4. The application method of the clamp for the linear guide rail with the adjustable position comprises the following steps:
1) Left and right position adjustment of the clamp: the clamp body (1) is clamped on the outer side of a guide rail, the rotary round button (24) is pressed inwards, the connecting rod (22) moves forwards or backwards under the action of the rotary round button (24), so that the adjusting seat (17) and the rotary seat (7) are pushed to the central position of the mounting cavity (5) under the action of the connecting curved surface (25) through the positioning rod (23), the positioning rod (23) just enters the positioning groove (20) until the rotary seat (7) is not contacted with the outer limiting seat (8) or the inner limiting seat (9), the rotary round button (24) is continuously rotated, the positioning rod (23) drives the rotary seat (7) to rotate under the action of the positioning groove (20), and the adjusting rod (6) moves leftwards or rightwards under the action of threads, so that the first threaded hole (2) on the clamp body (1) is aligned with the fixing hole on the sliding platform;
2) And (3) height adjustment of the clamp: the fixing screw penetrates from a fixing hole at the upper end of the sliding platform and is in threaded connection with the inside of a first threaded hole (2) of the clamp body (1), when the fixing screw rotates downwards to a certain position, the transmission part (4-9) and the sliding block (4-8) are driven to slide downwards, so that the clamping bamboo shoots (4-10) are retracted into the shrinkage holes (4-12) from the limiting grooves (4-7), the height adjusting seat (4-2) and the positioning seat (4-1) are not synchronously rotated any more, at the moment, the nut end at the upper end of the fixing screw just contacts with the upper end face of the sliding platform, the fixing screw is continuously rotated, and the friction force to be overcome by rotating the height adjusting seat (4-2) relative to the second threaded hole (4-5) is smaller than the friction force to be overcome by rotating the fixing screw relative to the first threaded hole (2), so that the fixing screw can drive the height adjusting seat (4-2) to synchronously rotate, and the height adjusting seat (4-2) moves relative to the clamp body (1) under the action of the second threaded hole (4-5) until the clamping body (1) is not contacted with the inner side of the clamp body (1) to be stopped.
