Description

Quick adapter for drilling and locking screws for electric drills

This creation is about a quick adapter for drilling and locking screws for electric drills, especially a dual-purpose electric drill adapter that can replace drilling tools and screw locking tools at any time for its creators.

According to, generally speaking, in order to improve work efficiency and save energy, professional masters will assist with tools such as electric drills for drilling or screwing operations. When making a machined part, the master usually performs the two steps of drilling and locking the screw in succession, that is to say, it is usually necessary to drill a hole on the machined part before locking the screw. For the sake of labor saving, some construction workers use electric power tools with drill bits to drill holes, remove the drill bits and replace them with screw locks to lock the screws in the holes, and then replace them with drills. Drill bits for holes; even, in order to increase work efficiency, some construction workers often carry two electric power tools when working. First use the power tool with the drill bit to drill the hole, and then replace the power tool with the screw lock The machine locks the screw in the hole.

The above-mentioned construction methods have caused additional burdens on the constructor in terms of efficiency, cost and physical strength; therefore, it is like Taiwan Patent Publication No. M509087. Drilling with elastic collets for electric hammers and electric drills has both fast and fast locking screws. Connecting rod, the quick connecting rod is a hollow rod body, both ends of which are respectively provided with a first socket part and a first screw part, the first socket part is connected with a polygonal screw lock, and the second The socket part includes a first sphere and an outer ring sleeve, and the outer wall of the first socket part is provided with a first annular groove. The first annular groove is provided with a first through hole. The perforation system accommodates the first sphere, and the first socket part is provided with a polygonal hole. The outer ring sleeve presses the first sphere so that the first sphere is located in the first perforation and protrudes from the first sphere. The inner wall surface of the first socket; and the first screw part has a continuous thread outside, and the first screw part is provided with a tapered hole, the tapered hole has an inner taper; the first screw The part is combined with a nut, the nut is a hollow sleeve, which is sleeved outside an elastic collet, the elastic collet is a hollow cylinder with an outer taper, which corresponds to the tapered hole And the elastic collet is cut into multiple equal parts, and one end of the elastic collet has a flange, and the two ends of the nut are respectively provided with a second socket part and a second screw part, The second socket part is connected to a drill bit, the second screw part is provided with a continuous thread and is correspondingly combined with the first screw part, and between the second socket part and a second screw part The system has a concave groove, so that the flange is caught in the concave groove.

The above structure must be achieved by assembling the spheres. However, the manufacturer needs to assemble the spheres during the assembly process, and the general assembly personnel know that the rolling spheres are not easy to assemble, resulting in time-consuming and increased personnel costs.

The reason is that, based on years of rich experience in design, development and actual production in the related industry, the creators provide a quick adapter for drilling and locking screws for electric drills in order to achieve better practical value.

The main purpose of this creation is to provide a quick adapter for drilling and locking screws for electric drills, especially a dual-purpose electric drill adapter that can replace drilling tools and screw locking tools at any time.

The main purpose and function of the quick adapter for drilling and locking screws for electric drills are achieved by the following specific technical means:

It mainly includes a shell and an elastic part assembled in the shell, an assembly part and a fixing ring, wherein one end of the assembly part can be installed corresponding to a drilling tool, and a breach chute is provided on the wall surface. The elastic member is correspondingly embedded in the breach chute; thereby, the other end of the assembly member of the quick adapter is embedded corresponding to the screw locking tool of the electric drill, and the elastic member located in the breach chute is clamped on the screw. The groove of the tool is locked to locate the quick adapter, which achieves the effect of convenient and fast assembly.

In the preferred embodiment of the quick adapter for drilling and locking screws for an electric drill, the assembly is provided with a stop ring protruding on the outer surface, and the stop ring divides the assembly into the first One end portion and a second end portion, the first end portion is provided with a first inner hole for the screw locking tool to be inserted, and a breach chute is provided on the surface, and the breach chute communicates with the The first inner hole, and then the first end portion is correspondingly embedded in the housing space of the housing, and the second end portion is provided with a second inner hole, and the second inner hole can correspond to the mounting group Set up a drilling tool.

The preferred embodiment of the quick adapter for drilling and locking screws for electric drills of the invention, wherein the elastic member is correspondingly sleeved on the first end of the assembling member, and is limited to the limit ring Between the abutting edge, the elastic piece is provided with a detent section, and the detent section is correspondingly embedded in the breach chute.

In order to have a more complete and clear disclosure of the technical content, the purpose of the creation and the effects achieved in this creation, we will explain them in detail below, and please refer to the figures and figure numbers disclosed together:

First of all, please refer to the three-dimensional exploded and cross-sectional schematic diagram of the quick adapter for drilling and locking screws for electric drills created in the first and second drawings. A screw lock tool is set on the rotating end of the electric drill (1). (2) A ring groove (21) is provided on the screw locking tool (2), and a quick adaptor (3) can be assembled correspondingly, and the quick adaptor (3) includes:

A housing (31) with an accommodating space (311) inside, one end of the accommodating space (311) is an open end (312), and the other end forms an abutting edge (313);

A set of components (32), a limit ring (321) protruding on the outer surface, the limit ring (321) divides the assembly (32) into a first end (322) and a second end The end (323), the first end (322) is provided with a first inner hole (324) for the screw locking tool (2) to be inserted, and a breach chute (325) is provided on the surface, The breach chute (325) communicates with the first inner hole (324), and the first end (322) is correspondingly embedded in the housing space (311) of the housing (31), and The second end (323) is provided with a second inner hole (326), and the second inner hole (326) can be correspondingly installed with a drilling tool (4);

An elastic member (33) is correspondingly sleeved on the first end (322) of the assembly member (32), and is limited by the limiting ring (321) and the abutting edge (313) In between, the elastic member (33) is provided with a detent section (331), and the detent section (331) is correspondingly embedded in the breach chute (325);

A fixing ring (34) is correspondingly embedded in the open end (312) of the housing (31) to restrict the positioning of the first end (322) of the assembly (32).
