Description
Technical field
The present invention relates to hardware tool apparatus and method and technology fields, are anti-skidding screw wrench and taking-up more specifically
The method of wood screw.
Background technology
At present in timber is used to make furniture processing and installation, it is common to use mild steel countersunk head wood screw, when mild steel countersunk head wood screw is twisted
Tightly on workpiece and after a period of time, due to the contraction of timber and the corrosion of screw, when removing wood screw with screwdriver,
Since the cutter head of screwdriver and a word or cross the fitting position of wood screw tail portion are very easy to loosen and skid, can cause to sink often
A word or crosshead for pollard screw skids or damage so that the taking-up of countersunk head wood screw is extremely difficult.One kind is in Chinese patent
" an a kind of word or Phillips screwdriver " disclosed on document, it is " a kind of in the Publication No. CN204868693U technical solutions
One word or Phillips screwdriver ", including screwdriver ontology, the screwdriver ontology includes lever, LED illumination lamp, screwdriver and spiral shell
Screw, the lever are internally provided with lead screw, and the lead screw is fixedly linked with lever, and control is equipped at the top of the lever and is opened
It closes, the lever is internally provided with accumulator, and described accumulator one end is equipped with contact chip, is set between the contact chip and control switch
Have a drive rod, described drive rod one end is connected with control switch, and the accumulator both sides are equipped with transmission of electricity component, the lever and
LED illumination lamp is equipped between lead screw, the transmission of electricity component is connected with LED illumination lamp, and overall structure is simple, easy to operate, together
Shi Shihe is use the advantages of at night.But should " a kind of a word or Phillips screwdriver " there is to being tightened on workpiece simultaneously
When mild steel countersunk head wood screw after a period of time is removed, it can cause a word of sunk screw or crosshead is skidded and damage so that
The defects of taking-up of countersunk head wood screw is extremely difficult.
Invention content
The mild steel countersunk head wood screw being tightened on workpiece and after a period of time is torn open the present invention specifically addresses existing
Except when, can cause a word of sunk screw or crosshead is skidded and damage so that the taking-up of countersunk head wood screw is extremely difficult to be lacked
It falls into.The word or crosshead that countersunk head wood screw is hardly damaged during a kind of use are intended to provide, can facilitate, reliably dismantle
The mild steel countersunk head wood screw being tightened on workpiece, and the anti-skidding screw wrench that can be used as normal screws knife and take out wood screw
Method.
In order to solve above-mentioned technical problem, the present invention uses following technical proposals：Anti-skidding screw wrench, the knife
The cross section of bar is hexagon, and the cutter head is located at the lower end of knife bar, and the handle of a knife is located at the other end of knife bar, and knife bar is close to knife
Screw rod is equipped at handle, nut is fitted on screw rod and extrusion ring that lower end is taper, is fitted with stop collar on knife bar, on stop collar
If being equipped with open slot horizontally outward there are two symmetrical fixed ear, outside fixed ear, position-limited claw is fitted in open slot, is limited
The lower end of pawl is equipped with tip pawl hooks, and tip pawl hooks are equipped with the upward blade of the edge of a knife, and the top of position-limited claw is equipped with tension spring, hexagon
The knife bar of cross section can cause stop collar that can not only be slided on knife bar, but also will not generate swing offset, pass through adjusting nut
The tip pawl hooks of position-limited claw can be allowd to open or tighten, at work, tip pawl hooks can be inserted into countersunk head wood snail
Below nail head in the timber at inclined-plane position, and the blade of tip pawl hooks can be caused to be embedded in the inclined plane part below wood snail nail head
Position increases screwdriver pressing against power and increase torsion to countersunk head wood screw, effectively prevents driver bit and countersunk head wood
Skidding at one word of screw or cross, the word or crosshead damage, tension spring for avoiding screw can cause position-limited claw to be in always
The state of opening, is conveniently operated, and when rotation screw knife, wood snail is driven together by the blade on cutter head and tip pawl hooks
Nail rotation, can conveniently and effectively dismantle the mild steel countersunk head wood screw being tightened on workpiece and after a period of time, work as limiting
After set and nut and extrusion ring are removed at a word of knife bar or cross cutter head, and can be as the spiral shell used under conventional environment
Silk knife, it is easy to use.
Preferably, the inside of the position-limited claw upper end is equipped with arc surface, the upper end of position-limited claw and the open slot of fixed ear
Place is connected using pin, and accurately position-limited claw can be located in slot, effectively constrains the activity direction of position-limited claw.
Preferably, the angle between the blade is 120 degree so that the inclined-plane kiss below the angle and wood snail nail head
It closes, it is easier to which embedded and active force maximizes.
The present invention also provides it is a kind of using the slip-proof screwdriver take out wood screw method,
Its feature includes the following steps：
A, nut is screwed on screw rod and is packed into extrusion ring；
B, the stop collar equipped with position-limited claw is packed into knife bar and installs tension spring；
C, cutter head is withstood to the cross or flat recess of wood screw；
D, turn nut causes the tip of tip pawl hooks to be aligned in the outer circumferential edge of wood screw tail portion；
E, upper end outside position-limited claw and simultaneously turn nut downwards are tapped with small hammer so that the tip of tip pawl hooks, that is, embedding
In the timber for entering working face, while blade is caused to be embedded in the inclined-plane of wood screw tail portion lower end together；
F, rotation handle of a knife causes knife bar and tip pawl hooks to rotate and take out together with wood screw；
G, countersunk head wood screw is removed after unclamping nut 8.
Due to the adoption of the above technical scheme, the method for anti-skidding screw wrench provided by the invention and taking-up wood screw is beneficial
Effect is：1. it is not easy to skid between driver bit and one word of countersunk head wood screw or cross recess；2. more difficult taking-up can be dismantled
Countersunk head wood screw；3. it is hardly damaged a word or crosshead for wood screw；4. common screwdriver can be used as to use.
