Detailed Description
As shown in fig. 1-4, a wrench extender capable of entering a narrow space comprises sleeves 20 arranged at two ends of a main body 10 and rotating relative to the main body 10, wherein gears 21 are arranged on the sleeves 20, chains 40 meshed with the gears 21 are arranged in the main body 10, the sleeves 20 at two ends of the main body 10 synchronously rotate through the chains 40, the sleeves 20 at one end are sleeved on fasteners such as bolts or nuts, the sleeves 20 at the other end rotate, and at the moment, the two sleeves 20 can simultaneously rotate to realize the function of tightening or loosening the bolts.
The sleeve 20 is provided with a plurality of sleeve holes 22, the shape of the sleeve holes 22 is determined according to the shape of the bolts or nuts, the sleeve holes 22 of the sleeve 20 at two ends can be the same or different, when the sleeve 20 is used, the sleeve 20 at one end is sleeved on a fastener, and the sleeve 20 at the other end is inserted into the sleeve holes 22 for rotation through tools such as a screwdriver head, an allen wrench (if the sleeve holes 22 are hexagonal, the sleeve holes 22 are square in the embodiment) and the like, so that synchronous rotation of the sleeve 20 at two ends is realized.
The main part 10 includes upper shell 11 and inferior valve 12, and upper shell 11 and inferior valve 12 both ends are provided with sleeve mounting hole 13 that cup joints with sleeve 20, are equipped with the joint portion 23 with sleeve mounting hole 13 butt on sleeve 20, make sleeve 20's position fixed through joint portion 23 and the sleeve mounting hole 13 butt of upper and lower shell 12, and main part 10 adopts plastics material to make in this embodiment, and convenient processing saves the cost simultaneously, and the texture is light, convenient to use.
The support post assembly further comprises a support post 30 for supporting the upper shell 11 and the lower shell 12, two ends of the support post 30 extend outwards to form a short shaft 31, a plurality of support post mounting holes 14 are formed between sleeve mounting holes 13 on the upper shell 11 and the lower shell 12 and positioned at two ends, the short shafts 31 at two ends of the support post 30 are respectively inserted into the support post mounting holes 14 of the upper shell 11 and the lower shell 12, and the support post 30 plays a role in supporting in the main body 10.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the utility model, and that simple modifications and substitutions by those skilled in the art are within the scope of the utility model without departing from the spirit and scope of the utility model.
