[0025] The following will be combined with Figures 1-3 A detailed description will be given of a support frame for engineering surveying and mapping in the embodiments of this utility model.

[0026] Referring to Figures 1-2 As shown, a support frame for engineering surveying and mapping includes a hand - holding rod 1. An anti - slip sleeve 2 is arranged above the hand - holding rod 1, and the anti - slip sleeve 2 is an anti - slip silica gel sleeve. An adjusting rod 3 is inserted into the interior of the hand - holding rod 1, and a surveying and mapping instrument body 4 is threadedly connected above the adjusting rod 3. A female thread sleeve is fixed to the bottom of the surveying and mapping instrument body 4, and the female thread sleeve is threadedly connected to the upper part of the adjusting rod 3. A first fastening bolt 5 is threadedly connected to the upper part of the interior of the hand - holding rod 1, and the first fastening bolt 5 presses against the outer wall of the adjusting rod 3. Scale lines 6 for adjusting the height of the adjusting rod 3 are arranged on the adjusting rod 3.

[0027] Through the cooperation of the first fastening bolt 5 and the adjusting rod 3, the height of the surveying and mapping instrument body 4 can be adjusted, and the surveying and mapping instrument body 4 can be adjusted to the required height through the scale lines 6.

[0028] Referring to Figure 1 and 3As shown, a base 7 is fixed to the bottom end of the hand-held rod 1, and a movable sleeve 8 is movably sleeved on the hand-held rod 1. A locking bolt 9 is inserted into the movable sleeve 8, and the locking bolt 9 is threadedly connected to the inside of the hand-held rod 1. Four support rods one 10 are rotatably installed around the lower part of the movable sleeve 8, and four support rods two 11 are rotatably installed around the inside of the base 7. The support rod two 11 is rotatably connected to the support rod one 10. Installation grooves are formed at the relative positions inside the movable sleeve 8 and the base 7, and the support rod one 10 and the support rod two 11 are rotatably installed in the installation grooves. A threaded hole 15 for cooperating with the locking bolt 9 is formed above the inside of the hand-held rod 1.

[0029] By pushing the movable sleeve 8 downward, the rotational connection of the support rod one 10 and the support rod two 11 can be flipped and adjusted, so that the support rod two 11 supports on the ground. And by inserting the locking bolt 9 into the movable sleeve 8 and threadedly connecting it to the inside of the hand-held rod 1, the positions of the support rod one 10 and the support rod two 11 can be positioned, increasing the stability of the support rod one 10 and the support rod two 11 during use. By threadedly connecting the locking bolt 9 to the threaded hole 15, the support rod one 10 and the support rod two 11 can be vertically stored.

[0030] Reference Figure 1 and 3 As shown, an adjusting ring 12 is movably sleeved on the hand-held rod 1. The adjusting ring 12 is located below the movable sleeve 8. Wrench plates are fixed to the bolt heads of the fastening bolt two 13 and the locking bolt 9. A fastening bolt two 13 is threadedly connected to the inside of one side of the adjusting ring 12, and the fastening bolt two 13 presses against the outer wall of the hand-held rod 1. A positioning cone 14 is fixed to the bottom of the adjusting ring 12, and the positioning cone 14 is movably inserted into the inside of the base 7. A through hole is formed at the position of the base 7 relative to the positioning cone 14, and the positioning cone 14 is inserted into the through hole.

[0031] By pressing the adjusting ring 12 downward, the positioning cone 14 can be introduced into the ground through the through hole inside the base 7, increasing the stability of the hand-held rod 1 when supporting the total station body 4. Then, the fastening bolt two 13 can be tightened and pressed against the outer wall of the hand-held rod 1.

[0032] Advantages of this application: It is convenient to better support and use the hand-held rod 1 and the total station body 4, without the user having to hold the hand-held rod 1 for a long time, reducing the fatigue of the user's hand and not easily affecting the normal operation and use of the total station body 4.

[0033] Working principle: When adjusting the height of the total station body 4, the height of the total station body 4 can be adjusted through the cooperation of the fastening bolt one 5 and the adjusting rod 3, and the total station body 4 can be adjusted to the required height through the scale line 6.

[0034] When the hand-held rod 1 and the surveying instrument body 4 are supported and used, by pushing the movable sleeve 8 downward, the rotating connection of the first support rod 10 and the second support rod 11 can be flipped and adjusted so that the second support rod 11 supports on the ground. And by inserting the locking bolt 9 into the movable sleeve 8 and threadedly connecting it to the inside of the hand-held rod 1, the positions of the first support rod 10 and the second support rod 11 can be positioned, increasing the stability when the first support rod 10 and the second support rod 11 are used, and thus the hand-held rod 1 and the surveying instrument body 4 can be supported and used.

[0035] When enhancing the stability when the hand-held rod 1 and the surveying instrument body 4 are used, by pressing the adjusting ring 12 downward, the positioning plug cone 14 can be introduced into the ground through the through hole inside the base 7, thus increasing the stability when the hand-held rod 1 supports the surveying instrument body 4. Then, the second fastening bolt 13 is tightened and pressed against the outer wall of the hand-held rod 1.
