[0002] During urban planning and engineering construction, it is necessary to use a surveying instrument to measure the construction area in order to draw the ground graphics and location information of the construction area. In order to facilitate the user's operation during the surveying process, the surveying instrument is often installed on a support frame before the surveying work is carried out. Most existing support frames adopt a tripod structure. The bottom of the three supporting legs of the tripod are provided with a tip. When in use, the tip of each supporting leg is in contact with the ground to ensure the stability of the tripod. However, when surveying in urban areas with complex geographical conditions, if the supporting surface under one of the supporting legs of the tripod is a steeper slope, there is a risk of sliding between the tip and the supporting surface, making it difficult to ensure the stability of the supporting leg, which has an unfavorable impact on the measurement results.

For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0028] like Figures 1 to 3 As shown, the preferred embodiment of the support leg of the utility model comprises:

[0029] A support leg body 1, the support leg body 1 comprises a support portion 11 and a top portion 12 arranged in sequence from top to bottom;

[0030] A mounting plate 2, the mounting plate 2 is rotatably sleeved on the outer side of the lower end of the support portion 11;

[0031] The connecting member 3 has one end hinged to the outside of the mounting plate 2 and the other end of the connecting member 3 has a nail hole 321 for penetrating the nail body 4 .

[0032] When the support leg is set on a horizontal support surface, just place the top tip on the support surface; when the support leg is set on an inclined support surface, rotate the mounting plate 2 to make the connecting member 3 rotate horizontally, and rotating the connecting member 3 can make the connecting member 3 swing up and down, so that the nail hole is perpendicular to the support surface, and then the nail body 4 is passed through the nail hole 321 and nailed to the support surface to stably connect the support leg to the support surface. Specifically, the connecting member is connected to one side of the mounting plate by rotating the shaft, and the mounting plate can be rotated to be parallel to the support surface, and then the connecting member 3 is swung up and down to make the nail hole perpendicular to the support surface, and the mounting plate is connected to the outer side of the lower end of the support part by rotating it. The support leg of the utility model can be applied to support surfaces with various inclined directions; the support leg of the utility model can not only be stably placed on the horizontal support surface by using the top portion 12, but also can be stably connected to the inclined support surface by using the connecting piece 3 and the nail body 4, thus avoiding sliding between the support leg and the inclined support surface and ensuring the support stability of the support leg; for horizontal support surfaces or support surfaces with a small inclined angle, there is no need to use a connecting piece, and the support leg can be placed on the support surface by using the top portion; therefore, the support leg of the utility model can not only be applied to inclined support surfaces with various inclined angles, but can also be quickly and conveniently placed on a horizontal support surface by using the top portion 12.

[0033] Among them, the support part 11 is a support rod, and a mounting hole is provided at the lower end of the support rod, a top rod is movably inserted in the mounting hole, and the top part 12 is arranged at the lower end of the top rod. Specifically, when the support leg needs to be placed on an inclined surface, the top rod is moved upward so that most of the top rod is retracted into the mounting hole to avoid the lower end of the top rod extending too long and interfering with the rotation of the connector 3, thereby ensuring that the up and down swing angles of the connector 3 are large enough, thereby ensuring that the support leg can be applied to support surfaces with various inclined angles. When the support leg needs to be placed on a horizontal ground, the top rod is moved downward so that the downward extension length of the top rod is increased, and the support leg is placed on the ground by using the tip of the top rod to abut against the ground; at this time, the connector 3 does not work.

[0034] Furthermore, in order to facilitate the adjustment of the extension length of the top rod and keep the length of the top rod fixed after extension, in this embodiment, the mounting hole is provided with an internal thread, the top rod is provided with an external thread, and the top rod is threadedly assembled in the mounting hole. In other embodiments of the utility model, the internal thread may not be provided on the inner side of the mounting hole, nor may the external thread be provided on the outer side of the top rod. By providing a locking screw extending radially along the support rod at the lower end of the support rod, by screwing the locking screw, the threaded end of the locking screw passes through the hole wall of the mounting hole and abuts against the outer side of the top rod, and the top rod is locked or unlocked by screwing the locking screw.

[0035] In this embodiment, the connecting member 3 includes a first plate body 31 and a second plate body 32 arranged at an angle to the first plate body 31; one end of the first plate body 31 is hinged to the outside of the mounting plate 2, and the other end of the first plate body 31 is fixedly connected to the second plate body 32, and the nail hole 321 is provided on the second plate body 32. Specifically, the first plate body 31 and the second plate body 32 are arranged vertically. In other embodiments of the utility model, the first plate body 31 and the second plate body 32 can be at an acute angle or an obtuse angle. When in use, the second plate body 32 is adjusted to be flush with the inclined support surface, and then the second plate body 32 is connected to the support surface using the nail body 4.

[0036] To facilitate separation of the second plate 32 from the support surface after the surveying is completed, in this embodiment, a prying opening 322 is provided at one end of the second plate 32 facing the nail tip of the nail body 4. Specifically, the pry bar is inserted into the prying opening 322 to pry the second plate 32 off the support surface.

[0037] Further, at least two nail holes 321 are provided, each nail hole 321 is arranged at intervals, and the prying opening 322 is provided between two adjacent nail holes 321. In this embodiment, two nail holes 321 are provided, and the two nail holes 321 are arranged symmetrically about the center of the prying opening 322. When the second plate body 32 is pried off the supporting surface through the prying opening 322, the force of the prying rod on the second plate body 32 can act on the two nail bodies 4 at the same time, so that the two nail bodies 4 can be pried off the supporting surface at the same time.

[0038] In this embodiment, in order to facilitate the adjustment of the position of the connecting member 3 and the top portion 12, the support rod is a telescopic rod. Specifically, there are various structural forms of the telescopic rod, such as the telescopic rod is configured to include a sleeve and a rod body inserted in the sleeve and a locking mechanism for locking the rod body, the locking mechanism can be a locking screw inserted in the sleeve wall, the threaded section of the locking screw passes through the sleeve wall and abuts against the outer side of the rod body. The rod body can only move axially relative to the sleeve, and cannot rotate coaxially relative to the sleeve.

[0039] In this embodiment, the mounting plate 2 can rotate around the axial direction of the support portion 11, but cannot move along the length direction of the support portion 11. Specifically, a through hole is provided in the middle of the mounting plate 2, and the support portion 11 is inserted in the through hole.
