Thus, the hand tool may utilize the second sleeve member to be corresponded to the different sizes of unloading mouths causing quantity requirement, so that the number of the first sleeve members and the wrench member may be reduced to avoid waste and easy for use and storage.

Description

Hand tool

The present invention relates to vehicle warranty tools, and more particularly to a hand tool.

In the technology disclosed in Japanese Patent No. I496708, there is disclosed a mouthpiece kit tool for wearing on a bleeder for facilitating the operation of the mouthpiece, but due to different brands and models. The different nozzles, especially the difference in size, make the single-mouth nozzle kit tool not suitable for the rotation of different size nozzles. Therefore, for the operator, most of the different sizes of the nozzle kit are available. The tool is required for the job.

In the technical content disclosed in the above patent application, the wrench for providing the rotating arm is integrated with the sleeve for socketing on the nozzle, so that the number of the wrench is the same as the number of the sleeve, but The wrench is not as varied as the sleeve depending on the size of the nozzle. Therefore, the number of wrenches with the same number of sleeves is an unnecessary waste, which is not ideal.

Accordingly, it is a primary object of the present invention to provide a hand tool that can be used to form an arm of a force applying arm that can be combined with a plurality of components for use with a mouthpiece to reduce the number of tools and avoid waste. Easy to use and store.

In order to achieve the above object, the hand tool provided by the present invention comprises a wrench and a first kit and a second kit, wherein the first kit is used as the wrench and the second kit. a transmission component, and the second kit acts as a transmission component between the first kit and the nozzle, and the second kit is selectively snapped or separated from the first kit, thereby making the hand tool only The second kit is required to have a large number of requirements depending on the size of the nozzle, and the number of the first kit and the wrench can be reduced, thereby achieving the effect of avoiding waste and being easy to use and store.

Further, the first kit has a tubular first body portion, an outer tube connecting portion is disposed at one end of the tube shaft of the first body portion, and a first card portion is coupled to the first body portion The other end of the tube shaft is disposed on a circumferential side of the first body.

The second set has a tubular second body coaxial with the first body and is axially displaceable between a combined position and a separate position. When in the coupled position, the tube shaft is One end is coaxially inserted into the other end of the tube shaft of the first body portion, and when located at the separated position, one end of the tube shaft is separated from the first body portion and separated therefrom, and a third card portion is coupled to One end of the tube shaft of the second body portion, and when the second body portion is located at the joint position, is engaged with the first card portion, and a mouthpiece portion is disposed on the tube of the second body portion The other end of the shaft.

The wrench has a set of parts that are restrained to be slidably coupled to the first body and to be engaged with the second card portion, and an arm extends outwardly from the sleeve.

Additionally, to facilitate positioning of the second set in the engaged position, the first set further includes a positioning portion for providing positioning of the second set.

In order to facilitate the detachment of the second sleeve from the binding position, the positioning portion provides elastic positioning to the second sleeve. Specifically, the source of elasticity is in addition to the permeable material, and is also transparent to the structure. The former may be a continuous ring-shaped elastic ring such as a rubber ring, and the latter may be a non-continuous ring-shaped elastic ring like a C-ring.

The elastic ring is coaxially disposed on the wall of the tube hole of the first body and sleeved on one end of the tube shaft of the second body at the bonding position.

The second kit includes an annular positioning groove recessed on the circumferential side annular surface of one end of the second body tube shaft, and is engaged with the elastic ring at the bonding position.

In order to prevent the elastic ring from being displaced by the axial displacement of the second set, the positioning portion further includes an annular recessed groove coaxially disposed on the wall of the tube hole of the first body portion. For the elastic ring to be embedded.
