the reset spring 10 is a tower spring. Under the action of the tower spring, the handle 5 can return its original position automatically.
a control mechanism that can lock the drive unit when it is far away from the staple magazine 3 is disposed in the gun body 1.
the control mechanism comprises a through hole 2a disposed in the drive unit 2, a locking pin 6 disposed in the gun body 1, a locking pin pipe 7, a torsion spring 8 and a trigger 9.
One end of the locking pin 6 penetrates the locking pin pipe 7 and connects to the through hole 2a, and the other end connects to the trigger 9.
One end of the torsion spring 8 acts on the locking pin 6 and the other end acts on the gun body 1.
locking pin 6 In initial state, under the action of the torsion spring 8, locking pin 6 withstands the drive unit 2. During the drive unit 2 moves away from the staple magazine 3 along the slot, the locking pin 6 inserts into the through hole 2a of the drive unit 2 and locks the drive unit 2. When the staple gun needs to work, just press the trigger 9 lightly, then the locking pin 6 breaks away from the through hole 2a of the drive unit 2, a staple will be driven into where it is needed.
the position limit mechanism comprises a rebounding pillar 11, a position limit spring 12 and a screw cap 13. At one end of the rebounding pillar 11, there is a prominent baffle 11 a and at the other end there is screw threads that connects to the screw cap 13. The rebounding pillar 11 penetrates through the handle 5 and connects with the screw cap 13 fixedly.
the position limit spring 12 is wrapped around the rebounding pillar 11. One end of the position limit spring 12 acts on the baffle 11a of the rebounding pillar 11, and the other end acts on the handle 5.
the position limit spring 12 wrapped around the rebounding pillar 11 is compressed.
the baffle 11 a of the rebounding pillar 11 withstands the leaf spring 4.
the handle 5 When the handle 5 is depressed, the end of the leaf spring 4 acting on the drive unit 2 moves away from the staple magazine 3 along the slot together with the drive unit 2.
the baffle 11 a withstands the leaf spring 4 while overcoming the force produced by the position limit spring 12 and then forces the screw cap 13 to separate from the handle 5.
the position limit spring 12 is compressed further.
the control mechanism locks the drive unit , then the handle breaks away from drive unit. Under the action of the reset spring 10, the handle 5 would like to reset.
the position limit spring 12 is also compressed which leads a tendency that the distance between the handle 5 and the leaf spring 4 would increase.
the position of the leaf spring 4 and drive unit 2 is locked by the control mechanism, so the handle 5 could not reset and completely separates from the connecting hole 2b.
the trigger 9 of the control mechanism is pressed, the locking pin 6 breaks away from the through hole 2a of the drive unit 2 to drive a staple as normal. Then the handle 5 returns to its original position only by the action of the reset spring 10 and then is ready for use next cycle.
the rebounding pillar 11, position limit spring 12 and the screw cap 13 are very important. Without them, when the handle 5 moves to the certain position, the locking pin 6 inserts into the through hole 2a of the drive unit 2, and the handle 5 breaks away from the connecting hole 2b. In that case, if the user releases the handle 5, the reset spring 10 bounces the handle 5 at once and the end of the handle 5 inserts into the connecting hole 2b again. Then if the trigger 9 is pressed, the locking pin 6 breaks away from the through hole 2a. The drive unit 2 and the handle 5 bounce together at the same time. As a result, the user may be hurt and the staple may not be driven efficiently.
the manual staple gun is used to drive a staple into softwood or other soft materials.
the conventional manual staple gun works as below. Staples are placed in the staple magazine 3 in rows. As the staple magazine 3 connects with the slot of the gun body 1, the staple at the end of the staple magazine 3 is delivered into the slot. Press down the handle 5, and it will force the firing pin 2 to move away from the staple magazine 3 along the slot.
the leaf spring 4 acting on the drive unit 2 produces spring force. When the handle 5 moves to a certain position, it breaks away from the drive unit 2. Under the action of the spring force produced by the leaf spring 4, the drive unit 2 drives the staple at the end of the staple magazine 3 out.
the staple gun has a control mechanism that can lock the drive unit 2 when it is far away from the staple magazine 3 along the slot in the gun body 1.
the handle 5 can be depressed on the ground in advance and the drive unit 2 can be locked by the control mechanism.
a staple can be driven into where it is needed.
