[0021] By adopting the above technical solution, when the worm 4 rotates, the worm 4 and the worm wheel 5 are meshed. Since the worm wheel 5 remains stationary, the worm 4 is connected through the fixed seat 3 and the C-shaped fixed block 2. As the worm 4 rotates, the fixed seat 3, the C-shaped fixed block 2 and the glue gun 1 are driven to tilt at an angle. At the same time, the C-shaped fixed block 2 is tilted at an angle on the corresponding two semicircles 8, so that the tilt angle between the glue gun 1 and the bracket 7 can be adjusted according to the desired and comfortable grip posture. The operation is simple and suitable for anyone.

[0022] The tops of the two semicircles 8 are penetrated by arc grooves 10, and the lower surface of the arc grooves 10 is provided with a fixing plate 11. The middle of the fixing plate 11 is threadedly connected with a bolt 12 corresponding to the circular hole 14, and the bottom of the bolt 12 is fixedly installed with a nut 13.

[0023] By adopting the above technical solution, when the nut 13 is rotated, the bolt 12 is driven to rotate, thereby connecting the U-shaped fixing block 2 with the corresponding semicircle 8 respectively, providing a stable shape when the U-shaped fixing block 2 is tilted.

[0024] The opposite ends of the two semicircles 8 are each provided with a first semicircular groove 9 , and the diameter of the first semicircular groove 9 is smaller than the diameter of the semicircle 8 .

[0025] By adopting the above technical solution and setting the first semicircular groove 9, the bolt 12, the fixing plate 11 and the nut 13 can be better installed, and it is more convenient to connect the bolt 12 and the C-shaped fixing block 2 together, and fix the C-shaped fixing block 2 and the corresponding semicircle 8.

[0026] Two symmetrically distributed circular holes 14 are formed at the bottom of the U-shaped fixing block 2 and in the second semicircular groove 19 .

[0035] By adopting the above technical solution, when the rotating wheel 17 is rotated, the rotating shaft 16 is driven to rotate. Since the rotating shaft 16 is arranged on the worm 4, the worm 4 is driven to rotate. At the same time, by arranging the anti-slip strip 18, the friction force when the hand contacts the rotating wheel 17 is increased.

[0036] Working principle: In specific operation, firstly, the second semicircular groove 19 at the bottom of the C-shaped fixing block 2 is brought into contact with the top of the semicircle 8, and then the bolt 12 is inserted into the circular hole 14 on the C-shaped fixing block 2 through the cooperation between the bolt 12, the fixing plate 11 and the nut 13, so that the two semicircles 8 and the C-shaped fixing block 2 are fixed together;

[0037] When it is necessary to adjust the inclination angle between the glue gun 1 and the bracket 7, rotate the rotating wheel 17, and the rotating wheel 17 drives the rotating shaft 16 to rotate. The rotating shaft 16 is set on the worm 4, thereby driving the worm 4 to rotate, and the worm 4 and the worm wheel 5 are meshed, and the worm wheel 5 remains stationary. The worm 4 is connected with the fixed seat 3 and the C-shaped fixed block 2. As the worm 4 rotates, the fixed seat 3, the C-shaped fixed block 2, and the glue gun 1 are driven to tilt. At the same time, the C-shaped fixed block 2 is tilted on the corresponding two semicircles 8, so that the inclination angle between the glue gun 1 and the bracket 7 can be adjusted according to the desired and comfortable grip. The operation is simple and suitable for anyone.
