摘要： The present invention relates to the technical fields of automobile maintenance and device calibration, and discloses a calibration device, the calibration device comprising: a laser assembly; a calibration bracket, comprising a loading platform, the loading platform being used for supporting the laser assembly; and a magnetic element, mounted on one of the laser assembly and the loading platform, and being used for attracting the other of the laser assembly and the loading platform. By means of arranging the magnetic element on one of the loading platform and the laser assembly, the magnetic element can attract the other of the loading platform and the laser assembly, so that when the laser assembly needs to be mounted on the loading platform, the laser assembly only needs to approach the loading platform and the laser assembly will be attracted to the loading platform due to the magnetic force provided by the magnetic element and, when the laser assembly needs to detach from the loading platform, the laser assembly only needs to be subjected to force to overcome the magnetic force provided by the magnetic element in order to separate the laser assembly from the loading platform, making detachment of the laser assembly and the calibration bracket convenient.

摘要： Embodiments of the disclosure discloses a calibration bracket. The calibration bracket includes a base, a vertical rod, a transverse force application member and a transverse force application mating member. The vertical rod is detachably mounted to the base. The transverse force application member is disposed on one of the base and the vertical rod. The transverse force application mating member is disposed on the other of the base and the vertical rod and is configured to be connected to the transverse force application member to apply, to the vertical rod, a force parallel to the base. A limiting protrusion is provided on one of the base and the vertical rod. A limiting opening is provided on the other of the base and the vertical rod. The limiting opening can allow the limiting protrusion to pass through the limiting opening and snugly abut against the limiting protrusion when the transverse force application member applies a transverse force to the vertical rod. By means of the structure described above, the vertical rod can be quickly mounted to or detached from the base. Therefore, the calibration bracket is easy to assemble and transport.

摘要： Embodiments of the present invention disclose a two-line laser emitter. The two-line laser emitter includes a housing, a laser emitter base mounted inside the housing, an elastic clamping member, a laser emitter and a pair of rotation adjustment screws. The laser emitter base has a laser emitter mounting hole. The elastic clamping member is mounted in the laser emitter mounting hole. The laser emitter is mounted in the laser emitter mounting hole, and one end of the laser emitter is inserted into the elastic clamping member. The laser emitter is configured to emit a planar ray of light out of the housing. A pair of rotation adjustment screws are disposed in the laser emitter base and located on the same side of a central axial plane of the laser emitter. The pair of rotation adjustment screws abut against a side wall of the laser emitter in opposite directions on the same straight line. Each of the rotation adjustment screws is adjustable to slightly adjust a rotation angle of the planar ray of light emitted by the laser emitter. By means of the structure described above, emission angles of different laser emitters can be adjusted by using the two-line laser emitter, thus helping users perform self-calibration.
