The piece (4 〇 1 ) ( 4 〇 2 ) is easily distorted. It is true that the position: (411) and the one-way stop shaft (416) cannot be severely severe or even split by the joint. Therefore, it is necessary to further improve the existing power ratchet wrench. SUMMARY OF THE INVENTION The present invention has been made to provide a head holder for a power ratchet wrench that is resistant to deformation. ^ Based on the above object, the main technical means of the present invention is a head device of a power ratcheting tool, comprising: a grip body having a front end outer wall provided with a section of external threaded portion, and an inner peripheral wall of the front end of the body An inner ring gear is provided; and the twin gear set includes a part of the curve extending into the inner ring gear, and a plurality of planets that are only pivoted at one end of the crank shaft and are in harmony with the inner ring gear. a bearing on the outer peripheral wall of the crank ring type, wherein an eccentric output rod is protruded from the end of the crank core 5 200829380; a fixing ring having a hollow inner portion, ... screwing the external thread portion of the body & x疋The inside of the mother is provided with a front retaining edge; Tw 〇卩, forming a one-piece clamp at the front end of the fixed ring, the outer circumference of which can be worn four and the rear end of the head clamp is protruded; The edge of the head holder is provided with a flange facing the surface, and the inner peripheral wall of the space is recessed with two waters, and the group is wide: the top and the bottom of the front end are respectively provided with a coaxial head The perforations are connected to the perforations and the lower perforations; and the space is set with the ratcheting group, including The adapter is located on the outer peripheral wall of the swinging collar and is coupled with the output rod, and is disposed inside the swinging collar and the upper perforation, the lower perforation=, and the inner peripheral wall of the wearing swinging collar is provided with an internal ring gear. =Intra-shaft toothed ring meshing... The rotating shaft is partially and after implementing the above-mentioned technical means, the specific benefit obtained by the present invention is j. Since the assembly space of the head clamp seat of the present invention is set inside the head seat, it is closed. The design is only open to the end of the grip body. Therefore, the top and bottom ends of the head P-clip joint are integrally formed to greatly improve the structural strength, so as to improve the lack of distortion of the existing head clip seat, thereby prolonging the use. life. σ' [Embodiment, please refer to the first figure, the power ratchet wrench 6 200829380 provided by the present invention includes: - a grip body (10), the outer peripheral wall of the front end of the grip body (1 〇) An external threaded portion (102) is provided on the grip body (the inner end of the ι〇 end is fixed by a ring sleeve f R ^ μ~ sleeve (16), and (4) (16) is a partial protrusion grip body (10) ) The front end forms a pw\ in the inner peripheral wall of the ring ^3 ^ r Ί 〇 π , , 丄 b ) and is provided inside the grip body (10) - drive: =: not shown) 'When the power source is In the case of gas, the drive unit is (4)::: Although the power source is electricity, the drive unit is a motor, and the power that extends into the center of the inner ring (...)
