Detailed Description
As shown in figures 1 and 2, the multipurpose ratchet wrench comprises two ratchets 1 with different sizes, a connecting mechanism for simultaneously and fixedly connecting the two ratchets 1 and a reversing mechanism for adjusting the rotating direction of the ratchets 1, wherein the connecting mechanism comprises two pressing plates 3 which are arranged in bilateral symmetry and a clamping plate 6 fixed between the two pressing plates 3, the two ratchets 1 are respectively fixed at the front end and the rear end of the clamping plate 6 through the pressing plates 3, the reversing mechanism comprises two groups of reversing components respectively matched with the two ratchets 1, each reversing component comprises a plectrum 2 partially meshed with the outer edge of the ratchet 1, a steel ball 4 for jacking the plectrum 2 and an adjusting spring 5 matched with the steel ball 4, the plectrum 2 can be clamped between the ratchet 1 and the clamping plate 6 in a shifting manner, the steel ball 4 and the adjusting spring 5 are both fixed in the clamping plate 6 at positions close to the plectrum 2, the adjusting spring, the middle parts of the front end and the rear end of the clamping plate 6 are respectively provided with a groove 61 for accommodating the steel ball 4 and the adjusting spring 5.
The ratchet wheel 1 is of a circular structure, and pawls 11 are regularly and annularly distributed on the outer edge of the ratchet wheel 1. The upper end and the lower end of one side of the plectrum 2 close to the ratchet 1 are respectively provided with a plectrum claw 21 meshed with the pawl 11, and the middle part of one side of the plectrum 2 close to the steel ball 4 is provided with a bulge 22 used for being pressed against the steel ball 4.
The center of the plectrum 2 is provided with a rivet 7, and the plectrum 2 can be clamped between the ratchet 1 and the clamping plate 6 through the rivet 7 in a poking way. The clamping plate 6 and the shifting sheet 2 are both fixed with the pressing plates 3 at two sides through rivets 7.
In the actual operation process, the left shifting piece is shifted, so that the upper-end shifting piece claw 21 of the left shifting piece 2 is meshed with the pawl 11 of the ratchet wheel 1, and when the bulge 22 of the left shifting piece 2 is positioned above the steel ball 4, the ratchet wheel 1 on the left side can rotate anticlockwise; when the right shifting piece is shifted, the upper-end shifting piece claw 21 of the right shifting piece 2 is meshed with the pawl 11 of the ratchet wheel 1, and the bulge 22 of the right shifting piece 2 is positioned above the steel ball 4, the right ratchet wheel 1 can rotate clockwise.
