That is, when one of the aforementioned two members is rotatable and the other is unable to rotate, twisting the former can cause the latter to make a linear displacement along the screwing axis. 10 For example, the conventional bow saw (1) shown in the first figure is provided with the aforementioned adjusting mechanism (10) on its grip (2) to tighten the saw blade; the adjusting mechanism (10) is A knob (11) and a forward and backward piece (12) are formed. The knob (11) is ring-shaped, and the space is a screw hole (111), which is arranged on the handle (2) in a rotatable manner; The advancement and retreat piece (12) has a threaded shaft (121), which is provided in a non-rotatable manner 15 on the grip (2) and screwed into the screw hole (111) of the knob (11). When the knob (11) is rotated ), The advancement and retreat piece (12) is linearly displaced along its screwed axis (horizontal in the figure). In the aforementioned conventional linear advance and retreat mechanism, the rotation axis of the component to be twisted and the direction of movement of the forced forward and backward component are coaxial, so there are often many restrictions on the design and application of the 20 mechanism. Take the hand bow saw (1) in the first figure as an example. In the hand bow saw (1), the grip (2) is slightly inclined forward. It is intended to make the operator more consistent The ergonomic angle grips and operates the hand bow saw (1); however, based on the foregoing restrictions, the axis of the knob (11) in the adjustment mechanism (10) is coaxial with the direction of displacement of the advancement and retreat (12) ( The continuation page of the figure (please note and use the continuation page when the invention description page is insufficient), in other words, the circular surface of the knob (11) is perpendicular to the direction of displacement of the advancement and retreat (12), so that the knob ( 11) The exposed part for twisting and the tilted frame of the grip (2) create an uncoordinated feeling, and the gesture is not ergonomic when the operator twists. 5 In short, when the conventional advance and retreat mechanism is used, the circular surface of its knob must be perpendicular to the displacement direction of the advance and retreat parts. [New content] Therefore, the main purpose of the present invention is to provide a linear advance and retreat adjustment mechanism, in which the axis of the knob and the advance and retreat parts may not be coaxial, so that the designer can set the relative of the two components more freely when designing Angle to match the appearance of the application or make the overall appearance more coordinated and beautiful, and make the user's operation more convenient and convenient.
