The base 161 is adapted to rotate around a vertical axis relative to the conveyor belt 15, and includes a chuck 1611 and a connecting rod 1612, which are both cylindrical structures.

As shown in fig. 8 and 9, the chuck 1611 is formed by coaxially forming three sections of cylinders with diameters increasing from top to bottom, wherein the cylinder at the uppermost end forms a convex portion 16111 for matching and sleeving products 100 (such as a faucet, an angle valve housing, a shunt valve housing, etc.) with holes, the sidewall of the convex portion is provided with a fool-proof surface 16111a parallel to the axial direction, and the fool-proof surface 16111a is used for positioning the products 100, so that the product 100 applied in this embodiment needs to be correspondingly formed with a positioning surface on the hole wall, which is matched with the fool-proof surface 16111 a. A first mounting groove 16112 extending in the axial direction is formed in the chuck 1611, and both ends of the first mounting groove 16112 extend into the protruding portion 16111 and the bottom surface of the chuck 1611; the first mounting groove 16112 is opened at an outer wall of the chuck 1611. The side wall of the chuck 1611 is further provided with a first opening 16113 opposite to the opening of the first mounting groove 16112, and the first opening 16113 is located at the convex portion 16111. In addition, a pin 16114 is inserted into a side wall of the chuck 1611, and a middle portion of the pin 16114 is located in the first mounting groove 16112.

A second mounting groove 16121 extending along the axial direction is formed in the connecting rod 1612, the upper end of the second mounting groove 16121 extends to the upper end face of the connecting rod 1612, and the second mounting groove 16121 is opened on the side wall of the connecting rod 1612; in this embodiment, the top of the connecting rod 1612 and the bottom of the chuck 1611 are inserted into each other and fixed by screws to form the base 161, and when fixed in place, the first mounting groove 16112 and the second mounting groove 16121 are correspondingly communicated in the axial direction, and the opening of the first mounting groove 16112 and the opening of the second mounting groove 16121 are also correspondingly communicated with each other. The lateral wall spiro union of connecting rod 1612 has set screw 16122, and set screw 16122 is connected with the lateral wall of connecting rod 1612 with the opening of second mounting groove 16121 relatively, and its one end stretches into in second mounting groove 16121. The outer wall of the connecting rod 1612 is fixedly coupled with a stopper 16123 adapted to partially block the opening of the second mounting groove 16121 by means of a screw.

The clamp 162 is pivotally connected to the base 161 at a horizontal pivot axis and has a first end configured to extend into the aperture of the product 100 to abut the aperture wall of the product 100 and lock the product 100.

Specifically, as shown in fig. 8 to 10, the clamp 162 includes a lever portion 1621 and an operating portion 1622.

The rod part 1621 is a straight rod, is suitable for entering a groove formed by communicating the first mounting groove 16112 and the second mounting groove 16121 through an opening of the first mounting groove 16112 and an opening of the second mounting groove 16121, is rotatably connected with the pin shaft 16114, has a first end (upper end) extending into the convex part 16111 and provided with an abutting protrusion 16211 facing the first opening 16113, and has a second end (lower end) opposite to the positioning screw 16122, wherein the first end of the rod part 1621 constitutes a first end of the clamping member 162, and the second end of the rod part 1621 constitutes a second end of the clamping member 162; the pin 16114 forms a pivot for the clamp member 162. After the rod portion 1621 enters the base 161 from the opening of the first installation groove 16112 and the opening of the second installation groove 16121 and is pivoted to the pin 16114, the stopper 16123 is fixed to the outer wall of the connecting rod 1612 to limit the rotation range of the rod portion 1621.

The operating portion 1622 is fixedly connected to the second end of the rod portion 1621 and faces the opening of the second mounting groove 16121, and is provided with a positioning groove 16221 and a bearing pin 16222, and one side of the opening of the positioning groove 16221 deviates from the positioning screw 16122; the bearing pin 16222 is fixedly connected to the operation portion 1622 in parallel with the lever portion 1621 and penetrates the positioning groove 16221. In order to make the operation portion 1622 satisfy the operational requirement, the operation portion 1622 needs to protrude out of the opening of the second mounting groove 16121 (i.e., the outer wall of the base 161) during the rotation of the clamping member 162 relative to the base 161.

The first elastic member 163 acts on the base 161 and the clamping member 162 to abut the first end of the clamping member 162 against the hole wall of the product 100 and lock the product 100.

Specifically, as shown in fig. 9 and 10, the first elastic element 163 is a spring, which is installed in the second installation groove 16121, one end of which is sleeved on the portion of the positioning screw 16122 extending into the second installation groove 16121, and the other end of which abuts against the second end of the rod portion 1621. In this embodiment, when the operation portion 1622 is pressed by an external force, the second end of the rod portion 1621 rotates toward the side where the positioning screw 16122 is located, the first elastic member 163 compresses to store energy, the abutting protrusion 16211 on the first end of the rod portion 1621 retracts into the first opening 16113, and at this time, the product 100 can be easily sleeved on the protruding portion 16111 from top to bottom; when the product 100 is put in place, the pressing force on the operating part 1622 is released, the first elastic member 163 releases energy, the energy is released to be in place, the second end of the rod part 1621 rotates away from one side of the positioning screw 16122, the operating part 1622 protrudes out of the opening of the second mounting groove 16121, and the abutting protrusion 16211 on the first end of the rod part 1621 protrudes out of the first opening 16113 to abut against the hole wall of the product 100 and lock the product 100. It should be noted that, when the product 100 is not sleeved on the convex portion 16111, the rotation range of the rod portion 1621 relative to the base 161 is large, the structural stability is poor, and there is a possibility that the second end of the rod portion 1621 is separated from the first elastic member 163, so that the first elastic member 163 is separated from the positioning screw 16122, therefore, in this embodiment, the rotation range of the rod portion 1621 can be effectively limited by the stopper 16123, so as to ensure that the rod portion 1621 can always abut against the first elastic member 163.

Preferably, in this embodiment, the distance between the second end of the rod portion 1621 and the pivot thereof is greater than the distance between the first end of the rod portion 1621 and the pivot thereof, and when the first elastic member 163 abuts against the second end of the rod portion 1621, the moment arm on the side where the first elastic member 163 is located is longer, and under the same acting force, the moment applied to the rod portion 1621 by the first elastic member 163 is larger, so as to facilitate the lifting of the abutting force of the abutting protrusion 16211 on the product 100. It should be noted that the installation position of the first elastic element 163 in the base 1611 is not limited, and it only needs to satisfy the function of driving the rod 1621 to rotate to the abutting protrusion 16211 to keep abutting against the hole wall of the product 100.

In this embodiment, if the first end of the rod part 1621 is not provided with the abutting protrusion 16211, it can also reliably lock the product 100, and in the case of the abutting protrusion 16211, in order to achieve a better locking effect, the product 100 may be provided with a concave point on the hole wall thereof, into which the abutting protrusion 16211 can be correspondingly placed, during the molding process.
