Abstract
The invention provides a multi-functional electric tool and relates to the field of mechanical and electronic products. One end of a rotating sleeve is connected with a large gear in a sleeving mode; the other end of the rotating sleeve is connected with a rest spring in a sleeving mode; a sliding sleeve is connected between the large gear and the reset spring in a sleeving mode; a plurality of grooves are uniformly formed in the outer wall of the sliding sleeve; one end of the sliding sleeve is connected with a pin shaft sleeve; a pin shaft is arranged in the pin shaft sleeve; a compression spring is arranged between the front end of the pin shaft and the corresponding inner wall of the pin shaft sleeve; one end of a sliding plate is provided with a convex platform which is meshed with one of the grooves; the sliding plate is provided with a rotary knob which is connected with a handle. According to the multi-functional electric tool, the structure is simple, the machining is easy, the price is low, the large torque and vibration can be born, the multi-functional electric tool is safe and reliable and not easy to fracture, and the assembly and maintenance is simple.
Description
Technical field:
The present invention relates to electronic product field, be specifically related to a kind of multi-functional electric tools with functions such as hammer, hammer drill, brills.
Background technology:
Traditional multi-functional electric tools, when realizing single hammering, must control the rotation of driving member, under the effect of additional torsion, can not have relative rotary motion with instrument, generally adopt now tooth plate part, it is fixed in shell, by sliding sleeve, to the gear being connected, throws off rotation with turning set, and its tooth is snapped onto in the profile of tooth of tooth plate, old fixedly rotating freely of turning set, this structure has the following disadvantages:
1, tooth plate is complex-shaped, requires to match with tooth-formation of gear.
2, due to complex-shaped, material and heat treatment requirements are high, and cost is high.
3, material and heat treatedly require highly, otherwise meets larger external force frangibility or broken teeth.
4, it is generally fixed in housing, and housing is darker, is not easy to install and maintenance.
Summary of the invention:
The object of this invention is to provide a kind of multi-functional electric tools, its simple in structure, easy processing, cheap, can bear larger torsion and vibration, safe and reliable, and not easy fracture, and assembling and maintenance are simple.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises handle 1, slide plate 2, knob 3, turning set 4, gear wheel 5, sliding sleeve 6, pin sleeve 7 and back-moving spring 8; One end socket gear wheel 5 of turning set 4, the other end socket back-moving spring 8 of turning set 4, and be socketed sliding sleeve 6 between gear wheel 5 and back-moving spring 8, on the outer wall of sliding sleeve 6, be evenly provided with several groove 6-1, one end of sliding sleeve 6 is connected with pin sleeve 7, in pin sleeve 7, be provided with bearing pin 7-1, between the front end of the bearing pin 7-1 inwall corresponding with pin sleeve 7, be provided with Compress Spring 7-2, one end of slide plate 2 is provided with boss 2-1, boss 2-1 and groove 6-1 engagement, slide plate 2 is provided with knob 3, and knob 3 is connected with handle 1.
Described groove 6-1 is the axial notch being evenly distributed on sliding sleeve 6 outer walls.
Described bearing pin 7-1 and groove 6-1 match.
Described back-moving spring 8 is for the reset to sliding sleeve 6.
The present invention's processing simple in structure, easy, cheap, can bear larger torsion and vibration, safe and reliable, and not easy fracture, and assembling and maintenance are simple.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
With reference to Fig. 1, this concrete enforcement by the following technical solutions: it comprises handle 1, slide plate 2, knob 3, turning set 4, gear wheel 5, sliding sleeve 6, pin sleeve 7 and back-moving spring 8; One end socket gear wheel 5 of turning set 4, the other end socket back-moving spring 8 of turning set 4, and be socketed sliding sleeve 6 between gear wheel 5 and back-moving spring 8, on the outer wall of sliding sleeve 6, be evenly provided with several groove 6-1, one end of sliding sleeve 6 is connected with pin sleeve 7, in pin sleeve 7, be provided with bearing pin 7-1, between the front end of the bearing pin 7-1 inwall corresponding with pin sleeve 7, be provided with Compress Spring 7-2, one end of slide plate 2 is provided with boss 2-1, boss 2-1 and groove 6-1 engagement, slide plate 2 is provided with knob 3, and knob 3 is connected with handle 1.
Described groove 6-1 is the axial notch being evenly distributed on sliding sleeve 6 outer walls.
Described bearing pin 7-1 and groove 6-1 match.
Described back-moving spring 8 is for the reset to sliding sleeve 6.
During this concrete implementation and operation, to list, hammer handle 1 into shape direction rotation, handle 1 drives knob 3, knob 3 drives slide plate 2 motions, boss 2-1 promotes groove 6-1, sliding sleeve 6 is slided on turning set 4, when sliding sleeve 6 is thrown off gear wheel 5, bearing pin 7-1 is inserted in groove 6-1, if sliding sleeve 6 and bearing pin 7-1 are in non-groove location, bearing pin 7-1 extruding Compress Spring 7-2 moves forward and steps down for sliding sleeve 6, in case pushing away motionless groove 6, limited slip plate 2 make handle 1 rotation not in place, bearing pin 7-1 is under the effect of Compress Spring 7-2, be easy to be inserted in groove 6-1, bearing pin 7-1 fixes the direction of rotation of sliding sleeve 6, and sliding sleeve 6 is connected with turning set 4, turning set 4 direction of rotation are fixed, thereby while realizing single hammer work, working head and cutter, the object that shovel does not rotate.
This concrete enforcement simple in structure, easy processing, cheap, can bear larger torsion and vibration, and safe and reliable, not easy fracture, and assembling and maintenance are simple.
