Labor-saving stapler

Abstract

The invention relates to a force-saving nailing machine. The force-saving nailing machine comprises a housing, an impacting plate, a force storing mechanism, an operating mechanism and a limiting mechanism, wherein the housing is provided with a nail outlet; the impacting plate is arranged in the housing and can move to a ready position far away from the nail outlet and a nail discharging position close to the nail outlet; the force storing mechanism comprises a connecting part which is arranged on the housing, and a connecting end which is in linkage fit with the impacting plate; the force storing mechanism is provided with a force storing state and a releasing state which can be switched; the operating mechanism is movably arranged on the housing and comprises an abutting part; the abutting part can abut between the connecting part and the connecting end; the limiting mechanism is arranged on the housing and can be used for clamping and positioning the impacting plate; when the impacting plate is in the ready position and is clamped and positioned by the limiting mechanism, the force storing mechanism can be abutted by the abutting part of the operating mechanism to be in the force storing state; and when the impacting plate is not clamped and positioned by the limiting mechanism, the force storing mechanism links the impacting plate to move towards the nail discharging position.

Description

Technical field [0001] The invention relates to a nailing machine, and particularly relates to a labor-saving nailing machine. Background technique [0002] The existing nailing guns can refer to the patents described in Taiwan Patent No. I336286 and US Patent No. US 6,789,719, which mainly use the swing of the handle to drive the internal connecting rod of the nailer to swing, and further move the straight sliding striker to the At the firing position, at the same time, the impact plate is pressed by the spring or shrapnel, and while moving toward the firing position, the shrapnel bends and accumulates force. When the connecting rod swings further and separates from the strike plate, the impact plate is affected by the shrapnel. The elastic force moves down quickly, firing the nail. [0003] Such nail guns are laborious and complicated in actual use. Because the mechanism of the nail gun releasing the striker plate is achieved by automatically separating the swinging connecting ...

AI Technical Summary

Problems solved by technology

[0003] This type of nail gun is relatively laborious and complicated in actual use

Since the mechanism of this type of nailing gun to release the striker is achieved by the automatic separation of the swinging connecting rod and the linearly moving striker, when the connecting rod is worn out due to long-term use, the timing of the release of the striker will be advanced, which may cause Insufficient shrapnel stroke and inaccurate needle firing

Secondly, if the position of the striker and the connecting rod is slightly changed due to production errors or due to external impact, the timing of the release of the striker will change, and it may even happen that the striker cannot be released or released early

[0004] In addition, when this type of nailing gun is not in use, the striker plate remains at the fired position and keeps in contact with the nail needle in the nail gun. After the striker plate is moved by the connecting rod, the nail needle moves forward to the correct position. Only in this position can the needle be fired smoothly. If the user uses it quickly and continuously, the striker will easily hit downward before the needle moves to the correct position, causing the needle to be squeezed abnormally, blocking the exit of the needle. cause damage
