[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surveying and mapping operation wrench, comprising a handle and a wrench head, a shovel head is arranged on the top of the handle, a slot matching the shovel head is opened on the inner side of the wrench head, insertion holes are opened on the top and bottom of both ends of the handle, and buckle plates are arranged in the middle of both ends of the bottom of the wrench head, two groups of the buckle plates are provided with sleeves at one end away from each other, the inner sides of the two groups of the sleeves are slidably inserted with insertion rods matching the insertion holes, and the outer sides of the two groups of the insertion rods are sleeved with springs.

[0008] Preferably, a pentagonal hole and a hexagonal hole are respectively provided on both sides of the wrench head, so that the device can be used to disassemble and assemble pentagonal nuts and hexagonal nuts, thereby improving the scope of use.

[0009] Preferably, an arc groove matching the wrench head is provided on the top of the handle, thereby improving the limiting effect of the handle.

[0010] Preferably, a pull ring is provided at one end away from the two groups of insertion rods to facilitate the operation of disassembling the wrench head.

[0011] Preferably, the buckle plate is in an arc shape, and is matched with the handle, thereby improving the fixing effect on the wrench head.

[0012] Preferably, a limiting ring is provided in the middle of the outer side of the two groups of the insertion rods, and the two groups of the springs are connected to the limiting ring on one side close to each other. The limiting ring can limit the range of motion of the insertion rod and push the two groups of springs to compress when the insertion rod is pulled.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the surveying and mapping operation wrench, through the mutual cooperation between the wrench head, the shovel head, the slot, the buckle plate, the spring, the sleeve, the socket and the insertion rod, makes the device not only be used for disassembly and assembly of pentagonal nuts and hexagonal nuts when in use, but also can be used for soil excavation and detection in surveying and mapping projects by removing the wrench head from the outside of the shovel head and buckling it into the bottom of the handle. At this time, the shovel head is exposed to the outside and can be used for soil excavation, thereby increasing the scope of use of the device, and when the wrench head is buckled into the outside of the shovel head, the connection strength of the wrench head can be strengthened, thereby improving its rotation stability.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] See also Figure 1-7 The embodiment of the utility model provided is a surveying and mapping operation wrench, comprising a handle 1 and a wrench head 3, two sides of the wrench head 3 are respectively provided with a pentagonal hole 2 and a hexagonal hole 6, so that the device can disassemble and assemble the pentagonal nut and the hexagonal nut, thereby improving the scope of use. A shovel head 4 is arranged on the top of the handle 1, and a slot 5 matching the shovel head 4 is arranged on the inner side of the wrench head 3. Plug holes 10 are arranged on the top and bottom of both ends of the handle 1, and a buckle plate 7 is arranged in the middle of both ends of the bottom of the wrench head 3. A sleeve 9 is arranged at one end away from the two groups of buckle plates 7. A plug rod 11 matching the plug hole 10 is slidably inserted into the inner side of the two groups of sleeves 9. A spring 8 is sleeved on the outer side of the two groups of plug rods 11. A limiting ring is arranged in the middle of the outer side of the two groups of plug rods 11. The two groups of springs 8 are connected to the limiting ring on one side close to each other, and the range of motion of the plug rod 11 can be limited by the limiting ring, and the two groups of springs 8 are pushed to compress when the plug rod 11 is pulled.

[0024] Furthermore, an arc-shaped groove matched with the wrench head 3 is provided on the top of the handle 1 , so that the wrench head 3 can be perfectly inserted into the top of the handle 1 , thereby improving the limiting effect of the handle 1 .

[0025] Furthermore, a pull ring is provided at one end of the two groups of insertion rods 11 which are far away from each other, and the insertion rods 11 can be pulled by the pull ring, so as to facilitate the operation of disassembling the wrench head 3.

[0026] Furthermore, the buckle plate 7 is arc-shaped, and the buckle plate 7 is adapted to the handle 1 , so that the buckle plate 7 can be inserted into the outer side of the handle 1 , thereby improving the fixing effect on the wrench head 3 .

[0027] Working principle: During surveying and mapping operations, the pentagonal nut can be disassembled and assembled through the pentagonal hole 2, and the hexagonal nut can be disassembled and assembled through the hexagonal hole 6. When in use, the pentagonal hole 2 or the hexagonal hole 6 can be inserted into the outside of the nut and then the handle 1 can be rotated for disassembly and assembly;

[0028] When the soil needs to be excavated and tested during the surveying and mapping operation, the two groups of plug rods 11 can be pulled out of the insertion hole 10 by pulling the pull ring to overcome the elastic force of the spring 8, and then the wrench head 3 can be pulled out from the outside of the shovel head 4, and then the wrench head 3 can be inserted into the bottom of the handle 1, so that the two groups of plug rods 11 are stuck in the two groups of insertion holes 10 at the bottom for fixing, and the shovel head 4 can be used for excavation and testing of the soil. When using it, the operator can hold the wrench head 3 as a handle;

[0029] After being used for soil excavation, the wrench head 3 can be inserted into the outer side of the shovel head 4 on the top of the handle 1 again, and the shovel head 4 can strengthen the fixation of the wrench head 3.
