A pushing part extending from the lower part of the front end of the moving block can reciprocate through the extending opening, and an inclined first guiding surface is formed on the rear end surface of the moving block;

[0007] An elastic member, which is arranged in the receiving cavity. One end of the elastic member is connected to the front inner wall of the fixed seat, and the other end of the elastic member is connected to the front end surface of the moving block;

An inclined second guiding surface is formed on the end surface of the pushing member facing the moving member, and the second guiding surface cooperates with and slides on the first guiding surface; wherein, the second direction is perpendicular to the first direction.

[0009] In a possible implementation manner, the bottom surface of the pushing part is flush with the bottom surface of the moving block, and the bottom surface of the moving block is lower than the bottom surface of the fixed seat.

[0010] In a possible implementation manner, one end of the pushing part away from the moving block is arc-shaped.

[0011] In a possible implementation manner, a first mounting hole is formed on the front end surface of the moving block, and a second mounting hole is formed on the front inner wall of the fixed seat. The second mounting hole and the first mounting hole are on the same horizontal line, and both ends of the elastic member are respectively inserted into the first mounting hole and the second mounting hole.

[0012] In a possible implementation, the elastic member is a spring.

[0013] In a possible implementation, a threaded hole extending in the second direction is formed in the pushing member, and an adjusting member is threadedly connected in the threaded hole. The adjusting member is used to adjust the reciprocating movement of the pushing member in the second direction.

[0028] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details.

[0029] Please refer to Figures 1 to 3 , this application provides an adjustment mechanism for the position of a nozzle, including a fixed seat 10, a moving block 20, an elastic member 30, and a pushing member 40. An accommodation cavity 10a is formed inside the fixed seat 10, and an extension opening communicating with the accommodation cavity 10a is provided on the front surface of the fixed seat 10. The moving block 20 is disposed in the accommodation cavity 10a and can reciprocate in a first direction. A pushing portion 21 that can reciprocally pass through the extension opening extends from the lower part of the front end of the moving block 20, and an inclined first guiding surface 20b is formed on the rear end surface of the moving block 20. The elastic member 30 is disposed in the accommodation cavity 10a. One end of the elastic member 30 is connected to the front inner wall of the fixed seat 10, and the other end of the elastic member 30 is connected to the front end surface of the moving block 20. The pushing member 40 is disposed in the accommodation cavity 10a and can reciprocate in a second direction. An inclined second guiding surface 40b is formed on the end surface of the pushing member 40 facing the moving member, and the second guiding surface 40b cooperates with and slides on the first guiding surface 20b. Among them, the second direction is perpendicular to the first direction.

[0030] Exemplarily, the elastic member 30 can be a spring. One end of the spring is connected to the front inner wall of the fixed seat 10, and the other end of the elastic member 30 is connected to the front surface of the moving block 20. When the moving block 20 is pushed by the pushing member 40 and moves in the accommodation cavity 10a towards the extension opening direction, the spring is compressed and in a compressed state. At this time, the pushing portion 21 extends out of the extension opening to push the nozzle to the required position; when the pushing of the pushing member 40 is released, the spring pushes the moving member back to the initial position due to its own resilience. At this time, the pushing portion 21 retracts from the extension opening into the accommodation cavity 10a, and there is no need to manually push the moving block 20 back into the accommodation cavity 10a.

[0031] It should be noted that pushing the pushing member 40 to move in the second direction can be achieved by manually pressing it. After being pushed to the appropriate position, a fastener is used for locking, so that the pushing portion 21 of the moving block 20 extends out of the extension opening by the required length, thereby adjusting the nozzle to the required position. Of course, the pushing member 40 can also be automatically pressed by an automatic member (such as an electric telescopic rod).

[0032] The adjusting mechanism for the position of the nozzle based on the above technical features forms an inclined second guiding surface 40b on the end face of the pushing member 40 facing one end member, and forms an inclined first guiding surface 20b on the rear end face of the moving block 20. The first guiding surface 20b and the second guiding surface 40b cooperate with each other and slide. When the pushing member 40 is pushed to move in the second direction, the moving block 20 is pushed to move in the receiving cavity 10a, so as to control the pushing portion 21 to extend or retract from the outlet, so that the staff can simply and quickly adjust the position of the nozzle arbitrarily. At the same time, after releasing the pushing on the pushing member 40, the moving block 20 can be pushed back to the initial position by the resilience of the elastic member 30 itself, without manually pushing the moving block 20 back into the receiving cavity 10a.

[0033] In a possible implementation manner, the bottom surface of the pushing portion 21 is flush with the bottom surface of the moving block 20, and the bottom surface of the moving block 20 is lower than the bottom surface of the fixed seat 10. Based on the fact that the bottom surface of the moving block 20 is set lower than the bottom surface of the fixed seat 10, when the pushing member 40 pushes the moving block 20 to move in the receiving cavity 10a, the bottom surface of the moving block 20 will not directly contact the bearing surface, so as to reduce the resistance received by the moving block 20 and make the sliding of the moving block 20 smoother.

[0034] In a possible implementation manner, one end of the pushing portion 21 away from the moving block 20 is arc-shaped.

[0035] In a possible implementation manner, a first mounting hole 20a is formed on the front end face of the moving block 20, and a second mounting hole 10b is formed on the front inner wall of the fixed seat 10. The second mounting hole 10b and the first mounting hole 20a are located on the same horizontal line, and both ends of the elastic member 30 are respectively inserted into the first mounting hole 20a and the second mounting hole 10b.

[0036] Exemplarily, both ends of the elastic member 30 are respectively inserted into the first mounting hole 20a and the second mounting hole 10b for fixation, so that the elastic member 30 can only be compressed in the first direction when being squeezed, and will not slide in the second direction, thereby ensuring that the elastic member 30 can normally push the moving block 20 back into the receiving cavity 10a.

[0037] In a possible implementation manner, a threaded hole 40a extending in the second direction is formed on the pushing member 40, and an adjusting member is threadedly connected in the threaded hole 40a. The adjusting member is used to adjust the reciprocating movement of the pushing member 40 in the second direction. In this way, when it is necessary to push the moving block 20 to move, only the adjusting member needs to be turned, so that the pushing member 40 is pushed to move in the second direction, and then the moving block 20 is pushed to move in the receiving cavity 10a. The structure is simple and the adjustment is convenient.

[0038] In a possible implementation, the pushing part 21 and the moving block 20 are an integral part or separate parts. That is to say, the pushing part 21 and the moving block 20 can be made by an integral molding process, or the pushing part 21 and the moving block 20 form two separate structures, and after the pushing part 21 and the moving block 20 are molded, they are then connected.

[0039] Specifically, the pushing part 21 and the moving block 20 are an integral part, which can save the connection between the pushing part 21 and the moving block 20 and ensure the overall structural strength.

[0040] In a possible implementation, two symmetrical connecting ears 50 extend outward from both sides of the fixed seat 10, and fixing holes 50a are formed in the connecting ears 50. In this way, after the fixed seat 10 is placed on the mounting plate, the fixing holes 50a are aligned with the connecting holes on the mounting plate, and then bolts are used to pass through the fixing holes 50a and the connecting holes in sequence, and the fixed seat 10 can be quickly installed on the mounting plate, with a simple structure and convenient disassembly and assembly.

[0041] It can be understood that the above embodiments only represent the preferred implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present invention; therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention shall fall within the scope covered by the claims of the present invention.
