The bottom of the lever 82 is fixedly connected to the inner side of the top of the locking block 72. The lever 82 is set at an angle.

[0026] As a technical optimization scheme of the utility model, through setting unlocking assembly 8, when the user completes surveying and mapping work, needs first trapezoidal rod 4 and second trapezoidal rod 6 to disconnect, the carrying of support frame 1 is convenient, namely, the pull block 82 is pulled along the track of the sliding groove 81, the clamping block 72 is extracted from the groove 74, and is completely retracted into the installation groove 71, then the second trapezoidal rod 6 loses fixation, and automatically rotates and disconnects with the first trapezoidal rod 4.

[0027] Reference Figure 1 And Figure 2 The front surface of parallel block 5 is provided with fastening bolt 9, and the front surface thread of fastening bolt 9 penetrates to the front side of the inner wall of parallel block 5.

[0028] As a technical optimization scheme of the utility model, through setting fastening bolt 9, when surveying instrument 3 passes through parallel block 5, on first trapezoidal rod 4 and second trapezoidal rod 6, parallel sliding to a certain position, needs to be fixed, the operation of surveying instrument 3 is convenient for the user, namely, fastening bolt 9 is rotated until it tightly abuts against first trapezoidal rod 4 or second trapezoidal rod 6, generates abutting force, makes parallel block 5 unable to move under the action of abutting force, thereby facilitating the user to operate surveying instrument 3 to work.

[0029] Reference Figure 1 And Figure 2 The back surface of fastening bolt 9 is fixedly connected with rubber block 10, and the front surface of first trapezoidal rod 4 and second trapezoidal rod 6 is provided with friction groove 11, which is provided with a plurality of and is distributed at equal distances.

[0032] As a technical optimization scheme of the utility model, through setting the placing groove 12, the extension support leg 13 and the screw rod 14, when the first trapezoidal rod 4 and the second trapezoidal rod 6 are connected to one piece, the surveying instrument 3 is moved to the outermost distance of the second trapezoidal rod 6 through the parallel block 5, the extension support leg 13 is first rotated out of the placing groove 12, and then the screw rod 14 is rotated, until the screw rod 14 contacts the ground, so that the second trapezoidal rod 6 is supported, and the support frame 1 is prevented from collapsing together with the surveying instrument 3 when the surveying instrument 3 is moved to the outermost distance of the second trapezoidal rod 6 due to excessive center of gravity deviation.

[0033] Reference Figure 3 The outer side of the top of the clamping block 72 is inlaid with a ball 15, and the top of the ball 15 is in contact with the top of the inner wall of the groove 74.

[0034] As a technical optimization scheme of the utility model, through setting the ball 15, when the clamping block 72 is inserted into the groove 74, the ball 15 at the top of the clamping block 72 is in contact with the top of the inner wall of the groove 74, the contact area is reduced, the frictional resistance is reduced, and the clamping block 72 is prevented from being difficult to be pulled out by the pulling block 82 due to the loss of the self-vertical force of the second trapezoidal rod 6.

[0035] The working principle and use process of the utility model are as follows: when the support frame 1 is stood on the ground in use, the user adjusts the support frame 1 to be parallel to the horizontal direction, and then rotates the second trapezoidal rod 6 to be close to the first trapezoidal rod 4, after that, with the rotation of the second trapezoidal rod 6, the clamping block 72 is pressed to be shrunk into the mounting groove 71, and the spring 73 is pressed to be deformed to generate a rebound force, then when the first trapezoidal rod 4 and the second trapezoidal rod 6 are completely combined, the groove 74 is communicated with the mounting groove 71, the clamping block 72 is inserted into the groove 74 under the pushing of the rebound force of the spring 73, at this time, the clamping block 72 is in the groove 74 and the mounting groove 71 at the same time, so that the first trapezoidal rod 4 and the second trapezoidal rod 6 are stably connected, then the extension support leg 13 is rotated out of the placing groove 12, and the screw rod 14 in the extension support leg 13 is rotated until the screw rod 14 contacts the ground, so that the second trapezoidal rod 6 is supported, at this moment, the parallel block 5 can slide on the first trapezoidal rod 4 and the second trapezoidal rod 6, the surveying instrument 3 is moved out of the supporting plate 2, and the surveying instrument 3 reaches the appropriate surveying point to survey the target, so that the utility model has the advantages of assisting parallel movement.

[0036] In summary: the surveying support frame with parallel adjustable position, through setting the first trapezoidal rod 4 and the second trapezoidal rod 6, when the user stands the support frame 1, makes the supporting plate 2 level, needs the surveying instrument 3 parallel out of the supporting plate 2, carries out surveying to the target point, utilizes the fixed connection mechanism 7, makes the first trapezoidal rod 4 and the second trapezoidal rod 6 splice in a piece, forms a complete path, and then can supply the parallel block 5 to drive the surveying instrument 3 parallel movement, solves some surveying points only in the specific position, can just stand the support frame, adjusts the supporting plate to the horizontal state, however when the target point to be surveyed by the surveying instrument, in the measurement process, just shifts in the horizontal direction, cannot carry out normal surveying, the support frame cannot move, can only let the surveying instrument parallel, but the above equipment lacks the independent parallel movement structure of the surveying instrument.
