It is characterized in that a transmission mechanism 5 is arranged on the working platform 1, the fixed block 3, and the movable block 4;

[0032] The transmission mechanism 5 includes a transmission unit and a limiting unit;

[0033] The limiting unit is used to provide a limit for the clamping of the movable block 4 and the material;

[0034] The transmission unit is used to provide a limit for the clamping of the fixed block 3 and the material;

[0035] The transmission unit includes a first clamping block 501, a first movable rod 502, a rotating block 503, a first abutting block 504, and a second abutting block 505;

[0036] The first clamping block 501 is fixed to the end of the first movable rod 502, and the first clamping block 501 is used for clamping the material;

[0037] The first movable rod 502 is vertically slidably installed inside the movable block 4 and extends outside the movable block 4, and the first movable rod 502 is used to drive the first clamping block 501 to move;

[0038] The rotating block 503 is rotatably installed on the inner wall of the movable block 4 and is located below the protruding part on one side of the first movable rod 502, and the rotating block 503 is used to provide support for the movement of the first movable rod 502;

[0039] The first abutting block 504 is fixed to the inner wall of the working platform 1, and the first abutting block 504 is used to provide a thrust force for the rotating block 503;

[0040] The second abutting block 505 is fixed to the outer wall of the fixed block 3, and the second abutting block 505 is used to provide a thrust force for the rotating block 503;

[0041] The transmission unit further includes a second clamping block 506, a second movable rod 507, a spring 508, and a transmission rod 509;

[0042] The second clamping block 506 is fixed to the top of the second movable rod 507, and the second clamping block 506 is used for clamping the material;

[0043] The second movable rod 507 is vertically slidably installed inside the fixed block 3, and the second movable rod 507 is used to drive the second clamping block 506 to move synchronously;

[0044] The two ends of the spring 508 are respectively clamped to the inner wall of the fixed block 3 and the outer wall of the second movable rod 507, and the spring 508 is used to always give an upward thrust force to the second clamping block 506;

[0045] The transmission rod 509 is fixed to the bottom end of the second movable rod 507, and the transmission rod 509 is used to transmit the extrusion thrust force from the movable block 4.

[0046] In this embodiment: When using this device, by starting the cylinder 2, the cylinder 2 works to pull the movable block 4 to move reciprocally. During the process of the movable block 4 moving towards the fixed block 3, the inclined surface at the end of the movable block 4 gives a downward pressure to the transmission rod 509. The transmission rod 509 moves downward under the force. The downward-moving transmission rod 509 synchronously drives the second movable rod 507 to move downward and gives an extrusion force to the second movable rod 507. The movement of the second movable rod 507 will synchronously drive the second clamping block 506 to move, so that the second clamping block 506 no longer clamps and positions the material, and the movable block 4 pulls the material to move along the inner side of the fixed block 3. When the movable block 4 gradually approaches the fixed block 3, the second abutting block 505 fixed on the outer wall of the fixed block 3 will contact the upper half of the rotating block 503 and give a thrust to the rotating block 503 to make it rotate. The rotating rotating block 503 no longer provides support for the first movable rod 502, so that the first movable rod 502 and the first clamping block 501 move downward under the action of gravity and no longer clamp the material. Then when the movable block 4 is reset under the influence of the cylinder 2, the first clamping block 501 no longer pulls the material to move. After the movable block 4 returns to its original position, the first abutting block 504 contacts the rotating block 503, and through the rotating block 503, a thrust is given to the protruding part on the outer wall of the first movable rod 502, so that the first movable rod 502 and the first clamping block 501 move upward to clamp the material again. This process is repeated, reducing the starting unit for intermittently clamping the material by controlling the fixed block 3 and the movable block 4, facilitating the automatic clamping and positioning of the material, and further reducing the cost.

[0047] Please refer specifically to Figures 1 - 3 , one end of the movable block 4 close to the transmission rod 509 is in an inclined state. One side of the movable block 4 is fixedly connected to the output end of the cylinder 2. The outer wall of the second movable rod 507 is in an overall "cross" shape. A chute for the vertical movement of the second movable rod 507 is formed on the inner wall of the fixed block 3. The first abutting block 504 and the second abutting block 505 are symmetrically distributed, and both the first abutting block 504 and the second abutting block 505 are higher than the axis of the rotating block 503. The outer wall of the rotating block 503 is in an overall oval shape. A rotating groove for the rotation of the rotating block 503 is formed on the inner wall of the movable block 4.

[0048] In this embodiment: Through this structure, during the process of the movable block 4 moving towards the fixed block 3, the inclined end face of the movable block 4 gives a thrust to the transmission rod 509 to drive the second clamping block 506 to move downward to release the clamping of the material. When the movable block 4 is reset, the second clamping block 506 on the fixed block 3 will also be reset under the action of the spring 508 to clamp and position the material here.

[0049] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
