Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a jigsaw with a protective function. Background Art

[0002] Curve saws are mainly used for cutting metals and non-ferrous metals. When cutting metals, they have stronger chip handling capabilities and larger teeth. They are more efficient when cutting wood and other wooden products. Carbon steel curve saws are used to cut various woods and non-metals. The teeth are sharpened and conical, so they cut quickly and have stronger chip handling capabilities. With the development of society, curve saws have been put into use in large quantities.

[0003] Currently, most jigsaws are often placed randomly after use. Since the saw blade of the jigsaw is exposed, the hand is likely to touch the saw blade when the jigsaw is subsequently picked up for use, or when the device is accidentally touched, which can easily cause scratches on the user's hands. This poses a certain safety hazard and needs to be improved. Utility Model Content

[0010] Preferably, the cross section of the cleaning brush is Y-shaped.

[0011] Preferably, a storage groove is provided on the surface of the machine body. After use, the pull ring can be pulled, which then drives the sliding frame to move, and the sliding frame then drives the cleaning brush to move, and the cleaning brush then cleans the debris on the surface of the saw blade. The width of the storage groove is greater than the width of the sliding frame. When storing the protective frame, the sliding frame can be stably inserted into the storage groove, thereby achieving stable storage of the protective frame and the sliding frame.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, after use, the protective frame is rotated, the main magnet is separated from the second secondary magnet, the protective frame then drives the support plate to move, the support plate then covers the saw blade, and the main magnet is then adsorbed on the first secondary magnet to perform a protective operation on the saw blade. The main magnet is only used to perform a positioning operation on the protective frame. Therefore, the protective frame can be stably positioned by the first secondary magnet and the second secondary magnet to assist the user in performing production operations. The protective device facilitates the protective operation of the saw blade to avoid the saw blade being exposed to the outside, and reduces the probability of the user's hand touching the saw blade when accidentally touching the device, thereby improving the safety of the device and facilitating the normal use of the device.

[0014] 2. In the utility model, after use, the pull ring can be pulled, and the pull ring then drives the sliding frame to move, and the sliding frame then drives the cleaning brush to move, and the cleaning brush then cleans the debris on the surface of the saw blade.
