Abstract
The utility model discloses a kind of cylinder sleeve on electric tool, comprise liner body, also comprise the mandrel one and mandrel two that coaxially arrange with liner body, described mandrel one and mandrel two are respectively equipped with boss one and boss two, described mandrel one and the die casting of mandrel two difference are at liner body two ends, thus making boss one and boss two die casting in liner body, described mandrel one is provided with threaded portion away from liner body one end, and described mandrel one is one-body molded with threaded portion.A kind of cylinder sleeve on electric tool that the utility model obtains, its technique effect is: adopt the threaded portion on mandrel one and mandrel one, be spirally connected drill bit, chuck is replaced to fix drill bit, its good fixing effect, stability in use improves, and mandrel one and liner body die cast, Stability Analysis of Structures, though in the long-term High Rotation Speed of drill bit and impact process also not easy fracture between mandrel and liner body.
Description
Technical field
The utility model relates to a kind of cylinder sleeve on electric tool.
Background technology
The cylinder sleeve used in electric tool, comprise liner body and be arranged on the chuck of connection drill bit of liner body one end, but in use, the connection of chuck and cylinder sleeve is not very firm, in the long-term High Rotation Speed of drill bit and impact process, probably cause the fracture between chuck and liner body, affect the normal use of whole electric drill.
Summary of the invention
The purpose of this utility model providing a kind of sound construction to solve above-mentioned the deficiencies in the prior art, using the cylinder sleeve on electric tool that is stable and not easy fracture.
To achieve these goals, a kind of cylinder sleeve on electric tool designed by the utility model, the mandrel one and the mandrel two that comprise liner body and coaxially arrange with liner body, described mandrel one and mandrel two are respectively equipped with boss one and boss two, described mandrel one and the die casting of mandrel two difference are at liner body two ends, thus making boss one and boss two die casting in liner body, described mandrel one is provided with threaded portion away from liner body one end, and described mandrel one is one-body molded with threaded portion.
Further, described liner body, mandrel one and mandrel two is circular, and the radius of described liner body is greater than the radius of mandrel one, and the radius of described mandrel one is greater than the radius of mandrel two, described threaded portion is also circular, and the radius of threaded portion is equal with the radius of mandrel two.
Further, described liner body is aluminium material, and described mandrel one is steel matter with mandrel two.
A kind of cylinder sleeve on electric tool that the utility model obtains, its technique effect is: adopt threaded portion on mandrel one and mandrel one to the drill bit that is spirally connected, chuck is replaced to fix drill bit, its good fixing effect, stability in use improves, and mandrel one and liner body die cast, Stability Analysis of Structures, though in the long-term High Rotation Speed of drill bit and impact process also not easy fracture between mandrel and liner body.
Accompanying drawing explanation
Fig. 1 is a kind of cylinder sleeve structural representation on electric tool of the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of cylinder sleeve on electric tool that the utility model provides, comprise liner body 1 and with the coaxial mandrel 1 arranged of liner body 1 and mandrel 23, described mandrel 1 and mandrel 23 are respectively equipped with boss 1 and boss 25, described mandrel 1 and the die casting of mandrel 23 difference are at liner body 1 two ends, thus make boss 1 and boss 25 die casting in liner body 1, described mandrel 1 is provided with threaded portion 6 away from liner body 1 one end, and described mandrel 1 is one-body molded with threaded portion 6.
In the present embodiment, described liner body 1, mandrel 1 and mandrel 23 is circular, and the radius of described liner body 1 is greater than the radius of mandrel 1, and the radius of described mandrel 1 is greater than the radius of mandrel 23, described threaded portion 6 is also circular, and the radius of threaded portion 6 is equal with the radius of mandrel 23.
In the present embodiment, described liner body 1 is aluminium material, and described mandrel 1 is steel matter with mandrel 23.
A kind of cylinder sleeve on electric tool that the utility model obtains, its technique effect is: adopt threaded portion 6 on mandrel 1 and mandrel 1 to the drill bit that is spirally connected, chuck is replaced to fix drill bit, its good fixing effect, stability in use improves, and mandrel 1 and liner body 1 die cast, Stability Analysis of Structures, though in the long-term High Rotation Speed of drill bit and impact process also not easy fracture between mandrel and liner body.
