Abstract

The utility model provides a combination multi-use drill champ key, different types of keys are made by the way of combination at different positions of a ring, the corresponding key type is labeled at corresponding position of the ring surface. The utility model has the following advantages that: the volume is larger than that of a single key, as a special tool, the key is easy to be found and is not easy to lose or wastes time to find; hand feeling is good when handing with the structure of the ring, rotation twisting motion saves effort so as not to cut into the flesh of hands due to submitting ring for cross bar; many keys are combined and are also labeled the types respectively, the key is easy to accurately select the key when using, and saves time to select the type, a plurality of electric drills only need to use a combination-key in common with convenient; being suitable for a plurality of drill champs.

Description

Multifunctional combined drill jig key

Technical field

The utility model relates to a kind of instrument that loads and unloads drill bit, especially a kind of multifunctional combined drill jig key.

Background technology

At present, tighten the clamping drill bit or unclamp instrument (being commonly called as key) general configuration such as the Fig. 2 or shown in Figure 3 that pulls down drill bit as drill jig (electric hand drill or bench drill).Mainly utilize its conical surface gear teeth to cooperate with the gear teeth 6 on the drill jig 5, just or the despining twisting can unclamp or clamp drill bit 7 (Fig. 4), in use its weak point is mainly:

1. for making things convenient for hand can make energetically, the cross bar 4 that key provides is general short or little, use very hard, rein in hand.

2. the volume of key is little, often loses or is difficult in the use and find, and loses time, and many workmans just impact to unclamp or to clamp drill bit 7 with hammer facing to the gear teeth on the drill jig with screwdriver, damage drill jig easily.

3. the gear teeth model of drill jig is various at present, under more than one situation of electric drill (bench drill), often for selecting for use key to lose time.

Summary of the invention

The purpose of this utility model provides and a kind ofly with many key of different model combination is produced on together, is difficult for losing, and is easy to use, the multifunctional combined drill jig key in rotation twisting labour-saving.

Technical solution adopted in the utility model is:

The key combination of multiple different model is produced on the diverse location on the annulus, the corresponding key model of mark on the anchor ring of relevant position.

The utility model has the advantages that:

1. more single key of its volume is big, finds easily as specific purpose tool, is difficult for losing or looks for losing time.

2. circulus hold by the time good hand touch, it is laborsaving to replace cross bar rotation twisting with annulus, does not rein in hand.

3. many combinations mark model again respectively, use key during use easily with sitting in the right seat, select model to save time, and many handles (platform) electric drill only needs a shared pair key combined, conveniently saves trouble.Be fit to a plurality of drill jigs.

The specific embodiment

With multiple (two or more) or manyly the key 1 of different model is made combination respectively be fixed on the annulus 2, promptly the outer end fixedly the shank of the key of key be connected on the circumferential periphery diverse location of annulus 2, each key is preferably equidistant to be fixed.The model 3 of this key on the mark of corresponding key 1 position on 2 of annulus.Annulus is promptly as the connector of key, again the moment handle when moving as knob.

Claims

1. a multifunctional combined drill jig key comprises the drill jig key, it is characterized in that: the key of multiple different model (1) combination is produced on the diverse location on the annulus (2), mark corresponding key model (3) on the annulus of relevant position (2) face.
