Abstract
Description
Technical Field
[0001] This utility model relates to the field of glue guns, and more particularly to a glue gun with a nozzle cutting part. 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 device that can cut the nozzle to make a glue outlet. The cutting device includes two mounting seats that are parallel and spaced apart at the upper end of the handle. A cutting blade with one end hinged to the two mounting seats is provided between the two mounting seats. The two mounting seats are provided with an insertion hole for the nozzle to be inserted.
[0003] The cutting blade in the above structure, which is installed between the two mounting bases and hinged to the two mounting bases at one end, can cut the nozzle inserted into the socket to create a glue outlet. However, the cutting blade is only connected to the two mounting bases at one end by a hinge, and the cutting blade is prone to rotate automatically in the mounting base, causing the blade end on the cutting blade to detach from the mounting base, thereby increasing the probability of accidental injury to the operator when using the glue gun. Utility Model Content
[0004] This invention addresses the drawback of existing cutting blades where the blade end easily detaches from the mounting base, increasing the probability of operator injury during use. It provides a glue gun with a nozzle cutting component that reduces the probability of operator injury during use.
[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 nozzle cutting component includes a handle, a trigger, and a cutting component disposed on the handle for cutting the nozzle to create a glue outlet. The cutting component includes a mounting base disposed on the handle, an insertion hole disposed on the mounting base for inserting the nozzle, and a cutting blade disposed within the mounting base for cutting the nozzle inserted into the insertion hole to create a glue outlet. One end of the cutting blade is pivotally connected to the mounting base, and the other end is provided with a locking structure between the cutting blade and the mounting base to restrict the rotation of the cutting blade, as well as an unlocking component to release the locking state between the cutting blade and the mounting base.
[0007] The above solution utilizes a locking structure between the mounting base and the cutting blade to restrict the cutting blade's rotation when it enters the mounting base. This reduces the likelihood of the cutting blade rotating away from the mounting base and dislodging during use, thus lowering the probability of injury to the operator. The unlocking mechanism releases the locking mechanism when a nozzle needs to be cut, allowing the cutting blade to rotate away from the mounting base. When the cutting blade rotates away from its pivot point and out of the mounting base, the nozzle can be inserted into the socket. Once the nozzle is inserted, rotating the cutting blade towards the mounting base will cut the nozzle.
[0008] 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.
[0009] 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.
[0010] Preferably, the unlocking component includes a sliding space provided in the mounting base 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.
[0011] Using the above scheme, the sliding space set in the mounting base allows the mounting block to slide within it, thereby achieving the engagement or misalignment between the slot and the block on the mounting block. When the block and the slot are engaged, 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.
[0012] 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.
[0013] 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.
[0014] Preferably, a reset spring is provided between the mounting block and the inner wall of the sliding space, which drives the mounting block to return to the first position when the pushing block pushes the mounting block to the second position.
[0015] Using the above solution, the reset spring located between the mounting block and the inner wall of the sliding space can drive the mounting block to reset and move it back to the first position when the pushing block loses the operator's pushing force after it has moved the mounting block to the second position. At the same time as the mounting block resets, the pushing block also resets, which facilitates the next pushing of the pushing block. Since the reset spring can drive the mounting block to reset to the first position when the pushing block loses the operator's pushing force, when the cutting blade rotates towards the mounting block, the locking block on the cutting blade can be inserted into the locking groove on the mounting block, thereby reducing the probability of the cutting blade falling out of the mounting base and reducing the probability of operator injury during use.
[0016] 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.
[0017] Using the above solution, the torsion spring located away from the locking structure of the cutting blade can push the cutting blade to rotate away from the mounting block when the unlocking component releases the locking between the cutting blade and the mounting base. When cutting the nozzle later, you only need to rotate the cutting blade towards the mounting block to cut the glue outlet on the nozzle, thus making the use of the cutting blade more convenient.
[0018] Preferably, a detachable part is provided between the bottom of the cutter and the handle to allow for the assembly and disassembly of the two.
[0019] Preferably, the detachable component includes a mounting plate disposed below the cutting blade and a mounting slot disposed near the top of the handle for inserting the mounting plate.
[0020] Using the above solution, the mounting plate located below the cutting blade can be inserted into the mounting slot located near the top of the handle, thereby realizing the installation between the cutting blade and the handle.
[0021] This utility model, by adopting the above technical solutions, has significant technical effects: the locking structure set between the mounting base and the cutting blade can restrict the rotation of the cutting blade when it rotates into the mounting base, reducing the likelihood of the cutting blade rotating away from the mounting base and dislodging from it when using the glue gun, thereby reducing the probability of operator injury when using the glue gun. The unlocking component can release the locking state between the cutting blade and the mounting base when a glue outlet needs to be cut on the nozzle. At this time, the cutting blade can rotate away from the mounting base. When the cutting blade rotates away from the end pivotally connected to the mounting base and moves outside the mounting base, the nozzle can be inserted into the socket. After the nozzle is inserted into the socket, rotating the cutting blade towards the mounting base will cut a glue outlet on the nozzle. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0032] Example
[0033] A glue gun with a nozzle cutting part, reference Figure 1 The device includes a handle 1, a trigger 2, and a cutting component on the handle 1 that can cut the nozzle to create an outlet. The cutting component includes a mounting base 3 on the handle 1, an insertion hole 4 on the mounting base 3 for inserting the nozzle, and a cutting blade 5 inside the mounting base 3 that can cut the nozzle inserted into the insertion hole 4 to create an outlet. One end of the cutting blade 5 is pivotally connected to the mounting base 3, and the other end is provided with a locking structure that restricts the rotation of the cutting blade 5 and an unlocking component that releases the locking state between the cutting blade 5 and the mounting base 3.
[0034] refer to Figures 2-4 , Figure 6 The snap-fit structure includes a snap-fit block 6 on the cutting blade 5, a mounting block 7 in the mounting base 3, and a snap-fit groove 8 on the mounting block 7 for inserting the snap-fit block 6 and engaging with the inserted snap-fit block 6.
[0035] refer to Figure 5 The unlocking component includes a sliding space 9 provided in the mounting base 3 for the mounting block 7 to move therein, and a pushing component to facilitate the operator to push the mounting block 7 to move within the sliding space 9. A reset spring 12 is provided between the mounting block 7 and the inner wall of the sliding space 9, which drives the mounting block 7 to return to the first position when the pushing block 10 pushes the mounting block 7 to the second position. When the pushing component pushes the mounting block 7 to the first position within the sliding space 9, the locking block 6 and the locking groove 8 are in a corresponding engagement state. In this embodiment, the first position refers to the position of the mounting block 7 when the cutting blade 5 rotates towards the mounting block 7 and the locking block 6 can be inserted into the locking groove 8 on the mounting block 7. When the pushing component pushes the mounting block 7 to the second position within the sliding space 9, the locking block 6 and the locking groove 8 are misaligned.
[0036] refer to Figure 6 A torsion spring 13 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 7 when the unlocking component releases the locking state between the cutting blade 5 and the mounting base 3.
[0037] refer to Figures 4-5 , Figure 8 The pushing component includes a pushing block 10 provided on the mounting block 7 and extending along the moving direction of the mounting block 7, and a guide groove 11 provided on the mounting base 3 for guiding the pushing block 10 to move therein, with one end of the pushing block 10 away from the mounting block 7 extending out of the guide groove 11.
[0038] refer to Figures 7-8A detachable component is provided between the bottom of the cutter 5 and the handle 1 to enable the assembly and disassembly of the two. The detachable component includes a mounting plate 14 provided below the cutter 5 and a mounting groove 15 provided near the top of the handle 1 for the mounting plate 14 to be inserted. In this embodiment, the mounting plate 14 is "L" shaped, thereby reducing the probability that the mounting plate 14 will come out from above the mounting groove 15 when it is inserted into the mounting groove 15.
[0039] The specific cutting process of the nozzle: When the nozzle needs to cut out the glue outlet, firstly, push the push block 10 into the sliding space 9. At this time, the push block 10 will drive the mounting block 7 to move within the sliding space 9. When the mounting block 7 moves to the second position within the sliding space 9, the locking block 6 on the cutting blade 5 disengages from the locking groove 8. At this time, the torsion spring 13 set at the point away from the locking structure of the cutting blade 5 will push the cutting blade 5 to rotate in the direction away from the mounting block 7. After the cutting blade 5 rotates, the nozzle can be inserted into the insertion hole 4. Then, rotate the cutting blade 5 in the opposite direction. When the cutting blade 5 rotates to abut against the surface of the nozzle, as the cutting blade 5 continues to rotate, the cutting blade 5 can cut out the glue outlet on the nozzle.
