The drilling depth of the percussion drill support in the prior art is difficult to control. The inventors have conducted a detailed analysis and found that the above-mentioned technical problems are mainly caused by: the percussion drill support in the prior art does not have a drilling depth measuring tool. Based on the above analysis, the inventors designed a percussion drill holder capable of measuring the depth of a drilled hole.

As shown in fig. 1-3, the utility model discloses an in one embodiment, strike and bore the support and include stay cord 1, measuring component 2, articulated pole setting 3, horizontal pole 4, dead lever 5 and the connecting rod 6 that just constitutes parallelogram frame in proper order, strike and bore 7 and install at the top of pole setting 3, 5 bottoms of dead lever are equipped with fixing base 51, and connecting rod 6 keeps away from 3 one end of pole setting and is connected with 1 one end of stay cord, and the stay cord 1 other end is connected with measuring component 2. The included angle size of long limit and minor face through adjusting the parallelogram frame makes the distance of the minimum of parallelogram frame and peak adjustable at certain extent, through pulling stay cord 1, need not use ladder or scaffold frame, realizes that percussion drill 7 punches towards the ceiling, has avoided the danger that falls that the workman climbed and can meet. The end of the connecting rod 6 is provided with an extension rod 61, and the extension rod 61 is connected with the pull rope 1. Connecting rod 6 is equivalent to the lever, and dead lever 5 is the fulcrum with the pin joint of connecting rod 6, and connecting rod 6 has increased extension bar 61, has lengthened the power arm in other words, and the pulling stay cord 1 is more laborsaving.

Alternatively, the measuring assembly 2 comprises a roller 21, a gauge 22 and a motor 23 for driving the roller 21 to rotate, the motor 23 is fixedly arranged on the fixed seat 51, the pull rope 1 is wound on the roller 21, the gauge 22 is arranged on the motor 23, and the moving distance of the pull rope 1 is measured through the rotation of the roller 21. The roller 21 has an arc-shaped wheel groove, and the pull rope 1 is positioned in the arc-shaped wheel groove. The motor 23 is used for driving the roller 21 to rotate, so that the pull rope 1 is pulled, the pull rope 1 does not need to be pulled manually, and the physical strength of workers is saved; meanwhile, the depth of the drilling hole of the impact drill 7 is measured by measuring the length of the pull rope 1 wound into the roller 21.

Optionally, the fixing rod 5 is an expansion rod, the expansion rod includes a fixing cylinder 52 and a movable rod 53, the lower end of the expansion rod is telescopically sleeved on the upper portion of the fixing cylinder 52, a threaded hole is formed in the upper pipe wall of the fixing cylinder 52, and the fixing cylinder 52 and the movable rod 53 are relatively fixed by screwing a bolt 54 into the threaded hole; the cross rod 4 and the connecting rod 6 are both connected with the movable rod 53, and the fixed cylinder 52 is connected with the fixed seat 51. The top surface of the fixed seat 51 is provided with a balancing weight 55, and the bottom of the fixed seat is covered with a layer of non-slip mat; the weight 55 increases the weight of the fixing base 51, so that the percussion drill support is not easy to topple.
