Abstract

A foldable and adjustable socket wrench is especially suitable for the construction site of electric power transmission lines, railways and other traffic departments. The handle is movably connected with the plate body and can rotate along the plate body. When the fastener on the electric power iron tower is to be pulled and screwed, if the wrench space is too small and the wrench cannot be placed, the torque of the small wrench is insufficient, the wrench can be used for firstly rotating the handle upwards by 90 degrees and then rotating the handle through the pawl, the ratchet wheel realizes the forward and reverse rotation of the sleeve, and the fastener is pulled and screwed. The sleeve can be disassembled and replaced according to the size requirement of the fastener, so that the application range of the wrench is expanded, and the requirements of different construction units are met.

Description

Can roll over, adjustable socket wrench

The utility model relates to a kind of hand-operated tools spanner, and use the job site of traffic departments such as suitable especially electric power transmission line, railway rolls over, adjustable socket wrench.

For increasing work efficiency, satisfy different operating place needs, the patent of multi-functional or special spanner easy to use is arisen at the historic moment, and has their own characteristics each.

The patent No. 93215244.9 " spanner " just provides a kind of box spanner with ratchet, can't bear big torsional moment though can change the ratchet direction.

It is a kind of easy to use that the purpose of this utility model is to provide, and the scope of application is extensive, practical rolls over, adjustable socket wrench.

The utility model be achieved in that can roll over, adjustable socket wrench is made up of the plate body that has sleeve, ratchet, ratchet, support column and handle, and handle and plate body flexibly connect, and can rotate along plate body.

Fig. 1. be structural representation of the present utility model.

Fig. 2. be the vertical view of Fig. 1.

Fig. 3. be the A-A view of Fig. 2.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Upper and lower cover plate (3), (7) are an end circle, square plate-like of an end.

Handle (8) one ends are cylindrical, and there is through hole other end on being, Yi Bian be the right angle, Yi Bian be the grip block of circular arc.

Sleeve (1) has three grooves and an annular groove of five equilibrium for there is the cylindrical shape that hexagonal through hole upper end is little, the lower end is big the centre on the periphery wall.

Ratchet (4) is circular, and there is hook tooth the neighboring, has three grooves of five equilibrium and three grooves on the sleeve (1) to be complementary on the internal perisporium.

Have on arc opening groove, the two side in the middle of matrix (6) one ends through hole is arranged, end is by through hole and the fixing support column of being made up of spring etc. (5) in addition.

Lower cover (7) is enclosed within on the sleeve (1), and ratchet (4) utilizes the groove on it to link into an integrated entity by 3 flat keys (10) and sleeve (1).Cover upper cover plate (3) and upper and lower cover plate (3), (7) and matrix (6) are fused, constitute plate body with rivet.Ratchet (9) is fixed between upper and lower cover plate (3), (7) with rivet, and contacts with support column (5).Dispose into collar (2) fixingly at the annular groove of sleeve (1), the grip block of handle (8) one ends inserts in the open slot of matrix (6) and connects into integral body with rivet, and can only along matrix (6) upwards a direction rotate 90 °.

When using this spanner to pull nut on the electric power tower, if the spanner usage space is too little, spanner is put to be advanced can not spin nut the time, handle (8) upwards can be rotated 90 ° and arrive upright position as shown, turning handle (8) again, need not change sleeve (1) position, the forward and backward that drives ratchet (4) realization sleeve (1) by ratchet (9) just can be tightened the nut of required turn.Just can change turning to of ratchet (4) as long as stir ratchet (9).

At this moment the nut or the securing member of other different size if need tighten or outward winding only need collar (2) is disassembled, and change the sleeve of required size, put collar (2) again and can use again.

The utility model is compared with prior art: so the handle capable of being of spanner rotates, and just can solve because of spanner Usage space is too little, and the securing member of required turn is big, and too little wrench torque is too little can't turn Drawback, therefore practical. Sleeve can be dismantled in addition, changes into the cover of needed various different sizes Tube is as long as forward and reverse rotation handle promotes ratchet by ratchet and rotates, thereby finishes different sizes tight Tightening or revolving pine of firmware, easy to use, enlarged again the scope of application simultaneously.

Claims
