[0020] The technical solutions in the present application will be further described below in combination with the drawings and embodiments.

[0021] Embodiment:

[0022] As shown in Figure 1 and Figure 2 A glue gun includes a glue gun body 1 and a trigger 9 provided on the glue gun body 1. A connecting pipe 2 is provided on the glue outlet of the glue gun body 1. A nozzle 3 is provided on the connecting pipe 2. A ball valve 4 is provided in the connecting pipe 2. An anti-misoperation component for preventing the glue gun body 1 from being misoperated is provided on the ball valve 4. An anti-dripping component for preventing the nozzle 3 from dripping is provided on the anti-misoperation component.

[0023] As shown in Figure 1 and Figure 2 , the anti-mistouch assembly includes a connecting plate 5 and a connecting rod 6, the connecting plate 5 is slidingly arranged on the glue gun body 1, the connecting rod 6 is fixedly arranged on the connecting plate 5, and the connecting rod 6 is used to abut the side opposite to the pulling direction of the trigger 9 after the connecting plate 5 slides, as shown in Figure 1 and Figure 2 , the glue gun body 1 is fixedly provided with a sliding seat 7, and the connecting plate 5 is provided with a sliding groove 8, and the sliding seat 7 and the sliding groove 8 are slidingly connected, as shown in Figure 3 , the ball valve 4 is provided with a valve rod 10, the valve rod 10 is fixedly provided with a gear 11, the connecting plate 5 is fixedly provided with a rack 12, and the gear 11 and the rack 12 are meshed with each other, as shown in Figure 1 and Figure 2 , the valve rod 10 is fixedly provided with a handle 13.

[0024] When the operator finishes spraying glue on the furniture, the operator can rotate the handle 13, the handle 13 drives the valve rod 10 to rotate, the valve rod 10 drives the ball valve 4 to rotate, and then the ball valve 4 closes the connecting pipe 2, thereby achieving the sealing effect. When the valve rod 10 rotates, the gear 11 on the valve rod 10 also rotates, the gear 11 drives the rack 12 to move, and then the gear 11 drives the connecting plate 5 to move, the sliding groove 8 on the connecting plate 5 slides on the sliding seat 7 of the glue gun body 1, so that the movement of the connecting plate 5 drives the connecting rod 6 to move, and the connecting rod 6 moves to abut the trigger 9, thereby preventing the operator from accidentally touching the trigger 9 of the glue gun when not using the glue gun, which causes the glue to be sprayed.

[0025] As shown in Figure 1 and Figure 2 , the anti-drip assembly includes a rotating block 14 and a hinged rod 15, the rotating block 14 is rotatably arranged on the connecting pipe 2, and the hinged rod 15 is hingedly arranged on the connecting plate 5 and the other end of the hinged rod 15 is hingedly connected with the rotating block 14, as shown in Figure 1 and Figure 2 , the rotating block 14 is provided with a recess 16, a pin shaft 17 is arranged in the recess 16, a sliding block 18 is slidingly arranged on the pin shaft 17, and the sliding block 18 is hingedly connected with the hinged rod 15.

[0026] When the operator finishes spraying glue on the furniture, the movement of the connecting plate 5 drives the movement of the hinged rod 15, and the hinged rod 15 pushes the sliding block 18 when moving, so that the sliding block 18 can move on the pin shaft 17. When the sliding block 18 moves, the rotating block 14 rotates due to the movement of the hinged rod 15. When the connecting plate 5 moves to the position, the rotating block 14 blocks the connecting pipe 2, thereby preventing the residual glue in the connecting pipe 2 from leaking out.

[0027] As shown in Figure 1 andFigure 2 As shown, the connecting plate 5 is fixed with a limiting block 19 opposite to the handle 13.

[0028] The limiting block 19 can prevent the handle 13 from excessive rotation, and the operator can indicate the switch state of the handle 13 according to the position of the limiting block 19 and the handle 13.

[0029] Working principle:

[0030] When the operator finishes spraying glue on the furniture, the operator can rotate the handle 13, the handle 13 drives the valve rod 10 to rotate, the valve rod 10 drives the ball valve 4 to rotate, and then the ball valve 4 closes the connecting pipe 2, thereby achieving the sealing effect. When the valve rod 10 rotates, the gear 11 on the valve rod 10 also rotates, the gear 11 drives the rack 12 to move, and then the gear 11 drives the connecting plate 5 to move, the sliding groove 8 on the connecting plate 5 slides on the sliding seat 7 of the glue gun body 1, thereby the movement of the connecting plate 5 drives the connecting rod 6 to move, the connecting rod 6 moves and abuts against the trigger 9, thereby preventing the operator from spraying glue due to accidental touch of the glue gun trigger 9 when not using the glue gun.

[0031] When the operator finishes spraying glue on the furniture, the movement of the connecting plate 5 drives the movement of the hinged rod 15, the hinged rod 15 pushes the sliding block 18 when moving, so that the sliding block 18 can move on the pin shaft 17. When the sliding block 18 moves, the rotating block 14 rotates due to the movement of the hinged rod 15. When the connecting plate 5 moves to the position, the rotating block 14 blocks the connecting pipe 2, thereby preventing the residual glue in the connecting pipe 2 from leaking out.

[0032] The limiting block 19 can prevent the handle 13 from excessive rotation, and the operator can indicate the switch state of the handle 13 according to the position of the limiting block 19 and the handle 13.
