Abstract

The utility model provides a drilling tool pulled by a hand, which is characterized in that a gun-shaped casing is arranged, the casing comprises a gun body with a built-in dynamic mechanism and a holding part for hand hold. The dynamic mechanism is driven by a rope pulled outwards, and one-way rotation power is output to drive a drill bit chuck at the front end of the gun body to cause a drill bit clamped with the drill bit chuck to drill. The drilling tool pulled by a hand is suitable for machining wooden or plastic materials, and the drilling tool pulled by a hand has simple structure, convenient operation and energy saving.

Description

The hand pulling type drilling tool

The utility model relates to a kind of handhold portable churn, particularly a kind of manually driven rig.

Use by present drilling tool is very universal, and the drilling tool kind can be divided into two classes with the power source branch, one is power-actuated electric drill, the pneumatic brill that another drives for air pressure, and the former is because power supply is convenient, use more extensively, but motor when rotation vibration is big, easily causes the drill center skew; Pneumatic brill requires to have source of the gas, must be equipped with air compressor and accumulator, and cost is big, uncomfortable being extensive use of.Drilling tool is except processing on metal material; still can process timber; during converted timber; the too high burned situation of timber that causes of rotating speed takes place in above-mentioned two kinds of drilling tool regular meetings; this type of drilling tool is not to be suitable for timber processing fully; when current social did one's utmost to advocate thriftiness the energy, above-mentioned drilling tool all had weak point.

The purpose of this utility model is that a kind of improved hand pulling type drilling tool will be provided, and it adapts to drilling essence or plastic material, and is easy to use, and saves the energy.

Utility model is achieved in that the hand pulling type drilling tool includes a rifle shape housing, rifle shape housing has the body of a gun and a grip part of a built-in actuating unit, actuating unit driving one is disposed at the drill jig of body of a gun front end, and be one-directional rotation, be characterized in that actuating unit comprises-the coaxial continous action base that is fixedly arranged on drill jig, one with the continous action base arranged coaxial and can drive the dish post of the unidirectional rotation of continous action base, but the gear train of one group of interlock dish post rotation, one can driven gear be the reel that rotates when itself rotates, and one be wound in reel and extend to the rope that body of a gun end exposes, when rope draws outward, can drive reel rotates, then set firmly in the reel when disc spring draws outside rope and can build up torsion, when rope discharges, order about the reel reverse rotation and reclaim rope, dish post periphery is offered an oblique groove, the built-in friction roll of groove, when the dish post clockwise rotates, roller is butted on continous action base, and the dish post is when rotating counterclockwise, roller and continous action base are not contact condition, to drive the continous action base one-directional rotation according to this, form outer the drawing repeatedly of mat rope and drive the hand pulling type drilling tool of the unidirectional rotation of drill chuck.

The utility model is adapted to timber or plastic colloid materials processing, does not have special energy supply requirement, can use at various environment, and applied widely, the energy is saved in manual operation, and simple in structure, easy to use and reliable.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the outline drawing according to the hand pulling type drilling tool that the utility model proposes.

Fig. 2 is the partial sectional view of Fig. 1 structure.

Fig. 3 is Fig. 2 mid-game post, friction roll and groove partial enlarged drawing.

Fig. 4 is an A-A cutaway view among Fig. 2.

Fig. 5 is a B-B cutaway view among Fig. 2.

Fig. 6 is Fig. 5 mid-game post, friction roll, groove and continous action base partial enlarged drawing.

With reference to Fig. 1,2, rifle shape housing 1 is by the hollow body of a gun 10 and supply the grip part 11 of staff gripping to constitute, the body of a gun 10 front ends expose a drill jig 2, and drill jig 2 places the actuating unit driving in the body of a gun 10 and is able to one-directional rotation by one, so that carry out drilling after drill jig 2 clamping drilling bit.The formation of actuating unit is, set firmly continous action base 20 on drill jig 2 is coaxial, continous action base 20 is by dish post 30 unidirectional drive, dish post 30 and driving gear 4 synchronous interlocks, driving gear 4 is that 5 tractions are rotated by rope, rope 5 extends to not end and outer outstanding draw ring 50 of the body of a gun 10, dish post 30 is extended with a driven gear 3 and driving gear 4 engagements, form one and quicken train, establish the reel 40 that twines for rope 5 on the driving gear 4, reel 40 inner hollow also have a pivot 41 as shown in Figure 4, pivot 41 is inserted in the set pivot hole 12 of housing 1, and be center rotation with it, configuration one disc spring 42 in the reel 40, the disc spring two ends are fixedly arranged on the outside of aforementioned reel 40 inboards and pivot hole 12 respectively, drawing outside reel 40 is subjected to rope 5 influences and when rotating, disc spring 42 is reeled and stacking energy, after rope 5 is released, but the energy that reel 40 mat disc springs 42 are built up and reversed turning, to regain rope 5, be beneficial to user's drawing draw ring 50 once more, rope 5 is guided to by fixed pulley 52 and exposes after the body of a gun 10 is not held and be connected in draw ring 50 on its free end.

When rope 5 during repeatedly by drawing, but gear train and dish post 30 continue forward and backward, with reference to Fig. 5 and 6, the outer rim of dish post 30 is established an oblique groove 31, a ccontaining friction roll 32 in the groove 31, and friction roll 32 just can roll in groove 31, when dish post 30 is subjected to the gear train interlock and when clockwise rotating, this friction roll 32 nationality centrifugal force and slide onto the position of the continous action base 20 of can conflicting because groove 31 is tapered configuration, are rotated synchronously and order about continous action base 20; When dish post 30 rotates counterclockwise, friction roll 32 promptly moves to groove flaring part, promptly do not contact with continous action base 20 this moment, shown in Fig. 6 notional line, so that continous action base 20 keeps clockwise rotating, in order to drilling, friction roll 32 is similar to the clutch function herein, and promptly when dish post 30 clockwise rotated, friction roll 32 drove continous action base 20 and rotates synchronously, and when dish post 30 changes counterclockwise, then separate not driving continous action base 20, because the drilling tool drilling is at wooden or plastic colloid material, so only can reach drilling purpose (pull order about when moving coil post 30 clockwise rotate) to pull driving, and the setting of accelerating gear system then is the increase of its kinetic energy of nationality and be beneficial to drilling.
