Extensible stable clamping device

An extensible stable clamping device, comprising:

• a chuck subassembly capable of being closed and opened, wherein the chuck subassembly comprises:
• two clamping jaw bodies used for clamping an object, and a clamping jaw head arranged at a top of each clamping jaw body and capable of contacting each other to maintain the stability of the extensible stable clamping device;
• the two clamping jaw bodies are curved towards the inner sides and are symmetrically disposed;
• after the two clamping jaw bodies are closed, a clamping gap is formed between the clamping jaw bodies;
• the clamping gap is capable of accommodating a clamped object;
• each clamping jaw head is located at the top of the clamping jaw body and extends a distance in a direction where the clamping jaw body extends out to form a plate shape;
• and after the two clamping jaw bodies are closed, the two clamping jaw heads are attached to each other to improve the clamping stability of the extensible stable clamping device;
• wherein the extensible stable clamping device further comprises a foldable connecting rod subassembly, a handle mounted at one end of the connecting rod subassembly, and a drive subassembly mounted at the other end of the connecting rod subassembly;
• the chuck subassembly is mounted on the drive subassembly;
• the drive subassembly is driven to drive the chuck subassembly to be closed and opened, thus completing picking and placement of the object;
• the driving subassembly comprises a drive trigger mounted on the handle, a drive connecting rod which is in drive connection with the drive trigger, an actuator mounted on the drive connecting rod, a drive body used for mounting the actuator, and driving support rods and a driven support rods;
• one end of each driving support rod and one end of each driven support rod are rotatably mounted on the drive body, and the other end of the driving support rod and the driven support rod are rotatably connected to the chuck subassembly;
• the driving support rods are further in drive connection with the actuator;
• the drive trigger is triggered towards the handle;
• the drive trigger drives the drive connecting rod;
• the drive connecting rod drives the actuator to move towards the handle;
• the actuator drives the driving support rods to rotate towards the inner side;
• the driving support rods drives, through the chuck subassembly, the driven support rods to rotate towards the inner side, thus closing the chuck subassembly;
• the drive trigger is triggered away from the handle;
• the drive trigger drives the drive connecting rod;
• the drive connecting rod drives the actuator to move away from the handle;
• the actuator drives the driving support rods to rotate towards the outer side;
• the driving support rods drive, through the chuck subassembly, the driven support rods to rotate towards the outer side, thus opening the chuck subassembly.
