The spring shaft 205 is fixed on the upper surface of the conveying box 3, the bottom of the cylinder body 201 is provided with a straight slot 202, the rotating track of the lever 1 is a circular arc, so the bottom of the cylinder is provided with a straight slot 202 for the displacement of the cylinder body 201.

[0035] The triangular mechanism 4 includes two triangular steel plates rotatably connected to the side walls of the conveying box 3. In order to enhance the connection strength and make the two triangular steel plates rotate synchronously, a connecting plate 402 is arranged between the two triangular steel plates. In order to enhance the stability of the triangular steel plate 4, a reinforcing plate is integrally formed on the inclined edge of the triangular steel plate, as shown in the accompanying Figure 9 The original triangular steel plate and the reinforcing plate are combined to form a rectangular steel plate. In order to transmit force more stably, the bottom of the connecting plate is provided with a driving plate 403, and the rectangular steel plate, the connecting plate 402 and the driving plate 403 combine to form the triangular mechanism 4 of the embodiment.

Drive plate 403 serves as the input end of the driving force. When external force acts on drive plate 403 at the bottom of triangular mechanism 4, the force is transmitted through triangular mechanism 4 to lever 1, thereby lifting holding block 5.

[0036] A shaft is provided at the upper left end of the material transfer box 3. The left end of the lever 1 is hinged to the shaft at the left end of the material transfer box 3. The holding block 5 is rotatably connected to the right end of the lever 1. The lower surface of the holding block 5 is provided with evenly distributed raised anti-slip structures.

[0037] The specific implementation is as follows:

[0038] The working principle of the whole structure is as shown in the attached Figure 3 As shown, this device is installed on a turntable conveyor mechanism. The material conveyor belt transports the block 6 to be transported to the material receiving position. A reciprocating push rod is provided on the material conveyor belt frame. When the turntable conveyor mechanism rotates this device to the material receiving position, the push rod extends and presses against the driving plate 403 of the triangular mechanism 4. The triangular mechanism 4 rotates around the hinge point on the upper right side. The support rod 401 at the left end of the triangular mechanism 4 lifts the lever 1. The lever 1 rotates around the hinge point on the left end of the material transfer box 3, driving the support ear of the spring barrel to move the barrel 201 to the upper left. The right end of the straight notch 202 at the bottom of the barrel 201 presses against the axis of the spring 204. The spring 204 in the spring barrel is compressed to accumulate elastic potential energy. The holding block 5 connected to the right end of the lever 1 also follows the movement of the lever 1 and is lifted up. As shown in the attached figure Figure 7 As shown, when the block 6 is transported from the right end of the material transfer box 3 into the material transfer box 3, the push rod contracts, and the spring 204 in the spring barrel releases the accumulated elastic potential energy. The elastic potential energy acts on the bottom of the cylinder 201 of the spring barrel, and the spring barrel moves to the lower right, and acts on the lever 1 through the support ears on both sides, so that the lever 1 rotates clockwise around the left end hinge point, driving the holding block 5 at the right end of the lever 1 to move downward, and the evenly distributed protrusions on the lower surface of the holding block 5 are parallel to and tightly fit with the held block 5. The left end of the straight slot 202 at the bottom of the cylinder 201 of the spring barrel rests on the axis of the spring 204. After the holding is completed, the turntable conveying mechanism rotates the device to complete the rotary conveying.
