[0038] Example 3

[0039] The structure and principle of Example 3 are similar to those of Example 1 or 2, except that: a sliding connection method for the storage plate in the cavity is provided, sliders 8 are provided at both ends of the storage plate, and slide grooves 9 are provided at both ends of the cavity. The size of the slider matches the size of the slide groove, and the storage plate slides in the cavity through the slider and the slide groove.

[0040] In embodiment 3, a limit block 10 is provided at the end of the slideway outside the cavity. The limit block is used to limit the movement track of the slider in the slideway, thereby limiting the length of the placement plate extending from the cavity to prevent the placement plate from completely falling off from the cavity.

[0041] In Example 3, a pull plate 11 is provided on the outer side of the storage plate, and the pull plate is used to limit the storage plate to prevent the storage plate from being completely accommodated in the cavity and unable to be taken out. The pull plate and the above-mentioned limit block work together to limit the range of movement of the storage plate in the cavity. In order to ensure that the storage plate can be smoothly pulled out of the cavity, a pull block 12 is provided on the pull plate, and the pull block and the storage plate are respectively located on both sides of the pull plate. The operator pulls the storage plate out of the cavity through the pull block.

[0046] In Example 5, a limiting structure 18 is preferably provided between the stretch ruler and the surveying ruler. The limiting structure includes a plurality of limiting holes 18-1 arranged at intervals at the bottom of the stretch ruler, a fixing plate 18-2 provided on the surveying ruler, and limiting bolts 18-3 matching the limiting holes. The fixing plate is located directly below the area where the limiting holes are located. A threaded hole is provided on the fixing plate on the same plane as the axis of the limiting hole. The threaded hole matches the limiting bolt. The limiting bolt is screwed into different limiting holes to achieve control of the length of the stretch ruler extending out of the sliding slot.

[0047] The working principle of this utility model:

[0048] When in use, the pull block is pulled down to make the placement plate slide out from the cavity, and then the mapping pen is placed in the placement slot; then the mapping pen is limited in the placement slot through the cooperation of the arc clamp and the downward pressure mechanism, and after the placement is completed, the pull plate is pushed up to make the placement plate re-enter the cavity. In this process, the pull plate and the ruler body are limitedly connected through the sleeve and the rubber column, so that the ruler body can carry the mapping pen, which is convenient for the staff to take out the mapping pen for use at any time, improving work efficiency.

[0049] In addition, by rotating the limit bolt to separate the limit bolt from the limit hole, the extension ruler can be directly pulled to adjust the length of the entire ruler. After adjusting to the appropriate length, the limit bolt is rotated in the opposite direction to make the limit bolt match the corresponding limit hole, so that the extension ruler after the length adjustment can be used for limited use.
