[0021] The mobile clamping device 6 includes a mobile frame 61, and an extrusion groove 62 is opened on the side of the mobile frame 61 close to the supporting extrusion device 8. A placement groove 64 is opened on the side of the mobile frame 61, and a mobile clamping plate 65 is slidably arranged in the placement groove 64. A screw rod 63 is penetrated and threadedly provided on the side of the mobile frame 61, and the screw rod 63 is connected to the mobile clamping plate 65. The mobile frame 61 is slidably arranged in the sliding hole 5, and the mobile clamping plate 65 is set in a circular shape. The mobile frame 61 is connected to the guide connecting device 7, and the extrusion groove 62 is inclined. The supporting extrusion device 8 is slidably arranged in the extrusion groove 62.

[0022] A screw rod 63 and a movable clamping plate 65 are used. When the screw rod 63 rotates, the movable clamping plate 65 can be controlled to move closer to or farther from the movable frame 61, so as to adjust the distance between the movable clamping plates 65 on the front and rear sides. The movable clamping plate 65 is used to clamp and position the metal. A movable frame 61 and a sliding hole 5 are used. The sliding hole 5 guides the movable frame 61 to prevent the movable frame 61 from rotating during movement.

[0023] A pad 3 is provided inside the support frame 1 , and the pad 3 is located at the lower side of the placement plate 2 . Four mounting feet 4 are connected to the lower side of the support frame 1 .

[0024] The pad 3 is used to support and limit the lower limit position of the placement plate 2 during its movement;

[0025] The guide connection device 7 includes a guide sleeve 71, which is arranged on the side of the support frame 1. A guide rod 72 is slidably arranged in the guide sleeve 71, and the guide rod 72 is connected to the movable frame 61. A first elastic component 73 is arranged on the outer sleeve of the guide rod 72, and the first elastic component 73 is connected to the guide sleeve 71.

[0026] The guide sleeve 71 is used to limit and guide the guide rod 72, so that the movable frame 61 performs a linear motion in the horizontal direction when a force is applied thereto;

[0027] The supporting extrusion device 8 includes two sliding sleeves 81 , the sides of the sliding sleeves 81 are connected with fixed rods 82 , the fixed rods 82 are connected in the supporting frame 1 , the sliding sleeves 81 are slidably connected with sliding rods 83 , and the top ends of the sliding rods 83 are connected to the placement plate 2 .

[0028] The sliding sleeve 81 is used to guide the vertical movement of the sliding rod 83 and the placement plate 2, so that the placement plate 2 and the extrusion rod 85 can move smoothly and stably in a straight line;

[0029] The outer sleeve of the slide rod 83 is provided with a second elastic component 84 connected to the placement plate 2 and the slide sleeve 81 , and the bottom ends of the two slide rods 83 are connected to an extrusion rod 85 slidably arranged in the extrusion groove 62 .

[0030] The extrusion rod 85 and the extrusion groove 62 are used in cooperation. The movement of the extrusion rod 85 along the inclined extrusion groove 62 will control the movable frame 61 to move horizontally. The second elastic component 84 is used to buffer the downward movement of the placement plate 2. At the same time, after the metal is separated from the placement plate 2, the placement plate 2 is controlled to reset upward.

[0031] The working principle of the utility model is:

[0032] When it is necessary to clamp the metal, first control the rotation of the screw rod 63 according to the size of the metal. When the screw rod 63 rotates, control the movement of the movable clamping plate 65. When the distance between the movable clamping plate 65 and the movable frame 61 is appropriate, stop rotating the screw rod 63, and place the metal directly on the placement plate 2. The metal extrusion placement plate 2, the slide bar 83 and the extrusion rod 85 move downward. During the movement of the extrusion rod 85, it slides in the extrusion groove 62 to control the extrusion groove 62 and the movable frame 61 to move close to the metal. When the placement plate 2 contacts the pad 3 and the four movable clamping plates 65 are all in contact with the metal, the clamping and positioning of the metal is completed.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
