[0027] In this embodiment, by setting up a protective mechanism 2, the display screen part of the measuring instrument body 1 can be shielded and protected to prevent it from being damaged by external objects, and a cross bar 22 is set, and a sliding piece 23 and a sliding rod 24 are provided inside the cross bar 22, and the sliding piece 23 and the sliding rod 24 can slide in the sliding groove 25 opened on the cross bar 22, so that the protective cover 21 can be slid and adjusted to change its position. In addition, the protective cover 21 is rotatably connected to the sliding rod 24, and the protective cover 21 can be flipped and adjusted after sliding to a certain position, so that the protective cover 21 will not affect the normal measurement and use of the measuring instrument body 1, and a clamping block 27 is set, and the clamping block 27 can slide into the fixed block 31, and a clamping hole that matches the clamping rod 33 is opened on the clamping block 27, so that the clamping block 27 can be clamped and connected with the clamping rod 33, thereby ensuring the stability of the use of the protective cover 21.

[0028] Example 2

[0029] like Figure 1-Figure 6 As shown, a fixing mechanism 3 is provided on one side of the measuring instrument body 1, and the fixing mechanism 3 includes a fixing block 31, and the fixing block 31 is fixedly connected to the measuring instrument body 1. The clamping block 27 runs through the interior of the fixing block 31, and the clamping block 27 is slidably connected to the fixing block 31. A sliding sleeve block 32 is sleeved inside the fixing block 31, and the sliding sleeve block 32 is slidably connected to the fixing block 31. A clamping rod 33 is fixedly connected to one side of the sliding sleeve block 32, and the clamping rod 33 is slidably connected to the fixing block 31. A spring 34 is provided on one side of the sliding sleeve block 32 away from the clamping rod 33, and one end of the spring 34 is fixedly connected to the outer surface of the sliding sleeve block 32, and the other end of the spring 34 is fixedly connected to the inner wall of the fixing block 31. An adjusting block 35 is provided at one end of the sliding sleeve block 32, and the adjusting block 35 is fixedly connected to the sliding sleeve block 32.

[0030] In this embodiment, by setting up a fixing mechanism 3, it can be used in conjunction with the protective mechanism 2 to indirectly fix the protective cover 21, and the sliding sleeve block 32 is set, which can not only slide the compression spring 34, but also drive the clamping rod 33 to slide at the same time. Then, when the clamping block 27 enters the fixing block 31, the clamping rod 33 will automatically reset under the action of the elastic force generated by the compression of the spring 34, and be engaged with the clamping block 27, so as to achieve the purpose of fixing the clamping block 27 and the protective cover 21.

[0031] Working principle:

[0032] like Figure 1-Figure 6As shown, when the utility model is in use, if the measuring instrument body 1 is carried or temporarily idle, the protective cover 21 can be used to protect the display screen. At this time, the protective cover 21 in the flipped state is reset, and the protective cover 21 is rotated around the slide bar 24 until the protective cover 21 is in a position parallel to the display screen of the measuring instrument body 1, and then the protective cover 21 is slid. When the protective cover 21 slides, the slide bar 24 drives the sliding piece 23 to slide in the slide groove 25 provided on the cross bar 22, and at the same time, the adjustment block 35 is slid, and the adjustment block 35 drives the sliding piece 23 to slide in the slide groove 25 provided on the cross bar 22. The sleeve block 32 slides in the fixed block 31. At this time, the sliding sleeve block 32 will synchronously drive the card rod 33 and compress the spring 34 at the same time, so that the spring 34 generates elastic force. When the protective cover 21 continues to slide, it will drive the card block 27 to enter the fixed block 31. When the sliding piece 23 cannot continue to slide, the adjustment block 35 can be loosened. At this time, the elastic force of the spring 34 will reset the fixed block 31 and the card rod 33, and make the card rod 33 pass through the inside of the card block 27, so as to indirectly fix the protective cover 21, and then the display screen of the measuring instrument body 1 is convenient to be protected.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
