Abstract

The utility model relates to a percussion drill fitting without damage to a wall, can prevent the percussion drill from damaging the surface on the other side of a wall when penetrating the wall, especially from damaging the good appearance of a decorated wall surface. In the utility model, a clip capable of adjusting width is disposed; two ends of the clip are provided with two coaxial guiding circular holes; and by drilling through the coaxial guiding circular holes to make through a wall, a percussion drill bit will cause no unnecessary damage to the wall excepting a circular hole as the same size as the bit.

Description

Do not destroy the Churn drill accessory of metope

Affiliated technical field

The utility model relates to a kind of Churn drill accessory device, particularly a kind of Churn drill accessory device that the opposite side metope is not damaged after punching metope.

Background technology

At present, the Churn drill that uses in the building finishing has only a drill bit, and drill bit penetrates to body of wall inside under the rotation of motor, and the direction of creeping into, angle are controlled grasp by rule of thumb by the finishing personnel fully, tend to offset direction; The position of the 1cm-2cm degree of depth before drill bit penetrates body of wall particularly, the finishing personnel are experience no matter why, adopts the strength of what appropriateness, all can produce the impact to metope, causes metope to break, and forms a 100cm ²About in addition the bigger surface of a wound, bring ugly " scar " for metope fit up, also bring unnecessary repairing to bother to house-owner.

Summary of the invention

In order to overcome the defective that existing Churn drill exists, the utility model provides a kind of Churn drill accessory device, and it can pierce into from the body of wall two sides, forms same passage at last; Perhaps advance from a drill with ferrule, the another side body of wall thereby can not damage metope because strong applying is supported yet.Thereby advance the problem that must damage with regard to having overcome like this to the opposing party's metope from a drill with ferrule.

The technical scheme that is adopted during the invention for solving the technical problem is:

1. the fixedly clip of a similar slide measure is set, there is the guiding circular hole bigger slightly than bit diameter on the top of two mullions of clip, two guiding circular holes are among the coaxial channel, drill hammer creeps into respectively from these two guiding circular hole both sides, form a complete passage at last, get through body of wall; 2. fixedly accompany width adjusting bar and width adjusting knob, screw knob, make geometrical clamp clamp body of wall, guarantee not to be shifted when drill bit creeps into, guarantee the direction unanimity of creeping into; Draw-in groove and block tongue are arranged on the adjusting rod, and the angle of secured adjusted bar guarantees that two guiding circular holes are among the coaxial channel.3. a disk about diameter 12cm is set, is installed in clip wherein on the guiding circular hole of a mullion, the disk metope of tightly fitting, Churn drill advances from another aimming circle hole drill, because keeping out of disk arranged, when Churn drill penetrated body of wall, metope can not form and break.

The beneficial effects of the utility model are:

When Churn drill penetrates body of wall, can not cause metope to break, keep the complete sum of metope attractive in appearance, avoid the trouble of fitting up again.

Description of drawings

Fig. 1 is the geometrical clamp constructional drawing:

1. coaxial guiding circular hole; 2. coaxial guiding circular hole;

3. geometrical clamp width adjusting bar; 4. geometrical clamp width adjusting knob;

5. geometrical clamp adjusting rod draw-in groove and block tongue; 6. metope applying disk;

7. the anti-skidding scratch resistant cushion of metope.

Fig. 2 is the Churn drill working state figure.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

One,

1, geometrical clamp is stuck in the body of wall both sides, 4. the knob that 3. turn geometrical clamp width adjusting bar is gone up regulates width, makes geometrical clamp can tightly clamp body of wall, and 2. 1. the coaxial guiding circular hole in both sides be close to metope;

2, chopping bit aligned coaxial guiding circular hole 2., opening power advances Churn drill, creeps into certain depth;

3, extract Churn drill, 1. chopping bit is aimed at the coaxial guiding circular hole of opposite side, opening power advances Churn drill, up to being communicated with the circular hole of previous brill, gets through body of wall.

Two,

1, it is 2. inboard 6. metope applying disk to be installed in coaxial guiding circular hole;

2, geometrical clamp is stuck in the body of wall both sides, 4. regulates width by geometrical clamp width adjusting knob, make geometrical clamp can tightly clamp body of wall, 6. 1. coaxial circular hole clamp with metope applying disk and touch metope;

3,1., opening power advances Churn drill, up to penetrating the opposite metope chopping bit aligned coaxial circular hole.

Claims

1. Churn drill accessory that does not destroy metope is characterized in that: a geometrical clamp is set clamps metope, geometrical clamp is provided with two coaxial guiding circular holes, and can be installed in the metope applying disk on the side directed circular hole.

2. Churn drill accessory according to claim 1 is characterized in that: fixedly accompany width adjusting bar and width adjusting knob, make geometrical clamp can clamp metope, draw-in groove and block tongue are arranged, in order to the angle of secured adjusted bar on the adjusting rod.

3. Churn drill accessory according to claim 1 is characterized in that: two mullion tops of geometrical clamp are provided with two guiding circular holes that are slightly larger than the chopping bit diameter, and two circular holes are among the coaxial channel.
