Abstract
A hand-held band saw includes a band saw body and an supporting device. The supporting device includes a fixing member, a slider, a supporting member, and a connection assembly. The fixing member is fixedly connected to the band saw body, the slider is slidably connected to the fixing member, the supporting member supports a workpiece and is connected to the slider, and the connection assembly connects the slider and the supporting member. When the slider moves, the connection assembly is capable of enabling the supporting member to move along with the slider. The connection assembly comprises a buffer member mounted between the slider and the supporting member.
Claims8
A hand-held band saw, comprising:
- a housing assembly wherein a cutting area is formed in the housing assembly and a saw blade is disposed at least partially in the cutting area;
- and
- an adjustment device connected to the housing assembly and disposed at least partially in the cutting area, the adjustment device comprising a support member connected to the housing assembly, a fence member connected to the support member and configured to be slidable to a preset position relative to the housing assembly, and an elastic member disposed at least partially in the housing assembly;
- wherein the fence member is slidable relative to the housing assembly into at least a first position and the preset position, the first position is an original state in which the fence member does not extend out of the cutting area, the preset position is an extended state in which the fence member extends out of the cutting area, the fence member moves from the first position to the preset position relative to the elastic member, and, when the fence member is at the preset position and in a case where the fence member is subjected to an external force, the fence member moves basically along a first sliding direction to a third position, and the elastic member is capable of generating a biasing force opposite to a movement direction of the fence member to move the fence member to the preset position, and the elastic member prevents the fence member from being disengaged from the support member.
