Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Referring to Figures 1-4, the utility model provides a portable map drawing tool for surveying and mapping, including a device body 1, a pull-out box 2 is arranged inside the device body 1, and the pull-out box 2 passes through the front surface of the device body 1, a locking mechanism 3 is arranged at the connection between the pull-out box 2 and the device body 1, and a protective mechanism 5 is arranged on the top of the device body 1;

[0026] The protection mechanism 5 includes a protection plate 51 and a groove 52. The number of the protection plates 51 is two, and the protection plates 51 are arranged in a mirror-symmetrical manner. A groove 52 is arranged on the top of the protection plate 51, and a handle 53 is arranged inside the groove 52. Connecting rods 54 are symmetrically arranged on both sides of the protection plate 51. A first clamping hole 510 is arranged on one side of the connecting rod 54, and a second clamping hole 59 is arranged on the other side of the first clamping hole 510. A spring protrusion 511 is clamped inside the first clamping hole 510, and an inner rod 512 is arranged on the outer side of the spring protrusion 511. An anti-slip pad 513 is arranged at the bottom of the inner rod 512. A fixing bolt 55 is arranged through the internal thread of the connecting rod 54, and a sliding groove 56 is arranged on one side of the connecting rod 54. A first fixing hole 57 is arranged inside the sliding groove 56, and a second fixing hole 58 is arranged on the other side of the first fixing hole 57.

[0027] When in use, rotate the fixing bolt 55 to loosen the fixation on the first fixing hole 57, and then use the handle 53 to pull the protection plate 51 along the slide groove 56 to the side away from the device body 1. After moving to the other end point of the slide groove 56, turn the protection plate 51 ninety degrees, and then rotate the fixing bolt 55 to insert into the second fixing hole 58 for fixation. Finally, press the spring protrusion 511 inside the first clamping hole 511 to allow the inner rod 512 to be pulled outward until the spring protrusion 511 is clamped and fixed with the second clamping hole 59, so that the top of the device body 1 can be used for drawing normally.

[0028] The locking mechanism 3 includes a buckle groove 33 and a flip groove 34. The flip groove 34 is arranged on one side of the buckle groove, and a fixing groove 35 is arranged above the flip groove 34. A rotating rod 32 is arranged inside the flip groove 34, and a flip plate 31 is arranged on the outside of the rotating rod 32. By buckling the flip plate 31, the pull-out box 2 is pushed back into the inside of the device body 1, and then the flip plate 31 is released, and then the flip plate 31 is pushed back by the rebound of the torsion spring to be locked.
