AI Technical Summary
The pressing direction of the shaft locking mechanism of existing power tools is inconsistent with the gripping direction, which makes operation inconvenient and affects the comfort of changing saw blades.
Design an axle lock structure in which the pressing component is converted into axial movement through the inclined surface of the transmission component, so that the pressing direction is consistent with the gripping direction of the hand. The elastic component provides the restoring force, and the transmission component moves linearly on the inclined surface to complete the axle lock function.
It improves operating comfort, facilitates saw blade replacement, ensures that the pressing direction is consistent with the hand grip direction, and enhances operational convenience.

Abstract
Claims
1. A shaft lock structure of a power tool including a housing and an output shaft provided in the housing, a transmission gear, characterized by, The shaft lock structure includes: A pressing component rotatably connected to the housing, the pressing component comprising a transmission section and a pressing section; A transmission component that abuts against the transmission section, wherein an elastic element is provided between the transmission component and the housing; A second transmission component is in contact with and cooperates with the first transmission component. The second transmission component has an elastic element 2 between itself and the housing. The second transmission component can move radially along the transmission gear and restrict the rotation of the transmission gear. The pressing component drives the first transmission component to move under the action of external force, which in turn causes the first transmission component to drive the second transmission component to move.
2. The shaft lock structure of a power tool according to claim 1, characterized in that: The surfaces in contact between transmission component one and transmission component two are inclined surfaces.
3. The shaft lock structure of the electric power tool according to claim 2, wherein the shaft lock structure is configured to be capable of switching the shaft lock structure between the locked state and the unlocked state by the operation of the switch. The second transmission component can perform a reciprocating motion parallel to the radial direction of the transmission gear. 4. The shaft lock structure of the electric power tool according to claim 1, wherein: the shaft lock structure is provided with a plurality of the shaft lock members. The first elastic element is used to provide the elastic force for the first transmission element to reset, and the second elastic element is used to provide the elastic force for the second transmission element to reset. 5. The shaft lock structure of a power tool according to claim 1, characterized in that: The housing includes an upper housing and a lower housing, the upper housing being used to accommodate the saw blade and the lower housing being used to accommodate the shaft lock structure.
6. The shaft lock structure of the electric power tool according to claim 5, wherein the shaft lock structure is configured to be capable of being switched between the locked state and the unlocked state by the operation of the switch. 6 The pressing section extends to the outside of the lower housing and is close to the side of the upper housing.
7. The shaft lock structure of the electric power tool according to claim 1, wherein the shaft lock structure is provided with a plurality of the shaft lock members. A connecting body is provided on one side of the transmission section. The connecting body is connected to the housing and is connected to the transmission section via a shaft. 8. The shaft lock structure of a power tool according to claim 1, characterized in that: The transmission gear has a slot on its end face facing the output shaft, and the slot is for the transmission component 2 to pass through.
