Perfect further, have inside groove in head capsule, in inside groove, be connected with hex nut plastic, have in hex nut plastic and be placed in interior endoporus for hex nut.Like this, this structure in use, realizes driving hex nut to rotate by hex nut plastic, not only increase usable floor area, and rotating effect is good, in quick-replaceable saw blade, provides strong help, convenient and swift.
Perfect further, inside groove opening part is provided with a circle collar, and this collar is placed on outside hex nut plastic.Like this, in use, being arranged so that hex nut plastic does not fit with the inwall of inside groove and contacting of collar, better can realize rotating effect to this structure, and arranging of collar can also play certain dustproof effect simultaneously, convenient and swift.
Perfect further, leave free gap between hex nut plastic and inside groove.Like this, this structure in use, utilizes free gap to give volute spring usage space, because volute spring can change by profile under the effect of external force, has Self-resetting simultaneously, makes result of use better, convenient and swift.
Perfect further, be provided with spring shim between spindle nose cover and soket head cap screw.Like this, this structure in use, is considered that the installing/dismounting of saw blade is comparatively frequent, therefore is adopted spring washer, not only can play locking effect, and be applicable to load and unload position frequently, with low cost, easy for installation.
Perfect further, spring is volute spring.Like this, this structure in use, consider that the diameter of spindle nose cover and output shaft is inconsistent, spindle nose cover is greater than output shaft, in order to reach the result of use of expection, therefore adopts volute spring, the end face that the size at the upper and lower two ends of volute spring and output shaft, spindle nose are overlapped conforms to, and contact with it completely, realization effect, convenient and swift.
The effect that the utility model is useful is: the fast quick change saw blade device on pendulum-type power tool of the present utility model not only can realize quick-replaceable saw blade, and make saw blade firmly be placed between hex nut and spindle nose cover by the downforce that spring applies, and it is in use highly stable, good result of use can be reached, be worthy to be popularized.
