    • A hot melt glue gun is described and claimed having a rod feeding mechanism (14) comprising a trigger (50) arranged to drive clamping means to grip a rod of adhesive and to move the rod towards a melt chamber (17) of the gun. The clamping means comprises a carriage (42) movable towards and away from the melt chamber and having a shaped portion (110) to accept a rod to be fed. The clamping means also comprises, pivoted on the carriage, a clamp member having a clamping arm portion (71) for gripping the rod against the shaped portion, and a crank arm portion (70). The crank arm portion has an operating portion (49) having a convex surface (64) arranged to co-operate with pressure means (207) of pivotally mounted connecting means (52). The connecting means is positioned to be operated by the trigger. By virtue of the disposition of the pivots and the clamping arm and of the shaping of the operating portion of the crank arm, there is brought about an improved usage of triggering effort to feed the rod. The clamping arm portion is disposed and shaped to grip the rod with reduced disfiguring and distortion of the rod.
    • 一种热熔胶枪描述和要求具有一个杆进给机构(14),其包括一个触发器(50),该触发器设置成驱动夹持装置来夹持一根粘合剂杆,并使该杆朝向枪的熔化室(17)移动。 夹紧装置包括可朝向和远离熔化室移动的托架(42),并且具有成形部分(110)以接受待进给的杆。 夹紧装置还包括在滑架上枢转的夹紧构件,具有用于将杆夹在成形部分上的夹紧臂部分(71)和曲柄臂部分(70)。 曲柄臂部分具有操作部分(49),该操作部分具有凸出表面(64),该凸表面布置成与枢转地安装的连接装置(52)的压力装置(207)配合。 连接装置定位成由扳机操作。 由于枢轴和夹持臂的布置以及曲柄臂的操作部分的成形,引起了对杆的进给的触发力的改进的使用。 夹持臂部分被设置和成形以便以较小的棒的变形和变形来夹紧杆。
