The firmness of the whole device can be improved through the fixing frame and the limiting disc, and unnecessary displacement of the bracket legs during construction is prevented. The spring can help the hole rotating device reset after the hole is punched. And the support legs can be adjusted to be shortest at any time after the operation is finished and then outwards turned over to be embedded into the strip-shaped notch of the sleeve.

Further, the support legs can be respectively and independently adjusted in length in order to cope with the condition that the punching surface is uneven.

Further, the number of the bracket legs is three in order to make the device more firm and reduce the cost.

Further, in order to adapt to different scenes of the vertical wall and the top wall, the outer wall of the sleeve is provided with a bubble window for adjusting the levelness and the verticality of the drill bit.

The beneficial effects of the utility model are as follows: the device has the advantages of low cost, strong adaptability, retraction, work efficiency improvement and accuracy improvement, and further work efficiency improvement.

Detailed Description

In order to enable those skilled in the art to practice the utility model, the present utility model will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1-3, a device for preventing inclination of drilling holes comprises a bracket 1, a fixing frame 2, a sleeve 3 and a spring 4, wherein the bracket 1 comprises bracket legs 11, a limiting disc 12 and a connecting circular ring 13, round holes for allowing drilling tools such as an electric drill to pass through are formed in the middle of the limiting disc 12, the limiting disc 12 is fixedly connected with the connecting circular ring 13, the bracket legs 11 are uniformly connected with the connecting circular ring 13 in a divergent shaft manner, the limiting disc 12 is positioned below the connecting circular ring 13, a groove matched with the bracket legs 11 is formed in the edge position of the limiting disc 12, the bracket legs 11 are fixed and limited to move inwards, the fixing frame 2 is a closed ring consistent with the shape formed by the bracket legs 11, a blocking piece 14 for preventing the fixing frame 2 from moving is arranged near the free ends of the bracket legs 11, two ends of the sleeve 3 are opened, the spring 4 is arranged in the sleeve 3, one end of the sleeve 3 is accommodated in the connecting circular ring 13, the outer diameter of the spring 4 is matched with the connecting circular ring 13, the other end of the sleeve 3 is provided with a strip-shaped embedded sleeve opening 31 matched with the bracket legs 11, and the other end 31 matched with the sleeve legs 11 is provided with a strip-shaped embedded spring 32, and the inner edge 32 of the spring 4 is prevented from falling. The length of the support legs 11 can be independently adjusted, and preferably three support legs 11 can be easily and stably supported. The outer wall of the sleeve 3 is provided with

bubble windows

33 and 34 for adjusting the levelness and the verticality of the drill bit.

When drilling on a vertical plane, the sleeve 3 and the spring 4 are sleeved on a drilling machine to be fixed, then the bracket 1 is placed in the sleeve 3 to be in contact with the spring 4, the free ends of the bracket legs 11 are sleeved on the fixing frame 2 and placed at the position to be drilled, and the bracket legs 11 are adjusted to form a horizontal direction to be drilled by referring to the bubble position in the bubble window 33. After the punching is finished, the pressure on the drilling machine is reduced, so that the drilling machine slowly returns to the original position, and the punching is finished.
