Abstract

The invention relates to hand-held clamping devices, can be used to secure, tighten or extend individual elements of the devices, allows for work in hard-to-reach places and reduce the time it takes to reposition the elements of the devices. The clamp includes a housing 1, a power screw 3, a nut 4 with two ratchets 15, 16, handles 5.11, a movable sponge 7, a fixed sponge 8, a guide rib 9, a bracket 10, a connecting fork 12 with stops 13,14 and the lock 20 of the maker fork 12). To move the jaws 7.8, the fork 12 is thrown onto one of the ratchets 15 or 16. With one hand they pull together the handles 5.11. The fork 12 rotates the nut 4 and moves the body 1 with the sponge 7. 6 Il. from sl 77 7 .7 5

Then, depending on whether fragments come together or move apart, throw the platter fork 12 onto the corresponding crown of the nut 4. The fork 12 pivots around the axis 17 and is locked by means of the retainer 20, while one of the stops 13 or 14 rests on the corresponding ratchet crown 16 or 15. After that, the grips of the handles 5 and 11 are compressed with the palm of the hand, causing the handle 5 to overcome the resistance of the spring 19 and move closer to the handle 11, turning

The invention relates to hand tools, and more specifically to hand-held clamping devices, and can be used to secure, shrink or slide apart individual elements of devices.

The aim of the invention is to expand the operational capabilities by ensuring the clamp works in hard-to-reach places of devices and mechanisms and reducing the time for reposition of device fragments.

FIG. 1 shows a clamp, a general view; FIG. 2 is a view B in FIG. one; 15 tachting on axis 6. Handle 5 is given in FIG. 3 is a section A-A in FIG. one; turns on the plug 12, which through the stop in FIG. 4 - a tambouric fork, a common 13 or 14 acts on the corresponding view; FIG. 5 is a view of B in FIG. four; The ratchet crown is 16 or 15 and FIG. 6 - the same, top view. Turns the nut 4, the last one; the clamp contains the body G of the hole-20 moving along the screw 3, pulls together or

Stage 2 $ power screw 3, located in hole 2, nut 4. First handle 5 is fixed on housing 1 rotatably around axis 6. On housing 1 there is fixed movable jaw 7 and at the end of screw 3 fixed jaw 8. The guide rib 9 is located in the opening 2 of the housing 1. The bracket 10 is fixedly mounted on the second handle 11. The connecting fork 12 has stops 13 and 14.

Nut 4 is made with two ratchet crowns 15 and 16, having the opposite gear cutting.

The mat 12 is fastened to the handle 5 on the axis 17, its stops 13 and 14 are located on either side of the axis of the screw 3 with the ability to interact with the ratchet rims 16 and 15, respectively.

Along the axis of the screw 3, a groove 18 is provided, in which the guiding edge 9 of the housing 1 is located. The nut 4 is fixed on the bracket 10 so that it can be retained.

Handles 5 and 11 are made L-shaped, are located in a plane passing through the axis of the screw 3, on both sides of this axis and are spring-loaded relative to each other by means of the spring 19, and the axis of rotation of the handle 5 is perpendicular to the axis of the screw Z. The handle 5 is secured with the locking lever 20 of the telescopic fork 12.

The device works as follows.

The hooks 21 of the jaws 7 and 8 are hooked onto the pins or screws that are screwed into the parts to be fixed or moved.

Then, depending on whether fragments come together or move apart, throw the platter fork 12 onto the corresponding crown of the nut 4. The fork 12 pivots around the axis 17 and is locked by means of the retainer 20, while one of the stops 13 or 14 rests on the corresponding ratchet crown 16 or 15. After that, the grips of the handles 5 and 11 are pressed with the palm of the hand, causing the handle 5 to overcome the resistance of the spring 19 and move closer to the handle 11, turn

; 15 moving on the axis 6. The handle 5 presses the plug 12, which through the stop 13 or 14 acts on the corresponding ratchet crown 16 or 15 and turns the nut 4, finally, moves the jaws 7 and 8. Reverse movement of the jaws 7 and 8 carried out by transferring the mathic fork 12 from one ratchet crown of the nut 4 to the other 25 and post-compression grips of the handles 5 and 11.,

The clamp is convenient in operation, since the toggle of the plug 12 and the compression of the handles. 5 and 11 is carried out by one

30 hand, which ultimately reduces auxiliary time and increases productivity.
