Let the air flow into the assembly core (302), drive the actuating motor group (33), and rotate the output shaft (; the star-shaped tooth reduction on the ΓΓ output shaft (3 3 2) rotates extremely fast, so the planetary gear is killed The group (3 4) decelerates, 仃 (3 == 3 4 2), the output wheel (332), the teeth (333) are condensed, and the turntable (34i) 3 4 1) is moved. The shaft disk (the shaft (35) rotates to make the front end output: turn the 'crank to make the adapter ...', ^ 5 1) eccentrically rotate, and the transfer hub (4 1 4) drives the swinging collar (4 1 i) Rotate and swing to M260365 so that the one-way limit rotation shaft (4 1 6) is used to lock the ratchet part (4 i 2) of the swing collar through the one-way clamp (4 1 8) to achieve the swing sleeve. % (4 1 1) rotates to cover and rotate intermittently unidirectionally. The conventional pneumatic ratchet wrench has a separate design between the crank shaft and the turntable of the planetary reduction gear set, so that the overall design The torque increases the space, including the length of the head and the actuating motor unit. This design causes two major disadvantages: 1. The overall length is longer, which makes it difficult to operate in narrow spaces. 2. The crank shaft and the planet The turntable of the reduction gear set is of a separate design, with many parts and parts that make assembly difficult. [New content] Because the conventional ratchet wrench has a too long overall length, it has disadvantages that are not conducive to the use of narrow spaces and the assembly of U. This creative provides _ A mini ratchet wrench that facilitates operation in a narrow space and solves the above problems. In order to achieve the above purpose, this creation includes: > Shanyi grip body, a grip plate is pivotally arranged on the outer peripheral wall of the grip body, and is provided in month J A ring sleeve with an inner wall forming a tooth portion is sighed at the end, and a bearing sleeve with a bearing is provided at the front end of the ring sleeve. An intake valve group, a switch group, and an actuating motor are sequentially arranged forward from the rear end in the grip body. And the crankshaft, in which the switch group is controlled by the push-pull plate, the actuating motor group shaft center position ih, the output pumping end forms a tooth and extends into the In the sleeve, 'the crankshaft is arranged in the ring sleeve and pivoted through the bearing sleeve, a turntable is formed at the M260365 end of the crankshaft, and a number of planetary gears are pivotally arranged at equal intervals on the rear end surface of the turntable.' Engage the teeth of the output shaft, another knife]. The teeth of the inner wall of the ring ring sleeve 'the front end of the crank shaft is extended to form an eccentric output rod; and a head, the head is combined with the front end of the grip body A ratchet actuating group is provided. The ratchet actuating group includes a one-way limit rotation shaft and a swinging collar. The inner wall of the swinging collar is provided with a ratchet portion and is arranged in the head. The swinging sleeve is close to the percentage. An end of the crank shaft is provided with a receiving portion, and an adapter is provided therein. The adapter forms a perforation so that the output shaft of the crank shaft is pivoted and connected. The one-way limit rotation shaft is accommodated in the swing sleeve. The ring ratchet part is correspondingly provided with a one-way clamping member. Che Fujia ’s original book, which was created on the crankshaft ’s turntable, has three planetary gears. In the use of this creation, an air pressure source is connected to the intake valve group, and the switch of the switch group is controlled by a trigger plate, so that the airflow flows into the driving motor group to rotate the output shaft, and the output shaft rotates to rotate the planetary gear meshing with its teeth. , And then drive the turntable of the crankshaft to rotate, and the output rod at the front end of the crankshaft rotates eccentrically when it is rotated, so that the adapter it is worn to drive the swing collar to swing overly, so that the one-way limit rotation shaft therein The one-way card is used to lock the ratchet part of the swing collar, so as to achieve intermittent one-way rotation as the swing collar swings over and over. Because the turntable is integrally formed by the crank shaft, and then the planetary gears are pivoted, the overall design space of this creation can reduce the length of the head and the motor and maintain a certain torque, which makes this creation have the following advantages: M260365 1 As the overall length can be shortened, this creation is easy to operate in a small space. 2.

The ratchet actuating group (2 1) includes a swinging collar (2 1 1) and a one-way limit rotation shaft (2 16), wherein the swinging collar (2 1 1) is in the shape of a drop and is located between the two extension pieces of the υ-shaped assembly (2 0 1), and forms a ratchet part on the inner wall (2 12) 'The swing sleeve is bad (2 11) is close to the crank A C-shaped accommodating portion (2 13) is formed at one end of the shaft (14). A adapter (2 14) is housed, and the adapter (2 1 4) is bean-shaped and forms a perforation (2 15). The adapter (2 1 4) is provided with a perforation (2 1 5). The output shaft (1 4 3) of the crank shaft (1 4) is passed through, wherein the one-way limit rotation shaft (2 1 6) is passed through the two accommodation holes provided in the u-shaped assembly portion (201) and The ratchet part (212) of the swing collar (2 1 1) is axially positioned in the swing collar (2 1 1) with a C-shaped buckle (2 2), and one end of the swing collar (2 1 7) ) And corresponding to the ratchet part (2 1 2) of the swing collar (2 1 1) to form a one-way latch (2 18).
