[Prior Art] According to the convenience of using a ratchet wrench in many industries, the first figure uses a ratchet wrench (10) which rotates the trigger body (11) to thereby move the ratchet head located on the outer side (12). ), to drive the workpiece according to the set one-way. As shown in the second figure, another type of ratchet wrench (20) is used which uses the trigger body (21) to drive the outer ratchet sleeve (22) to drive the workpiece. However, the ratchet wrench used in the previous review, when driving the workpiece, must swing the wrench back and forth in order to smoothly rotate the workpiece. However, in many narrow environments, there is no space for the wrench to reciprocate. It is simply not available, and there is still room for improvement because it is not perfect. The reason is how to use the characteristics of the wrench for some small spaces and improve it, which is the subject of the creation. [New content] The main purpose of this creation is to provide a ratchet wrench structure improvement, which has the effect of being used in a narrow space, and it is possible to rotate the ratchet sleeve at the outer end to disassemble the workpiece without reciprocating the flip member. , to achieve the convenience of use. Another object of the present invention is to provide a ratchet wrench structure improvement, which can be provided with a ratchet sleeve at one or both ends for the convenience of handling. M363365 In order to achieve the above objectives, the technical means adopted in the creation include: a body having a space for a plurality of gears and a shaft hole; and two rigid cover sheets which are symmetrical and respectively disposed on the body Above and below, and the outer end of the rigid cover sheet is provided with a pivot hole, and a plurality of ZZ printing holes are provided therein; a ratchet sleeve is in the form of a hollow sleeve, and the upper and lower ends thereof are The pivot is pivotally disposed on the shaft hole of the rigid cover sheet, and the middle portion is in a ratchet type; a plurality of gears are positioned between the body and the rigid cover sheet by a plurality of corresponding shaft columns to make each other The outer gear train is in a twisted shape, and when the inner gear is toggled, the ratchet sleeve at the outer end is linked in the same direction. [Embodiment] First, referring to the third to seventh figures, the ratchet wrench (90) of the first embodiment of the present invention comprises: a body (30) on which a plurality of gears are provided (60). The installation space (31) and the shaft hole (32); the two rigid cover sheets (40) are symmetrically disposed above and below the body (30), and the rigid cover sheet (40) The outer end portion is provided with a boring shaft hole (41), and a plurality of rivet holes (42) are provided therein; a ratchet sleeve (50) is in the form of a hollow sleeve, and the upper and lower ends are 柩-axis ( 51) and pivoted to the pivot hole (41) of the rigid cover sheet (40), and the middle portion is in the form of a ratchet (52); a plurality of gears (60), by a plurality of corresponding shaft columns (61) The inner body (30) and the rigid cover sheet (40) are positioned to be chewed to each other, and the outer gear train is coupled with the ratchet wheel (52), and the inner gear M363365 (6) 〇) When the toggle is made, the ratchet sleeve (50) at the outer end is linked in turn. Each of the previously disclosed components is positioned by riveting the rigid cover sheet (40) with the shaft post (61), but the length of the middle portion of the shaft post (61) is slightly larger than that of the middle member so that it is not jammed. And the body is still rotatable. The body (30) corresponds to the end of the ratchet sleeve (5〇), and the groove (33) is provided with a spring (?!) and a steel ball ( π), and a ratchet claw (73) is pivoted between the groove (33) and the ratchet wheel (52), thereby forming a ratchet one-way control assembly (7〇). Furthermore, as shown in the fifth figure, the two rigid cover sheets (4 〇) include a "over the outer cover (8 〇)' and the outer cover (8 〇) is provided with a hollow at a predetermined position. Hole (81) for the inner member to be exposed. In addition, the plurality of gears (6〇) included in the front cover include a larger outer diameter gear (60'), and the outer edge thereof protrudes from the outer hole (81) of the outer cover (81), which is convenient for the user. Use your finger to transfer. As shown in the first, seventh, and seventh figures, the schematic diagram of the operation of the embodiment is shown, that is, the user can use the finger to dial the innermost gear (60,) to rotate, and when the gear is not moving, (60) When the total number of ratchets (52) is an odd number (five in this embodiment), the innermost gear (6〇,) must be rotated in the same direction as the outermost ratchet (52), and the ratchet sleeve is smoothly driven ( 5〇) Turn to drive the workpiece. The eighth figure is a schematic view of the second embodiment of the present invention. The rigid cover sheet (4〇) includes pivot holes at both ends (not shown in Fig. 8, see the previous embodiment), and the pivot holes at the two ends. A ratchet sleeve (50) is mounted, and the total number of the gear (6〇) and the two ratchets (52) is an odd number (9 in this embodiment). In this way, when the ratchet sleeve (50) at the side of the inner M363365 is turned by the user with a tool or a finger, the outermost ratchet sleeve (50) can be rotated in the same direction to smoothly disassemble the workpiece. The ninth drawing is a schematic view of a third embodiment of the present invention. The rigid cover sheet (40) is provided with a shaft hole and a ratchet sleeve (50) at one end and a fixed wrench (43) type at the other end. Thereby, the ratchet wrench (90) of the present invention can be made with a ratchet sleeve (50) at one end or two ends, and the ratchet sleeve of one end of the same direction can be rotated by rotating the trigger body without rotating the trigger body. The assembly of the workpiece is especially suitable for operators in small spaces. In summary, the structure revealed by this creation is unprecedented, and it can achieve the improvement of efficacy, and it can be used for industrial utilization. It fully complies with the new patent requirements, and invites your review committee to grant patents. Innovation, no sense of morality. However, the above-mentioned drawings and descriptions are only preferred embodiments of the present invention. Modifications or equivalent changes made by those skilled in the art in accordance with the spirit of the case should still be included in the scope of the patent application.
