[0030] The locking assembly is located at the rear of the protective shell 1 and comprises a locking plate 8 and two symmetrical locking rods 9, which are used for locking and limiting the measuring instrument main body 13 in the containing groove 2; the locking plate 8 is fixed to the rear end of the protective shell 1 through bolts, and the side facing the protective shell 1 is provided with two hinged plates 10; the two hinged plates 10 are respectively hinged to the rear ends of the corresponding locking rods 9, so that the locking rods 9 can rotate in a small range in the limited guide groove 7; the locking rod 9 penetrates through the corresponding position of the guide groove 7, and the front end is provided with a clamping groove 11 above and a telescopic rod 12 below;

[0031] The measuring instrument body 13 is located in the accommodating groove 2, and two symmetric avoiding grooves 14 are formed in the bottom of the measuring instrument body 13; the top of the entrance of the avoiding groove 14 is provided with a clamping plate 15 matched with the clamping groove 11, and when the clamping plate 15 enters the clamping groove 11, the measuring instrument body 13 is locked in the accommodating groove 2 of the protective shell 1 and cannot move any more.

[0032] In the embodiment, a slot is formed in the middle of each side plate of the protective shell 1, and a magnetic block one 16 is arranged at the bottom of the slot; two symmetric magnetic block twos 17 are arranged on the second protective plate 4; the magnetic block two 17 and the corresponding magnetic block one 16 are attracted to each other. When the staff does not need to operate the keys, the magnetic block one 16 and the magnetic block two 17 are attracted to each other, so that the top of the second protective plate 4 enters the slot, and the key area of the measuring instrument body 13 can be protected. When the staff needs to operate the keys, the second protective plate 4 can be manually lifted upwards, so that the corresponding magnetic block one 16 and the magnetic block two 17 are separated; then, the second protective plate 4 is slid along the sliding groove 6 on the rear end side wall of the protective shell 1 until the key area is completely exposed to the outside, so as to facilitate the operation of the staff; after the key operation is completed, the staff can slide the second protective plate 4 to return to the initial position; under the magnetic force of the magnetic block one 16 and the magnetic block two 17, the second protective plate 4 will move downwards by a distance, and the sliding block 5 on the inner side of the two side plates will move downwards along the sliding groove 6 until the magnetic block one 16 and the magnetic block two 17 contact each other.

[0033] In addition, the rear end upper portion of the protective shell 1 of the embodiment is further provided with an unlocking plate 18 for separating the measuring instrument body 13 from the locking assembly, so as to facilitate taking out the measuring instrument body 13 from the accommodating groove 2.
