When people drill, people first hold handle 1 and the present invention are put on the timber for needing to drill, protection
Device 15 is contacted with timber, and drill bit 14 is placed in the surface of bore position, and then people pull up cross bar 11, horizontal
Bar 11 drives motor 9, shaft 12, binder 13, drill bit 14 and pull rod 10 to move up, motor 9 drive mounting base 8 and sliding block 5 to
Upper movement, the first spring 6 are stretched, and people start motor 9 and work later, and the rotation of 9 output shaft of motor drives shaft 12, binder
13 and drill bit 14 rotate, and then people again remove hand from cross bar 11, and sliding block 5, motor 9 and drill bit 14 are in the first spring 6
It can be moved down under spring-force driven dual, drill bit 14 is contacted with timber, and is drilled, and when sliding block 5 is restored in situ, is bored
First 14 get into position, and then people pull up cross bar 11 again, and then drill bit 14 is extracted out of hole, and then people can send out this
Bright to be moved to lower place the position to drill is needed to drill, air inlet net 3 can make to be aerated in the first shell 2, convenient for motor 9
Heat dissipation is conducive to protect the intact of equipment, while can prevent sawdust from entering in the first shell 2, and then protects the peace of motor 9
Entirely, baffle 7 can provide support for the first spring 6, when drill bit 14 when in use between it is longer, when wearing more serious need replacing,
People separate protective device 15 with the first shell 2, and then people can unclamp binder 13, and then carry out more bit change
14, after people replace drill bit 14, people again clamp binder 13, later again by protective device 15 and the first shell 2
It is combined together, the protection to drill bit 14 so can be realized, avoid damage of the foreign object to drill bit 14, while when drill bit 14 exists
When wrecking in boring procedure, people are protected, prevent the case where hurting sb.'s feelings, safety is higher.
When people need replacing drill bit 14, people press pull ring 156 inwardly, and pull ring 156 drives connecting rod 155 inwardly
Mobile, second spring 157 is compressed, and deformation occurs for elastic rod 151, and then be will drive hook 152 and deviate from out of groove 153, so
People can remove second housing 150 afterwards, and after people remove second housing 150, people move up hand from pull ring 156
It opens, stopping carries out pressing pull ring 156, and then pull ring 156 and connecting rod 155 are acted in the elastic force of second spring 157 and elastic rod 151
Under can set back, people carry out more bit change 14 again later, and after people replace drill bit 14, people are again inwardly
Pull ring 156 is pressed, and then moves inward hook 152, then people can load onto second housing 150, and people are again later
Hand is removed from pull ring 156, combines hook 152 with groove 153, so that the first shell 2 be connected with second housing 150
It is connected together, drill bit 14 can so be protected in second housing 150, reduce drill bit 14 because of the probability of F. O. D, it can
It is effectively protected the intact of drill bit 14, rubber pad 158 can make the first shell 2 and second housing 150 combine closer, non-slip mat
1510 the case where can preventing present invention stabilization during the work time, being not in sliding, outlet net 1511 can be kept outside first
The flowing of shell 2 and the air in second housing 150, while being entered in second housing 150 prevented also from sawdust and equipment is made
At influence.
When people drill, people first pull up cross bar 11, and then move up motor 9, the first bullet
Spring 6 is stretched, and motor 9 drives cylinder body 16 to move up, and check valve 164, which is pressurized, to be opened, and the air of lower part passes through big in cylinder body 16
Air inlet 163 and small air inlet 165 are discharged, and exhaust velocity is very fast, people pull cross bar 11 when it is lighter, be conducive to improve
The working efficiency of people, shortens working hours, and when 16 bottom of cylinder body is no longer contacted with block 167, block 167 is in elastic slice 1612
Elastic force effect under can rotate clockwise, and then block 167 blocks cylinder body 16, then prevents motor 9 from moving down, keeps away
Exempted from people always with cross bar 11 are pulled the case where, alleviate the burden of people, limited block 1611 can anti-stop block 167 rotate
Distance it is excessive, be unfavorable for people withdraw block 167, when drill bit 14 is moved to the position of drilling by people, people pull upwards
Rocking bar 169, and then drawstring 168 is pulled to the left, drawstring 168 drives block 167 to rotate counterclockwise, and elastic slice 1612 is compressed, and gear is worked as
When block 167 is separated with 16 bottom of cylinder body, cylinder body 16, motor 9 and drill bit 14 can be to moving down under the spring-force driven dual of the first spring 6
Dynamic, check valve 164, which is pressurized, closes, and big air inlet 163 is closed, and cylinder body 16 can only carry out air inlet by small air inlet 165, air inlet
Speed is slower, and then the speed for declining motor 9 is slow, advantageously reduces transient force when drill bit 14 is contacted with timber in this way,
The safety for being conducive to protect drill bit 14, is not easy to be broken off, and then drill bit 14 drills, after drill bit 14 is drilled hole, Ren Menzai
It is secondary to pull up cross bar 11, and then cylinder body 16, motor 9 and drill bit 14 are moved up, drill bit 14 is extracted out of drilling, works as cylinder body
After 16 separate with block 167, block 167 blocks cylinder body 16, and then the drilling for next time is ready.
When people are before drilling, people can be adjusted the distance of the decline of drill bit 14 by rotating nut 171, into
And the depth of drilling is controlled, when people need to bore deeper hole, people rotate counterclockwise bull stick 172, and then drive nut 171
It is rotated counterclockwise on screwed pipe 17, cushion block 173 moves up therewith, and then makes the distance between cushion block 173 and the first shell 2
Increase, so that the distance for declining drill bit 14 increases, the Kong Gengshen that drill bit 14 drills out, when people need to bore shallower hole, people
Rotate clockwise bull stick 172, and then nut 171 is driven to rotate clockwise on screwed pipe 17, cushion block 173 is therewith to moving down
It is dynamic, and then reduce the distance between cushion block 173 and the first shell 2, so that the distance for declining drill bit 14 reduces, drill bit 14 is bored
Hole out is more shallow, so can more accurately carry out the depth of control drilling, can be adjusted according to the actual needs of people, convenient
The operation of people, is not in have saved the time of people the case where drilling is repeated, improves the efficiency of drilling.
When people start motor 9, the rotation of 9 output shaft of motor drives shaft 12 to rotate, and then drives 183 turns of flabellum
It is dynamic, wind can be then generated, the sawdust that wind drills out when drill bit 14 can drill after the guiding of wind deflector 185 blows to a side
To, and then sawdust is blown off from timber, when there is barrier in the right of timber, people can rotate second housing 150, in turn
It drives curved bar 184 and wind deflector 185 to be rotated, is then changed the direction of wind derived from wind deflector 185, to reduce
The fugitive dust generated when blowing sawdust is conducive to working long hours for people, is influenced, is conducive to by fugitive dust when can reduce people's work
The health of people, protective ring 182 can protect flabellum 183, while can reduce outside to first when flabellum 183 damages
The influence of shell 2 and second housing 150 reduces loss, and when people close motor 9, flabellum 183 stops operating therewith, Jin Erting
Only blow the work of sawdust.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
