The spanner wrench (Fig. 1) contains an elongated handle 1, a movable jaw 2, a wrench with a screw 3, slider 4, wither 5.

25 In section 1 (Fig. 2), which has the necessary cylindrical shape, a fixed jaw b is formed. Channel 7 is equipped with a channel 7 for placing a regular part of a movable jaw and channel 8 for using a black screw with a screw. Channels 7 and 8 performed in the next

30 areas are parallel between themselves and communicated due to their intersection.

Channel 8 has a length of up to 9, at a short distance of 10 to accommodate the 11th segment of the four. The distance between the channels 7 and 8 is selected from

35 terms and conditions of purchase 12.

There is a slit 13 (Fig. 3) that is configured in the first place, which is interspersed with a flat surface 14 and interconnected with a channel 7. The lateral walls 15 of the slit are intended for direction \ νθ 96/02359 ΡСΤ / ΚШ4 / 00158

the movement of the movable sponge in the hand. Beyond the disposal of the fixed sponge, channel 16 (Fig. 2), interconnecting with channel 7, is placed in order to accommodate the rising part of the movable sponge.

A simple version of 17 is performed, removing the spiral groove of the rotor screw, which is shared with channel 8 and is intended for the articulation of slider 4 and

10 screw drive. To install the slider, the answer is 18.

At the end of the handles, a cylindrical arrangement for accommodating the hub 19 is provided, in the case of a quick drive 20 for the screw and the shaft 21.

15 To connect V-19 with the manual, two steps 22 and a ring face 23 are completed.

On the movable jaw 2, a cylindrical barrel 24 was arranged for pairing with the channel 7. On the other side, teeth 25 were made for gripping the worm ^' .

On the front screw there is a 31 channel groove for articulation with the slider 4. The 32 slot is located on the 19 shaft with the 33th washer and the 34th wheel.

30 washers 36 have been added, a special hub 37 and a bowl 38. For a slider 4 (Fig. 4) a neck 39 has been opened for an unloading of the slider at a distance of 17. For the overload

Pρi this ensures the installation of the maximum key yaw with a slider to the lower pane 41 of the phase 17. After this, the serum is increased after the pusher is removed.

The keyless yaw of the key is issued as follows. When moving the slider 4 to a distance of 17, it ensures that the rotor 27 and the hinge 26 rotate, and then the teeth 25 that are located on the movable jaw are free of rotation.

The length of phase (17) is calculated for the following formula:

where £. - the length of the groove, - the maximum yaw of the key, η - the pitch of the helical screw,? _\ , - the module of the worm,

Κ - the number of arrivals of the worm, - the diameter of the answer,

(σ is the width of the π phase.

Intended use

The spanner wrench can be used to tighten and unscrew the nuts, screws, flanges, where quick and smooth throat disengagement is required.
