Abstract

The invention relates to a saw blade clamping device, in particular to a saw blade clamping device which is applicable to a back-and-forth cutting tool; the saw blade clamping device comprises a locking bar and a locking sleeve which is sleeved on the locking bar and can rotate relative to the locking bar; a steel ball is arranged on the locking bar or the locking sleeve, and the locking sleeve or the locking bar is provided with a groove which rolls with the steel ball and extends in a peripheral direction; and a stopping part which stops the steel ball from rolling extends in the groove in a radial direction. According to the saw blade clamping device provided by the invention, the steel ball and the groove which can be matched are arranged between the locking sleeve and the locking bar, the steel ball rolls in the groove so that the locking sleeve and the locking bar rotate relatively, simultaneously the groove is provided with the stopping part which extends in the radial direction and can stop the steel ball from rolling, so that the rotation angle of the locking sleeve relative to the locking bar can be effectively limited, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to a saw blade clamping device, in particular to a saw blade clamping device suitable for a reciprocating cutting tool. Background technique [0002] Jigsaw is one of the common power tools for cutting. It mainly drives the saw blade to reciprocate through the reciprocating rod to cut the workpiece. According to different cutting requirements, such as cutting different materials, different saw blades are required. Therefore, a device is required to clamp the saw blade while the jigsaw is working and to easily replace the saw blade. At present, various saw blade clamping devices have appeared. A common saw blade clamping device includes a reciprocating rod and a locking sleeve set outside the connecting end of the reciprocating rod saw blade. The locking sleeve is provided with a saw blade insertion port, and the hollow connecting end of the reciprocating rod saw blade is provided with a V for clamping the lugs of the saw blade. W...
