Technical Field
[0001] This utility model relates to a wrench, and more particularly to a novel multi-tooth socket wrench, belonging to the field of wrench technology. Background Technology
[0002] A wrench is a commonly used tool for installation and disassembly. It is a hand tool that uses the lever principle to tighten or loosen bolts, screws, nuts and other threaded fasteners that hold bolts or nuts in open or socketed holes.
[0003] Wrenches are usually made of carbon or alloy structural steel. A socket wrench is a tool specifically used to tighten or loosen bolts and nuts. Its core design includes multiple sockets with hexagonal holes and accessories such as handles and extension rods. It is particularly suitable for operating in narrow or concave positions.
[0004] Traditional socket wrenches often have a toothed post at the end for tightening or loosening that is integrally molded with the wrench. As a result, the toothed post cannot be quickly disassembled or replaced in actual use. They can only be used to disassemble specific bolts, which limits their adaptability and cannot meet a wider range of usage needs. Utility Model Content
[0005] This utility model provides a novel multi-tooth socket wrench to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] This utility model discloses a novel multi-tooth socket wrench, comprising a wrench body, a front end seat fixedly installed at the top of the wrench body, the front end seat adopting a circular structure design, and an inner groove is formed on both the upper surface and the lower back of the front end seat. Each of the two sets of inner grooves has at least four sets of primary fixing holes. An inner wedge is provided inside the upper and lower sets of inner grooves, the thickness of the inner wedge being the same as the depth of the inner groove. At least four sets of secondary fixing holes are formed on the inner wedge. An end tooth plate is fixedly installed at the center of the upper surface of the inner wedge. A hexagonal toothed column is fixedly installed at the center of the upper surface of the upper end tooth plate, and a quadrangular toothed column is fixedly installed at the center of the lower surface of the lower end tooth plate.
[0008] Furthermore, to improve the structural versatility of the two sets of embedded grooves, the groove depths of the upper and lower sets of embedded grooves are the same, and several primary fixing holes are circumferentially distributed at equal intervals through the center points of the embedded grooves.
[0009] Furthermore, in order to improve the hole adaptation effect, both the primary fixing hole and the secondary fixing hole are threaded holes, and the number of the primary fixing hole and the secondary fixing hole are the same and their positions correspond one-to-one.
[0010] Furthermore, in order to fix the inner wedge, the primary fixing hole and the secondary fixing hole are provided with bolts that are adapted to their hole diameters.
[0011] Furthermore, to facilitate the hand-held operation of the socket wrench, a hand-held handle is fixedly installed at the tail end of the wrench body, and the hand-held handle is integrally formed with the wrench body.
[0012] Furthermore, in order to improve the anti-slip effect of the handheld handle, the outer surface of the handheld handle is engraved with several evenly distributed anti-slip patterns.
[0013] Furthermore, in order to prevent the end of the handheld lever from detaching, an anti-detachment seat is fixedly installed at the end of the handheld lever, and the diameter of the anti-detachment seat is larger than the diameter of the handheld lever.
[0014] Compared with the prior art, the present invention provides the following beneficial effects:
[0015] This utility model features hexagonal and quadrangular toothed posts on the front end of a socket wrench. These posts allow for the tightening and loosening of hexagonal or quadrangular bolt grooves, thus achieving the desired hexagonal or quadrangular tightening effect. The hexagonal and quadrangular toothed posts are positioned above and below the front end, respectively, providing a dual-head, multi-tooth effect from both the front and back sides, catering to diverse usage needs.
[0016] Meanwhile, both the hexagonal and quadrangular toothed columns of this utility model are connected to the inner groove of the front end seat through an inner wedge block. In actual use, this allows the toothed column ends to be detachable and replaceable. Multiple sets of toothed columns with different structures can be equipped, so that the toothed columns can be quickly replaced and installed by bolt disassembly and installation. Different toothed column structures can be dynamically replaced according to different usage conditions, thereby meeting the usage needs under different circumstances. At the same time, the installation and disassembly work is convenient. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0024] According to an embodiment of the present invention, a novel multi-tooth socket wrench is provided.
[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a novel multi-tooth socket wrench according to an embodiment of the present utility model includes a wrench body 1. The wrench body 1 has a front end seat 5 fixedly installed at its top. The front end seat 5 has a circular structure design. An inner groove 6 is provided on both the upper and lower back surfaces of the front end seat 5. Each of the two sets of inner grooves 6 has at least four sets of primary fixing holes 7. An inner wedge 8 is provided inside both the upper and lower sets of inner grooves 6. The thickness of the inner wedge 8 is the same as the depth of the inner groove 6. At least four sets of secondary fixing holes 9 are provided on the inner wedge 8. An end tooth plate 10 is fixedly installed at the center of the upper surface of the inner wedge 8. A hexagonal toothed column 11 is fixedly installed at the center of the upper surface of the upper end tooth plate 10, and a quadrangular toothed column 12 is fixedly installed at the center of the lower surface of the lower end tooth plate 10.
[0026] In one embodiment, the upper and lower sets of embedded grooves 6 have the same groove depth, and a number of primary fixing holes 7 are circumferentially distributed at equal intervals through the center point of the embedded groove 6.
[0027] In one embodiment, both the primary fixing hole 7 and the secondary fixing hole 9 are threaded holes, and the number of primary fixing holes 7 and secondary fixing holes 9 are the same and their positions correspond one-to-one.
[0028] In one embodiment, the primary fixing hole 7 and the secondary fixing hole 9 are provided with bolts whose diameters are adapted to their respective diameters.
[0029] In one embodiment, a hand-held lever 2 is fixedly installed at the tail end of the wrench body 1, and the hand-held lever 2 is integrally formed with the wrench body.
[0030] In one embodiment, the outer surface of the handheld lever 2 is engraved with several evenly distributed anti-slip patterns 4.
[0031] In one embodiment, an anti-detachment seat 3 is fixedly installed at the tail end of the handheld lever 2, and the diameter of the anti-detachment seat 3 is larger than the diameter of the handheld lever 2.
[0032] Working principle: This utility model has hexagonal toothed posts 11 and square toothed posts 12 respectively set on the front end seat 5 of the socket wrench. The hexagonal toothed posts 11 and square toothed posts 12 can tighten and loosen hexagonal or square bolt groove structures, thereby satisfying the normal hexagonal or square tightening effect. The hexagonal toothed posts 11 and square toothed posts 12 are respectively set above and below the front end seat 5, so in actual use, they can have the effect of double head and multi-tooth use from the front and back, which can meet different usage needs.
[0033] Meanwhile, both the hexagonal toothed column 11 and the quadrangular toothed column 12 of this utility model are connected to the inner groove 6 of the front end seat 5 through the inner wedge block 8. In actual use, the toothed column end has the practical effect of being detachable and replaceable. When carrying out disassembly and assembly work, multiple sets of toothed columns with different structures can be equipped. In this way, the toothed column can be quickly replaced and installed by bolt disassembly and installation. Different toothed column structures can be dynamically replaced according to different usage conditions, so as to meet the usage needs under different conditions. At the same time, the installation and disassembly work is convenient.
[0034] During installation, simply place the same type of inner wedge 8 into the inner groove 6, then rotate the inner wedge 8 to align the primary fixing hole 7 with the secondary fixing hole 9 one by one, and then install bolts in the primary fixing hole 7 and the secondary fixing hole 9 to fix the inner wedge 8 on the front end seat 5.
[0035] When replacing, simply remove the bolts in the primary fixing hole 7 and the secondary fixing hole 9, then remove the inner wedge 8, and insert the new wedge tooth assembly. It is easy to use and has the practical effect of multi-head use.
[0036] In summary, the technical solution of this utility model solves the technical problem in the background art that "in traditional socket wrenches, the toothed column structure at the end for tightening or loosening is often integrally molded with the wrench, so in actual use, the toothed column of the socket wrench cannot be quickly disassembled or replaced, and it can only be used to disassemble specific bolts, which has certain limitations and cannot meet more usage needs".
