Problems solved by technology
However, when the saw blade reciprocates at high speed relative to the workpiece, if the workpiece is not fixed, the friction force will cause the workpiece to vibrate or swing violently with the reciprocating motion of the saw blade, which is laborious to operate and low in cutting accuracy.
In the prior art, such as CN101758294B, US5,611,146, WO2012107253A1, etc., disclose a reciprocating saw with a clamp. Although the problem of fixing the workpiece is solved, either the structure is too complicated and the operation is not very convenient, or the clamping of the workpiece is reliable. lower sex

The invention relates to an electric reciprocating saw, which comprises a shell, a saw blade, a saw blade bracket and a main handle, wherein a work piece clamping device used for clamping work pieces is forwards arranged at the front end of the shell, the work piece clamping device comprises a base frame, a rotating stand, a lower clamping arm, a connecting arm and an upper clamping arm, wherein a movable four-bar mechanism is formed by the upper clamping arm, the lower clamping arm, the connecting arm and the rotating stand, a dynamic clamping space with a forward opening is formed by an inclined angle between a forward extension arm of the upper clamping arm and the lower clamping arm, and the work pieces of different sizes can be tightly clamped by the extension arm in the dynamic clamping space and the lower clamping arm. According to the electric reciprocating saw provided by the invention, the work pieces can be clamped through the work piece clamping device, and the electric reciprocating saw has the advantages of simpleness in operation, conformableness, high cutting precision and high working efficiency.
Description
technical field [0001] The invention relates to an electric reciprocating saw, in particular to an electric reciprocating saw with a workpiece clamping device. Background technique [0002] Electric reciprocating saw is a common tool for cutting pipes, wood and other workpieces. Its working principle is that the motor drives the reciprocating rod through the gear box to make reciprocating motion. The saw blade is installed on the reciprocating rod to perform reciprocating sawing movement on the workpiece. However, when the saw blade reciprocates at high speed relative to the workpiece, if the workpiece is not fixed, the friction force will cause the workpiece to vibrate or swing violently with the reciprocating motion of the saw blade, which makes the operation laborious and the cutting accuracy low. In the prior art, such as CN101758294B, US5,611,146, WO2012107253A1, etc., disclose a reciprocating saw with a clamp. Although the problem of fixing the workpiece is solved, eit...
