The beneficial effect produced by the utility model is that when the lever is retracted, the sleeve passes through the reserved hole of the floor slab, and then the lever extends and pulls the sleeve upward to make the upper surface of the lever contact with the lower surface of the floor slab, and the scale corresponding to the upper surface of the floor slab and the scale bar is the thickness of the floor slab. The measurement process is convenient, the reading is accurate, and the measurement efficiency can be improved; and multiple levers are positioned to ensure that the lever is in stable contact with the lower surface of the floor slab, thereby improving the accuracy of the measured value.
[0004] Some problems were found when using the above-mentioned existing device for measuring floor thickness. First, the barrier rod contacts the lower surface of the floor, and then a visual reading is taken. To avoid errors in the reading, it is necessary to bend over as much as possible to make it parallel to the floor, and at the same time, it is necessary to lift the device upwards, which makes it difficult to use.

[0021] In this embodiment, the blocking rod 103 can be stuck under the floor, and the extrusion spring 403 can provide a certain thrust for the upper clamping rod 401. The upper clamping rod 401 will be pushed down by the limit slip ring 4, and the upper clamping rod 401 will be stuck on the floor, so that the upper clamping rod 401 and the blocking rod 103 cooperate with each other to clamp the device on the floor. Figure 1 As shown, the user can directly let go of the hands to visually read the readings. The limit slip ring 4 is made of a transparent material, and an auxiliary pointer is engraved on the surface to assist the measurement personnel in reading the readings, so that the measurement personnel do not need to bend over and look straight ahead to read the readings.
[0022] Among them, in order to achieve the purpose of limiting the rotation angle of the blocking rod 103, the present device is implemented by the following technical solution: protrusions 104 are fixedly connected on both sides of the measuring rod 1 and located above the storage slot 101, the protrusions 104 cooperate with the blocking rod 103, and a limiting sliding hole 205 is opened in the connecting plate 204, and the limiting sliding hole 205 is slidably matched with the guide rod 402.

The limiting slide hole 205 and the guide rod 402 slide together, so that the handle 203 moves downward to drive the connecting plate 204 to move without interfering with the guide rod 402. The guide rod 402 is mainly used to limit the extrusion spring 403 from being bent during the compression process.
