Description

Technical Field

[0001] The utility model relates to a power tool, in particular to an angle-adjustable power tool. Background Art

[0002] There are many types of hand tools, for example but not limited to wrenches, pliers, hammers, pneumatic tools, electric tools, etc. In daily life or in processing plants, users can often be seen using them to turn various fasteners such as screws, bolts, nuts, etc. Among them, power tools such as pneumatic tools and electric tools are more popular among users because they do not require users to drive them by themselves.

[0003] In order to meet the needs of different working spaces and working angles, power tools with relatively adjustable working heads and grips have been developed. Generally speaking, the working heads and grips of adjustable angle power tools are connected to each other through shafts and nuts. However, when the working angle needs to be adjusted, a wrench or similar tool must be used to loosen or tighten the nut. It is not possible to adjust directly, which is extremely inconvenient and affects work efficiency.

[0004] Therefore, it is necessary to provide a novel and progressive power tool with adjustable angle to solve the above-mentioned problems. Utility Model Content

[0049] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is necessary to make it clear in advance.

[0050] Please refer to Figures 1 to 6, which shows an embodiment of the utility model, the adjustable angle power tool 1 of the utility model comprises a working head 10, a grip 20, a pivot assembly 30, a disassembly member 40 and a push member 50. In this embodiment, the adjustable angle power tool 1 is a pneumatic tool, but it can also be an electric tool or other power source tool.

[0051] The working head 10 includes at least one limiting hole 11. The pivot assembly 30 includes a shaft 31 and a nut 32. The shaft 31 includes a threaded section 311 and is inserted through the working head 10 and the grip 20. The nut 32 is screwed to the threaded section 311. The disassembly member 40 is rotatably disposed on the shaft 31 and includes a sleeve hole 41. The disassembly member 40 is sleeved on the nut 32 with the sleeve hole 41 without relative rotation. The abutting member 50 elastically abuts between the working head 10 and the disassembly member 40, and can be adjusted to extend into the at least one limiting hole 11 and abut against the working head 10 to provide rotation resistance to the working head 10. In this way, the positioning between the working head 10 and the grip 20 can be locked or loosened through the disassembly member 40 without using a wrench or similar tool, so that the angle adjustment of the working head 10 can be achieved simply and quickly.

[0052] The angle of the sleeve hole 41 is greater than the angle of the nut 32, for example, the angle of the sleeve hole 41 is greater than or equal to twice the angle of the nut 32, which is conducive to the assembly of the disassembly member 40 and the configuration of various angles required. The shaft member 31 is provided with a limiter 60, which is an E-shaped buckle, a C-shaped buckle or other similar components. The disassembly member 40 is limited between the limiter 60 and the grip 20, which can effectively limit the position and facilitate assembly and disassembly. In detail, the disassembly member 40 also includes a cover 42 and at least one driving part 43, the cover 42 includes the sleeve hole 41, and the at least one driving part 43 extends radially from the cover 42. Preferably, the disassembly member 40 includes two driving parts 43 extending radially relative to each other, which is conducive to force application and driving. The disassembly member 40 also includes a spacer 44 located between the grip 20 and the cover 42, and the nut 32 is sandwiched between the spacer 44 and the cover 42. In detail, the spacer 44 is embedded with the cover 42, and the cover 42 can stably rotate around the spacer 44. Preferably, the spacer 44 includes a recessed chamber 441, and the recessed chamber 441 contains an elastic member 70, which is a spirally extending ring member (such as a spring washer). The elastic member 70 is elastically pressed between the spacer 44 and the grip 20, so that the nut 32 can be surely sleeved with the sleeve hole 41, and the elastic member 70 can be prevented from damaging the disassembly member 40 and the nut 32.

[0053] In the present embodiment, the at least one limiting hole 11 includes an arc-shaped long hole 111, and the arc-shaped long hole 111 extends in an arc shape around the axial direction of the shaft member 31. The abutting member 50 abuts against the bottom wall of the arc-shaped long hole 111. In detail, the abutting member 50 includes an elastic member 51 abutting against the spacer 44 and a push pin 52 that is elastically pushed by the elastic member 51 and abuts against the bottom wall of the arc-shaped long hole 111, thereby achieving a stepless angle adjustment effect; however, the at least one limiting hole 11 may also include a plurality of positioning recesses, thereby achieving a multi-stage and stable angle adjustment effect. Preferably, the grip 20 includes a through hole 21, and the abutting member 50 is penetrated through the through hole 21, which can stably hold the abutting member 50 and facilitate the smooth and precise movement of the abutting member 50.

[0054] Furthermore, the working head 10 further includes a first channel 12, the grip 20 includes a second channel 22, the shaft 31 further includes a third channel 33 connected to the first channel 12, and the second channel 22 and the third channel 33 are open at one side of the grip 20; the adjustable angle power tool 1 further includes a side cover 80 detachably and hermetically sealed on the grip 20, the side cover 80 covers the second channel 22 and the third channel 33, and a space 81 is defined between the side cover 80 and the grip 20, and the space 81 is connected to the second channel 22 and the third channel 33. In this way, a channel for supplying a power source required for driving rotation can be directly established outside the working head 10 and the grip 20, without forming or configuring a complex structure or component on the working head 10 and the grip 20, and the structure and components are simple, and are convenient for assembly, disassembly, replacement and maintenance.
