Description

Spanner lengthener

Technical Field

The utility model relates to an installation and extracting tool technical field, concretely relates to spanner extension ware.

Background

The wrench is a common mounting and dismounting tool, and is a manual tool for screwing bolts, screws, nuts and other threads to tightly hold open or trepanning fasteners of the bolts or nuts by utilizing the lever principle.

In-process of using is dismantled in daily maintenance, because the length of spanner is limited, the staff need use very big power way just can dismantle bolt or nut when dismantling the too dark bolt or the nut that difficult screwing of being difficult for contact or rustting for a long time in the position, wastes time and energy when dismantling, influences work efficiency.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a spanner extension ware, includes articulated box and case lid together, the case lid surface with the bottom half all is provided with a plurality of one-to-one's locating hole, two of them be provided with the pilot pin in the locating hole, case lid one side is provided with two first bolts, the bottom surface of the box be provided with first bolt matched with first screw, the box is kept away from fixed being provided with the sleeve on the side of first screw.

Furthermore, an extension bar is detachably connected in the sleeve.

Furthermore, one end, far away from the box body, of the sleeve is provided with a plurality of second screw holes, one end, close to the box body, of the extension bar is provided with a plurality of third screw holes matched with the second screw holes, and a second bolt penetrates through the second screw holes and the third screw holes to connect the sleeve and the extension bar together.

Further, the box body and the box cover are connected together through hinges.

Furthermore, the sleeve and the extension bar are both provided with anti-skidding sleeves.

Further, the anti-slip sleeve is made of rubber materials.

The utility model discloses the beneficial effect who reaches does:

1. the utility model discloses can be suitable for the spanner of multiple size, application scope is wide, and the fixed spanner that can be firm and the moment of extension spanner have showing and have reduced staff's physical consumption and shortened operation maintenance cycle, are showing and have promoted work efficiency.

2. The utility model discloses be provided with the extension bar, the extension bar can further prolong the moment of spanner, and the dismantlement that makes the spanner can be more smooth is some very tight bolts or nuts.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in fig. 1, a wrench extender includes a case 2, and a case cover 6 connected to the case 2. The lid 6 and the box 2 are connected together by two hinges 8 provided at the edges of the lid 6. The box cover 6 and the bottom of the box body 2 are both provided with a plurality of positioning holes 4, and the box cover 6 and the positioning holes 4 on the box body 2 are in one-to-one correspondence. Case lid 6 is kept away from the one end of hinge 8 is provided with first bolt 5, the quantity of first bolt 5 is 2, first bolt 5 is located the both sides of case lid 6, 2 bottoms of box are provided with the first screw 3 that first bolt 5 corresponds, first bolt 5 with first screw 3 can fix spanner 1 together through threaded connection and not take place the displacement in vertical direction. Positioning bolts 7 are arranged in the two positioning holes 4 adjacent to each other on the left and right of the wrench 1, and the positioning bolts 7 can fix the wrench 1 to be not moved in the horizontal direction. Fixedly connected with sleeve 9 is kept away from on the side of first screw 3 to box 2, be provided with extension bar 13 in the sleeve 9, sleeve 9 is kept away from the one end of box 2 is provided with a plurality of second screw 10, extension bar 13 is close to the one end of box 2 be provided with a plurality of with second screw 10 matched with third screw 12, second bolt 11 passes second screw 10 with third screw 12 will sleeve 9 with extension bar 13 is connected to together. The length of the torque of the wrench 1 is further controlled by inserting the second bolt 11 into the different second and third threaded holes 10, 12.

The utility model discloses when using, the staff is opened case lid 6 will the one end of spanner 1 is put into in the box 2, closed case lid 6 is screwed up 6 marginal first bolt 5, will first bolt 5 with 3 threaded connection of first screw together make the vertical direction of spanner 1 can not take place the displacement, will again the pilot bolt 7 inserts case lid 6 with on the box 2 in the locating hole 4, make the pilot bolt 7 closely paste and lean on spanner 1's both sides are fixed spanner 1 does not take place horizontal displacement, at this moment, spanner 1 is firm to be fixed in the box 2, the staff can hand sleeve 9 carries out the work of dismantling the bolt. If the bolt is deep or greater strength is required for disassembling the bolt, a worker can insert the extension bar 13 into the sleeve 9, and then the second bolt 11 sequentially penetrates through the second screw hole 10 and the third screw hole 12 to fix the extension bar 13 in the sleeve 9. At this moment, the moment of spanner 1 further lengthens, and according to lever principle can know that the staff can more easily dismantle the bolt.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
