As shown in fig. 1 to 6, a plate chain unit includes a clamp assembly for clamping a work conveyed on the plate chain unit, the clamp assembly including a locking seat 10 having a length direction and a clamp body 20 relatively sliding along the length direction of the locking seat 10;

the lower part of the first end of the locking seat 10 in the length direction is obliquely provided with a guide surface 101, and the guide surface 101 is gradually inclined downwards along the direction from the first end to the second end of the locking seat 10 in the length direction; the first end of the locking seat 10 in the length direction and the second end of the locking seat 10 in the length direction are used for distinguishing two ends of the locking seat 10 in the length direction, the clamp assemblies are generally used in pairs when in use, and the guide surfaces 101 are arranged at the far ends of the pair of opposite clamp assemblies;

the clamp body 20 comprises a clamp main shell 201, a clamping middle rod 202 and an elastic resetting piece 203, wherein the clamping middle rod 202 and the elastic resetting piece are vertically arranged in the clamp main shell 201; the clamping middle rod 202 can move up and down in the clamp main shell 201, the upper end of the clamping middle rod 202 extends upwards out of the clamp main shell 201, a clamping piece 204 is arranged on the clamping middle rod 202 of the upwards extending part, a walking part 205 extending out of the clamp main shell 201 is arranged at the lower part of the clamping middle rod 202, the side surface of the walking part 205 is abutted against the guide surface 101, and the elastic resetting part 203 is arranged in the clamp body 20 and is in a force accumulation state and gives a tendency that the clamping middle rod 202 moves upwards relative to the clamp main shell 201; the walking member 205 may be a round bar pile, a strip, a block, a roller, etc. as long as it can contact with the guide surface 101 and slide on the guide surface 101;

when the clamp body 20 moves from the first end to the second end in the length direction of the locking seat 10 under the action of a first external force, the clamp main shell 201 translates relative to the locking seat 10, the walking part 205 moves downwards along the guide surface 101, and meanwhile, because the length of the clamping middle rod 202 is fixed, the clamping middle rod 202 can only overcome the resistance of the reset spring part to move downwards relative to the locking seat 10 under the action of the first external force, so that the clamping piece 204 is driven to press downwards; due to the special design of the clamp body 20 of the guide surface 101, when the clamp body 20 is subjected to a first horizontal external force from the first end to the second end along the length direction of the locking seat 10, the clamping sheet 204 can be pressed downwards when the clamp body 20 is translated integrally; in practical use, the two clamp assemblies are oppositely arranged on two opposite parts of the workpiece, and the first external force is applied simultaneously, so that the two opposite clamps and the upper and lower pressing of the workpiece can be realized, and the effective fixation of the position of the workpiece is realized.
