[0035] Example

[0036] This embodiment provides a multifunctional portable tool, such as Figure 1-Figure 4 As shown, the specific structure is as follows.

[0037] Combination Figure 1As shown, the multifunctional portable tool of this embodiment is mainly composed of five parts: a handle 1, a tool head 2, a telescopic mechanism 3, a locking mechanism 4 and a rotation adjustment mechanism 5. The handle 1 is convenient for holding by hand; the tool head 2 is used for striking, cutting or twisting, and measuring; the telescopic mechanism 3 allows the overall length of the multifunctional portable tool to be changed; the locking mechanism 4 is used to fix the tool head 2 to prevent it from rotating loose; and the rotation adjustment mechanism 5 is used to adjust the angle of the tool head 2 to adapt to different occasions.

[0038] Furthermore, the handle 1 is in the shape of a vertical strip and can be made of wood or a metal tube. A rubber anti-skid layer is pasted on the surface of the handle 1 to increase the friction of holding and reduce the slipping during use. Three holding grooves 103 are arranged on the surface of the handle 1 from top to bottom. The holding grooves 103 are used to accommodate fingers when holding, making the holding more comfortable.

[0039] In some implementations of this embodiment, Figure 2 As shown, the telescopic mechanism 3 includes two parts: a sleeve 301 and a telescopic limit column 303, wherein the sleeve 301 is a sleeve made of metal material, and a guide rod 102 is fixed on the top of the handle 1. The diameter of the guide rod 102 is less than or equal to the inner diameter of the sleeve 301, and the guide rod 102 can be inserted from the bottom of the sleeve 301 and move up and down.

[0040] Further, combined with Figure 1 and Figure 2 As shown, the side wall of the sleeve 301 is provided with two through holes 302, and the two through holes 302 are arranged vertically. The side wall of the guide rod 102 is provided with a horizontal groove 1021, the left end of the telescopic limit column 303 is a plane, and the right end of the telescopic limit column 303 is a hemispherical surface, and the left end of the telescopic limit column 303 is inserted into the groove 1021. A spring 304 is installed in the groove 1021, the left end of the spring 304 abuts against the bottom of the groove 1021, and the right end of the groove 1021 abuts against the left end of the telescopic limit column 303. The spring 304 is compressed and has a tendency to push the telescopic limit column 303 to the right.

[0041] It should be noted that if Figure 2 As shown, two baffles 3031 are installed on the left side of the side wall of the telescopic limit column 303, one above and one below, and a limit groove 1022 is respectively provided on the upper and lower side walls of the groove 1021, and the baffle 3031 slides in the limit groove 1022. At the same time, the limit groove 1022 restricts the baffle 3031 to prevent the telescopic limit column 303 from being pushed out of the groove 1021. When the position length needs to be adjusted, the protruding telescopic limit column 303 is pressed, and the telescopic limit column 303 withdraws from the through hole 302, which facilitates the upward and downward movement of the guide rod 102, and then the telescopic limit column 303 is inserted into the corresponding through hole 302 to achieve fixation.

[0042] In some implementations of this embodiment, a connecting sleeve 3011 is fixedly installed at the top of the sleeve 301, and a thread groove 101 is provided inside the connecting sleeve 3011. The thread groove 101 and the thread head 201 are fixed in a threaded connection. A notch is provided on the right side of the top of the connecting sleeve 3011 as a second card slot 3012.

[0043] Furthermore, a locking mechanism 4 is installed at the top of the side wall of the sleeve 301, including a pressing piece 401 and an L-shaped limit card strip 402. The pressing piece 401 is curved, and the L-shaped limit card strip 402 is L-shaped. The pressing piece 401 and the L-shaped limit card strip 402 are fixed to each other. A hinge seat is installed at the top of the side wall of the sleeve 301. The rotating rod of the hinge seat passes through the lower end of the L-shaped limit card strip 402. The pressing piece 401 and the L-shaped limit card strip 402 can rotate around the rotating rod of the hinge seat. At the same time, a torsion spring is installed on the rotating rod of the hinge seat. The torsion spring is connected to the L-shaped limit card strip 402 to ensure that the pressing piece 401 and the L-shaped limit card strip 402 have a tendency to rotate counterclockwise. The L-shaped limit card strip 402 can be inserted into the second card slot 3012 and extend into the interior of the connecting sleeve 3011.

[0044] Furthermore, combined Figure 2 and Figure 3 As shown, the thread head 201 is provided with a vertical slot 2011 for the L-shaped limit clamping strip 402 to extend into. When the thread head 201 and the connecting sleeve 3011 are threadedly connected, the end of the L-shaped limit clamping strip 402 is automatically inserted into the slot 2011, and the L-shaped limit clamping strip 402 cannot rotate, so that the thread head 201 cannot rotate either, and the locking effect is good. When the thread head 201 needs to be rotated, the thumb presses the pressing piece 401 to make the end of the L-shaped limit clamping strip 402 tilt up and automatically withdraw from the slot 2011 without affecting the rotation of the thread head 201.

[0045] In some implementations of this embodiment, Figure 1 and Figure 4 As shown, the rotation adjustment mechanism 5 includes five parts: a stud 501, a screw sleeve 502, a retaining ring 503, a connecting rod 504 and a clamping plate 505. The stud 501 is fixedly connected to the top of the threaded head 201, the outer wall of the stud 501 is provided with an external thread, and the screw sleeve 502 has an internal thread and is threadedly connected to the stud 501.

[0046] Further, combined with Figure 4As shown, the retaining ring 503 is fixed to the inside of the screw sleeve 502, and the top of the retaining ring 503 is level with the top of the screw sleeve 502. The connecting rod 504 is fixed to the bottom of the tool head 2, and the diameter of the connecting rod 504 is slightly smaller than the inner diameter of the retaining ring 503, so that the connecting rod 504 can be inserted into the inside of the retaining ring 503. The disc-shaped clamping plate 505 is fixed to the bottom end of the connecting rod 504, and the diameter of the clamping plate 505 is larger than the inner diameter of the retaining ring 503. When the screw sleeve 502 is rotated, the screw sleeve 502 can rise or fall. After the screw sleeve 502 rises, the bottom of the retaining ring 503 and the top of the stud 501 increase in spacing, and the clamping plate 505 can be rotated, thereby facilitating the rotation of the tool head 2 and adjusting the direction of the tool head 2. After the screw sleeve 502 descends, the bottom of the retaining ring 503 and the top of the stud 501 decrease in spacing, and the clamping plate 505 is clamped by the bottom of the retaining ring 503 and the top of the stud 501 to prevent the tool head 2 from rotating.

[0047] It should be noted that in order to improve the stability of the fixation, a layer of rubber sheet 506 is installed at the bottom of the card plate 505, and the top of the stud 501 can be provided with rough texture. The contact friction between the rubber sheet 506 and the top of the stud 501 is greater, thereby improving the fixing effect.

[0048] It should be noted that the tool head 2 may be a hammer (such as Figure 1 As shown), saws, chisels, awls or rulers can achieve different effects and are suitable for more occasions.

[0049] The working principle of the multifunctional portable tool of the utility model is as follows:

[0050] The tool head 2 is connected to the handle 1 by a threaded connection, which is convenient for replacing different tool heads 2 and realizing multiple functions. The telescopic mechanism 3 allows the handle 1 to change its length to adapt to different occasions. The locking mechanism 4 is used to fix the tool head 2 to prevent rotation and looseness, and enhance the stability of the connection. The rotation adjustment mechanism 5 is used to adjust the angle of the tool head 2 to adapt to different occasions. The threaded connection and the locking mechanism 4 can prevent the tool head 2 from loosening. The multifunctional portable tool can complete all functions, such as knocking, cutting, and twisting. It is suitable for various forms of tool heads 2 and has good versatility. Therefore, only one handle 1 and several tool heads 2 are needed in a tool box, which increases the utilization rate of the tool box. More tool heads 2 can be carried in the same space, and the portability is good.
