Reversible wrench with fixing structure of direction switch button

Abstract

The present invention discloses a wrench which is provided with a birdirectional control button positioning structure. The wrench comprises a handle, a direction control device, a positioning device, and a connecting device. The handle is extended with a driving part that forms a driving hole. A driving piece is imbedded into the driving hole which is provided with an accommodating chamber at one side for accommodating more than one group of ratchet block. A restricting part and an accommodating part are provided adjacent to the accommodating chamber. The direction control device is provided with two reversing switches which are provided at the accommodating part and are restricted by the restricting part. The reversing switches drive the ratchet block and are respectively provided with a containing part and more than one group of positioning part. The positioning device is provided on the positioning part of the reversing switch. The connecting device comprises a connector and an elastic part. Two ends of the connector are respectively clamped on the containing part. The elastic part abuts against the connector and provides elastic force for resetting when the reversing switch is dialed to position the positioning device to the reversing switch. Therefore the purposes of fast clamping and positioning are achieved.

Description

technical field [0001] The invention relates to a wrench, in particular to a wrench with a two-way control button positioning structure, which has a fast positioning structure between two reversing switches, and cooperates with the plug-in structure between the two reversing switches and the wrench to make the two reversing switches A wrench with a two-way control button positioning structure that can be positioned immediately when the switch is inserted into the wrench and combined into one body to drive. Background technique [0002] Referring to U.S. Patent No. 6918477, it includes a wrench driving part with a direction control button at both ends, and a combination structure between the reversing switches to drive it integrally. Among them, there are many embodiments of the structure driven integrally, including: two The reversing switch has a mutual fitting structure, and is directly connected to the wrench through a through hole to form an integral driving structure.

AI Technical Summary

Problems solved by technology

[0003] 1. The complex structure of the reversing switch is difficult to form: because the reversing switch must have a relatively fitted structure, the structure of the reversing switch is very complicated, not only difficult to form, but also high in molding costs, and it is necessary to improve

[0004] 2. The stability of fitting is limited: since the reversing switch relationship is a mutual fitting structure, the strength of fitting is naturally very limited, and there will be a lack of disengagement after a slight collision, so that the overall direction control structure cannot be effective operation, affecting the service life of the overall structure

[0006] 1. The structure and combination are still complicated: because the two reversing switches still need to be fitted and set up before the screw lock, the lack of the above-mentioned fit makes the combination more complex and consumes unnecessary labor costs and combinations Structural cost, there is also a need for improvement

[0007] 2. The structure of the screw lock is highly unstable: because the place where the wrench tool is used may not only have high-frequency vibration and oil pollution, the screw lock is easily loosened due to vibration, and it is more likely to be jammed due to unnecessary pollution caused by oil pollution. When the reversing switch is damaged, it is difficult to replace it effectively and immediately, which is very inconvenient to use
