The tactile switch (43) is electrically connected to the drive mechanism (2). When the trigger piece (312) touches the tactile switch (43), it triggers the braking and reversal of the drive mechanism (2) to realize the automatic return of the bending disc (31).
2. The angle adjustable bench bar bender according to claim 1, wherein: The bending mechanism (3) further includes a central shaft (32), a bending shaft (33) and a stop block (34). The central shaft (32) passes through the bending disk (31), the bending shaft (33) passes eccentrically through the bending disk (31), and the stop block (34) is disposed on one side of the bending disk (31).
3. The angle adjustable bench bar bender of claim 2, wherein: The top of the central shaft (32) is fitted with a central sleeve (321), the top of the bending shaft (33) is fitted with a bending sleeve (331), and a torsion spring (35) is fitted on the outside of the bushing (311). The two ends of the torsion spring (35) abut against the bending disc (31) and the bending machine body (1) respectively.
4. The angle adjustable bench bar bender of claim 2, wherein: The bending mechanism (3) further includes a positioning sleeve (332) and a rubber wheel (36). The positioning sleeve (332) is located at the bottom of the bending shaft (33), and the rubber wheel (36) is located on the bending machine body (1) and at the initial position of the bending disc (31). When the bending disc (31) is reset, the rubber wheel (36) abuts against the positioning sleeve (332).
5. The angle adjustable bench bar bender of claim 1, wherein: It also includes a waste removal mechanism (5), which includes a dustproof pad (51), a dustproof block (52) and a waste removal chute (53).
