 iibie in the annular groove 7 of the anvil 5, interact with the beveled ends 15 of the strikers 12 and periodically lift the strikers 12, compressing the springs 13. Under the influence of the springs 13, the strikers 12 hit the anvil with their butt HA to change the number of beats per spindle revolution. It is suitable for building I and is intended to carry out no drilling work.

 The aim of the invention is to expand the technological capabilities of the drilling machine by adjusting the number of strokes per spin rotation;

The drawing shows schematically jg l, it is necessary with the help of the corresponding proposed drilling machine. non-working polishing machine (|) ixators 17; the machine includes a housing 1, in which the spindle 2 is brought out of the required rum; a spindle 2 is connected, the connected number of the impactor pairs 12 from the interaction key 3 with the drive shaft 4, and for this 5, the torsors 17 are rigidly mounted on the cone-) 5 tori are screwed into the body of the 1st part 6 of the spindle 2. In the upper part of the anvil 5 there is an annular groove 7 with radial pins 8. Radial pins 8 are placed in

In order to remove the required number of pairs of impactors 12 from the interaction with the pins 8, forcing (17) rotators 17 in the non-working position of the strikers. For this purpose, the locking devices 17 are screwed into the housing 1.

the result of the interaction of the spherical head 18 of the clamps 17 with the conical section 16 of the corresponding drummers 12 is their conclusion from the interactions

In case 1 there are at least one and a pair of longitudinal holes 11 located symmetrically relative to the axis of the case and containing-- 12 with springs 13. 25 Drummers 12 are in contact with alloys with 5 butt end 14, and with radial pins 8 with end 15, which is made with a bevel. On each of the drums: 12 you Formula A hand drill is machining the body with the spindle located and at least spring-loaded shockers longitudinally from the body and intended The conical section 16 is full. which has 30 actions with radial pins and is designed to interact with the corresponding latch 17 of the inactive position of the impactors. Each latch 17 is fixed in the housing .1 with the possibility of radial movement 35 I and made with a spherical head | 18. mounted on the anvil, about t l. and in order to expand technological capabilities by adjusting the number of impacts, the ends of the strikers facing the pins are bevelled, and at the opposite end of each impactor there is a conical section with a smaller base in the direction of the anvil, designed to interact with the corresponding of the fixed position of the inactive position of the impactors inserted into the device and radially located in the machine body. f drilling machine work-. the following way.d ,, i When turning on the drive (not shown): the rotation of the shaft 4 is transmitted through the key 3 to the spindle 2 with the anvil 5. The radial pins 8 are placed with the pins 8. o Invention Formula A handheld drilling machine, containing a body with a spindle located in it and at least one pair of spring-loaded impactors installed in the longitudinal holes of the body and intended for dp interaction with radial pins, is mounted on the anvil, about t l. and in order to expand technological capabilities by adjusting the number of impacts, the ends of the strikers facing the pins are bevelled, and at the opposite end of each impactor there is a conical section with a smaller base in the direction of the anvil, designed to interact with the corresponding of the fixed position of the inactive position of the impactors inserted into the device and radially located in the machine body.
