Q: What is the structure of the hammer is: The rotary drill is driven by an electric motor through a gear to drive a pair of straight bevel gears, so that the cylinder sleeve rotates with the six square sleeve through an overload protection device and transmits torque to the drill rod. Thus, the composite motion of the impact belt is formed simultaneously with the impact mechanism. The impact is the main, the rotation is secondary, and the hammer is turned again, so that the construction drill is pushed forward and gradually becomes the required circular hole.Spring, steel ball, bowl washer etc. the overload protection device. When the torque exceeds a certain range (16ram, 18mm hammer is 15 ~ 25N - m, 22mm, 24mm hammer is 20 ~ 35N - M), torque rotating sleeve, press the steel ball through its six semicircular concave hole, the radial ball pops up, the bowl washer compression spring to a certain distance, to set the and the cylinder liner disengaged. At this moment, although the motor is rotating, the drill rod has not turned. In this way, the utility model can provide protection for the hard and soft of the concrete, the uneven or uneven use of the drill pipe, the jamming of the drill rod, the wrench of the operator's wrist and the burning of the motor, etc..

Q: What is the electric hammer, electric drill, difference: Drill (also known as pistol drill) is mainly used for metal, plastic, wood and other materials on the drilling, reaming, if matched with a special head, also can complete the grinding, polishing, and dismounting screws, open metal hole, stirring etc.. Electric broker is a hand-held electric tool, he has the advantages of small volume, light weight, convenient carrying, reasonable structure, safe and reliable use, widely used in machine assembly, motor vehicles, buildings, bridges, wood processing and other metal and non-metal parts of drilling, for switch and limit power parts processing factory the workpiece can not use the drilling machine case, drill up often handy,

Q: How to maintain the hammer?: Dust caps should be replaced regularly. When changing carbon brush, the best mechanical part of the hammer for maintenance,Replace the lube oil and the main O ring.The outlet should be kept unblocked. In the use of the process, do not add a lot of force, drilling deep holes need to be completed several times

Q: Not hammer knob can be changed you: First of all you have to understand the positive adjustment knob is mechanical adjustment button, the switch knob two function is in hammer and hammer drilling function. You said this idle statement is wrong, you said that is the case in the hammer hammer function under the condition.

Q: Turn around the hole hammer reinforced anti torque more vigorously: Although the hammer high speed about 400 rpm, but the reaction is relatively large, if the wall stuck thread steel, do not let go of serious hand off.

Q: How much is the normal value of insulation resistance of electric hammer: Insulation resistance is measured by an insulated resistance meter, usually with 1 or 0.5 orders of accuracy, which is the most common. When measuring with chuck head. Another pathway, chuck clamp wire, rotate the handle by hand, turn to 60 per minute to 100 RPM speed, see pointer where the read value is the measured value of insulation resistance.

Q: Why is the electric hammer drill chuck and loose: Hammer principle is the driving mechanism to make rotation movement while the driven drill, hammer and reciprocating in a direction perpendicular to the rotor hammer motion. The hammer is driven by the transmission mechanism of reciprocating piston in a cylinder of compressed air, the air pressure change cycle reciprocating hammer drives the cylinder top blow brick in the cylinder, if we use a hammer percussion hammer named brick.

Q: The hole hammer in tiles, tiles will be split?: Glass drilling on the tile, the first inclined direction hit a pit; otherwise smooth tile is too bad; or not all tiles, with nails directly make a little hole; it is accurate, can also use a hole (size) has the best set of plates.

Q: The hole hammer in tiles, tiles will be split?: With a shallow mark, you can remove the hole plate, and then. Prepare a water bottle in advance, drill a hole in the bottle cap, and fill the bottle with water. Then, when drilling, at the same time to water into the drill bit and ceramic tile contact parts; especially all ceramic tile, must have water oh.
