Described actuating arm 7 is provided with near tops and turns over slip-knot on unidirectional, and spinner is gone in the joystick type chamber on the afterbody, which is provided with stingy hand.

Embodiment

Referring to Fig. 1-Fig. 3, multi-functional handsaw, concrete scheme realizes in the following way: have a die cavity on handle 5, have left and right sides snapping to form.The top of this die cavity is provided with the propulsive mechanism die cavity, the bottom is provided with circular tape measure die cavity, the impelling sheet that uses in whole handle die cavity and the die cavity, step up sheet, actuating arm 7 and limited bolt 3 and lock-button 4 and all can adopt the preparation of metal material or rigid plastics, wherein die cavity can adopt die casting or injection moulding mode to realize.

Spring

17 and 18 is commercially available.

During installation, the die cavity that sheet and spring 18 and impelling sheet and spring 17 are put into propulsive mechanism successively be will step up earlier, projection piece a19, projection piece b20 and projection piece c21, lock-button 4 spacing clampings specifically passed through; The upper end of clamp clip one side is withstood on the projection piece c, and the lower end withstands on the lock-button 4; The clamp clip opposite side is supported on projection piece a19 and the projection piece b20 by spring 18; At the opposite side of projection piece a19 and projection piece b20 impelling sheet, and step up sheet and spring 18 and be installed in side by side in the handle propulsive mechanism die cavity for supporting by spring 17.Again saw bow 1 is inserted from die cavity front ecto-entad, inject die cavity after spring 17, impelling sheet, spring 18, step up sheet after, saw bow 1 stretches out from the opposite side of die cavity, loads onto the location in the termination that saw bow 1 stretches out and fastens 3; This moment, sheet formation inclined-plane blocked saw bow and actuating arm 7 is formed propulsive mechanisms 14 because projection piece c and lock-button 4 not on a vertical plane, are stepped up.
