Description

Tool head sleeve

The present invention relates to a tool head sleeve, especially a tool head sleeve with a positioning body.

In recent years, in order to satisfy the fun of self-assembly by users and consider the price of large furniture or household items, more and more products that can be assembled by themselves have appeared. When assembling, most people need to use simple tools to assist, such as various types of screwdrivers, drills, wrenches, pliers, etc. In order for the public to apply these tools more effortlessly and quickly, power tools with the aforementioned functions have also developed and grown.

Power tools are the most common type of hand-held power tools with rotating heads. In use, they can replace various tool heads according to user needs. Users can install the aforementioned screwdrivers, drills, wrenches and other tool heads on the The rotating head of the electric tool is driven by electric power for corresponding use. However, when changing the tool head, you must first stop the operation of the power tool, and then use a specific tool to remove the tool head from the rotating head, and install another tool head on the power tool instead, which causes many problems for the user. inconvenient.

Then, in order to improve the convenience of use, there is a product that first combines the tool head and the sleeve, that is, when replacing, only the sleeve and the tool head on it need to be set to the electric tool, without the need for specific assistance Tools for disassembly. However, the assembly structure of the tool head is very easy to use and fall off when it is used, which is dangerous. Because the power tool is in a state of high-speed rotation or even vibration, the sleeve-type tool head is only sleeved on the power tool. The assembly strength is insufficient and it is easy to fall off due to the influence of rotation and vibration. In the unused state, the sleeve tool head is easy for the user to drop from the power tool when holding it.

The present invention is to provide a tool head sleeve, which can not only quickly replace the tool head, but also increase the assembly strength of the tool head and the sleeve.

The tool head sleeve disclosed in an embodiment of the present invention is suitable for combining a first tool head and a second tool head. The tool head sleeve includes a set of tubes, a positioning body and at least one elastic ring. One end of the sleeve has a joint. The coupling part is used for the first tool head. The other end of the sleeve has a slot and a perforation. The slot is used for inserting the second tool head, and the hole is connected with the slot. The positioning body is located in the perforation. The elastic ring is sleeved on the sleeve. The positioning body is limited between the sleeve and the at least one elastic ring, and the positioning body is partially pressed by the at least one elastic ring and located in the slot. Wherein, when the second tool head is inserted into the slot of the sleeve, the positioning body is located in one of the positioning grooves of the second tool head.

According to the tool head sleeve of the above embodiment, through the design of the positioning body and the elastic ring, the new type realizes the advantage of quickly replacing the tool head, and enhances the assembly strength of the tool head and the sleeve, making the tool head and the sleeve difficult Produce loose.

The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principles of the present invention, and provide a further explanation of the patent application scope of the present invention.

Please refer to Figure 1 to Figure 3. FIG. 1 is a schematic perspective view of a tool head sleeve and a tool head according to the first embodiment of the present invention. FIG. 2 is an exploded schematic view of FIG. 1. 3 is a schematic cross-sectional view of FIG. 1.

The tool head sleeve 10 of this embodiment is suitable for combining a first tool head 20 and a second tool head 30. The first tool bit 20 is, for example, a drill bit that can drill different materials, such as a drill bit that drills cement, wood, or metal, and has a screw portion 22. The second tool head 30 is, for example, a cross screwdriver. However, the form of the tool head is not intended to limit the new type. In other embodiments, the first tool bit 20 may also be a slotted screwdriver or a cross screwdriver, and the second tool bit 30 may also be a slotted screwdriver.

The tool head sleeve 10 includes a set of tubes 100, a positioning body 200 and a plurality of elastic rings 300. The sleeve 100 is made of metal, for example. One end of the sleeve 100 has a coupling portion 110, and the coupling portion 110 is, for example, a screwed portion. The connecting portion 110 is used for screwing and locking the screw portion 22 of the first tool head 20. The other end of the sleeve 100 has a slot 120 and a through hole 125. The shape of the opening 121 of the slot 120 matches the shape of the second tool head 30, for example, a hexagonal shape, for the second tool head 30 to be inserted. The through hole 125 communicates with the slot 120.

In addition, the sleeve 100 has an outer wall surface 130 and an inner wall surface 140 opposite to each other. The inner wall surface 140 surrounds the slot 120. The sleeve 100 can also have a mounting slot 150. The mounting slot 150 is located on the outer wall surface 130 of the sleeve 100, and the through hole 125 connects the slot 120 and the mounting slot 150.

In addition, the sleeve 100 may also have a non-slip structure 160. The anti-slip structure 160 is located on the outer wall surface 130. The anti-slip structure 160 includes, for example, a plurality of grooves 161 arranged side by side, but it is not limited thereto. In other embodiments, the anti-slip structure 160 may also be a grid-like pattern.

The positioning body 200 is located in the perforation 125. The elastic rings 300 are located in the mounting groove 150 and sleeved on the sleeve 100. The positioning body 200 is limited between the sleeve 100 and the elastic ring 300, and the positioning body 200 is partially pressed by the elastic ring 300 and partially located in the slot 120.

In this embodiment, the elastic ring 300 is, for example, a wire ring and has a seam 310. The two seams 310 of the two elastic rings 300 are respectively located on different sides of the sleeve 100. In this way, the elasticity of one elastic ring 300 can be used to make up for the weaker elasticity of the other elastic ring 300 (such as the seam 310)

Next, please refer to FIG. 3 and FIG. 4. 4 is a schematic cross-sectional view of the second tool head of FIG. 3 engaged with the sleeve.

As shown in FIG. 3, when the second tool head 30 is inserted into the slot 120 of the sleeve 100 in the direction a, the second tool head 30 will first be blocked by the positioning body 200 and have a blocked feel.

As shown in FIG. 4, when the second tool head 30 continues to be inserted into the slot 120 of the sleeve 100 in the direction a, the second tool head 30 pushes the positioning body 200 and the elastic ring 300 outward in the direction b, so that the first The second tool head 30 can be further inserted into the slot 120 of the sleeve 100. The positioning body 200 is aligned with the positioning groove of the second tool head 30, and the positioning body 200 is pressed by the elastic ring 300 to be reset along the direction c and located in the positioning groove 32 of the second tool head 30. In this way, the second tool head 30 will be limited by the positioning body 200 and will not be detached from the sleeve 100.

On the contrary, when the user wants to pull out the second tool head 30 from the sleeve 100, the second tool head 30 is drawn out in the direction d. When the second tool head 30 continues to be withdrawn from the slot 120 of the sleeve 100 in the direction d, the second tool head 30 pushes the positioning body 200 and the elastic ring 300 outward in the direction b, so that the second tool head 30 can Withdrawn from the cannula 100.

According to the tool head sleeve of the above embodiment, through the design of the positioning body and the elastic ring, the new type realizes the advantage of quickly replacing the tool head, and enhances the assembly strength of the tool head and the sleeve, making the tool head and the sleeve difficult Produce loose.

Although the present invention is disclosed as above with the foregoing embodiments, it is not intended to limit the new model. Anyone who is familiar with similar arts can make some changes and retouching without departing from the spirit and scope of the new model. The scope of patent protection for new models shall be subject to those defined in the scope of patent applications attached to this specification.
