Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, an embodiment of the present invention provides a parallel clamp, including a clamp holder 1, a driving mechanism 2 and a clamp 3, wherein the clamp holder 1 is provided with a sliding groove 11; clamping piece 3 comprises a left clamping piece 31 and a right clamping piece 32, and left clamping piece 31 and right clamping piece 32 are arranged in a left-right mirror image mode relative to the center of clamping base 1; the driving mechanism 2 comprises a driving block 21 and a driving assembly 22, the driving block 21 is slidably connected in the sliding groove 11, the driving assembly 22 comprises a first driving assembly 221 and a second driving assembly 222, at least two groups of first driving assemblies 221 are arranged on the front side of the clamping seat 1, the two groups of first driving assemblies 221 are arranged in parallel, one group comprises two first driving pieces 2210, the first ends of the two first driving pieces 2210 are hinged with the driving block 21, and the second ends of the two first driving pieces 2210 are hinged with the left clamping piece 31 and the right clamping piece 32 respectively; the second driving assembly 222 at the front side of the holder 1 at least comprises two second driving members 2220, the first ends of the two second driving members 2220 are hinged to the holder 1, the second ends are hinged to the first driving members 2210 respectively, and the driving assembly 22 at the rear side of the holder 1 is arranged in a front-back mirror image with respect to the center of the holder 1 and the driving assembly at the front side of the holder 1;

the driving block 21 slides, so that the first driving assembly 221 and the second driving assembly 222 can drive the left clamping member 31 and the right clamping member 32 to move close to or away from each other together, so as to meet the requirement of clamping the object.

According to the above solution, in use, the driving block 21 slides along the sliding slot 11 and gradually approaches the bottom end of the sliding slot 11, so that the first driving member 2210 and the second driving member 2220 jointly drive the left clamping member 31 and the right clamping member 32 to move away from each other, so that an object can be placed between the left clamping member 31 and the right clamping member 32, and then the driving block 21 is driven to move away from the bottom end of the sliding slot 11, so that the first driving member 2210 and the second driving member 2220 jointly drive the left clamping member 31 and the right clamping member 32 to approach each other, so as to clamp a plurality of objects with the same shape, so as to meet the operation requirement, avoid the situation that a plurality of clamping operations are required when a plurality of objects are operated, and improve the operation efficiency; when the operation is completed and the object needs to be removed, the driving block 21 is driven so that the first driving member 2210 and the second driving member 2220 jointly drive the left clamping member 31 and the right clamping member 32 away from each other, thereby removing the object.

Further, in order to make the sliding of the driving block 21 more stable and reliable, the object can be gripped more firmly. The left side and the right side of the driving block 21 are provided with limiting bosses 210, the corresponding positions of the sliding grooves 11 are provided with limiting grooves 110 matched with the limiting bosses 210, and the limiting bosses 210 extend into the limiting grooves 110 and can move along the directions of the limiting grooves 110. When the driving block 21 slides, the limiting boss 210 extends into the limiting groove 110, so that the phenomenon that the driving block 21 shakes back and forth is avoided.

Further, in order to more conveniently drive the driving block 21 to slide in the sliding slot 11, the parallel clamp further comprises a screw rod 4, the screw rod 4 is rotatably connected to the clamp holder 1 and is in driving connection with the driving block 21, and the driving block 21 can slide in the sliding slot 11 by rotating the screw rod 4. The screw rod 4 can be rotated by a motor, so that an automatic effect is achieved; the screw 4 can also be rotated manually. In general, the particular drive scheme is selected based on the particular application.

Further, in order to better realize the sliding of the driving block 21, the clamping requirement of the object is met. The parallel clamp further comprises a connecting nut 5, the connecting nut 5 is connected with the screw rod 4 in a matched mode, the connecting nut 5 is fixedly arranged on the driving block 21, and the screw rod 4 is rotated to enable the connecting nut 5 to drive the driving block 21 to slide in the sliding groove 11.

Specifically, the coupling nut 5 may be fixed to the driving block 21 in an interference fit manner. Meanwhile, the production cost and the replacement cost of the driving block 21 can be reduced by arranging the connecting nut 5 compared with directly arranging the thread on the driving block 21. The driving block 21 is driven to slide by the matching connection of the screw rod 4 and the connecting nut 5, so that the left clamping piece 31 and the right clamping piece 32 are driven to approach or separate from each other, the stress on the thread is large, and the clamping requirement can be met by using a material with higher price and better performance. Therefore, if directly set up the screw thread on drive block 21, just need to change the material of whole drive block 21 into the performance better to improved the manufacturing cost of drive block 21, simultaneously, when drive block 21 part screw thread damaged, still need be better drive block 21 is whole, improved replacement cost. However, if the connection nut 5 is used, the overall size of the connection nut 5 is small, the production cost is low, and meanwhile, when the thread of the connection nut 5 is damaged, only the connection nut needs to be replaced, and the replacement cost is also low.

Further, in order to ensure that the clamping of the object is more reliable, the object is prevented from slipping. The parallel clamp further comprises two anti-slip pads 6, wherein the two anti-slip pads 6 are fixedly arranged on two side walls of the left clamping piece 31 and the right clamping piece 32 which are close to each other respectively, so that the object can be clamped conveniently. In the present embodiment, the non-slip mat 6 is preferably fixedly adhered to the left and right clamping
