The power mechanism is a motor, the motor is in transmission connection with the input end of the gear box, and the output end of the gear box is in transmission connection with the lead screw 1. The locking mechanism 2 is sleeved on the screw rod 1 and used for limiting the movement of the screw rod 1 along the linear direction while not influencing the rotation of the screw rod 1. Be provided with on the handle 20 and beat and glue the button, the operator presses and beats to glue the button and can start motor, and drive lead screw 1 rotates antedisplacement to the realization is progressively beaten and is glued. The structures of the glue gun 100 related to the gluing process are all the prior art, and are not described herein.
As shown in fig. 2 to 4, the lock mechanism 2 includes a first lock sleeve 21, a second lock sleeve 22, and a stopper bead 23. The first locking sleeve 21 and the second locking sleeve 22 are both sleeve-shaped structures, the inner diameter of the second locking sleeve 22 is larger than the outer diameter of the first locking sleeve 21, and the second locking sleeve 22, the first locking sleeve 21 and the lead screw 1 are sequentially nested from outside to inside.
The inner wall surface of the second locking sleeve 22 is provided with an accommodating groove 221, optionally, the accommodating groove 221 is a plurality of annular grooves arranged at intervals along the axial direction of the second locking sleeve 22, and the cross-sectional shape of the annular groove is semicircular. The first locking sleeve 21 is provided with a plurality of limiting through holes 211, optionally, the limiting through holes 211 are circular holes, the number of the limiting through holes 211 is multiple, and the plurality of limiting through holes 211 are uniformly distributed on the first locking sleeve 21.

The position-limiting bead 23 can be located at two different positions, a first position and a second position, depending on the relative positions of the first locking sleeve 21 and the second locking sleeve 22. The first position is that the lower part of the limiting ball 23 is positioned in a thread groove of the screw rod 1, the upper part of the limiting ball 23 is positioned in a limiting through hole 211 of the first locking sleeve 21, and at this position, because the limiting ball 23 locks the relative position of the screw rod 1 and the first locking sleeve 21, the limiting effect is exerted on the screw rod 1, the screw rod 1 cannot move along the linear direction, the screw rod 1 can only rotate and displace, and at this time, the whole locking mechanism 2 is in a limiting state; the second position is that the position-limiting ball 23 is located in the containing groove 221 of the second locking sleeve 22, at this time, because the position-limiting ball 23 is not in contact with the screw rod 1, the screw rod 1 can freely move in the first locking sleeve 21 along the linear direction, and at this time, the whole locking mechanism 2 is in an unlocked state.
When the relative positions of the first locking sleeve 21 and the second locking sleeve 22 are changed under the action of external force, the limiting bead 23 can be interchanged between the first position and the second position, that is, the limiting bead 23 can roll from the first position partially located in the limiting through hole 211 and partially located in the thread groove to the second position completely located in the accommodating groove 221, or can roll from the second position completely located in the accommodating groove 221 to the first position partially located in the limiting through hole 211 and partially located in the thread groove.
In order to drive the limiting ball 23 to move from the first position to the second position, the relative positions of the first locking sleeve 21 and the second locking sleeve 22 in the axial direction need to be changed, in the embodiment, the first locking sleeve 21 is driven by external force, so that the first locking sleeve 21 can be axially drawn out of at least partial structure from the inside of the second locking sleeve 22, as shown in fig. 3, a stop ring 24 is arranged at the end part of the first locking sleeve 21, the stop ring 24 is clamped on the first locking sleeve 21, and when the locking mechanism 2 is in an unlocking state, and external force along the axial direction of the screw 1 is applied to the stop ring 24, the first locking sleeve 21 can be gradually drawn out from the inside of the second locking sleeve 22.
In order to unlock the lead screw 1 with one hand, namely, when an operator holds the glue gun 100 with one hand, the stop ring 24 can be applied with force, so that the operability of the glue gun 100 is improved, and the labor intensity of the operator is reduced. As shown in fig. 2 to 6, the glue gun 100 further includes an unlocking mechanism 3, and the unlocking mechanism 3 includes an unlocking button 31, a shift lever 32, a turn sleeve 33, and a bushing 34. The unlock button 31 is disposed on the housing 10 of the glue gun 100, and as shown in fig. 1, the unlock button 31 is located near the handle 20 of the glue gun 100, and pressing the unlock button 31 causes the unlock button 31 to move linearly in a first direction. The rotary sleeve 33 and the bushing 34 are both sleeve-shaped structures, and are sleeved outside the second locking sleeve 22 side by side along the axial direction of the screw rod 1. The middle part of the shift lever 32 is hinged on the shell 10 of the glue gun 100, one end of the shift lever is in transmission connection with the unlocking button 31, and the other end of the shift lever is in transmission connection with the outer wall of the rotary sleeve 33, so that when the unlocking button 31 is pressed, one end of the shift lever 32 can rotate along with the shift lever, and the other end of the shift lever can drive the rotary sleeve 33 to rotate around the axis direction of the lead screw 1. In the present embodiment, the direction in which the unlock button 31 is pressed is set perpendicular to the axial direction of the lead screw 1.
As shown in fig. 3, the rotary sleeve 33 is provided with an inclined plane boss 331, the bushing 34 is provided with an inclined plane groove 341, the inclined plane boss 331 is inserted into the inclined plane groove 341, and the inclined plane on the inclined plane boss 331 abuts against the inclined plane on the inclined plane groove 341.
When the turnbuckle 33 is driven by the shift lever 32 and rotates around the axial direction of the screw rod 1, the inclined surface of the turnbuckle 33 can push the inclined surface of the bush 34, so that the bush 34 is driven to move along the axial direction of the screw rod 1, and the bush 34 can apply force to the stop ring 24 during movement, so that the first locking sleeve 21 is driven to move linearly along the axial direction of the screw rod 1. In the present embodiment, the linear movement distance of the bush 34 along the axial direction of the screw 1 is 1.2mm to 1.5mm, and may be, for example, 1.2mm, 1.3mm, 1.4mm, or 1.5mm. When the first locking sleeve 21 makes a linear motion along the axis direction of the screw rod 1, because the state of the limiting bead 23 located at the first position is unstable, the inner wall surface of the limiting through hole 211 of the first locking sleeve 21 can be in contact with the upper part of the limiting bead 23, and a thrust along the axis direction of the screw rod 1 is applied to the upper part of the limiting bead 23, the thrust can generate a moment to the limiting bead 23, so that the limiting bead 23 can be driven to roll, and further the limiting bead 23 enters the accommodating groove 221 of the second locking sleeve 22 through the limiting through hole 211 to complete unlocking of the screw rod 1. It should be noted that, in the present embodiment, during the unlocking process, the slope boss 331 is always located in the slope groove 341, and the slope of the slope boss 331 and the slope of the slope groove 341 are always in contact.

The unlocking operation is completed by one hand, so that the operability is strong, the time and the labor are saved, the unlocking efficiency is high, and the unlocking experience is high.
Since the bushing 34 is sleeved outside the second locking sleeve 22 in this embodiment, when the bushing 34 is driven by the rotating sleeve 33 to move, the bushing 34 also has a tendency to rotate around the axial direction of the screw rod 1, and in order to limit the tendency, and avoid the tendency to rotate from affecting the movement of the bushing 34 along the axial direction of the screw rod 1, as shown in fig. 3 and 6, a limit structure 345 is provided on the bushing 34, and the limit structure 345 cooperates with a structure in the glue gun 100, so as to limit the rotation of the bushing 34 along the axial direction of the screw rod 1.
Specifically, the limiting structures 345 are protruding limiting blocks arranged on two sides of the annular boss 342, the limiting blocks are clamped in limiting grooves formed in the inner wall of the box body of the gear box, and the limiting blocks are matched with the limiting grooves, so that the bushing 34 cannot rotate along the axis direction of the lead screw 1. Of course, in other embodiments, the limiting structure 345 may also be a limiting groove, which cooperates with a limiting block protruding on the inner wall of the box body of the gearbox, so as to limit the bushing 34.
Further, in order to improve the structural compactness of the whole unlocking mechanism 3, as shown in fig. 3 to 6, an annular boss 342 is provided in the middle of the bushing 34 along the circumferential direction, the first end 343 of the bushing 34 is located on one side of the annular boss 342, the second end 344 of the bushing 34 is located on the other side of the annular boss 342, the inclined groove 341 is formed in the annular boss 342, and the rotary sleeve 33 is sleeved on the second end 344 of the bushing 34. This arrangement can improve the rotational accuracy of the rotation, thereby contributing to the improvement of the smoothness of the driving of the bush 34 by the turnsleeve 33.
In order to limit the other side of the rotary sleeve 33 away from the annular boss 342, the glue gun 100 further includes a retaining ring 5, the retaining ring 5 is sleeved on the second end portion 344 of the bushing 34, and the rotary sleeve 33 is located between the retaining ring 5 and the annular boss 342. This arrangement prevents the swivel sleeve 33 from slipping off the second end 344. Of course, besides the retainer ring 5 being disposed on the second end 344 of the bushing 34, as shown in fig. 4, the retainer ring 5 may be sleeved on the second locking sleeve 22, and the height of the retainer ring 5 is higher than the height of the second end 344 of the bushing 34, so as to limit the rotation of the rotation sleeve 33 by the retainer ring 5 and prevent the rotation sleeve 33 from slipping off the second end 344.
In order to realize the automatic reset of the unlocking mechanism 3 after the screw rod 1 is unlocked, so as to perform the next gluing operation, the glue gun 100 further comprises an elastic reset piece 4. As shown in fig. 3 and 4, as one implementation manner, the elastic restoring member 4 is a spring located between the first locking sleeve 21 and the second locking sleeve 22, and one end of the spring is connected to the first locking sleeve 21, and the other end is connected to the second locking sleeve 22. When the first locking sleeve 21 is driven by the unlocking mechanism 3 to perform linear motion along the axis direction of the screw rod 1, the spring is compressed, and after the unlocking button 31 is stopped being pressed, the elastic force of the spring can drive the second locking sleeve 22 to perform reverse linear motion, so that resetting is realized, and the locking mechanism 2 is restored to a limiting state from an unlocking state. Of course, besides the spring, a wave-shaped elastic sheet or other elastic structure can be used as the elastic restoring member 4.

When the ramp boss 331 is inserted inside the ramp groove 341, the first ramp 333 and the second ramp 346 abut, and the third ramp 334 and the fourth ramp 347 abut. The first inclined surface 333 and the second inclined surface 346 are matched, and the third inclined surface 334 and the fourth inclined surface 347 are matched, so that the bushing 34 can move along the axial direction of the screw rod 1 when the turnbuckle 33 rotates clockwise or anticlockwise, and the screw rod 1 is unlocked.
Alternatively, the ramp boss 331 having the first ramp 333 and the third ramp 334 is a triangular structure protruding from the swivel nut 33, and the ramp groove 341 having the second ramp 346 and the fourth ramp 347 is a triangular groove opening from the bushing 34. Of course, in addition to the triangular structure and the triangular groove, the inclined plane boss 331 may also be a trapezoidal structure, and the inclined plane groove 341 may also be a trapezoidal groove.
