First elastic member 63 acts on base 61 and clamp 62 to bring a first end of clamp 62 into abutment against the wall of hole of product 100 and lock product 100.
Specifically, as shown in fig. 9 and 10, the first elastic member 63 is a spring, and is installed in the second installation groove 6121, one end of the spring is sleeved on the portion of the positioning screw 6122 extending into the second installation groove 6121, and the other end of the spring abuts against the second end of the rod 621. In this embodiment, when the operating portion 622 is pressed by an external force, the second end of the rod 621 rotates toward the side where the positioning screw 6122 is located, the first elastic member 63 compresses to store energy, and the abutting protrusion 6211 on the first end of the rod 621 retracts into the first opening 6113, so that the product 100 can be easily sleeved on the protrusion 6111 from top to bottom; when the product 100 is put in place, the pressing force on the operating portion 622 is released, the first elastic member 63 releases energy, the energy is released to the place, the second end of the rod portion 621 rotates away from the side of the positioning screw 6122, the operating portion 622 protrudes out of the opening of the second mounting groove 6121, and the abutting protrusion 6211 on the first end of the rod portion 621 protrudes out of the first opening 6113 to abut against the hole wall of the product 100 and lock the product 100.

Preferably, in this embodiment, the distance between the second end of the lever portion 621 and the pivot thereof is greater than the distance between the first end of the lever portion 621 and the pivot thereof, when the first elastic member 63 abuts against the second end of the lever portion 621, the moment arm on the side where the first elastic member 63 is located is longer, and under the same acting force, the moment applied to the lever portion 621 by the first elastic member 63 is larger, so as to facilitate increasing the abutting force of the abutting protrusion 6211 on the product 100. It should be noted that the installation position of the first elastic element 63 in the base 611 is not limited, and it only needs to satisfy the function of driving the rod 621 to rotate until the abutting protrusion 6211 keeps abutting against the hole wall of the product 100.
In this embodiment, the first end of the stem 621 can also reliably lock the product 100 without the abutment protrusion 6211, if the abutment protrusion 6211 is provided, and in order to achieve a better locking effect, the product 100 may be provided with a concave point on the hole wall thereof for the abutment protrusion 6211 to be inserted into during the molding process.

the frame is provided with a guide surface and a guide surface; the guide surface is located before the stopper arm in the conveying direction of the conveyor belt; the guide surface is positioned behind the limiting arm in the conveying direction of the conveying belt, and both the guide surface and the guide surface extend along the fourth straight line section;
the tool is provided with a polygonal abutting plate; the abutting plate is coaxially and fixedly connected with the base, and abutting parts are arranged at all corners of the surface of the abutting plate; before the tool enters the steering unit, the first edge of the abutting plate is abutted to the guide surface; when the tool passes through the steering unit, the limiting arm abuts against the abutting part so that the abutting plate rotates around the axis of the base and rotates until a second edge adjacent to the first edge abuts against the guide surface, and the limiting arm rotates until the limiting arm abuts against the guide surface; when the abutting plate rotates in place, the abutting part is separated from the limiting arm, and the fourth elastic piece pushes the sliding connection block to reset.
9. The rotary conveyor assembly according to claim 1, wherein said first tensioning unit comprises a first drive sprocket, a first drive sprocket shaft, a first driven sprocket and a first driven sprocket shaft; the first driving chain wheel shaft and the first driven chain wheel shaft are both vertically arranged and are both mounted on the adjusting seat; the first driving chain wheel and the first driven chain wheel are respectively and rotationally connected to the first driving chain wheel shaft and the first driven chain wheel shaft;
the second tensioning unit comprises a second driving chain wheel, a second driving chain wheel shaft, a second driven chain wheel and a second driven chain wheel shaft; the second driving chain wheel shaft and the second driven chain wheel shaft are both vertically arranged and are both mounted on the rack; the second driving chain wheel and the second driven chain wheel are respectively and rotationally connected to the second driving chain wheel shaft and the second driven chain wheel shaft;
the conveyer belt is a chain belt, and is tensioned among the first driving chain wheel, the first driven chain wheel, the second driving chain wheel and the second driven chain wheel.
10.
