Description

Technical Field

[0001] This utility model relates to the field of glue guns, and in particular to a glue gun with a cutting blade that makes operation easier. Background Technology

[0002] Chinese Patent No. CN220969762U discloses a manual glue gun, including a handle and a trigger. The handle is provided with a cutting component that can cut the nozzle to make a glue outlet. The cutting component includes two mounting seats arranged parallel to each other at the upper end of the handle, a cutting blade arranged between the two mounting seats with one end hinged to the two mounting seats, and an insertion hole provided on the mounting seats for the nozzle to be inserted.

[0003] In the above structure, the nozzle can be inserted into the socket on the mounting base when the cutting blade rotates out of the mounting base. After the nozzle is inserted into the socket, the cutting blade can be rotated into the mounting base. As the cutting blade rotates into the mounting base, it will cut the nozzle inserted into the socket to create an outlet. However, when the cutting blade rotates into the mounting base and comes into contact with the nozzle surface, the nozzle will increase the damping of the cutting blade rotation, making it more difficult for the operator to operate the cutting blade to cut the outlet on the nozzle. Utility Model Content

[0004] This invention addresses the drawback of existing glue guns where the nozzle inserted into the socket increases the damping of the cutting blade's subsequent rotation when it comes into contact with the cutting blade, making it difficult for the operator to cut the glue outlet on the nozzle. This invention provides a glue gun with a cutting blade that is easier to operate.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A glue gun with a cutting blade for easy operation includes a handle, a trigger, and a cutting component for cutting the nozzle to create an outlet. The cutting component includes a mounting base, a cutting opening on the mounting base for inserting the nozzle, and a cutting blade that is hinged to the mounting base at one end and cuts the nozzle into the cutting opening. The mounting base is located on the handle opposite to the trigger. When the cutting blade opens the cutting opening, it is positioned between the trigger and the mounting base. When the trigger is engaged towards the handle, the cutting blade is driven by the trigger to close the cutting opening. The length of the rotating arm of the trigger is greater than the length of the rotating arm of the cutting blade.

[0007] Using the above solution, the mounting base is set on the handle opposite to the trigger position. When the cutting blade opens the cutting opening, the trigger is pulled towards the handle, and the trigger will drive the cutting blade to move and close the cutting opening. Since the rotating arm of the trigger is larger than the rotating arm of the cutting blade, it is more labor-saving to drive the cutting blade to cut the nozzle inserted into the cutting opening by the trigger than to directly rotate the cutting blade to cut the nozzle.

[0008] Preferably, the end of the cutter away from its hinge to the mounting base is provided with a locking structure that restricts the rotation of the cutter and an unlocking component for releasing the locking state between the cutter and the mounting base.

[0009] Preferably, the snap-fit ​​structure includes a snap-fit ​​block disposed on the cutting blade, a mounting block disposed in the mounting base, and a snap-fit ​​groove disposed on the mounting block for inserting the snap-fit ​​block and engaging with the inserted snap-fit ​​block.

[0010] Using the above solution, the locking block on the cutting blade can be inserted into the slot on the mounting block. When the locking block is inserted into the slot, the locking block and the inner wall of the slot will engage with each other, thereby restricting the cutting blade from rotating and reducing the probability of injury to the user when using the glue gun.

[0011] Preferably, the unlocking component includes a sliding space between the mounting base and the handle for the mounting block to move therein, and a pushing component for the operator to push the mounting block to move within the sliding space. When the pushing component pushes the mounting block to a first position within the sliding space, the locking block and the locking slot are in a corresponding engagement state; when the pushing component pushes the mounting block to a second position within the sliding space, the locking block and the locking slot are misaligned.

[0012] Using the above solution, the sliding space between the mounting base and the handle allows the mounting block to slide within it, thereby enabling the locking or misalignment between the slot and the block on the mounting block. When the block and the slot are locked, the rotation of the cutting blade is restricted; when the block and the slot are misaligned, the cutting blade can rotate. The push component allows the operator to easily push the mounting block within the sliding space.

[0013] Preferably, the pushing component includes a pushing block provided on the mounting block and extending along the moving direction of the mounting block, and a guide groove provided on the mounting base for guiding the pushing block to move therein, with one end of the pushing block away from the mounting block extending out of the guide groove.

[0014] Using the above scheme, the push block set on the mounting block can be guided and moved in the guide groove on the mounting base. Since the end of the push block away from the guide groove extends out of the guide groove, the operator can push the push block that extends out of the guide groove to push the mounting block to move in the sliding space.

[0015] Preferably, a reset spring is provided between the mounting block and the handle, which causes the mounting block to return to the first position when the push block pushes the mounting block to the second position.

[0016] With the above solution, the reset spring can drive the mounting block back to the first position when the push block moves the mounting block to the second position and the push block drives the operator to push it. This makes it convenient for the locking block on the cutting blade and the locking groove on the mounting block to engage with each other when the cutting blade closes the cutting edge.

[0017] Preferably, a torsion spring is provided at the location away from the locking structure of the cutting blade, which drives the cutting blade to rotate away from the mounting block when the unlocking component releases the locking state between the cutting blade and the mounting base.

[0018] Using the above solution, the torsion spring located at the point where the cutter is far from the locking structure can push the cutter to gradually open the cutting opening when the unlocking component releases the locking between the cutter and the mounting base. When cutting the nozzle later, simply rotate the cutter towards the mounting block to cut the glue outlet on the nozzle, thus making the use of the cutter more convenient.

[0019] This utility model has significant technical effects due to the adoption of the above technical solutions: the mounting base is set on the handle opposite to the trigger position, and when the cutting blade opens the cutting opening, the trigger is pulled towards the handle, and the trigger will drive the cutting blade to move and close the cutting opening. Since the rotating arm of the trigger is larger than the rotating arm of the cutting blade, it is more labor-saving to drive the cutting blade to cut the nozzle inserted into the cutting opening by the trigger than to directly rotate the cutting blade to cut the nozzle.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] A glue gun with a cutting blade for easy operation, reference Figure 1 The device includes a handle 1, a trigger 2, and a cutting component for cutting the nozzle to create an outlet. The cutting component includes a mounting base 4, a cutting end 3 provided on the mounting base 4 for inserting the nozzle, and a cutting blade 5 provided on the mounting base 4 with one end hinged to the mounting base 4 to cut the nozzle inserted into the cutting end 3 to create an outlet. The mounting base 4 is located on the handle 1 opposite to the trigger 2. When the cutting blade 5 opens the cutting end 3, the cutting blade 5 is located between the trigger 2 and the mounting base 4. When the trigger 2 is engaged towards the handle 1, the cutting blade 5 is driven by the trigger 2 to close the cutting end 3. The length of the rotating arm of the trigger 2 is greater than the length of the rotating arm of the cutting blade 5.

[0030] refer to Figures 2-7 The cutting blade 5, away from its hinged end to the mounting base 4, has a locking structure between itself and the mounting base 4 to restrict the rotation of the cutting blade 5, and an unlocking component for releasing the locking state between the cutting blade 5 and the mounting base 4. The locking structure includes a locking block 6 on the cutting blade 5, a mounting block 13 inside the mounting base 4, and a slot 7 on the mounting block 13 for the locking block 6 to be inserted and for engaging with the inserted locking block 6. The unlocking component includes a sliding space 8 between the mounting base 4 and the handle 1 for the mounting block 13 to move therein, and a mechanism for the operator to push. The pushing component that moves the mounting block 13 within the sliding space 8 has the following characteristics: when the pushing component pushes the mounting block 13 to the first position within the sliding space 8, the locking block 6 and the locking groove 7 are in a corresponding engagement state; when the pushing component pushes the mounting block 13 to the second position within the sliding space 8, the locking block 6 and the locking groove 7 are misaligned. The pushing component includes a pushing block 9 provided on the mounting block 13 and extending along the moving direction of the mounting block 13, and a guide groove 10 provided on the mounting base 4 for guiding the pushing block 9 to move therein. The end of the pushing block 9 away from the mounting block 13 extends out of the guide groove 10.

[0031] refer to Figures 5-6 A reset spring 11 is provided between the mounting block 13 and the handle 1, which drives the mounting block 13 to return to the first position when the push block 9 pushes the mounting block 13 to the second position.

[0032] refer to Figures 2-3A torsion spring 12 is provided at the location away from the locking structure of the cutting blade 5, which drives the cutting blade 5 to rotate away from the mounting block 13 when the unlocking component releases the locking state between the cutting blade 5 and the mounting base 4.

[0033] The specific cutting process of the nozzle: When a glue outlet needs to be cut on the nozzle, firstly, press the push block 9, causing the push block 9 to move the mounting block 13 to the second position within the sliding space 8. At this time, the locking block 6 on the cutting blade 5 will be misaligned with the locking groove 7 on the mounting block 13. The torsion spring 12 located at the end of the cutting blade 5 away from the locking structure will push the cutting blade 5 to open the cutting opening 3. Then, insert the nozzle into the cutting opening 3. Next, press the trigger 2, causing the trigger 2 to move the cutting blade 5 in the direction of closing the cutting opening 3. When the cutting blade 5 comes into contact with the nozzle inserted into the cutting opening 3, as the cutting blade 5 rotates, the cutting blade 5 will partially cut off the nozzle, thus forming a glue outlet on the nozzle. Because the rotating arm of the trigger 2 is larger than the rotating arm of the cutting blade 5, it is more labor-saving to rotate the cutting blade 5 by the trigger 2 to cut the nozzle.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
