[0033] The quick assembly includes a hoop 20, a limiting slide 21, a through hole 22, an indicator plate 23 and a telescopic block 25. The hoop 20 is clamped at the lower end of the fixed end of the hydraulic rod 16, the limiting slide 21 is fixed to the side of the hoop 20, the through hole 22 is opened in the middle of the side of the limiting slide 21, the indicator plate 23 is inserted in the limiting slide 21, and one end of the telescopic block 25 is movably connected to the lower section of the side of the indicator plate 23, and the other end is inserted in the through hole 22;

[0034] The quick assembly also includes a limit plate 24, which is fixed to the upper end of the indicator plate 23;

[0035] The indicator plate 23 is slidably connected to the upper surface of the pressing plate 14;

[0036] The hoop 20 plays a connecting role, the limiting slide groove 21 plays a limiting and supporting role, the through hole 22 plays a connecting role, the indicating plate 23 plays an indicating role, the limiting plate 24 plays a limiting role, and the telescopic block 25 plays a connecting role.

[0037] Working principle:

[0038] Before placing the fixture table 12, press the telescopic block 25 in the through hole 22 to make the indicator plate 23 fall along the limiting slide groove 21 until the limiting plate 24 falls on the upper end of the limiting slide groove 21, place the fixture table 12 at one end of the support table 11, push the indicator plate 23 upward with one hand, and push the fixture table 12 with the other hand to make the upper end of the pressure plate 14 move in contact with the indicator plate 23, and ensure that the indicator plate 23 moves through the groove 140.

[0039] This step allows the groove 140 to be quickly placed directly below the hydraulic rod 16, saving time and effort and improving detection efficiency.

[0040] See also Figure 4-5 This embodiment is based on the above embodiment and further includes:

[0041] The storage assembly includes a storage slot 30 and an arc-shaped slot 31. The arc-shaped slot 31 is provided on the side of the storage slot 30, and the storage slot 30 is engaged with the lower end of the support platform 11 through the arc-shaped slot 31;

At the same time, the magnet block 34 on one side of the fixed block 32 is adsorbed in the adsorption groove 33 on the other fixed block 32. The asphalt that is broken during the shearing process will fall into the receiving groove 30.

[0046] This step makes it easier to collect the loose asphalt that has broken apart during the shearing process, preventing it from scattering and affecting the environment, and reducing the intensity of subsequent cleaning.
