Problems solved by technology

[0004] However, the above-mentioned method of fixing the nozzle holder to the air piping by using a turnbuckle or a small screw requires the operator to use both hands to replace the nozzle, which takes time and effort to replace the nozzle, resulting in low operating efficiency. question
[0005] Moreover, in the above methods used in the past, since the direction of the nozzle holder relative to the air piping is not unique, it is difficult to determine the position of the nozzle holder. If the direction of the nozzle holder needs to be changed, the turnbuckle or small screw must be loosened first. Turning the nozzle holder and then fine-tuning it is very inefficient for changing the direction of the nozzle

Abstract

A hot air removable nozzle comprising a nozzle holder (2) having an introducing portion (2c) and a hook-like locking portion (2d), an attachment (3), and a cover (4) vertically relatively displaceable by a fixed amount with respect to the attachment (3) and having a locking pin (4a), wherein the locking pin (4a) is introduced into the locking portion (2d) through the introducing portion (2c) of the nozzle holder (2), and a force applied from an urging member (5) to the nozzle holder (2) through the locking pin (4a) acts to elastically press mating portions against each other that are formed on the nozzle holder (2) and attachment (3), thus removably fixing the nozzle holder (2) to the attachment (3).

Description

technical field [0001] The invention relates to a detachable hot gas nozzle suitable for a hot gas injection heating device used when disassembling various surface mounting components. Background technique [0002] Detachable hot gas nozzles suitable for hot gas injection heating devices generally have a nozzle holder that supports the nozzle for spraying hot gas, and a pipe fixing member for connecting the nozzle holder and air piping, and the nozzle holder is fixed by this pipe fixing member on the air piping. [0003] As a method of fixing the nozzle holder to the air piping, such as Figure 4 As shown, generally, the clamping device 8 for mounting the nozzle holder to the air piping 7 is integrally fixed at the end of the base of the nozzle holder 2, and the clamping device is tightened after the nozzle holder 2 is inserted into the air piping 7 8 on the turnbuckle 9 way. In addition, other fixing methods can also be used, such as setting small screws on the side of th...
