[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a railway patrol wrench comprises a handle, a connecting piece is correspondingly arranged inside the handle, a wrench body is arranged at the other end of the connecting piece, a fixed wrench head is fixedly connected to one end of the wrench body, a movable wrench head is correspondingly arranged at the other end of the wrench body, and sliding grooves are provided at both ends of the connecting piece;

[0006] Slide blocks are fixedly connected to the inner ends of the handle, and the slide blocks are slidably connected to the inside of the slide slot. The inside of the slide slot is provided with a plurality of first screw holes, and the two ends of the handle are threadedly connected to second positioning bolts, and the second positioning bolts correspond to the first screw holes.

[0007] As a further description of the above technical solution: an adjusting nut is arranged inside the wrench body, and an adjusting screw is matched with the adjusting nut.

[0008] As a further description of the above technical solution: an anti-slip sleeve is provided on the outer side of the handle.

[0009] As a further description of the above technical solution: a limiting groove is provided on the connecting piece, and one end of the wrench body is fixedly connected to a limiting block.

[0010] As a further description of the above technical solution: a second screw hole is opened inside the limiting groove, and a first positioning bolt is threadedly connected to the limiting block, and the first positioning bolt corresponds to the second screw hole.

[0011] As a further description of the above technical solution: positioning grooves are provided at both ends of the limit groove, a connecting groove is provided inside the limit block, a spring is fixedly connected inside the connecting groove, the other end of the spring is fixedly connected to the limit plate, the other end of the limit plate is fixedly connected to the positioning block, and the positioning block corresponds to the positioning groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, the railway patrol wrench can improve the anti-slip performance of the entire wrench by arranging an anti-slip sleeve on the outer side of the handle, prevent the wrench from slipping out of the hand during use, and improve its use effect. At the same time, the slide groove, the slider, the first screw hole and the second positioning bolt are arranged to adjust the length of the entire wrench. By extending the length of the wrench, the user's strength to twist the nut or screw on the patrol track is reduced, which effectively avoids the user using a large force to twist the wrench, causing arm pain, affecting the user's subsequent maintenance work, and further effectively improves the practicality of the device;

[0014] 2. Compared with the prior art, the railway patrol wrench can realize the disassembly and replacement of the wrench body by setting the limit block, the limit groove, the positioning block and the positioning groove, thereby improving the convenience and practicality of the entire wrench when in use.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-4 The utility model provides an embodiment of a railway patrol wrench, comprising a handle 5, a connecting piece 7 is correspondingly arranged inside the handle 5, a wrench body 21 is arranged at the other end of the connecting piece 7, one end of the wrench body 21 is fixedly connected with a fixed spanner head 9, and the other end of the wrench body 21 is correspondingly arranged with an active spanner head 1, and sliding grooves 10 are provided at both ends of the connecting piece 7, and the disassembly and installation of the railway patrol bolts can be realized through the cooperation between the active spanner head 1 and the fixed spanner head 9;

[0025] Slide blocks 12 are fixedly connected to both ends of the inner side of the handle 5. The slide blocks 12 are slidably connected to the inside of the slide groove 10. The inside of the slide groove 10 is provided with a plurality of first screw holes 11. Under the action of the slide blocks 12 and the slide groove 10, the connecting member 7 can slide inside the handle 5, so that the length of the wrench body 21 can be adjusted.

[0026] The two ends of the handle 5 are threadedly connected with the second positioning bolts 13, and the second positioning bolts 13 correspond to the first screw hole 11. The interior of the wrench body 21 is provided with an adjusting nut 3, and the adjusting nut 3 is matched with the adjusting screw 2. The second positioning bolts 13 at both ends are screwed to make the second positioning bolts 13 leave the interior of the first screw hole 11. At this time, the staff pulls the connecting member 7 outward to adjust the length of the wrench body 21. After the adjustment is completed, the second positioning bolt 13 is screwed inward to make it match with the first screw hole 11 to achieve its locking and fixing function, thereby ensuring the stability after adjustment;

[0027] The outside of the handle 5 is provided with an anti-slip cover 6, which can increase the contact area with the palm of the user, thereby improving its anti-slip performance;

[0028] A limiting groove 14 is provided on the connecting piece 7, one end of the wrench body 21 is fixedly connected to the limiting block 8, a second screw hole 17 is provided inside the limiting groove 14, a first positioning bolt 4 is threadedly connected to the limiting block 8, the first positioning bolt 4 corresponds to the second screw hole 17, positioning grooves 15 are provided at both ends of the limiting groove 14, a connecting groove 18 is provided inside the limiting block 8, a spring 19 is fixedly connected inside the connecting groove 18, the other end of the spring 19 is fixedly connected to the limiting plate 20, and the other end of the limiting plate 20 is fixedly connected to the positioning block 16, the positioning block 16 corresponds to the positioning groove 15, when the spanner head is damaged during use, the first positioning bolt 4 is screwed to make it leave the inside of the second screw hole 17, and then the positioning blocks 16 at both ends are pressed inwardly. Under the action of the spring 19, the positioning blocks 16 can be retracted inwardly, thereby leaving the inside of the positioning groove 15, and then the staff can pull the limiting block 8 outward to disassemble and replace the entire spanner head, thereby improving the practicality and convenience of the entire spanner body 21.
