The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Example 1
The utility model provides an anti-deflection device of laser direction appearance, includes the inspection screen 6 that is used for demarcating the light beam, the middle part of inspection screen 6 is provided with the round hole for demarcating the light beam of laser direction appearance. The installation seat 5 is installed to 6 bottoms of inspection screen, is detachable threaded connection between 6 and the installation seat 5, installs connecting rod 4 in the bottom of installation seat 5, connecting rod 4 sliding connection is in base 3, installs vertical rack 42 on one side of connecting rod 4, base 3 internal rotation is connected with the rocker 41 that the level set up, the one end of rocker 41 is located base 3 inside, is provided with gear 43 on the end of rocker 41, the one end that rocker 41 is located base 3 inside meshes with rack 42, base 3 fixed mounting is on backup pad 1. The connecting rod 4 can be moved up and down by rocking the rocking lever 41, and the height of the inspection screen 6 can be adjusted. The rocker 41 itself is connected in the base 3 in a rotating way, but the rocker 41 and the base 3 are not absolutely smooth, and a large friction force exists in the rotating process of the rocker 41, so that the friction force is not intentionally avoided, the fine adjustment is convenient (the friction force is not too small, the connecting rod 4 is also moved too much in length by light force) for improving the resistance in adjustment, and the gravity of the inspection screen 6 and the mounting seat 5 cannot overcome the friction force between the rocker 41 and the base 3 after adjustment, and the situation that the inspection screen 6 cannot be fixed due to the fact that the rocker 41 is too smooth after adjustment is avoided.
Tripod is installed to the bottom of backup pad 1, and the tripod has three telescopic link 2, is the triangle setting, and telescopic link 2 is vertical to be installed to install locking screw 21 in telescopic link 2's flexible department, the equal threaded connection in bottom of telescopic link 2 has the ground nail. In order to enable the supporting legs to adapt to various working environments during the installation of the ground nails, the stability of the ground with insufficient stability can be enhanced by the way of nailing the ground nails.

After the utility model is carelessly deviated, as the telescopic rod 2 is contacted with the ground, a force is generated, and even if the telescopic rod 2 is locked in the deviating process, the telescopic rod 2 can be relatively displaced, and the parameters of the telescopic rod 2 are unreliable. In the process of adjusting the offset utility model, the original position is only determined according to the position of the ground pin insertion mark (the position is not adjusted if the ground pin position is not offset), and the expansion degree of the expansion link 2 is readjusted according to the pressure parameter of the pressure detector 8 so as to adjust the original height and the original position according to the parameter of the electronic level meter 13. The electric push rod 7 is free from contact with the ground due to self-locking property and no stress in the use process, so that the electric push rod 7 cannot generate errors, and the parameter precision of the pressure detector 8 is absolutely larger than the precision of naked eye observation or scale observation arranged on the telescopic rod 2, so that the adoption of the pressure parameter and the parameter of the electronic level meter 13 as callback reference values has high precision and accuracy.
