The drill bit is used for punching, the function is single, and when in construction, not only the drilling is needed, but also a screwing tool such as a screwdriver is probably needed, and the screwdriver and the drill bit are two tools which are not related to each other, and if the structure of the drill bit can be slightly improved and the drill bit can be used as a screwdriver, the improvement is an innovative improvement.

SUMMERY OF THE UTILITY MODEL

The utility model provides a bit connects pole combination tool.

The drill bit and connecting rod combined tool comprises a drill bit, wherein the drill bit consists of a head part, a connecting part and a handle part which are integrally connected, the connecting part is a hexagonal prism, the drill bit further comprises a connecting rod assembly, the connecting rod assembly consists of a connecting rod and a screwing tool, one end of the connecting rod is provided with an inner hexagonal connecting rod corresponding to the connecting part, and the other end of the connecting rod is connected with the screwing tool.

Preferably, the connecting portion is provided with an annular groove, the extension rod is provided with a plurality of bayonets corresponding to the annular groove, elastic components are arranged in the bayonets, and the elastic components are clamped in the annular groove under elastic acting force.

Preferably, the elastic component is a marble and a compression spring arranged on the marble.

Preferably, the resilient member is a circlip.

Preferably, one end of the connecting rod is provided with a slot, and the screwing tool is connected in the slot through magnetic adsorption.

Preferably, the lower half part of the screwing tool is a hexagonal prism, and the slot of the extension rod is an inner hexagonal.

The improvement can match the drill bit and the connecting rod to be used as a screwing tool, and only the screwing tool with different specifications needs to be replaced, so that the carrying of the matching tool is reduced, and the use is convenient.

Detailed Description

The present invention will be further explained with reference to the following examples in conjunction with the accompanying drawings.

Referring to fig. 1 to 4, the combined tool for a drill and a extension rod comprises a drill 10 with a limit stop function and an extension rod assembly, wherein the drill 10 comprises a head 11, a connecting part 12 and a handle 13 which are integrally connected, the connecting part 12 is a hexagonal prism, the extension rod assembly comprises an extension rod 20 and a screwing tool 30, one end of the extension rod 20 is provided with an inner hexagonal extension rod 21 corresponding to the connecting part 12, the other end of the extension rod is provided with a slot 22, and the screwing tool 30 is connected in the slot 22 through magnetic attraction. In order to prevent the extension rod from easily coming out when in use, as shown in fig. 3, the connecting portion 12 is provided with an annular groove 14, the extension rod 20 is provided with a plurality of bayonets 23 corresponding to the annular groove 14, elastic members 24 are arranged in the bayonets 23, the elastic members 24 are clamped in the annular groove 14 under elastic force, so that a part of the extension rod is exposed under elastic force and clamped in the annular groove 14, and the extension rod 20 can be pulled out by overcoming the elastic force of the compression spring with the help of relatively large force. In this embodiment, the elastic component 24 is a ball 26 and a pressure spring 25 arranged on the ball 26, that is, under normal conditions, the ball 26 is clamped in the annular groove 14 by using the next part of the pressure spring 25 to expose the bayonet 23, the number of the balls 26 may be 1, or may be multiple, and in this embodiment, two balls 26 are symmetrically arranged. In addition, the screwing tool 30 is hexagonal, the slot 22 of the extension rod 20 is internal hexagonal, the screwing tool 30 is provided with a plurality of screwing tools of different types, the size is small, the weight is light, and the screwing tool can be replaced by the screwing tool of the corresponding type according to requirements.

Alternatively, the resilient member 24 may be a snap spring 27, as shown in fig. 5, and a portion of the snap spring 26 protrudes from the bayonet 23 and is clamped in the annular groove 14 to achieve the same effect.

It will be appreciated that the shapes of the connecting portion 12 and the extension rod 20 are not necessarily hexagonal prism and hexagon socket arrangements, and generally, the same effect can be achieved if the connecting portion is non-circular, and the structure of the socket 22 and the screwing tool 30 is not limited to hexagonal prism and hexagon socket arrangements.

While the invention has been shown and described with reference to the above embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
