Hand-hold pliers body structure for mechanical coupling

Abstract

The invention relates to a hand-held clipper body structure used in mechanical connection, belongs to the technical field of hardware tools and comprises a first handle bar, a second handle bar, a die mechanism, a top part, a female die driving mechanism, a pull rod and an elastic part; wherein, the upper part of the first handle bar forms a clipper head with a clipper head groove; the second handle bar is articulated with the first handle bar; the die mechanism which is formed by matching a female die and a male die is arranged on the clipper head; the top part is positioned at one end of the upper part of the second handle bar in a rotary way; the female die driving mechanism is movably arranged in the clipper head groove; the pull rod is used for driving a bar linkage to move, and one end of the pull rod is connected with the bar linkage while the other end of the pull rod is connected with the second handle bar; the elastic part which is used for ensuring the reset of the female die is positioned in the clipper head groove and is contacted with the female die. The hand-held clipper body structure has the advantages of saving raw and auxiliary materials, embodying the green construction, saving the construction cost and improving the working efficiency as well as ensuring the reliability of the connection.

Description

technical field [0001] The invention belongs to the technical field of hardware tools, and in particular relates to a pliers structure for hand-held mechanical connection. Background technique [0002] In architectural decoration projects, light steel keels are widely used. In order to achieve an organic connection between light steel keels, core-pulling aluminum rivets are usually used for fastening connections or self-tapping screws or special snap-in pieces. Connect by welding or other similar means. The above-mentioned traditional mechanical connection method has the following disadvantages: First, when using core-pulling aluminum rivets or self-tapping screws to implement mechanical connection between light steel keels, in addition to pre-drilling with electric drills, it is also necessary to use fasteners as fasteners. Core-pulling aluminum rivets or self-tapping screws, resulting in high noise at the job site, large consumption of fasteners, and limited by the power ...

Problems solved by technology

The above-mentioned traditional mechanical connection method has the following disadvantages: First, when using core-pulling aluminum rivets or self-tapping screws to implement mechanical connection between light steel keels, in addition to pre-drilling with electric drills, it is necessary to use fasteners as fasteners. Core-pulling aluminum rivets or self-tapping screws, resulting in high noise at the job site, large consumption of fasteners, and limited by the power supply conditions at the job site, because if there is no power supply, construction cannot be done, and if there is power supply, it will also consume Electric energy is used; the second is that when using special snap-on parts to connect, in addition to consuming the snap-on parts, the construction efficiency will be low, and the strength cannot be guaranteed; the third is that when the two parts are implemented by welding When connecting between parts, there is not only a waste of solder, but also serious damage to the components, making it difficult to guarantee the quality of the connection

[0003] The applicant has observed for a long time and found that for the self-coupling or inter-coupling operation methods between iron sheets, stainless steel, and thin steel plates, including the above-mentioned light steel dragon frame, the thickness of which is usually less than 0.5mm, regardless of the above-mentioned any Either method inevitably has the disadvantages of large energy consumption, high noise, low work efficiency, serious waste of materials, high cost and poor connection reliability, and, contrary to the green and environmental protection construction requirements promoted by the Ministry of Construction of my country, is trapped in the above operations The method will produce architectural decoration waste, such as metal shavings when drilling, and the use of core-pulling aluminum rivets will produce discarded aluminum rivet rods
