[0026] Please refer to Figure 1 and Figure 2A motor vehicle speedometer, comprising a body 1 and a speed measuring laser emitting port 17, the upper surface of the body 1 is electrically connected to the speed measuring laser emitting port 17, the surface of the body 1 is provided with a data display screen 18, the body 1 is a common temperature tester on the market, both left and right sides of the body 1 are fastened with assembly parts 6, the outer side of the assembly part 6 is movably sleeved with a metal plate 2, the front side of the metal plate 2 is fastened with a stainless steel handle 3, and the stainless steel handle 3 is a semicircular stainless steel handle, by setting two sets of metal plates 2, the body 1 can be protected when the device is not used, thereby preventing the body 1 from being damaged and piled up The metal plate 2 is stably fixed to the outside of the machine body 1 through the cooperation between the support block 15 and the protrusion 11, so as to prevent the metal plate 2 from being separated from the machine body 1 due to vibration, thereby ensuring the normal use of the device and providing convenience for the operator's work. A built-in device installation area 8 is provided inside the metal plate 2, and two groups of B springs 13 are fastened to the right inner wall of the built-in device installation area 8. The left end of the B spring 13 is fastened to the right side of the machine body 1. By setting the B spring 13, when the metal plate 2 is pushed to cover the machine body 1, the B spring 13 will be The metal plate 2 is squeezed by the support block 15, and after the support block 15 is pushed into the groove 9 by the protrusion 11, the B spring 13 will bounce the metal plate 2 back to the initial position quickly, so that the device can stably protect the body 1 and can also make the metal plate 2 quickly detach from the body 1, thereby ensuring the normal use of the body 1, which is suitable for promotion. The front side of the assembly 6 is fastened with a protrusion 11, the front side of the built-in device installation area 8 is provided with a groove 9, the front inner wall of the groove 9 is fastened with an A spring 10, the rear end of the A spring 10 is fastened with a support block 15, and the inside of the metal plate 2 is fastened with two groups of C springs 14, and the right end of the C spring 14 is fastened with a support block 15. A blocking block 12 is fastened, and the right side of the blocking block 12 extends into the groove 9. By setting the cooperation between the blocking block 12 and the supporting block 15, when the blocking block 12 presses against the supporting block 15, the supporting block 15 will not be able to enter the groove 9, so that the protrusion 11 cannot push the supporting block 15, thereby fixing the position of the metal plate 2 when protecting the body 1, and when the blocking block 12 is separated from the groove 9, the supporting block 15 can be pushed into the groove 9 by the protrusion 11, so that the position of the metal plate 2 is no longer fixed, thereby ensuring the normal use of the device, and the data display screen is electrically connected to the speed measurement laser emission port.
