Abstract
The utility model provides an elastic positioning piece, which comprises a pin arm and a C-shaped tensioning arm, wherein the C-shaped tensioning arm is an elastic piece with an opening at one side and is in a C shape, one end of the pin arm is connected with a middle concave part of the C-shaped tensioning arm.
Description
Technical Field
The utility model relates to a hardware fitting, in particular to an elastic positioning piece.
Background
The electric knocking wrench is a tool for disassembling bolts commonly, when the bolts are disassembled, in order to prevent the sleeve from being separated from the wrench head, the sleeve is generally firstly arranged on a square sleeve head of the electric wrench, then a pin penetrates through a pin hole of the sleeve and a pin hole of the wrench sleeve head to be fixed, meanwhile, in order to prevent the pin from being separated when the bolts are disassembled, an elastic leather ring is sleeved outside the sleeve, and the pin is blocked by the elastic leather ring. The sleeve of different specifications needs to be replaced when the bolts with different specifications are detached, so that the apron and the pin are required to be detached repeatedly, and in the working environment of high-altitude operation or mess, the pin and the apron are two separated parts, so that the pin and the apron are very easy to lose during disassembly, the working efficiency is influenced, and unnecessary waste is caused.
Disclosure of Invention
The utility model aims to improve the defects in the prior art and provides an elastic positioning piece with a novel structure.
The technical scheme of the utility model is as follows: an elastic locating piece is characterized by comprising a pin arm and a C-shaped tensioning arm, wherein the C-shaped tensioning arm is an elastic piece with an opening at one side in a C shape, and one end of the pin arm is connected with a middle concave part of the C-shaped tensioning arm.
Further preferred is that the pin arm and the C-shaped tensioning arm are of unitary construction.
Compared with the prior art, the utility model combines the traditional pin and the leather collar into an integral structure, designs the pin arm and the C-shaped tensioning arm, and forms an integral component after the pin arm and the C-shaped tensioning arm are connected, and the pin arm and the C-shaped tensioning arm are simultaneously installed and completed when in use, thereby not only solving the complexity of the split structure in the prior art, but also completely ensuring the matching firmness of the sleeve and the spanner head and saving the installation time and the loss cost. Compared with the prior art, the utility model has the advantages of simple and novel structure, convenient operation, low cost and the like, and has good market application prospect.
The utility model is explained in detail below with reference to the drawings and the examples.
Drawings
FIG. 1-a schematic view of a construction of the present utility model.
Fig. 2-an application schematic diagram of the utility model.
Reference numerals illustrate:
a pin arm 1, a tensioning arm 2C, a 3 electric wrench, a 4 sleeve, a 5 sleeve pin hole, a 6 apron groove and a 7 wrench pin hole.
Description of the embodiments
Referring to fig. 1, an elastic positioning piece is composed of a pin arm 1 and a C-shaped tensioning arm 2, wherein the C-shaped tensioning arm 2 is an elastic piece with an opening at one side in a C shape, and one end of the pin arm 1 is connected with a middle concave part of the C-shaped tensioning arm 2. The pin arm 1 and the C-shaped tensioning arm 2 can be made of metal materials or hard plastic materials, one end of the pin arm 1 and the C-shaped tensioning arm 2 can be connected in a welding, bonding and other modes, and the pin arm 1 and the C-shaped tensioning arm 2 are preferably directly manufactured into an integral structure by adopting an injection molding process.
The method of use is described as follows:
referring to fig. 2, the existing socket 4 and electric wrench 3 are unchanged in structure, the socket 4 is provided with a socket pin hole 5, a leather collar groove 6 is arranged at the position of the socket pin hole 5, and the electric wrench 3 is provided with a wrench pin hole 7.
When the electric spanner is used, the sleeve 4 is firstly inserted into the electric spanner 3, the sleeve pin hole 5 is aligned with the spanner pin hole 7, then the pin arm 1 of the elastic positioning piece is aligned with the sleeve pin hole 5 (spanner pin hole 7) to be inserted, meanwhile, the two side tensioning arms of the C-shaped tensioning arm 2 are elastically opened along the leather ring groove 6, after the pin arm 1 is inserted, the two side tensioning arms of the C-shaped tensioning arm 2 are held tightly against the leather ring groove 6, and the installation is completed.
When the sleeve 4 needs to be replaced, the two side tensioning arms of the C-shaped tensioning arm 2 are pushed in the opposite direction, so that the C-shaped tensioning arm 2 is reversely pulled out along the leather collar groove 6, meanwhile, the pin arm 1 is pulled out of the sleeve pin hole 5 (the spanner pin hole 7), the elastic locating piece is taken down, and the sleeves 4 with different specifications are replaced.
In the utility model, the opening size of the C-shaped tensioning arm needs to ensure that the elastic locating piece cannot be separated from the wrench due to the rotation centrifugal force in the using process of the wrench, so that the elastic locating pieces with different opening sizes are designed according to different specifications of the wrench or the sleeve and the product materials for manufacturing the elastic locating pieces.
