Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to a saber saw. Background Art

[0002] In industries such as woodworking, gardening and construction, saber saws are commonly used as a tool for cutting materials such as wood, plastic, and thin metal. The traditional saber saw design usually includes a saw body of fixed length and a clamping mechanism directly connected to the saw body for fixing and clamping the workpiece to be cut. However, this design has significant limitations.

[0003] The traditional clamping mechanism is directly connected to the saw body. Although this design is stable, it lacks sufficient flexibility when it is necessary to quickly replace the saw blade or adapt to workpieces of different sizes. In addition, when the saw body or clamping mechanism needs to be replaced, a whole new saber saw needs to be purchased, which increases the cost of use.

[0004] In order to solve this problem, some designers began to try to design the clamping mechanism to be detachable to improve the flexibility and versatility of the saber saw. However, the design of the detachable clamping mechanism also brought new challenges. How to achieve a firm connection and quick disassembly between the clamping mechanism and the saw body has become a key issue. Although traditional locking mechanisms such as screws can achieve fixation, the operation is cumbersome and requires additional tools to operate, which increases the inconvenience of use.

[0005] Based on this, the applicant proposed a saber saw to solve the above technical problems. Utility Model Content
