Referring to FIGS. 1 through 5, the present invention is a multifunctional tool structure including a handle 10, a base 20, a cover portion 30, and a sleeve portion 40.

The handle 10 is formed by plastic injection molding; the top of the handle 10 has an annular opening 11 and two engaging recesses 12, and the two engaging recesses The 12 series is symmetrically recessed on the inner surface of the annular opening 11.

The base 20 has a cylindrical shape and has a plurality of blocking portions 21, a plurality of receiving grooves 22 and a bottom portion 23; the blocking portion 21 and the receiving groove 22 are alternately arranged around the periphery of the base 20 The front end of each of the dams 21 has a first joint portion 211, and one of the outer portions of the dam portion 21 has an elastic component 212; the accommodating groove 22 is for accommodating a tool head 70, and The bottom portion 23 has at least two engaging convex portions 231 and a tool fixing concave portion 232 for engaging with the engaging concave portion 12 of the handle 10, and the tool fixing concave portion 232 is used for Fix the tool head 70 (see Figure 3). In the present embodiment, the tool head 70 has a working end 71 and a fixed end 72 for fixing to the tool fixing recess 232 of the base 20, and the cross-sectional shape of the fixing end 72. The hexagonal shape of the tool fixing recess 232 is a corresponding hexagonal recess. Of course, the type of the tool head 70 in each of the accommodating grooves 22 can be arbitrarily matched according to the needs of the user.

In the design, the engaging recess 12 has a guiding slot 121 and an engaging slot 122. The guiding slot 121 and the engaging slot 122 are recessed on the inner surface of the annular opening 11. The 121 is recessed from the top surface of the annular opening 11 , and the engaging groove 122 is located below the guiding groove 121 , and one end is connected to the guiding groove 121 ; the handle 10 and the base 20 are In the assembly, the engaging convex portion 231 is firstly engaged with one end of the engaging groove 122 via the guiding groove 121, and then the base 20 is rotated clockwise (this embodiment is a clockwise design, in practice) In the above, the engaging convex portion 231 can be abutted against the other end of the engaging groove 122, that is, the assembly of the handle 10 and the base 20 is completed. Regarding the engaging recess 12 and the engaging convex portion 231 Quantity, the present invention is described by two relative design, and the number can be changed according to different needs during production.

The cover portion 30 is provided with a plurality of second joint portions 31 for correspondingly connecting and connecting the first joint portions 211 of the base 20 to the bottom ring. In this embodiment, the first joint portion 211 is a recessed hole, and the second joint portion 31 is a corresponding one of the bumps. The cover portion 30 is combined by a combination of the recessed holes and the bumps. On the base 20. Of course, the arrangement of the recessed holes and the bumps may be interchanged, so that the first joint portion 211 is a bump, and the second joint portion 31 is a recessed hole; in addition, the first joint portion 211 and the The second joint portion 31 is a close fit.

The sleeve portion 40 has a hollow cylindrical shape and has a side opening 41 and a plurality of recesses 42. The side opening 41 is recessed on one side of the sleeve portion 40, and the plurality of recesses 42 are looped on the sleeve portion 40. An inner surface of the sleeve portion 40; the sleeve portion 40 is sleeved on the base 20 and interposed between the handle 10 and the cover portion 30, and the elastic component 212 is pedestal to the groove 42. When the sleeve portion 40 is rotated by an external force, the elastic component 212 is forced to be temporarily deformed to switch the corresponding groove 42.

Therefore, in use, after the handle 10 is separated from the base 20, the tool head 70 can be obtained by the rotation of the sleeve portion 40 to the side opening 41 corresponding to one of the tool heads 70. The side opening 41 is taken out and fixed to the tool fixing recess 232 of the base 20 for use.

As shown in FIG. 2 , the elastic component 212 has a recessed hole 212A, an elastic component 212B and a steel ball 212C. The lateral recess 212A is disposed on the outer side of the stopper 21 . The elastic member 212B can be a spring. The two ends are respectively abutted against the end wall of the side recessed hole 212A and the steel ball 212C, and the steel ball 212C is pressed against the groove 42 of the sleeve portion 40 by the elastic force of the elastic member 212B (as shown in FIG. 5). Therefore, the steel ball 212C can be properly engaged with the groove 42 by the elastic force of the elastic member 212B, and the steel ball 212C and the concave portion are rotated when the sleeve portion 40 is rotated by an external force. The groove 42 is separated, and the inner surface of the sleeve portion 40 forces the steel ball 212C to compress the elastic member 212B to switch the corresponding groove 42 (this is a common segmentation positioning technique, which will not be described in detail herein).

In more detail, the present invention can be easily achieved by the rotation of the sleeve portion 40 in the storage and tool use; for example, when the side opening 41 of the sleeve portion 40 corresponds to the blocking portion 21 In this case, the sleeve portion 40 can limit each of the tool heads 70 to each of the accommodating grooves 21, which is a storage state (that is, the state of FIG. 1); as shown in FIG. 6, when the user needs to use When the tool head 70 is rotated, the sleeve portion 40 is rotated, and the side opening 41 is corresponding to the receiving groove 22 of the tool head 70, and the tool head 70 can be taken out through the side opening 41 (eg, 7 and 8) Finally, the fixed end 72 of the tool head 70 is assembled to the tool positioning recess 232 of the base 20 (i.e., the state of the third and fourth figures).

As shown in FIG. 9, the handle 10 is further provided with an internally threaded hole 13 and a cutter portion 14 which is disposed below the annular opening 11 and communicates with the annular opening. The cutter portion 14 is fixed in the handle 10 and extends outward from the bottom of the handle 10. Structurally, the cutter portion 14 can be made of metal. The cutters, the scrapers, the can openers, and other common functions of daily life are combined on a cutter; and in terms of production, the present invention is plastically formed on the cutter portion 14 to form the grip 10, thereby causing the cutter portion 14 The handle 10 is fixed to each other.

As shown in FIG. 10, the internally threaded hole 13 can be used in combination with a thread 81 (or other threaded end) of a commercially available broom 80 to increase the overall length of the handle 10. The range and height of use of the cutter portion 14 are increased.

In addition, the cover portion 30 is made of a metal material (for example, galvanized copper), and has the advantage of being knockable in function, and the hardness of the metal can be used to reduce the damage of the tapping process; It is shown that when a lock member 91 is locked on the surface of a predetermined object 90 and the end is not flat, the present invention can be tapped by aligning the cover portion 30 with the lock member 91, thereby causing the end of the lock member 91 to be reached. smooth.

As can be seen from the above description, the present invention can quickly take out the required tool head 70 by the rotation of the sleeve portion 40, and the volume is quite compact after being stored, and is equivalent in carrying and use. Convenience.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects, and the invention has been in accordance with the provisions of the patent law.
