According to the technical scheme, the motor drives the transmission gear to rotate, the transmission gear drives the pinion to rotate, the pinion drives the threaded sleeve to rotate in the bearing, and at the moment, the threaded rod rotates in the threaded sleeve to convert rotary motion into linear lifting motion, so that the effect of adjusting the height of the clamping mechanism is achieved.
Further, the lifting mechanism is provided with four groups and is arranged in a rectangular shape, and the transmission gear and the four pinions are all meshed.
According to the technical scheme, the stability and the supporting force of the lifting seat during lifting are improved through the four groups of lifting mechanisms.
Further, the threaded rod is made of high-strength steel.
According to the technical scheme, the strength of the threaded rod is improved through the high-strength steel, the service life is prolonged, and meanwhile the problem that the lifting seat cannot be supported due to insufficient strength is avoided.
Further, the fixed block is fixed on the side wall of the fixed seat.
According to the technical scheme, the fixing block is used for fixing the fixing seat, so that the whole bench clamp is stable.
Further, the fixing blocks are arranged at four corners of the fixing seat and are made of high-strength steel materials.
According to the technical scheme, the strength of the fixing block is improved through the high-strength steel material, so that the fixing stability is improved.
Compared with the prior art, the bench clamp has the advantages that the lifting device is arranged, the height can be adjusted according to the demands of operators, the adaptability of the bench clamp is improved, the long-term bending work of the operators is avoided, and the use convenience of the bench clamp and the use experience of the operators are greatly improved.
