[0032] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents. The "radial" and "axial" in this application are relative to the soldering iron tip, and "radial" can correspond to "lateral" and "axial" can correspond to "longitudinal".

[0033] like Figure 1-Figure 4 A soldering iron tip quick switching auxiliary device is shown, on which a plurality of different types of soldering iron tips 1 are hung, each soldering iron tip 1 comprises a connecting rod 101 for detachably connecting with a soldering handle 4 and a soldering head 102 for performing soldering, the connecting rod 101 is located at the upper end of the soldering head 102, and the soldering handle 4 is a universal structure, which can form different types of electric soldering irons when connected with the connecting rods 101 of different types of soldering iron tips 1;

[0034] The auxiliary device includes a base 2, on which a plurality of storage cavities are provided. The plurality of storage cavities correspond to the plurality of soldering iron tips 1 one by one, and each storage cavity is used for the corresponding soldering iron tip 1 to enter radially for storage. In this embodiment, there are four storage cavities, and two groups are formed symmetrically, wherein the opening direction of one group of storage cavities is opposite to the opening direction of the other group of storage cavities, and the lower cavities 202 of the two storage cavities in the same group are connected to each other. The storage cavity includes an upper cavity 201 located at the upper part for accommodating the connecting rod 101 and a lower cavity 202 located at the lower part for accommodating the welding head 102. A step is formed between the upper cavity 201 and the lower cavity 202. The upper cavity 201 is expanded at one end away from the lower cavity 202 to form a positioning groove 203. The middle part of the connecting rod 101 protrudes with a protrusion 1011 for inserting the positioning groove 203 to limit the axial movement of the soldering iron tip 1, such as Figure 6 and Figure 7 As shown; when the soldering iron tip 1 enters the receiving cavity radially, the protrusion 1011 is aligned with the positioning groove 203 to be inserted into the positioning groove 203, and the upper groove wall and the lower groove wall of the positioning groove 203 restrict the protrusion 1011 therebetween to prevent it from moving up and down.

[0035] During operation, firstly, various types of soldering iron tips 1 are radially inserted into the storage cavity, the connecting rod 101 enters the upper cavity 201, the welding head 102 enters the lower cavity 202, and at the same time, the protrusion 1011 enters the positioning groove 203, and the upper groove wall and the lower groove wall of the positioning groove 203 restrict the protrusion 1011 therebetween to restrict the axial movement of the soldering iron tip 1, and then the welding handle 4 can be connected to different types of soldering iron tips 1 according to different welding requirements to form different types of electric soldering irons, the electric soldering iron can be moved downward to achieve docking with the soldering iron tip 1, and can be moved upward to achieve separation from the soldering iron tip 1.

[0036] In some examples, a balancing mechanism 3 is elastically provided in the upper cavity 201 for limiting the connecting rod 101 to prevent it from tilting; since the soldering tip 1 can enter and exit the storage cavity radially, there is a gap between the cavity wall of the storage cavity and the soldering tip 1 to avoid interference with the entry and exit of the soldering tip 1. The existence of the gap may cause the soldering tip 1 to tilt in the storage cavity, and the balancing mechanism 3 can be used to position the soldering tip 1.

[0037] In some examples, the balancing mechanism 3 includes a mounting groove 204 connected to the upper cavity 201, an abutment body for abutting the connecting rod 101 is slidably mounted in the mounting groove 204, an elastic element is arranged between the abutment body and the groove bottom of the mounting groove 204 to realize the elastic setting of the abutment body, during the insertion process of the connecting rod 101, the connecting rod 101 overcomes the elastic force of the elastic element and is inserted, and the abutment body abuts against the outer wall of the connecting rod 101 to limit the soldering iron tip 1 inside the storage cavity, so as to prevent the soldering iron tip 1 from escaping from the storage cavity in the radial direction;

[0038] In some examples, the upper cavity 201 and the lower cavity 202 are both groove structures, and the upper notch 201a of the upper cavity 201, the lower notch 202a of the lower cavity 202, and the notch 203a of the positioning groove 203 are all located on the side of the base 2 to enable the soldering iron tip 1 to enter and exit the storage cavity in the radial direction, and the upper cavity 201 passes through the top end surface of the base 2 upward, such as Figure 7 shown.

[0039] In some examples, each upper cavity 201 is provided with two sets of balancing mechanisms 3, wherein the balancing mechanism 3 located at the upper portion is used to abut against the protrusion 1011, and the balancing mechanism 3 located at the lower portion is used to abut against the lower end of the connecting rod 101. The two sets of balancing mechanisms 3 can increase the force acting on the soldering iron tip 1. In addition, the balancing mechanisms 3 distributed up and down are farther apart, so that the force acting on the connecting rod 101 is more uniform, preventing the soldering iron tip 1 from tilting, and the two sets of balancing mechanisms 3 in the same storage cavity are located on the same side of the connecting rod 101.

[0040] In some examples, the abutment body is a ball 301, and a notch 1012 is provided on the side wall of the protrusion 1011 to cooperate with the ball 301. The notch 1012 is an arc-shaped structure that cooperates with the spherical ball 301. The ball 301 is stuck into the notch 1012 under the elastic force of the elastic element, thereby improving the locking effect of the ball 301 on the soldering iron tip 1.

[0041] In some examples, the ball 301 in the lower balancing mechanism 3 abuts against the outside of the connecting rod 101, which applies an inward force to the connecting rod 101 to limit the connecting rod 101 from radially escaping from the storage cavity. In order to install the ball 301 on the outside of the connecting rod 101, the cross-section of the upper cavity 201 is U-shaped instead of semicircular, so that the side wall of the upper cavity 201 has sufficient installation space.

[0042] In some examples, the two side groove walls 2031 of the positioning groove 203 are arc-shaped structures, and the side surfaces of the protrusion 1011 opposite to the two side groove walls 2031 are also arc-shaped structures, and the four corners of the protrusion 1011 are all provided with rounded corners.

[0043] In some examples, a slot 205 is provided above the positioning slot 203 and is connected to the positioning slot 203 and is used for inserting the plug-in end 401 of the welding handle 4, and the slot 205 is a T-shaped slot that matches the plug-in end 401, and both the plug-in end 401 and the slot 205 are provided with steps; during the replacement process of the soldering iron tip 1, the welding handle 4 gradually moves downward, and the connecting rod 101 of the soldering iron tip 1 to be replaced gradually enters the inner cavity of the welding handle 4 from the plug-in end 401 of the welding handle 4, and when the step on the plug-in end 401 abuts against the step on the slot 205, the soldering iron tip 1 and the welding handle 4 are installed in place, thereby realizing rapid switching between the soldering iron tip 1 and the handle.

[0044] In some examples, a seal 5 is installed inside the plug-in end 401 of the welding handle 4. The seal 5 can be an O-ring. When the welding handle 4 moves down and plugs into the soldering iron tip 1, the O-ring can intercept various oxides on the soldering iron tip 1 to prevent them from entering the interior.

[0045] Working principle:

[0046] During operation, firstly, various types of soldering iron tips 1 are radially inserted into the storage cavity, the connecting rod 101 enters the upper cavity 201, the soldering head 102 enters the lower cavity 202, and the protruding portion 1011 enters the positioning groove 203. The upper groove wall and the lower groove wall of the positioning groove 203 restrict the protruding portion 1011 therebetween to restrict the axial movement of the soldering iron tip 1. During the insertion process of the connecting rod 101, the connecting rod 101 overcomes the elastic force of the elastic element and is inserted. The two balancing mechanisms 3 distributed up and down can lock the soldering iron tip 1 to prevent it from radially escaping from the storage cavity and can prevent it from tilting when stored. Therefore, the elastically arranged ball 301 and the positioning groove 203 respectively restrict the freedom of the soldering iron tip 1 in the radial and axial directions, so that it can be locked, thereby improving the accuracy of the placement of the soldering iron tip 1.

[0047] According to different welding requirements, the welding handle 4 can be connected to different types of soldering iron tips 1 to form different types of electric soldering irons. During the replacement of the soldering iron tip 1, the moving mechanism 6 can drive it to move in three dimensions, such as Figure 5 As shown, the welding handle 4 has a chip identification function, which is convenient for reading welding data and realizing rapid identification of the handle by the moving mechanism 6; the moving mechanism 6 drives the electric soldering iron currently in use to the side of the base 2, and then makes the soldering tip 1 on it enter the storage cavity radially, and then drives the welding handle 4 to move upward. Since the positioning groove 203 limits the freedom of the soldering tip 1 to move upward, the welding handle 4 is separated from the soldering tip 1. Then the moving mechanism 6 drives the welding handle 4 to the top of the soldering tip 1 to be replaced, and drives the welding handle 4 to move downward gradually. The soldering tip 1 to be replaced gradually enters the inner cavity of the welding handle 4 from the plug-in end 401 of the welding handle 4. When the step on the plug-in end 401 abuts against the step on the slot 205, the soldering tip 1 and the welding handle 4 are installed in place, thereby realizing rapid installation between the soldering tip 1 and the handle. At the same time, in the process of the welding handle 4 moving downward and plugging into the soldering tip 1, the O-type rubber ring can intercept various oxides on the soldering tip 1 to prevent them from entering the interior.
