On the other hand, it also causes serious glue waste. In some work scenarios, the single glue output is too small, and multiple glue applications are required to fill the gluing surface, resulting in low gluing efficiency and affecting construction efficiency. Summary of the invention

[0003] The purpose of the present invention includes providing a glue gun handle and a glue gun to alleviate the technical problem in the prior art that the amount of glue discharged from the glue barrel cannot be controlled when using the glue gun to apply glue.

[0004] The embodiment of the present invention adopts the following technical solution:

[0005] In the first aspect, an embodiment of the present invention provides a glue gun handle, comprising a top connecting piece, a locking plate, a glue gun push rod, a driving block, a driving spring, a fixed handle and a movable handle; the locking plate is obliquely connected to the rear end of the top connecting piece by a spring, and the glue gun push rod passes through the locking plate and the top connecting piece; the driving block is slidably connected to the glue gun push rod; the driving spring is sleeved on the glue gun push rod, and one end of the driving spring abuts against the front end surface of the driving block, and the other end of the driving spring is used to abut against the gun body of the glue gun; the upper end of the fixed handle is fixedly connected to the lower end of the top connecting piece; the upper end of the movable handle is pivotally connected to the inside of the top connecting piece, and the movable handle is located at the front side of the fixed handle; the driving block is hinged to the upper end of the movable handle or the lower end of the driving block abuts against the front side of the upper end of the movable handle;

[0006] Wherein: a glue output amount adjustment component is installed on the movable handle;

[0007] The glue output amount adjustment component includes a drive shaft and a drive shaft positioning member;

[0008] The upper end of the movable handle is provided with a mounting groove, and the parts on both sides of the mounting groove form handle mounting parts, and the two handle mounting parts are arranged on the left and right sides of the top connecting member; the top connecting member is provided with a movable handle mounting hole that passes through the top connecting member in the left-right direction, and the two handle mounting parts are respectively provided with drive shaft mounting holes that pass through the handle mounting parts in the left-right direction, and the drive shaft passes through the drive shaft mounting hole on one handle mounting part, the movable handle mounting hole and the drive shaft mounting hole on the other handle mounting part in sequence, and both ends of the drive shaft are provided with anti-slip structures, and the drive shaft rotates synchronously with the two handle mounting parts;

[0009] A driving protrusion, a first positioning groove and a second positioning groove are provided on the outer circumferential surface of the driving shaft at a position between the two handle mounting parts; a positioning member mounting hole is provided on at least one of the handle mounting parts, the positioning member mounting hole is communicated with the driving shaft mounting hole, the driving shaft positioning member is installed in the positioning member mounting hole, and one end of the driving shaft positioning member extends into the driving shaft mounting hole;

[0051] Embodiment 1

[0052] A glue gun is a glue-applying tool. Figure 1 and Figure 2 As shown, the glue gun currently in use includes a glue gun push rod 1, a glue gun handle 2 and a gun body 3 connected to the front end of the glue gun handle 2. The glue gun handle 2 includes a fixed handle 21, a movable handle 22 and a top connecting piece 23 having a through hole 231 for inserting the glue gun push rod 1; the upper end of the fixed handle 21 is fixedly connected to the lower end of the top connecting piece 23, wherein the fixed handle 21 can be fixedly connected to the lower end of the top connecting piece 23 by screws, rivets or other fixings, or can be an integrally formed structure with the top connecting piece 23; the upper end of the movable handle 22 is pivotally connected to the inside of the top connecting piece 23, and the movable handle 22 is located at the front side of the fixed handle 21; wherein the glue gun handle 2 also includes a locking plate 24 that is hingedly connected to the rear end of the top connecting piece 23 by a spring, a through hole is provided on the locking plate 24, and the glue gun push rod 1 passes through the through hole 231 on the top connecting piece 23 and the through hole on the locking plate 24, and the rear end of the glue gun push rod 1 is located outside the top connecting piece 23, and the front The end extends to the interior of the gun body 3; a driving block 4 is slidably arranged on the glue gun push rod 1; the driving block 4 is hinged to the upper end of the movable handle 22 or the lower end of the driving block 4 abuts against the front side of the upper end of the movable handle 22, and a driving spring 5 is also sleeved on the glue gun push rod 1, and one end of the driving spring 5 abuts against the driving block 4 and the other end abuts against the gun body 3, wherein the manner in which the end of the driving spring 5 close to the gun body 3 abuts against the gun body 3 includes but is not limited to, a sleeve-shaped connecting portion is provided at the rear end of the gun body 3, the outer peripheral surface of the connecting portion is provided with a thread, the front end of the top connecting member 23 is sleeved and threadedly connected to the outside of the connecting portion, the glue gun push rod 1 passes through the connecting portion, and the end of the driving spring 5 close to the gun body 3 extends into the interior of the connecting portion and abuts against the rear end surface of the gun body 3; under the action of the spring between the locking plate 24 and the top connecting member 23, the glue gun push rod 1 is locked in the through hole of the locking plate 24.

[0053] When in use, the locking plate 24 is pressed to extend the locking plate 24 in the vertical direction and release the glue gun push rod 1, the glue gun push rod 1 is pulled to move the front end of the glue gun push rod 1 backward and then release the locking plate 24, the glue cartridge is placed inside the gun body 3 with the glue outlet facing forward, and the movable handle 22 is pulled backward. At this time, the upper end of the movable handle 22 can tilt the driving block 4 so that the driving block 4 locks the glue gun push rod 1, and at the same time, the upper end of the movable handle 22 pushes the driving block 4 forward to drive the glue gun push rod 1 to overcome the friction between the perforation of the locking plate 24 and the glue gun push rod 1 and move forward, so that the front end of the glue gun push rod 1 squeezes the rear end of the glue cartridge placed inside the gun body 3, thereby causing the glue cartridge to discharge glue; the driving block 4 will compress the driving spring 5 during the forward movement, and the driving spring 5 makes the driving block 4 and the movable handle 22 always have a movement tendency to return to their original position, so that when the movable handle 22 is released, the driving block 4 returns to its original position and returns to its original position, and the glue is applied repeatedly.

[0054] In the prior art, when using a glue gun to apply glue, it is impossible to control the amount of glue output from the glue barrel, resulting in excessive glue output in some work scenarios. On the one hand, this will cause great interference to the process and require unnecessary cleaning work for the excess glue on the gluing surface. On the other hand, it also causes serious glue waste. In some work scenarios, the single glue output is too small, and multiple glue applications are required to fill the gluing surface, resulting in low gluing efficiency and affecting construction efficiency.

[0055] In contrast, this embodiment provides a glue gun handle, referring to Figures 2 to 12 In the structure of the glue gun handle, a glue output amount adjustment component 100 is installed on the movable handle 22, and the glue output amount of the glue gun can be adjusted by the glue output amount adjustment component 100.

[0056] Especially refer to Figures 6 to 9Specifically, the glue output amount adjustment component 100 includes a drive shaft 110 and a drive shaft positioning member 120; a mounting groove is provided at the upper end of the movable handle 22, and the parts on both sides of the mounting groove form handle mounting parts, and the two handle mounting parts are arranged on the left and right sides of the top connecting member 23; a movable handle mounting hole is provided on the top connecting member 23 that passes through the top connecting member 23 in the left-right direction, and the two handle mounting parts are respectively provided with drive shaft mounting holes 221 that pass through the handle mounting parts in the left-right direction, and the drive shaft 110 passes through the drive shaft mounting hole 221 on one handle mounting part, the movable handle mounting hole and the drive shaft mounting hole 221 on the other handle mounting part in sequence, and anti-slip structures 300 are provided at both ends of the drive shaft 110, and the drive shaft 110 rotates synchronously with the two handle mounting parts. A driving protrusion 1101, a first positioning groove 1102 and a second positioning groove 1103 are provided on the outer circumferential surface of the driving shaft 110 at a position between the two handle mounting parts; a positioning member mounting hole 222 is provided on at least one handle mounting part, and the positioning member mounting hole 222 is connected to the driving shaft mounting hole 221, and the driving shaft positioning member 120 is installed in the positioning member mounting hole 222, and one end of the driving shaft positioning member 120 extends into the driving shaft mounting hole 221. The driving shaft 110 can slide left and right relative to the two handle mounting parts, so that in the first position, the end of the driving shaft positioning member 120 located in the driving shaft mounting hole 221 is stuck in the first positioning groove 1102, and in the second position, the end of the driving shaft positioning member 120 located in the driving shaft mounting hole 221 is stuck in the second positioning groove 1103; when the driving shaft 110 is in the first position, the end of the driving protrusion 1101 away from the driving shaft 110 can press the driving block 4 forward while the driving shaft 110 rotates forward; when the driving shaft 110 is in the second position, the driving protrusion 1101 avoids the driving block 4.

[0057] The structure of the glue gun handle provided in this embodiment has two usage conditions:

[0058] The first operating condition is suitable for situations where a larger amount of glue is required, such as Figure 6 As shown, the operator pushes the drive shaft 110 so that the drive shaft 110 is in the first working position, that is, the end of the drive shaft positioning member 120 located in the drive shaft mounting hole 221 is stuck in the first positioning groove 1102. At this time, the end of the driving protrusion 1101 away from the drive shaft 110 can press the drive block 4 forward while the drive shaft 110 rotates forward. When the drive shaft 110 contacts the drive block 4, the driving ratio is large, the glue output is large, and it is suitable for glue with low viscosity.

[0059] The second operating condition is suitable for situations where a smaller amount of glue is required, such as Figure 7As shown, the operator pushes the drive shaft 110 in the reverse direction so that the drive shaft 110 is in the above-mentioned second working position, that is, the end of the drive shaft positioning member 120 located in the drive shaft mounting hole 221 is stuck in the second positioning groove 1103. At this time, the driving protrusion 1101 avoids the driving block 4, and the driving shaft 110 has a smaller propulsion ratio when in contact with the driving block 4, and the glue output is smaller, which is suitable for glue with higher viscosity.

[0060] In this embodiment, a glue output adjustment component 100 is installed on the movable handle 22 of the glue gun to realize the thrust ratio gear switching function and change the glue feed amount of the glue gun. Therefore, the actual glue output of the glue gun can be adjusted according to actual needs, ensuring the construction process while avoiding unnecessary cleaning work, and having the effect of saving glue, which is more conducive to rapid construction.

The main shaft 111 includes a first shaft section 1111 and a second shaft section 1112 which are connected in one piece. The outer diameter of the radial section of the first shaft section 1111 is larger than the outer diameter of the radial section of the second shaft section 1112. The first positioning groove 1102 and the second positioning groove 1103 are arranged on the outer peripheral surface of the first shaft section 1111. The driving protrusion 1101 is cam-shaped, and the driving protrusion 1101 and the sleeve 112 are both sleeved on the outside of the second shaft section 1112. One side surface of the driving protrusion 1101 abuts against the end surface of the first shaft section 1111 facing one end of the second shaft section 1112, and the other side surface of the driving protrusion 1101 abuts against the end surface of the sleeve 112 facing one end of the first shaft section 1111. One end of the first shaft segment 1111 away from the second shaft segment 1112 is inserted into the drive shaft mounting hole 221 of one handle mounting part, and one end of the second shaft segment 1112 away from the first shaft segment 1111 and one end of the sleeve 112 away from the first shaft segment 1111 are both inserted into the drive shaft mounting hole 221 of the other handle mounting part.

[0064] In some other optional implementations of this embodiment, as another glue gun handle, refer to Fig.13 and Fig.14 The driving protrusion 1101 is fixedly connected or integrally connected to the outer circumferential surface of one end of the driving shaft 110, and the first positioning groove 1102 and the second positioning groove 1103 are both provided on the driving protrusion 1101; the driving protrusion 1101 is inserted into the driving shaft mounting hole 221 of one handle mounting part, and the end of the driving shaft 110 away from the driving protrusion 1101 is inserted into the driving shaft mounting hole 221 of the other handle mounting part; the anti-detachment structure 300 can prevent the driving shaft 110 and the driving protrusion 1101 from detaching from the corresponding driving shaft mounting hole 221.
