The above prior art solutions have the following drawbacks: because the theodolite is only matched with the connecting column in an inserting mode, and the dead weight of the theodolite is fixed on the disc frame, the tripod is not firm in fixing the theodolite. For example, when the workman measures the angle with the theodolite, the workman's hand can be placed on the adjustment disk of theodolite for adjust the theodolite, but at this moment the workman's hand can carry out certain little touch or empty touch between the theodolite base, and this can cause the workman hand to have the possibility of slightly colliding the theodolite base. These slight impacts may be less likely to be affected when measuring, since the worker can adjust the angle of the theodolite in real time to ensure the accuracy of the adjustment. However, after the measurement is completed, because the worker is not observing the degree of the theodolite, if the hand of the worker collides with the theodolite base at this time, the theodolite slightly deflects, and because the worker cannot find that the theodolite deflects, the measurement of the theodolite is not accurate.

The turntable 342 is further provided with a tightly-abutting elastic sheet 344, one end of the tightly-abutting elastic sheet 344 is arranged on the turntable 342, the other end of the tightly-abutting elastic sheet 344 is arranged on the pawl 343, and after the installation is completed, the tightly-abutting spring is in a compressed state and is used for tightly abutting the pawl 343 on the ratchet 341 and fixing the position of the installation seat 200 to prevent the installation seat 200 from rotating.

Referring to fig. 2 and 4, a placing groove 220 is formed in the side wall of the mounting seat 200, and a push rod 221 adapted to the arc shape of the side wall of the mounting seat 200 is hinged in the placing groove 220. In this embodiment, one end of the push rod 221 is hinged in the placing groove 220, and an elastic rubber block 222 is adhered to the side wall of the placing groove 220 near the one end to protect the push rod 221 and the side wall and prevent the side wall and the push rod 221 from being worn. And a spherical fixture block 223 is integrally arranged at the other end of the push rod 221, and the fixture block 223 is larger than the push rod 221 and is clamped with the placing groove 220 to fix the position of the push rod 221.

The working process is as follows:

when measuring, firstly, the tripod is opened, so that the three support legs 330 are erected on the ground to fix the position of the tripod, then the theodolite is placed on the mounting base 200, then the clamping block 240 is rotated, the positioning block 263 is separated from the clamping hole 264 due to the fact that the positioning block 263 is subjected to a force which is given to the positioning block 240 by the clamping block 240 and enables the positioning block to be close to the positioning groove 261, and the clamping block 240 is not fixed by the positioning block 263 any more, so that the clamping block 240 is convenient to rotate.

When the locking block 240 is located above the mounting seat 200, the worker pulls the tightening rod 242 so that the included angle between the tightening rod 242 and the hinge rod 241 becomes large, increasing the inner space of the locking groove 250. Then, the worker places the abutting plate on the upper surface of the theodolite base 100, and the abutting plate abuts the base of the theodolite on the mounting seat 200 under the action of the abutting spring, so that the theodolite is fixed.

At this time, the positioning block 263 is no longer subjected to a force which is given to the positioning block 240 by the locking block 240 and makes the positioning block 261 close to the positioning block 263, the elastic potential energy of the positioning spring 262 is released, the positioning block 263 is pushed out of the positioning groove 261, the positioning block 263 is clamped with the other clamping hole 264, the position of the locking block 240 is fixed, and the fixing firmness of the locking block 240 to the theodolite is improved.

When the measurement direction of the theodolite is to be adjusted, the worker takes out the push rod 221 from the placing groove 220 and pushes the push rod 221, and the push rod 221 abuts against one side wall of the placing groove 220 close to the hinge point, so that when the worker pushes the push rod 221, the mounting seat 200 can be pushed to rotate.

The mounting seat 200 rotates, so that the ratchet wheel 341 coaxially arranged on the mounting seat 200 rotates, and the rotating ratchet wheel 341 can generate a motion to the pawl 343 to enable the pawl 343 to approach the rotating disc 342, so that the pawl 343 does not fix the ratchet wheel 341 any more, and the mounting seat 200 is convenient to rotate. At this time, the elastic abutting piece 344 is compressed.

When the mounting base 200 does not rotate any more, the pawl 343 is no longer subjected to the movement of one of the pawls to make the pawl approach the rotating disc 342 by the ratchet 341, the elastic potential energy of the abutting elastic piece 344 is released, and the pawl 343 abuts against the ratchet 341 to fix the mounting base 200 and prevent the mounting base 200 from rotating.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
