[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown in the embodiment, a portable topographic mapping instrument includes a measuring instrument body 1, which is a conventional measuring instrument. A connecting frame 2 is fixedly connected to the bottom of the measuring instrument body 1. The connecting frame 2 is used to connect with a tripod or other measuring frame for convenient measurement. The measuring instrument also includes a portable frame 4 movably sleeved on the outside of the measuring instrument body 1 and two sets of portable components disposed on the portable frame 4. The portable frame 4 has a U-shaped or concave cross-section and a baffle at its tail end. Guide grooves 3 are respectively opened on both sides of the measuring instrument body 1. The portable frame 4 is sleeved on the upper part of the measuring instrument body 1. Limiting blocks 5 matching the guide grooves 3 are respectively provided on the inner walls of both sides of the portable frame 4. The limiting blocks 5 on both sides of the portable frame 4 are slidably installed in the corresponding guide grooves 3. The portable frame 4 is slidably installed onto the measuring instrument body 1 from the end away from the measuring head. The baffle is located on the measuring instrument body 1 away from the measuring head. A limiting mechanism is installed on the inner side of a baffle at one end face of the measuring head. The limiting mechanism includes a fixing groove 11 formed in the inner wall of the baffle. A first magnet 12 is fixedly connected inside the fixing groove 11. An auxiliary groove 13 is correspondingly formed on the end face of the measuring instrument body 1 away from the measuring head. A second magnet 14 is fixedly connected inside the auxiliary groove 13. After the portable frame 4 is slidably connected to the measuring instrument body 1, the first magnet 12 and the second magnet 14 attract and fix each other. By utilizing the principle of attraction between opposite poles of magnets, the portable frame 4 and the measuring instrument body 1 are magnetically fixed to each other, preventing the measuring instrument body 1 from slipping out of the portable frame 4.

[0024] In this embodiment, two sets of portable components are symmetrically arranged on the portable holder 4, such as... Figure 1 and Figure 5As shown, the outer side of the first nylon strap 6 of each portable component is fixedly connected to a Velcro surface 8, and the inner side of the second nylon strap 7 is fixedly connected to a Velcro hook surface 9. The first nylon strap 6 and the second nylon strap 7 are connected by the Velcro hook surface 9 and the Velcro surface 8. A limiting strap 10 is fitted over the second nylon strap 7, and the bottom of the limiting strap 10 is fixedly connected to the outer side of the first nylon strap 6. The measuring instrument can be fixed to the arm using the two portable components. To prevent the hard shell of the portable frame 4 from impacting the user, a cushioning foam 20 is movably connected to the top of the portable frame 4. A mesh fabric 21 is movably connected to the surface of the cushioning foam 20, and the surface of the mesh fabric 21 is fixedly connected to the top of the portable frame 4. By setting the cushioning foam 20 and the mesh fabric 21, the space between the portable frame 4 and the user's arm is filled, preventing the portable frame 4 from squeezing or impacting the user and causing injury, thus improving the comfort of carrying the measuring instrument.

[0025] In the embodiments, to avoid interference from mosquitoes, such as Figure 4 As shown, a storage slot 17 is provided on the inner side of the top of the portable holder 4. A solid insect repellent 18 is movably connected to the inside of the storage slot 17 through a non-woven fabric.

[0026] By setting up a storage slot 17 and a solid insect repellent 18, the gas generated by the volatilization of the solid insect repellent 18 repels mosquitoes, preventing users from being bothered by mosquitoes while carrying the measuring instrument. A limiting mesh plate 19 is fixedly connected inside the storage slot 17 via a snap-fit ​​structure. The top of the limiting mesh plate 19 is movably connected to the bottom of the solid insect repellent 18, and the bottom of the limiting mesh plate 19 extends to the outside of the storage slot 17. By setting up the limiting mesh plate 19, the solid insect repellent 18 is contained, preventing it from falling out of the storage slot 17. Since the limiting mesh plate 19 is fixed by a snap-fit ​​structure, it is easy for users to disassemble the limiting mesh plate 19, facilitating workers to replenish the solid insect repellent 18 into the storage slot 17.

[0027] To prevent the magnet from rusting and being damaged, such as Figure 3 As shown, a protective mechanism is provided inside the fixing groove 11. This protective mechanism includes a plastic film 15 fixedly connected inside the fixing groove 11 and located on the front side of the first magnet block 12. The front side of the plastic film 15 extends to the outside of the fixing groove 11. A waterproof membrane 16 is fixedly connected inside the auxiliary groove 13, located on the back side of the second magnet block 14. The back side of the waterproof membrane 16 extends to the outside of the auxiliary groove 13 and is movably connected to the front side of the plastic film 15. By providing the plastic film 15 and the waterproof membrane 16, the first magnet block 12 and the second magnet block 14 are protected, preventing liquid from contacting either the first magnet block 12 or the second magnet block 14, thus avoiding damage due to rust.

[0028] The working principle and usage process of this utility model are as follows: When in use, first insert the measuring instrument body 1 into the portable frame 4, so that the limiting block 5 is inserted into the guide groove 3. Then, place the portable frame 4 on the user's arm, and then pass the second nylon strap 7 through the limiting strap 10, so that the hook side 9 of the Velcro and the loop side 8 of the Velcro come into contact, thereby connecting the first nylon strap 6 and the second nylon strap 7, so that the first nylon strap 6 and the second nylon strap 7 wrap around the user's arm, and fix the portable frame 4 to the user's arm.

[0029] This utility model allows users to easily fix the measuring instrument body 1 and the carrying frame 4 to their arm. Since the measuring instrument is carried by the arm, it avoids numbness and soreness in the hand caused by carrying the measuring instrument for a long time, making the measuring instrument easy to carry.
