are respectively sleeved on the guide rod 7. The elastic elements 8 play a role in elastic reset. Since the diameters of the drive rod 301 and the guide rod 7 are equal to or smaller than the through hole of the base 4, if tilting occurs, the drive rod 301, the guide rod 7, the fixed clamp body 1, and the guide seat 6 will move on their own. Therefore, it is necessary to restrict the drive rod 301, the guide rod 7, the fixed clamp body 1, and the guide seat 6.

[0058] In this embodiment of the invention, the elastic element 8 is a spring, such as... Figure 3 As shown, when the vise tilts to the left, one end of the spring abuts against the side wall of the base 4, and the other end abuts against the side wall of the guide seat 6, preventing the guide seat 6 from moving to the left, and thus preventing the drive rod 301, guide rod 7, and fixed clamp 1 from moving to the left. Because the spring has a certain deformation, it compresses when the drive rod 301 is rotated to clamp the object, and returns to its original position when the drive rod 301 is rotated back, without affecting its normal use.

[0059] Furthermore, the drive mechanism 3 also includes a handle 304 and an anti-detachment component 305. The handle 304 is located at one end of the drive rod 301, and the anti-detachment component 305 is located at the other end of the drive rod 301 and is located outside the movable clamp 2.

[0060] In the embodiment of the present application, the knob 304 is made of plastic and is adhered to one end of the driving rod 301, the knob 304 is in the shape of plum blossom, the knob 304 is convenient for the user to rotate the driving rod 301, and the knob 304 can also limit the driving rod 301, the guide rod 7, the fixed clamp body 1 and the guide seat 6 when the vice clamps are inclined towards the end.

[0061] In the embodiment of the present application, the diameter of the anti-disengagement piece 305 is greater than that of the threaded adapter 303, so that the driving rod 301 and the guide seat 6 can be prevented from being separated.

[0062] In the embodiment of the present application, the anti-disengagement piece 305 is a bolt, and a bolt hole adapted to the bolt is formed in the driving rod 301, so that the anti-disengagement piece 305 is detachably connected to the driving rod 301.

[0063] Further, two threaded holes 402 with different diameters are formed in the base 4, so that the vice clamps can be adapted to different supports, for example, tripods and the like.

[0064] The basic principle and main features of the present application and the advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, the above embodiments and the description in the specification are only to illustrate the principle of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
