Description

Technical Field

[0001] This utility model relates to the field of hand tool technology, specifically a retractable multi-purpose wrench. Background Technology

[0002] A wrench is a commonly used tool for installation and disassembly. It is a hand tool that uses leverage to tighten or loosen bolts, screws, nuts, and other threaded fasteners that hold bolts or nuts in open or recessed holes.

[0003] Chinese Patent No. CN219987448U discloses a wrench including a handle, a drive unit, and a stop plate. The handle extends in a first direction, and the drive unit is located at the end of the handle in its extending direction, having an opening. The stop plate is rotatably disposed on the drive unit or the handle and has a stop position and a disengagement position. When the stop plate is in the stop position, a portion of the stop plate is opposite to a portion of the opening in a second direction, which is perpendicular to the first direction. When the stop plate is in the disengagement position, the stop plate is spaced apart from the opening. This invention achieves rapid alignment of the wrench opening with the nut by the contact between the stop plate located in the stop position and the nut, thus improving the wrench's operating efficiency.

[0004] The wrenches described above and in existing technologies are usually single-type wrenches. When faced with the need to tighten different types of bolts or nuts, it is usually necessary to carry multiple different types of wrenches or wrench heads for interchange. This is very inconvenient to carry and wastes time changing wrenches, affecting work efficiency. There is a lack of a structure that is easy to carry and contains multiple interchangeable wrench heads, which needs to be improved and optimized. Utility Model Content

A vertical pressing post is fixedly connected to one end of each locking buckle, and a second spring is connected to one end of each vertical pressing post.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a retractable multi-purpose wrench, which mainly consists of an inner and outer wrench body that can be plugged in and retracted. The two ends of the inner and outer wrench bodies are respectively connected to a wrench assembly head with an adjustable wrench head size. The rotation of the wrench assembly head can be locked and unlocked by a pin, a first spring, and a handle.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-6 The present invention provides the following two preferred embodiments:

[0024] Example 1: A retractable multi-purpose wrench includes an outer wrench body 1, with an inner wrench body 2 inserted into one end of the outer wrench body 1. A first wrench assembly head 3 is rotatably connected to the other end of the outer wrench body 1. A second wrench assembly head 4 is rotatably connected to one end of the inner wrench body 2, and a fixed telescopic component 5 is provided at the other end of the inner wrench body 2. Two sets of rotating circular holes 101 are symmetrically provided at one end of the outer wrench body 1, and two sets of pin grooves 102 are symmetrically provided at one end of the outer wrench body 1. Multiple sets of locking grooves 106 are provided on the inner side of the outer wrench body 1, and two sets of sliding track grooves 107 are symmetrically provided in the middle of the outer wrench body 1. The pin grooves 102 are movable within the... A pin 103 is inserted, and a first spring 104 is fixedly connected to the middle of the pin 103. A handle 105 is fixedly connected to one end of the pin 103. Two sets of rotating round holes 101 are symmetrically provided at one end of the inner wrench body 2, and two sets of pin grooves 102 are symmetrically provided at one end of the inner wrench body 2. A fixed telescopic component 5 is provided at the other end of the inner wrench body 2. Two sets of rotating shafts 301 are symmetrically provided on both sides of the first wrench combination head 3, and multiple sets of insertion and fixing holes 302 are symmetrically provided on both sides of the first wrench combination head 3. Two sets of rotating shafts 301 are symmetrically provided on both sides of the second wrench combination head 4, and multiple sets of insertion and fixing holes 302 are symmetrically provided on both sides of the second wrench combination head 4.

[0025] In use, one end of the outer wrench body 1 and the inner wrench body 2 are respectively connected to a first wrench assembly head 3 and a second wrench assembly head 4 containing various wrench heads of different models. The first wrench assembly head 3 and the second wrench assembly head 4 can switch between different models of wrench heads by rotating the shaft 301 in the rotating hole 101. Before switching, the handle 105 is pulled outward by hand at the same time. The handle 105 pulls the pin 103 away from the fixing hole 302, and the wrench assembly head can be rotated to switch between different models of wrench heads. When the switching is completed, the handle 105 is released by hand, and the pin 103 is inserted into the fixing hole 302 under the restoring pull of the first spring 104 to fix the wrench assembly head.

[0026] Example 2: Based on Example 1, the fixed telescopic component 5 includes a locking compression groove 501. Two sets of locking buckles 502 are symmetrically inserted into both ends of the locking compression groove 501. A vertical pressing post 503 is fixedly connected to one end of the locking buckle 502, and a second spring 504 is connected to one end of the vertical pressing post 503.

[0027] During use and when storing, the inner and outer wrench bodies can be adjusted for extension and retraction. When in use, pull the inner wrench body 2 out to the longest point of the outer wrench body 1. The locking buckles 502, which are symmetrically arranged on the inner wrench body 2, are inserted into the locking groove 106 at the outer end of the outer wrench body 1 to lock it in place. When finished, press the vertical pressing post 503 inward to pull the locking buckle 502 inward to disengage it from the locking groove 106. This allows the inner wrench body 2 to retract to the shortest point of the outer wrench body 1. Loosen the vertical pressing post 503, and the locking buckle 502, under the restoring compression of the second spring 504, inserts into the innermost locking groove 106 of the outer wrench body 1, thus achieving the retraction and fixation of the inner and outer wrench bodies.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
