Problems solved by technology
In order to enable the user to switch the required working mode according to the needs, these electric tools are often equipped with more complicated transmission mechanisms and corresponding clutches for operation. The adjustment direction of the existing clutch is the same as the direction of making it clutch. Undoubtedly, the size of the tool is increased, and the long stroke is not conducive to the user's quick mode switching

The invention provides a clutch device which comprises a guide member, a first clutch member, a second clutch member, a rotation member and an elastic component. The first clutch member can slide relative to the guide member. The second clutch member can slide relative to the guide member. The rotation member can rotate about a first axis relative to the guide member. The elastic component comprises a first connection leg and a second connection leg, wherein the first connection leg and the second connection leg are respectively connected with the first clutch member and the second clutch member. The rotation member is provided with a first support part and a second support part. The first support part contacts the first connection leg. The second support part contacts the second connection leg. When the rotation member rotates about the first axis, the first support part drives the first connection leg to enable the first clutch member to slide relative to the guide member, and the second support part drives the second connection leg to enable the second clutch member to slide relative to the guide member. The invention further discloses a hammer with the clutch device. The clutch device has the advantages of less occupied space, less parts and low cost.
Description
technical field [0001] The invention relates to a clutch device, in particular to a clutch device for an electric hammer. Background technique [0002] Existing rotary tools can often output impact while outputting torque, for example, an electric hammer can output both reciprocating impact and torque or both at the same time. In order to enable the user to switch the required working mode according to the needs, these electric tools are often equipped with more complicated transmission mechanisms and corresponding clutches for operation. The adjustment direction of the existing clutch is the same as the direction of making it clutch. Undoubtedly, the size of the tool is increased, and the longer stroke is not conducive to the user's quick mode switching. Contents of the invention [0003] A clutch device, comprising: a guide piece, a first clutch piece, a second clutch piece, a rotating piece and an elastic element; the first clutch piece can slide relative to the guide ...
