Description

Technical Field

[0001] The utility model belongs to the technical field of sleeves, and in particular relates to a sleeve connecting piece. Background Art

[0002] The electric drill is a drilling tool that uses electricity as power. It is a common product among power tools and is also the most in-demand power tool product. The annual production and sales volume accounts for 35% of China's power tools. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and work operation, and drives the operating device through the transmission mechanism, driving the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and better penetrates the object. The electric drill also has another function, which is to install and remove bolts by installing the drill sleeve.

[0003] However, when the existing drill sleeve is used, when installing or removing different types of bolts, the drill sleeve needs to be replaced directly on the electric drill body, which is inconvenient to operate and reduces the efficiency of on-site construction, and has certain defects. Utility Model Content

[0004] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a sleeve connector.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sleeve connector, comprising a hollow sleeve body, a first connecting section for connecting to a drill bit is provided at one end of the sleeve body, an installation cavity is provided at the opening of the first connecting section, an annular magnet is provided in the installation cavity, and a positioning clamp for preventing the drill bit from loosening is also provided on the first connecting section.

[0006] By adopting the above technical solution and using an annular magnet, the drill bit can be quickly replaced without replacing the drill sleeve. It has wide applicability, is easy to use, easy to assemble, and has high stability. It can be used for three-in-one connection of furniture, and can also be used for disassembly of ordinary screws, which saves time and effort and is efficient in installation. The annular magnet is arranged at the top of the sleeve. First, it is more convenient to process, and second, the top is subjected to force, and the stability of the connection is further enhanced.

[0007] The utility model is further configured as follows: the side wall of the first connecting section is provided with an annular mounting groove and a mounting hole vertically arranged on the annular mounting groove, the mounting hole is opened at both ends, the positioning clamp includes an elastic clamping bead arranged in the mounting hole and a limiting clamping ring for preventing the elastic clamping bead from detaching, and the limiting clamping ring is provided with a clamping hole smaller than the diameter of the elastic clamping bead at the position corresponding to the mounting hole.

[0008] By adopting the above technical solution, the elastic bead can be quickly inserted into the drill bit slot by simply pushing the sleeve body. Compared with tightening the bolts, it is easy to use and simple to disassemble and assemble. A limit ring is provided to further enhance stability.

[0009] The utility model is further provided that: the limiting clamp ring is provided at the other side opening relative to the limiting clamp hole.

[0010] By adopting the above technical solution, the limiting clamp ring has a certain degree of adjustability, and the depth of the elastic clamping bead can be adjusted.

[0011] The utility model further provides that: the sleeve body includes a second connecting section arranged at the other end, the outer diameter of the first connecting section is larger than the outer diameter of the second connecting section, the inner diameter of the first connecting section is consistent with the inner diameter of the second connecting section, and the inner diameter of the annular magnet is consistent with the inner diameter of the second connecting section.

[0012] By adopting the above technical solution, the inner diameter is consistent and can be quickly installed with an electric drill. The inner diameter is unlimited and the position and depth can be adjusted according to the needs of different drill bits. At the same time, the two ends can be inserted interchangeably. It can be used for three-in-one connection of furniture and can also be used for removing ordinary screws.

[0013] The specific implementation of the utility model is described below in conjunction with the drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
