Description

The invention relates to mechanical engineering, namely hand tools, and can be used in single-handle tool kits.

Known hand tools, comprising a housing, covering its retainer in the form of a clip, a working body with a shank accommodated in the housing, and pins 1.

However, the known tool does not allow for the application of longitudinal forces, since the pin of the lock takes up the entire load and, when used as a working member of the hammer, this pin is cut off.

Closest to the invention is a hand tool comprising a body with a bayonet groove made in E) of an ideal part, a lock with longitudinal grooves, a working body with a shank, spaced in the body and made with a cross-shaped protrusions, and connecting pins 2 .

. The disadvantage of this tool is the low reliability of fastening the working body due to the possibility of jamming the shank of the working body in the housing.

The purpose of the invention is to increase the reliability of fastening the working body.

This goal is achieved by the fact that a hand tool comprising a housing with bayonet grooves, a latch with longitudinal grooves, a working body with a shank, one in the housing and made with wheel-shaped protrusions, and connecting pins, is provided with a casing and a leash, the housing is made of two parts covered by the casing and connected to it by a thread, a retainer is placed between the parts of the body, a leash is mounted on the casing with the possibility of moving along it and connected by means of a pin to the retainer, the free end of the shank is formed with a longitudinal pazo.m accommodating the pin connecting the leash with a clamp, and the pin connecting the tang to lock the housing and one part is arranged in bayonet grooves and longitudinal.

FIG. 1 shows a hand tool, a general view, a section; in fig. 2 - upper part of the body, section; in fig. 3 - lower part of the body, section; in fig. 4 - casing, incision; in fig. 5 - lock, cut; in fig. 6 - lead, cut; in fig. 7 - the shank of the working body.

The hand tool comprises a body made of two parts 1 and 2, covered by a casing 3 and connected to it by means of a thread, a working body (not shown) with a shank 4 disposed in the body, connecting pins 5 and 6, a leash 7, mounted on the casing 3 with the possibility of movement along it, the latch 8 placed between the parts I and 2 of the housing. The leash 7 is made with an annular groove 9 and with diametrically opposite longitudinal grooves 10. In the retainer 8 there are diametrically opposite pro-holes 12.

longitudinal grooves

Part 1 of the body is made with boom.m 13, longitudinal groove 14 and hole m 15. The housing part 2 is made with bayonet slots 16 and hole m 17. 17. Diametrically opposite grooves 18 are made in the wall of case 3. In shank 4 a longitudinal groove 19, a hole 20 for pressing in the pin 6 and an emphasis 21 are made. A pin O connecting IHJBO 7 to the latch 8 is sized in the annular

the driver's groove 9, longitudinal grooves 18 of the casing 3, holes 12 of the retainer 8, and longitudinal grooves 14 and 19 of the body part 1 and the shank 4, respectively. The pin 6 connecting the shank 4 to the latch 8 and part 2 of the body is located in the bayonet slots

16 housing, the longitudinal grooves 11 of the latch 8 and the hole 20 of the shank 4, the ends of the pin 6 form a cross-shaped projections on the shank 4 of the working body.

The assembly of the hand tool is carried out in the following manner.

Part I of the housing is fastened to (3, then between spring 1 and the casing 3 a spring 22 and a clamp 8 are placed so that the axis of the openings 12 of the clamp 8

coincided with the axle of the section; ip and l of the slots 14 and 18 of the housing part 1 and the housing 3 are appropriate, after which they insert 1pt 5.

when the ends of the pin 6 are at the beginning of the curvilinear section of the bayonet groove 16, the pin rests on the lower end of the retainer 8, and the upper end of the shank 4 rests on the pin 5. When you turn the shank 4, the retainer 8 piptens and shrinks the 11p-jaw 22 . The rotation of the shank 4 is carried out until the stop 21 contacts with the end face of the part 2 Kopnvc.

At this moment, the longitudinal groove 19 of the tailpiece is installed along PGPKRT 5, the pin 6 is set under the longitudinal axis: the grooves 11 of the clamp 8. Under the action.-, i of the retainer 22 the clamp 8 along with the driver (: goes down, while the pin is about ;

The tool is ready for docking with another working body. The offered hand tool provides high reliability of fixing the working body and has high strength.
