Specifically, as shown in fig. 4 and 5, the clamp 2 includes a lever portion 21 and an operating portion 22.

The rod part 21 adopts a straight rod, which is suitable for entering a groove formed by communicating the first mounting groove 112 and the second mounting groove 121 through the opening of the first mounting groove 112 and the opening of the second mounting groove 121, the rod body is rotatably connected with the pin shaft 114, the first end (upper end) of the rod part extends into the convex part 111 and is provided with an abutting bulge 211 facing the first opening 113, and the second end (lower end) of the rod part is opposite to the positioning screw 122, wherein the first end of the rod part 21 forms the first end of the clamping element 2, and the second end of the rod part 21 forms the second end of the clamping element 2; the axis of the pin 114 constitutes a first axis. After the rod 21 enters the base 1 from the opening of the first mounting groove 112 and the opening of the second mounting groove 121 and is pivoted to the pin 114, the stopper 123 is fixed to the outer wall of the connecting rod 12 to limit the rotation range of the rod 21.

In order to make the operation portion 22 satisfy the operational requirement, the operation portion 22 is required to protrude from the opening of the second installation groove 121 (i.e. the outer wall of the base 1) during the rotation of the clamping member 2 relative to the base 1.

The first elastic element 3 acts on the base 1 and on the clamping element 2 so as to keep the first end of the clamping element 2 in abutment against the wall of the hole of the product 100.

Specifically, as shown in fig. 4 and 5, the first elastic element 3 is a spring, which is installed in the second installation groove 121, one end of which is sleeved on the portion of the positioning screw 122 extending into the second installation groove 121, and the other end of which abuts against the second end of the rod portion 21. In this embodiment, when the operation portion 22 is pressed by an external force, the second end of the rod portion 21 rotates toward the side where the positioning screw 122 is located, the first elastic member 3 compresses to store energy, and the abutting protrusion 211 on the first end of the rod portion 21 is locked into the first opening 113, at this time, the product 100 can be easily sleeved on the protrusion 111 from top to bottom; when the product 100 is put in place, the pressing force on the operating part 22 is released, the first elastic part 3 releases energy, the energy is released to be in place, the second end of the rod part 21 is rotated away from the side of the positioning screw 122, the operating part 22 protrudes out of the opening of the second mounting groove 121, and the abutting protrusion 211 on the first end of the rod part 21 protrudes out of the first opening 113 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 protrusion 111, the rotation range of the rod 21 relative to the base 1 is large, the structural stability is poor, and the second end of the rod 21 is separated from the first elastic element 3, which may cause the first elastic element 3 to be separated from the positioning screw 122, therefore, in this embodiment, the rotation range of the rod 21 can be effectively limited by the stop 123, so as to ensure that the rod 21 can be always abutted against the first elastic element 3.

Preferably, in this embodiment, the distance between the second end of the rod portion 21 and the first axis is greater than the distance between the first end of the rod portion 21 and the first axis, when the first elastic member 3 abuts against the second end of the rod portion 21, the moment arm on the side where the first elastic member 3 is located is longer, and under the same acting force, the moment applied to the rod portion 21 by the first elastic member 3 is larger, so as to facilitate increasing the abutting force of the abutting protrusion 211 on the product 100. It should be noted that the installation position of the first elastic element 3 in the base 1 is not limited, and it only needs to satisfy the function of driving the rod 21 to rotate to the abutting protrusion 211 to keep abutting against the hole wall of the product 100.

In this embodiment, if the first end of the rod 21 is not provided with the abutting protrusion 211, it can also reliably lock the product 100, and in the case of the abutting protrusion 211, 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 abutting protrusion 211 to be inserted into during the molding process.
