[Background technology]

[0002] Conventional driver rotation structures are disclosed in, for example, Patent Document 1 and Patent Document 2.

[0003] The "ratchet direction changing structure of a ratchet tool" of Patent Documents 1 and 2 comprises a base, two engagement members, an elastic member, a direction changing ring member, and a ratchet member.

[0004] A positioning portion is provided at one end of the base. An open tank is formed on the peripheral side of the positioning portion, and an inwardly recessed arc surface is formed. A U-shaped tank is recessed at the center of the arc surface, and storage tanks are formed at appropriate distances on both sides of the U-shaped tank. The opening direction of the storage tank is the same as that of the U-shaped tank.

[0005] The two engaging members are engaged in the respective ones of the plurality of storage tanks.

[0006] The elastic member is positioned within the U-shaped groove and elastically pushes the multiple engaging members apart.

[0007] The direction-changing ring member is fitted onto the positioning portion. At least two positioning grooves are recessed on the inner circumference of the direction-changing ring member, and a positioning group is fitted between the positioning grooves and the positioning portion. At least two stop blocks are provided on the inner circumference surface of the direction-changing ring member. The engagement members are located between the stop blocks. When the direction-changing ring member rotates in one direction, one of the engagement members is rotated at a predetermined angle around the receiving groove.

[0008] The ratchet member is fitted onto the positioning portion and overlaps the direction-changing annular member. The ratchet member has teeth on an inner surface thereof that mesh with the plurality of engagement members.

[0009] However, the conventional driver rotation structure has the following disadvantages (1) and (2). (1) As shown in Fig. 5 of Patent Document 2, a ratchet member 80 is assembled onto a cover plate 70 via a C-shaped ring 82. The cover plate 70 is assembled onto a base 50 via a screw 73, and structurally, the ratchet member 80, the C-shaped ring 82, the cover plate 70, the screw 73, and the base 50 are assembled together. The ratchet member 80 is assembled with the base 50 in an indirect state. The assembly tolerance between the ratchet member 80 and the base 50 is large. (2) As shown in Fig. 6B of Patent Document 2, a torsion spring 55 is housed in a U-shaped tank. The torsion spring 55 is restricted by a screw 73, and the elasticity of the torsion spring 55 pushes the engaging members apart. The torsion spring 55 has a fine iron fork structure with two branches. Since the contact area of ​​the torsion spring 55 is very small, it slides easily, and the contact becomes uncertain due to displacement, which may result in a decrease in the pressing force of the torsion spring 55.

[0010] The present inventors have conducted extensive research in light of the shortcomings of the above-mentioned conventional driver rotation structures, and as a result have completed a driver rotation structure that can improve upon the problems of the conventional technology.

The structure of the engaging member 31 does not need to include the first control part 313.

[0038] The driver rotation structure according to the present invention has the following advantages (1) to (9). (1) The driving member 20 is pivotally mounted on the fixed base 10. The driving member 20 is hooked onto the engaging member 70. The fixed plate 60 is pivotally mounted on the fixed base 10. The fixed plate 60 is brought into contact between the first pressing surface 172 and the second pressing surface 182. The control member 50 is brought into contact between the fixed plate 60 and the driving member 20. The engaging member 70 is brought into contact between the fourth storage tank 15, the annular groove 23, the control member 50, and the fixed plate 60. The fixed base 10, the driving member 20, the control member 50, the fixed plate 60, and the engaging member 70 are in an interlocking relationship, providing a preferable assembly and pivot structure. (2) The driving member 20 is fitted onto the fixed seat 10. The engaging block 72 can be engaged with the annular groove 23. The driving member 20 is restricted by two engaging members 70. The driving member 20 can be pivotally mounted on the fixed seat 10. (3) The engaging member 70 is restricted by the first side surface 152, the second side surface 153, the control member 50 and the fixed plate 60. The third pressing surface 73 does not drop into the recess 151. The engaging block 72 has no displacement space. The driving member 20 is pivotally mounted on the fixed seat 10 and is prevented from coming off the fixed seat 10. (4) After the fixed plate 60 is pivoted on the fixed base 10, the driving member 20, the engaging group 30, the control member 50, the fixed plate 60 and the engaging member 70 are assembled on the fixed base 10 to prevent disengagement. The driver rotation structure forms a modular structure that can be transported to other places to install the grips and prevent disengagement when transported. (5) The limiting portion 17 is inserted into the pivot hole 61. A plurality of limiting blocks 171 are inserted into the plurality of limiting chambers 62, and the fixing plate 60 can be attached or detached from the fixing base 10 by rotating the fixing plate 60 to align and shift the positions of the plurality of limiting chambers 62 and the plurality of limiting blocks 171. This assembly method can be easily and quickly performed, and no tools are required for disassembly. (6) The locking block 32 is combined with the engaging member 31. The locking block 32 is pivotally mounted in the second housing tank 13. The engaging member 31 is housed in the first housing tank 11 and pivotally mounted on the first pivot portion 12. The engaging group 30 may be longer. The engaging member 31 engages the driving member 20 with the engaging block and controls the rotation by the control member 50. The engaging member 31 and the locking block 32 can each play their own role. (7) Since the engaging member 31 has the first connecting portion 314 that is assembled with the second connecting portion 323 of the locking block 32, when the control member 50 is rotated, one of the second control portions 321 comes into contact with one of the third control portions 53, and the engaging member 31 can be rotated slightly to disengage the meshing portion 311 from the ratchet portion 22. The contact structure of both the third control portion 53 and the second control portion 321 can be controlled almost reliably. (8) One side of each engaging member 31 is provided with an interlocking portion 311. The interlocking portion 311 includes a plurality of interlocking teeth. The first elastic member 40 applies a biasing force between the two engaging members 31 and the wall surface of the third housing tank 14, and each interlocking tooth of the interlocking portion 311 interlocks with the ratchet portion 22. Since the interlocking portion 311 and the driving member 20 are interlocked with each other by a large number of teeth, the driver rotation structure has a high rotation torque. (9) The first elastic member 40 has a spring structure. The first elastic member 40 abuts between the two abutment blocks 315. The abutment area of ​​the first elastic member 40 is larger than the conventional fulcrum-like abutment range. [Explanation of symbols]
