[0007] In a preferred embodiment, the present invention can be further configured such that: the limiting member includes a limiting screw threadedly connected to the protective sleeve, and the supporting leg is provided with a limiting groove for the limiting screw to engage with the threaded screw.

[0008] In a preferred embodiment, the present invention can be further configured such that: a guide post is fixedly connected to the inner side wall of the protective sleeve, a guide groove is provided on the support leg, and the guide post and the guide groove are slidably engaged.

[0009] In a preferred embodiment, the present invention can be further configured such that: a limiting block is fixedly connected to the bottom of the guide groove, the limiting block is located directly below the guide post, and when the guide post abuts against the limiting block, the limiting screw is aligned with the limiting groove.

[0010] In a preferred embodiment, the present invention can be further configured such that: the support leg is provided with a positioning groove, and the positioning groove is located directly above the limiting groove; when the protective sleeve moves away from the conical tip and the conical tip is completely exposed from the protective sleeve, the limiting screw can be threadedly connected to the positioning groove.

[0011] In a preferred embodiment, the present invention can be further configured such that: a positioning block is fixedly connected to the bottom of the guide groove, the positioning block is located directly above the guide post, and when the guide post abuts against the positioning block, the limiting screw is aligned with the positioning groove.

[0012] In a preferred embodiment, the present invention may be further configured such that: one of the protective covers is fixedly connected with a Velcro strap, and the Velcro strap is used to bind and secure the three protective covers together.

[0013] In summary, this utility model has the following beneficial effects:

[0014] Protective sleeves shield the tapered tips at the bottom of the support legs, reducing the risk of these tips scratching other equipment and thus mitigating the risk of damage. The sleeves are also easy to lock and unlock, significantly improving ease of operation and work efficiency. Furthermore, Velcro straps allow for the secure binding of the three sleeves, thus securing the three support legs and facilitating the transport and other operations of the tripod.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Reference Figure 1 A total station includes a total station main unit 1 and a tripod 2. The tripod 2 includes a support base 21 and three telescopic support legs 22. The total station main unit 1 is connected to the support base 21 by fastening bolts. The tops of the three support legs 22 are respectively hinged to the support base 21, and the bottoms are respectively provided with conical tips 23.

[0023] Reference Figure 1 Each support leg 22 is slidably fitted with a protective sleeve 3. A limiting member 4 is provided between the support leg 22 and the corresponding protective sleeve 3. When the protective sleeve 3 moves towards the conical tip 23 and the conical tip 23 is completely inside the protective sleeve 3, the limiting member 4 is used to fix the protective sleeve 3. At this time, the protective sleeve 3 can shield and protect the conical tip 23 at the bottom of the support leg 22, reducing the risk of the conical tip 23 scratching other equipment, thereby reducing the risk of damage to other equipment.

[0024] Reference Figure 2 , Figure 3 The limiting component 4 includes a limiting screw 41 threadedly connected to the protective sleeve 3. The support leg 22 is provided with a limiting groove 42 for the limiting screw 41 to be threadedly engaged. By screwing the limiting screw 41 into the limiting groove 42, the protective sleeve 3 can be fixed. Similarly, by screwing the limiting screw 41 out of the limiting groove 42, the protective sleeve 3 can be unlocked.

[0025] Reference Figure 2 , Figure 3 The inner wall of the protective sleeve 3 is fixedly connected to a guide post 5, and a guide groove 6 is provided on the support leg 22. The guide post 5 and the guide groove 6 are slidably engaged to allow the protective sleeve 3 to slide smoothly. A limit block 7 is fixedly connected to the bottom of the guide groove 6. The limit block 7 is located directly below the guide post 5. When the guide post 5 abuts against the limit block 7, the limit screw 41 is aligned with the limit groove 42 to facilitate the quick fixing of the protective sleeve 3 by the operator.

[0026] Reference Figure 4 , Figure 5 The support leg 22 is provided with a positioning groove 8, which is located directly above the limiting groove 42. When the protective sleeve 3 moves away from the conical tip 23 and the conical tip 23 is completely exposed from the protective sleeve 3, the limiting screw 41 can be threadedly connected to the positioning groove 8, thereby fixing the protective sleeve 3 and preventing the protective sleeve 3 from sliding when the tripod 2 is in normal use.

[0027] Reference Figure 4 , Figure 5 A positioning block 9 is fixedly connected to the bottom of the guide groove 6. The positioning block 9 is located directly above the guide post 5. When the guide post 5 abuts against the positioning block 9, the limit screw 41 is aligned with the positioning groove 8, so as to facilitate the staff to quickly fix the protective sleeve 3 and improve the ease of operation.

[0028] Reference Figure 1 One of the protective sleeves 3 is fixedly connected with a Velcro strap 10, which is used to bind and fix the three protective sleeves 3, thereby realizing the binding and fixing of the three support legs 22, which facilitates the transportation and other operations of the tripod 2 by the staff.
