Abstract
The transmission mechanism includes a saw blade, a slide rod connected to the back and of the saw blade, a transmission board behind the slide rod and fixed eccentrically via pinshaft on a gear, a slide sleeve outside the slide rod, a working stand connected to the front end of the slide sleeve, an L-shaped board connected to the back end of the slide sleeve and a connecting board connected to the back end of the L-shaped board and with a hole for the cam shaft of the gear to insert in. The slide rod and the transmission board are connected via a parallel ball shaft hinging mechanism, and the cam shaft has a raise direction same as the eccentric direction of the pin shaft on the gear. The transmission mechanism can simulate hand in cutting in the required direction when powdered by some drivers.

The objective of the invention is: a kind of transmission device of novel electric reciprocating saw is provided, and this device can imitate the staff action and realize in the angle of slide bar lifts to the work of the cutting direction application of force by utensil power, operates more laborsavingly, cuts more effective.
Technical scheme of the present invention is: a kind of transmission device of electric reciprocating saw, comprise saw blade, the saw blade rear end is connected with slide bar, the slide bar rear end is connected with driver plate, driver plate is fixed on the gear with bearing pin off-centre, slide bar is with sliding sleeve outward, the front end of sliding sleeve is connected with Working rack, described slide bar is connected with the parallel axes ball-and-socket hinge device with driver plate, the rear end of described sliding sleeve is connected with angle point and is fixed with L shaped seesaw, the rear end of L shaped seesaw is connected with connecting plate, connecting plate is provided with borehole jack on the camshaft of gear, and the protrusion direction of camshaft is identical with the eccentric direction of bearing pin on gear.
The further technical scheme of the present invention is: a kind of transmission device of electric reciprocating saw, comprise saw blade, the saw blade rear end is connected with slide bar, the slide bar rear end is connected with driver plate, driver plate is fixed on the gear with bearing pin off-centre, slide bar is with sliding sleeve outward, the front end of sliding sleeve is connected with Working rack, described slide bar is connected with the parallel axes ball-and-socket hinge device with driver plate, the rear end of described sliding sleeve is connected with angle point and is fixed with L shaped seesaw, the rear end of L shaped seesaw is connected with connecting plate, connecting plate is provided with borehole jack on the camshaft of gear, and the protrusion direction of camshaft is identical with the eccentric direction of bearing pin on gear; Described parallel axes ball-and-socket hinge device comprises the Y shape ball pivot head and the spherical of being located at the driver plate front end that is pinned at the slide bar rear end with bearing pin, and ball pivot head and spherical are also used the bearing pin pin joint.
The more perfect technical scheme of the present invention is: a kind of transmission device of electric reciprocating saw, comprise saw blade, the saw blade rear end is connected with slide bar, the slide bar rear end is connected with driver plate, driver plate is fixed on the gear with bearing pin off-centre, slide bar is with sliding sleeve outward, the front end of sliding sleeve is connected with Working rack, described slide bar is connected with the parallel axes ball-and-socket hinge device with driver plate, the rear end of described sliding sleeve is connected with angle point and is fixed with L shaped seesaw, the rear end of L shaped seesaw is connected with connecting plate, connecting plate is provided with borehole jack on the camshaft of gear, and the protrusion direction of camshaft is identical with the eccentric direction of bearing pin on gear; Described parallel axes ball-and-socket hinge device comprises the Y shape ball pivot head and the spherical of being located at the driver plate front end that is pinned at the slide bar rear end with bearing pin, and ball pivot head and spherical are also used the bearing pin pin joint; Also be provided with balance weight on the axle of described gear.
Advantage of the present invention is:
1. the present invention can imitate the action of staff, when saw blade is implemented effectively cutting to workpiece, exerts pressure on cut direction, makes cutting faster, more effective.
2. be connected with the parallel axes ball-and-socket hinge device between slide bar of the present invention and the driver plate, both tangible difference arranged, can realize effective cutting again with prior art.
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a front view of the present invention;
Fig. 2 is a vertical view of the present invention;
Wherein: 1 saw blade; 2 slide bars; 3 driver plates; 4 bearing pins; 5 gears; 6 sliding sleeves; 7 Working racks; 8L shape seesaw; 9 connecting plates; 10 holes; 11 camshafts; 12 bearing pins; 13Y shape ball pivot head; 14 ball pivot faces; 15 balance weights.
Embodiment: as shown in the figure, a kind of transmission device of electric reciprocating saw, comprise saw blade [1], saw blade [1] rear end is connected with slide bar [2], slide bar [2] rear end is connected with driver plate [3], driver plate [3] is fixed on the gear [5] with bearing pin [4] off-centre, the outer sliding sleeve [6] that is with of slide bar [2], the front end of sliding sleeve [6] is connected with Working rack [7], described slide bar [2] is connected with parallel axes ball-and-socket hinge device [7] with driver plate [3], the rear end of described sliding sleeve [6] is connected with angle point and is fixed with L shaped seesaw [8], the rear end of L shaped seesaw [8] is connected with connecting plate [9], connecting plate [9] is provided with on the camshaft [11] that hole [10] is enclosed within gear [5], and the protrusion direction of camshaft [11] is identical with the eccentric direction of bearing pin [4] on gear [5]; Described parallel axes ball-and-socket hinge device [7] comprises the Y shape ball pivot head [13] and the spherical [14] of being located at driver plate [3] front end that is pinned at slide bar [2] rear end with bearing pin [12], and ball pivot head [13] is also used bearing pin [12] pin joint with spherical [14]; Also be provided with balance weight [15] on the axle [11] of described gear [5].During work, Working rack [7] props up and is cut workpiece, make the front end relative fixed of connected sliding sleeve [6], during gear [5] rotation, drive driver plate [3] and connecting plate [9] simultaneously, because both eccentric directions on gear [6] are identical, therefore, saw blade [1] is forward the time, and connecting plate [9] also travels forward, and connecting plate [9] promotes L shaped seesaw [8], L shaped seesaw [8] is under the promotion of connecting plate [9], the rear end of connected sliding sleeve [6] is moved downward, saw blade [1] is lifted upward, saw blade this moment [1] does not have shear action to work, when driver plate [3] moves with connecting plate [9] simultaneously backward, saw blade [1] beginning cut workpiece, L shaped seesaw [8] moves upward the rear end of sliding sleeve [6] under the pulling of connecting plate [9], saw blade [1] is moved downward, thereby can make more effectively cut workpiece of saw blade [1], the operative employee is more laborsaving, and operating efficiency is higher.In said process, the front end of sliding sleeve [6] is equivalent to the fixed pivot of a lever, and the rear end of saw blade [1] and sliding sleeve [6] is two moving points, produces relative motion.
