Abstract
The utility model relates to a light steel joist rongeur, comprising two rongeur arms, gyration centres, and a working blade. The light steel joist rongeur is characterized in that the working blade is a punching hitter assembled from a formed punch and a formed punch holder; gyration centres of the two rongeur arms are two in number; the formed punch holder is a transverse U-shaped profiled bar which is composed of an upper crossbeam and a lower crossbeam; the gyration centres of the two rongeur arms are arranged on the lower crossbeam; a formed punch hole is arranged on the lower crossbeam between the gyration centres to enable the formed punch to move to-and-fro. A die cavity hole with a diameter larger than the diameter of the formed punch is arranged on the upper crossbeam, opposite to the formed punch hole. The head of the formed punch is a cone structure and an actively connected three-point thrust arm which takes the shape of the Chinese character Ba (the number eight) is connected at the rear end of the formed punch; one point of the thrust arm is arranged at the rear end of the formed punch and the other two are respectively arranged on the two rongeur arms. The light steel joist rongeur has the advantages that the light steel joist rongeur requires no electric power source and is particularly applicable in filed operations; the tools are convenient to use and easy to operate; the light steel joist is firm in connection after being punched and riveted and is high in work efficiency and good in quality.
Description
Technical field
The utility model relates to a kind of pliers, particularly discloses a kind of lightgage steel joist pincers, is used for connecting between the lightgage steel joist, plays a kind of effect of riveting gun.
Background technology
As everyone knows, be used for the connection of lightgage steel joist to adopt common electricians' plier, metal pincers they can not be competent at, often adopt spot-welding equipment or air gun to rivet and finish, these equipment investments are big, use cumbersomely, have electric current just can finish usually, bring some difficulties for the field work meeting.
Summary of the invention
The purpose of this utility model is to overcome the defective in the existing equipment, discloses a kind of lightgage steel joist pincers, uses the utility model as using common electricians' plier convenient, just can finish the connection of lightgage steel joist.
The utility model is achieved in that a kind of lightgage steel joist pincers, comprise tong arm, the centre of gyration, work edge, it is characterized in that: described work edge be drift and punch holder be combined into dash riveting gun, the centre of gyration of two tong arms has two points, punch holder is " Contraband " font shaped steel, " Contraband " font shaped steel comprises, sill, establish the centre of gyration of two tong arms on the described sill, sill between described two centres of gyration is provided with the bore of the punch that drift is gone here and there back and forth, the entablature on described bore of the punch opposite is provided with the die cavity hole of diameter greater than bore of the punch, described drift head is cone-shaped, the drift rear end connects the drift thrust arm that " eight " font bikini flexibly connects, a point of described thrust arm is located at the drift rear end, and two other point minute is located on two tong arms.
Described thrust arm connects also to be provided with between point makes the open spring of two tong arms.
The terminal edge cover of described two tong arms makes the afterburning handle of tong arm spreading.
Described two tong arm cross sections be "
" font shaped steel.
The afterburning handle material of described two tong arms is engineering plastics.
The beneficial effects of the utility model are: the utility model is the manual small tool of a kind of machinery, need not switch on during use, the field work particularly suitable, the lightgage steel joist that instrument is easy to use, operation is simple and easy, connect through the overshoot riveting is connected firmly, and efficiency of construction height, quality are good.
Description of drawings
Fig. 1 is lightgage steel joist structure charts to be connected such as the utility model;
Fig. 2 is that the utility model operation lightgage steel joist is realized the connection state structure chart.
Among the figure: 1, tong arm; 2, drift; 3, punch holder; 4, thrust arm; 5, spring; 6, afterburning handle; 7, lightgage steel joist to be clamped; 8, clamped the lightgage steel joist of connection.
The specific embodiment
According to Fig. 1, a kind of lightgage steel joist pincers, comprise tong arm 1, the centre of gyration, work edge, described work edge be drift 2 and punch holder 3 be combined into dash riveting gun, the centre of gyration of two tong arms has two points, punch holder 3 is " Contraband " font shaped steel, " Contraband " font shaped steel comprises, sill, establish the centre of gyration of two tong arms on the described sill, sill between two centres of gyration is provided with the bore of the punch that drift is gone here and there back and forth, the entablature on bore of the punch opposite is provided with the die cavity hole of diameter greater than bore of the punch, drift 2 heads are cone-shaped, drift 2 rear ends connect the drift thrust arm 4 that " eight " font bikini flexibly connects, and a point of thrust arm is located at the drift rear end, and two other point minute is located on two tong arms 1; Described thrust arm 4 connects also to be provided with between point makes the open spring 5 of two tong arms; Two tong arms, 1 terminal edge cover makes the afterburning handle 6 of tong arm spreading; Two tong arms, 1 cross section be "
" font shaped steel; Afterburning handle 6 materials of two tong arms 1 are engineering plastics.
During use, two hold tight afterburning handle 6, two tong arms 1 inwardly step up, " eight " font drift thrust arm 4 pushes away drift 2 forward, very big by leverage drift forward thrust, under the effect of drift 1 and punch holder 3 mo(u)ld top half lumen pores, will wait to step up lightgage steel joist 7 and become as having clamped the lightgage steel joist 8 of connection among Fig. 2 towards riveting.The connection of two lightgage steel joists through the utility model just very the realization of light and fast connect towards riveting.
