These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, a detection device includes a detection device housing 1 and a cover 5 disposed on one side of the detection device housing 1. It also includes a telescopic wheel structure 2, which comprises a telescopic wheel groove 201 formed at the bottom of the detection device housing 1, a connecting plate 202 slidably connected to the telescopic wheel groove 201, a connecting post 203 symmetrically fixed at the bottom corner of the telescopic wheel groove 201, a telescopic post 204 disposed inside the connecting post 203, a wheel slide post 205 disposed at the bottom end of the telescopic post 204, a wheel slide groove 206 disposed at the bottom end of the wheel slide post 205, a sliding post 207 slidably connected to the wheel slide groove 206, a wheel 208 fixed to the bottom end of the sliding post 207, and a telescopic wheel structure 208 disposed on the telescopic wheel groove 204. The bottom plate 209 at the bottom of the wheel groove 201 and the engaging assembly set on the bottom of both sides of the detection device housing 1, the top of the telescopic column 204 is fixed with a spring, the connecting column 203 and the telescopic column 204 are slidably connected, the sliding column 207 is symmetrically distributed on both sides of the top of the wheel 208, and the engaging assembly includes a first clamping block groove 210 opened on both sides of the telescopic wheel groove 201, a second clamping block groove 211 opened on the outer wall of the first clamping block groove 210, a clamping block body 212 slidably connected to the inside of the first clamping block groove 210 and the second clamping block groove 211, a clamping block sliding column 213 fixedly connected to the inside of the first clamping block groove 210, and a pull groove 214 opened on the outer wall of the clamping block body 212.

[0030] It should be noted that by setting the telescopic wheel structure 2, when using the detection device housing 1, the pull groove 214 can be pulled by hand to allow the wheel pull column 205 and wheel 208 to extend into the telescopic wheel groove 201, so that the connecting plate 202 is clamped by the base plate 209 and the clamping block body 212. When the detection device housing 1 is not being dragged, the telescopic wheel structure 2 can be stored at the bottom of the detection device housing 1 so that the base plate 209 is on the ground, making the portable surveying device more stable.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, springs are provided on the outer wall of the clamping block body 212, and the clamping block body 212 and the clamping block slide column 213 are designed to be slidably connected.

[0032] It should be noted that by setting up the support structure 3, rotating the first support plate 303 and adjusting the bolt 304 can make the second support plate 305 more suitable for the dragging conditions of the current terrain, so that the detection device can be adjusted to the most comfortable angle for the operator under different slope conditions, so as to drag.

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the support structure 3 is located on one side of the outer shell 1 of the detection device and is used to support the tilting and dragging of the outer shell 1 of the detection device.

[0035] When using this utility model, the detector housing 1 can be pulled by hand along the pull groove 214 so that the pull rod 205 and the wheel 208 can extend into the telescopic wheel groove 201, so that the connecting plate 202 is clamped by the base plate 209 and the clamping block body 212. The detector housing 1 is provided with a pull rod structure 4 on the top side near the support storage groove 301. The pull rod structure 4 includes a handle groove 401 on one side of the top of the detector housing 1, a pull rod telescopic groove 402 on both sides of the bottom end of the handle groove 401, a pull rod telescopic rod 403 slidably connected to the inside of the pull rod telescopic groove 402, a handle body 404 fixedly connected to the top of the pull rod telescopic rod 403, a first locking block telescopic groove 405 on one side of the pull rod telescopic groove 402, a second locking block telescopic groove 406 on the other side of the first locking block telescopic groove 405, a first telescopic locking block 407 slidably connected to the inside of the first locking block telescopic groove 405, and a handle body 404 fixedly connected to the first telescopic groove 402. When the second telescopic block 408 at one end of the retractable block 407 is not being dragged, the telescopic wheel structure 2 can be retracted to the bottom of the detector housing 1 so that the base plate 209 is on the ground, making the portable surveying device more stable. Rotating the first support plate 303 and adjusting the bolt 304 allows the second support plate 305 to better suit the dragging conditions of the current terrain. The groove 401 has a slot in the middle to facilitate gripping the handle body 404. When the telescopic rod 403 is pulled out, the second telescopic block 408 can pop out the support structure 3. After adjusting the adjusting bolt 304 between the first support plate 303 and the second support plate 305, the ground, box and person can be formed into a stable structure more quickly. When it is necessary to store miscellaneous items, rotating the switch knob 603 will disengage the cover 5 and the switch knob 602 from the switch knob 603, making it easy to store items inside the detector housing 1.
