[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Figure 1 is a schematic structural diagram of the present utility model. Figure 2 is a front view structural diagram of the present utility model.

[0023] The solution of this embodiment provides a fixed automatic retractable ruler, including a bolt 3, an elastic ruler 4, a fixing block 5, a first clamping piece 1 and a second clamping piece 2. The first clamping piece 1 and the second clamping piece 2 are symmetrically arranged at equal distances. Both the first clamping piece 1 and the second clamping piece 2 have a fixing groove; the bolt 3 is arranged on one side of the first clamping piece 1 and penetrates through one side of the first clamping piece 1; the elastic ruler 4 is arranged on the upper part of the first clamping piece 1; the fixing block 5 is arranged on the upper part of the second clamping piece 2; wherein, the second clamping piece 2 has the same structure as the first clamping piece 1, as Figure 1 and Figure 2As shown in the figure, the first clip 1 has a short side and a long side. The bolt 3 passes through the short side, which is more stable during fixation. A gasket 301 is provided at one end of the bolt 3. When in use, the friction force is increased through the gasket 301, and at the same time, the fixing part is prevented from being damaged when the bolt 3 is fixed. Sliders are provided at the lower parts of the elastic ruler 4 and the fixing block 5, and the sliders are installed in the sliding grooves 101 opened on the upper part of the second clip 2. The sliding grooves 101 are opened at a distance of half of the upper surface of the first clip 1 and the second clip 2. By opening at half of the distance, when the elastic ruler 4 pulls the ruler strip 401, the excessive pulling force between the two is avoided, and the elastic ruler 4 and the fixing block 5 are prevented from being pulled out.

[0024] The working principle of the present utility model:

[0025] When in use, by providing two symmetrical first clips 1 and second clips 2, a detachable elastic ruler 4 and a fixing block 5 are provided on the upper parts of the first clip 1 and the second clip 2. The distance between the two is controlled through the fixation of the first clip 1 and the second clip 2. When in use, two people can accurately measure the plate heat exchanger within a safe range, thereby avoiding frequent manual measurement by personnel close to the plate heat exchanger. At the same time, the distance between the first clip 1 and the second clip 2 can be lengthened according to the measured plate, so as to change the distance of the elastic ruler 4, which is convenient to use.
