DETAILED DESCRIPTION

[0018] The following will be combined with the Figures 1-3 The application will be further described in detail.

[0019] The application embodiment discloses a portable meter, which refers to Figures 1-3 , comprising a meter body 1, two connecting columns 2 are symmetrically installed on the side wall of the meter body 1, a U-shaped seat 3 is fixedly installed at the end of each of the two connecting columns 2, a connecting seat 5 is hingedly connected to the U-shaped seat 3 through a rotating shaft 4, a fixing sleeve 7 is fixedly installed at the end of each of the two connecting seats 5, a same U-shaped handle 8 is slidably arranged in the interior of the two fixing sleeves 7, and a clamping assembly 9 is installed at the top of the meter body 1, the clamping assembly 9 comprises a fixing block 91 fixedly installed at the top of the meter body 1, a sliding groove 92 is formed at each end of the fixing block 91, a clamping block 93 is slidably arranged in the interior of the sliding groove 92, and a spring 94 is fixedly installed between the clamping block 93 and the side wall of the sliding groove 92.

[0020] Here by the U-shaped handle 8 into the fixed sleeve 7 inside, in pressing the clamping block 93, the clamping block 93 can extrude spring 94 shrink into the slide groove 92 inside, then rotate the fixed sleeve 7, make the fixed sleeve 7 rotate to the meter body 1 upside, loose the clamping block 93, at this time the clamping block 93 under the action of spring 94 elastic stretch out the slide groove 92, so that the fixed sleeve 7 can be clamped, realize the folding of the device, reduce the space occupation of the device, then through the U-shaped handle 8 can carry the device, improve the portability of the device.

[0021] With reference to Figure 1 , the upper side of the U-shaped seat 3 is inserted with a limiting pin 6, and the connecting seat 5 is provided with a limiting hole matched with the limiting pin 6.

[0022] Here by setting the limiting pin 6 and the limiting hole, the limiting pin 6 is matched with the limiting hole, so that the fixed sleeve 7 can be limited.

[0023] With reference to Figure 1 , the outer wall of the fixed sleeve 7 is threadedly connected with a locking bolt 71 for limiting the movement of the U-shaped handle 8.

[0024] Here by setting the locking bolt 71, the movement of the U-shaped handle 8 can be limited, so that the length of the U-shaped handle 8 can be adjusted.

[0025] With reference to Figure 2 , the end of the U-shaped handle 8 is sleeved with an anti-skid sleeve 81.

[0026] Here by installing the anti-skid sleeve 81 on the U-shaped handle 8, the meter body 1 can be easily pushed to move.
