Detailed Description
The following is a further detailed description of the embodiments:
As shown in fig. 1 to 3:
The crescent open-end wrench comprises a wrench body formed by fixedly connecting a handle 1 and an arc-shaped guide rail 2, wherein the handle 1 is fixedly connected with the end part of the arc-shaped guide rail 2, an installation groove 5 for installing a buffer block 6 is formed in the connection part of the handle 1 and the arc-shaped guide rail 2, and the buffer block 6 is fixedly installed in the installation groove 5 and used for abutting against the side wall of a pipe fitting to prevent the wrench body from extruding the surface of the pipe fitting; the telescopic joint module of adjustable working length is installed to arc guide rail 2 department, telescopic joint module comprises telescopic link 7, jack catch 8 and screw rod 9, telescopic link 7 is the arc structure, it is with the guide slot 3 adaptation in the arc guide rail 2, telescopic link 7 inserts to the guide slot 3 from the tip of arc guide rail 2, screw rod 9 passes through threaded connection with telescopic link 7, the tip of screw rod 9 is provided with knob 10, screw rod 9 is located spout 4 departments, through fastening screw rod 9 for knob 10 and telescopic link 7 centre gripping are in the both sides of spout 4, and then fix telescopic link 7, the inboard that telescopic link 7 is located the outer one end of arc guide rail 2 is provided with jack catch 8, jack catch 8 is used for the joint at draw-in groove or the protruding department of pipe fitting, the arc both ends extension line of arc guide rail 2 can't constitute circularly, the arc of arc guide rail 2 and extension line are the heliciform.
The buffer block 6 is made of silica gel or rubber, and the buffer block 6 has certain elasticity, so that the too hard wrench body with excessive hardness is avoided, and the wrench body is extruded and damaged.
A reinforcing rib plate is arranged between the arc-shaped guide rail 2 and the handle 1, and the reinforcing rib plate is used for reinforcing the connection strength between the handle 1 and the arc-shaped guide rail 2.
