Description

Technical Field

[0001] The utility model belongs to the technical field of hardware tools, and particularly relates to an adjustable scale spanner. Background Art

[0002] According to the prior art, a patent with application number CN201620729408.7 discloses a multifunctional ratchet extension wrench, comprising a handle body and a head respectively connected to the two ends of the handle body, the handle body and the head are an integrally formed structure, the handle body comprises an upper end face and a lower end face, a smooth plane structure is formed between the lower end face and the head, and a scale of length unit is engraved on the edge of the upper end face.

[0003] The patent increases the functionality of the wrench by engraving length scales on the handle, making it more practical, and increasing the length of the handle to make it more labor-saving when used. However, the increase in the length of the handle also increases the space occupied by the wrench, making it difficult to carry and store the wrench. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and to provide an adjustable scale spanner with adjustable length and more flexibility and versatility.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an adjustable scale wrench, comprising a first handle body and a second handle body, wherein a head is formed at one end of the first handle body and a sliding groove is provided at the other end, wherein the sliding groove has three side walls formed on the first handle body, and a continuous sliding guide rail is formed on the protrusions on the side walls, and an outer scale is provided on both sides of the sliding groove on the upper end surface of the first handle body;

[0006] A head is also formed at one end of the second handle body, and a guide rail groove cooperating with the sliding guide rail is opened on three sides of the other end. The second handle body is inserted into the sliding groove along the sliding guide rail from the open side of the sliding groove to slide with the first handle body. The second handle body is provided with inner scales on both sides of the upper end surface. After the length position of the second handle body is adjusted in the sliding groove of the first handle body, the first handle body and the second handle body are relatively locked and fixed by the locking screws on both sides.

[0007] In the above-mentioned adjustable scale wrench, the ratchet ring of the first handle body head has a diameter greater than that of the ratchet ring of the second handle body head.

[0008] In the above-mentioned adjustable scale wrench, the first handle body is provided with screw holes on both sides of the end of the sliding groove, and the sliding guide rail is provided with screw grooves corresponding to the screw holes on both sides. The locking screw passes through the screw hole and the screw groove and is inserted into the guide rail groove of the second handle body to lock and fix it.

[0009] In the above-mentioned adjustable scale wrench, when the combined length of the first handle body and the second handle body is the shortest, the scales at the head and tail of the outer scale correspond to the scales at the head and tail of the inner scale respectively; when the combined length of the first handle body and the second handle body is the longest, the scales at the tail end of the outer scale correspond to the scales at the tail end of the inner scale.

[0010] Compared with the prior art, the utility model provides an adjustable scale wrench, which can adjust the corresponding wrench length according to the required torque through relative sliding adjustment between the first handle body and the second handle body, and is flexible, versatile and more practical. By setting scales on both sides of the upper end surfaces of the first handle body and the second handle body, the wrench can adapt to scale readings when used in different directions, and at the same time, the inner and outer scales can be superimposed for measurement, which can adapt to measurement needs in different usage environments.

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figures 1 to 3 As shown, the adjustable scale spanner includes a first handle body 100 and a second handle body 200. A head is formed at one end of the first handle body 100, and a sliding groove 110 is provided at the other end. A head is also formed at one end of the second handle body 200, and the other end is fitted in the sliding groove 110. Ratchet rings are installed at the heads of the first handle body 100 and the second handle body 200. The diameter of the ratchet ring at the head of the first handle body 100 should be larger than the diameter of the ratchet ring at the head of the second handle body 200, so that the spanner can be used in both directions and is suitable for fasteners such as bolts and screws of different specifications and sizes.

[0017] like Figure 3As shown, three side walls are formed in the sliding groove 110 of the first handle body 100, and a continuous sliding guide rail 111 is protruded on the side wall. The end of the second handle body 200 that cooperates with the sliding groove 110 is provided with guide rail grooves 210 that cooperate with the sliding guide rail 111 on three side surfaces. When the two are assembled, the second handle body 200 is inserted into the sliding groove 110 along the sliding guide rail 111 from the open side of the sliding groove 110, so that the overall length of the wrench can be adjusted by relative sliding adjustment between the first handle body 100 and the second handle body 200.

[0018] The first handle 100 is provided with screw holes 112 on both sides of the end of the sliding groove 110, and the sliding guide rail 111 is provided with screw grooves 113 corresponding to the screw holes 112 on both sides. After the second handle 200 is adjusted in length and position in the sliding groove 110 of the first handle 100, the locking screws 130 on both sides pass through the screw holes 112 and the screw grooves 113 from the outside to the inside, and then are inserted into the guide groove 210 of the second handle 200 to be locked and fixed. The locking screws 130 on both sides between the first handle 100 and the second handle 200 can adjust the corresponding wrench length according to the required torque, making the wrench flexible and versatile, and more practical.

[0019] The upper end surface of the first handle body 100 is provided with outer scales 120 on both sides of the sliding groove 110, and the upper end surface of the second handle body 200 is provided with inner scales 220 on both sides. Figure 1 As shown, when the combined length of the first handle body 100 and the second handle body 200 is the shortest, the scales at the head and tail of the outer scale 120 correspond to the scales at the head and tail of the inner scale 220. Figure 2 As shown, when the combined length of the first handle body 100 and the second handle body 200 is the longest, the tail end scale of the outer scale 120 corresponds to the tail end scale of the inner scale 220 .

[0020] The inner scale 220 and the outer scale 120 are both provided on both sides of the handle body, so that when the wrench needs to be used in both directions and needs to be changed in direction, the user can still read the scales conveniently. Since the inner scale 220 and the outer scale 120 correspond to each other, the inner scale 220 and the outer scale 120 can be superimposed for measurement, so as to meet the measurement needs in different use environments.

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
