Description

Rotary positioning device for tool transmission shaft

This creation is about a hand-held tool, especially a rotary positioning device for a tool drive shaft that can replace various screwdrivers.

Press, the existing hand-held tools, whether electric or manual, have the function of replacing tool parts in order to facilitate use according to various situations, especially for locking or removing screws such as straight, cross, or hexagonal screws When moving, the corresponding screwdriver is often used.

However, traditional hand-held tools are usually not designed to facilitate users to disassemble and replace components. For example, US Pat. No. 9,566,696 discloses a handheld mechanical tool, which is not convenient for rapid tool replacement. And it is not strong enough to replace the tool. Therefore, under the existing design that is not easy to replace, the traditional hand-held tools often have many inconveniences in use, and it is easy to cause troubles in construction and other operations.

In view of this, in order to improve and solve the above-mentioned deficiencies, the author is dedicated to research and cooperate with the application of the theory, and finally proposes a reasonable design and effectively improves the above-mentioned deficiencies.

The main purpose of this creation is to provide a tool drive shaft rotation positioning device, which is for users to quickly disassemble, and facilitate the replacement and assembly of tools such as screwdrivers, so as to suit their operation needs.

In order to achieve the above purpose, the present invention provides a tool drive shaft rotation positioning device, including an adapter and a clutch assembly, the adapter has a seat, and an engaging portion extending forward from the seat, and to An assembly hole is axially penetrated by the engaging portion and penetrates into the seat. The clutch assembly includes a set of rotating sleeve provided outside the seat, an elastic element connected between the rotating sleeve and the seat, and through the seat A fixing part that can partially protrude into the assembly hole; wherein, the inner wall of the rotating sleeve is concavely provided with a withdrawal groove, and when the rotating sleeve pulls the elastic element and twists on the seat, the withdrawal groove can be correspondingly fixed To make the fixing part withdraw from the assembly hole.

In order to further reveal the characteristics and technical content of this creation, please refer to the following detailed description and drawings related to this creation, however, the drawings are only for reference and description, and are not intended to limit this creation.

Please refer to FIG. 1 and FIG. 2, which are a three-dimensional exploded view and a three-dimensional assembly schematic diagram of this creation, respectively. This creative department provides a tool drive shaft rotation positioning device, including an adapter 1, and a clutch assembly 2; wherein:

The adapter 1 can be set on a hand-held tool (figure omitted), which is convenient for human hands to hold and operate. The adapter 1 has a base portion 10 and an engaging portion 11 extending forward from the base portion 10, and an assembly hole 12 penetrates axially from the front end of the engaging portion 11 to penetrate into the base portion 10 to The screw shaft 3 of various specifications (that is, as shown in FIG. 5) extends into the assembly hole 12 for use. In addition, the outer periphery of the connecting portion 11 may be a polygon such as a four-corner or six-corner, which is used in conjunction with other tools to install through a sleeve with a latch nut corresponding to its number of angles; in this creation, the If the outer periphery of the engaging portion 11 has a quadrangular shape, it can be installed on the engaging portion 11 with a tool having a quadrangular nut, thereby facilitating the operation and use of the tool.

The clutch assembly 2 includes a set of rotating sleeve 20 disposed outside the seat 10, an elastic element 21 connected between the rotating sleeve 20 and the seat 10, and partially protruding through the seat 10 To the fixing member 22 in the assembling hole 12, the fixing member 22 may be closely arranged by one or a plurality of spheres 220 and filled in the fixing hole 100 on the seat body 10. Please refer to FIG. 3 and FIG. 4 together. In the embodiment of the present creation, a receiving groove 200 is recessed in the rotating sleeve 20 for the elastic element 21 to be disposed therein. The elastic element 21 can be a torsion spring, and has a spring portion 210, and a first end 211 and a second end 212 respectively extending from the two ends of the spring portion 210, wherein the first end 211 is bent inwardly It is connected to the seat 10 (as shown in FIG. 5 ), and a rotating groove 201 for receiving the first end 211 is provided in the rotating sleeve 20, and the second end 212 is bent outward and connected to the The rotating sleeve 20 can be provided with a positioning groove 202 for fixing the second end 212 on the rotating sleeve 20; thereby, the rotating sleeve 20 can be subjected to force (such as manual force) on the seat 10 When the upper part is twisted, the elastic element 21 can be pulled for elastic deformation, and after the rotation sleeve 20 is released from the force, the elastic force of the elastic element 21 is used to reversely reverse to automatically restore the initial state.

As mentioned above, this creation is mainly based on the fact that a retreat groove 203 is recessed on the inner wall of the rotating sleeve 20, and when the rotating sleeve 20 is twisted on the seat 10 according to the traction elastic element 21, the retreating The unloading groove 203 can be twisted by the rotating sleeve 20 and brought to a position corresponding to the fixing member 22, so that the fixing member 22 can be retracted to the unloading groove 203 without partially protruding into the assembly hole 12.

In addition, please refer to FIG. 1 and FIG. 2 again, a set of limit ring 213 fixed on the seat 10 can be further added to the rear end of the rotary sleeve 20, and a limiter is provided in the rotary sleeve 20 for the limit The limiting groove 204 in which the ring 213 is inserted prevents the elastic element 21 from being exposed. Moreover, in order to facilitate the rotation sleeve 20 to be limited to the seat 10, a C-ring 205 can be further resisted at the front end of the rotation sleeve 20, and the C-ring tether is buckled on the seat 10上的扣槽101。 The buckle groove 101. The seat 10 may also be provided with an insertion hole 102 for the first end 210 of the elastic element 21 to be fixed.

Therefore, with the above-mentioned structure, the rotation positioning device of the transmission shaft of the authoring tool can be obtained.

According to this, as shown in FIG. 5 and FIG. 6, when the screwdriver shaft 3 is to be assembled, only the torsion rotation sleeve 20 is needed to retract the fixing member 22 into the withdrawal groove 203, and the screwdriver shaft can be supplied at this time 3 Insert one end into the assembly hole 12 and at the same time extend the insertion groove 30 on the screwdriver shaft 3 to the position corresponding to the fixing member 22; then, as shown in FIGS. 7 and 8, release the rotation sleeve 20 After twisting the external force, the rotating sleeve 20 can be reversely twisted by the elastic torsion force of the elastic element 21, so that the rotating sleeve 20 pushes the fixing member 22 into the assembly hole 12 to bear against the insertion groove of the driver shaft 3 30, so that the assembly of the screwdriver shaft 3 can be completed and not easy to fall off.

In summary, this creation is really a rare new creation product, which can indeed achieve the intended use, and solve the lack of knowledge, and because it is extremely novel and progressive, it fully meets the requirements of the new patent application. To file an application in accordance with the Patent Law, please check and grant the patent in this case in detail to protect the rights of the creator.

However, the above is only the preferred and feasible embodiment of this creation, and the patent scope of this creation is not restricted, so any equivalent structural changes caused by the use of this creation description and the content of the drawings are included in this book for the same reason.
