Further, the colloid is viscous glue which does not drip.

Further, the colloid is a sealant.

Further, the inlet and the outlet are parallel to the end face of the piston.

Further, the inlet and outlet comprises a bevel opening and a straight opening.

Further, when the inlet and the outlet are oblique openings, the end surface of the piston is an oblique surface; when the inlet and the outlet are straight openings, the end surface of the piston is a plane.

Furthermore, the inclination of the inlet and the outlet is determined by the space around the part where the rivet to be glued is located.

Further, the inlet and the outlet are attached to the surface of the part where the rivet to be glued is located, and the diameter of the inlet and the outlet is larger than that of the rivet to be glued.

Advantageous effects

The utility model provides a handheld rubber coating instrument, the quality is light, simple structure, and convenient to use, whether the space is uncovered all can use, once get to glue can apply the rivet button head about 5, can make coating colloid appearance symmetrical, mellow and full, pleasing to the eye, the uniformity is good, can show promotion rubber coating quality, improves rubber coating efficiency.

The utility model comprises 4 drawings, the drawings and the description of the drawings are as follows:

FIG. 1 is a three-view illustration of a hand held glue applicator tool;

FIG. 2 is an isometric view of a form-gluing tool;

FIG. 3 is a schematic view of the manner in which the gluing tool is used;

FIG. 4 is an isometric view of a form two glue application tool;

wherein: 1. the glue injection pipe comprises a glue injection pipe body 2, a piston body 3, a piston shaft 4, coated sealant 5, a rivet 6, a part 7, an oblique-opening glue injection pipe body 8 and an oblique-opening piston.

Detailed Description

The utility model relates to a hand-held gluing tool is explained in detail with the attached drawing:

the utility model provides a handheld rubber coating instrument, as shown in fig. 1, mainly constitute by injecting glue pipe 1, piston 2, piston shaft 3, can have two kinds of forms of flat mouthful and bevel connection, be applicable to the narrow and small position in space open position and space respectively. The piston shaft is connected with the piston, the assembly of the piston shaft and the piston is embedded into the glue injection pipe, the assembly of the piston shaft and the piston can slide along the inner wall of the glue injection pipe under the action of manual pushing force or pulling force, and sealant coating work is completed through movement of the piston. The utility model overcomes the shortcoming that traditional brush rubber coating is inefficient, the manufacturability is poor, the quality is difficult to guarantee provides one kind small, and the quality is light, simple structure, convenient to use, and the wide handheld rubber coating instrument of application scope once gets to glue and can apply the rivet button head about 5, can guarantee that the coating colloid appearance is symmetrical, mellow and full, pleasing to the eye, and the uniformity is good, can show and promote the rubber coating quality, improves rubber coating efficiency.
