[0005] The technical solution for realizing the purpose of the utility model is: a clamping structure in a paper-plastic cup leak detection device, including a bottom plate and an annular seat arranged above the bottom plate, the annular seat has at least two clamping claws for clamping the paper-plastic cup, and the annular seat is also provided with an adjustment mechanism for adjusting the size of the space enclosed by at least two clamping claws to clamp the paper-plastic cup, the bottom of the paper-plastic cup abuts against the bottom plate, and the clamping claw clamps the middle and upper part of the paper-plastic cup. The adjustment mechanism includes a guide rod, an adjustment nut and a spring, the annular seat has a first guide hole, the guide rod is installed in the first guide hole, the clamping claw is installed on one end of the guide rod, the spring is sleeved on the guide rod and is located between the clamping claw and the annular seat; the other end of the guide rod has a thread, and the adjustment nut is installed on the other end of the guide rod and is located outside the annular seat.

[0006] In this scheme, when clamping the paper plastic cup, the paper plastic cup is placed in the annular seat, and at least two clamping claws in the annular seat abut against the outer periphery of the upper and middle part of the paper plastic cup, forming a clamping state for the paper plastic cup. The size of the clamping force can be adjusted by the adjustment mechanism. At the same time, the bottom of the paper plastic cup abuts against the bottom plate, that is, the fixation of the paper plastic cup is completed. The structure is simple and convenient, without too many fixing parts and steps, which greatly improves the installation and fixing efficiency. When in use, if the clamping space for the paper plastic cup formed between the multiple clamping claws is small, the adjusting nut can be turned in the direction of the clamping claw. At this time, the clamping claw approaches the inner wall of the annular seat, and the spring is compressed. Otherwise, the operation is reversed to adjust the appropriate space for clamping the paper plastic cup. The operation is simple and convenient, and it can be completed by twisting the adjusting nut. The fixing structure of the annular seat and the bottom plate can be various, such as having a connecting piece between the two, or the two are fixed on the leak detection device respectively.
