Description

Electric drill adapter sleeve structure

This creation is about an electric drill application field, especially an electric drill adapter sleeve structure.

The use of power tools is quite common in construction or hydropower projects. When the construction personnel drill and lock the work on the working plane such as the cement wall, such as installing signboards, erecting air-conditioning or formwork engineering, the construction personnel must carry the electric drill and the replaceable drill bit and screwdriver head with them. After the tool is used, in the first stage of the construction work, the drill bit is first mounted on a sleeve and disposed on the electric drill through the sleeve to drive the drill bit to drill on the working plane by the electric drill. Next, the drill bit is taken out of the sleeve and the bit is mounted on the sleeve to perform the second stage of construction work. Then, a locking component such as a screw or a bolt is placed in the borehole, and the driver's head is abutted against the locking component to drive the driver's head by the electric drill to perform the locking operation of the locking component on the working plane. Construction work.

However, before each drilling and locking operation, the construction personnel need to carry tools such as drill bits and screwdrivers respectively, so that the construction workers may have problems in carrying and storing in the case of an increase in the number of tools. Moreover, during drilling and locking operations, the constructor often operates repeatedly between the drilling and the rotating locking component. When the constructor takes the drill bit out of the sleeve, the drill bit to be removed is first placed on the tool. In the box or pocket, then look for the screwdriver in the tool box or pocket and install it on the sleeve. In this process, in addition to taking a considerable amount of time, it is easy to cause the bit and/or the bit to be dropped/lost during the replacement process; therefore, the operation is very inconvenient.

In view of this, the creator has improved the shortcomings of the prior art, and after years of experience in this industry, he created the creation.

Therefore, the purpose of this creation is to solve the above problems and provide an electric drill The sleeve structure is such that the ball and the compression spring can pass through the opening in the annular elastic piece of the concave ring section of the cylinder, and the ball and the compression spring are placed in the radial tapered hole of the concave ring section; Then, the annular elastic piece is slightly rotated by an angle with respect to the concave ring segment, so that the body of the annular elastic piece is pressed against the end of the compression spring away from the ball; thereby, the structure is not only simple, but also easy to operate, and can be easily assembled and disassembled.

In order to achieve the above object, the present invention provides an electric drill adapter sleeve structure, comprising a cylinder having a tubular portion, a closed end and an open end, the closed end and the open end being respectively disposed at the tubular portion At both ends, the open end is detachably fixedly disposed by a drilling member, and the tubular portion is provided with a concave ring segment adjacent to the open end, and the concave ring segment is radially provided with a tapered hole, the cone The diameter of the shaped hole is gradually enlarged from the inside of the concave ring segment toward the outside; a connecting member extends outward from the closed end axis of the cylinder, and the connecting member is disposed coaxially with the cylinder; a ball is mounted in the tapered hole, and partially exposes the inside of the concave ring segment; a compression spring is disposed in the tapered hole, and one end of the compression spring is abutted against the ball And an annular elastic piece sleeved on the concave ring segment, and the annular elastic piece has a body and an opening, the opening is disposed at a predetermined portion of the body, the opening is for the ball and the compression spring to pass through And the ball and the compression spring are placed in the tapered hole, and then A rotation angle slightly annular elastic piece, so that the annular body of the resilient piece for an end remote from the compression spring abuts against the balls.

In some embodiments, the open end of the cylinder is axially formed with a hexagonal hole for the drilling member having a hexagonal projection and is fixed by the ball and the compression of the compression spring. .

In some embodiments, the connector has a hexagonal cross-section for detachable attachment to an electric drill.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings.

Of course, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings.

The electric drill adapter sleeve structure 100 of the present embodiment includes a cylinder 1, a connecting member 2, a ball 3, a compression spring 4, and an annular elastic piece 5.

The cylinder 1 can have a tubular portion 11, a closed end 12 and an open end 13. The closed end 12 and the open end 13 are respectively disposed at two ends of the tubular portion 11, and the open end 13 is provided with a drilling member 6 The recessed portion is fixedly disposed, and the tubular portion 11 is provided with a concave ring segment 14 adjacent to the open end 13 .
