[0023] Clearly and completely describe the technical scheme in the embodiments of the utility model in combination with the drawings in the embodiments of the utility model, in the description of the utility model, it is understood that the orientation or position relation indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like is the orientation or position relation based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] As Figure 1 , Figure 2 , Figure 3 Indicated, a total station mounting bracket, including base 1 and several legs 2, base 1 is rotatably connected with several sleeves 3, wherein base 1 is used for installing total station to carry out subsequent measurement work, several sleeves 3 are respectively slidably connected with several legs 2, a limiting block 4 is slidably arranged on the sleeve 3, a plurality of limiting grooves 5 are formed along the length direction of the leg 2, the side of the limiting block 4 and the limiting groove 5 is formed with an inclined surface, and the other side of the limiting block 4 and the limiting groove 5 is a plane, wherein the inclined surface of the limiting block 4 faces upwards in the vertical direction, and the inclined surface of the limiting block 4 abuts against the inclined surface of the limiting groove 5, the limiting block 4 can abut against the limiting groove 5, all sleeves 3 are provided with adjusting assemblies, the adjusting assemblies can make the limiting block 4 close to or away from the limiting groove 5, when using the product, in the initial storage state, the leg 2 is retracted into the sleeve 3, when measurement is needed, the bracket is taken out and stands on the ground, then the sleeve 3 is pulled to adjust the measurement height, in the process of pulling the sleeve 3 upwards, since the inclined surface of the limiting block 4 faces upwards in the vertical direction and the inclined surface of the limiting block 4 abuts against the inclined surface of the limiting groove 5, the inclined surface of the limiting groove 5 will push the inclined surface of the limiting block 4 away from the limiting groove 5, so that the sleeve 3 continuously rises, when the height is adjusted to the appropriate height, the sleeve 3 is no longer subjected to the pulling force, at this time, the limiting block 4 is deep into the limiting groove 5 under the action of the adjusting assembly in the height state, since the other side of the limiting block 4 and the limiting groove 5 is a plane, the limiting groove 5 cannot push the limiting block 4 away from the limiting groove 5, at this time, the plane abuts against the plane, ensuring that the sleeve 3 cannot move downwards under the abutting action of the limiting block 4 and the limiting groove 5, at this time, even if the hands forget to hold the base 1 or the sleeve 3, the height will not change suddenly, which is convenient for adjusting the height to the right place at one time.

[0025] As Figure 4As shown, the adjusting assembly includes a housing 6, a spring 7 and a pull rope 8, the housing 6 is fixedly connected with the sleeve 3, the limiting block 4 is slidingly connected with the housing 6, the spring 7 is installed between the limiting block 4 and the housing 6, one end of the pull rope 8 is fixedly connected with the limiting block 4, the other end of the pull rope 8 extends to the outside of the housing 6, when adjusting the height of the support, the limiting groove 5 of the support 2 pushes the limiting block 4 to slide, at this time, the limiting block 4 moves away from the limiting groove 5 and extrudes the spring 7 to store power, when the height adjustment is completed, the limiting block 4 is pushed into the limiting groove 5 at the corresponding height again under the restoring force of the spring 7, so that the limiting is formed and it cannot fall, when the measurement is completed, the overall height needs to be shortened for storage, the limiting block 4 is driven away from the limiting groove 5 by pulling the pull rope 8, at this time, the base 1 and the sleeve 3 can fall to shorten the overall length of the support, which is convenient for storage.

[0026] The connecting point of the pull rope 8 and the limiting block 4 of the product is at the center of the limiting block 4, this design can make the force of the limiting block 4 more balanced when pulling the pull rope 8, and the limiting block 4 will not be tilted to one side, and all the ends of the pull rope 8 extending to the outside of the housing 6 are combined into one, this design can drive all the limiting blocks 4 to move away from the limiting groove 5 at the same time when the operator pulls the combined pull rope 8, and then referring to Figure 1 As shown, the combined end of the pull rope 8 is fixedly connected with a ball head 9, the ball head 9 is convenient for the operator to hold when pulling the pull rope 8, and at the same time, the ball head 9 can also form a similar effect of a plumb bob, which is convenient for the operator to observe whether the road surface on which the support is placed is flat.

[0027] Further, the limiting block 4 and the housing 6 of the product are coated with lubricating oil, which can reduce the friction when the limiting block 4 slides back and forth, and make the use process more smooth, and then referring to Figure 4 As shown, the housing 6 is provided with an oil injection hole 10, which is convenient for subsequent addition of lubricating oil to ensure that each part of the adjusting assembly is in a good working environment.

[0028] Finally, as shown in Figure 5 The sleeve 3 is threadedly connected with a knob 11, the knob 11 can lock the sleeve 3 and the support 2, after storage is completed, the knob 11 can be used to lock the sleeve 3 and the support 2, so that they cannot slide relative to each other, and prevent misalignment during carrying.
