[0025] As Figures 1 to 3 shown, the transfer box 101 is slidably mounted with a plurality of support frames 201, the transfer box 101 is rotatably mounted with a plurality of adjusting lead screws 202, the adjusting lead screws 202 are connected with the support frames 201 through the thread, the support frames 201 are rotatably mounted with main legs 203, one side of the support frames 201 is rotatably mounted with tension knobs 204, the tension knobs 204 are connected with the main legs 203 through the thread, the tension knobs 204 are used to control the tightness of the main legs 203 when rotating, when the tension knob 204 is rotated, the tension knob 204 is moved away from the main leg 203, then the rotation of the main leg 203 will not be limited, on the contrary, when the tension knob 204 moves close to the main leg 203, the tension knob 204 will increase the adhesion of the support frame 201, so as to limit the rotation of the main leg 203 by increasing the friction.

[0026] As Figures 2 to 8 shown, the main leg 203 is slidably mounted with an intermediate slide rod 205, one side of the intermediate slide rod 205 is provided with a plurality of clamping grooves, the intermediate slide rod 205 is slidably mounted with a bottom leg 206, one end of the bottom leg 206 is fixedly installed with a tapered cylinder 207, the tapered cylinder 207 is used to penetrate into the soil, one side of the bottom leg 206 is provided with a plurality of limiting grooves, the main leg 203 is slidably mounted with a pressing block button 208, the pressing block button 208 is fixedly installed with a pressing spring, the other end of the pressing spring is arranged on the main leg 203 to reset the pressing block button 208, the pressing block button 208 is slidably mounted with an indirect block 209, the indirect block 209 is fixedly installed with a compensation spring, the other end of the compensation spring is arranged on the pressing block button 208, the indirect block 209 is fixedly installed with a main extrusion rod 210, one end of the main extrusion rod 210 away from the indirect block 209 is provided with an extrusion inclined surface.

[0027] AsFigures 2 to 9 As shown, a main clamping block 211 is slidably installed on the main support leg 203, and the main clamping block 211 contacts the main extrusion rod 210. The main extrusion rod 210 is used to squeeze the main clamping block 211 to move, and one end of the main clamping block 211 is fixedly installed with a main spring 212, and the other end of the main spring 212 is fixedly installed on the outer wall of the main support leg 203. The main clamping block 211 fits in the positioning groove on the middle slide bar 205, and a secondary clamping block 215 is slidably installed on the middle slide bar 205. A secondary spring 216 is fixedly installed on the secondary clamping block 215, and the other end of the secondary spring 216 is fixedly connected to the outer wall of the bottom support leg 206, and the secondary clamping block 215 fits in the limiting groove on the bottom support leg 206.

[0028] Working principle: When the device is in use, Figure 1 The figure shows the transport state, in which the surveying equipment is prevented from being stored in the rotating shell 102. When the surveying equipment is placed in the rotating shell 102, it is necessary to connect the surveying equipment to the mounting platform 106 to prevent the surveying equipment from colliding with the inner wall of the rotating shell 102 during transportation, thereby damaging the surveying equipment.

[0029] After the device is moved to the position to be surveyed, the tension knob 204 can be turned to move the tension knob 204 away from the main leg 203, and then the main leg 203 can be turned again to rotate the main leg 203 between one hundred and thirty and one hundred and eighty degrees. In this way, the multiple main legs 203 outside the transfer box 101 are rotated. At this time, the user can press the block button 208 to drive the secondary extrusion rod 214 to move first, and then the secondary extrusion rod 214 will squeeze the secondary block 215 to move away from the bottom leg 206, so that the secondary block 215 can fit into the limit groove on the bottom leg 206. At this time, the bottom leg 206 can slide on the middle slide bar 205. It is worth noting here that the block button When 208 drives the secondary extrusion rod 214 to move, the pressure block button 208 will also press the indirect block 209, but at this time the compensation spring is compressed in advance, so the main extrusion rod 210 will not be driven at this time. Only when the user presses the pressure block button 208 hard to move the pressure block button 208 to a position close to the main support leg 203, the indirect block 209 will squeeze the main block 211 through the main extrusion rod 210, so that the main block 211 is out of contact with the positioning groove on the middle slide bar 205. At this time, the middle slide bar 205 can slide on the main support leg 203, so after the user presses the pressure block button 208 hard, the bottom support leg 206 and the middle slide bar 205 can be extended downward by gravity until the cone 207 contacts the ground and penetrates a certain depth into the ground.

[0030] The status of the device at this time is as follows Figure 9In the shown state, the rotating shell 102 can be opened, and then the adjusting handle 103 on the transfer box 101 is rotated, the adjusting handle 103 drives the lifting screw 105 to rotate, and then the lifting screw 105 drives the installation platform 106 to move away from the transfer box 101, so that the surveying equipment is moved away from the transfer box 101, and the surveying equipment is arranged. Then, the state of the installation platform 106 and the transfer box 101 is adjusted to be horizontal according to the level on the installation platform 106. The adjusting process is that the user rotates the adjusting screw 202, the adjusting screw 202 drives the support frame 201, and the support frame 201 slides up and down outside the transfer box 101. When the device is transferred, the intermediate slide rod 205 and the bottom support leg 206 can not be retracted. Only the installation platform 106 is retracted into the transfer box 101 by rotating the adjusting handle 103, and then the rotating shell 102 is closed to protect the surveying equipment. Then, the device can be transferred without disassembling the surveying equipment.

[0031] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
