A saw bow rack 1 is combined with a saw bow rack handle 2; a slide block mounting sleeve 5 is in fixedly riveted joint with the saw bow rack 1; a front slide block 6 is mounted in a front slide block mounting sleeve 5; a back slide block 7 is mounted in a back slide block mounting sleeve 5; and the angle of the back slide block 7 can be adjusted at60 DEG, 90 DEG and the like axially; a saw blade positioning pin 13 is in riveted joint with the front slide block 6 and the back slide block 7; a fine-tuning nut 8 is in threaded connection with theback slide block 7, and can rotate 360 DEG axially so as to adjust micro-distance between the front slide block 6 and the back slide block 7; a connecting rod fixed block 9 is connected with the fine-tuning nut 8; a connecting rod 11 is in riveted joint with the connecting rod fixed block 9 through a movable pin; a crank rotary swing handle 12 is in riveted joint with the connecting rod 11 through a movable pin, and is connected with the saw bow rack handle 2 through a movable pin; and the rotary handle 12 is moved, so as to drive the combination of the connecting rod 11 and the slide blocks,and the fast loading and unloading of a saw blade 14 can be realized by utilizing a dead point device.

Description

The fixed saw bow frame of crank block connecting rod
Technical field:
The utility model belongs to the hardware ﹠ tools class, and pincers worker is installed hand saw blade, manual sawing metal material etc. with the fixed saw bow frame of a kind of handheld tool.
Background technology:
At present, in the domestic mechanical industry, the hardware ﹠ tools Hand saw shelf that pincers worker is used, after hand saw blade is installed, the operator turns wing nut with thumb of hand and infanticide to adjust fastening saw blade, this wing nut device for screwing up, and the wing nut rotary arm is short, adjust the strength deficiency that is easy to when fastening because of hand, and the rate of tension of saw blade can't be reached.When operation sawing object, saw blade does not tightly easily cause saw blade sawtooth quick abrasion, and the sawing object does not easily reach specification requirement, and changing a saw blade needed about one minute time spent.Saw blade tightness deficiency also fractures easily, and has reduced operator's safety index, thereby wastes time and energy.
Summary of the invention:
The utility model purpose is to overcome that the saw blade tightness that above-mentioned technical deficiency causes is not enough, easy to wear, frangibility, replacing time are long etc.And a kind of quick loading and unloading saw blade is provided, and time saving and energy saving, easy to use, adjust the fixed saw bow frame of crank block connecting rod simple, that the replacing saw blade only need be finished several seconds.
Be realization above-mentioned requirements purpose, the fixed saw bow frame of crank block connecting rod, by saw frame, saw frame handle and crank rotary oscillation handle and slide block are formed.It is characterized in that: the slide block combination is installed in the rear slider installation sleeve, rear slider is threaded with fine-tuning nut, the front and back slide block can be done axial 60 °, 90 ° of equal angles adjustment, the connecting rod fixed block is connected by attachment screw with fine-tuning nut, fine-tuning nut can be made the microspur that rear slider and front-slider are adjusted in axial 360 ° of rotations, connecting rod and connecting rod fixed block are lived and are sold riveted joint, crank rotary oscillation handle and connecting rod are lived and are sold riveted joint, crank rotary oscillation handle is installed on the saw frame handle, when crank rotary oscillation handle is moved rotation clockwise, connecting rod promotes slide block sub-assembly rectilinear motion, be operating as this moment pulls down the replacing saw blade, when crank rotary oscillation handle promotes to rotate counterclockwise, and connecting rod pulling slide block sub-assembly rectilinear motion, utilize dead point device locking crank rotary oscillation handle to rotate, and the good saw blade of Fast Installation tensioning.
The utility model has adopted leverage, possesses following advantage: the loading and unloading saw blade is time saving and energy saving; The saw blade rate of tension can be by small-sized fine setting apart from the nut easy adjustment; The linearity height has reduced wearing and tearing, heating and non-frangibility after the saw blade tensioning, has prolonged saw blade service life.
Description of drawings:
Specify below in conjunction with accompanying drawing.
Fig. 1 shows the fixed saw bow frame of crank block connecting rod full view.
Fig. 2,3 shows slide block sub-assembly view and slide block parts sectional view.
Fig. 4 shows slide block connecting rod crank rotary oscillation handle aggregate motion view.
Among the figure, the 1-saw frame; 2-saw frame handle; 3-U type hole; Type hole, 4-garden; 5-slide block installation sleeve; 6-front-slider: 7-rear slider; The 8-fine-tuning nut; 9-connecting rod fixed block; The 10-attachment screw; The 11-connecting rod; 12-crank rotary oscillation handle; 13-saw blade alignment pin; The 14-saw blade.
The specific embodiment:
With reference to accompanying drawing 1, the fixed saw bow frame of crank block connecting rod is combined by following components.That is: saw bow frame 1 and saw frame handle 2 combinations are processed with U type hole 3 and type hole, garden 4 on the saw frame, be used for weight reduction with beautify outward appearance; Slide block installation sleeve 5 fixedly is riveted on the saw frame 1, front-slider 6 is installed in the front-slider installation sleeve 5 and can does axial 60 °, the adjustment of 90 ° of degree equal angles, on saw blade alignment pin 13 riveted joint front-sliders 6 and the rear slider 7, rear slider 7 is installed in the rear slider installation sleeve 5 and can does axial 60 °, 90 ° of equal angles adjustment, fine-tuning nut 8 is threaded with rear slider 7, fine-tuning nut 8 can be made the microspur that rear slider 7 and front-slider 6 are adjusted in axial 360 ° of rotations, connecting rod fixed block 9 is connected with fine-tuning nut 8, connecting rod 11 is lived with connecting rod fixed block 9 and is sold riveted joint, crank rotary oscillation handle 12 is lived with connecting rod 11 and is sold riveted joint, and is connected with saw frame handle 2 pins alive; Saw blade 14 is installed in saw blade alignment pin 13.
With reference to accompanying drawing 2,3, slide block sub-assembly view and slide block parts sectional view, saw blade alignment pin 13 fixedly is riveted on rear slider 7, and rear slider 7 is threaded with fine-tuning nut 8, connecting rod fixed block 9 is connected with fine-tuning nut 8 usefulness attachment screws 10, and fine-tuning nut 8 can be done the adjustment of axial 360 ° of rotation microspurs.
With reference to accompanying drawing 4, slide block connecting rod crank rotary oscillation handle aggregate motion view.Crank rotary oscillation handle 12 is lived in selling with saw frame handle 2 and is connected, and utilize connecting rod 11 to be connected with slide block sub-assembly Fig. 2, when crank rotary oscillation handle 12 is moved rotation clockwise, connecting rod 11 promotes slide block sub-assembly rectilinear motion, be operating as this moment to pull down and change saw blade 14, when crank rotary oscillation handle 12 promotes rotation counterclockwise, connecting rod 11 pulling slide block sub-assembly rectilinear motions, be operating as this moment saw blade 14 is installed, can carry out normal sawing object.
The fixed saw bow frame of crank block connecting rod, the laborsaving handle of a kind of employing loads and unloads saw blade fast, and promptly time saving and energy saving, saw blade rate of tension is easy to adjust simply, the replacing saw blade only needs finish several seconds, and the sawing object is difficult for the fixed saw bow frame of deflection.
