[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the reciprocating saw joint of the present invention moves the movable ring backward through the fixing assembly to move the limit block in the limit groove. When the limit block moves to the other side of the limit groove, the movable ring continues to move. At this time, the movable ring applies a pulling force to the connecting rod, so that the connecting rod pulls the connecting seat, driving the movable block to open outward, so that the clamping block is separated from the clamping plate, and the saw blade can be removed. A new saw blade is placed at a designated position, and the movable ring is pushed forward to make the movable ring contact with the movable block. During the movement of the movable ring, the movable block is pushed to close. At the same time, the connecting rod gradually moves to the innermost side of the limiting groove, and finally the movable ring fixes the movable block to complete the replacement. Compared with the current existing technology, since the joint of the reciprocating saw is usually fixed by a fixing screw when connected to the saw blade, and the fixing screw needs to be installed with the help of tools when in use, the connection process between the joint and the saw blade is relatively cumbersome and complicated, time-consuming and labor-intensive, and inconvenient for the installation and replacement of the saw blade. This reciprocating saw joint can quickly and conveniently connect the joint to the saw blade, saving time and labor and facilitating the installation and replacement of the saw blade.

[0018] 2. Compared with the prior art, this reciprocating saw joint uses a spring, a stopper and a guide groove. When the movable ring is moved, the stopper is pressed downward to make the stopper drop. During the rearward movement of the movable ring, the stopper contacts the guide groove and is retracted into the stepped hole under the influence of the guide groove, so that the movable ring can move backward smoothly to replace the saw blade. After the replacement is completed, the movable ring moves forward, and when the stopper contacts the guide groove again, the stopper rises under the push of the spring. When the movable ring moves to the front end, the stopper completely rises, blocks the movable ring and fixes it, thereby limiting the movable ring. After the connection is completed, the movable ring is fixed to facilitate the use of the saw blade. BRIEF DESCRIPTION OF THE DRAWINGS
