Abstract

The utility model relates to a sheathing structure of a power-driven tool, comprising a power-driven tool which is protruded with a sheathing section and a polygonal driving head, and part of a bead body with elasticity is exposed on one surface of the driving head; a sleeve which is internal provided with a run-through step shape and is divided into an insert hole section, an axle hole section and a sleeve hole section, and the insert hole section and the sleeve hole section are respectively arranged at the two opening ends of the sleeve; the part of at least one steel bead is exposed on the wall surface of the insert hole section, and the axle hole section is provided with a through hole which is at least communicated with the outside of the sleeve; wherein a groove is sunk on the outside of the sheathing section, and the groove surrounds the periphery of the sheathing section and can be clamped by the steel ball exposed on the wall surface of the insert hole section; besides matching the insert hole section to support the sleeve, the sheathing section has clamping function, so as to lead the sheathing of the power-driven tool and the sleeve to have double clamping function, thereby being more stable.

Description

A kind of socket join structure of power drive instrument

Technical field

The utility model relates to the power drive electrician testing tool technology field, particularly a kind of socket join structure of power drive instrument.

Background technology

Known pneumatic tool or electric tool are that polygonal driving head is inserted in the through hole of sleeve, see through the local pearl body that driving head simultaneously exposes, the conflict sleeve lining.There is a little gap in cause between sleeve lining and driving head, and the degree of depth of driving head insertion sleeve is more shallow, so sleeve can play pendulum.

So, the dealer becomes sleeve design the through hole of class's shape, at least divide into embedding hole section, axis hole section and trepanning section, and be provided with the socket section of standing shape in the driving head back, this socket section is inserted embedding hole intersegmental part, add that driving head gos deep in the axis hole section, so, the degree of support of sleeve shaft core position is better, effectively solves the pendulous shortcoming of sleeve.But socket section and embedding hole section are not had a clamping function, and the pearl body of depending merely on driving head comes the clip sleeve, get rid of the tube of press-offing in the operating period of rotating driving head at a high speed easily.

No. 98101447 patent application case in Taiwan " sleeve that the power drive instrument is used " can effectively address the above problem, but the applicant is not content with this, further grinds and creates " a kind of socket join structure of power drive instrument ", improved the working power driven tool.

The utility model content

The purpose of this utility model is to provide a kind of socket join structure of power drive instrument to cooperate the sleeve of aforementioned patent applications case, has effects such as dual clip and stop sleeve concurrently.

For achieving the above object, solution of the present utility model is:

A kind of socket join structure of power drive instrument comprises a power drive instrument, is extruded with a socket section and a polygonal driving head, and this driving head simultaneously exposes the part and possesses flexible pearl body; One sleeve, its inner class's shape for running through is divided into an embedding hole section, an axis hole section and a trepanning section, and embedding hole section and trepanning section lay respectively at two openends of sleeve; The part that embedding hole section wall exposes at least one steel ball, and the axis hole section has the through hole of at least one connection sleeve appearance; Wherein, this socket section appearance is absorbed in a ditch, and this ditch is around around the socket section and the steel ball clip that can be exposed by embedding hole section wall.

The ditch of described socket section appearance not to exceed together, also can be a multiple tracks ditch arranged side by side.Correspondingly, the quantity of annular groove should make steel ball and ditch possess the clip relation on the sleeve.

Adopt said structure, the beneficial effect that the utility model possesses is: the socket section possesses the clip effect simultaneously except cooperating embedding hole section stop sleeve, make the socket of power drive instrument and sleeve, possesses dual clamping function and more firm.

Below in conjunction with accompanying drawing specific embodiment is described further.

The specific embodiment

Shown in Figure 1, power drive instrument 10 and sleeve 20 are toward each other but do not connect together.

Power drive instrument 10 is extruded with socket section 12 and driving head 11 in the face of sleeve 20 1 sides, be absorbed in together around ditch 13 on every side in socket section 12 appearances, and the one side of polygon driving head 11 is exposed local pearl body 14, and this pearl body 14 possesses elasticity and can be pressed in the driving head 11.

Sleeve 20, embedding hole section 22, axis hole section 23, centre bore section 24 and trepanning section 25 are distinguished because of the design of step shape through hole 21 in its axle center; Wherein, embedding hole section 22 and trepanning section 25 are positioned at two openends of sleeve 20 separately, and axis hole section 23 is adjacent between centre bore section 24 and the embedding hole section 22.These sleeve 20 appearances are absorbed in one annular groove 26 and some through holes 28, and these through holes 28 run through barrel and are communicated to axis hole section 23.Hold the annular groove 26 of tightening piece 30 and the barrel between the embedding hole section 22 and run through plurality of holes 27, permission steel ball 31 is inserted corresponding hole 27 and is suppressed by tightening piece 30, must not break away from arbitrarily, causes the part of these steel balls 31 to expose to embedding hole section 22 walls.

Among Fig. 2, power drive instrument 10 connects together each other with sleeve 20.The driving head 11 of power drive instrument 10 passes the embedding hole section 22 of sleeve 20 and enters axis hole section 23, till the pearl body 14 of driving head 11 ejects clip corresponding to through hole 28.This moment, go deep into the socket section 12 of embedding hole section 22, can and strut tightening piece 30 31 extrapolations of the steel ball that exposes, 30 pairs of steel balls 31 of this tightening piece are bestowed reaction force, touch ditch 13 and till ejecting clip up to steel ball 31.

Socket section 12 also possesses clamping function except cooperating embedding hole section 22 stop sleevees 20, allow the socket relation of power drive instrument 10 and sleeve 20, possesses dual clamping function and more firm.

In the present embodiment, power drive instrument 10 is meant a kind of pneumatic tool, but does not get rid of the possibility of electric tool.

Fig. 3 is another embodiment of power drive instrument 10 socket join structures, and its structure is similar with previous embodiment, and the difference place only is: these sleeve 20 appearances are absorbed in twice annular groove 26, and socket section 12 correspondence positions are absorbed in two ditches 13 arranged side by side.Hold tightening piece 30 as for annular groove 26, in groove, be provided with hole 27 structures such as grade of inserting steel ball 31, then identical with previous embodiment, repeat no more.
