Detailed Implementation

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0024] like Figure 1 and Figure 2 As shown, the glue gun nozzle cap removal tool designed in this application based on the spacing and external dimensions of the inner and outer nozzle caps at the front end of the existing glue gun includes an upper clamping block 1, a lower clamping block 2, and a connecting pair. The upper clamping block and the lower clamping block of this application are both made of tool steel or suitable steel to ensure the strength of the tool.

[0025] In this application, one end of the upper clamping block 1 and the lower clamping block 2 are hinged together by a pin 3 to form a rotating pair, similar to the hinged structure of a clamp or scissors. One end of the connecting pair is rotatably connected to the other end of the lower clamping block via a connecting shaft 26, and the other end of the connecting pair is movably engaged with the upper clamping block.

[0026] In this application, the upper clamping block 1 includes an upper clamping block body and a connecting block 11 fixedly connected to the upper clamping block body. The upper clamping block body and the connecting block form an L-shape with a large 90-degree angle. A first through hole is provided on the connecting block 11. The pin 3 passes through the first through hole. The connecting block 11 rotates around the pin 3, thereby driving the upper clamping block body to rotate around the pin. The two ends of the pin are fixedly connected to the lower clamping block, thereby realizing the hinged connection between the upper clamping block and the lower clamping block.

[0027] The upper clamping block body and the lower clamping block of this application are provided with an arc-shaped portion 13 and a second arc-shaped portion 14 on their opposite surfaces. The distance and size of the first arc-shaped portion 13 and the second arc-shaped portion 14 are matched with the distance between the inner and outer nozzle covers. The first arc-shaped portion 13 and the second arc-shaped portion 14 of this application are both semi-circular. The first arc-shaped portion 13 is provided with a first chamfer on the side near the pin shaft to avoid interference during clamping.

[0028] In this application, a first opening 12 is provided at the other end of the upper clamping block body. This opening is located at the end of the upper clamping block body and is used to mate with the connecting pair.

[0029] A third arc-shaped portion 15 is provided on the upper end face of the upper clamping block body at a position corresponding to the first opening 12, and the third arc-shaped portion 15 is also semi-circular.

[0030] In this application, the lower clamping block 2 includes a lower clamping block body. A fourth arc-shaped portion 21 and a fifth arc-shaped portion 22 are provided on the opposing surfaces of the lower clamping block body and the upper clamping block body. The fourth arc-shaped portion 21 cooperates with the first arc-shaped portion 13, and the fifth arc-shaped portion 22 cooperates with the second arc-shaped portion 14. In this application, the fourth arc-shaped portion 21 and the fifth arc-shaped portion 22 are also semi-circular. Therefore, the first arc-shaped portion 13 and the fourth arc-shaped portion 21 form a circle, and the second arc-shaped portion 14 and the fifth arc-shaped portion 22 form a circle for cooperating with the inner and outer nozzle caps. After the clamping block is closed, two holes are formed in the middle position. The size of each hole is slightly smaller than the outer diameter of the nozzle cap by 0.1 mm, which makes it easy for the clamping block to clamp tightly and then remove the nozzle cap without damage.

[0031] A second opening 24 is provided at one end of the pin 3 on the lower clamping block body. A first mounting hole is provided on the side of the lower clamping block body corresponding to the second opening 24. A connecting block 11 is provided at the second opening 24. The pin 3 is inserted into the first mounting hole and the first through hole on the connecting block in sequence, and the pin is fixed on the lower clamping block body.

[0032] A third opening 25 is provided at the other end of the lower clamping block body. A second mounting hole 23 is provided on the side of the lower clamping block body corresponding to the third opening. A connecting pair is provided in the third opening 25. The connecting shaft 26 passes through the second mounting hole 23 and the connecting pair in sequence.

[0033] In this application, a second chamfer is provided at the position opposite to the first chamfer on the fourth arc-shaped portion 21, also to avoid interference during the clamping process.

[0034] In this application, the connecting pair includes a rotating block 4, a stud 5, and a butterfly nut 7. A second through hole corresponding to the second mounting hole is provided on the rotating block, and a threaded hole is provided on one end face of the rotating block. One end of the stud is screwed into the threaded hole, and the butterfly nut is threadedly engaged with the other end of the stud.

[0035] The connecting pair also includes a stop block 6, which is a semi-cylindrical structure. Its arc-shaped surface mates with the third arc-shaped part. A third through hole is provided on the stop block. The diameter of the third through hole is larger than the maximum outer diameter of the stud. The stud passes through the third through hole, and then the butterfly nut is screwed onto the stud. In use, the inner and outer nozzle covers are placed within the range of the first, second, fourth, and fifth arc-shaped parts. Then the upper clamp is closed, and the connecting pair is rotated so that the stud enters the first opening. The stop block is placed at the third arc-shaped part, and then the butterfly nut is tightened to complete the clamping of the nozzle cover. The pressure on the nozzle cover is limited and uniform, and it can be removed without damaging the nozzle cover.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
