Description

Multipurpose screw driver with manual boosting-rod device

A kind of hand-operated tools that removes and installs mechanical usefulness of technical field.

Background technology is present, and the bottle opener handle diameters that parbuckle screw is used is less, has used power from head to foot although the operator holds handle, and the power that turns that produces is still very little, can't turn rusty screw.In addition, function singleness can only parbuckle screw, not has its and uses.

Occur a kind of multipurpose screw driver in recent years, its lower end is the open type screwed claw, is with the screw threads for fastening sleeve above, and is supporting with it for the cross with specific cards end is started, a word is started, drill bit, reamer head, the first-class series of tools of screw tap.Though this bottle opener function is more, owing to turn the too little cause of power, often unable to do what one wishes, do not reach desired purpose, can not really accomplish multi-functional.

The summary of the invention the purpose of this utility model provides a kind of multipurpose screw driver with manual boosting-rod device, accomplish afterburning moment increase, turn power increase, really realize multi-functional, can parbuckle screw, can hole again, fraising, tapping.

Technical scheme is as follows: change the pattern that existing multipurpose screw driver handle and screwdriver rod are solidified as a whole, screwdriver rod can be rotated in the metal handle seat of the glue system of being equipped with handle, the hole slot top, center of metal handle seat has ball, waist to have location ball, import that ball bearing is arranged, match with the locating slot on screwdriver rod top, make the screwdriver rod upper and lower position fix and can rotate reposefully jointly.Be fixed with ratchet on the screwdriver rod, the ratchet carriage rotation set is on ratchet, and ratchet carriage one side is afterburning seat and hinged manual boosting-rod on it.Time spent not, manually boosting-rod can up rotate and the draw-in groove of the glue system of embedding handle and metal handle seat in.The ratchet carriage opposite side is the ratchet pawl seat, be equipped with in the ratchet pawl seat centre bore by ratchet pawl, outer end the claw bar of commutation handle and the ratchet pawl controlling organization that the compression spring constitutes are arranged, on the commutation handle bayonet lock is arranged, ratchet pawl seat outer face left and right side has the left and right pin-and-hole that inserts usefulness for bayonet lock respectively.

Using method is as follows: put down manual boosting-rod in glue system handle draw-in groove, left hand is held glue system handle, and the right hand is held manual boosting-rod, pulls back and forth to get final product.When the bayonet lock of the handle that will commutate inserts a left side, ratchet pawl seat outer face pin-and-hole, if the counterclockwise manual boosting-rod of switching will force screwdriver rod counterclockwise to rotate by ratchet mechanism.If pull manual boosting-rod clockwise, ratchet carriage will dally along ratchet, and promptly screwdriver rod does not rotate.When the bayonet lock of the handle that will commutate turns over the right side, 180 ° of insertion ratchet pawl seat outer faces pin-and-hole, if pull manual boosting-rod counterclockwise, ratchet carriage idle running, screwdriver rod does not rotate.If pull manual boosting-rod clockwise, screwdriver rod rotates clockwise direction.

Compare with background technology, the utility model has following characteristics:

1, turns the common bottle opener of force rate and increase tens times.

Because the length of manual boosting-rod is 3～10 times of common bottle opener handle diameters, according to lever principle, turn moment and increase more than 6 times, the power that promptly turns increases more than 6 times.

2, can really realize multiple functions such as boring, fraising, tapping.

As everyone knows, the bigger revolving forces of need of work such as boring, fraising, tapping promptly turn power, and the power of turning of utilizing existing multipurpose screw driver to produce does not reach requirement, and adopt the utility model can satisfy the demand fully.The utility model is specially adapted to field work and flight-line maintenance industry.

Fig. 2 is the multipurpose screw driver schematic top plan view with manual boosting-rod device

Fig. 3 is that the A of Fig. 1 is to cutaway view

The specific embodiment is described concrete structure of the present utility model in detail below in conjunction with drawings and Examples.

As shown in the figure, but screwdriver rod 1 lower end has the suit cross to start, one word is started, drill bit, the reamer head, the open-top screw thread pawl of screw tap head and screw threads for fastening sleeve 2, difference is that locating slot 19 is arranged at screwdriver rod 1 top, the middle part is fixed with ratchet 3 and is sleeved on sour jujube sleeve 4 on the ratchet 3, ratchet carriage 4 one sides are afterburning seat 5 and hinged manual boosting-rod 6 on it, opposite side is a ratchet pawl seat 7, ratchet pawl 8 and affixed claw bar 9 are housed in ratchet pawl seat 7 centre bores, be with compression spring 10 on the claw bar 9, claw bar 9 outer ends are fixed with commutation handle 11, on the commutation handle 11 bayonet lock 12 is arranged, a left side, ratchet pawl seat 7 outer face, the right side has respectively and a corresponding left side, bayonet lock 12 positions, right pin-and-hole, glue system handle 13 is sleeved on screwdriver rod 1 top together in company with the metal handle seat 14 that is connected with it, the hole slot top, center of metal handle seat 14 is equipped with ball 15, waist is equipped with location ball 16 symmetrically, import department is equipped with ball bearing 17, and the draw-in

groove

18 and 20 that embeds usefulness for manual boosting-rod 6 is arranged respectively on the same upright position of glue system handle 13 and metal handle seat 14.
