Reversing device and ratchet wrench with reversing device

Abstract

A reversing device and a ratchet wrench with the reversing device, the reversing device is suitable for being installed on a handle unit of the ratchet wrench, the handle unit has a chamber surrounded by an inner wall surface, and the reversing device includes The ratchet seat, the first detent unit, the second detent unit and the reversing unit. The reversing unit is used to switch the one-way rotation direction of the ratchet seat relative to the handle unit, the reversing unit includes a reversing button, and is sandwiched between the first detent, the second An insert between the catch and the handle unit and embedded in the reversing button, the reversing button has an installation ring groove located in the chamber, and the insert is embedded in the installation ring groove And it has a side ring surface, and the side ring surface has two pushing surfaces arranged oppositely and pushing against the inner wall surface of the handle unit.

Description

technical field [0001] The present invention relates to a hand tool, in particular to a reversing device and a ratchet wrench with the reversing device. Background technique [0002] see figure 1 and figure 2 , an existing ratchet wrench 1 includes a handle body 10 , a ratchet wheel 11 , two locking units 12 , 13 , and a switch knob 14 . The handle body 10 includes a head accommodating groove 100 at the front end, and a bottom plate 101 for closing the head accommodating groove 100 , and the bottom plate 101 has a communication with the head accommodating groove 100 the connection hole 102. The ratchet wheel 11 is rotatably installed in the head accommodating slot 100 . The latching units 12 and 13 are symmetrically disposed in the head accommodating slot 100 , and each latching unit 12 and 13 has a pivotably disposed on the handle body 10 and is used for connecting with the ratchet wheel. 11 engaging catch blocks 121, 131, and a compression spring 122, 132 that spring...

AI Technical Summary

Problems solved by technology

[0004] Although the ratchet wrench 1 has the above-mentioned use effect, because the hexagonal screw 9 will be exposed on the bottom plate 101 of the handle body 10, it is not beautiful, and as time increases, the hexagonal screw 9 and the connecting hole There will also be dust stuck or rusted at the seams of 102, which will cause the problem that the switching knob 14 is stuck and cannot be moved.

In addition, when the switching knob 14 is turned, the hexagonal screw 9 will rotate simultaneously with the switching knob 14. If the hexagonal screw 9 is locked too tightly, the bolt head of the hexagonal screw 9 will be blocked. The switching knob 14 cannot be rotated because it is pressed against the bottom plate 101. If the lock of the hexagonal screw 9 is too loose, the hexagonal screw 9 will easily fall off and cannot be used. Therefore, the locking force of the hexagonal screw 9 Difficult to control when manufacturing and assembling
