Firstly, an operator moves the device to a designated position in a tunnel, then the photogrammetric instrument is placed on the placing plate 8, due to the weight of the photogrammetric instrument, the photogrammetric instrument drives the placing plate 8 to move downwards, the placing plate 8 moves downwards to drive the movable slide rod 7 to move downwards, the first spring 9 is compressed, meanwhile, the placing plate 8 and the movable slide rod 7 move downwards and also drive the fixing device 10 to operate, and further when the fixing device 10 does not fix the photogrammetric instrument, the operator can manually pull the movable slide rod 7 to move downwards, when the fixing device 10 continues to operate to fix the photogrammetric instrument, the movable slide rod 7 is stopped being pulled, meanwhile, the fixing device 10 also fixes the movable slide rod 7, then the twisting fastening bolt 5 rotates reversely and moves rightwards, the fastening bolt 5 moves rightwards without contacting with the fixed slide rod 2, the twisting fastening bolt 5 is stopped, namely, the round rod 3 can be pulled to move upwards and, round bar 3 reciprocates and just also reciprocates through fixing device 10 drive movable slide bar 7, movable slide bar 7 drives photogrammetric instrument through placing board 8 and reciprocates, photogrammetric instrument reciprocates when suitable use height, stop pulling round bar 3, wrench movement fastening bolt 5 corotation is removed left and is contacted with fixed slide bar 2, fastening bolt 5 just also cooperates with fixed slide bar 2 with round bar 3 fixed, stop wrench movement fastening bolt 5 afterwards, can begin to measure tunnel length with photogrammetric instrument, then need not the people and hold photogrammetric instrument and measure tunnel length, the arm achinery that has avoided influences work efficiency. When the photographic measuring instrument needs to be moved to another position to measure the length of the tunnel, the device can be lifted and moved to the next position. After tunnel length measurement is accomplished, fixing device 10 can be operated and movable slide bar 7 is loosened, because of the effect of first spring 9, movable slide bar 7 moves upward and drives and places board 8 rebound, place board 8 rebound and drive photogrameter rebound, simultaneously, place board 8 and still drive fixing device 10's partial part rebound, and then when placing board 8 rebound to the normal position, fixing device 10 then loosens the photogrameter, operating personnel can take off the photogrameter from placing board 8.

When the photogrammetric instrument is placed on the placing plate 8, due to the action of the third spring 1010, the movable slide rod 7 moves downwards to drive the fixture block 109 to move downwards, meanwhile, the placing plate 8 moves downwards to drive the sliding plate 102 to move downwards, the sliding plate 102 moves downwards to drive the fixing plate 104 to move downwards, the sliding plate 102 also drives the connecting rod 105 to move downwards, the connecting rod 105 moves downwards to drive the guide wheel 106 to move downwards, the guide wheel 106 moves downwards to roll in the conical ring 107, and then the conical ring 107 enables the guide wheel 106 moving downwards to move inwards, the guide wheel 106 moves inwards to drive the connecting rod 105 to move inwards, the connecting rod 105 moves inwards to drive the sliding plate 102 to move inwards, the second spring 103 compresses, the sliding plate 102 moves inwards to drive the fixing plate 104 to move inwards, when the fixing plate 104 moves inwards and is not contacted with the photogrammetric instrument, an operator can pull the movable slide rod 7 to move downwards by hand, therefore, the fixing plate 104 continues to move inwards, when the fixing plate 104 moves inwards to contact with the photogrammetric instrument to fix the photogrammetric instrument, the movable slide rod 7 stops being pulled, and due to the action of the third spring 1010, the fixture block 109 is clamped into the fixture hole 1011 to fix the movable slide rod 7, so that the measurement of the tunnel length can be started. After the tunnel length measurement is completed, the rubber sheet 1013 is pushed by hand to move inwards, the fourth spring 1014 is compressed, the rubber sheet 1013 moves inwards to drive the push rod 1012 to move inwards, the push rod 1012 moves inwards to push the fixture block 109 to move inwards, the third spring 1010 is compressed, the fixture block 109 moves inwards to be separated from the fixture hole 1011, due to the action of the first spring 9, the movable slide rod 7 moves upwards to drive the placing plate 8 to move upwards to reset, the guide wheel 106 is also driven to move upwards, due to the action of the second spring 103, the slide plate 102 moves outwards to drive the fixing plate 104 to move outwards to reset, the fixing plate 104 releases the photogrammetric instrument, meanwhile, the slide plate 102 also drives the guide wheel 106 to reset through the connecting rod 105, the movable slide rod 7 also drives the fixture block 109 to move upwards to reset, then the rubber sheet 1013 is released, due to the action of the fourth spring 1014, the rubber sheet 1013 moves outwards to drive the push rod 1012 to move outwards to reset, the fixture block, due to the action of the third spring 1010, the latch 109 moves outward and is inserted into the latch hole 1011, and the operator can take down the surveying instrument from the placing plate 8.

Initially, the sixth spring 1110 is in a stretched state, when the photogrammetric instrument needs to be moved to another designated position to measure the length of the tunnel, the circular ring plate 113 can be stepped on by feet, the circular rod 3 is pulled to move upwards, the circular rod 3 moves upwards to drive the fixed slide rod 2 to move upwards through the fastening bolt 5, the fixed slide rod 2 moves upwards to drive the base 1 to move upwards, the fifth spring 114 is compressed, the base 1 moves upwards to be separated from the ground, the universal wheel 116 is also contacted with the ground, the fixed slide rod 2 moves upwards and also drives the slot 1111 to move upwards, the slot 1111 moves upwards to correspond to the catch rod 118, due to the action of the sixth spring 1110, the pull ring 119 moves inwards to drive the catch rod 118 to move inwards, the catch rod 118 moves inwards to be inserted into the slot 1111, the catch rod 118 is matched with the slot 1111 to fix the fixed slide rod 2, the base 1 is fixed, and the feet are put down from the circular ring plate 113, the universal wheel 116 can push the device to drive the photogrammetric instrument to move to another specified position. When the photogrammetric instrument moves to another assigned position, can stop promoting this device, pulling pull ring 119 outwards removes, sixth spring 1110 is tensile, pull ring 119 outwards removes and drives kelly 118 outwards removal, kelly 118 outwards removes and breaks away from with slot 1111, because of the effect of this device gravity, fixed slide bar 2 drives base 1 and moves down and resets, fifth spring 114 just also resets, base 1 then contacts with ground, fixed slide bar 2 still drives slot 1111 and moves down and resets, loosen pull ring 119 afterwards, can continue to use the photogrammetric instrument to measure tunnel length. Therefore, the device is more convenient for an operator to move the photogrammetric instrument through the device.

When the fixing plate 104 fixes the photogrammetric instrument, an operator can twist the screw 17 to move inwards, the screw 17 moves inwards to push the rubber plate 16 to move inwards, the rubber plate 16 moves inwards to drive the slide block 14 to move inwards, the seventh spring 15 is compressed, the rubber plate 16 moves inwards to contact with the photogrammetric instrument to fix the photogrammetric instrument, and the screw 17 is stopped being twisted. When the fixing plate 104 moves outward to release and reset the photogrammetric instrument, the operator can twist the screw 17 to move outward, and due to the action of the seventh spring 15, the sliding block 14 moves outward to drive the rubber plate 16 to move outward to reset, so that the twisting of the screw 17 can be stopped. Therefore, the photographic measuring instrument can be fixed more stably.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
