Description

M263192 4. Creation Description (1) [Technical Field to which the New Type belongs] This creation is about a ratchet-oriented structure, especially a new structure designer who uses the innovative structure to achieve the original ratchet effect. [Previous technology] According to the press, the ratchet structure is a structure for modulating the direction of the latch. Since it allows the user to determine the direction of the latch and idling according to the needs, it can easily turn the lock such as a nut and bolt. As a result, it is widely used in various hand tools. Generally known hand tools require one-way rotation during work to rotate and disassemble workpieces, but these structures are easy to cause in use. The latch ratchet is not accurate, and it is easy to jump teeth and cannot form one-way rotation. At the same time, it will cause the positioning of the latch mechanism to loose during work, and lose the effect of one-way rotation, so that it cannot be disassembled and assembled. Cause considerable confusion. [New content] The main purpose of this creation is to provide a ratchet directional structure, which uses a brand-new component to construct a ratchet structure different from the conventional design, so as to reach a structural designer with reliable operation and easy adjustment. The structure includes a tool rod, a base, a stretcher, a cymbal, a ratchet seat, an abutment piece and an outer cover. Among them, the tool rod is fixedly provided with a base and an outer cover, and is surrounded by the base and the outer cover. The baffle, reed, ratchet seat and abutment are provided in the space, and the improvement focuses on: The base is provided with a receiving groove, and the groove is provided with an axial hole axially opposite to the tool rod, and the receiving recess is Two grooves are arranged opposite to the groove surface for placing the blocking piece and an elastic reed;

M263192 IV. Creation instructions (2) The ratchet seat is provided with ratchet teeth on the seat surface relative to the base, and a shaft hole is provided in the center of the seat surface to be embedded with the tool rod; the abutment plate conforms to the base receiving recess. The sheet body formed by the groove; the center of the outer cover is provided with a perforation, and two opposite abutments are convexly arranged on the inner peripheral surface of the cover; The abutment piece is opposed to the base cover to position the second baffle, and the ratchet seat is covered with its ratchet relative to the seat. The ends of the second baffle are adapted to abut the opposite tooth surfaces of the ratchet, respectively. The cover is opposed to the base cover, and the second stopper on the inner periphery of the outer cover is appropriately extended on the two sides of the second baffle, and with the rotation of the outer cover, the first stopper is forced to abut one of the baffles to retreat from the ratchet tooth surface. , So that the tool rod and the ratchet seat can rotate in one direction relative to the base. In this way, this creation can adjust the rotation direction of the ratchet seat by adjusting the steering of the cover, and use the simplified structure design to control the one-way rotation surely without causing idling or inaccurate movement. [Embodiment] As shown in the first figure, the creative system includes a tool lever (1), a base (2), a blocking piece (3), a reed (4), a ratchet seat (5), and an abutment piece (6 ), Steel ball (7), track plate (8), outer cover (9), where: the tool rod (1) is provided with cogs (1 1), and is opposite to the cogs (1 1) above and below A buckle groove (1 2) (1 3) is respectively provided on the periphery of the rod; a receiving groove (21) is recessed on the surface of the base (2), and is opposite to the tool rod on the receiving groove (2 1) surface (1) A shaft hole (2 2) is axially opened, and a convex rim (23) of nearly ninety degrees is protruded on the inner peripheral edge of the receiving groove (21), and
