[0007] Preferably, a sleeve is fixedly mounted on the rear surface of the test head, and a limiting sliding groove is longitudinally provided on the rear surface of the test head and below the sleeve.

[0008] Preferably, a guide rod is movably mounted on the upper surface of the rear end of the shielding cover, a stop block is fixedly mounted on the upper end surface of the guide rod, and a limiting slider is fixedly mounted on the rear surface of the shielding cover.

[0009] Preferably, the upper end of the guide rod is embedded in a sleeve, and a spring is sleeved on the surface of the guide rod inside the sleeve.

[0010] Preferably, the limiting sliding block is embedded in the limiting sliding groove, and the inner diameter of the shielding cover is larger than the diameter of the test head.

[0011] Preferably, the upper end of the spring is fixed to the stop block, and the lower end of the spring is fixed to the inner lower surface of the sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by arranging the test head and the shielding cover in a manner that cooperates with each other, when the coating thickness gauge is not in use, the shielding cover is pulled down, and the shielding cover will use the stop block to compress the spring when it is pulled down. When the shielding cover is pulled down to a position flush with the test head, the shielding cover is rotated, and the shielding cover rotates with the guide rod as the center, and then the external force for pulling down the shielding cover is released. At this time, the stop block of the shielding cover will rise under the pushing action of the spring until the shielding cover is stuck at the lower end of the test head, so that the test head can be protected when not in use to avoid damage to the test head.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3 A portable handheld coating thickness gauge is shown, comprising a thickness gauge body 1 and a test head 4. The test head 4 is fixedly installed on the bottom of the thickness gauge body 1, a display screen 2 is provided on the upper surface of the thickness gauge body 1, a button 3 is provided on the front surface of the thickness gauge body 1, a shielding cover 5 is provided at the rear of the thickness gauge body 1, and a battery cover 6 is fixedly embedded on the rear surface of the thickness gauge body 1.

[0020] A sleeve 401 is fixedly installed on the rear surface of the test head 4, and a limit slide groove 402 is longitudinally provided on the rear surface of the test head 4 and below the sleeve 401. The cooperation between the limit slide groove 402 and the limit slider 501 can assist the vertical lifting of the shielding cover 5; a guide rod 502 is movably installed on the upper surface of the rear end of the shielding cover 5, and a stop block 503 is fixedly installed on the upper end surface of the guide rod 502. The limit slider 501 is fixedly installed on the rear surface of the shielding cover 5; the upper end of the guide rod 502 is embedded with a In the sleeve 401, a spring 504 is sleeved on the surface of the guide rod 502 located inside the sleeve 401, and the spring 504 has an upward thrust on the stop block 503; the limiting slider 501 is embedded in the limiting slide groove 402, and the inner diameter of the shielding cover 5 is larger than the diameter of the test head 4, and the shielding cover 5 can shield and protect the lower end of the test head 4 when not in use; the upper end of the spring 504 is fixed to the stop block 503, and the lower end of the spring 504 is fixed to the inner lower surface of the sleeve 401.

[0021] It should be noted that the utility model is a portable handheld coating thickness gauge. During use, when the coating thickness gauge is not in use, the shielding cover 5 is pulled down, and the shielding cover 5 will use the stop block 503 to compress the spring 504 when being pulled down. When the shielding cover 5 is pulled down to a position flush with the test head 4, the shielding cover 5 is rotated, and the shielding cover 5 rotates around the guide rod 502, and then the external force for pulling down the shielding cover 5 is released. At this time, the stop block 503 of the shielding cover 5 will rise under the pushing action of the spring 504 until the shielding cover 5 is stuck at the lower end of the test head 4, so that the test head 4 can be protected when not in use to avoid damage to the test head 4.
